Description

Technical Field

[0001] The utility model relates to the technical field of tools for manufacturing metal products, in particular to a limiting mechanism for bending metal products. Background Art

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products, etc. With the progress of society and the development of technology, metal products are increasingly widely used in various fields of industry, agriculture and people's lives, and also create greater value for society. Therefore, the limiting mechanism for bending metal products has become an indispensable part of production and manufacturing.

[0003] At present, when bending metal products, most of the plates are placed between the upper and lower molds without a limiting structure for the plates. In this case, the bent plates are prone to offset when the upper bending mold moves down and presses against the bent part, resulting in a reduction in bending accuracy. And when bending different positions of the plates, due to the lack of a limiting structure, it is not convenient to quickly align the positions. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a limiting mechanism for bending metal products to solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A limiting mechanism for bending metal products includes a processing table. A lower mold is installed on the top of the processing table. Two clamping plates for restricting the position of the workpiece are movably arranged on the top surface of the processing table. Mounting frames are arranged at both ends of the processing table. A control component for controlling the positions of the two clamping plates is arranged on the top of the mounting frames. The control component includes a mounting box slidably arranged on the top of the mounting frames and two connecting plates slidably arranged in a mirror image on the top of the mounting box and fixedly connected to the corresponding ends of the clamping plates. A driving component for controlling the transmission of the mounting box and the connecting plates is installed on the mounting frames and inside the mounting box.

[0007] As a further description of the above technical scheme:

[0008] The driving component includes an adjustment gear rotatably arranged on the mounting frames and a plurality of adjustment teeth fixedly arranged at the bottom of the mounting box and meshed with the adjustment gear for transmission. A first motor for controlling the rotation of the adjustment gear is installed outside the mounting frames. A bidirectional lead screw is rotatably arranged inside the mounting box. Threaded sections with opposite helix directions are arranged at both ends of the bidirectional lead screw. The corresponding bottoms of the connecting plates are movably sleeved at both ends of the bidirectional lead screw. A second motor for controlling the rotation of the bidirectional lead screw is installed at the outer end of the mounting box.

[0010] A slider is fixedly provided in the middle of the top of the mounting bracket, and a guide rod penetrating the slider is fixedly provided on the mounting box.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, by using the cooperation of the clamping plates with the control component and the driving component, the workpiece to be bent can be restricted between the two clamping plates, so that when the external upper mold presses down for bending, the workpiece will not be displaced. At the same time, the workpiece restricted within the two clamping plates can be adjusted in the bending position according to production requirements, which is convenient and fast.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1:

[0018] As Figure 1-2As shown in the figure, a limit mechanism for bending metal products includes a processing table 1. A lower mold is installed on the top of the processing table 1. Two clamping plates 3 for restricting the position of the workpiece are movably arranged on the top surface of the processing table 1. Mounting brackets 2 are provided at both ends of the processing table 1. A control component for controlling the positions of the two clamping plates 3 is provided on the top of the mounting brackets 2. The control component includes a mounting box 5 slidably arranged on the top of the mounting brackets 2 and two connecting plates 4 mirror-symmetrically slidably arranged inside the top of the mounting box 5 and fixedly connected to the ends of the corresponding clamping plates 3. A driving component for controlling the transmission of the mounting box 5 and the connecting plates 4 is installed on the mounting brackets 2 and inside the mounting box 5. By the cooperation of the clamping plates 3 with the control component and the driving component, the workpiece to be bent can be restricted between the two clamping plates 3, so that when the external upper mold presses down for bending, the workpiece will not be displaced. At the same time, the workpiece restricted between the two clamping plates 3 can adjust the bending position according to production requirements, which is convenient and fast.

[0019] Embodiment 2:

[0020] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 1-2 shown, the driving component includes an adjustment gear 7 rotatably arranged on the mounting bracket 2 and a plurality of adjustment tooth blocks 8 fixedly arranged at the bottom of the mounting box 5 and meshing with the adjustment gear 7 for transmission. A first motor for controlling the rotation of the adjustment gear 7 is installed outside the mounting bracket 2. Controlling the rotation of the first motor can drive the adjustment gear 7 to rotate, and through the meshing with the adjustment tooth blocks 8, the lateral movement of the mounting box 5 is realized, so as to realize the synchronous and same-direction movement of the two clamping plates 3, and drive the workpiece restricted between the two clamping plates 3 to move to the required bending position together. Then control the first motor to stop rotating, and then control the external lower mold to press down to realize the bending of the workpiece. The bending work of the workpiece is the prior art and will not be elaborated here. A bidirectional lead screw 6 is rotatably arranged inside the mounting box 5. Threaded sections with opposite helix directions are provided at both ends of the bidirectional lead screw 6. The bottom of the corresponding connecting plate 4 is movably sleeved at both ends of the bidirectional lead screw 6. A second motor for controlling the rotation of the bidirectional lead screw 6 is installed at the outer end of the mounting box 5. Controlling the rotation of the second motor drives the bidirectional lead screw 6 to rotate, so as to realize that the connecting plate 4 drives the corresponding clamping plate 3 to move relatively closer to fix the workpiece relatively. Then stop the rotation of the first motor, and then control the external lower mold to press down to realize the bending of the workpiece. The bending work of the workpiece is the prior art and will not be elaborated here. A slider 10 is fixedly arranged in the middle of the top of the mounting bracket 2. A guide rod 9 penetrating the slider 10 is fixedly arranged on the mounting box 5. The cooperation of the slider 10 and the guide rod 9 is used to realize the stable lateral sliding of the mounting box 5 on the mounting bracket 2.
