A device and process for continuous induction heating of a conjugated cam piece

Abstract

The invention relates to a conjugation type device and process for continuous induction heating of a cam piece. According to the device and the process, variable speed rotation of a cam is realized; ahorizontal linear sliding table device is coordinated to accurately control the cam to do linear motion back and forth in the horizontal direction, so that the processing cost is reduced; the cam which does the reciprocating linear motion and rotates at the variable speed is controlled to be conjugated with an induction coil of a heating device, so that the induction coil of the heating device isenabled to move at a relatively equidistant constant linear speed along the contour of the cam, accurate control over the gap between the induction coil and the cam is realized, the defect that in the prior art, the gap between the induction coil and the cam cannot be changed in the cam heating process is overcome, the method greatly overcomes the defect, and in the cam heating process, gaps between the induction coils and the cams in different areas are different; and the uniform vortex generated by a transverse magnetic field on the contour of the cam, and the magnetism gathering and flow driving effect of a magnetizer are fully utilized so that the contour of the cam can be heated in an efficient and energy-saving manner.

Description

technical field [0001] The invention relates to a cam heat treatment device, in particular to a device and process for continuous induction heating of a conjugated cam piece. Background technique [0002] Cam is a more commonly used component in mechanical transmission. The cam mechanism realizes the transmission of the mechanism through high secondary friction, so during the manufacturing process of the cam, its surface needs to be quenched to ensure hardness and wear resistance. In the prior art, the induction hardening of the cam adopts ring-type and profiling inductors, and the ring-type quenching inductor is only suitable for small-sized cams, and the uniformity of the hardened layer of the cam is not ideal, resulting in excessive quenching depth on some surfaces. Large, the use of ring-type and profiling sensors can easily cause overheating at the tip of the cam, the depth of the hardened layer is deep, the transition zone of the cam is not easy to heat, the depth of ...

[0003] Patent No. 201120336124.9 discloses a cam profiling follow-up scanning induction hardening device, which uses a profiling rotating wheel and the outer circle of the workpiece to have a uniform linear velocity, so that all parts of the workpiece surface have the same quenching time during the induction hardening process, greatly improving Ensure that the depth of the hardened layer at the tip of the cam and the transition zone are basically the same, and ensure the uniformity of the depth of the hardened layer of the cam. However, it is necessary to make different quenching mechanisms for different cam mechanisms, which increases the cost, and it can only maintain heating. The distance is constant, but it is not guaranteed that the heating distance is different in the peach tip part and the transition zone
