Function and application classification of wire drawing machine

The main function of wire drawing machine is to process copper wires into thin wires of various specifications. The equipment generally has the characteristics of impact load, large starting torque and low-speed full torque output. In the system, many sets of high-speed precision proportional linkage control are generally required, and the characteristics of the driving device require relatively high load.

According to different uses, it can be divided into metal wire drawing machine, plastic wire drawing machine and bamboo wood wire drawing machine. The purpose of metal wire drawing machine is to transport the wire rod or bar produced by steel manufacturers to metal product manufacturers such as standard parts through the drawing treatment of wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightening of wire rod or bar can meet the raw material treatment requirements required for the production of metal products such as standard parts; Plastic wire drawing machine is a kind of solid core, hollow round wire or flat wire produced from polyester, nylon, polyethylene, polypropylene, polyester chip and other raw materials for deep processing and drawing into fine wire. The plastic wire drawn by the equipment has the advantages of uniform thickness, smoothness, not easy to break and less energy consumption.

According to the internal control mode and structure, the wire drawing machine can be divided into water tank type, pulley type, linear type and so on. The water tank wire drawing machine belongs to sliding wire drawing, and the diameter of the finished wire drawing is between 0.1 ~ 1.2mm, which can be drawn in multiple passes; The working characteristics of the pulley wire drawing machine are non sliding wire drawing with torsion, and the diameter of the wire drawing finished product is between 0.5 ~ 4.5mm; The diameter range of linear wire drawing finished products is higher than the above two, which is between 0.5 ~ 7.0mm. There is no sliding or torsion during operation.

The wire drawing process of wire drawing machine is composed of setting out, water cooling, take-up and wire arrangement. In addition to water cooling, motors are required for other processes. With the continuous improvement of science and technology, DC drive and torque motor used in electrical system have been gradually replaced by AC frequency conversion technology, which has played a leading role in wire drawing machine equipment.
