Abstract

PURPOSE:To form uniform threads on a cylindrical work with a simple device by fitting and fixing the cylindrical work to a die having been inscribed with desired threads, and moving a pressing member while pressing the same to the work thereby transferring the threads of the revolving die to the work. CONSTITUTION:In forming threads to a cylindrical work such as pipe, the cylindrical work 8 is fitted onto a die 5 fixed to the revolving shaft of a gear box 1 and having been inscribed with desired threads and is fixed by means of a bolt 7. A pressing member 6 which is freely rotatively held to the end of a tool rest 3 mounted to a moving table 3a and is pressed in the vertical directions by a cylinder 4 is pressed to the work 8 along said threads and while the die 5 is being rotated, the pressing member 6 is moved by a screw shaft 2, whereby the threads of the die 5 are transferred to the work 8 and the threads are thus formed. This method does not require stringent mechanical accuracy or the like, is suited for the formation of the threads for which the evenness of shapes is required and is able to form threads on the inside surface of a pipe as well.
