| titleOfInvention | A kind of processing method of high temperature resistant vehicle cladding element punch mould |
| abstract | The invention belongs to stamping die of automotive covering part processing technique fields, more particularly to a kind of processing method of high temperature resistant vehicle cladding element punch mould, the material of the stamping die is middle alloy tool steel, including greasy dirt cleaning, cast alloys layer, vapor deposition tungsten carbide film layer and nickel base alloy layer.The present invention has the advantage that compared with prior art selects suitable alloying component in the present invention, combine it effectively in middle alloy tool steel surface, then it is handled with cryogenic fluid, alloyed layer recrystallization, make alloy surface grain hardening, and it will appear partial pore, then its surface successively in corresponding vacuum condition and temperature under the conditions of vapor deposition tungsten carbide film layer and nickel base alloy layer, wherein tungsten carbide film layer can effectively fill the micropore of alloy surface, it is effectively combined with alloy-layer, improve bond strength, nickel base alloy layer has stronger corrosion-and high-temp-resistant ability, surface smoothness is high. |
