Description
Technical Field
The utility model belongs to the technical field of laser quenching, and particularly relates to a guide rail surface laser quenching device.
Background
Laser quenching is a quenching technique that heats the surface of a material to a point above the transformation point by using laser light, and as the material itself cools, austenite is transformed into martensite, thereby hardening the surface of the material. The obtained fused quenching structure is very compact, and has deeper hardening depth, higher hardness and better wear resistance compared with induction quenching and other modes.
The laser quenching has high power density and high cooling speed, does not need water or oil cooling medium, and is a clean and rapid quenching process. Compared with induction quenching, flame quenching and carburizing quenching processes, the laser quenching hardening layer is uniform, the hardness is high (generally higher than that of induction quenching by 1-3 HRC), the workpiece deformation is small, the depth of a heating layer and a heating track are easy to control, automation is easy to realize, corresponding induction coils are not required to be designed according to different part sizes like induction quenching, and the machining of large parts is not required to be limited by the size of a hearth in the process of chemical heat treatment such as carburizing quenching and the like, so that the traditional processes such as induction quenching, chemical heat treatment and the like are gradually replaced in many industrial fields. It is particularly important that the deformation of the workpiece before and after laser quenching is almost negligible, so that the method is particularly suitable for the surface treatment of parts with high precision requirements.
The laser quenching is used for processing the surface of the guide rail, the processing efficiency is high, the distortion is small, the hardness is generally improved by 15% -20%, the wear resistance is improved by 1-10 times, the residual compressive stress of about 4000MPa is generated on the quenched surface, and the surface strength and the fatigue resistance are obviously improved. However, because the guide rail has multiple surface angles and different shapes, the workpiece placement angle is often required to be adjusted by a special tool for manufacturing so as to achieve the maximum light spot power density, and meanwhile, the workpiece is required to be placed again after one surface is machined, which is time-consuming and labor-consuming.
