Automobile half shaft casing forging process
The three-step forming method utilizes three hydraulic presses, one hydraulic press per station, and three stages to form the shaft tube. The forging process is: after the billet is heated, the first forging process is first performed on the first hydraulic press (pressure Type), then the second forging process (squeezing) was carried out on the second hydraulic press, and finally the third forging process (de-extrusion) was completed on the third hydraulic press .
The four-step forming method uses two hydraulic presses to mount the slide table on the hydraulic machine table and the slider, and installs two sets of molds on the upper slide table. Under the action of the push-pull cylinder, the slide table moves along the table and the slider. Therefore, four processes can be performed on two hydraulic presses to form the casing. The forging process is: after the billet is heated, it is transferred to the first hydraulic press. At this time, the first set of mold center on the first hydraulic press coincides with the center of the hydraulic press. The blank is formed in the first station; the workpiece after the pressing is sent to the second station, the push-pull cylinder moves at the same time, the pressure station of the second station coincides with the center of the device, the slider descends, and the second is completed. The forming process is squeezed; the extruded part is transferred to the second hydraulic press, and similar to the first hydraulic press, the reverse extrusion and secondary back-extrusion processes are sequentially performed .
