Hydrodynamic drawing process for multi-stage drawing machine of the laminated composite wire and hydro-dynamic drawing processing method of the laminated composite wire

摘要

(57) Abstract This invention is something regarding the method in order hydro-dynamic it draw wires to process the lamination compound wire rod with the forced feed lubrication type multi-stage wire drawing machine, before starting or restarting the multi-stage wire drawing machine, or, the direct of the wire drawing dies of each wire drawing step is high-level, the lamination compound wire rod where haidorosutateitsuku starting pressure is formed inside the wire drawing gap depending upon the suffering heating high pressure room which makes the lamination compound wire rod pass, operates the wire drawing lubricant where this high pressure room is introduced into the high pressure room, especially, possesses with the high intensity core and the soft sheathing with itself widely known manner the advance which is done alongside lubricantIt is possible to process to high quality at the hydro-dynamic pressure ratio which is formed inside the wire drawing gap during continual wire drawing in. In the device of attachment, with the pre- dies and the wire drawing dies, the suffering heating high pressure room which with these forms structural unit (3) to be provided, this high pressure room (3) to include the wire rod passage (7) also the cross direction lubricant passage (8), furthermore, liquid pressure operational pressure occurrence expedient (9) to be arranged desirably in the high pressure room (3), other lubricant supply expedient (11) through, the lubricant passage (8) as for the lubricant which is supplied, to be possible the wire rod passage (7) to press in beforehand by decisive possible pressure, the high pressure room (3)The heating system which is provided inside cooperating, it deteriorates to paste state, at the same time before the lamination compound wire rod penetrates into the particular wire drawing step, it surrounds this lamination compound wire rod.
