Patent ES-417865-A1 (ES)
Title: Combined drawing and straightening machine for metallic tubes or rods
IPC: B21C3/02
Filed: 1973-08-13
Abstract: Machine for simultaneous reduction and straightening of metallic tubes or rods has a reducing die which is mounted in the frame downstream of a guide for workpieces and upstream of a ring-shaped straightening tool whose axis orbits about the axis of the opening in the die. The outlet end of the internal surface surrounding the opening in the die tapers counter to the direction of lengthwise movement of workpieces through the die. The guide insures that the workpieces cannot be flexed upstream of the throat portion of the internal surface of the die, and a second guide can be provided downstream of the straightening tool to confine the flexing of the workpieces to the region between the throat portion of the internal surface of the die and the second guide. The tool is mounted in a spherical bearing which is installed in the eccentric bore of a sleeve driven by a pulley to rotate about the axis of the die whereby the tool orbits the axis of its passage about the axis of the opening in the die.
