They are widely used in many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipelines, etc. Pressure sensors are usually composed of pressure sensitive elements and signal processing units.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: when packaging the pressure sensor, a corrugated diaphragm is usually used for welding. In the subsequent production operation, if the diaphragm is accidentally touched, the diaphragm waveform is likely to be damaged, resulting in the product being scrapped.

[0004] To this end, we propose a device for punching diaphragm waveforms using a contoured structure to solve the above problems. Utility Model Content

The method of using a contoured body to punch diaphragm corrugations avoids the occurrence of damage to the flat diaphragm waveform during the production process to a great extent. At the same time, the double-step contoured body structure is adopted, which plays a double buffering and protective role for the flat diaphragm, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Multiple stamping bodies are respectively matched with multiple stainless steel tube shells, an upper corrugation is provided at the bottom of the stamping body, and a lower corrugation matched with the upper corrugation is provided at the top of the stainless steel tube shell. The stainless steel tube shell adopts a double-step contoured body structure, in which the upper corrugation and the lower corrugation cooperate to stamp the flat diaphragm, and welding points are provided on both sides of the lower corrugation on the stainless steel tube shell.

[0010] As a preferred embodiment, protruding plates are welded at the four corners of the base, and columns are welded on the four protruding plates, and the tops of the four columns are welded to the fixed top plate, so that the fixed top plate and the structure thereon remain stable.

[0011] As a preferred embodiment, the conveying rod is vertically arranged and connected to the bottom wall of the fixed top plate, so that the structure of the conveying rod remains stable.

[0012] As a preferred implementation scheme, ear plates are welded on the two opposite side walls of the lifting platform, upper sliding rods are respectively welded on the two ear plates, and sleeves are welded on both sides of the bottom wall of the fixed top plate, and the two upper sliding rods are respectively slid into the two sleeves; so that when the lifting platform is raised or lowered, the two upper sliding rods can be driven to slide in the two sleeves, making the lifting of the lifting platform more stable.

[0013] As a preferred embodiment, a fold margin portion is provided on both sides of the flat diaphragm, so that the flat diaphragm has a sufficient length when being punched to produce a waveform.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The device for punching diaphragm corrugations using a contoured body structure and the method of punching diaphragm corrugations using a contoured body greatly avoid the occurrence of flat diaphragm corrugations being damaged during the production process. At the same time, the double-step contoured body structure is adopted, which plays a double buffering and protective role for the flat diaphragm.
