Problems solved by technology
[0003] The purpose of the present invention is to solve the unreasonable structure of the original cemented carbide mold and the inner hole structure of the mold, which is easy to damage the inner hole of the mold when drawing the stainless steel wire, thus resulting in the rough surface of the produced stainless steel wire, the quality is not up to standard, and the production efficiency is reduced. Low, can not meet the technical problems of cold drawing of stainless steel wire

Embodiment Construction
[0018] like figure 1 As shown, a mold for stainless steel wire production is composed of an inlet cone 1, a lubrication cone 2, a working cone 3, a sizing belt 4 and an outlet cone 5; the shape is a hollow cylinder;
[0019] The total height of the mold is marked as H; the hole diameter of the sizing belt is marked as d.
[0020] The implementation steps of the present invention are as follows:
[0021] 1. The mold is made of artificial diamond, and the hollow inner wall is ground and polished.
[0022] 2. The mold is used for cold drawing stainless steel wire with a diameter of 2.0mm to 6.0mm, that is, d is 2.0mm to 6.0mm in diameter.
[0023] 3. From top to bottom, the hollow of the mold is divided into five areas: the entrance cone 1, the lubrication cone 2, the working cone 3, the sizing belt 4 and the exit cone 5.
[0024] The structural parameters of each part of five regions of the present invention are as follows:
[0025] 1) Inlet cone 1
[0026] It is convenient...

A die for stainless steel wire production consists 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 the shape of a hollow cylinder;the die is made of artificial diamond, and the inner hole wall of the die is ground and polished; the angle of the inlet cone (1) is 90 degrees, and the height of the inlet cone (1) is 20% of the total height of the die; the angle of the lubricating cone (2) is 60 degrees, and the height of the lubricating cone (2) is 50% of the total height of the die; the angle of the working cone (3) is 20 degrees; the height of the sizing belt (4) is 10% of the aperture of the sizing belt; the angle of the outlet cone (5) is 90 degrees, and the height of the outlet cone (5) is 20% of the total height of the mold; and the die is used for cold drawing of stainless steel wires with the diameter ranging from 2.0 mm to 6.0 mm. According to the die for production, the inner hole of the die cannot be damagedin the stainless steel wire cold-drawing process, the surface of the produced stainless steel wire is smooth, the quality reaches the standard by 100%, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to a mold for producing stainless steel wires, which is used for drawing stainless steel wires and belongs to the technical field of pressure processing of metal products. Background technique [0002] Stainless steel mainly uses chromium as an additive. Due to the properties of stainless steel, the hardenability increases significantly when cold drawing stainless steel wire. The original cemented carbide mold and the inner hole structure of the mold are unreasonable, and it is easy to draw stainless steel wire. Damage the inner hole of the mold, resulting in the rough surface of the produced stainless steel wire, the quality is not up to standard, the production efficiency is low, and it cannot meet the cold drawing process of stainless steel wire. Contents of the invention [0003] The purpose of the present invention is to solve the unreasonable structure of the original cemented carbide mold and the inner hole structure of t...
