ABSTRACT:
A method for forming a pipe includes providing a tubular workpiece having an upper portion and a lower portion; forming a tapered hole in the inner wall of the upper portion of the workpiece and forming an annular shoulder on the outer wall of the upper portion of the workpiece synchronously by cold forging operation; forming a plurality of teeth on the outer wall of the lower portion of the workpiece by a turning-machining operation, thereby forming the pipe which includes the tapered hole, the annular shoulder, and the teeth; and finally reinforcing the pipe by carburizing treatment.
