Description

Technical Field

[0001] The utility model relates to the field of automobiles, and particularly relates to a stamping die for automobile chassis parts. Background Art

[0002] At present, the Chinese utility model with the publication number CN217369974U discloses a stamping die for automobile chassis parts, including a die table. A top plate is movably connected above the die table. The output end of the stepping motor is provided with a rotating shaft that penetrates through both side surfaces of the waste box. Both sides of the waste box are provided with rotating shafts sleeved on the outer surface of the rotating shaft. Both sides of the bottom end of the collection box are fixedly installed with arc blocks that cooperate with the convex blocks. By setting the compression springs in the stamping grooves on the upper surface of the die table, after the stamping block finishes stamping, the top block can be lifted, and the stamped die can be pushed out of the stamping groove by the way, which is convenient for scraping when driving the scraping component. When the die is scraped into the interior of the collection box by the scraping component above the waste box, the stepping motor is driven, so that the rotating shaft rotates to drive the convex block, and the arc blocks on both sides of the collection box can be knocked in a swinging state, so that the collection box makes an up-and-down shaking and screening effect under the elastic connection of the elastic connection component.

[0003] For the existing stamping die, the production efficiency is low. The precision requirements for automobile chassis parts are high, with structural negative angles and difficult demolding. In the industry, single-process and adjusting the product angle for stamping production are mostly adopted. Therefore, the production efficiency is low, and too many processes are difficult to ensure the product stability. As a result, the production is complex, the quality is unstable, the efficiency is low, and the cost is high. It is also not convenient to replace the inductor. Generally, the inductor is installed and fixed by threads. When replacing the inductor, tools are needed to disassemble and assemble the inductor. The disassembly and assembly process is relatively cumbersome, increasing the workload and reducing the replacement efficiency. To solve the above problems, we propose a stamping die for automobile chassis parts. Summary of the Utility Model
