Problems solved by technology

Ordinary wire drawing dies have poor heat dissipation, and the forming temperature of the wire is relatively high. Once the temperature exceeds the standard, the brittleness of the formed wire is too large, and the wire is prone to breakage, which affects the normal drawing operation; at the same time, the mold core that is too high The temperature is also easy to aggravate the loss of the mold core, which affects the service life of the mold core and virtually increases the cost of wire production

Abstract

The invention discloses a wire drawing mould manufacturing method capable of implementing water cooling treatment. The manufacturing method comprises the following steps of: (a) manufacturing a steel sleeve mould blank; (b) machining a steel sleeve; (c) manufacturing a mould core; (d) assembling a wire drawing mould; (e) carrying out welding treatment; (f) carrying out the post processing of the wire drawing mould. The wire drawing mould manufacturing method capable of implementing the water cooling treatment, which is disclosed by the invention, is reasonable in procedure arrangement, easy and convenient to implement and moderate in cost. A mould core prepared according to the manufacturing method is high in accuracy and is stable in connection with the steel sleeve; a spiral groove structure inside the steel sleeve can be used together with an external water circulation system, so that the whole wire drawing mould is cooled, the forming temperature of a wire is effectively controlled, the phenomenon of wire fracture is prevented in a drawing process, and the processing quality and processing efficiency of the wire are enhanced.

Description

technical field [0001] The invention relates to a method for manufacturing a wire drawing die, in particular to a method for manufacturing a wire drawing die capable of implementing water cooling treatment, and belongs to the technical field of die manufacturing. Background technique [0002] The wire drawing die is a tool for drawing metal wire (rod) material. All wire drawing dies have a die hole in the center, the shape of the die hole can be round, square or octagonal. Metal shrinks in size and even changes shape as it is pulled through the die hole. The current drawing die is mainly composed of a steel sleeve and a mold core. The steel sleeve is usually made of stainless steel. The mold core can be made of hard alloy, alloy steel, natural diamond or artificial diamond. The two are permanent through interference fit or welding. Connection. [0003] Due to the large friction and vibration in the wire drawing production process, a large amount of heat will be generated ...
