Introduction to the function and principle of high-speed punch press

1. The function of high-speed punch press balancer

1. The function of high-speed punch press balancer: High-speed punch press automatic punch press spring balancer: High-speed punch press has a structure that prevents high-speed punch press parts from flying when springs and other parts are damaged.

2. Automatic punching machine pneumatic balancer (most precision punching machines use this type, also known as balance cylinder):

① High-speed punching machine has a structure to prevent high-speed punching machine parts from flying when the piston and other parts are damaged.

② When the automatic punching machine brake device is not activated, the high-speed punching machine keeps the punch and high-speed punching machine accessories at any position of the stroke, and has a structure that automatically stops the movement of the slider when the air pressure is lower than the set pressure, which has higher safety performance.

2. Working Principle of High-Speed Punching Machine

The design principle of high-speed punching machine is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel. The high-speed punching machine drives the gears, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to achieve the linear motion of the slider. The movement of the high-speed punching machine from the main motor to the connecting rod is circular motion. There must be a transfer point between the circular motion and the linear motion between the connecting rod and the slider of the high-speed punching machine. There are roughly two types of mechanisms in the design of high-speed punching machine, one is ball type and the other is pin type (cylindrical type). Through this mechanism, the circular motion is converted into the linear motion of the slider.

The high-speed punch press applies pressure to the material, causing it to deform plastically and obtain the required shape and precision. Therefore, a set of dies (upper die and lower die) must be used to place the material between the high-speed punch presses. The machine applies pressure to deform the high-speed punch presses. The reaction force caused by the force applied to the material during processing is absorbed by the punch press machine body.
