Abstract
PURPOSE:To uniformly cool whole of an extruded metal through a quencher, by installing a memory circuit for making the speed of a puller, after a discard generated by the extrusion press work is cut off, equal to the speed of the puller before the discard is cut off. CONSTITUTION:A billet 16 is extruded by a pressure plate 14 and a pressure stem 15, and the front end of the extruded metal 17 is chucked by a clamper 2 at a fully withdrawn position of a puller 1. The puller 1 then draws the extruded metal 17 at a constant speed proportionally synchronous with the speed of extrusion press work; at the same time, a quencher 4 cools the extruded metal 17, and the drawing speed is detected by a detector 32 whose output is memorized by a memory circuit 31. When the extrusion press work is finished, a driver 23 of the puller 1 is stopped and the cooling water supply to the quencher 4 is stopped; then a shearing device cuts off a discard of the extruded metal 17. After this cutting work, the speed value stored in the circuit 31 is given as a command signal to a sequence logic part 27 for switching so as to automatically control the driver 23 through an amplifier-control circuit 28 by a power control 29, and then, the puller 1 draws the extruded metal 17.
