2. Phase-style feeding function: It can input 20 groups of different feeding length, each group provides punching for 999 times to satisfy the processing and production of special products (option)

3. Manual model: It can input 3 phases manual speed, which can let used operate more easily and feed materials more accuracy.

4. High efficiency release device: It can set up release angle quickly, only match cam signal and adjusted feed thickness can done.

5. Feeding length setting: Input feed length on the controller panel directly.

6. Feeding unit: The roll adopts middle-hollow style. Being light and with low inertia for electroplate. The surface hardness HRC is 60 and hard chrome plated.

NC Servo Feeder Working Principle
NC feeder is also known as the servo feeder. It is an automatic equipment that realizes accurate feeding by rollers through a synchronous pulley driven by a complete CNC system such as PLC, servo motor and servo driver.
According to the different relaxation actions, NC feeder is generally divided into two categories: pneumatic NC feeder and mechanical NC feeder. The feeding principle of these two feeders is exactly the same; the difference is how to achieve the relaxation action.

The control system of the NC servo feeder machine consists of PLC, servo system and touch screen. PLC can improve the stability of the control system and enhance the anti-interference ability of the system. The servo system can accurately position the mechanical movement and improve the accuracy of the mechanical transmission. The touch screen can visually display and modify NC feeder parameters which simplify on-site operation.

PLC is the core component of NC servofeeder. KINGLAN NC feeder is equipped with Siemens PLC. It has built-in high-speed pulse output function, which can directly send quantitative pulse number to control servo drive operation. The servo driver controls the rotational position and speed of the servo motor according to the number of pulses and the channel emitted by the PLC pulse output terminal, thereby accurately giving the feed length. The touch screen can visually display various parameters of the system, providing users with a good human-interface screen and simplifying on-site operation.

When in the manual mode, the ACC (frequency acceleration/deceleration control) command is executed at the rising edge of the servo forward signal, and the mode control data is set to realize the CW (clockwise) direction rotation to make the servo motor rotate forward. At the falling edge of the servo forward signal, the INI (operation mode control) command is executed to stop the pulse output. The servo motor reversal situation can be analogized.

When in the automatic mode, the PLC sends a preset pulse to the servo drive, and the PLS2 (positioning) command is executed at this time.

Compound Die(2020年05月30日)

KINGLAN — 2020-05-28T16:22:42+0900

http://www.kinglanpress.com/products/compound-die.html

Compound die stamping refers to a die structure in which a press machine completes blanking, punching and other processes in one stroke.

Compound Die Classification
(1)Blanking compound die set: such as blanking and punching or cutting and punching etc.
(2)Forming compound die: such as bending, extrusion etc.
(3)Blanking and forming compound die: such as blanking and deep drawing; punching and flanging; deep drawing and trimming; blanking, deep drawing, punching and flanging etc.

Compound Die Set Features
1. Production efficiency is highly increased.
2. Quality of stamping parts improved
3. Concentricity error of compound die is within +/-0.02 ~ +/-0.04mm.
4. High requirements for die manufacturing accuracy

Because the compound die needs to complete several stamping processes in one die, the die structure is generally more complex than single station die. And the components require no interference, accuracy, and reliability during operation which requires a high manufacturing precision. Therefore, the manufacturing cost of the compound die is also increased, the manufacturing cycle is relatively extended, and the maintenance is not as simple as the single process.

Principles of Selecting Compound Dies
1.Volume production
2.High-volume is more suitable for using compound die.
3.Precision of stamping part
4.When the precision and concentricity of the stamping parts are highly required; the shape is complex, and repositioning the stamping part may produce large errors, the compound die should be considered.
5.The number of compound processes

Generally, the number of compounding processes for the compound die is less than four. More processes will cause die structures overly complex. At the same time, the strength, rigidity, and reliability of the die will also decrease, making it more difficult to manufacture and maintain.

Discharge and Knock off Device
In the compound die, since there are more actions to be completed in one stroke of the press, in order to simplify the mold structure, some auxiliary actions, such as discharging and knocking off are usually performed by using elastic devices. At the same time, the elastic device can also allow the stamped work piece to be pressed throughout the stamping process, so that the stamped work piece has better flatness.

Mold Base selection
Because the precision of the compound mold is higher, its mold base should also be selected with higher accuracy. The ball type mold base has the advantages of high precision and long service life compared with the slide type mold base, so the ball type is often used.

The mold seat in the mold base is often made of steel plate by replacing the ordinary cast iron

For complex compound dies that require high precision, spherical floating die shanks can be used to reduce the adverse effects of stamping equipment or die mounting errors on the die. It should be noted that when the floating shanks are used, the guide posts cannot leave the guide bush, otherwise severe machine and personal accidents may occur.

It can also process stamping for complex graphic products. Specifically, let’s look at the power press auto feeder application installation case!

In the use of the power press auto feeder, the raw materials are fixed by the pneumatic machinery, and a zero point position is set. After that, the feeding system automatically sends the coffin to the punching position below the punch punch according to the shape of the required punching hole. After punching a hole, the punch is automatically lifted, and the feeding system sends the next punching position of the coffin to the punch below the punch. Repeating the flushing until it is completely flushed back to the zero position as required.

The overall application of the power press auto feeder is to place the material on the fixed frame of the automatic feeder, fix it by air pressure, and then input the corresponding data into the operation interface dialog box of the feeding system according to the size of the coffin and the required product. In the parameter column, after the operator inputs the value, the system will automatically calculate according to the filled data, eliminating the complicated human calculation and programming process and realizing automatic production. It is also possible to perform a separate jog operation according to customer requirements.

Introduction of Pneumatic Punch Press Feeder(2020年05月28日)

KINGLAN — 2020-05-28T16:19:25+0900

http://www.kinglanpress.com/introduction-of-pneumatic-punch-press-feeder.html

Description: Pneumatic punch press feeder is an earlier machine used for punch feeding. It has two forms: active feeding and passive pulling. Active feeding is suitable for general materials. Materials are fed into the die by feeder; passive pulling is suitable for thin or soft materials, mainly used for feeding products with low precision and low speed.

Performance characteristics:
1. Pneumatic punch press feeder is an earlier machine used for punch feeding. Its main characteristics are: simple operation, convenient installation and affordable price. It is mainly used in the delivery of products with low precision and low speed.
2.This machine has two forms: active feeding and passive pulling. Active feeding is suitable for general materials, and materials are fed into the die by feeder; passive pulling is suitable for thin or soft materials. The feeder is installed in the direction of the outlet of the die, and material is pulled out by pneumatic punch press feeder to avoid material bending.
3. Standard fittings have three combination sets (water filter, air filter, pressure regulation), one high-pressure pipe (connecting air source and air feeder air path, transmitting power source to feeder), one L-type installation plate (used to install air feeder on punch), one set of guide rod, one set of sealing ring and one buffer (AF-5C starting equipment), which can make rapid feeding achieve lower vibration effect).
4. Standard pneumatic punch press feeder adopts the method of floating rod feeding, through the guide rod mounted on the slider, to complete the feeding action, and the machine itself does not have relaxation function. If the upstream and downstream journey of the press is too short or too long, the E-type feeding solenoid valve should be installed to replace the floating rod to complete the feeding; while the R-type relaxing solenoid valve is suitable for the case of high precision feeding, using the solenoid valve to relax the fixed splint to correct the error, the actual selection should be based on your specific needs.

Mechanical Press Machine Working Principle(2020年05月28日)

KINGLAN — 2020-05-28T16:14:03+0900

http://www.kinglanpress.com/mechanical-press-machine-working-principle.html

The design principle of the mechanical press machine is to convert the circular motion into a linear motion, and the main motor outputs the force to drive the flywheel. The clutch drives the gear, the crankshaft (or the eccentric gear), the connecting rod, etc. to achieve the linear motion of the slider. The motion of the motor to the connecting rod is a circular motion. There is a need for a circular motion and a linear motion transfer point between the connecting rod and the slider. The design has roughly two mechanisms, one is a spherical type and the other is a pin type (cylindrical type), and the circular motion is performed via this mechanism to a linear motion of the slider. The presses release the force on the material to plastically deform it to obtain the required shape and precision. Therefore, it is necessary to match a set of molds (dividing the upper mold and the lower mold), placing the material between them, and applying pressure by the machine to make it deformed, the reaction force caused by the force applied to the material during processing is absorbed by the mechanical body of the press.
