Description

Technical Field

[0001] The invention relates to the technical field of wire material manufacturing, and in particular to a multifunctional wire material hot drawing die. Background Art

[0002] With the development of science and technology, welding technology has experienced a development process from manual operation to automation and intelligence. With the development of welding technology, more types of welding wires have appeared. In order to improve production efficiency, continuous wires are widely used in the fields of welding and arc additives. The forming methods of continuous wires can be divided into hot drawing and cold drawing according to different temperatures. Hot drawing is mainly used for some materials with high hardness and poor plasticity, while cold drawing is used for materials with good plasticity and toughness at room temperature. For the forming quality of wires, the drawing die is the key, especially the hot drawing forming of wires. During the drawing process, the wire is heated and softened and then formed by the die. Its temperature will directly affect the working state of the die. If the heat dissipation effect of the die is poor, the die temperature will be too high and the die surface will be oxidized, thus affecting the service life of the die. In addition, overheating of the die may cause the high temperature performance of the die to decrease, wear to increase, and the die surface to deform or even crack, affecting the surface quality and dimensional accuracy of the die. Therefore, it is very important to control the temperature of the wire drawing die to ensure its normal operation and extend its service life.

[0003] Before drawing the wire, the wire head is first polished to make its diameter smaller than the die diameter, and the wire is drawn through perforation. During the wire drawing process, metal debris and lubricating materials generated by the die have a certain impact on the air and threaten personal safety. After the wire passes through the die hole, the surface debris of the wire is cleaned to prevent the debris from affecting the surface quality of the wire during subsequent drawing. Summary of the invention

[0004] Based on the above technical problems, the present invention provides a multifunctional wire hot drawing die to solve the problems that metal debris and lubricating materials generated by the die during the wire drawing process have a certain impact on the air and threaten personal safety.

[0012] Furthermore, the drying device is a heating induction coil.

[0013] Furthermore, the grinding device includes a bearing ball 10, a telescopic shaft 11 and a grinding wheel 12, the telescopic shaft 11 is connected to the inner ring of the bearing, and the telescopic shaft 11 and the grinding wheel 12 rotate through the bearing ball 10; the grinding wheel 12 is connected to the telescopic shaft 11 and rotates 360 degrees in a circle; the telescopic shaft 11 is freely retractable to achieve grinding of wires of different diameters; a fixing clamp 9 is installed before and after the grinding wheel 12, which plays a role in fixing the wire when the wire is ground, and by grinding the wire head to make its diameter smaller than the mold diameter, the wire is pulled out by perforating.
