A reaction block of superhigh pressure equipment for processing a large-size cutting tool, belongs to a material processing equipment manufacturing technology field. The reaction block is composed of a block body, a flake heater, a metal adhesive sheet, a formed cushion block and a mica insulator, wherein the block body is an oblate body, the medium part is a round through hole, the flake heater is transversally arranged in the through hole, the metal adhesive sheet is fixed on the surface of the flake heater, the formed cushion block is arranged in the through hole, and an opening part of the formed cushion block has the mica insulator. When processed, the cutting tool is formed from a metal powder material by placing a superhard material powder into the formed cushion block, sealing by the mica insulator, sending the reaction block into the high temperature and high pressure equipment for processing. Because the superhard material powder and the metal adhesive sheet are simultaneously affected by the high temperature and high pressure equipment and the flake heater, the superhard material powder and the metal adhesive are fully mixed to form the cutting tool; and because the block is the oblate body, the block body can bear big pressure. The equipment provided by the invention can process the large-size cutting tool with a various shapes, and the processed cutting tool has good quality.
Description
technical field [0001] The invention belongs to the technical field of material processing equipment manufacturing, and relates to cutting tool processing equipment. Background technique [0002] The reaction block of the existing ultra-high pressure equipment for processing cutting tools is generally made of cylindrical or square cylindrical ceramic materials. When processing cutting tools, metal powder materials and adhesives are added to the cylinder, and the reaction block is sent to high-temperature and high-pressure equipment. During processing, the metal powder material is formed into a cutting tool. This kind of reaction block only has the cutting tool of fixed shape, and the shape of the cutting tool depends on the shape in the reaction block tube, and the size of the cutting tool is also limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reaction block of ultra-high pressure equipment for proce...
