A threaded rod is threadedly connected to one side of the mounting frame, and an adjusting turntable is fixedly connected to one side of the threaded rod. This invention allows for folding and unfolding, thus supporting the sheet metal to be processed, preventing deformation that could affect the sheet metal bending effect, and is also convenient to carry.

[0004] However, in actual use, the bending device is cumbersome to adjust the overall extension and retraction, and it is also slow to bend the metal sheet. Furthermore, the lower support plate cannot be adjusted according to the bending angle of the metal sheet. Therefore, improving and perfecting the above-mentioned problems is an urgent issue to be addressed. Utility Model Content

[0005] The purpose of this utility model is to provide a portable bending device for sheet metal processing, in order to solve the problems mentioned in the background art, such as the cumbersome overall extension and retraction adjustment of the bending device, the slow efficiency when bending thin metal sheets, and the inability of the lower support plate to be adjusted according to the bending angle of the thin metal sheet.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable sheet metal bending device, comprising a mounting plate, a first side plate fixedly connected to the top surface of the mounting plate, a first support roller mounted on the back of the first side plate, and a first telescopic frame and a second telescopic frame fixedly connected from front to back on the right side surface of the mounting plate, wherein the first telescopic frame has a telescopic groove inside.

[0007] The telescopic frame is installed inside the telescopic groove. A second hole is opened on the front surface of the telescopic frame, and a first hole is opened on the front surface of the first telescopic frame. A locking post is installed inside the first hole. The locking post is compatible with the first hole and the second hole. A stabilizing block is fixedly connected to the right side of the telescopic frame.

[0008] Preferably, a connecting block is fixedly connected to the upper surface of the stabilizing block, and a positioning plate is fixedly connected to the top surface of the connecting block.

[0009] Preferably, a top block is fixedly connected to the back of the positioning plate, a cylinder body is fixedly connected to the top surface of the top block, and a bending frame is installed through the interior of the top block at the output end of the cylinder body.

[0010] Preferably, a limiting frame is installed on the top surface of both the second telescopic frame and the first telescopic frame, and a limiting cylinder is installed on the inner side wall of the limiting frame.

[0011] Preferably, a second support roller is mounted on the back of the connecting block, and the second support roller is horizontally positioned relative to the first support roller.

[0012] Preferably, a drive motor is installed inside the stabilizing block, and a rotating column is installed at the output end of the drive motor.

[0013] Preferably, a rotating cylinder is mounted on the outer surface of the rotating column, and a support block is fixedly connected to the outer surface of the rotating cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This portable sheet metal bending device, through its mounting plate, first side plate, first telescopic frame, second telescopic frame, telescopic groove, telescopic frame, first hole, second hole, locking post, and stabilizing block, allows for easy adjustment of the distance between the mounting plate and the stabilizing block. The telescopic frame is moved to the appropriate position within the telescopic groove, aligning the first and second holes. Four sets of first holes and six sets of second holes are provided to move the telescopic frame to the desired position. Once the first and second holes overlap, the locking post is installed inside them, locking the telescopic frame in place. This provides a good overall locking effect and makes adjusting the distance between the mounting plate and the stabilizing block convenient, demonstrating the practicality of the design.

[0016] 2. This portable sheet metal bending device, through the configuration of a connecting block, a second support roller, a positioning plate, a top block, a cylinder body, a bending frame, a limiting frame, a limiting cylinder, a rotating column, a rotating cylinder, and a drive motor, first places the thin sheet on the top surface of the first and second support rollers for conveying. Simultaneously, the thin sheet passes through the interior of the limiting frame, where the limiting cylinder supports its position, resulting in stable support during bending. Then, by activating the cylinder body, the bending frame moves downwards to contact the thin sheet, ensuring good overall contact and enabling bending. Before bending, the drive motor rotates the rotating column and rotating cylinder, adjusting the support block to a suitable angle for bending the sheet. Therefore, the bending angle of the thin sheet can be adjusted by changing the angle of the support block, demonstrating the device's functionality. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-5 One embodiment provided by this utility model:

[0025] A portable sheet metal bending device is disclosed. The cylinder body 14 and drive motor 20 used in this application are commercially available products, and their principles and connection methods are well-known prior art and will not be elaborated upon here. The device includes a mounting plate 1, with a first side plate 2 fixedly connected to its top surface. A first support roller 3 is mounted on the back of the first side plate 2. A first telescopic frame 4 and a second telescopic frame 5 are fixedly connected sequentially from front to back on the right side surface of the mounting plate 1. A telescopic groove 6 is provided inside the first telescopic frame 4. Limiting frames 16 are mounted on the top surfaces of both the second telescopic frame 5 and the first telescopic frame 4. Limiting cylinders 17 are mounted on the inner side walls of the limiting frames 16. A second support roller 23 is mounted on the back of the connecting block 22. The second support roller 23 and the first support roller 3 are horizontally positioned relative to each other. First, the thin plate is placed on the top surface of the first support roller 3 and the second support roller 23 for conveying. At the same time, the thin plate also passes through the inside of the limiting frame 16. The limiting cylinder 17 supports the position of the thin plate, so that the support effect of the thin plate is relatively stable during bending. Then, the cylinder body 14 is started, and the cylinder body 14 drives the bending frame 15 to move downward to abut against the thin plate, so that the overall abutment effect is good, and the thin plate can be bent. Before bending the thin plate, the drive motor 20 is started, and the drive motor 20 drives the rotating column 18 and the rotating cylinder 19 to rotate, so that the support block 21 can be adjusted to a suitable angle to bend the thin plate that needs to be bent. Therefore, the bending angle of the thin plate can also be adjusted by adjusting the angle of the support block 21.

[0026] Telescopic frame 7 is installed inside telescopic groove 6. A second hole 9 is formed on the front surface of telescopic frame 7. A first hole 8 is formed on the front surface of first telescopic frame 4. A locking pin 10 is installed inside the first hole 8. The locking pin 10 is compatible with the first hole 8 and the second hole 9. A stabilizing block 11 is fixedly connected to the right side of telescopic frame 7. A connecting block 22 is fixedly connected to the upper surface of stabilizing block 11. A positioning plate 12 is fixedly connected to the top surface of connecting block 22. A top block 13 is fixedly connected to the back of positioning plate 12. A cylinder body 14 is fixedly connected to the top surface of top block 13. A bending frame 15 is installed inside top block 13 through the output end of cylinder body 14. A drive motor 20 is installed inside stabilizing block 11. A rotating column 18 is installed at the output end of drive motor 20. A rotating cylinder 19 is installed on the outer surface of the rotating column 18, and a support block 21 is fixedly connected to the outer surface of the rotating cylinder 19. When it is necessary to adjust the distance between the mounting plate 1 and the stabilizing block 11, the telescopic frame 7 is moved to a suitable position inside the telescopic groove 6, and the first hole 8 and the second hole 9 are aligned. There are four sets of the first hole 8 and six sets of the second hole 9, which can move the telescopic frame 7 to a suitable position. Then, when the positions of the first hole 8 and the second hole 9 overlap, the locking column 10 is installed inside the first hole 8 and the second hole 9, thereby locking the position of the telescopic frame 7. The overall locking effect is good, so the operation is more convenient when adjusting the distance between the mounting plate 1 and the stabilizing block 11.

[0027] Working principle: When the operator uses this device, first connect the device to an external power source to provide power support. When it is necessary to adjust the distance between the mounting plate 1 and the stabilizing block 11, move the telescopic frame 7 to the appropriate position inside the telescopic groove 6, and align the first hole 8 and the second hole 9. There are four sets of first holes 8 and six sets of second holes 9, which can move the telescopic frame 7 to the appropriate position. Then, when the positions of the first hole 8 and the second hole 9 overlap, install the locking pin 10 inside the first hole 8 and the second hole 9 to lock the position of the telescopic frame 7.

[0028] The thin plate is placed on the top surface of the first support roller 3 and the second support roller 23 for conveying. At the same time, the thin plate also passes through the inside of the limiting frame 16. The limiting cylinder 17 supports the position of the thin plate, so that the support effect of the thin plate is relatively stable during bending. Then, the cylinder body 14 is started, which drives the bending frame 15 to move downward to abut against the thin plate, so that the overall abutment effect is good, and the thin plate can be bent. Before bending the thin plate, the drive motor 20 is started, which drives the rotating column 18 and the rotating cylinder 19 to rotate, so that the support block 21 can be adjusted to a suitable angle to bend the thin plate to be bent. Therefore, the working principle of this utility model can be achieved by adjusting the angle of the support block 21.
