Description

Surface strengthening treatment equipment Technical Field The utility model relates to the technical field of surface strengthening, in particular to surface strengthening treatment equipment. Background With the continuous development of industrial technology, the improvement of the metal surface performance becomes an important direction for improving the service life, the wear resistance and the reliability of equipment. Surface strengthening technology, especially heat treatment technology or surface coating, is widely used to improve the surface hardness, wear resistance and corrosion resistance of metallic materials. However, the conventional technology has a certain limitation, and particularly, when dealing with certain high-demand roll shaft products, the effect is not ideal. In order to prolong the service life of the roll shaft workpiece, the hardness and wear resistance of the roll shaft workpiece are often improved by the traditional technologies such as heat treatment, surface coating, ultrasonic rolling, laser cladding and the like. However, the heat treatment has problems of a single hardness distribution, stress concentration, and increased brittleness, and the depth of the reinforced layer is limited. The surface coating technology has the defects of poor coating adhesion, limited thickness, poor coating uniformity and the like, and the treatment process can cause environmental pollution. Although the ultrasonic rolling technology can introduce a residual compressive stress layer (the depth can reach more than 3 mm) on the metal surface layer, the strengthening layer is thinner and has insufficient uniformity. Laser cladding can provide a deeper surface strengthening layer and excellent wear resistance, but is relatively high in cost, low in precision, prone to early spalling due to stress concentration, and complex in operation.
