1. Adjust the moving speed between the piston rod and the sensor switch to avoid the occurrence of heat-treated soft bands.
2. Appropriately expand the output power of electromagnetic induction heating, so that the surface strength and reasonable hardening layer deeply meet the technical requirements of the product.
3. After quenching and tempering, for workpieces that need to be straightened, it is necessary to ensure that the internal stress caused by straightening does not hinder subsequent machining and use, and carry out stress relief when necessary. The piston rod is mainly used as a connecting part to support the work of the piston. Since the precision piston rod is a connecting part used to support the piston to do work, in this regard, we will also notice that it must be connected to the piston, and the connection must not only ensure its firmness, but also pay attention to preventing loosening. Only in this way can it be ensured that the normal work between the piston rod and the piston can be effectively ensured. At this time, we should also pay attention to the anti-loosening method of the connection between the precision piston rod and the piston. In actual application, it should be noted that the connecting structure of the piston and the piston rod can be mainly divided into two types: integral type and assembled type.
