Embodiment Construction

[0017] see figure 1 , a manufacturing process of a pneumatic joint core, the steel billet raw material is made into a round material, and then the round material is subjected to phosphate surface treatment, and then the rough round material is subjected to spheroidizing annealing, phosphate film treatment, Fine drawing and sizing treatment, and finally the forming process of the pneumatic joint core in the cold heading forming machine, which specifically includes the following steps:

[0018] (1) Automatically cut the disc round material after precision drawing and sizing into a single pneumatic joint core blank 1 by the cold heading machine;

[0019] (2) The pneumatic joint core blank 1 is clamped by a mechanical fixture, and sent to the No. 1 die opening of the cold extrusion die, and the pneumatic joint core blank is pushed into the die by the punch of the No. 1 die, because The inner wall at the bottom of the die has a chamfer, and under the extrusion of the punching tool...

Abstract

The invention discloses a process for producing a pneumatic joint core. The process comprises the following steps of: producing raw materials of billet steel into round disc stock, then carrying out phosphate surface treatment on the round disc stock, then respectively carrying out spheroidizing, bonderizing, and fine drawing and sizing on the round disc stock after rough drawing, and finally forming the pneumatic joint core in a cold heading forming machine. The process realizes one-time forming with the cold heading machine, improves the productivity and the quality of the pneumatic joint core, saves raw materials, and reduces the production cost.

Description

technical field [0001] The invention relates to the field of manufacturing technology of a pneumatic joint core. Background technique [0002] The pneumatic joint core is an important part of the quick-change joint of the hose. It is used to seal the quick-change joint when the quick-change joint is transferred, so that the guided material does not leak when the joint is replaced, saves materials, and prevents the guided material from polluting the environment. . Its characteristics: corrosion resistance, high and low temperature resistance (-196 ° C ~ +420 ° C), light weight, small size, easy to use, good sealing. [0003] At present, the domestic production of this product mostly adopts the processing methods of material cutting, car repair, and fine cleaning. The comprehensive performance of its process equipment and products cannot meet the requirements of domestic and foreign markets. Its production not only wastes materials, but also has complicated procedures and dif...
