Packing of concentric reduce
The steel reducer (diameter pipe) is a pipe diameter for the pipe. The forming process usually used for the reduction of diameter, diameter expansion or diameter expansion plus diameter suppression, for some specifications of the different diameter pipe can also be used for stamping.
a. Reducing / expanding forming
Reducing the size of the head forming process is the size of the first large-end diameter equal to the tube into the forming mold, by pressing along the axial direction of the tube, the metal along the mold cavity movement and shrinkage forming. According to the diameter of reducing pipe size, divided into a press molding or multiple press forming.
In addition to the use of steel as the raw material to produce the size of the head, the size of some of the size of the head can also be used steel sheet metal stamping process for the production. The shape of the die used for drawing refers to the size of the inner surface of the head and the size of the die, and the blanked steel plate is stamped and stretched with a die.
