[0033] Embodiment 2:

[0034] Based on the first embodiment, Figure 6 , Figure 7As shown, the upper sides of the left and right ends of the fixed plate 701 are provided with a second slide groove 721, the inner sides of the second slide grooves 721 on the left and right sides are slidably connected with a second slider 722, the upper sides of the second sliders 722 on the left and right sides are fixedly connected with an L-shaped plate 723, the outer sides of the L-shaped plate 723 are fixedly connected with a clamping block 724, the lower side of the second slider 722 is fixedly connected with a rotating block 1 725, the outer side of the rotating block 1 725 is rotatably connected with a control plate 726, the outer side of the lower end of the control plate 726 is rotatably connected with a rotating block 2 727, the lower side of the rotating block 2 727 is fixedly connected with a square block 728, the front side of the square block 728 is fixedly connected with a control block 731, and a telescopic support is fixedly connected between the control block 731 and the fixed plate 701. The rod 732 is connected to the spring 733, and the upper side of the square block 728 is fixedly connected with a top block 729, and the outer side of the top block 729 is rotatably connected with a seesaw 730.

A contact block 735 is fixedly connected to the upper side of the seesaw 730, and an arc block 736 is fixedly connected to the upper side of the contact block 735. The rear side of the placement plate 715 is fixedly connected with an arc plate 716, and the arc plate 716 and the rotating plate 714 are both slidably connected with the arc block 736.

The placing plate 715 is slidably connected. When the stamping is initially performed, the spring 1 733 is in a compressed state, and the arc block 736 is located below the placing plate 715 and contacts the placing plate 715.

The shaped plate 723 drives the clamping block 724 to move, so that the clamping blocks 724 on the left and right sides are close to each other, so that the clamping blocks 724 limit the left and right sides of the metal plate, and the friction between the metal plate and the placing plate 715 is greater than the friction between the metal plate and the clamping block 724, so that when the placing plate 715 moves backward, the metal plate and the clamping block 724 are separated. After the discharge is completed, the placing plate 715 is reset, and the placing plate 715 drives the rotating plate 714 to move forward, so that the rotating plate 714 is against the arc block 736, so that the arc block 736 drives the seesaw 730 on the contact block 735 to rotate, and the seesaw 730 drives the square block 728 to rise, so that the square block 728 drives the clamping blocks 724 on both sides to move away from each other, which is convenient for the next stamping.

[0035] Embodiment three:

[0036] Based on the first embodiment, Figure 8 , Fig. 9As shown, a T-shaped plate 737 is fixedly connected to the rear side of the fixing frame 2, a connecting plate 738 is fixedly connected between the left and right top plates 704, a lifting rod 739 is arranged on the upper side of the connecting plate 738, the lower end of the lifting rod 739 passes through the lower side of the connecting plate 738 and is fixedly connected to a push plate 740, the upper end of the lifting rod 739 is fixedly connected to a moving plate 741, a screw 742 is rotatably connected between the connecting plate 738 and the T-shaped plate 737, a gear 2 743 is fixedly connected to the outer side of the lower end of the screw 742, a mounting block 2 745 is fixedly connected to the upper side of the connecting plate 738, a sliding rod 746 is fixedly connected to the front side of the mounting block 2 745, a slip ring 747 is slidably connected to the outer side of the sliding rod 746, a fixed block 748 is fixedly connected to one side of the slip ring 747, a tooth plate 2 744 meshing with the gear 2 743 is fixedly connected to the outer side of the fixed block 748, and a tooth plate 2 744 meshing with the gear 2 743 is fixedly connected to the other side of the slip ring 747 A front plate 749 is fixedly connected to the side, a spring 2 750 is fixedly connected between the slip ring 747 and the mounting block 2 745, the screw 742 is threadedly connected to the movable plate 741, and the lifting rod 739 is slidably connected to the connecting plate 738. When the placing plate 715 moves backward, the placing plate 715 drives the movable block 706 to move backward, and the movable block 706 pushes the front plate 749 to move backward, the front plate 749 drives the slip ring 747 to move backward, the slip ring 747 drives the fixed block 748 to move backward, the fixed block 748 drives the tooth plate 2 744, the tooth plate 2 744 drives the gear 2 743 to move backward, the gear 2 743 drives the screw 742 to rotate, the screw 742 drives the movable plate 741 to descend, the movable plate 741 drives the lifting rod 739 to descend, and the lifting rod 739 drives the push plate 740 to descend, so that the push plate 740 descends and pushes the metal plate on the placing plate 715, so that the metal plate is discharged and descended quickly, and the discharge is smoother.

When it moves to the stamping area, stop controlling the placement plate 715 to move. At this time, the arc block 736 is separated from the placement plate 715, and the square block 728 is lowered under the action of the spring 1 733. Under the action of the control plate 726, the slider 2 722, and the L-shaped plate 723, the clamping blocks 724 on the left and right sides limit the metal plate, which is convenient for the metal plate to be stable during stamping, and then The rear control hydraulic cylinder 3 drives the punching block 4 to descend, so that the punching block 4 punches the metal plate. After the punching is completed, the placement plate 715 moves backward, and under the action of the inclined plate 709 and the slide groove 710, the placement plate 715 is lowered. At the same time, under the action of the rotating rod 712, the gear 1 713 and the tooth plate 1 718, the placement plate 715 is rotated and tilted. At the same time, the upper moving block 706 drives the front plate 749 to move backward, and under the action of the tooth plate 2 744 and the gear 2 743, the control screw 742 rotates to make the push plate 740 descend, so that the metal plate on the placement plate 715 is quickly discharged into the collection box 9. The operation is simple and the workload of the staff is reduced.
