Title:
METHOD AND MILL FOR DRAWING WIRE WITH ULTRA HIGH PRESSURE LUBRICATION
Document Type and Number:
Japanese Patent JP2532318
Kind Code:
B2
Abstract:

PURPOSE: To provide a wire drawing method and mill for executing drawing wire rod by supplying while pressurizing an ultra high pressure lubricant in between dies under plural dies system.
CONSTITUTION: Plural pieces of dies 2, 3 are arranged at a prescribed interval in a die holder 1 in an ultra high pressure lubricant wire drawing mill and the lubricant is supplied while pressurizing from a press-in hole 6 arranged at the downstream side in an intermediate chamber 5 and while relatively keeping this flow speed to drawing speed or more of the wire rod, the lubricant is made flow out of a flow-out hole 7 arranged at the up-stream side, and successively, after the lubricant is cleaned with a fine particle removing device 11, the lubricant is again pressurized and while circulatively supplying the lubricant into the intermediate chamber 5, the drawing work of the wire rod 4 is executed. The lubricant in the intermediate chamber is fluidized and by discharging impurity to out of the chamber, damage of a die and the wire rod and wire slendering and wire cutting are prevented, and further, by preventing overheating of the temp. of the lubricant, reduction of the drawing force of the wire rod in the ultra high pressure lubricating wire drawing and reducing effect of die wear are displayed.
