Description

Technical Field

[0001] The present application relates to the technical field of wire drawing machines, and in particular to a wire drawing die that facilitates heat dissipation. Background Art

[0002] A wire drawing die is a tool used during the processing of metal workpieces to force metal through the die under the action of external force, compress the metal cross-sectional area, and obtain the required cross-sectional shape and size. The core of the wire drawing die is generally made of natural diamond or artificial diamond and is used for the preparation of metal wires, such as copper wire, tungsten wire, etc. Therefore, wire drawing dies are used more frequently, and a wire drawing die with good performance is essential.

[0003] When the wire drawing die is in use, it is very easy to generate heat due to the friction of the metal, which in turn increases the overall temperature of the wire drawing die. At present, it is generally cooled by coolant, but there is a lack of a circulating cooling mechanism for the coolant, which leads to a poor cooling method for the wire drawing die. In addition, the cooling method is single and the wire drawing die cannot be cooled quickly. There are some shortcomings, so it needs to be improved. Utility Model Content

The wire drawing die body 1 is immersed in the water cooling groove 2, and the side wall of the water cooling groove 2 is sealed and connected with the outer ring of the wire drawing die body 1, and a water inlet 21 and a water outlet 22 are provided at the bottom of the water cooling groove 2; a radiator 3, a circular cavity 31 adapted to the outer diameter of the wire drawing die body 1 is provided at the center of the radiator 3, a limiting through hole 32 is provided on the side wall of the radiator 3, and a limiting card groove 11 corresponding to the limiting through hole 32 is provided on the outer wall of the wire drawing die body 1; a limiting rod 4, the limiting rod 4 passes through the limiting through hole 32 of the radiator 3 and is clamped in the limiting card groove 11 of the wire drawing die body 1, and a threaded hole 41 corresponding to the radiator 3 is provided on the side of the limiting rod 4, and the limiting rod 4 is fixed by a screw 5 passing through the threaded hole 41 of the radiator 3 and the limiting rod 4. The wire drawing die body 1 is immersed in the water cooling tank 2, and the two ends of the wire drawing die body 1 are sealed with the water cooling tank 2, so that the wire drawing die body 1 can be completely immersed in the water cooling tank 2 for cooling, and the coolant inside it is circulated through the water inlet 21 and the water outlet 22 in the cooling tank to improve the cooling effect. At the same time, a radiator 3 is installed on the outside of the wire drawing die body 1, and the radiator 3 is mounted on the wire drawing die body 1, and the limiting rod 4 penetrates the limiting through hole 32 on the radiator 3, and then the two are fixed by screws 5, so that the radiator 3 is stably fixed on the wire drawing die body 1, which is convenient for the disassembly and assembly of the radiator 3.
