Stamping production is mainly aimed at sheet metal. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extrusion can be carried out through the die, which is widely used in various fields. For example, we use switch sockets, cups, cupboards, dishes, computer cases, and even missile planes. Many accessories can be produced by punching machines through molds.
Introduction.
Transmission structure: the common punching machine is driven by a motor, which drives the crank slider to reciprocate up and down after being decelerated by one to two or three gear pairs. The hydraulic punch is a motor that drives the oil pump motor to pump hydraulic oil into high pressure, and the solenoid valve controls the oil cylinder to drive the slider to reciprocate up and down.
Lower point control: the lower point of ordinary punch is fixed, and the lower point of hydraulic punch can be adjusted by adjusting the position of switch. The speed of ordinary punch can be adjusted by speed regulation, while hydraulic punch is generally difficult to adjust.
