Abstract

The invention relates to a metal material machining technology and manufacturing method, in particular to a manufacturing method for nickel board end sockets. The manufacturing method comprises the steps of designing a die; calculating the diameter of an upper die pressure head, the diameter of an outlet of a lower die pull ring, the gap between an upper die and a lower die and the circular bead of the lower die pull ring; splicing nickel boards; carrying out penetrant flaw detection; detecting the hardness; carrying out stress relief annealing processing on the nickel boards; polishing and cleaning the die; carrying out earlier stage processing of blanks; carrying out stamping forming, wherein three-time cold forming is adopted for the forming technology; cutting grooves; carrying out acid dipping; carrying out polishing; carrying out penetrant flaw detection; stacking the end sockets. By means of the method, the stamping process is stable, transformation is even and smooth, a determined hot working system is feasible, the technology parameters are reasonable, control over the dimension of workpieces is good, metal streamline distribution is reasonable, and performance is stable.

Description

technical field [0001] The invention relates to a manufacturing method of a metal material processing technology, in particular to a manufacturing method of a nickel plate head. Background technique [0002] Nickel plate is an excellent engineering structure material. With the expansion of its usage year by year, it is more and more used in the processing and manufacturing of various engineering structures and equipment. Due to the disadvantages of poor plastic deformation, easy cracking, and large resilience when forming nickel materials, it is difficult to form and process. Problems such as tearing during forming, resulting in scrap. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, so as to provide a method for manufacturing a nickel plate head. The stamping process is stable, the deformation is uniform and smooth, the determined heat treatment system is feasible, the process parameters are reasona...
