Problems solved by technology
[0006] In the first process, the production and processing time of a single piece is long, and the utilization rate of the part material is low
[0007] In the second process, multiple stamping equipment is required, and multiple stamping operators and debuggers cooperate to complete it. There are many processes, low production efficiency, unstable product quality, low degree of automation, and large production safety hazards. It is only suitable for small batch production

A forming process of an electrode for a discharge tube and a mold designed for implementing the process, the process includes: a blanking process; The die, the forming die, the male punch and the female punch form a closed cavity to extrude the formed part so that all parts of the part meet the process requirements except for the size of the inner hole; the punching process. The invention also provides a molding die designed for implementing the process. The invention solves the problems of the forming process and the structure of the forming mold for the automatic mass production of electrodes for discharge tubes, and ensures the external dimensions, surface roughness, coaxiality of the outer circle of the step to the inner hole, and the parallelism of the two step surfaces. Compared with the existing technology, it has the advantages of simple process, reasonable mold structure, convenient maintenance, safe operation, reliable work, good product quality and high production efficiency.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and relates to the manufacture of forgings or pressings. In particular, it relates to a forming process of an electrode for a discharge tube, and a mold designed for implementing the process. Background technique [0002] The electrode for the discharge tube is a part used on the ceramic gas discharge tube. Its two stepped surfaces are used as ceramic sealing reference surfaces, and the inner hole has a discharge function. It is an important core part of the ceramic gas discharge tube. At present, the domestic ceramic gas discharge tube electrode processing process mainly has the following types: [0003] 1. Automatic lathe turning: ① flat end face; ② outer circle turning; ③ step surface turning; ④ top hole; ⑤ center hole drilling; [0004] 2. Multi-process stamping forming: ① cutting; ② one-time shaping; ③ two-time shaping; ④ three-time shaping; ⑤ four-time shaping; [0005] There are fol...
