There are various types of drawing dies, and common ones include multi-roll drawing machine, single-roll drawing machine, lead ring drawing machine, etc. Its main feature is that it can change steel and other metals into regular-shaped metal rods or tubes without changing their cross-sectional area, and it is widely used in the field of metal processing.
[0003] In the field of metal processing, drawing process is an important processing method, which is used to reduce the cross-sectional area and increase the length of metal raw materials through the hole type of die to achieve the desired size and shape. However, the material of traditional drawing die is prone to excessive wear and deformation due to high temperature generated during material drawing when processing high-hardness or high-wear-resistance metals, resulting in short service life of the die and low processing efficiency. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a kind of hard alloy drawing die to solve the problem of excessive wear and deformation of the drawing die material in the background technology when processing high-hardness or high-wear-resistance metals due to high temperature generated during material drawing, resulting in short service life of the die and low processing efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: including drawing die body and cooling tank, the bottom of the cooling tank is fixedly installed with a mounting column, an internal thread mounting hole is formed in the bottom of the mounting column;
[0006] A drain pipe is fixedly installed through the lower end of the cooling tank, a T-shaped limit slip ring is fixedly installed on the inner wall of the upper end of the cooling tank, a limit slip buckle is movably connected to the outer side of the T-shaped limit slip ring, an installation table is fixedly installed on the outer end of the limit slip buckle, a drive motor is fixedly installed on the inner side of the installation table, a transmission gear is fixedly installed on the lower end transmission shaft part of the drive motor, a transmission gear ring is engaged with the inner side of the transmission gear, a connecting pipe is fixedly installed on both sides of the installation table, and a water jet head is fixedly installed on the opening of the lower end of the connecting pipe.
[0007] Preferably, the drawing die body adopts a monolithic structure and is made of hard alloy material, and the outer curved surface of the lower end of the drawing die body is rotatably connected to the inner bottom of the cooling tank through a rotating shaft.
[0008] Preferably, the number of mounting columns is several, and each is distributed in rotational symmetry at the bottom of the cooling tank.
[0009] Preferably, the number of T-shaped limiting sliding rings is two, and each is symmetrically distributed on the inner wall of the upper end of the cooling tank.
[0010] Preferably, the transmission gear ring is fixedly installed on the inner wall of the lower end of the cooling tank.
[0011] Preferably, the number of connecting pipes is two, and each is symmetrically distributed on both sides of the mounting table, and the upper end of the connecting pipe is communicated with the external cooling water supply pipeline through the connecting hose.
[0012] Preferably, the water spraying head is directed to the outer curved surface of the drawing die body.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] 1. When the external cooling water supply pipeline is opened, the cooling water in the internal cooling water supply pipeline of the external cooling water supply pipeline enters the internal connecting pipe through the connecting hose. When the cooling water enters the internal connecting pipe, the cooling water in the internal connecting pipe is sprayed to the outer curved surface of the drawing die body through the water spraying head. When the cooling water is sprayed to the outer curved surface of the drawing die body, the drawing die body can be cooled by the cooling water. At the same time, the cooling water flows into the bottom of the cooling tank. When the cooling water flows into the bottom of the cooling tank, the cooling water in the bottom of the cooling tank is concentrated and discharged through the drain pipe, so that the drawing die body is cooled, and the cooling water used for cooling is conveniently concentrated and discharged.
[0015] 2. When the driving motor is opened, the transmission gear is driven to rotate. When the transmission gear rotates, the driving force generated by the meshing connection between the inner side of the transmission gear and the transmission gear ring drives the mounting table to rotate along the inner wall of the cooling tank. When the mounting table rotates along the inner wall of the cooling tank, the limiting sliding buckle rotates along the outer end of the T-shaped limiting sliding ring, so that the limiting sliding buckle and the T-shaped limiting sliding ring limit the rotation of the mounting table. When the mounting table rotates along the inner wall of the cooling tank, the drain pipe and the water spraying head rotate along the inner wall of the cooling tank. When the water spraying head rotates along the inner wall of the cooling tank, the water spraying head uniformly sprays cooling water to the outer curved surface of the drawing die body to cool it. The high temperature generated by material drawing is avoided, and the problems of excessive wear and deformation are easily avoided, so that the service life of the die is short and the processing efficiency is low.
