The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 4 As shown, the present invention provides a metal sheet stamping equipment, comprising: a machine base 1; a stamping assembly 2 disposed on the machine base 1 for stamping metal sheets; a stamping seat 3 fixedly installed on the machine base 1; a cleaning assembly 4 disposed on the machine base 1 for cleaning up waste after stamping; a positioning assembly 5 for positioning the metal sheet; and a pushing assembly 6 located on the stamping seat 3 for pushing out the waste after stamping.

[0025] The stamping assembly 2 includes: a stamping head 201; a lower pressure plate 202 fixedly mounted on the stamping head 201; and a hydraulic cylinder 203 that drives the lower pressure plate 202 to rise and fall, and the hydraulic cylinder 203 is fixedly mounted on the machine base 1.

[0026] The cleaning assembly 4 includes: a cleaning brush 401 slidably mounted on the machine base 1; a first rack 402 fixedly mounted at both ends of the cleaning brush 401; a gear 403 meshing with the first rack 402; a gear shaft 404 fixedly mounted between the two gears 403; and a second rack 405 meshing with the gear shaft 404, with the top of the second rack 405 fixedly mounted on the lower pressure plate 202. It should be noted that positioning blocks are rotatably mounted at both ends of the gear shaft 404 via bearings, and the bottom of the positioning blocks is fixedly mounted on the machine base 1, improving the stability of the rotation of the gear shaft 404.

[0027] A through groove 101 is provided on one side of the surface of the machine base 1, and a collection box 7 is placed on one side of the lower end of the machine base 1, and the collection box 7 is located directly below the through groove 101; when the cleaning brush 401 cleans the waste on the stamping seat 3, the waste falls into the collection box 7 through the through groove 101 for collection.

[0028] During the stamping of the metal sheet by the downward movement of the stamping head 201 at the bottom of the lower pressure plate 202 driven by the hydraulic cylinder 203, the lower pressure plate 202 drives the second rack 405 fixed at the bottom to descend and mesh with the gear shaft 404. This causes the gear shaft 404 to drive the gears 403 fixed at both ends to mesh with the first rack 402, causing the first rack 402 to drive the cleaning brush 401 back to its initial position. After the stamping is completed, the hydraulic cylinder 203 drives the stamping head 201 at the bottom of the lower pressure plate 202 to rise, causing the second rack 405 to drive... When the gear shaft 404 is engaged, it reverses. At this time, the gears 403 at both ends of the gear shaft 404 engage with the first rack 402, pushing the cleaning brush 401 to move towards the stamping seat 3. This cleans the waste generated during stamping on the surface of the stamping seat 3 and sweeps the waste into the collection box 7 below the through groove 101 for collection. This prevents the waste from not being cleaned up in time after the sheet metal is stamped, which could cause the sheet metal to deform when other sheets metal are stamped, thus affecting the quality of the finished product.

[0029] To improve the stability of the sheet metal during stamping, the positioning assembly 5 includes: clamping plates 501 on both sides of the stamping base 3; movable rods 502 that drive the clamping plates 501 to move; positioning sleeves 503 that guide the movement of the clamping plates 501 and are fixedly installed on the machine base 1; a pressure rod 504 that is movably disposed on the machine base 1 and whose upper end is located above one end of the adjacent movable rod 502; a protrusion 505 fixed on one side of the first rack 402 and whose top end rests on the bottom of the adjacent pressure rod 504, the bottom of the pressure rod 504 being rounded to reduce friction with the protrusion 505 and prevent interference; a fixing ring 506 fixedly installed at the lower end of the pressure rod 504; and a first spring 507 fitted on the pressure rod 504, one end of the first spring 507 being fixedly installed on the machine base 1 and the other end of the first spring 507 being fixedly installed on the surface of the fixing ring 506.

[0030] When the first rack 402 drives the cleaning brush 401 to move and clean the waste on the pressing seat 3, after the first rack 402 moves into place, the protrusion 505 fixed on one side of the first rack 402 squeezes and pushes the pressure rod 504 to move upward, so that the inclined surface at the upper end of the pressure rod 504 releases the pressure on the inclined surface of the movable rod 502, and the clamp 501 on the movable rod 502 automatically releases the positioning of the plate, making it easier to pick up and put down the plate.

[0031] One end of the movable rod 502 is set as an inclined surface, and the top of the pressure rod 504 is set as an inclined surface that matches the inclined surface of one end of the movable rod 502.

[0032] When the pressure of the protrusion 505 is released at the bottom of the pressure rod 504, the first spring 507 elastically resets, pushing the fixing ring 506 at the lower end of the pressure rod 504 to descend, causing the inclined surface at the upper end of the pressure rod 504 to press and push the movable rod 502 to move, thereby enabling the clamping plate 501 at the other end of the movable rod 502 to automatically position the plate, reducing the offset of the plate during stamping and affecting the stamping quality.

[0033] To prevent waste parts from remaining in the stamping groove after stamping and affecting subsequent sheet metal stamping, the pusher assembly 6 includes: a push rod 601 that is movably disposed through the stamping base 3 and is located directly below the stamping head 201, extending to the lower end of the machine base 1; a guide sleeve 602 fitted on the push rod 601, with the side wall of the guide sleeve 602 fixedly installed on the machine base 1; a connecting ring 603 fixedly installed on the push rod 601; and a second spring 604 fitted on the push rod 601, with one end of the second spring 604 fixedly connected to the bottom of the connecting ring 603 and the other end of the second spring 604 fixedly installed on the surface of the guide sleeve 602.

[0034] When the stamping head 201 moves upward and releases the pressure on the push rod 601, the second spring 604 is elastically reset after being stressed, pushing the connecting ring 603 upward. This causes the connecting ring 603 to drive the push rod 601 to push out the large pieces of waste generated during stamping, so that the cleaning brush 401 can clean the waste and prevent the waste from remaining in the stamping groove, which would affect subsequent stamping.

[0035] Working principle: When the power is turned on, the hydraulic cylinder 203 is activated during the stamping of metal sheets. The hydraulic cylinder 203 drives the stamping head 201 at the bottom of the lower pressure plate 202 to move down. The lower pressure plate 202 drives the second rack 405 fixed at the bottom to descend and mesh with the gear shaft 404. The gear shaft 404 drives the gears 403 fixed at both ends to mesh with the first rack 402. The first rack 402 drives the cleaning brush 401 to return to the initial position. At the same time, the bottom of the pressure rod 504 is released from the pressure of the protrusion 505. The first spring 507 elastically returns to its original position and pushes the fixing ring 506 at the lower end of the pressure rod 504 to descend. The inclined surface at the upper end of the pressure rod 504 presses and pushes the movable rod 502 to move. This allows the clamping plate 501 at the other end of the movable rod 502 to automatically position the sheet metal and perform the stamping of the sheet metal.

[0036] After the stamping is completed, the hydraulic cylinder 203 drives the stamping head 201 at the bottom of the lower pressure plate 202 to move upward, causing the second rack 405 to engage with the gear shaft 404, causing the gear shaft 404 to reverse. At this time, the gears 403 at both ends of the gear shaft 404 engage with the first rack 402, pushing the cleaning brush 401 to move towards the stamping seat 3 to clean the waste generated during stamping on the surface of the stamping seat 3. At the same time, when the stamping head 201 moves upward and releases the pressure on the push rod 601, the second spring 604 elastically resets after being stressed, pushing the connecting ring 603. The upward movement causes the connecting ring 603 to drive the push rod 601 to push out the large pieces of waste generated by the stamping, so that the cleaning brush 401 can clean the waste and sweep the waste into the collection box 7 below the through groove 101 for collection. When the first rack 402 moves into place, the protrusion 505 fixed on one side of the first rack 402 squeezes and pushes the pressure rod 504 upward, so that the inclined surface at the upper end of the pressure rod 504 releases the pressure on the inclined surface of the movable rod 502, and the clamping plate 501 on the movable rod 502 automatically releases the positioning of the plate, making it easier to pick up and put down the plate.
