Camshaft quenching inductor
Camshaft quenching inductor, camshaft induction heating coil custom
Camshaft quenching induction coil sensors generally fall into two types: copying sensors and sensors, copying sensor has a high requirement on the workpiece positioning accuracy, and in different planes of multiple CAM, induction coil, not continuous in turn into every quenching a CAM need to tear open outfit, more difficult to ensure that each joint induction coil, contact is good, the poor stability of product quality and production efficiency is low, general rarely used in mass production. The successful application of the circular inductor on the continuous quenching of the camshaft of a small engine in this part has been proved to be unsuitable by the previous production practices of several cooperative units. Is that the main problems of CAM peach pointed part and base circle by heating temperature difference is very big, in guarantee under the condition of base circle part meet the technical requirements, peach pointed part after quench hardening layer depth will be deep, can't reach the drawings, technical requirements, and easily causing cracking or CAM peach, pointed at the CAM lift appear the phenomenon such as soft belt, a qualified rate is not high.
