Correction method of εργαλείο σβέσης μηχανής after high-frequency quenching deformation

1. Use deformation compensation technology: when the guide rail of the quenching machine tool is planed, the two ends of the bed are supported, and the middle is pressed downward, so that the bed is deformed downwardly. After processing, the pressure is relieved and the elastic deformation is restored, thereby The middle of the control rail is concave.

2. Vibration aging eliminates internal stress: The bed vibration aging is performed between the surface quenching step of the quenching machine guide rail and the subsequent grinding process. The vibration aging is to fix the exciter on the bed, and the excitation force causes the workpiece to resonate. , the alternating motion of the bed absorbs the vibration energy, so that the residual force is well released, which can improve the stability of the bed size.

3. Lifting the local connection stiffness of the bed and the guide rail of the quenching machine tool is also a very effective method to deal with the deformation of the quenching machine tool after quenching.
