[0020] 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.

[0021] Please refer to Figures 1 to 5. In this embodiment of the present invention, a stamping device for processing aluminum single panels includes a top plate 1. A hydraulic push cylinder 2 is installed on the top of the top plate 1. Guide rods 4 extending downward are integrally formed at the four corners of the bottom end of the top plate 1. The bottom ends of the guide rods 4 are connected to a support base 5. A sliding plate 3 is slidably connected to the outer wall of the guide rods 4. A first spring 6, which is sleeved with the guide rod 4, is fixedly connected between the guide rod 4 and the support base 5. The bottom end of the piston rod of the hydraulic push cylinder 2 passes through the top plate 1 and is connected to the top of the sliding plate 3. The support base 5 is equipped with a lower mold mechanism. The bottom end of the sliding plate 3 is integrally formed with a downward protruding upper mold 20. The back end of the top plate 1 and the back end of the support base 5 are equipped with an ejection mechanism. The back end of the guide rod 4 is fixedly equipped with a fixing rod 11. One end of the fixing rod 11 is rotatably equipped with a pressing wheel 12 that abuts against the ejection mechanism. The top three sides of the support base 5 are distributed with limiting blocks 19 that limit the three sides of the workpiece 13. The bottom end of the sliding plate 3 is provided with three receiving grooves 23 that are aligned with the three limiting blocks 19 in the vertical direction.

[0022] In this embodiment: First, the workpiece 13, which has been cut and punched at the four corners, is placed on the top of the lower mold mechanism until three sides of the workpiece 13 abut against the three limit blocks 19. Then, the hydraulic push cylinder 2 is activated. The hydraulic push cylinder 2 extends and pushes the sliding plate 3 to slide down along the guide rod 4. At this time, the first spring 6 is compressed. The sliding plate 3, which moves downward, drives the extrusion wheel 12 to move downward synchronously through the fixed rod 11, extruding the ejection mechanism and pushing the ejection mechanism outward to avoid the ejection mechanism interfering with the downward movement of the sliding plate 3. The sliding plate 3 drives the upper mold 20 to press on the top of the workpiece. The upper mold 20 presses down on the workpiece 13. At this time, the lower mold mechanism moves downward under force, while the support seat 5 remains stationary. At this time, the edge of the workpiece 13 is bent at ninety degrees under the limit.

[0023] After the workpiece 13 is bent, the hydraulic push cylinder 2 is reset. At this time, the sliding plate 3 is reset upwards in sync. The upward-reset sliding plate 3 drives the extrusion wheel 12 to move upwards in sync through the fixed rod 11. At this time, the ejection mechanism is reset. During the reset process, the ejection mechanism pushes the bent workpiece outwards.

[0024] Please refer to Figures 1 and 2. The ejection mechanism includes a sliding shaft 7 fixedly installed on the back end of the top plate 1 and a fixed seat 8 fixedly installed on the back end of the support seat 5. A pressure plate 9 is slidably installed on the outer wall of the sliding shaft 7. A pressure inclined surface 10 is formed in the middle of the pressure plate 9. The ejection mechanism also includes a push rod 14 fixedly installed below the end of the pressure plate 9 near the top plate 1. The push rod 14 is slidably connected to the fixed seat 8. An "L"-shaped push plate 15 is fixedly installed at the end of the push rod 14 away from the pressure plate 9. The push rod 14 is fixedly connected to the vertical plate of the push plate 15. A fixing ring 16 is fixedly installed on the outer wall of the push rod 14. A second spring 17 is fixedly installed between the fixing ring 16 and the fixed seat 8. The vertical plate of the push plate 15 is located on the top of the workpiece 13, which is in a planar state.

[0025] In this embodiment: During the downward movement of the extrusion roller 12, the extrusion roller 12 applies extrusion force to the pressure inclined surface 10. At this time, the pressure plate 9 moves away from the top plate 1 along the outer wall of the sliding shaft 7. When the pressure plate 9 moves, it drives the push rod 14 to move synchronously. At this time, the second spring 17 is compressed by the fixing ring 16. At the same time, the push rod 14 drives the push plate 15 to move outward and gradually misaligns with the top of the support seat 5.

[0026] During the upward movement of the extrusion roller 12, the second spring 17 is reset. The reset second spring 17 pushes the fixed ring 16 to reset. At this time, the push rod 14 pushes the push plate 15 to reset. The push plate 15 can then push the workpiece 13, which is bent upward at ninety degrees on all four sides, outward.

[0027] When stamping and bending the next workpiece 13, the workpiece 13 is placed on the top of the lower mold mechanism again. Since the distance between the bottom of the vertical plate of the push plate 15 and the support base 5 is greater than the thickness of the workpiece 13 in the flat state, the push plate 15 will not obstruct the placement of the workpiece 13.

[0028] Please refer to Figures 3 and 4 for details. The lower mold mechanism includes a lower mold 18 that is slidably connected to the inner cavity of the support base 5. Slide rods 21 that pass through to the bottom of the support base 5 are fixedly installed at the four corners of the bottom end of the lower mold 18. A No. 3 spring 22 that is sleeved with the slide rod 21 is fixedly installed between the bottom end of the lower mold 18 and the inner wall of the support base 5.

[0029] In this embodiment: after the upper mold 20 contacts the top of the workpiece 13, the workpiece 13 is subjected to force and transmits the downward pressure to the lower mold 18. At this time, the lower mold 18 is subjected to force and moves downward, pushing the slide bar 21 to slide downward. At this time, the third spring 22 moves downward, and the pressed part of the workpiece 13 moves downward synchronously, while the four edges of the unpressed workpiece 13 are raised upward under the limit of the support seat 5 until they are bent at ninety degrees. When the upper mold 20 is reset, the third spring 22 is reset synchronously. The reset third spring 22 pushes the lower mold 18 to reset, and the reset lower mold 18 pushes the bent workpiece to reset.

[0030] It should be noted that since the lower part of the pressure plate 9 is a vertical structure, the pushing mechanism remains stationary during the initial upward movement of the upper die 20 until the extrusion wheel 12 contacts the pressure inclined surface 10, at which point it will begin to reset. At this time, the upper die 20 is already above the support base 5, so there will be no interference phenomenon where the pushing mechanism has already started to move and moved above the workpiece 13 before the workpiece 13 has been reset.

[0031] Please refer to Figures 3 and 4 for details. The cross-section of the upper mold 20 is smaller than that of the lower mold 18.

[0032] In this embodiment: This design allows for a movable gap between the upper mold 20 and the inner wall of the support base 5, which allows the workpiece 13 to be bent and deformed.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
