The specific working process of the device is as follows: firstly, a workpiece penetrates through the U-shaped block 3 and the clamping block 11 and is placed into the upsetting module 10, then a punch press or a press machine is started to drive the first upper template 38 and the second upper template 39 to simultaneously press downwards, and therefore the first inclined punching plate 1 and the second inclined punching plate 15 are driven to simultaneously move downwards; at this time, since the length of the second inclined punching plate 15 is greater than that of the first inclined punching plate 1, the second inclined punching plate 15 firstly enters the groove between the first roller seat 12 and the second roller seat 20, the second roller 16 is pushed to move in the second roller seat 20 to the side of the disc spring slider 19, the disc spring slider 19 is pushed to move by extrusion, so that the first push rod 22, the first pin 23, the first push rod seat 24 and the second pin 25 are pushed to move simultaneously (at this time, the disc spring 21 compresses the accumulated force), the third pin 26 and the fourth pin 32 are pushed by the second pin 25, but the third pin 26 is limited by the movable push rod seat 34 and cannot move, so that the force acts on the fourth pin 32 to displace the fourth pin 32, the second push rod 33 is pushed to move inwards, a lateral clamping force is provided for the clamping block 11, and the clamping block 11 can clamp the workpiece to prevent the workpiece from moving backwards during forging; at this point the second spring 27 is compressed and the second spring guide 28 and the return slider 37 move backwards.

When a workpiece is clamped, the first inclined punching plate 1 moves downwards into a V-shaped groove between the upsetting slide block 8 and the U-shaped block 3 to push the upsetting slide block 8 to translate, the upsetting slide block 8 pushes the circular press plate 9 and the upsetting module 10 to move forwards to complete one-time forging and pressing, at the moment, the first spring guide rod 5 is driven by the upsetting slide block 8 to move forwards, and the first spring 4 is compressed.

Then the punch press or the press machine drives the first upper template 38 and the second upper template 39 to move upwards simultaneously, drives the first inclined punching plate 1 and the second inclined punching plate 15 to move upwards simultaneously, the first spring 4 releases the compression state to provide restoring force, pushes the first spring guide rod 5 to move backwards, and drives the upsetting slide block 8, the circular press plate 9 and the upsetting module 10 to move backwards, so that the workpiece is demoulded; similarly, the second spring 27 and the belleville spring 21 provide restoring force when the compression state is released, and respectively push the reset slider 37, the second spring guide 28, the second pin 25, the first push rod seat 24, the first pin 23, the first push rod 22, the belleville spring slider 19 and the second roller 16 to move, so that the component providing the lateral clamping force returns to the initial position, and the clamping state of the clamping block 11 is released. Waiting for the next job.
