Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a stamping device for aluminum profile production. Background Technology

[0002] Aluminum profiles refer to aluminum alloy profiles. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in a mold, thereby obtaining product parts with certain shapes, sizes and properties.

[0003] According to the patent document with publication number CN222288471U, a fixing component is designed to work with gears, racks, and a rotating shaft. The gears mesh with the racks, and after stamping, the gears drive the pad plate to rotate via the rotating shaft. When the pad plate rotates to a certain angle, the aluminum profile falls into the unloading chute and enters the receiving box, thus completing the unloading process. However, the pad plate has a die hole, and the stamped aluminum profile is located inside the die hole. The die hole and the surface of the pad plate are not on the same plane. Even if the pad plate is rotated for unloading, the aluminum profile will get stuck in the die hole, resulting in unsmooth unloading. Utility Model Content

The movable plate has slots at both ends, and the locking block is engaged in the slot. The locking block is hemispherical and made of rubber.

[0008] Preferably, a movable groove is horizontally formed on one side of the outer wall of the top of the worktable. A movable rod is slidably arranged in the movable groove. A moving block is fixed at the upper end of the movable rod, and a ball nut is fixed at the lower end. A threaded rod is coaxially arranged in the ball nut. A rotating groove is formed inside the worktable at a position corresponding to the threaded rod. The rotating groove and the movable groove are interconnected. The threaded rod is rotatably installed in the rotating groove, and one end of it extends to the outside of the worktable and is connected to the output end of the first servo motor.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a stamping device for aluminum profile production, including a workbench 1. A stamping die 9 is slidably installed at the top center of the workbench 1. A stamping groove is formed on the top surface of the stamping die 9. An ejector plate 21 is provided inside the stamping die 9. The ejector plate 21 is slidably installed in the stamping groove, and its size is adapted to the size of the stamping groove. In its natural state, the top surface of the ejector plate 21 is flush with the top surface of the stamping die 9. Multiple sets of automatic ejection mechanisms 20 are evenly distributed below the ejector plate 21. The automatic ejection mechanism 20 is installed inside the stamping die 9 and is an elastic telescopic mechanism. The automatic ejection mechanism 20 is compressed by the ejector plate 21 during stamping. It is used to rebound and drive the ejector plate 21 to move upward to eject material after stamping is completed.

[0023] The automatic ejector mechanism 20 includes a groove 2001 formed inside the stamping die 9, the groove 2001 communicating with the stamping groove, a telescopic rod 2002 fixedly installed at the bottom of the groove 2001, a movable plate 2004 fixedly connected to the top of the telescopic rod 2002, and a spring 2003 sleeved on the outside, the spring 2003 being fixedly connected between the bottom surface of the groove 2001 and the movable plate 2004, and a fixing rod 2005 vertically fixedly connected to the upper surface of the movable plate 2004, the upper end of the fixing rod 2005 being connected to the ejector plate 21.

[0024] Each of the two side walls of the groove 2001 is fixedly provided with a locking block 22 at the top of the corresponding position of the movable plate 2004. The movable plate 2004 has slots 2201 at both ends, and the locking block 22 is engaged in the slot 2201. The locking block 22 is hemispherical and made of rubber.

[0025] In this embodiment, in its natural state, the top surface of the top plate 21 is flush with the top surface of the stamping die 9, and the locking block 22 is engaged in the locking groove 2201. During the stamping process, the top plate 21 is subjected to pressure and moves downward, tightly abutting against the bottom of the stamping groove. When the top plate 21 moves downward, it drives the movable plate 2004 to move downward through the fixed rod 2005. During this process, the movable plate 2004 squeezes the rubber hemispherical locking block 22, and the locking block 22 deforms under force and disengages from the locking groove 2201. The movable plate 2004 moves down to compress the telescopic rod 2002 and the spring 2003. After the stamping is completed, the top plate 21 loses the external force and rebounds under the action of the spring 2003, which drives the movable plate 2004 to move up, that is, it drives the top plate 21 to return to its original position. The locking block 22 is locked into the locking groove 2201 on both sides of the movable plate 2004 to fix the position of the movable plate 2004, so that it will not move down again. The top plate 21 pushes out the aluminum profile for easy unloading.

[0026] This embodiment can realize the automatic ejection of the stamped aluminum profile. Through the set ejector plate 21 and automatic ejector mechanism 20, after the stamping is completed, the automatic ejector mechanism 20 drives the ejector plate 21 to eject the aluminum profile. Since the ejector plate 21 and the top surface of the stamping die 9 are flush, the height of the ejected aluminum profile is higher than the height of the stamping die 9, which makes it easy to remove the material after the aluminum profile is ejected.

[0027] Example 2

[0028] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 2 , Figure 4As shown, to further better realize this utility model, the following configuration is specifically adopted: In this embodiment, a movable groove 601 is horizontally opened on one side of the outer wall of the top of the workbench 1. A movable rod 6 is slidably arranged in the movable groove 601. A moving block 7 is fixedly provided at the upper end of the movable rod 6, and a ball nut 5 is fixedly provided at the lower end. A threaded rod 4 is coaxially arranged in the ball nut 5. A rotating groove 2 is opened inside the workbench 1 corresponding to the threaded rod 4. The rotating groove 2 and the movable groove 601 are interconnected. The threaded rod 4 is rotatably installed in the rotating groove 2, and one end of it extends to the outside of the workbench 1 and is connected to the output end of the first servo motor 3.

[0029] A second servo motor 8 is fixedly installed on the outer surface of the moving block 7. A first rotating shaft 18 is horizontally connected to the output end of the second servo motor 8. The first rotating shaft 18 is rotatably inserted into the moving block 7 and fixedly connected to the stamping die 9. The stamping die 9 is suspended on the worktable 1.

[0030] A second rotating shaft 19 is fixedly connected to the outer surface of the other side of the stamping die 9. A mounting plate 17 is fixedly provided on the outer wall of the top of the worktable 1 near the second rotating shaft 19. A sliding groove 2301 is horizontally opened on the mounting plate 17 at the same level as the second rotating shaft 19. A slider 23 is slidably embedded in the sliding groove 2301. The second rotating shaft 19 is rotatably installed in the slider 23.

[0031] A blanking plate 11 is welded to the edge of the worktable 1 away from the first servo motor 3. The blanking plate 11 and the stamping die 9 are located on the same central axis. A collection box 12 is attached to the bottom of the blanking plate 11.

[0032] In this embodiment, the first servo motor 3 is started, which drives the threaded rod 4 to rotate forward or backward. When the threaded rod 4 rotates, the ball nut 5 threaded on it moves left or right depending on the direction of rotation of the threaded rod 4. When the ball nut 5 moves, it drives the moving block 7 to move through the movable rod 6, which in turn drives the stamping die 9 to move through the first rotating shaft 18. The stamping die 9 then drives the slider 23 to slide in the slide groove 2301 through the second rotating shaft 19. Before stamping, the stamping die 9 is moved away from the blanking plate 1. One end of 1 moves, and then the aluminum profile is placed on the stamping die 9. Then the stamping die 9 moves back. After stamping is completed, the stamping die 9 moves toward the blanking plate 11. When the stamping die 9 moves to the blanking plate 11, the second servo motor 8 is started. The second servo motor 8 drives the stamping die 9 to rotate through the first rotating shaft 18. The stamping die 9 then drives the second rotating shaft 19 to rotate in the slider 23. After the aluminum profile is ejected, it falls onto the blanking plate 11 during the rotation of the stamping die 9, and then slides from the blanking plate 11 into the collection box 12.

[0033] Example 3

[0034] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 4 As shown, to further better realize this utility model, the following arrangement is adopted: In this embodiment, a fixing frame 13 is fixedly installed at the top center of the workbench 1. A cylinder 14 is provided at the top of the fixing frame 13. A stamping table 15 is installed on the output end of the cylinder 14. A positioning plate 16 is fixedly connected to one side of the stamping table 15. A pad 10 fixed on the workbench 1 is provided directly below the stamping table 15. The height of the pad 10 is the same as the height of the stamping die 9 suspended in the air.

[0035] In this embodiment, during stamping, the stamping die 9 is moved to the pad 10, and the cylinder 14 is activated to move the stamping table 15 downwards. However, stamping is not performed at this time. When the positioning plate 16 on the stamping table 15 can contact the stamping die 9, the cylinder 14 is closed. When the stamping die 9 contacts the positioning plate 16, it means that the stamping die 9 is directly below the stamping table 15, and stamping can be performed. The height of the pad 10 is the same as the height at which the stamping die 9 is suspended, so that the stamping die 9 is directly above the pad 10 during stamping. The pad 10 supports the stamping die 9, preventing the stamping die 9 from being stamped in a suspended state and avoiding damage to the stamping die 9.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
