step 2: opening the mold: the upper die is retreated to the uppermost limit, the ejection cylinder is retreated to the lowermost limit, at the moment, the inclined wedge combination is in a separated state, and the forging blank is placed in the forging placing groove;
and step 3: die assembly: the upper die descends, the punch contacts and extrudes the inclined wedge combination, the inclined wedge combination approaches to each other, a closed forging cavity is formed above the forging placing groove, forging force is formed on a forging blank in the approach process of the inclined wedge combination, the forging force is used for forging and forming the forging blank, and in the process, the ejection cylinder is located at the lower limit position and does not move;
the method specifically comprises the following steps: the two female die limiting blocks are firstly contacted with two ends of an upper female die at the same time, in the process that the female die limiting blocks continue to descend, the inclined surfaces of the female die limiting blocks extrude the two upper female die blocks to move relatively and approach to each other, finally, the upper female die is closed to cover the upper part of a lower female die, the forging space formed by the upper female die and the lower female die does not change any more after the upper female die moves downwards to the lower limit position, in the process, the upper punch slider downwards extrudes the inclined wedge II, the two inclined wedges II approach to each other, and as the thickness of the upper punch slider is larger, the inclined surfaces are longer, and under the condition that the closing force of the upper female die is not increased any more by the female die limiting blocks, the lateral forming force is continuously provided for the inclined wedge II to drive the forging of the punch assembly;
and 4, step 4: opening the mold: after the upper die moves upwards to the uppermost position, the ejection cylinder starts to move upwards for ejection, the ejection cylinder drives the ejection block below the forge piece to move upwards to eject the forge piece, the inclined wedge combination is opened, and the concrete process is as follows:
4.1 pushing the sliding block push rod to move upwards, the sliding block push rod firstly contacts the inclined wedge I to push the inclined wedge I upwards, the upper female die is separated,
4.2, the sliding block push rod continues to move upwards to contact the inclined wedge II, the inclined wedge II is ejected upwards and separated from the inclined wedge, and the punch assembly is separated from the forge piece;
4.3 the sliding block push rod continues to move upwards, the sliding block push rod finally pushes the push rod above to move upwards, the top of the push rod pushes the ejection block to move upwards, and the top of the ejection block jacks the forge piece;
and 5: and (5) taking out the forged piece.
