The ball pin is a key component to ensure the stability of the car's handling, smoothness, comfort, safety and correct and accurate driving of the car. It is also called a ball hinge and a ball joint. It is one of the important security parts on the car. In recent years, a new trend has emerged in the induction heat treatment of ball pin parts, that is, the requirements for the depth and range of the hardened layer of induction hardened parts are becoming more and more stringent, and the requirements for the surface roughness of the parts after quenching are getting higher and higher. Generally, the ball pin parts of trucks or heavy vehicles are large in size, and the hardened layer range requires 1-3mm. The quenching of the ball pin is carried out by the high-frequency induction quenching equipment produced by our company.
The ball pin is quenched, using inner hole quenching and profiling inductors, and the ball seat and the ball head are quenched and heat treated respectively. The ball pin is quenched by high-frequency induction hardening equipment, which has the advantages of fast heating speed, uniform heating temperature, small deformation, etc., and the equipment has the advantages of simple operation, perfect function, energy saving and environmental protection, etc. It is a good equipment for quenching heat treatment of workpieces.
