Technical Field

[0001] The utility model relates to the technical field of flat panel display processing, and specifically relates to a stamping die applicable to the front frame hooks of flat panel displays. Background Technique

[0002] A flat panel display is a thin and lightweight electronic display device. Compared with the traditional cathode ray tube, it has the advantages of being thin, light, low power consumption, low radiation, no flicker, and being beneficial to human health. The front frame is an important component of the flat panel display, which is used to protect the edge of the display screen and prevent physical damage. It is mostly connected through a snap structure. During the manufacturing process of flat panel displays, the hook components of the front frame often need to be produced using stamping dies.

[0003] When the existing die is in use, the hook part is prone to getting stuck inside the lower die under the action of the applied pressure after stamping, which is not convenient for demoulding. At the same time, when the die is in use, it is necessary to manually place and fix the hook component, and then manually take it out after stamping, resulting in low processing efficiency. Therefore, a stamping die applicable to the front frame hooks of flat panel displays is proposed to solve the problems mentioned above. Content of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] Referring to Figure 2 and Figure 3 As shown, a stamping die applicable to the front frame hook of a flat panel display includes a workbench 1. A buffer groove 2 is opened in the upper right part of the workbench 1. A plurality of telescopic rods 3 are fixedly connected to the inner bottom end of the buffer groove 2. The other end of the telescopic rod 3 is fixedly connected to a lower die 4. The lower die 4 is slidably connected to the inside of the buffer groove 2. A damping spring 5 is sleeved on the outer surface of the telescopic rod 3. A stamping groove 6 is opened at the upper end of the lower die 4. The telescopic rod 3 and the damping spring 5 are arranged so that the lower die 4 can elastically move downward during stamping, which can increase the deformation path of the material during stamping, thereby reducing the impact force and vibration during stamping, helping to improve the stamping quality and extend the service life of the die.

[0025] Furthermore, a top plate 7 is slidably connected to the inside of the stamping groove 6. An installation cavity 8 is arranged inside the lower die 4. A first cylinder 9 is fixedly installed at the inner bottom end of the installation cavity 8. The output end of the first cylinder 9 penetrates through the inner top end of the installation cavity 8 and is fixedly connected to the lower end of the top plate 7. After stamping the hook part, the first cylinder 9 can push the top plate 7 upward, thereby ejecting the hook part from the inside of the stamping groove 6, facilitating demoulding.

[0026] A support frame 10 is fixedly connected to the edge of the upper right part of the workbench 1. A hydraulic cylinder 11 is fixedly installed at the upper end of the support frame 10. The output end of the hydraulic cylinder 11 penetrates through the upper end of the support frame 10 and is fixedly connected to an upper die 12. The shape of the lower end of the upper die 12 is the same as that of the stamping groove 6. The shape of the hook to be stamped is described as follows: Seen from the front of the front frame, the hook is a concave structure, and seen from the back of the front frame, it is a convex structure. Among them, the concave structure has a bottom surface parallel to the plane of the front frame and three inclined surfaces adjacent to the bottom surface, and the convex structure corresponds to the concave structure.

[0027] Furthermore, the bottom end of the upper die 12 is a horizontal plane. Among the four side surfaces of the upper die 12, one is a vertical plane, and the other three are inclined surfaces, which respectively correspond to the inclined surfaces of the hook to be stamped one by one.

[0028] Refer to Figure 1 and Figure 2 As shown in the figure, a feeding frame 13 is fixedly connected to the left side of the upper end of the workbench 1 near the lower die 4. A storage groove 14 is opened through the upper end of the feeding frame 13. An outlet 15 is opened at the lower right part of the feeding frame 13. A through groove 16 is opened at the lower left part of the feeding frame 13. A first push plate 17 is slidably connected inside the through groove 16. A second air cylinder 18 for pushing the first push plate 17 to slide is fixedly installed at the upper left part of the workbench 1.

[0029] Furthermore, the storage groove 14 is used to store the unprocessed hook components. The heights of the outlet 15 and the through groove 16 are the same as the thickness of the hook components. By pushing the first push plate 17 with the second air cylinder 18, the hook components inside the storage groove 14 can be pushed to the upper end of the lower die 4 through the outlet 15, thus realizing automatic feeding.

[0030] Refer to Figure 4 As shown in the figure, a baffle 27 is fixedly connected to the right side of the upper end of the workbench 1 near the lower die 4. Two symmetrically distributed limit blocks 26 are fixedly connected to the front and rear sides of the upper end of the lower die 4. When the first push plate 17 pushes the hook components to the upper end of the lower die 4, the baffle 27, the limit blocks 26 and the first push plate 17 can respectively limit the four side surfaces of the hook components, and can prevent the hook components from shifting during stamping.

[0031] Refer to Figure 4 and Figure 5As shown in the figure, a support plate 19 is fixedly connected to the upper end of the workbench 1 near the front side of the lower die 4. Two symmetrically distributed electric push rods 20 are fixedly installed at the front end of the support plate 19. The output end of the electric push rod 20 is fixedly connected to a second push plate 21. A material guiding plate 22 is fixedly connected to the upper end of the workbench 1 near the rear side of the lower die 4. Limiting plates 23 are fixedly connected to both the left and right sides of the material guiding plate 22. A placement groove 24 is formed at the right end of the workbench 1 near the rear side of the material guiding plate 22. A collection box 25 is slidably connected inside the placement groove 24.

[0032] Further, after the clamping member is stamped, the top plate 7 will push the hook member out of the stamping groove 6. At this time, the electric push rod 20 pushes the second push plate 21 to move, pushing the clamping member on the upper end of the top plate 7 down. The falling clamping member will slide along the material guiding plate 22 into the collection box 25, thus realizing automatic blanking and improving the processing efficiency.

[0033] Working principle: Before processing, stack the clamping members to be processed inside the material storage groove 14. During use, the first push plate 17 is pushed to move by the second cylinder 18, and the clamping members inside the material storage groove 14 are pushed through the discharge port 15 to the upper end of the lower die 4. The three sides of the clamping member are respectively in contact with the inner sides of the baffle 27 and the limiting block 26. Then, the hydraulic cylinder 11 is started to drive the upper die 12 to move downward to stamp the clamping member. During the stamping process, the telescopic rod 3 and the damping spring 5 can play a certain buffering role, reducing the impact force and vibration during stamping. After stamping, the first cylinder 9 pushes the top plate 7 upward to push the hook member out of the stamping groove 6. Then, the electric push rod 20 pushes the second push plate 21 to push the clamping member on the upper end of the top plate 7 down. The falling clamping member will slide along the surface of the material guiding plate 22 into the collection box 25. The staff can take out the processed clamping members by pulling out the collection box 25 and send them to the next processing area uniformly.
