punching machine - working principle

- Jun 11, 2018-

The working principle of punch:


          The design principle of the punch press is to convert circular motion into linear motion. Driven by the main motor, the flywheel is driven, and the clutch is used to drive the gear, the crankshaft (or eccentric gear), the connecting rod, etc. to achieve the linear motion of the slider, and the movement from the main motor to the connecting rod is a circular motion. There must be circular and linear movement between the connecting rod and the slider. There are roughly two types of mechanism in the design, one is a ball type, and the other is a pin type (cylindrical type). Through this mechanism, the circular motion Converts the linear motion of the slider.


          Presses apply pressure on the material to plastically deform it to obtain the required shape and precision. Therefore, it is necessary to cooperate with a set of dies (separate upper and lower dies) to place the material between them and apply pressure to the machine to deform it. The reaction force caused by the force exerted on the material during processing is absorbed by the punch machine body.
