The manufacturing process of large and small heads
Seamless size head making
Small head (reduced pipe) is a pipe fitting used for pipe calibers. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing. Stamping can also be used for some specifications of reducing pipe.
Reduction/expansion forming
The reducing forming process of the small head is to put the tube blank with the same diameter as the big end of the big head into the forming die, and press the tube blank along the axial direction to make the metal move along the die cavity and shrink forming. According to the size of the reducing pipe, it can be divided into one pressing forming or multiple pressing forming.
Forming by stamping
In addition to using steel pipe as raw material to produce the size of the head, some specifications of the size of the head can also be produced by steel stamping process. The shape of the die used for drawing is designed according to the size of the inner surface of the head, and the steel plate after blanking is pressed and drawn by the die.
