Description

Technical Field

[0001] The invention specifically relates to an aluminum shell with a stepped hole for welding an explosion-proof valve tool. Background Art

[0002] Aluminum shell usually refers to a shell or outer cover made of aluminum material, which is widely used in electronic products, mechanical equipment and other industrial fields. In order to facilitate pressure relief, the shell made of aluminum shell needs to be processed with a step hole on the aluminum shell, and then an explosion-proof valve plate is welded on the step hole. When the electronic products inside the aluminum shell are accidentally damaged and emit a large gas pressure, the higher pressure inside the aluminum shell is released through the explosion-proof valve plate.

[0003] When punching steps on the existing aluminum shell, the aluminum shell is placed or removed from the workbench manually, the aluminum shell is loaded and unloaded, and then the stamping cylinder drives a single punching tool to move up and down, so as to punch the aluminum shell. Manual loading and unloading is time-consuming and labor-intensive, and the operation is labor-intensive. In addition, a single punching tool cannot meet the requirements of simultaneously performing rough punching, step punching, and fine punching of through holes on the aluminum shell, and the processing efficiency is slow. For this reason, we propose an aluminum shell punching step hole for welding explosion-proof valve tooling. Summary of the invention
