How stamping press works
The design principle of the punch is to convert the circular motion into linear motion. The main motor outputs the power to drive the flywheel. The clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. From the main motor to The movement of the connecting rod is circular.
There is a transition point between circular and linear motion between the connecting rod and the slider. There are roughly two mechanisms in the design, one is ball type, and the other is pin type (cylindrical type). Converted into linear motion of the slider. The punch presses the material to plastically deform it to obtain the required shape and accuracy. Therefore, a set of molds (upper and lower molds) must be matched, the material is placed between them, and the machine applies pressure to deform it. The reaction force caused by the force applied to the material during processing is absorbed by the punch machine body.
