A punching die

Abstract

The invention relates to a blanking die, which includes a lower die, a mounting frame, a connecting cylinder, an upper die seat, a motor, a rotating frame, a cutting device and a punching device. The rear end of the lower die is equipped with a mounting frame, and the mounting frame The upper end of the upper die base is connected with the upper die base through the connecting cylinder, a motor is installed inside the upper die base, a rotating frame is installed on the output shaft of the motor, a cutting device is installed at the right end of the rotating frame, and a punching device is installed at the lower end of the rotating frame. The invention can solve the problem that when punching a thin steel plate, the upper die is usually used to directly punch and blank the thin steel plate, but because the thickness of the thin steel plate is relatively thin, the edge of the punched round hole may be under the action of a relatively large impact force. Deformation occurs, resulting in wavy edges of round holes. When punching round holes with different apertures, it is necessary to replace the corresponding punching dies. The replacement is more troublesome, and punching dies of different specifications require standing and regular maintenance.

Description

technical field [0001] The invention relates to the field of punching dies, in particular to a punching die. Background technique [0002] Blanking die is an indispensable process equipment in stamping production. It is mainly used for blanking and punching of various plates. The working part of the die is the cutting edge of the convex and concave dies. The main task of the punching die is to separate the materials. , when punching a thin steel plate, the upper die is usually used to punch and cut the thin steel plate. However, due to the thinner thickness of the thin steel plate, some situations may be encountered during punching: [0003] 1. When punching thin steel plates, the upper mold is usually used to directly punch and blank the thin steel plates. However, due to the thinner steel plates, the edge of the punched round hole may be deformed under the action of a large impact force. As a result, the edge of the round hole is wavy, which affects the quality of the pro...
