Abstract

The invention relates to a metal material machining technology and manufacturing method, in particular to a manufacturing method for nickel composite 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 composite boards; carrying out penetrant flaw detection; carrying out ultrasonic detection; polishing and cleaning the die; carrying out earlier stage processing of blanks; carrying out heating through a natural gas furnace; carrying out stamping forming, wherein three-time forming is adopted for the forming technology; carrying out spinning forming; cutting grooves; carrying out acid dipping; carrying out polishing; carrying out penetrant flaw detection and ultrasonic 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 metal material processing technology, in particular to a manufacturing method of a nickel composite plate head. Background technique [0002] Nickel clad plate is an excellent engineering structure material, with its usage expanding 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 during cold forming of the nickel composite plate, it is difficult to form and process. It is easy to cause problems such as tearing during forming, resulting in scrapping. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, thereby providing a method for manufacturing a nickel clad plate head, the stamping process is stable, the deformation is uniform and smooth, the determined thermal proce...
