The copper wire drawing machine is a machine that uses the ductility of the copper wire to reduce its diameter through the compression of die to achieve the desired wire diameter. According to the number of drawing heads at one time, it can be divided into single-head copper wire drawing machine, double-head copper wire drawing machine and multi-head copper wire drawing machine; according to the size of the incoming and outgoing wires, it can be divided into copper large puller, copper middle puller, copper small puller, copper fine puller and copper micro puller. This blog introduces a double-head copper drawing machine——LHD-450 / 13-2 high-speed copper wire drawing machine.
High-speed copper wire drawing machine Type LHD-450/13-2 or called rod breakdown machine works to draw Φ8mm pure copper rod into Φ1.3mm~Φ3.5mm wire simultaneously. The drawing capstans are arranged in a line that are able to work continuously with drawing speed; and also wire can be continuous annealed; and speed of mechanical parts and electrical control can match with each other. It is easy to operate, easy to change dies quickly. This machine has features of easy and convenient operation, high efficiency and good quality of product.
