Abstract

PURPOSE: To improve productivity by extruding while pulling near the stop mark of an extruded section material with a clamping mechanism provided with a cutting device and thereby cutting the section material during extrusion.
CONSTITUTION: A billet 3 in a container 2 is extruded by a stem 1 and formed to a section material 4. At this time, extrusion forming is made while pulling the tip of the section holding it by a self-trveling clamping mechanism 5 provided with a cutting device 6. When the billet 3 in the container 2 is extruded completely, extrusion is stopped and next billet 3 is charged. Meantime, the clamping mechanism 5 provided with the cutting mechanism 6 returns near the extrusion port and start the next extrusion. The extruded section 4 is carried by a runout table 7. When a stop mark S appears on the surface of the section 4, the clamping mechanism 5 is actuated to clamp near the stop mark. Then, the section 4 is pulled and cut during extrusion by the cutting device 6. Cut section 4 is transferred to a straightening device by quick sending of the runout table.
