Problems solved by technology

[0002] Most of the induction hardening equipment in the prior art adopts static induction heating and quenching technology, while the dynamic continuous induction heating and quenching equipment adopts the authorized announcement number CN208234951U application number: 2018207241905 Utility model name: continuous induction hardening and tempering equipment for shaft parts. The equipment is only suitable for single-track transportation of cylindrical bearing parts, and the biaxial rubbing of the workpiece makes the workpiece undergo induction heating and quenching while rotating. The single-track transportation leads to low production efficiency and low automation of the equipment, and the application field is limited. It is suitable for continuous induction heating and quenching process of large and heavy parts such as chain rail links for military tanks and chain rail links for construction machinery. There has been no good solution to this defect
