【Summary】 There are many types of explosion-proof tools, which can be used in a special environment and have excellent performance. However, there is not only one kind of material for this tool, but also many different types of materials, which are described in detail below. Copper alloy: Copper alloy explosion-proof tools can be used in many kinds of explosive gas places. In the ordinary production process, the hardness of copper alloy materials after treatment is a little higher than that of beryllium bronze materials, and also close to the hardness of steel tool products. Aluminum bronze: aluminum bronze is mainly divided into two categories, one of which is that when the content of aluminum does not exceed 9.4%, the metallography is used as a dendrite α Phase solid solution, the other is when the Al content is 1.8% - 9.4%, its structure is α+β 1+ α+γ 2。 This material has good thermal conductivity, because most of the heat generated when other objects collide with each other is absorbed by the tools and dissipated. The particles after grinding have little heat, which cannot lead to the explosion of air and combustible mixture. Beryllium bronze: Beryllium bronze is mainly a steel base metal with beryllium as the basic alloy element. Its content of beryllium ranges from 1% to 2.5%, and it has good trace elements such as cobalt and magnesium. Hot die forging process flow of explosion-proof tools: first, the forging drawing shall be drawn according to the explosion-proof tool drawing. Step 2: Determine the forging die process and auxiliary process according to the technical requirements and testing requirements of forgings. The auxiliary process usually includes removing the burrs of the workpiece edge extension, removing the flash, correcting the wrench parallelism, etc., and determining the size between processes. The third step is to determine the good heating method and heating specification according to the process, and determine the mold lubrication and cooling methods;. The fourth step is to determine the size, quality and allowable tolerance of the blank workpiece. Step 5: Determine the forging cooling method and specification. The sixth step is to determine the heat treatment method of forgings and the method of removing oxide skin on the surface of forgings. The seventh step is to select the forging equipment according to the forging size and die size. Step 8: Carry out inspection according to the technical requirements and inspection requirements of forgings.
