Inventor: UEDA SHOGO
IPC: B21C1/04
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To enable wire drawing for a good quality extra fine metal wire by setting an average value of a designed reduction of a wire inlet side smaller than the average value of a designed reduction of a finish wire side when a total designed reduction of a wire drawing device is divided into a wire inlet side and a wire finish side. SOLUTION: A wet type slip continuous wire drawing device main body 5 is arranged with dies D of >=10 pieces. A wire rod to be drawn passes a die D1 to be coiled to a coiling block C1 -1, further passing a die D2 to be coiled C2 -1. The wire W successively passes a die group D to be reduced for a finished wire Wf and then is coiled. Because a speed at a wire inlet side is slow, influence resulting from slip is reduced, in the case of a small designed reduction, a wire drawing reduction is not reduced in proportion thereto, wire drawing is done without reducing a total reduction, an increase of die wear and power consumption is suppressed.
