Blanking device for production of pressure sensor diaphragms

Abstract

The invention belongs to the field of diaphragm production devices, and particularly relates to a blanking device for production of pressure sensor diaphragms. The blanking device comprises a workbench, the workbench is provided with supports, the supports are fixedly connected with a motor, an output shaft of the motor is movably connected with a blanking device body through a rotating part, andthe blanking device body comprises a lifting table, a blanking part and a pressing part. The lifting table is connected with the supports in a sliding manner, the pressing part is connected with the lifting table in a sliding manner, the workbench is provided with a punched hole, the blanking part and the punched hole are cooperatively arranged, and the punched hole is rotationally connected witha grinding sleeve. According to the blanking device for production of the pressure sensor diaphragms, excessive punching force in the machining process of the blanking device is avoided, the deformation amount of a metal wafer in the punching process of a blanking tool is reduced, the blanking quality of the metal wafer is improved, meanwhile, burrs on the edge of the metal wafer can be ground inthe blanking machining process of the device, the machining efficiency of the diaphragms is improved, and the blanking device is suitable for being popularized.

Description

technical field [0001] The invention belongs to the field of diaphragm production devices, in particular to a punching device for pressure sensor diaphragm production. Background technique [0002] A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. Pressure sensors are usually composed of pressure sensitive elements and signal processing units. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. The diaphragm is a circular membrane-shaped elastic sensitive element in the pressure sensitive element, which directly affects the sensing accuracy of the pressure sensor to a certain extent. It also urgently needs to be improved. [0003] In the prior art, in the actual processing process of the punching device for pressure sensor diaphragm productio...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the actual processing process of the punching device for pressure sensor diaphragm production, due to the excessive punching force, it is easy to cause stamping deformation on the edge of the metal disc, which increases the labor intensity of the subsequent processing of the staff, and at the same time, the device has a single function and only realizes The blanking work of the metal disc cannot grind the burrs on the edge of the disc to a certain extent, which reduces the resource utilization of the equipment, reduces the production efficiency of the diaphragm, and reduces the economic benefits
