Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, and in particular to an auxiliary fixing mechanism for sheet metal bending. Background Technology

[0002] In the field of sheet metal processing, sheet metal bending is a common processing procedure. During the bending process, the stability and precise positioning of the sheet metal directly affect the processing quality and efficiency.

[0003] Traditional sheet metal bending auxiliary fixing mechanisms have many shortcomings. For example, when fixing sheet metal manually by rotating and pressing with threads, the operation is not only cumbersome and labor-intensive, but also time-consuming due to repeated adjustments, which seriously affects the efficiency of sheet metal processing. At the same time, for sheet metal of different lengths, traditional mechanisms lack effective limiting devices, making it difficult to accurately keep the sheet metal in the center of the processing table. This can easily lead to positional deviation of the sheet metal during bending, resulting in defective products. In addition, traditional fixing methods rely heavily on manual experience, have low automation, and cannot meet the needs of large-scale, high-precision modern sheet metal processing. Therefore, this application provides an auxiliary fixing mechanism for sheet metal bending to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary fixing mechanism for sheet metal bending, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An auxiliary fixing mechanism for sheet metal bending includes a support platform, a processing table fixedly connected to the top center of the support platform, an extrusion groove on the top of the processing table, and movable grooves on the top of the support platform near both sides of the processing table; a fixing component for clamping and fixing both sides of the sheet metal, the fixing component being connected to the processing table; and a limiting component for keeping sheet metal of different lengths at the center, the limiting component being connected to the support platform.

[0007] Optionally, the fixing component is used to fix an electric push rod to the side of the processing table. A lower clamping plate is fixedly connected to the top of the electric push rod, and a connecting rod A is fixedly connected to the bottom of the lower clamping plate. The connecting rod A is slidably connected to the processing table. A connecting rod B is slidably connected to the side of the processing table, and an upper clamping plate is fixedly connected to one end of the connecting rod B that passes through the lower clamping plate.

[0008] Optionally, the connecting rod A is fixedly connected to the outer side of the connecting rod A, the connecting rod B is fixedly connected to the outer side of the connecting rod B, and a transmission gear is rotatably connected between the rack A and the rack B on the side of the processing table.

[0009] Optionally, the transmission gear is characterized in that it is meshed with rack A and rack B respectively.

[0010] Optionally, the limiting component includes a bidirectional threaded rod rotatably connected to the inner side of the moving groove, a moving rod threadedly connected to the outer side of the bidirectional threaded rod, a sliding rod slidably connected to the top of the moving rod, and a limiting plate fixedly connected to the end of the sliding rod near the processing table.

[0011] Optionally, the bidirectional threaded rod extension support platform has a rotating wheel fixedly connected to one end of its outer side, and a return spring is fixedly connected between the limiting plate and the moving rod.

[0012] Optionally, the support platform is characterized in that a mounting bracket is fixedly connected to one side near the electric push rod, a cylinder is fixedly connected to the top of the mounting bracket, a pressing block is fixedly connected to the end of the cylinder, and the pressing block is slidably connected to the mounting bracket.

[0013] Beneficial effects:

[0014] In the above solution, by setting a fixing component, the lower clamping plate is driven to move up by an electric push rod, and the upper clamping plate is driven to move down synchronously by the meshing transmission of the rack and pinion gears, thus achieving bidirectional clamping of both sides of the sheet metal. This method is different from the traditional manual threaded rotation and extrusion fixing method, avoiding the tedious process of repeated manual operation, reducing labor intensity, and improving clamping efficiency through mechanical synchronous transmission, reducing the time spent fixing the sheet metal, saving time for subsequent bending processing, and effectively avoiding the problem of affecting the overall processing progress due to the inefficiency of manual operation.

[0015] By setting a limiting component, rotating the wheel drives the bidirectional threaded rod to rotate, causing the limiting plates on the two sets of moving rods to come close to both ends of the sheet metal. With the elastic action of the sliding rod and the return spring, it can adapt to sheet metal of different lengths and automatically position it to the center of the top of the processing table. This solves the problem of positional offset caused by differences in sheet metal length in traditional processing, ensures the accuracy of bending position, reduces defective products caused by positioning deviation, and achieves universal limiting through mechanical structure, eliminating the need for repeated adjustments for different sheet metal specifications, further improving processing efficiency and finished product qualification rate.

[0022] 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.

[0023] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides an auxiliary fixing mechanism for sheet metal bending, including a support platform 1, a processing table 5 fixedly connected to the center of the top of the support platform 1, an extrusion groove 8 on the top of the processing table 5, and moving grooves 9 on both sides of the top of the support platform 1 near the processing table 5, a fixing component 6 for clamping and fixing the two sides of the sheet metal, the fixing component 6 being connected to the processing table 5, and a limiting component 7 for keeping sheet metal of different lengths at the center, the limiting component 7 being connected to the support platform 1, and a mounting bracket 2 fixedly connected to one side of the support platform 1 near the electric push rod 601, with a cylinder 3 fixedly connected to the top of the mounting bracket 2, and the cylinder 3 having a... The part is fixedly connected to the extrusion block 4, and the extrusion block 4 is slidably connected to the mounting bracket 2. The auxiliary fixing mechanism for sheet metal bending provided in this application can not only use the electric push rod 601 to drive the lower clamping plate 602 and the upper clamping plate 608 to clamp the sheet metal on both sides simultaneously when fixing, so that the height of the sheet metal position can be fixed, avoiding the traditional manual repeated thread rotation and extrusion fixing, which is labor-intensive, cumbersome and affects the efficiency of sheet metal processing. At the same time, the limiting component 7 is used to limit the sheet metal of different lengths, so that the sheet metal position is always kept at the center of the top of the processing table 5, improving the accuracy of sheet metal bending and avoiding position deviation, which will result in defective products.

[0024] In this embodiment, as Figures 1 to 3 As shown, the fixing component 6 is used to fix the electric push rod 601 to the side of the processing table 5. The top of the electric push rod 601 is fixedly connected to the lower clamping plate 602, and the bottom of the lower clamping plate 602 is fixedly connected to the connecting rod A603. The connecting rod A603 is slidably connected to the processing table 5. The side of the processing table 5 is slidably connected to the connecting rod B606. The end of the connecting rod B606 that passes through the lower clamping plate 602 is fixedly connected to the upper clamping plate 608. The outer side of the connecting rod A603 is fixedly connected to the rack A604, and the outer side of the connecting rod B606 is fixedly connected to the rack B607. The side of the processing table 5 is rotatably connected to the rack A604 and the rack B607. The transmission gear 605 is respectively connected to the rack A604. The upper clamping plate 608 is meshed with the rack B607. When the sheet metal needs to be fixed, the electric push rod 601 is activated, causing the lower clamping plate 602 to move upward. When the lower clamping plate 602 moves upward, it simultaneously causes the rack A604 on the connecting rod A603 to move upward, so that the rack A604 meshes with the transmission gear 605, thereby causing the transmission gear 605 to mesh and rotate with the rack B607. The rack B607 then causes the connecting rod B606 to move downward along the inner side of the processing table 5, so that the upper clamping plate 608 and the lower clamping plate 602 move synchronously relative to each other, clamping and fixing the sheet metal. This avoids the traditional manual repeated threading and squeezing fixing, which is labor-intensive, cumbersome, and affects the efficiency of sheet metal processing.

[0025] In this embodiment, as Figures 4 to 5 As shown, the limiting assembly 7 includes a bidirectional threaded rod 701 rotatably connected to the inner side of the moving groove 9. A moving rod 703 is threadedly connected to the outer side of the bidirectional threaded rod 701. A sliding rod 704 is slidably connected to the top of the moving rod 703. A return spring 706 is fixedly connected to one end of the sliding rod 704 near the processing table 5. A rotating wheel 702 is fixedly connected to one end of the bidirectional threaded rod 701 extending to the outer side of the support table 1. The return spring 706 is fixedly connected between the limiting plate 705 and the moving rod 703. In use, by placing the sheet metal... On the lower clamping plate 602, by rotating the rotating wheel 702, the two sets of moving rods 703 on the bidirectional threaded rod 701 move closer to each other along the moving groove 9, so that the limiting plate 705 is close to both ends of the sheet metal, and the sliding rod 704 moves outward along the moving rod 703. The return spring 706 is used to initially limit the position of the sheet metal of different lengths, so that the sheet metal is kept at the center of the top of the processing table 5, improving the accuracy of sheet metal bending, facilitating bending, avoiding positional deviation, and causing defective products.

[0026] The working principle of the technical solution provided by this utility model is as follows: In use, the sheet metal is placed on the lower clamping plate 602. By rotating the rotating wheel 702, the two sets of moving rods 703 on the bidirectional threaded rod 701 move closer to each other along the moving groove 9, so that the limiting plate 705 is close to both ends of the sheet metal. This causes the sliding rod 704 to move outward along the moving rod 703. The return spring 706 is used to initially limit the position of the sheet metal of different lengths, so that the sheet metal is kept at the center of the top of the processing table 5, improving the accuracy of sheet metal bending, facilitating bending, and avoiding positional deviation that could result in defective products. When it is necessary to fix the sheet metal, the electric push rod 601 is activated, causing the electric push rod 601 to drive the lower clamping plate 602 to move towards the center of the processing table 5. As the lower clamping plate 602 moves upward, it simultaneously drives the upper rack A604 of the connecting rod A603 to move upward, causing the rack A604 to mesh with the transmission gear 605. This, in turn, causes the transmission gear 605 to mesh and rotate with the rack B607, allowing the rack B607 to drive the connecting rod B606 to move downward along the inner side of the processing table 5. This causes the upper clamping plate 608 and the lower clamping plate 602 to move synchronously relative to each other, clamping and fixing the sheet metal. This avoids the traditional method of repeated threaded rotation and pressing for fixing, which is labor-intensive, cumbersome, and affects the efficiency of sheet metal processing. Afterward, the cylinder 3 is activated, causing the pressing block 4 to move downward, so that the sheet metal is pressed against the inner side of the pressing groove 8 at the top of the processing table 5, achieving the bending process of the sheet metal.
