Embodiment Construction

[0018] see figure 1 , a manufacturing process of the outer casing rough blank, the raw material of the steel billet is made into a round material, and then the phosphate surface treatment is carried out on the round material, and then the rough-drawn round material is subjected to spheroidizing annealing and phosphate film treatment respectively , fine drawing and sizing treatment, and finally the forming process of the outer casing blank in the cold heading forming machine, which specifically includes the following steps:

[0019] (1) Automatically cut the disc round material after precise drawing and sizing into a single outer casing blank 1 in the cold heading machine;

[0020] (2), utilize mechanical fixture to clamp described outer casing blank, send the No. 1 die mouth of cold extrusion die, the outer casing blank is pushed into the die by the punching tool of No. 1 die, because There is an ejector pin on the top plug at the rear end of the die, and the inner wall at th...

Abstract

The invention discloses a process for manufacturing outer sleeve blanks, which is characterized by comprising the following steps: preparing billet raw materials into wire rod materials; then carrying out phosphate surface treatment on the wire rod materials; respectively carrying out shpheroidizing annealing, phosphating, fashioning and sizing processing on the wire rod materials subjected to roughing; and finally, completing the process of forming outer sleeve blanks in a cold heading forming machine. The process disclosed by the invention has the advantages that because the outer sleeve blanks are formed at one step by using a cold heading machine, the production efficiency and product quality of the outer sleeve 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 an outer tube blank. Background technique [0002] The outer sleeve blank is an important part of the cap gun. The cap gun replaces the traditional welding nut, and does not need tapping, welding, or internal thread tapping; It is widely used in the fastening field of manufacturing industries such as various metal sheets and pipes due to its shortcomings. At present, the domestic production of this product mostly adopts the processing methods of cutting materials and car repairing. 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, difficult processing and low efficiency Low, and the quality is not guaranteed accordingly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a m...
