Is the reoccupy after burning red mold suppression and become, or direct suppression and become?
Tungsten steel (carbide) has high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even under the temperature of 500 ℃ is basic remains the same, there are still very high hardness at 1000 ℃. Hard alloy is widely used as a material, such as turning, milling, planing tool, drilling, boring cutter, etc., used for cutting cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, can also be used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel and other hard processing material. Now new type of cemented carbide cutting speed is equal to the carbon steel hundreds of times.
1, the shear plate. With the shearing machine cut the plank into suitable width; 2, blanking pieces. In the press with the blanking die cutting out appropriate to the size of the wafer; 3, deep drawing. With the deep drawing die on hydraulic press or punch out blank, on the edge of straw hats; 4, trimming. With the trimming die at the edge of the punch on cut off part of straw; 5, piping. With special trimming machine or spinning machine to make the plate edge; 6, polishing 7, decontamination 8, inspection on packaging.
Sheet parts without burning red, can be directly. Stainless steel plate overall process is obtained
