Blanking die

Abstract

The invention relates to a blanking die which comprises a lower die, an installation frame, a connecting air cylinder, an upper die seat, a motor, a rotating frame, a cutting device and a blanking falling device. The installation frame is installed at the rear end of the lower die. The upper end of the installation frame is connected with the upper die seat through the connecting air cylinder. Themotor is installed in the upper die seat. An output shaft of the motor is provided with the rotating frame. The cutting device is installed at the right end of the rotating frame. The blanking falling device is installed at the lower end of the rotating frame. By means of the blanking die, the problems that that when steel sheet is punched, an upper die is usually used for directly punching and blanking the steel sheet, due to the fact that the thickness of the steel sheet is small, the edges of punched round holes are possibly deformed under the effect of large impact force, the edges of theround holes are in a wave shape consequently, corresponding blanking dies need to be replaced for punching of round holes with different hole diameters, replacing is troublesome, and the blanking dies with different specifications need to be prepared always and maintained regularly are solved.

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...

[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 product; when punching round holes with different apertures, it is necessary to replace the corresponding punching die, which is troublesome to replace, and punching dies of different specifications need to be kept and regularly maintain
