Processing method of hard alloy oval die head and device for achieving method

Abstract

The invention discloses a processing method of a hard alloy oval die head and a device for achieving the method. The processing method comprises the steps that a, proper grinding wheels are manufactured according to the size of the oval core head, a grinding wheel group is formed, and a coarse grinding wheel and a fine grinding wheel are respectively mounted at the two ends of a main shaft of a numerical control grinder; b, a workpiece which needs to be processed is mounted on a core rod; c, the grinder is started, a base of the grinder rotates to drive the workpiece, and the workpiece is moved to the coarse grinding wheel for coarse grinding and is moved to the fine grinding wheel for fine grinding according to different processing requirements; and d, a hard alloy oval die can be obtained through repeated coarse grinding and fine grinding. The device comprises a grinding wheel device and a rotating mounting base, wherein the grinding wheel device comprises a first grinding wheel and a second grinding wheel; the first grinding wheel and the second grinding wheel are mounted at the two ends of the main shaft; the rotating mounting base comprises a base, a supporting part and the core rod; the core rod is arranged on one side of the supporting part; and the base drives the workpiece to move between the first grinding wheel and the second grinding wheel by virtue of a rotating shaft.

Description

【Technical field】 [0001] The invention relates to a processing method of a cemented carbide elliptical tube core head and equipment for realizing the method. 【Background technique】 [0002] At present, the usual method of processing cemented carbide special-shaped molds is to use slow wire processing. The defects of this processing method are poor surface finish, low precision, and large processing limitations. In the copper pipe manufacturing industry, the precision and surface finish of the mold are required to be higher, and the angle range of the mold is large, and the mold that adopts slow wire processing cannot meet the requirements; figure 1 with figure 2 The shape shown. [0003] In order to overcome the above-mentioned problems, we have developed a method for processing a cemented carbide elliptical die tip and equipment for realizing the method. 【Content of invention】 [0004] The technical problem to be solved by the object of the present invention is to pro...
