Description

Technical Field

[0001] The utility model relates to a quenching machine tool, in particular to a gantry walking type medium frequency quenching machine tool. Background Art

[0002] The bed of the machine tool is a large basic component with guide rails (mountain-shaped guide rails and flat guide rails) with high precision requirements. It is used to support and connect the various components of the machine tool and ensure that the components have accurate relative positions during operation. It mainly has the functions of vibration reduction, vibration resistance, and pressure resistance. It is the main part that supports the whole machine tool when it is working. However, the bed of the current quenching machine tool is fixed, and most of them are quenched by moving the workpiece or quenching parts set on one side of it, which leads to a large machine tool volume and a large area. At the same time, the selection of the moving speed of the machine tool during quenching is very important. Under certain conditions of other process parameters, the slower the moving speed, the deeper the hardened layer on the surface of the workpiece, but the production efficiency is reduced. If the moving speed is too fast, the surface hardness of the workpiece will be reduced. Therefore, the moving speed is generally controlled within the range of 1.2 to 3 mm / s. How to control the speed and ensure the smooth movement of the parts is an urgent need for improvement in the existing quenching machine tools. Utility Model Content
