Problems solved by technology
Since the smallest tower wheel cannot be too small, and the largest tower wheel cannot be too large (the design is too large and does not meet the requirements of the mechanical structure), so the mechanical speed ratio Q can only be reduced (that is, D n / D n-1 ) value, according to the principle of constant volume in the drawing of metal materials, there is slippage between the material and the tower wheel during the drawing process, and the slippage is large if the speed-up ratio is small, and the frictional heat generated by the slippage is superfluous Power loss, and accelerated wear of the cone wheel

Abstract
The present invention is nine-mold copper wire drawbench set and aims at providing one wire drawbench set with proper drawing slide force, not reduced mechanical speed ratio, low power consumption and long service life of cone pulley. The nine-mold copper wire drawbench set includes a overhead unwinding wheel, wire inlet sensor, wire outlet sensor, main wire drawing unit, wire separating wheel, wire unloading unit, iron frame, rotary bench, main motor, hydraulic station and electric control box. It features the main wire drawing unit including four sets of parallel driving cone pulleys and one speed defining wheel, each of the driving cone pulley set includes two sheets mounted in the front end of the main shaft, and transmission gears with matched teeth number are installed in the back end of the main shaft. The present invention is used in drawing copper rod into copper wire.
Description
technical field [0001] The invention relates to wire drawing equipment, in particular to a nine-mode copper wire drawing unit. Suitable for drawing copper rods into copper wires. Background technique [0002] The copper material is smelted, formed and rolled, generally to a copper rod with a diameter of 8.0mm, and then drawn from a copper rod with a diameter of 8.0mm to a copper wire with a diameter of 2.5-3.0mm. To complete the drawing from the copper rod to the copper wire, it is necessary Rely on wire drawing machine to complete. Those skilled in the art know that during the drawing process of copper wire, the relationship between the drawn elongation K and the inherent mechanical speed ratio Q of the wire drawing machine should be determined within a certain range, generally K / Q=1.02 -1.08, this is the sliding rate of drawing; however, the requirements for the wire drawing machine in terms of mechanical structure are: the diameter of the minimum cone wheel cannot be to...
