Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of quenching processing, and particularly relates to an adjustable induction quenching system for a linear guide rail and a quenching method. BACKGROUND

[0002] Quenching is an important processing technology for improving the mechanical properties of workpieces. As one of quenching technologies, induction quenching uses electromagnetic induction principle to generate eddy current in the workpiece to heat the workpiece.

[0003] The linear guide rail is an important functional component on a machine tool and is used for movement positioning and guiding of the machine tool. The contact surface of the guide rail surface and the rolling component bears a large pressure in the use process, and thus the contact surface is required to have high hardness. Since the guide rail is a high-precision product and has high heavy load capacity, the guide rail has high requirements for the parallelism and flatness precision of installation. In order to ensure that the linear guide rail has good comprehensive mechanical properties and installation precision, the induction quenching method is the most ideal heat treatment method.

[0004] In the induction quenching process, due to the skin effect and proximity effect of the induction current, the side surface of the linear guide rail close to the inner surface of the inductor is more easily heated to a high temperature, and the side surface of the linear guide rail far from the inner surface of the inductor has a low temperature, thereby causing the temperature, hardened layer and mechanical properties of the two side surfaces to be uneven, resulting in the linear guide rail being bent and deformed along the guide rail axis direction due to the different heating temperatures and hardened layer depths of the two side surfaces, and affecting the quenching quality, shape precision and use effect of the linear guide rail.

[0005] The inductor may have position and shape errors in the machining process, and a certain position deviation may occur in the process of fixing the inductor on the machine tool slide. The machining and fixing deviation will affect the distance between the inductor and the two side surfaces of the linear guide rail, causing the distance from the two side surfaces of the linear guide rail to the inner surface of the inductor to be inconsistent, and finally causing the linear guide rail to be bent and deformed in the induction quenching process. At present, the induction quenching bending deformation of the linear guide rail is one of the main problems that trouble the industry.

[0006] Therefore, an induction quenching system capable of adjusting the position and angle between the inductor and the workpiece to be heat treated is needed to ensure the quenching quality of the linear guide rail. SUMMARY
