Forming process of stainless steel hemispherical end socket

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0021] The forming process of a stainless steel hemispherical head provided by the invention comprises the following steps:

[0022] 1) Cut the circle: cut by the plasma cutting machine according to the specified blanking;

[0023] 2) Stamping: Stamping is carried out by a 2000-ton stamping machine equipped with a PHH1100R1100-8AB1100 die;

[0024] 3) Welding tooling: tooling for welding solid solution;

[0025] 4) Solid solution: heat treatment according to the solid solution temperature of stainless steel;

[0026] 5) Unloading tooling: remove the solid solution tooling;

[0027] 6) Pre-bevel: place the head on the bevel rotating platform, and use the MAX250 plasma torch to remove the bevel when unloading the tool;

[0028] 7) Pre-pickling: remove oxides produced on the surface of the head during heat treatment;

[0029] 8) Stamping and forming again
