The workbench 4 can be used to place the stamped plate for stamping operations, and the body 1 is provided with a protective component 5 to prevent debris from entering during the stamping process, the protective component 5 is provided with a striking component 6 for knocking the side wall of the stamping plate 3, the protective component 5 is provided with an adjusting component 7 for shielding the bottom of the stamping plate 3, and the workbench 4 is provided with a positioning component 8 for clamping the workpiece.

[0030] In order to prevent impurities from entering the stamped workpiece during the stamping process, the specific protection assembly 5 includes a connecting rod 501, a connecting block 502, a transmission rod 505, a stopper 506, a return spring 507, a support block 508, a rotating rod 509, a protection plate 510, a rotating block 511, a slider 512, a transmission block 503 and an annular block 504;A connecting rod 501 passes through the workbench 4, and is slidably connected at the penetration point. A connecting block 502 is fixed on the top of the connecting rod 501, and a transmission rod 505 is fixed on the bottom of the connecting block 502. The transmission rod 505 passes through the workbench 4, and is slidably connected at the penetration point. A stopper 506 is fixed on the bottom of the transmission rod 505, and a return spring 507 is fixed on the top of the stopper 506. The top of the return spring 507 is at the bottom of the workbench 4. By setting the return spring 507, the transmission rod 505 can be reset. A transmission block 503 is fixed on the top of the connecting block 502, and an annular block 504 is fixed on the end of the transmission block 503 away from the connecting block 502. The bottom of the annular block 504 fits with the top of the stamping plate 3. When the cylinder 2 is started, When the stamping plate 3 is controlled to move downward, the stamping plate 3 will not squeeze the annular block 504. Because the reset spring 507 is in a compressed state, the transmission rod 505 will move downward, so that the transmission rod 505 drives the connecting block 502 to move downward, and drives the connecting rod 501 to move downward. Therefore, the connecting block 502 drives the transmission block 503 to move downward. A support block 508 is fixed on the inner side of the body 1. The support block 508 is provided with two groups, and the two groups of support blocks 508 are symmetrically arranged with the center line in the vertical direction of the workbench 4 as the symmetry axis. A rotating rod 509 runs through the support block 508, and the support block 508 is rotatably connected with the rotating rod 509 at the penetration point. A protective plate 510 is fixed to the outer wall of the rotating rod 509. By setting the protective plate 51 0 can play the effect of shielding the workbench 4, preventing impurities from entering the workpiece from the front during the stamping process, which will affect the quality of sheet stamping. Rotating blocks 511 are fixed at both ends of the rotating rod 509, and a slider 512 is slidably installed on the top of the rotating block 511. The top of the slider 512 is hinged to the bottom of the connecting rod 501. When the connecting block 502 drives the connecting rod 501 to move downward, the connecting rod 501 squeezes the slider 512 to slide in the rotating block 511, and the rotating block 511 can be reversed at the bottom of the workbench 4, so that the rotating block 511 drives the rotating rod 509 to reverse, and the protective plate 510 is reversed. The front of the workbench 4 can be shielded by the protective plate 510, which can play the effect of shielding the workbench 4. During the stamping process, impurities fly in, affecting the quality of sheet stamping. The protection of the protective plate 510 can prevent the entry of impurities. When the stamping is completed, the cylinder 2 is controlled to move the stamping plate 3 upward. When the stamping plate 3 moves upward and contacts the annular block 504, the annular block 504 will move upward, driving the transmission block 503 to move upward, driving the connecting block 502 to move upward, driving the connecting rod 501 and the transmission rod 505 to move upward, causing the stopper 506 to drive the return spring 507 to compress, causing the slider 512 to drive the rotating block 511 to rotate forward, causing the rotating rod 509 to drive the protective plate 510 to rotate forward, so that the protective plate 510 does not block the workbench 4, thereby facilitating the picking up and placement of the workpiece. ;

[0031] In order to further prevent impurities from adhering to the stamping plate 3 during the stamping process and affecting the stamping quality, the specific striking assembly 6 includes a rotating cylinder 602, an arc-shaped slide groove 603, an L-shaped fixed rod 601, a fixed sleeve 604, a connecting spring 606, a rotating rod 605 and a striking ball 607; the transmission block 503 is penetrated by the rotating cylinder 602, and the penetration is rotatably connected, the outer wall of the rotating cylinder 602 is provided with an arc-shaped slide groove 603, the inner side of the body 1 is fixed with an L-shaped fixed rod 601, the L-shaped fixed rod 601 penetrates the arc-shaped slide groove 603, and the penetration is fitted, the outer wall of the rotating cylinder 602 is fixed with a fixed sleeve 604, the inner side of the fixed sleeve 604 is fixed with a connecting spring 606, the side wall of the connecting spring 606 is fixed with a rotating rod 605, the rotating rod 605 is slidably installed on the inner wall of the fixed sleeve 604, the end of the rotating rod 605 away from the fixed sleeve 604 is fixed with a striking ball 607, and the stamping plate 3 moves upward to contact with the ring When the annular block 504 is fitted, the hitting ball 607 will be aligned with the stamping plate 3. When the stamping plate 3 presses the annular block 504 upward and moves upward, the rotating cylinder 602 will drive the hitting ball 607 to move upward as well, so that the hitting ball 607 will always be aligned with the stamping plate 3. When the rotating cylinder 602 moves upward, the arc groove 603 will move on the L-shaped fixed rod 601, and the arc groove 603 will be subjected to the extrusion force, so that the rotating cylinder 602 will rotate, which can drive the fixed sleeve 604 to rotate, and the rotating rod 605 will drive the hitting ball 607 to rotate, so that the hitting ball 607 will hit the side wall of the stamping plate 3, causing the stamping plate 3 to vibrate. Therefore, impurities attached to the stamping position at the bottom of the stamping plate 3 can be vibrated and fall off, so that the impurities fall on the stamped workpiece. When taking the stamped workpiece, the impurities on the workpiece can be removed or removed when the workpiece is subsequently cleaned.

[0032] In order to more effectively protect the stamping plate 3 when the stamping plate 3 is not in use, specifically, the adjustment component 7 includes a groove 701, a threaded rod 702, a knob 709, a threaded sleeve 703, a movable rod 708, a hinge block 707, a support plate 704, a hinge rod 705 and a shielding plate 706; the groove 701 is provided on the transmission block 503, the inner wall of the groove 701 is rotatably mounted with a threaded rod 702, the top of the threaded rod 702 is fixed with a knob 709, the outer wall of the threaded rod 702 is threadedly connected with a threaded sleeve 703, and the threaded sleeve 70 The threaded sleeve 703 is slidably mounted on the inner wall of the groove 701. When the knob 709 is rotated forwards and backwards, the threaded sleeve 703 can be moved on the threaded rod 702. A support plate 704 is fixed on the inner side of the transmission block 503. A hinged rod 705 is hinged on the support plate 704. A shielding plate 706 is fixed on the side of the hinged rod 705 away from the support plate 704. There are two groups of shielding plates 706, and the two groups of shielding plates 706 are symmetrically arranged with the center line of the stamping plate 3 in the vertical direction as the symmetry axis. When the stamping plate 3 is not needed, the stamping plate 3 is controlled to return to its original position upwards. By turning the knob 709 forward, the threaded sleeve 703 can be moved upward. The end of the threaded sleeve 703 is hinged with a movable rod 708. A hinge block 707 is fixed to the bottom of the shielding plate 706. The end of the movable rod 708 away from the threaded sleeve 703 is hinged on the hinge block 707. When the threaded sleeve 703 moves upward, the threaded sleeve 703 can squeeze the movable rod 708, so that the movable rod 708 rotates at the hinge, so that the movable rod 708 squeezes the hinge block 707 to rotate, so that the shielding plate 706 rotates, and the two sets of shielding plates 706 can be rotated toward the stamping plate 3. , so that the shielding plate 706 is rotated to shield and protect the stamping plate 3 to prevent the stamping plate 3 from being exposed to the outside and adhering to impurities when the stamping plate 3 is not in use, thereby affecting the subsequent stamping operation. When the rotary knob 709 is reversed, the threaded rod 702 can drive the threaded sleeve 703 to move downward, and the threaded sleeve 703 can move downward. The movable rod 708 is pulled by the threaded sleeve 703, and the hinge block 707 is pulled by the movable rod 708 to rotate the shielding plate 706 to the side away from the stamping plate 3, so that the shielding plate 706 can be folded up for stamping operations.

[0033] In order to maintain stability during the stamping of the workpiece, specifically, the positioning assembly 8 includes a slide groove 801, a positioning plate 802, a push rod 804 and a push block 803; the slide groove 801 is opened on the top of the workbench 4, and the inner wall of the slide groove 801 is slidably installed with a positioning plate 802, and the slide groove 801 and the positioning plate 802 are provided with two groups, and the two groups of slide grooves 801 and the positioning plate 802 are symmetrically arranged with the center line in the vertical direction of the workbench 4 as the symmetry axis, and the side wall of the connecting block 502 is fixed with a push block 803, and the push block 803 is hinged with a push rod 804, and the end of the push rod 804 away from the push block 803 is hinged on the positioning plate 802. During stamping, the reset spring 507 will drive the stopper 506 and the transmission rod 505 to move downward, which will cause the connecting block 502 to move downward, and drive the push block 803 to move downward, so that the push block 803 squeezes the push rod 804, and drives the two sets of positioning plates 802 to approach each other. The positioning plates 802 can be used to clamp and position the workpiece on the workbench 4 to prevent displacement during stamping. When the stamping is completed, the stamping plate 3 squeezes the transmission block 503 and the connecting block 502 to move upward, which will cause the push block 803 to pull the push rod 804, so that the two sets of positioning plates 802 move away from each other, and the workpiece can be clamped and positioned, and the workpiece can be taken.

[0034] Working principle: When it is necessary to perform stamping operation on the plate, the plate can be placed on the workbench 4, and the stamping plate 3 can be moved downward by starting the cylinder 2, so that the stamping plate 3 does not squeeze the annular block 504. Because the reset spring 507 is in a compressed state, the stopper 506 drives the transmission rod 505 to move downward, and drives the connecting rod 501 to move downward. Therefore, the connecting block 502 drives the transmission block 503 to move downward. When the connecting block 502 drives the connecting rod 501 to move downward, the connecting rod 501 squeezes the slider 512 to slide in the rotating block 511, and the rotating block 511 can be reversed at the bottom of the workbench 4, so that the rotating block 511 drives the rotating rod 509 to reverse, and the protective plate 510 is reversed. The workbench 4 can be reversed through the protective plate 510. The front side is blocked, so that impurities can be prevented from flying in during the stamping process and affecting the quality of the sheet metal stamping. The protection of the protective plate 510 can prevent the entry of impurities. After the stamping is completed, the cylinder 2 is controlled to move the stamping plate 3 upward. When the stamping plate 3 moves upward and contacts the annular block 504, the annular block 504 will move upward, driving the transmission block 503 to move upward, and the connecting block 502 to move upward, driving the connecting rod 501 and the transmission rod 505 to move upward, which will cause the stopper 506 to drive the reset spring 507 to be compressed, and the slider 512 will drive the rotating block 511 to rotate forward, so that the rotating rod 509 drives the protective plate 510 to rotate forward, so that the protective plate 510 does not block the workbench 4, thereby facilitating the picking up and placement of the workpiece.

[0035] When the stamping plate 3 moves upward to fit with the annular block 504, the hitting ball 607 will be aligned with the stamping plate 3. When the stamping plate 3 squeezes the annular block 504 upward and moves upward, and when the rotating cylinder 602 moves upward, the arc groove 603 will move on the L-shaped fixed rod 601, and the arc groove 603 will be subjected to the extrusion force, so that the rotating cylinder 602 will rotate, which can drive the fixed sleeve 604 to rotate, and the rotating rod 605 drives the hitting ball 607 to rotate, so that the hitting ball 607 hits the side wall of the stamping plate 3, causing the stamping plate 3 to vibrate, so that impurities attached to the stamping position at the bottom of the stamping plate 3 can be vibrated and fall off.

[0036] When the stamping plate 3 is no longer needed, the stamping plate 3 is controlled to return to its original position, and the threaded sleeve 703 can be moved upward by the forward rotation button 709, so that the threaded sleeve 703 can squeeze the movable rod 708, so that the movable rod 708 rotates at the hinge, and the movable rod 708 squeezes the hinge block 707 to rotate, so that the shielding plate 706 rotates, and the two sets of shielding plates 706 can be rotated toward the stamping plate 3, so that the shielding plate 706 is rotated to shield and protect the stamping plate 3, to prevent the stamping plate 3 from being exposed to the outside and adhering to impurities when the stamping plate 3 is not in use, thereby affecting the subsequent stamping operation.

[0037] When the stamping plate 3 is punching downward, the reset spring 507 will drive the stopper 506 and the transmission rod 505 to move downward, which will cause the connecting block 502 to move downward, drive the push block 803 to move downward, and cause the push block 803 to squeeze the push rod 804, driving the two sets of positioning plates 802 to approach each other. The positioning plates 802 can be used to clamp and position the workpiece on the workbench 4 to prevent displacement during stamping.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
