Abstract
The application discloses a novel forging process of a spline shaft fork, and comprises the following steps: blank preparation: cutting round steel by operating a high-speed circular saw machine, and cutting a blank with a specified length; local heating; removing the oxide skin; closed extrusion blanking; (5) final forging; edge cutting; quenching and tempering treatment; and shot blasting. The application has the following technical effects: reducing the flash of the fork part, improving the material utilization rate; reducing the damage to the equipment, improving the product yield; further reducing the blank weight, improving the material utilization rate; reducing the production rhythm by half, reducing the operation time, and improving the production efficiency; improving the service life of the die, and reducing the production cost; each forging step of the new process can be well positioned, the equipment required by adjacent processes has good connectivity, and the foundation for automatic production can be provided.
