[0002] The pressure gauge usually adopts an internal card seal structure consisting of a shell, liquid contact components, transmission mechanism, etc. It is a special measuring instrument widely used in industrial equipment. The case is one of the most important components. The quality of the case production is directly related to the performance and reliability of the pressure gauge, so a case stamping device is required.

[0003] In the Chinese authorization announcement number CN207373085U, a device for disassembling the case of a pressure gauge is disclosed, including a base, two connecting rods, a pressure cover, a support frame and a pressure rod. The two connecting rods are vertically arranged on the base, and the support frame is laterally fixed on the two connecting rods. The support frame is provided with a threaded hole, and the pressure rod is a threaded rod. The pressure rod is connected to the support frame through the threaded hole. A recess is provided in the middle of the base. When disassembling the cover of the pressure gauge, the pressure gauge is placed on the recess of the base between the two connecting rods, the pressure cover is placed on the pressure gauge, and the pressure rod is rotated to squeeze the pressure cover. The cover of the pressure gauge is disassembled, which solves the problem of damage to the dial.

At the same time, some waste materials will be generated during the stamping process of the watch case. If they are not collected and processed, they are likely to be scattered everywhere and pollute the surrounding environment. If not handled in time, it will affect the subsequent reprocessing operations. Summary of the invention
