[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4This utility model provides an embodiment of a sheet metal forming and stamping device for manufacturing and processing sheet metal parts for household appliances. It includes a base 1, a hydraulic cylinder 21 fixedly connected to the inner top wall of the base 1, an upper die 22 fixedly connected to the output end of the hydraulic cylinder 21, the maximum stroke of the hydraulic cylinder 21 ensuring that the upper die 22 is flush with the bottom wall of the placement plate 5, an electric push rod 10 fixedly connected to the rear wall of the base 1, a protective cover 2 fixedly connected to the output end of the electric push rod 10, the minimum stroke of the electric push rod 10 enabling the protective cover 2 to move vertically to close the base 1, sliding grooves 3 on both side walls of the base 1, sliding strips 4 matching the sliding grooves 3 slidably connected within each of the two sliding grooves 3, and both sliding strips 4 fixedly connected to the inner wall of the protective cover 2, and a servo motor 20 fixedly connected to the bottom wall of the base 1. The output end passes through the inner bottom wall of the base 1 and is fixedly connected to a placement plate 5. The front and rear sides of the top wall of the placement plate 5 are provided with placement grooves 7. The lower mold 6 is engaged in both placement grooves 7. The front and rear sides of the lower part of the placement plate 5 are provided with cavities 17. The bottom walls of both cavities 17 are fixedly connected with springs 18. The tops of both springs 18 are fixedly connected with push rods 8. The diameter of the bottom end of the push rod 8 is larger than the rest of the push rod 8 and is built into the cavity 17. The bottom walls of both cavities 17 are fixedly connected with guide rods 19. The tops of both guide rods 19 pass through the push rods 8. Both springs 18 are sleeved on the outer periphery of the guide rods 19. The tops of both push rods 8 pass through the inner bottom wall of the lower mold 6. The assembly and disassembly assembly is located inside the placement plate 5 and is used to disassemble the lower mold 6.

[0023] By activating the hydraulic cylinder 21, the upper mold 22 connected to the output end can be moved downward and contact the lower mold 6 on its lower side. As the upper mold 22 moves downward, it will also contact the ejector rod 8 and push the ejector rod 8 downward. When the ejector rod 8 moves downward, it will compress the spring 18. When the upper mold 22 moves upward and is pulled out from the lower mold 6, the ejector rod 8 can be reset under the action of the spring 18. At the same time, the guide rod 19 can prevent the spring 18 from bending when compressed. By activating the servo motor 20, the placement plate 5 can be rotated, thereby adjusting the position of the lower mold 6 in the front and rear placement slots 7. By activating the electric push rod 10, the protective cover 2 connected to the output end can be moved up and down. At the same time, when the protective cover 2 moves up and down, it will also drive the slide bar 4 to slide in the slide groove 3. Therefore, the stability of the up and down movement of the protective cover 2 can be ensured by the combined action of the slide groove 3 and the slide bar 4.

[0024] Therefore, during processing, the operator can place the material to be stamped on the front and rear lower dies 6 of the placement plate 5 respectively. Then, by activating the electric push rod 10, the height of the protective cover 2 can be adjusted according to the lower die 6 and the thickness of the processed material, thereby preventing the waste generated during material stamping from splashing and injuring the operator. Then, the hydraulic cylinder 21 can stamp the material on the rear lower die 6. After stamping is completed, the stamped and locked material on the lower die 6 can be ejected by the spring 18 and the push rod 8 to facilitate unloading by the operator. Then, the servo motor 20 can be activated to adjust the position of the front and rear lower dies 6 and the corresponding material, so that the operator can unload the processed material. The unloading position is far away from the upper die 22, thus preventing the hydraulic cylinder 21 from causing injury to the operator during stamping. At the same time, while unloading, the hydraulic cylinder 21 can continue to start and drive the upper die 22 to move down to continue stamping, thereby improving the efficiency of stamping and protecting the operator from injury during the operation of the stamping device.

[0025] Reference Figures 1-4 The assembly / disassembly assembly includes two knobs 9, which are rotatably connected to the front and rear walls of the placement plate 5, respectively. The output ends of both knobs 9 extend into the placement plate 5 and are fixedly connected to bevel gears 11. Bevel gears 12 mesh with the upper sides of both bevel gears 11 at a 90-degree angle. Threaded rods 13 are fixedly connected to the middle of both bevel gears 12. The upper and lower ends of the threaded rods 13 are rotatably connected to the inner wall of the placement plate 5, respectively. The lower parts of both threaded rods 13... The connection is threaded with a connecting plate 14. Both ends of the two connecting plates 14 are through a limiting rod 15. The upper and lower ends of the multiple limiting rods 15 are fixedly connected to the inner wall of the machine base 1 or the inner wall of the placement plate 5. Both ends of the two connecting plates 14 are fixedly connected with a fixing plate 16. The middle of the inner side walls of the two placement slots 7 are provided with through slots 23. The close ends of the two fixing plates 16 are through slots 23. When the fixing plate 16 is at the bottom, the top wall of the fixing plate 16 is on the same plane as the inner bottom wall of the placement slot 7.

[0026] Rotating knob 9 drives bevel gear 11 to rotate. When bevel gear 11 rotates, it drives bevel gear 12 and threaded rod 13 fixed to bevel gear 12 to rotate. When threaded rod 13 rotates, it drives connecting plate 14 to move. Since limit rods 15 pass through both ends of connecting plate 14, the limit rods 15 limit the connecting plate 14, preventing it from rotating with threaded rod 13. Thus, when threaded rod 13 rotates, connecting plate 14 can move up and down. When connecting plate 14 moves up and down, it drives fixing plates 16 on both sides to move up and down. Therefore, when installing lower mold 6, the operator can first rotate knob 9 to move fixing plate 16 to the bottom, and then insert lower mold 6 into placement groove 7 for fixation. When it is necessary to disassemble lower mold 6, simply rotate knob 9 in the opposite direction to push fixing plate 16 to move lower mold 6 upward, so that the operator can disassemble and replace lower mold 6.

[0027] Working principle: In actual use, when the stamping device stamps the lower die 6 and the material on the rear side, it pushes the ejector rod 8 down and compresses the spring 18. After stamping is completed, the ejector rod 8 can be reset under the action of the spring 18 and push the stamped material out of the lower die 6. The servo motor 20 can drive the placement plate 5 to rotate, thereby adjusting the position of the lower die 6 and the material on the front and rear sides, so that the operator can unload and replace the stamped material. At the same time, the stamping device can continue to stamp. During processing, the electric push rod 10 can also drive the protective cover 2 to move down to a suitable position, thereby protecting the operator when processing sheet metal parts of different thicknesses and preventing waste chips from flying.

[0028] In addition, when the lower mold 6 needs to be replaced, turning the knob 9 can drive the bevel gear 11 and bevel gear 12 to rotate, which in turn drives the threaded rod 13 to rotate and drives the connecting plate 14 and the fixing plate 16 to move upward. When the fixing plate 16 moves upward, the lower mold 6 can be lifted out of the placement slot 7, which makes it easier for the staff to disassemble and replace the lower mold 6.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
