Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and more specifically, to a stamping die for processing metal sheets. Background Art

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) during cold stamping processing, called a cold stamping die. During the use of a stamping die, corresponding accessories are required to assist to ensure the stability of the die during the stamping process.

[0003] In the related art, in order to solve the problem that most current stamping dies are fixed by bolts, the operation of replacing the die is too cumbersome, inconvenient to replace, and affects production efficiency, the patent with the publication number CN218134514U provides a hardware fitting for a stamping die. This hardware fitting for a stamping die can, through the mutual cooperation between a driving plate, a driving screw, a clamping screw, a fixing clamp, etc., replace different dies according to different production requirements, so as to fix dies of different models and sizes. When replacing the die, the die is released from fixation and then removed from the workbench; through the combined action of a pressure rod, a limiting block, a return spring, etc., the workpiece steel plate can be tightly fixed when pressed down, preventing displacement during stamping and resulting in incorrect stamping.

[0004] Although the above-mentioned prior art solution can, through the combined action of a pressure rod, a limiting block, a return spring, etc., tightly fix the workpiece steel plate when pressed down, preventing displacement during stamping and resulting in incorrect stamping, there are still the following defects: when the material is subjected to an impact force, some materials are prone to splashing, which will affect the personal safety of the staff. At the same time, it is not convenient to take out the formed material after stamping, thus reducing production efficiency.

[0005] In view of this, we propose a stamping die for processing metal sheets. Summary of the Utility Model

[0031] Embodiment 2

[0032] A stamping die for metal sheet processing proposed by the present utility model. Compared with Embodiment 1, please refer to Figures 2-6 , wedge block 302 is slidably installed between mounting box 301 through chute 303. One end of push rod 304 is fixedly installed with extrusion plate 305, and anti-slip lines are arranged on extrusion plate 305. A motor 206 is fixedly installed on the top of top plate 103. The output end of motor 206 is meshed with a bevel gear set 207. The bevel gear set 207 and rotating gear 204 are installed through a transmission belt 208. Under the action of the bevel gear set 207, the transmission belt 208 can drive the pulley on one side of the rotating gear 204 to rotate, so that the rotating gear 204 can rotate synchronously.
