Description

Technical Field

[0001] The utility model belongs to the technical field of anvil production auxiliary equipment, in particular to a convenient transfer fixture for a cemented carbide anvil. Background Art

[0002] In the superhard material synthesis industry, carbide anvils are key components in ultra-high-pressure, high-temperature devices used to synthesize artificial diamonds through the hydrostatic pressure method. During the production process, carbide anvils, from raw materials to blanks and then to finished products, require transfer between different processing equipment. This involves chamfering the anvils. For a detailed structure, see CN217453384U, which discloses a carbide anvil chamfering mechanism. Because the anvils are made of carbide and are therefore heavy, specific lifting equipment is required to assist in their transfer. This lifting equipment requires a carbide anvil transfer fixture.

[0003] Publication No. CN216425654U discloses a clamp for transporting a cemented carbide top hammer blank, comprising a first clamping arm and a second clamping arm rotatably hinged to each other, the first clamping arm being rotatably connected to a first connecting piece, the second clamping arm being rotatably connected to a second connecting piece, a screw being provided between the first connecting piece and the second connecting piece, and screwing the screw being used to drive the first clamping arm and the second clamping arm to rotate relative to each other through the first connecting piece and the second connecting piece to clamp or release the top hammer blank; after clamping, a lifting rod is passed through the connecting frame, and an operator transports the top hammer blank and the clamp as a whole by hand or by using a lifting device. In its technical solution, the transfer of the top hammer is achieved by passing the lifting rod through the connecting frame, which easily makes it difficult for the top hammer to be in a vertical state during the transfer and clamping process, making it difficult to place the conical portion of the top hammer on a special clamp for chamfering processing; in addition, when it is necessary to process the conical portion of the top hammer, it is difficult to flip the top hammer with this technical solution, and it is necessary to flip the top hammer blank manually or use other transfer clamps, which is difficult to meet people's needs.
