The rack 607 is fixedly connected to the second connecting rod 606, and the rack 607 is meshed with the gear 605.

[0051] When the sliding plate 403 moves left and right, the movable plate drives the second connecting rod 606 to move left and right, the second connecting rod 606 moves left and right and drives the rack 607 to move left and right, the rack 607 moves left and right and drives the gear 605 to rotate, the gear 605 rotates and drives the fixed rod 601 to rotate, the fixed rod 601 rotates and drives the first curved rod 602 to rotate, the first curved rod 602 rotates and drives the second curved rod 603 to rotate, the second curved rod 603 rotates and drives the push plate 604 to move left and right, thereby cleaning the fixed frame 202.

[0052] The fixing rod 601 is rotatably connected to the mounting platform 201 via an extended linear bearing.

[0053] The extended linear bearing can increase the stability of the fixed rod 601 when it rotates.

[0054] Working principle: When the workpiece needs to be stamped, the staff puts the workpiece on the sliding plate 403, and then turns on the oil pump 502. The oil pump 502 sucks the hydraulic oil in the second telescopic rod 304 into the second connecting pipe 503. Then the hydraulic oil enters the oil tank 501 through the second connecting pipe 503, and the second telescopic rod 304 is shortened. The shortening of the second telescopic rod 304 drives the fixed plate 302 to move downward, and the downward movement of the fixed plate 302 drives the first connecting rod 507 to move downward, drives the stamping column 303 to move downward, and drives the second telescopic rod 304 to move downward.

[0055] When the first connecting rod 507 moves downward, the first connecting rod 507 drives the second piston 506 to move downward. When the second piston 506 moves downward, negative pressure is formed in the second sealing cylinder 505, and the hydraulic oil flows from the third telescopic rod 404 into the second sealing cylinder 505. The third telescopic rod 404 is shortened. The shortening of the third telescopic rod 404 drives the sliding plate 403 to move to the left. The sliding plate 403 drives the workpiece and the second connecting rod 606 to move to the left until the sliding plate 403 moves to the top of the fixed frame 202. When the second connecting rod 606 moves to the left, the second connecting rod 606 drives the rack 607 to move to the left, and the rack 607 moves to the left and drives the gear 605 to rotate. The gear 605 rotates, which drives the fixed rod 601 to rotate. The fixed rod 601 rotates and drives the first curved rod 602 to rotate. The first curved rod 602 rotates and drives the second curved rod 603 to rotate. The second curved rod 603 rotates and drives the push plate 604 to move to the left. The push plate 604 scrapes away impurities above the fixed frame 202.

[0056] When the punching column 303 moves downward, the punching column 303 moves downward until it contacts the workpiece, and punches the workpiece.

[0057] When the second telescopic rod 304 moves downward, the second telescopic rod 304 drives the partition plate 305 to move downward until the partition plate 305 contacts the sliding plate 403. After the partition plate 305 contacts the sliding plate 403, the partition plate 305 compresses the second telescopic rod 304 to shorten, and the hydraulic oil in the second telescopic rod 304 enters the first connecting pipe 307, and then the hydraulic oil enters the first sealing cylinder 203 through the first connecting rod 507, and the hydraulic oil pushes the first piston 204 to move upward. When the first piston 204 moves upward, it drives the bearing column 205 to move downward until the bearing column 205 contacts the workpiece, and the workpiece is punched under the action of the punching column 303 and the bearing column 205.

[0058] When the stamping of the workpiece is completed, the staff turns on the oil pump 502, and the oil pump 502 sucks the hydraulic oil from the oil tank 501 into the second connecting pipe 503. Then the hydraulic oil enters the second telescopic rod 304 to drive the second telescopic rod 304 to extend. The extension of the second telescopic rod 304 drives the fixed plate 302 to move upward. The upward movement of the fixed plate 302 drives the stamping column 303 to move upward, drives the second telescopic rod 304 to extend, and drives the first connecting rod 507 to move upward.

[0059] When the punching column 303 moves upward, the punching column 303 is separated from the workpiece.

[0060] When the second telescopic rod 304 is extended, the hydraulic oil flows from the hydraulic oil in the first sealing cylinder 203 into the second telescopic rod 304, and the first piston 204 moves downward, which drives the bearing column 205 to move downward, and the bearing column 205 is separated from the workpiece.

[0061] When the first connecting rod 507 moves upward, the first connecting rod 507 drives the second piston 506 to move upward, and the second piston 506 pushes the hydraulic oil in the second sealing cylinder 505 into the third telescopic rod 404, and the third telescopic rod 404 extends. The extension of the third telescopic rod 404 drives the sliding plate 403 to move rightward, and the movement of the sliding plate 403 to the right drives the workpiece to move rightward, drives the second connecting rod 606 to move rightward, and the sliding plate 403 drives the workpiece to move rightward until the sliding plate 403 contacts the support plate.

[0062] When the second connecting rod 606 moves to the right, the second connecting rod 606 drives the rack 607 to move to the right, the rack 607 drives the gear 605 to rotate, the gear 605 drives the fixed rod 601 to rotate, the rotation of the fixed rod 601 drives the first curved rod 602 to rotate, the rotation of the first curved rod 602 drives the second curved rod 603 to rotate, the rotation of the second curved rod 603 drives the push plate 604 to move to the right, and the push plate 604 scrapes away impurities above the fixed frame 202.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
