Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts processing, specifically to a punch for automobile parts processing. BACKGROUND

[0002] Punches can be divided into mechanical punches and hydraulic punches according to driving force. Mechanical punches are driven by compressed air, while hydraulic punches are powered by liquid. Oil hydraulic punches are more commonly used in ordinary sheet metal stamping, while water hydraulic punches are more commonly used in giant machines or special machines.

[0003] The working principle of a punch is to drive a flywheel by a motor, convert the circular motion into the linear motion of a slide block through mechanisms such as a clutch, a gear, a crankshaft, and a connecting rod, thereby exerting pressure on the material to deform it to the desired shape and accuracy. Lubrication, correct installation of the die, stability of the compressed air pressure, and safety of the operation need to be paid attention to during use. When processing automobile parts, a punch is needed to process the automobile parts into the target shape.

[0004] A punch for mechanical processing according to application number 202022055705.7 is provided with a stepped plate, a protective plate, and an expansion plate, which can reduce noise during mechanical processing, prevent metal debris from bouncing around, improve the safety of operators, and reduce the incidence of occupational diseases. However, the device still has some defects.
