Embodiment
[0020] To strengthen the circular saw blade with a thickness of 16mm and a diameter of Φ2100mm for cutting H-shaped steel, the steps are as follows:
[0021] (1) Deformation detection of saw blades entering the site;
[0022] (2) Press figure 1 As shown, install the saw blade to be processed on the spindle of the machine tool, and adjust the swing to less than 1mm;
[0023] (3) Adopt broadband integral lens, H=20mm;
[0024] (4) Apply black light-absorbing paint to the teeth, and then wipe off the tooth tip paint;
[0025] (5) The light spot irradiates the circular saw blade radially, and the rotation direction of the main shaft is counterclockwise (such as figure 1 Arrow), where the lens angle α=45. , power N=2900W, outer circle speed V=800mm / min;
[0026] (7) Process quality monitoring, observe whether the beam irradiated surface is slightly melted, whether the non-irradiated surface (front) is gray-white quenching trace, and adjust the power and speed in time.
