Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing equipment, and particularly relates to a quenching device for the sliding surface of a workpiece. Background Art

[0002] With the rapid development of industry, the requirements for the performance of parts are increasing day by day. As an important heat treatment process, surface induction quenching can significantly improve the performance of the part surface. Our company can completely achieve the quenching of the upper surface and the vertical surface of large workpieces by using a quenching inductor made by placing a magnetic conductor on a square copper tube. However, for the quenching of the sliding surface of large workpieces, due to the unreasonable placement of the magnetic conductor, the quenching of the sliding surface cannot be achieved. For the induction heating quenching of the upper plane of large workpieces, the concave magnetic conductor can be placed with the opening facing down on the conductive square tube of the inductor. However, for the quenching of the sliding surface of large workpieces, the concave magnetic conductor needs to be placed with the opening facing up under the conductive square tube of the inductor. In this way, the magnetic conductor will fall due to the action of gravity. If the magnetic conductor powder is adjusted into a paste with phosphoric acid and directly bonded to the inductor, it is not only time-consuming and laborious but also the effect is not ideal. If the concave magnetic conductor of the inductor is placed with the opening facing down on the conductive square tube, not only the induction heating effect will be reduced, but also the upper surface and the side surface of the magnetic conductor block the 45° water spray cooling port, and the function of quickly cooling the workpiece after induction heating of the sliding surface cannot be achieved, that is, the quenching of the sliding surface cannot be achieved.
