[0042] When the device needs to be used, first, the part to be processed is stably placed inside the lower die 32 above the stripping block 34, and then the hydraulic cylinder 37 is opened. The hydraulic cylinder 37 drives the output end connected hydraulic rod 38 to slide along the guide sleeve 31, and then the hydraulic rod 38 drives the upper die 30 to descend, and then the upper die 30 and the lower die 32 are combined to stamp and form the part. At the same time, the combination of the upper die 30 and the lower die 32 will apply pressure to the stripping block 34, and then the stripping block 34 will drive the stripping rod 33 to slide downward, and at the same time the stripping block 34 will cooperate with the movable frame 36 to extrude the push spring 35. When the stamping and forming is completed, the hydraulic cylinder 37 drives the upper die 30 to reset through the hydraulic rod 38, and then the push spring 35 is no longer subjected to the force of the hydraulic rod 38. Then the push spring 35 automatically resets, and then the push spring 35 pushes the stripping block 34 and the stripping rod 33 to reset, so that the stripping block 34 pushes the formed part, thereby easily completing the stripping operation, and then the formed part can be taken away. Between stamping and forming, the knob 41 can also be rotated, so that the knob 41 drives the screw rod 40 to move, and then the screw rod 40 and the knob 41 cooperate to no longer clamp the fixed seat 39 and the movable frame 36. Then the movable frame 36 slides along the inside of the fixed seat 39, and then the movable frame 36 and the fixed seat 39 are clamped again through the knob 41 and the screw rod 40 to fix the movable frame 36. At this time, the push spring 35 will move with the movable frame 36, and then the stripping block 34 will move with the push spring 35, thereby changing the force applied by the stripping block 34 to the push spring 35 when the dies are combined, thereby changing the reset force and reset speed of the push spring 35 when the hydraulic rod 38 rises.
