Pointing process and device beneficial to drawing and die penetrating of steel wire

Abstract

The invention discloses a pointing process and device beneficial to drawing and die penetrating of a steel wire, and belongs to the technical field of drawing and die penetrating of steel wires in deep processing of wire rods. The pointing device comprises a rotary straightener, a fixed chuck, an electromagnetic induction heating pipe and a movable chuck which are sequentially arranged in the direction of the steel wire. The pointing process comprises the following steps of paying off and straightening, pressing the steel wire, heating the steel wire, breaking the steel wire, and drawing die penetrating. According to the pointing process and device beneficial to drawing and die penetrating of the steel wire, the steel wire is heated through the electromagnetic induction effect, the heating speed is high, and cleanliness and no pollution are achieved; the strength of the steel wire is greatly reduced after the steel wire is heated, when the end of the steel wire moves forwards at a low speed along a sliding rail along with the movable chuck driven by a lead screw, the heated steel wire can be evenly thinned and snapped only by means of small clamping force, and a steel wire conical head beneficial to drawing and die penetrating of the steel wire is rapidly, safely and stably formed; and the accidents of hurting people, hurting fingers, squeezing and the like due to the fact that a pointing machine is manually used for mechanical pointing are avoided, operation is easy, time is shortened and labor is saved, working efficiency is high, operation is stable, and use is safe.

Description

technical field [0001] The invention belongs to the technical field of steel wire drawing and piercing dies in deep processing of wire rods, and more specifically relates to a sharpening process and a sharpening device that are beneficial to steel wire drawing and piercing dies, and are especially suitable for thick-sized wire rods or large-diameter steel wires. The ends are pointed. Background technique [0002] During the drawing process, the wire rod or steel wire needs to be sharpened, that is, the end of the steel wire is rolled thin to facilitate die penetration. At present, the commonly used pointing machine adopts the method of mechanical rolling for pointing. The mechanical pointing has the following disadvantages: 1. The rolling time is long; 2. The steel wire needs to be rotated. It is very hard, and the operation is troublesome and laborious. At the same time, the sharp teeth of the roll are easy to hurt people during the rolling process, causing safety hazards ...
