Embodiment 1)
[0017] The specific steps of the laser repair process of the automobile mold of the present embodiment are as follows:
[0018] A. Treat the surface of the mold to be repaired, and inspect and analyze the mold.
[0019] Remove the dust, oil, rust, etc. on the surface; record the original use conditions, hardness and mechanical performance parameters of the mold; detect the size of each part of the mold, determine the wear part and its wear amount; remove the right angle of the wear part by grinding, and remove the wear part the fatigue layer and wash it.
[0020] B. Heat the mold at a low temperature, the heating temperature is 100°C, to remove the water vapor and oil gas on the surface of the mold base.
[0021] C. According to the inspection and analysis results of the mold, program the cavity of the worn part of the mold (programming can use the numerical control machining simulation system of Siemens), formulate the process parameters, first perform laser cladding on the ...
Embodiment 2)
[0027] The rest of the laser repair process of the automobile mold of the present embodiment is the same as that of Embodiment 1, except that:
[0028] The composition and weight percentage of the alloy powder used are C: 0.08%, Cr: 15%, B: 1.5%, Si: 1%, Mo: 0.5%, Mn: 8%, W: 6%, TiO 2 : 8%, the rest is Fe.
[0029] The average hardness of the surface of the automobile mold repaired by this process is 56.5HRC, and the surface hardness at the lowest hardness value of all testing points is 55.2HRC.
Embodiment 3)
[0031] The rest of the laser repair process of the automobile mold of the present embodiment is the same as that of Embodiment 1, except that:
[0032] The composition and weight percentage of the alloy powder used are C: 0.1%, Cr: 13%, B: 2.5%, Si: 2%, Mo: 1.2%, Mn: 12%, W: 12%, TiO 2 : 15%, the rest is Fe.
[0033] The average hardness of the surface of the automobile mold repaired by this process is 57.8HRC, and the surface hardness at the lowest hardness value of all testing points is 56.3HRC.
