The design principle of Stamping Press is to convert the circular motion into linear motion, drive the flywheel by the output of the main motor, drive the gear, crankshaft (or eccentric gear), connecting rod and so on through the clutch to achieve the linear motion of the slider, and the motion from the main motor to the connecting rod is circular motion. There should be a transfer point of circular and linear motion between the connecting rod and the slider. There are roughly two kinds of mechanisms in the design, one is ball type and the other is pin type (cylinder type). The circular motion is converted into the linear motion of the slider through this mechanism. The punch applies pressure to the material, so that the plastic deformation, and obtain the required shape and accuracy, so it must be matched with a group of die (divided into upper die and lower die), the material is placed in the middle, by the machine to exert pressure, make its deformation, processing force on the material caused by the reaction force, by the punch mechanical body absorbed.
