Detailed Description

The utility model will now be described in detail with reference to the drawings and specific examples.

Referring to fig. 1-3, a combined shaping die for rolling a shaft sleeve comprises a die shell 1, wherein an inner cavity of the die shell 1 is provided with an alloy female die 2, and the bottom end of the die shell 1 is connected with a gland 3; a shaping cavity is formed in the center of the alloy female die 2, a discharge hole 31 is formed in the center of the gland 3, and the shaping cavity is communicated with the discharge hole 31. When the rolled shaft sleeve is subjected to shaping processing, the rolled shaft sleeve is directly placed at the inlet of the shaping cavity of the alloy female die, the feeding mechanism pushes the shaft sleeve to downwards pass through the shaping cavity, the shaping processing of the outer circle of the rolled shaft sleeve is completed, and finally the rolled shaft sleeve is discharged from the discharge hole. When the rolled shaft sleeve is sent out from the shaping cavity of the alloy female die, the discharging hole plays a role in restricting the discharging direction of the shaft sleeve, so that the shaft sleeve can be ensured to accurately fall into a discharging track of shaping equipment.

Further, the inner cavity of the mould shell 1 is coaxially arranged with the outer circle of the alloy female mould 2 and is in clearance fit with the outer circle of the alloy female mould. The shaping precision of the die is ensured, and a certain gap exists at the same time, so that the alloy female die can be conveniently put in or taken out. The top of the inner cavity of the die shell 1 is provided with a pressing opening section 11 protruding towards the center, the periphery of the top of the alloy female die 2 is provided with a groove, and the pressing opening section 11 is matched with the groove.
