Description

Technical field [0001] The invention relates to the technical field of heat treatment, in particular to a machine tool and process for flame quenching automatic heat treatment of shaft parts. Background technique [0002] The camshaft is a key component in a piston engine. The main body is a cylindrical rod with approximately the same length as the cylinder group. There are several cams on it to drive the valve and control the opening and closing of the valve. The camshaft in the engine has a high speed and needs to withstand a large torque, but also needs to withstand periodic shock loads. The contact stress between the cam and the tappet is very high, and the relative sliding speed is also very high, so the wear of the cam working surface is more serious. In view of this situation, the camshaft journal and cam working surface should have higher dimensional accuracy, smaller surface roughness and sufficient rigidity, as well as higher wear resistance and good lubrication.
