The ball joint pin is one of the important security parts on the automobile. It has to withstand huge friction during the working process. In order to meet its working performance requirements, we usually use a medium frequency induction heating machine for quenching heat treatment. As we all know, most of the heat treatment of workpieces requires quenching inductors to complete. Today, Zhengzhou Gou's technical staff will tell you about the axis form inductor used when ball joint pins are quenched with a 200kw medium frequency induction heating machine.
Since the 1970s, inspired by the longitudinal heating and overall induction quenching technology of rectangular inductors for half shafts and other parts, several major domestic manufacturers such as FAW and Second Automobile Works have successively researched and successfully developed axial wire full profiling and quenching surface rotation heating and overall quenching technologies.
Compared with the medium-frequency simultaneous heating and quenching inductor, the axial wire full profiling inductor has the advantages of simple production of the inductor, convenient adjustment, and the good effect of obtaining a completely profiling distributed hardened layer.
The new type of inductor breaks through several induction hardening restricted areas of ball pin parts: namely, the lower part of the edge of the hemisphere and the rounded corner of the journal. When using a medium frequency quenching inductor, it is easy to overheat or overheat during induction heating. Burning; the rectangular longitudinal heating inductor has extremely low heating efficiency during induction heating, the heating rate is very slow, and the two parts are very close to each other. To make the two parts reach the quenching temperature at the same time without a large temperature difference, the structure of the inductor It must be very sophisticated. The most valuable thing is the grade depth distribution of the spherical hardened layer, which is almost similar to carburizing. The use of axis profiling induction quenching to achieve uniform distribution of the hardened layer of ball stud parts is a major advancement in the field of induction quenching.
The axis imitation form inductor solves the various defects of the ball stud's previous quenching and has great advantages in the heat treatment of the ball stud. Zhengzhou Gou's is not only a specialized manufacturer of induction heating equipment, but is also quite familiar with the manufacturing of various inductors. If you want to know more about inductor manufacturing and information on workpiece heat treatment, you can call us for consultation.
