Steel wire tip drawing technology and apparatus

Abstract

The invention discloses a steel wire drawing technique and device, comprising that 1, clamping and drawing the front of the steel wire which needs to pass through mould and drawn, 2, heating the steel wire, 3, forcing the clamped steel wire, to extend and crack the steel wire, removing the broken waste steel wire to obtain the mould-through steel wire with sharp end. The invention can improve working efficiency and improve plasticity.

Description

technical field [0001] The invention relates to a steel wire tipping process and device. Background technique [0002] In the wire drawing of metal products, the steel wire needs to be processed into a sharp point before the steel wire is drawn, and then it can be passed into the wire drawing die. At present, steel wire sharpening is generally done through grinding wheel sharpening, manual drawing method or curved roller sharpening. Among them, the grinding wheel sharpening and manual drawing method are all manual operations, resulting in large wire loss, poor work efficiency, and uncontrollable roundness. Phase transformation occurs, and the product quality cannot be controlled. In addition, the surface of the tip of the steel wire is rough, forming irregular water chestnuts, and there are scratches on the working area and sizing area of ​​the wire drawing die, which directly reduces the service life of the die. Compared with the above two methods, curved roll pointing has...

AI Technical Summary

Problems solved by technology

Because it uses the cold rolling process, the cooling and hardening inside the metal rapidly forms when the tip is rolled, which makes it difficult to pass through the die. In severe cases, the steel wire often breaks, resulting in the scrapping loss of the drawing die
