Steering knuckle king pin hardening by medium frequency induction hardening equipment

The steering knuckle king pin is one of the important parts of the steering mechanism of the front axle of the car. It is a safety part and one of the important parts to ensure the safe driving of the car. During work, the kingpin of the steering knuckle is subject to huge friction, so we usually require the kingpin of the steering knuckle to have high hardness, wear resistance and service life. Anyone who understands the heat treatment process knows that quenching is the best way to improve the hardness and wear resistance of the workpiece, and is the key factor to ensure the quality of the workpiece. Therefore, it is very important to choose a good quenching equipment. A few days ago, our customer purchased a medium frequency induction hardening equipment for quenching heat treatment of the kingpin of the steering knuckle.

The king pin of the steering knuckle is quenched and heat-treated by medium-frequency induction hardening equipment, and its inductor is a profiling sensor made according to the specifications of the king pin. This kind of inductor can make the quenching of the kingpin more uniform, and there will be no phenomenon that some parts cannot be quenched, which ensures the quenching effect of the kingpin. Even better, the equipment can be used in conjunction with a CNC quenching machine tool. The sensor does not move during quenching, and the CNC quenching machine tool drives the kingpin to rotate at a constant speed (the rotation speed can be set), which realizes simultaneous quenching of the entire quenching part and ensures the stability of the kingpin. The quenching effect makes the hardness of the kingpin after quenching reach 58-63HRC, which meets its working requirements.

The king pin of the steering knuckle is quenched and heat-treated by medium-frequency induction hardening equipment, which avoids cracks, oxidation, decarburization and uneven quenching defects caused by traditional heat treatment, greatly improves its hardness and service life, and meets its working requirements. Safe driving provides a reliable guarantee.
