Wire feed and traction system of wet wire drawing machine

Abstract

The invention discloses a wire feed and traction system of a wet wire drawing machine. The system comprises a metal wire wheel, a first drawing die, a second drawing die, ... , an N-1-th drawing die, an N-th drawing die, and a natural air cooling traction wheel mechanism. The first drawing die, the second drawing die, ... , and the N-1-th drawing die are disposed on a mould support, and the N-th drawing die is arranged on a position adjustable die holder. Metal wire raw materials are winded on the metal wire wheel, and successively pass through wire penetrating apertures of the first drawing die, the second drawing die, ... , the N-1-th drawing die, and the N-th drawing die to form a cutting wire finished product, wherein the drawing die are parallel to each other and arranged coaxially, and aperture diameters of wire penetrating apertures are reduced step by step. The cutting wire finished product is winded on a traction disc of the natural air cooling traction wheel to be packed up.The invention solves the problem of mould loss caused by overheating during wire penetration, so as to increase service life of equipment and reduce processing costs of cutting wires.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular to a wire threading traction mechanism of a water tank wire drawing machine. Background technique [0002] The water tank wire drawing machine is currently widely used for drawing fine-gauge metal wires. At present, due to the generally low wire drawing speed, the automatic control technology is not perfect, and the production efficiency is low. Axle steel wires, etc., cannot be used in the production line for cutting wires - because the quality requirements of cutting wires are high, the diameter tolerance is within ±0.003mm, and the ellipticity tolerance is within ±0.001mm. [0003] The common drawing process in the wire drawing machine is to pass the metal wire raw material through the drawing die to be squeezed and rubbed to become thinner, and the cutting wire after passing through a drawing die enters the next drawing die with a smaller diameter, repeating Af...
