Cut steel wire straightener

Abstract

The invention discloses a cut steel wire straightener which is used for greatly increasing the natural diameter of a cut steel wire and is capable of detecting unqualified source wires, which comprises a base plate, wherein the base plate is provided with a horizontally arranged straightening device and a vertically arranged straightening device, each straightening device comprises a backing plate, a row of fixed bearings is fixedly arranged on the backing plate, one side of the backing plate is provided with a sliding plate of which one end is inserted into the backing plate, the backing plate positioned at one side of the sliding plate is provided with a waist-shaped hole, one side of the backing plate is provided with a plurality of sliding bearings which are respectively fixed on the sliding plate, the fixed bearings and the sliding bearings are respectively provided with guide slots, the fixed bearings and the sliding bearings are staggered, a steel wire channel is formed betweenthe fixed bearing and the sliding bearing, the sliding plate positioned at the outer side of the backing plate is provided with a waist-shaped hole of the sliding plate, the backing plate is providedwith a fixed block, the fixed block is movably provided with an eccentric shaft, the eccentric shaft is provided with a poking rod, and one end of the eccentric shaft extends into the waist-shaped hole of the sliding plate. The invention is used in places for producing cut steel wires.

Description

technical field [0001] The invention relates to a straightener for fine steel wires, in particular to a straightener for cutting steel wires. Background technique [0002] In the process of drawing the source wire into the cutting steel wire, due to the different degrees of deviation between the direction of the cutting steel wire and the center of the mold, this deviation cannot be solved in the prior art, and the cutting steel wire is partially extruded and rubbed when passing through the die opening. , causing the cutting steel wire to spiral and bend regularly in a natural state after it comes out of the die, and the greater the above-mentioned deviation, the smaller the bending diameter of the cutting steel wire and the greater the stress. This small-diameter cutting steel wire is easy to produce messy wires, knots, breaks, etc. when cutting workpieces. If there are joints in the source wire, unsatisfactory heat treatment, or uneven copper plating, etc., it cannot be d...

[0002] In the process of drawing the source wire into the cutting steel wire, due to the different degrees of deviation between the direction of the cutting steel wire and the center of the mold, this deviation cannot be solved in the prior art, and the cutting steel wire is partially extruded and rubbed when passing through the die opening. , causing the cutting wire to spiral and bend regularly in the natural state after it comes out of the die, and the greater the above-mentioned deviation, the smaller the bending diameter of the cutting wire and the greater the stress

This kind of small-diameter cutting steel wire is easy to produce messy wires, knots, breakage, etc. when cutting workpieces.

If there are joints in the source wire, unsatisfactory heat treatment, or uneven copper plating, etc., it cannot be detected in the existing drawing process, which is especially prominent when the workpiece is subsequently cut, which will bring great harm to the user. big loss
