Technical Field

The invention relates to a die for producing a stainless steel wire, which is used for drawing the stainless steel wire and belongs to the technical field of metal product pressure processing.

Background

The stainless steel mainly uses chromium as an additive, and due to the property of the stainless steel, the hardenability is obviously improved when the stainless steel wire is subjected to cold drawing, an original hard alloy die and a die inner hole type structure are unreasonable, and a die inner hole is easily damaged when the stainless steel wire is drawn, so that the produced stainless steel wire has a rough surface, does not reach the quality standard, is low in production efficiency, and cannot meet the requirement of cold drawing processing of the stainless steel wire.

Disclosure of Invention

The invention aims to solve the technical problems that an original hard alloy material die and an inner hole type structure of the die are unreasonable, and an inner hole of the die is easily damaged when a stainless steel wire is drawn, so that the produced stainless steel wire has a rough surface, does not reach the standard quality, is low in production efficiency, and cannot meet the requirement of cold drawing processing of the stainless steel wire.

In order to solve the technical problems, the invention adopts the following technical scheme:

a die for producing stainless steel wires is composed of an inlet cone 1, a lubricating cone 2, a working cone 3, a sizing belt 4 and an outlet cone 5, and is in a hollow cylinder shape;

In the figure: 1-inlet cone, 2-lubricating cone, 3-working cone, 4-bearing, 5-outlet cone, H-total height of die and d-bearing aperture.

Detailed Description

As shown in figure 1, the die for producing the stainless steel wire consists of an inlet cone 1, a lubricating cone 2, a working cone 3, a bearing 4 and an outlet cone 5, wherein the shape of the die is a hollow cylinder;

the total height of the die is marked H and the diameter of the sizing hole is marked d.

The implementation steps of the invention are as follows:

1. the mould is made of artificial diamond, and the hollow inner wall of the mould is ground and polished.

2. The die is used for cold drawing the stainless steel wire with the diameter of 2.0 mm-6.0 mm, namely d is the diameter of 2.0 mm-6.0 mm.

3. The hollow part of the die sequentially comprises an inlet cone 1, a lubricating cone 2, a working cone 3, a calibrating strap 4 and an outlet cone 5 from top to bottom.

The structural parameters of each part of the five regions are as follows:

1) entry cone 1

The steel wire can enter the working cone 3 smoothly, the surface coating can not be scratched by the edge of the die hole, the angle is 90 degrees, and the height is 0.2 multiplied by Hmm.

2) Lubricating cone 2

To accumulate the lubricant, a dense and uniform lubricating die was formed on the surface of the steel wire, the angle of which was 60 degrees and the height of which was 0.5 XH mm.

3) Working cone 3

In order to ensure a deformation with a reduced circular section of the wire and to improve the performance of the wire, the angle is 20 °.

4) Calibration band 4

The sizing belt 4 is too long, so that the friction force is increased, the temperature of the die is increased, the stainless steel wire is bonded on the inner wall of the die, the steel wire cannot be drawn, and the height of the stainless steel wire is set to be 0.1 xd mm for reducing the friction.

5) Outlet cone 5

The steel wire outlet is convenient to avoid scratch, the heat dissipation effect is good, the angle is 90 degrees, and the height is 0.2 multiplied by H mm.

According to the invention, the proper die material is selected, the structural parameters of the die for cold drawing pressure processing are designed, and the problems of rapid damage to the inner hole of the die and rough surface of the steel wire are solved, so that the steel wire with qualified quality is achieved, and the production efficiency is greatly improved.
