Problems solved by technology

[0002] Pneumatic inner and outer tooth joint blanks are an important accessory on quick connectors, because quick connectors can be connected or disconnected without tools. Quick connectors are widely used in people's daily life. With the increasing demand for quick connectors , the market demand and quality of quick connector related parts and components have been greatly improved. At present, the domestic production of this product mostly adopts the processing methods of cutting materials and car repairs. The comprehensive performance of its process equipment and products cannot meet domestic and foreign requirements. According to the requirements of the market, its production not only wastes materials, but also has complicated procedures, difficult processing, low efficiency, and the quality cannot be guaranteed accordingly.

Embodiment Construction

[0018] see figure 1 , a manufacturing process of pneumatic inner and outer tooth joint rough blanks. The raw material of the steel billet is made into a round material, and then the round material is subjected to phosphate surface treatment, and then the rough drawn round material is subjected to spheroidizing annealing, phosphate Film treatment, fine drawing and sizing treatment, and finally the forming process of pneumatic inner and outer tooth joint blanks in the cold heading forming machine, which specifically includes the following steps:

[0019] (1) Automatically cut the disc round material after precision drawing and sizing into a single pneumatic inner and outer tooth joint blank 1 in the cold heading machine;

[0020] (2) Use mechanical fixtures to clamp the pneumatic internal and external tooth joint blanks to the No. 1 die opening of the cold extrusion die, and push the pneumatic internal and external tooth joint blanks into the concave by the punching tool of the ...

Abstract

The invention discloses a process for manufacturing a pneumatic inner and outer tooth joint blank. The process comprises the following steps of: making a round disc material from a steel blank raw material, performing phosphate surface treatment on the round disc material, performing spheroidizing annealing, phosphate coating treatment and fine extraction and diameter fixing treatment on the round disc material subjected to rough extraction, and finally performing a forming procedure of the pneumatic inner and outer tooth joint blank in a cold forming header. The forming procedure of the pneumatic inner and outer tooth joint blank comprises the specific steps of: breaking the material; forming and heading the material into a hexagonal shape with circular beads; turning the material, forming and heading a first location hole at the upper end and an inner chamfer at the lower end; translating the material and heading a first counter bore at the front end; heading the other end of the turned material into a hexagonal shape with inclination angles, and heading a second location hole; translating the material and heading a second counter bore at the front end; and removing residual scrap iron in a middle hole so as to manufacture the final blank. The cold header is used for forming at one time, so the production efficiency and the quality of the pneumatic inner and outer tooth joint blank are improved, the raw materials are saved, and the production cost is reduced.
