What is Metal Leveler Machine?
The so-called straightening machine sheet leveler machine is simply equipment for straightening metal profiles, bars, pipes, wires, etc. The working principle of this kind of metal forming machine is to change the straightness of bars etc. through the straightening rollers. Generally speaking, the leveler machine has two rows of straightening rollers, of course there are exceptions. The two-roll leveler machine usually straightens materials of different diameters by relying on the angle change of the two rolls. leveler machines can be divided into pressure leveler machines, balanced roll leveler machines, shoe roll leveler machines, rotary reverse bending leveler machines and so on.

Straightening Process of Sheet Leveler Machine

When the sheet leveler machine is working, the position of its rollers is at a certain angle with the direction of movement of the product to be straightened. Two or three large ones are active pressure rollers, which are driven by the motor to rotate in the same direction. Several small rollers on the other side are The driven pressure rollers are rotated by the friction of the rotating rod or tube. In order to achieve the required compression of the product by the rollers, these small rollers can be adjusted forward or backward at the same time or respectively. Generally, the more the number of rollers, the higher the accuracy of the product after straightening by sheet leveller. After the product is bitten by the roller, it continuously moves in a straight line or rotates, so that the product undergoes various deformations such as compression, bending, and flattening, and finally achieves the purpose of straightening.

Fine Blanking(2023年06月01日)

boyamachinery — 2023-06-01T11:29:18+0900

BOYA fine blanking production division, the products are good stability and reliability, high degree of automation, high production efficiency, simple operation and ergonomic. For localization of high-end intelligent fine blanking equipment, raise the capacity of fine blanking production, After years of research and development, design and manufacturing, 320 tons, 630 tons, 700 tons of hydraulic fine blanking machines have been successful production and operation.

What is Fine Blanking?
Precision blanking. Including strong blanking precision blanking, precision blanking to concave die and flat blanking precision blanking. Automotive precision punching parts production to strong blanking precision blanking. The geometric shape, dimensional tolerance, shape and position tolerance and shear surface quality of fine blanking parts are much higher than ordinary blanking parts, fine blanking process plays a great role in the field of automotive parts manufacturing.

Working Principle of Fine Blanking

Compared to normal blanking, fine blanking operation is more precious, product high precision requirements, no collapse Angle, no burr, the full bright belt is the difficulty of stamping process, the use of ordinary blanking process cannot avoid burr, collapse angle.

Fine blanking technology is a special method to solve this kind of product.

Fine Blanking Advantages
Fine blanking china is a kind of chipping-free processing technology, which is a precision blanking method developed from the general blanking technology. Fine blanking ensures that the punched surface of the punched part is free of cracks and tears over its entire material thickness. In addition, the tightest dimensional accuracy and flatness tolerances can be achieved. Fine blanking is able to obtain high quality fine blanked parts with higher dimensional accuracy, cleaner blanking surface, less warpage and better interchangeability than normal blanked parts in one punching stroke, and to achieve improved product quality at a lower cost.

Fine Blanking Process
There is a fundamental difference between the process characteristics of fine blanking and normal blanking. While normal blanking controls the tearing of the sheet during the blanking process, fine blanking does everything possible to inhibit the tearing of the sheet during the blanking process. Fine blanking design remains as one piece until the part is separated from the sheet, and the sheet metal is always in a plastic deformation process during fine blanking. To achieve this, the V-rim and counterpress are used to hold the sheet before punching to prevent the sheet from moving inside or outside during the punching process. In addition, together with the small gap between the convex and concave dies and the appropriate small rounded corners of the concave die, a three-way compressive stress state in the local area of the punching is formed during the punching process, thus ensuring the plastic deformation process of the punching. Moreover, the fine blanking material and lubrication state also have a great influence on the effect of fine blanking operation. The material with good plasticity, low deformation resistance, complete spheroidization, good dispersion and uniform distribution of fine spherical carbide organization is most suitable for fine blanking. A good lubricant not only improves the quality of the fine blanked parts, but also helps to reduce the wear of the die and improve the service life of the die. The fine blanking process requires precise punching force, crimping force and counter pressure of the fine blanking equipment.

Fine Blanking Applications
Fine blanking technology can be applied to various applications such as automobile, motorcycle, computer, video recorder, communication equipment, aircraft manufacturing, home appliances, office machinery, optical components, and construction industry etc. There are nearly 8000 kinds of parts produced by fine blanking, about 50%~60% of fine blanking parts are used in automobile industry, such as rack, tooth plate, cam on seat adjuster; ratchet, pawl, adjusting tooth plate, pull arm, push rod, web, support plate, etc. in brake system; lock plate, card plate, safety block, etc. in car lock; latch, inner gear ring, pawl, etc. in seat belt; follower plate, etc. in clutch; transmission Fork, etc.; transmission system flange, thrust gasket, etc.; door glass lifter gear plate, etc. Many of the stamped parts on these automobiles are produced by the fine blanking process. Boya is one of the leading fine blanking companies and fine blanking suppliers in China and we can offer a complete fine blanking services and solutions to our customers.

Fine Blanking VS Stamping
Fine blanking originated from general stamping, but it is not simply an enhanced version of general stamping. The essential difference between the fine blanking process and the general blanking process is that the general blanking cannot effectively avoid the generation of tears in the section when punching, while the fine blanking tries to inhibit the occurrence of tears in the sheet material by all means when punching. The following are the differences between fine blanking and general stamping.

1. Difference in requirements of materials to be processed
Ordinary stamping can process almost any material, as long as the die steel is strong enough and the press pressure is sufficient.

However, the materials used for fine blanking require good plasticity, low flexural strength ratio and high elongation of the material to be processed because of the need to effectively transfer compressive stress between material crystals to inhibit cracking.

2. Differences in processing capacity characteristics
General punching limit size

Stamping: Minimum hole diameter of 1.5 times the material thickness.

Fine blanking: minimum hole diameter up to 0.6 times the material thickness.

Dimensional accuracy

Stamping: Normal dimensional accuracy, IT14.

Fine blanking: High dimensional accuracy, IT6~9.

Cold work hardening

Stamping: partial cold work hardening of section collapse and bright zone.

Fine blanking: cold hardening of the whole section, which can improve the strength of the contact surface. 4.

3. Difference in equipment used
Ordinary stamping equipment generally provides one-way power (there are also double power presses to process special-shaped products), i.e. punching force. However, fine blanking operation machines can provide three power forces, punching force, crimping force and counter-top force. And the fine blanking press is compact and has a small table surface. The table length of fine blanking machines of about 800T is generally about 1m. Of course, like ordinary stamping machines, fine blanking machines also need other supporting auxiliary equipment. The necessary auxiliary systems for general fine blanking machines are uncoiling and leveling feeder, die lubrication system and parts waste separation system.

Suitable for processing cold rolled and hot rolled carbon steel, silicon steel, tinplate, stainless steel and coated metal materials. According to the application, the equipment can be classified as silicon steel transverse shear line (transformer core transverse shear line), stainless steel transverse shear line, copper foil aluminum foil transverse shear line, cardboard transverse shear line and so on. According to its electronic control type can be classfied into CNC transverse shear line, pneumatic transverse shear line and so on.

Cut To Length Machine during High Speed Cut Blade Temperature Impact
Based on the pursuit of coil cut to length machines efficiency, we need to increase the shear speed and reduce cutting time. However, while increasing the shear speed, the working temperature of the ctl machine blade rises, the force is large, causing the blade to accelerate wear. On the other hand, the blade is affected by the heat expansion, and further affects shear quality.

In the initial stage of the shear, the overall temperature of the steel cut to length machine is raised. As coil processing machinery shear is stable, the blade is in contact with the strip, the high-temperature area is increased, and the remainder temperature is slightly reduced; after shear enters the steady-state, the blade edge temperature Although it increases, the increase is gradually reduced until it is stable in a constant temperature.

What's Tension Leveler Unit?
Tension Leveler machine (stretching-bending straightener ) is a kind of metal strip shape righting equipment, to stretch and bend the strip to remove the three-dimensional defects such as wave, buckling, camber, etc and improve strip shape quality. Under the coordination of tension and bending stress, the tension leveler machine can make the strip extend with lesser tension.

Working Principle of Tension Leveler
01
The basic principle of strip shape righting: Make the strip extend moderately, when the external force disappears, the elastic deformation will return, and the plastic deformation will remain so that the deformation of the metal fiber eventually tends to be consistent, so as to correct the three-dimensional defects of the strip. This extension is measured in terms of elongation. Operating the tension leveler is actually operating the elongation.

02
Tension leveler is composed of two inseparable parts, they are bridle roll unit and the host (we are often referred to as the tension leveler machine). In order to correct the shape of the plate to the ideal state, the bridle rolls should be able to provide enough tension, and the tension leveler machine should be able to provide enough bending stress. In order to provide sufficient tension, the bridle rolls must have the right diameter, right friction coefficient, right power system, but also the right initial tension. The initial tension is provided by the equipment before and after the tension leveler unit. So as to provide enough bending stress for the tension leveller, first of all, the frame and the roller cassettes should have enough stiffness and strength, and the quickly opening cylinder should have enough diameter, and the lifter should have enough tonnage.

03
Elongation is the goal of the tension leveler unit. The elongation is derived from the difference of the speed among the bridle rolls before and after the tension leveler (achieved by electronic control) and is directly related to the tension provided by the bridle roll, also is related to the wrap Angle of the work roll with the strip.

What's The Function of Tension Leveler In Galvanizing Line

The tension leveler machine is usually installed after skin pass mill in the continuous galvanizing unit. After the annealing galvanizing and skin pass process, the strip defect can be removed by the tension leveler machine to obtain good product quality.

Specifically:

1. Get good surface quality. Under the action of leveling, bending, and straightening of tension leveler machine, strip defects such as strip wave, side wave, wavy, buckling and camber can be effectively eliminated, the flatness of the strip is significantly improved.

2. Eliminate yield platform and improve the reprocessing performance of sheet. After the strip is annealed and galvanized, the yield platform will appear on the material strain curve. Under the influence of the yield platform, the finished sheet will have poor stamping forming performance and easy to produce wrinkles during the subsequent processing of customers, which will seriously affect the product quality. Therefore, the cold rolled annealed sheet must eliminate the material yield platform, but the excessive deformation will cause new processing hardening for the sheet, the plasticity of the material will decline, the yield stress will rise again, to maximum elimination of yield platform used by the elongation. The yield platform can also be eliminated by skin pass mill, but in the process, the strip surface will only be deformed. After the elimination of the yield platform, a faster aging recovery will occur, so the elimination is temporary. The tension leveller can make the whole section of the strip deformed, and the deformation is in the vertical direction, transverse and longitudinal three degrees, the strip is not easy to produce aging recovery.

3. Eliminate the anisotropic of sheet, cold rolled low carbon steel in deep drawing process, the yield limit of material in transverse and longitudinal often showed obvious anisotropy, make the punched part uneven thickness in two directions, has lace skirt shape defects and not easy for deep forming. Through the proper process of tension leveler machine, sheet yield limit anisotropy is obviously improved, The deep punching performance of sheet is improved effectively.

In industrial production, people have been sparing no effort to increase the utilization rate of raw materials. However, the emergence of waste is always inevitable.

The recycling of scrap is of great significance at all times. We have to consider how to recycle them so that the efficiency can reach a higher standard.

As far as the iron and steel industry is concerned, for every ton of scrap iron and steel recycled and used, 850 kilograms of steel can be made, which can save 20 tons of iron ore and 1.2 tons of standard coal compared to steel making with iron ore.

There is a huge gap between the supply and demand of scrap steel resources. Only by accelerating the pace of existing scrap steel recycling, increasing the scrap steel recycling rate, and vigorously strengthening the development and utilization of scrap steel can we better meet the needs of industrial development. The recycling of waste is not only a cost recovery, but also an investment in the environment.

https://www.boyamachinery.com/products/scale-breaker/

Scale Breaker
Scale-breaking tension leveller, also called scale breaker, is generally used for continuous pickling units. Scale breaker machine applies to bend stress to strip steel. The front and rear bridle roll applys tensile stress to the strip; Under the coordination of these two stresses, the strip can produce moderate elongation under the condition that the tensile stress is far below the yield limit of the material. On the one hand, this extension realized by scale breaker can improve the shape of the strip and eliminate the defects such as wave, buckling and camber, at the same time, the internal stress and yield platform are eliminated to improve the mechanical properties of the strip. On the other hand, due to the huge difference between the oxide layer on the surface of strip steel and the iron matrix in performance, under the action of bending and stretching, a large number of oxide layer will fall off, and the oxide layer still attached to the surface will also crack, so as to improve the efficiency of acid tank pickling descaling.

Rewinding Line(2023年)

boyamachinery — 2023-04-06T12:09:35+0900

https://www.boyamachinery.com/products/rewinding-line/

Rewinding line and recoiling lines will encounter the problem of strip skidding during the actual usage which can lead to production barriers like strip deviation, at the meantime, coil processing lines can affect the security of production equipment. With the pressure roller, tension rolls for the rewinding unit can prevent the strip from slipping on the surface of the rolls and get initial tension.

BOYA Rewinding Line Features

The force increase of tension roller unit was achieved by wrapping effect of each tension roll.

In the condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface.

Rewinding Line Working Principle
01
The recoiling line running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force.

02
The slipping of any tension roll unit will cause scratches to the surface of the strip. In the rewinding line, the light damage can degrade product quality, while the heavy one will scrap the strip. So the slipping of the tension roll unit is extremely harmful to production.

03
At the same time, the slipping of any tension roll unit will have a direct effect on itself, which can make the roller surface smoother and smoother. The friction coefficient diminished rapidly, so we need to regrind the roll surface and the roll usage period will be shorted. In addition, the skidding of tension roller unit can cause motor output torque to fluctuate, impact the transfer decelerator, make gear failure and defect the decelerator.

04
In order to prevent slipping, rewinding line diameter is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of coil processing line strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface.

05
Although we cannot eliminate the slipping of tension roll through the way of improve the electrical control of tension roller unit, we can provide the reasonable and perfect electrical control method which can benefit to diminish the degree of slippage. Therefore, we can decrease the wear of tension roll, and it is helpful for us to find and correct the slipping.

Work Roll

BOYA produces slender rolls such as smooth roll (can be chromed), spiral roll (can be chromed), and concave roll. There are more than 10 kinds of rolling mill rolls we can manufacture. The highest surface hardness of work rolls and intermediate rolls we manufactured is HRC65, with a length between 607-3960 mm and diameter between ∮16-400 mm. the biggest hollow roll we produced now is ∮ 600 mm. BOYA uses special work roll material to produce steel sheet roller used in tension leveler of pickling line. These work roll are applied to many industrial giant and their working performance is as good as the original.

Details of Work Roll

In steel rolling, the work roll is in direct contact with the strip to produce deformation and finally get the roller of the product. The active roll driven by the motor is the work roll. In the manufacture of work roll, the metallurgical quality of the roll should be strictly controlled or supplemented by external measures to enhance the bearing capacity of the roll. Reasonable roll shape, hole shape, deformation system and rolling conditions can also reduce the working load of rolls, avoid local peak stress and prolong work roll chock life. The consumption of work roll depends on three factors:

Rolling mill, material and rolling condition, and the reasonable choice of roll;

Work roll material and manufacturing quality;

Roll use and maintenance system.

Working Principle of Tension Leveler
01
The basic principle of strip shape righting: Make the strip extend moderately, when the external force disappears, the elastic deformation will return, and the plastic deformation will remain so that the deformation of the metal fiber eventually tends to be consistent, so as to correct the three-dimensional defects of the strip. This extension is measured in terms of elongation. Operating the tension leveler is actually operating the elongation.

Tension rolls for rewinding unit will encounter the problem strip skidding during the actual usage which can lead to the production barrier like strip deviation, at the meantime, it can affect the security of production equipment. With the pressure roller, tension rolls for rewinding unit can prevent the strip from slipping on the surface of rolls and get initial tension.

The Features of BOYA Rewinding Line and Recoiling Line
The force increase of tension roller unit was achieved by wrapping effect of each tension roll.

In condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface.

Working Principle of Rewinding Line
01
The running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force.

04
In order to prevent slipping, the diameter of tension roller unit is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface.

Reason Analysis For The Burr After Side Trimmer In Hot Rolling Pickling Line

BOYA side trimmer is one of the key equipment of pickling line or PLTCM. The function of this metal shear machine is to trim the edge of raw materials according to the width of finished products and remove the quality defects of raw materials at the same time, to avoid quality degradation, belt breaking, and other accidents. Burr refers to the raw material in the edge-cutting treatment, the appearance of "hair-like" quality defects at the edge of the strip. Its harm is that the burrs are easy to cause the strip broken in rolling process; The burrs fall off from the edge will stick to the rolls to cause the indentation defect on the surface of the cold-rolled product; The residual burr after cold rolling will affect the quality of subsequent galvanizing and cause the strip broken after annealing. The main reasons for burrs are:

Hot rolling raw material defects

Uneven width, edge wave, edge wrinkle, edge crack and other quality defects of hot rolling raw materials will impact the blade edge of the trimming, resulting in the blade edge collapse, or lead to the trimmer edge cutting failure or slip blade, resulting in burr

The clearance calculation has changed

The shear Gap is determined by both Gap and Lap. The mathematical model used for clearance calculation is based on the theoretical cross-section of hot rolled material. The theoretical hot rolling material has good consistency of cross-section, few edge drop and no wedge. In fact, the cross-section structure of hot rolling materials used in cold rolling mills of various steel mills is not the same, and hot rolling materials have their own unique cross-section structure, so there is a deviation between theory and practice

Clearance calibration is not accurate

Trimming edge gap jump

The gap jump of the trimming edge is produced by the coordination of upper and lower cutting edges. The cutting edge is fixed on the shaft head of the cutting seat by the hydraulic nut, and the expansion ring is pressed outward by the locking screw. When the hydraulic nut is not properly fastened, the axial force is insufficient in the process of vertical strip cutting edge, resulting in the axial jitter of cutting edge and the jump of cutting edge gap.
