Description

Technical Field

[0001] The utility model relates to the technical field of cemented carbide anvil processing, in particular to a processing base for cemented carbide anvils. Background Art

[0002] Since synthetic diamond was successfully developed by General Electric Company of the United States in 1954, the synthetic diamond industry has developed vigorously. Subsequently, the cemented carbide anvil, which is indispensable for synthesizing diamond, has also been developed and popularized. The anvil is a key consumable in the synthesis of superhard materials. The quality of the anvil determines the quality of diamond synthesis. At the same time, the processing efficiency of the anvil also determines the price of the anvil and the production cost of diamond.

[0003] When the anvil machine processes the anvil in the rough grinding nine-face process, it is necessary to replace the processing base according to different sizes and models of the anvil. At present, the processing bases for anvil are divided into three types according to the size of the anvil fixture, namely, a small processing base for small-sized anvils with D103 - D185, a processing base for medium-sized anvils with D190 - D210, and a processing base for large-sized anvil machine tools with D220 - D240. When processing large, medium, and small-sized anvils, it is necessary to replace these three processing bases back and forth on the processing machine. Since the base is heavy, hoisting operations are required, and the back-and-forth replacement is extremely troublesome, resulting in low production and processing efficiency and excessive labor intensity for workers. Summary of the Utility Model

The large inclined surface support surface and the side of the large inclined surface positioning and processing groove I close to the high-position support portion are in the same plane, and the small inclined surface support surface, the side of the small inclined surface positioning and processing groove I close to the high-position support portion, and the side of the small inclined surface positioning and processing groove II close to the high-position support portion are in the same plane.

[0006] Further, the cross-sections of the small inclined surface positioning and processing groove I, the small inclined surface positioning and processing groove II, the large inclined surface positioning and processing groove I, and the large inclined surface positioning and processing groove II are all V-shaped.

[0010] Further, when the bottom of the anvil is placed on the plane of the small inclined surface support surface, one small inclined surface of the anvil is horizontal; when the bottom of the anvil is placed on the plane of the large inclined surface support surface, one large inclined surface of the anvil is horizontal.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By providing a detachable positioning plate, the processing requirements of all models of cemented carbide anvils from D103 to D240 are met.
