Abstract

The invention discloses an automatic center adjusting polycrystalline die of a high-speed vertical enamelling machine, which relates to the field of high-speed vertical enamelling machine painting technology. A die core raw material is manufactured into a die core, electrolytic copper, zinc, cobalt, molybdenum, nickel, chromium and tin are uniformly mixed to obtain sintering powder, a die holder is then fixed through a graphite die sleeve, the die core is placed in the die holder, sintering powder is later added between the die holder and the die core, the die core is fixed to the center of the die holder in a hot pressing sintering mode through the powder metallurgy technology, and the automatic center adjusting polycrystalline die of the high-speed vertical enamelling machine is obtained. The die core is prepared from the diamond micro-powder, the intermediate 3 and the temperature-resistant filler, and under the synergistic effect of the intermediate 3 and the temperature-resistant filler, the high-temperature stability of the polycrystalline diamond prepared from the diamond micro-powder is effectively improved, so that flaws in the die core are avoided, the mechanical property of the die core is ensured, and the product quality is ensured; and the service life of the high-speed vertical enameling machine automatic adjustment center polycrystalline die is prolonged.

Description

technical field [0001] The invention relates to the field of high-speed vertical enamelling machine painting technology, in particular to a high-speed vertical enamelling machine automatic adjustment center polycrystalline mold. Background technique [0002] The enameled wire painting process involves high-speed vertical machine painting molds. At present, high-speed vertical machines use tungsten carbide mold cores. The disadvantages are: difficulty in changing gauges, poor finish, frequent wire jams during production, large amount of wire waste, and parallel paint films. The temperature is poor, the production efficiency of workers is low, time-consuming and power-consuming; [0003] In order to improve production efficiency, reduce energy consumption, and improve product quality, by setting the polycrystalline diamond core body and placing the polycrystalline diamond core body between the sintered body and the mold base, it can effectively ensure that the paint film on th...
