[0003] The top and back plates are generally arc-shaped, making bending them cumbersome. Existing equipment often requires manual loading or unloading during bending, which can easily cause injury to workers and is also quite troublesome. Therefore, an automatic bending device for top and back plates with convenient pushing and loading functions is designed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic bending device for top and rear plates, which has the advantages of easy material pushing and loading. It solves the problem that the top and rear plates are generally arc-shaped, making bending operations cumbersome. Existing equipment often requires manual loading or unloading during bending, which can easily cause injury to workers and is also cumbersome to operate.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned purpose of facilitating material pushing and loading, this utility model provides the following technical solution: an automatic bending device for a top and rear plate, comprising a support frame and a placement platform installed on the upper side of the support frame, wherein a support base is installed on one side of the placement platform, a lower pressing mold is installed on the upper side of the support base, and side columns are respectively installed on both sides of the support base, a top frame is fixedly installed at the top of the side columns, and a hydraulic cylinder is installed on the upper side of the top frame, an upper pressing mold is installed at the output end of the hydraulic cylinder, and the upper pressing mold is positioned above the lower pressing mold, a placement block is fixedly installed on the upper side of the placement platform, and conveyor belts are respectively installed on both sides of the placement block, a support column is installed on one side of the support base, and a push plate is installed on the inner side of the support column. The top and rear plate is placed above the placement block, ensuring full contact with the conveyor belt. The conveyor belt transports it to the upper side of the lower pressing mold. The lower pressing mold is an arc-shaped convex mold, which can be customized according to the actual shape of the top and rear plate. The hydraulic cylinder drives the upper pressing mold to move vertically below the top frame, bending the rear top plate to make its shape correspond to the mold. After bending, it is pushed out of the upper side of the lower pressing mold by the push plate, pushing it above the placement block and ensuring full contact with the conveyor belt, so that the conveyor belt moves the top and rear plate out.

[0008] Preferably, drive wheels are installed on both sides of the placement block, and the drive wheels are rotatably connected to the outer side of the placement block. The conveyor belt is installed on the outer side of the drive wheels, and rubber protrusions are fixedly installed on the outer side of the conveyor belt. The drive wheels and the conveyor belt cooperate with each other. The drive wheels are installed on both sides of the placement block, and there are two drive wheels on each side. The conveyor belt is installed on the outer side of the drive wheels. The friction between the inner wall of the conveyor belt and the outer side of the drive wheels is sufficient to ensure normal operation of both. The rubber protrusions are used to increase the friction between the conveyor belt and the lower side of the top and rear plates, so that it can be properly conveyed into the mold.

[0009] Preferably, a connecting shaft is installed on the inner wall of the placement block, and one end of the connecting shaft passes through the inner wall of the placement block and is fixedly connected to one end of the transmission wheel. A bidirectional motor is installed inside the placement block, and one end of the connecting shaft is connected to the output end of the bidirectional motor. The bidirectional motor is located at one end inside the placement block, and both ends of the bidirectional motor are output ends, which are fixedly connected to the connecting shafts at corresponding positions. The bidirectional motor drives the connecting shafts at both ends to rotate, which in turn drives the transmission wheels on both sides of the outer side of the placement block to rotate, so that the conveyor belt can operate normally and drive the loading and unloading of the top and rear plates.

[0010] Preferably, a pneumatic cylinder is installed inside the support column, and the output end of the pneumatic cylinder extends through one side of the support column. The output end of the pneumatic cylinder is located below the upper pressing die, and a push plate is fixedly installed on the output end of the pneumatic cylinder. When the top and rear plates are bent, the pneumatic cylinder drives the push plate to move inside the support column, allowing it to extend out of the support column and push the top and rear plates on one side, enabling them to move away from the upper side of the lower pressing die and move to the upper side of the conveyor belt, which then transports them back.

[0011] Preferably, telescopic blocks are installed on both sides of the support base, with the upper end of the telescopic blocks positioned directly below the two ends of the upper pressing mold. A buffer spring is installed inside the telescopic block, and a damper is installed inside the buffer spring. The two ends of the upper pressing mold do not contact the upper side of the lower pressing mold, but the interiors of the lower and upper pressing molds can overlap. The telescopic blocks contact the two ends of the upper pressing mold, causing the telescopic blocks to compress and overlap the lower and upper pressing molds when the upper pressing mold moves vertically. The buffer springs inside the telescopic blocks increase the buffering force, stabilizing the upper pressing mold, and the dampers prevent the buffer springs and telescopic blocks from rebounding rapidly.

[0012] Preferably, a sliding plate is fixedly installed on one side of the side column, and the sliding plate is engaged with the inner walls of both ends of the upper pressing mold. The sliding plate is slidably connected to one end of the upper pressing mold, and the lower end of the sliding plate is located at the upper end of the telescopic block. The sliding plate on one side of the side column passes through both ends of the upper pressing mold, so that it can be engaged between the two side columns and restrict the movement direction of the upper pressing mold, so that it will not deviate from the track and can fully engage with the lower pressing mold.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an automatic bending device for the top and rear plates, which has the following advantages: This automatic bending device for the top and rear plates places the top and rear plates above the placement block, so that they are in full contact with the conveyor belt. The conveyor belt transports them to the upper side of the lower pressing mold. Then, the hydraulic cylinder drives the upper pressing mold to move vertically below the top frame, so that it performs a bending operation on the rear top plate, making its shape correspond to the mold. After bending, the plate pushes it out of the upper side of the lower pressing mold, so that it is pushed above the placement block and in full contact with the conveyor belt, so that the conveyor belt moves the top and rear plates out, thereby achieving the effect of facilitating material pushing and loading.

[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] Example: Please refer to Figure 1-5 An automatic bending device for a top and back panel includes a support frame 1 and a placement platform 2 installed on the upper side of the support frame 1. A support base 3 is installed on one side of the placement platform 2. A lower pressing mold 4 is installed on the upper side of the support base 3. Side columns 5 are installed on both sides of the support base 3. A top frame 10 is fixedly installed on the top of the side columns 5. A hydraulic cylinder 11 is installed on the upper side of the top frame 10. An upper pressing mold 9 is installed at the output end of the hydraulic cylinder 11. The upper pressing mold 9 is positioned above the lower pressing mold 4. A placement block 7 is fixedly installed on the upper side of the placement platform 2. Conveyor belts 8 are installed on both sides of the placement block 7. A support column 12 is installed on one side of the support base 3. A push plate 15 is installed on the inner side of the support column 12.

[0023] The top and rear plate is placed above the placement block 7, making it fully contact with the conveyor belt 8. The conveyor belt 8 transports it to the upper side of the lower pressing mold 4. The lower pressing mold 4 is an arc-shaped convex mold, which can be customized according to the actual shape of the top and rear plate. The hydraulic cylinder 11 drives the upper pressing mold 9 to move vertically below the top frame 10, so that it performs a bending operation on the rear top plate, making its shape correspond to the mold. After bending, it is pushed out of the upper side of the lower pressing mold 4 by the push plate 15, so that it is pushed above the placement block 7 and makes full contact with the conveyor belt 8, so that the conveyor belt 8 moves the top and rear plate out.

[0024] Drive wheels 17 are installed on both sides of the placement block 7, and the drive wheels 17 are rotatably connected to the outer side of the placement block 7. The conveyor belt 8 is installed on the outer side of the drive wheels 17, and rubber protrusions 20 are fixedly installed on the outer side of the conveyor belt 8.

[0025] The drive wheel 17 and the conveyor belt 8 are used together. The drive wheel 17 is installed on both sides of the placement block 7, and there are two drive wheels 17 on each side. The conveyor belt 8 is installed on the outside of the drive wheel 17. The friction between the inner wall of the conveyor belt 8 and the outer side of the drive wheel 17 is sufficient to enable both to operate normally. The rubber protrusion 20 is used to increase the friction between the conveyor belt 8 and the lower side of the top and rear plate so that it can be normally conveyed into the mold.

[0026] A connecting shaft 19 is installed on the inner wall of the placement block 7, and one end of the connecting shaft 19 passes through the inner wall of the placement block 7 and is fixedly connected to one end of the transmission wheel 17. A bidirectional motor 18 is installed inside the placement block 7, and one end of the connecting shaft 19 is connected to the output end of the bidirectional motor 18.

[0027] The bidirectional motor 18 is located at one end inside the placement block 7. Both ends of the bidirectional motor 18 are output ends and are fixedly connected to the connecting shaft 19 at the corresponding positions. The bidirectional motor 18 drives the connecting shaft 19 at both ends to rotate, which in turn drives the transmission wheels 17 on both sides of the outer side of the placement block 7 to rotate, so that the conveyor belt 8 can operate normally and drive the top and rear plates to load and unload.

[0028] A pneumatic cylinder 16 is installed inside the support column 12, and the output end of the pneumatic cylinder 16 passes through one side of the support column 12. The output end of the pneumatic cylinder 16 is located below the upper pressing mold 9, and the push plate 15 is fixedly installed on the output end of the pneumatic cylinder 16.

[0029] When the top and back plate is bent, the pneumatic cylinder 16 drives the push plate 15 to move inside the support column 12, so that it can extend out of the support column 12 and push the top and back plate on one side, so that it can leave the upper side of the lower die 4 and move the top and back plate to the upper side of the conveyor belt 8, and the conveyor belt 8 transports it back.

[0030] Telescopic blocks 6 are installed on both sides of the support base 3, and the upper end of the telescopic block 6 is located directly below both ends of the upper pressure mold 9. A buffer spring 13 is installed inside the telescopic block 6, and a damper is installed inside the buffer spring 13.

[0031] The upper pressing mold 9 has two ends that do not contact the upper side of the lower pressing mold 4. The interiors of the lower pressing mold 4 and the upper pressing mold 9 can overlap. The telescopic block 6 contacts both ends of the upper pressing mold 9, so that when the upper pressing mold 9 moves vertically, the telescopic block 6 will be compressed, and the lower pressing mold 4 will overlap with the upper pressing mold 9. The buffer spring 13 inside the telescopic block 6 can increase the buffering force of the telescopic block 6, so that the upper pressing mold 9 plays a stabilizing role. The damper can prevent the buffer spring 13 and the telescopic block 6 from rebounding quickly.

[0032] A sliding plate 14 is fixedly installed on one side of the side column 5, and the sliding plate 14 is snapped into the inner wall of both ends of the upper pressing mold 9. The sliding plate 14 is slidably connected to one end of the upper pressing mold 9, and the lower end of the sliding plate 14 is set at the upper end of the telescopic block 6.

[0033] Among them, the sliding plate 14 on one side of the side column 5 passes through both ends of the upper pressing mold 9, so that it can be locked between the two side columns 5 and restrict the movement direction of the upper pressing mold 9 so that it will not deviate from the track and can be fully combined with the lower pressing mold 4.

[0034] Working principle: The top and rear plate is placed above the placement block 7, making it fully contact the conveyor belt 8. The bidirectional motor 18 drives the connecting shafts 19 at both ends to rotate, which in turn drives the transmission wheels 17 on both sides of the outer side of the placement block 7 to rotate, so that the conveyor belt 8 can operate normally and drive the top and rear plate to load and unload. The conveyor belt 8 transports it to the upper side of the lower pressing mold 4. The lower pressing mold 4 is an arc-shaped convex mold. The hydraulic cylinder 11 drives the upper pressing mold 9 to move vertically below the top frame 10, so that it performs a bending operation on the rear top plate, making its shape correspond to the mold. After bending, the pneumatic cylinder 16 drives the push plate 15 to move inside the support column 12, so that it can extend out of the support column 12 and push the top and rear plate on one side, so that it can leave the upper side of the lower pressing mold 4 and move the top and rear plate to the upper side of the conveyor belt 8, so that the conveyor belt 8 moves the top and rear plate out.

[0035] 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.
