Process for manufacturing pneumatic inner and outer tooth joint blank

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.

Description

technical field [0001] The invention relates to the technical field of manufacturing blanks of pneumatic inner and outer tooth joints. Background technique [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.
