Embodiment Construction

[0021] exist figure 1 , a diamond wire drawing die is shown in longitudinal section. The wire drawing die jacket 1 and the wire drawing die 2 are assembled together by cold pressing or hot pressing, and the wire drawing die 2 has a hole 3, which is composed of the entrance area 4, the lubrication area 5, the working area 6, The sizing area 7 and the outlet area 8 are composed.

[0022] exist figure 2 In, the method of mechanical grinding of diamond wire drawing die is shown in the form of longitudinal sectional view. Wherein the number 9 is a grinding needle, the number 10 is a grinding powder, and the number 11 is a grinding additive. During the grinding process, grinding needles 9 of different specifications should be selected according to the different shapes and sizes of the processing areas. The selection of grinding powder and grinding additives should be selected according to different mechanical grinding. When coarsely grinding, grinding powder 10 can select No. ...

Abstract

A drawing diamond die is prepared through choosing die blank, inlaying it in external jacket, perforating to form hole, coar grinding, fine grinding, accurate grinding and polishing.

Description

【Technical field】 [0001] The invention relates to the field of wire drawing die manufacturing in the cable industry, in particular to a method for manufacturing a diamond wire drawing die. 【Background technique】 [0002] The wire drawing die is a necessary die for drawing metal wires from thick wire blanks with irregular sizes and shapes into fine wires with uniform size and meeting people's production or living requirements. Its main part is a mold core in the center, and the center of the mold core is processed with a small hole with a certain geometry and size and a certain surface roughness. After passing through this small hole or a series of small holes, the rough rough wire becomes the finished filament. Copper wires, aluminum wires, stainless steel wires used in our daily life and production, and tungsten wires used in incandescent bulbs are all drawn through wire drawing dies. [0003] A Chinese utility model patent authorization announcement number is CN-2565557Y...
