The inner side of the movable seat 51 is provided with a ejecting piece 54 for ejecting the workpiece from the die 4 by contacting the arc-surface protrusion 55.

[0022] The workpiece is stamped and formed by the stamping mechanism 3, and then the hydraulic rod 53 is controlled to make the movable seat 51 slide along the slide groove 52, so that the die 4 deviates from the stamping mechanism 3 with the workpiece. When the movable seat 51 moves to the position of the arc-surface protrusion 55, the ejecting piece 54 on the inner side of the movable seat 51 contacts the arc-surface protrusion 55 and ejects the workpiece on the die 4, thereby realizing rapid unloading of the workpiece and greatly reducing the amount of manual labor.

[0023] Among them, the ejecting member 54 includes a ejector plate 541, which is slidably connected to the bottom wall of the die 4, and the bottom of the ejector plate 541 is fixedly connected to a ejector rod 542 that penetrates the movable seat 51, and the bottom end of the ejector rod 542 is fixedly connected to a mounting seat 543, and the inner side of the mounting seat 543 is rotatably connected to a pressure wheel 544, and the pressure wheel 544 contacts the bottom surface of the slide groove 52, and a spring 545 is sleeved on the ejector rod 542, and the top end of the spring 545 contacts the bottom wall of the movable seat 51, and the bottom end of the spring 545 contacts the mounting seat 543. By controlling the hydraulic rod 53, the movable seat 51 slides along the slide groove 52, which makes the pressure wheel 544 roll along the bottom surface of the slide groove 52. When the pressure wheel 544 contacts the arc-surface protrusion 55, the pressure wheel 544 is squeezed by the arc-surface protrusion 55 and moves upward, which makes the mounting seat 543 drive the push rod 542 to slide upward, and the push plate 541 pushes the workpiece in the die 4 out to achieve rapid material unloading.

[0024] Among them, the stamping mechanism 3 includes a hydraulic rod 31, the output end of the hydraulic rod 31 is fixedly connected to a movable plate 32, and a stamping part 33 for stamping the workpiece by downward translation is arranged at the bottom of the movable plate 32.

The stamping part 33 includes two sliding rods 331 passing through the movable plate 32, and the two sliding rods 331 are slidably connected to the two ends of the movable plate 32 respectively, and the bottom ends of the two sliding rods 331 are fixedly connected to the same mounting plate 332, and the bottom of the mounting plate 332 is fixedly connected with a punch 333, and the top ends of the two sliding rods 331 are fixedly connected to the limited block 334, and the two sliding rods 331 are both sleeved with a spring 335, and the top ends of the two springs 335 are both in contact with the movable plate 32, and the bottom ends of the two springs 335 are both in contact with the mounting plate 332.

[0025] The working principle and use process of the utility model: during stamping, the movable plate 32 is moved downward by controlling the hydraulic rod 2 31, so that the mounting plate 332 drives the punch 333 to move downward and cooperate with the die 4, thus realizing the stamping of the workpiece, and the spring 2 335 can reduce the instantaneous impact force of the punch 333 on the die 4, effectively avoiding the problem that the die 4 is damaged by excessive impact force;

[0026] When unloading, the movable seat 51 is controlled by the hydraulic rod 53 to slide along the slide groove 52, which makes the pressure wheel 544 roll along the bottom surface of the slide groove 52. When the pressure wheel 544 contacts the arc-surface protrusion 55, the pressure wheel 544 is squeezed by the arc-surface protrusion 55 and moves upward, which makes the mounting seat 543 drive the push rod 542 to slide upward, and the push plate 541 pushes the workpiece in the die 4 out to achieve rapid unloading.
