Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, specifically to a stamping fixing device for automotive mold production. Background Technology

[0002] In the automobile manufacturing process, the stamping device for automobile molds is one of the key pieces of equipment. It is mainly used to stamp parts into the shape of automobile components. This stamping device usually consists of an upper module, a lower die groove, a stamping machine, and a control system. The shape and design of the upper module and the lower die groove are determined according to the parts to be produced. During the stamping process, the stamping part is placed between the upper module and the lower die groove, and then the stamping machine applies huge pressure to deform the stamping part and form the required shape. However, during the stamping process, the stamping part is subjected to a large impact force, which makes it easy for the stamping part to move, thus affecting the quality of automobile parts. Therefore, it is usually necessary to use a fixing device to clamp and fix the stamping part.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] Most existing fixing devices have relatively simple structures, and they are usually fixed by clamping the two sides of the stamped part. However, this fixing method has poor stability, and the stamped part still has the possibility of moving and springing up, which is not conducive to use. Summary of the Invention

[0029] The working principle of this utility model:

[0030] In use, the automotive stamping part is placed on top of the mounting base 1 and between the two first clamping blocks 9 and the two second clamping blocks 24. Then, the third servo motor 251 is started to drive the worm gear 252 to rotate, which in turn drives the third threaded rod 21 to rotate through the worm wheel 253. During the rotation of the third threaded rod 21, the two traction blocks 23 and the two second clamping blocks 24 will move relative to each other through the two third threaded sleeves 22, thereby clamping and fixing the front and rear sides of the stamping part. Then, the two first servo motors 131 are started to drive the two drive gears 132 to rotate, which in turn drives the two first threaded sleeves 11 to rotate through the two driven gears 133. During the rotation of the two first threaded sleeves 11, the two first clamping blocks 9 will move relative to each other through the two first threaded rods 12, thereby clamping and fixing the left and right sides of the stamping part.

[0031] Then, the two second servo motors 191 are activated to drive the two drive bevel gears 192 to rotate, which in turn drive the two second threaded rods 15 to rotate via the two driven bevel gears 193. During the rotation of the two second threaded rods 15, the two moving blocks 17 and the two pressing blocks 18 move downward via the two second threaded sleeves 16, thereby clamping and fixing the top left and right sides of the stamped part. By clamping and fixing the stamped part on the front and back sides, left and right sides, and top, the fixing effect is improved, and the movement and bounce are minimized, thus ensuring the smooth progress of the stamping operation. Finally, the two hydraulic cylinders 4 are activated to drive the module 5 to move downward, pressing the stamped part into the mold groove 6 to perform the stamping operation. This solves the problem that the existing fixing devices are mostly simple in structure, generally fixing the stamped part by clamping the two sides, but this fixing method has poor stability, and the stamped part still has the possibility of movement and bounce, which is not conducive to use.

[0032] Any aspects not described in detail in this specification are techniques well-known in the art.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
