ABSTRACT:
Apparatus for automatically forming pointed ends for raw metal pipes such as aluminum pipes subject to a drawing process, the pointed end of the pipes being of a reduced diameter convenient for the drawing process. A transporting device moves each raw pipe, which is in alignment with an axis of a pipe inlet of a swaging machine for producing the pointed ends, to a position below the inlet. Each pipe is raised by a lifting device to a height of the pipe inlet so as to be chucked by a gripping device which moves forward to insert a leading end of the pipe into the inlet. The lifting device and the raw pipe are kept out of contact with each other while the leading end is being processed to form the pointed end at the inserted end in the swaging machine whereby efficiency and productivity are improved for the process.
