Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire drawing dies, and more specifically, to a high-precision non-coated microporous wire drawing die. Background Art
[0002] A wire drawing die refers to a die used for drawing metal wire rods, bars, tubes and other materials. A wire drawing die usually consists of a die core, a die sleeve and a fastening device, etc. The die core is the core part of the wire drawing die, and it has a hole with a specific shape inside, which is used to control the shape and size of the metal material. When drawing a metal wire with a special shape, when installing the die core, the direction of the die core needs to be particularly concerned. If the installation direction is incorrect, it will lead to a decline in the quality of the drawn product. In serious cases, the product will be scrapped, causing economic losses.
[0003] At present, the installation direction of the die core is usually controlled by using an asymmetric shape design and a size difference design. For example, the diameters at the front end and the rear end of the die core are inconsistent, or an arrow is designed on a certain surface of the die core, and the arrow points to a specific direction. When installing, the operator must install it in the direction indicated by the arrow to ensure the correct installation direction of the die core. However, this method will still lead to incorrect installation directions due to the negligence of the operator or the complexity of the operation.
[0004] Therefore, a high-precision non-coated microporous wire drawing die is proposed, which can specify the installation direction, improve the installation accuracy, reduce economic losses, and provide the function of ensuring the personal safety of the operator. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a high-precision non-coated microporous wire drawing die that can specify the installation direction, improve the installation accuracy, reduce economic losses, and ensure the personal safety of the operator.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A high-precision non-coated microporous wire drawing die, including a die shell assembly, and a die core assembly is inserted into the center of the die shell assembly; the die shell assembly includes a shell body, a die core hole is opened on one side of the shell body, a die core guiding hole is opened on one side of the shell body, a first guiding part is arranged on the outer wall of the shell body along the contours of the die core hole and the die core guiding hole, a second guiding part is arranged on the inner wall of the shell body along the contours of the die core hole and the die core guiding hole, a forming hole is opened at one end of the shell body away from the die core guiding hole; the die core assembly includes a die core body, and a die core guiding block is arranged at the top of the die core body.
[0008] By adopting the above technical solution, the die core holes and die core guiding holes on the outer shell body provide an installation environment for the die core assembly. The die core guiding holes can also ensure the direction of the die core assembly, preventing product rejection and economic losses caused by incorrect direction during the processing of special-shaped products. Moreover, the die core holes and die core guiding holes are set in a shape with a larger inner diameter and a smaller outer diameter, which can effectively prevent the die core assembly from falling off the die outer shell assembly.

[0011] By adopting the above technical solution, the first guiding portion prevents the fingers from being scratched when the operator touches the surface of the workpiece, or prevents the metal wire from being scratched when the metal wire is installed into the die core assembly, thus affecting the product quality. The forming hole provides a processing shape for the metal wire to be processed. The forming heat dissipation slope improves the heat dissipation capacity during wire drawing, reducing the problem of thermal deformation caused by overheating of the workpiece. Through the first forming guiding portion and the second forming guiding portion, on the one hand, it prevents the fingers from being scratched when the operator touches the surface of the workpiece, or prevents the metal wire from being scratched when the metal wire is installed. On the other hand, it also increases the contact area with the air and improves the heat dissipation capacity.

[0014] The present utility model is further configured such that: the die core installation guiding portion is arranged away from the first guiding portion, a die core forming hole is formed through the center of the die core body, and the die core forming hole is adapted to the shape of the forming hole.
[0015] By adopting the above technical solutions, the mold core guide block confirms the installation direction, preventing product rejection and economic losses caused by incorrect direction during the processing of special-shaped products.

The mold core installation guide part on the outer side of the mold core body and the mold core guide block improves the shape adaptability with the second guide part, facilitating installation. At the same time, when the operator installs the mold core assembly, it avoids touching the workpiece surface, which may easily cause finger scratches and personal injury accidents.
