Description

Technical Field

[0001] This utility model belongs to the technical field of steel plate edge rolling tooling, and particularly relates to a convenient and labor-saving steel plate edge rolling forming tooling. Background Technology

[0002] With the development of society, all industries have entered a stage of precision development. Steel plates and composite materials are often used in industries such as construction and equipment. Steel plates are often used to cover the outside of other materials, which requires the steel plates to be rolled at the edges.

[0003] For example, patent application CN202520831706.6 discloses a convenient and labor-saving steel plate edge-rolling forming tool, including a support, a base plate fixedly installed at the bottom of the support, and multiple mounting slots symmetrically opened at the upper end of the support. An arc-shaped support plate is movably connected between two of the mounting slots. A first fixed shaft is fixedly installed inside the support, and both ends of the first fixed shaft extend to one side of the support and are movably installed with a first connecting rod. A second connecting rod is movably installed at the end of the first connecting rod away from the first fixed shaft, and a pressure roller is movably connected between the two second connecting rods. Multiple mounting slots are opened on the support, and arc-shaped support plates with different curvatures can be inserted and connected between two of the mounting slots to control the curvature of the steel plate bending. At the same time, the first fixed shaft, the first connecting rod, and the pressure roller are movably installed on the outside of the support, which can work with the arc-shaped support plate to bend the steel plate into structures with different curvatures. The overall structure is simple and easy to carry and operate manually.

[0004] Existing technologies, through the use of support plates, mounting grooves, and pressure rollers, can bend steel plates into structures with different curvatures, but there are still some shortcomings in their overall use: First, the existing technology can only bend strip-shaped steel plates and cannot be rolled. It can only bend strip-shaped steel plates and cannot roll round steel plates. It requires specific tooling for processing and has certain limitations in use. Secondly, although existing technologies can bend steel plates with different curvatures, after bending, the steel plates shift back to their original shape due to elastic recovery, resulting in bending angles or radii greater than expected. The aforementioned existing technologies do not have a springback correction mechanism, which leads to shape distortion and fails to meet design requirements, requiring re-rolling, which is time-consuming and labor-intensive. Finally, existing technology involves manually rolling the steel plate edges, which is difficult, labor-intensive, and inefficient. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention solves the following technical problems: the existing steel plate curling tooling is only suitable for bending strip steel plates and lacks the ability to adapt to curling round steel plates. It requires additional special tooling, has poor versatility, and although it can handle bending steel plates with different curvatures, the angle or radius is greater than expected due to the elastic recovery of the steel plate after bending. Since no springback correction mechanism is set, it is easy to cause shape distortion, fail to meet design requirements, and require repeated rework.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient and labor-saving steel plate edge-rolling forming fixture, comprising a processing table, a mold fixedly mounted on the upper surface of the processing table, a placement platform fixedly mounted on the top of the mold, a bending angle provided on the inner top of the placement platform, a turntable provided inside the mold, an electromagnet fixedly mounted on the top of the turntable, an adjusting column slidably mounted on one side of the mold, a roller rotatably mounted on the top of the adjusting column and above the placement platform, supports slidably mounted on both sides of the adjusting column, pressure rollers provided on the top of the supports, an electromagnetic heater fixedly mounted on the upper surface of the processing table on the side of the mold away from the adjusting column, and a fixing mechanism provided on the outer side of the mold for pre-fixing the steel plate.

[0007] Optionally, two first electric telescopic rods are fixedly installed on the lower surface of the processing table, and a support plate is fixedly installed on the output end of the two first electric telescopic rods. A first motor is fixedly installed on the upper surface of the support plate, and the output end of the first motor slides through the processing table and is fixed to the turntable.

[0008] Optionally, the upper surface of the processing table is provided with a groove on one side of the mold, an adjusting column is slidably installed inside the groove, two mounting plates are fixedly installed on the top of the adjusting column, and the roller is rotatably installed between the two mounting plates.

[0009] Optionally, a side plate is fixedly installed on the side of the processing table near the adjusting column. The side plate has a threaded rod inside, one end of which is rotatably connected to the adjusting column, and the other end is fixedly installed with a rotating wheel.

[0010] Optionally, a second electric telescopic rod is fixedly installed on the lower surface of the processing table. The output end of the second electric telescopic rod slides through the upper surface of the processing table and is fixed to the bottom end of the bracket.

[0011] Optionally, a rotating shaft is rotatably mounted between the top ends of the two brackets, and a mounting base is fixedly mounted on the surface of the rotating shaft. A second motor is embedded in the bottom of the mounting base, and the output end of the second motor is fixedly connected to the pressure roller.

[0012] Optionally, the fixing mechanism includes a support column fixedly installed on the upper surface of the processing table, and the surface of the support column is provided with a pressure plate.

[0013] Optionally, a fixing plate flush with the upper surface of the placement platform is fixedly installed on the surface of the support column, the pressure plate slides above the fixing plate and rotates in engagement, and a threaded sleeve is threadedly engaged at the top of the support column.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: This utility model, through the setting of mold, turntable, pressure roller and electromagnetic heater, can pre-bend the edge of steel plate, and then the pressure roller rotates to roll the edge. It can also adjust the rolling angle and curvature, preheat the steel plate and heat it during the rolling process. It can effectively reduce the springback and stress concentration of steel plate, improve product quality, and adjust the rolling angle and curvature to improve the use effect. This invention, through the use of a placement platform, bending angle, electromagnet, and rollers, can quickly pre-bend steel plates, facilitating subsequent edge-rolling. Simultaneously, the steel plate can rotate during edge-rolling, facilitating heating and further improving product quality. After edge-rolling, it can be quickly removed, making the operation simple, convenient, and improving work efficiency. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] refer to Figure 1 A convenient and labor-saving steel plate edge rolling forming tool includes a processing table 10, a support leg 11 fixedly installed on the lower surface of the processing table 10, a mold 12 fixedly installed on the upper surface of the processing table 10, and a placement platform 13 fixedly installed on the upper surface of the mold 12 for placing a circular steel plate. A bending angle 14 is provided on the inner top of the placement platform 13 for pre-bending the edge of the circular steel plate to facilitate subsequent edge rolling work.

[0019] Further reference Figure 1 and Figure 5 Four support columns 20 are fixedly installed on the upper surface of the processing table 10. A fixing plate 21 is fixedly installed in the middle of the support column 20. The upper surface of the fixing plate 21 is flush with the upper surface of the placement table 13. An eccentrically set pressure plate 22 is movably installed above the fixing plate 21 on the support column 20. A threaded sleeve 23 is threadedly fitted to the top of the support column 20. The eccentrically set pressure plate 22 is centered on the threaded sleeve 23. The pressure plate 22 on one side of the threaded sleeve 23 has a long end structure, and the pressure plate 22 on the other side of the threaded sleeve 23 has a short end structure. In use, the pressure plate 22 is initially positioned with its long end away from the placement platform 13. When the circular steel plate is placed on the upper surface of the placement platform 13, the pressure plate 22 will not cause interference. After placement, the long end of the pressure plate 22 is rotated to the upper surface of the steel plate, and then the threaded sleeve 23 is rotated. Since the threaded sleeve 23 is threadedly engaged with the support column 20, the threaded sleeve 23 moves downward, and the lower end face of the threaded sleeve 23 abuts against the upper surface of the pressure plate 22, thereby applying downward pressure to the pressure plate 22. The pressure plate 22 then applies pressure to the steel plate, thereby fixing the steel plate.

[0020] Further reference Figure 2 and Figure 3Two first electric telescopic rods 15 are fixedly installed on the lower surface of the processing table 10. Support plates 16 are fixedly installed on the piston ends of the two first electric telescopic rods 15. A first motor 17 is fixedly installed on the upper surface of the support plate 16. The output end of the first motor 17 slides through the processing table 10 and rotates in cooperation with it. A turntable 18, which slides inside the mold 12, is fixedly installed at its end. An electromagnet 19 is fixedly installed on the upper surface of the turntable 18. The electromagnet 19 is an electrical structure that generates strong magnetism when energized, which is existing technology and will not be elaborated upon in this application. In this application, the electromagnet 19 is selected to be annular and planar. After the steel plate is fixed, the output end of the first electric telescopic rod 15 retracts inward, thereby pulling the support plate 16 upward, which in turn drives the first motor 17, the turntable 18, and the electromagnet 19 upward, causing the electromagnet 19 to come into contact with the steel plate. Subsequently, the electromagnet 19 is energized to generate magnetism for attraction and fixation. By using the above-mentioned fixing method, uneven support at the bottom of the steel plate or deviation of the adsorption position from the center of the steel plate can be avoided, ensuring that the steel plate is in a balanced state and improving the fixing effect. After adsorption, the pressure plate 22 releases the restriction on the steel plate, and then the first electric telescopic rod 15 pushes the support plate 16 and other structures downward, thereby pulling the steel plate downward along the arc surface of the bending angle 14. As the center of the arc surface of the bending angle 14 gradually shrinks, the outer surface of the steel plate that is attached to the bending angle 14 will undergo a certain bending deformation upward, forming a pre-bending, which facilitates the subsequent edge rolling work. After pre-bending, the first electric telescopic rod 15 pulls the support plate 16 and other structures upward, so that the steel plate is located above the placement platform 13, preparing for the subsequent edge rolling work. It should be noted that this step is only a pre-bending, and does not require complete bending deformation. It is only necessary to destroy the original crystalline structure of the outer surface of the steel plate to facilitate the subsequent formal bending and edge rolling.

[0021] Further reference Figure 3 and Figure 4The upper surface of the processing table 10 is provided with a slide groove 24 on one side of the mold 12. An adjusting column 25 is slidably installed inside the slide groove 24. Two mounting plates 29 are fixedly installed on the top of the adjusting column 25. A roller 30 is rotatably installed between the two mounting plates 29. A side plate 26 is fixedly installed on the side of the processing table 10 near the adjusting column 25. A threaded rod 27 is threaded inside the side plate 26. One end of the threaded rod 27 is rotatably connected to the adjusting column 25, and a rotating wheel 28 is fixedly installed on the other end. After the steel plate is pre-bent and lifted above the placement platform 13, the rotating wheel 28 drives the threaded rod 27 connected to it to rotate. Since the threaded rod 27 is threadedly installed with the side plate 26, its other end can move forward when the threaded rod 27 rotates, thereby driving the adjusting column 25 to slide forward inside the slide groove 24, so that the roller 30 abuts against the curved part of the outer side of the steel plate to support the steel plate and facilitate the subsequent edge rolling work. In this scheme, the height of the roller 30 is adjusted according to the actual situation to fit the curved surface of the steel plate. It should be noted that when the steel plate is placed above the placement platform 13 and the roller 30 abuts against the curved part of the steel plate, the electromagnet 19 is always attracted and fixed to the bottom of the steel plate, so that the steel plate will not be displaced when it is bent and deformed, ensuring stability.

[0022] Further reference Figure 1 , Figure 3 and Figure 4A second electric telescopic rod 31 is fixedly installed on the lower surface of the processing table 10. The output end of the second electric telescopic rod 31 slides through the upper surface of the processing table 10 and is fixedly installed with two supports 32 symmetrically arranged around the adjusting column 25. A rotating shaft 33 is rotatably installed between the tops of the two supports 32. A servo motor 37 that drives the rotating shaft 33 is fixedly installed on one side of the support 32. A mounting base 34 is fixedly installed on the surface of the rotating shaft 33. A second motor 35 is embedded in the bottom of the mounting base 34. A pressure roller 36 is fixedly installed on the output end of the second motor 35. After the steel plate is lifted upward, its pre-bent outer circular surface is located between the roller 30 and the pressure roller 36. Then, through the above scheme, after the roller 30 abuts against the outside of the steel plate, the roller 30 continues to move forward, pushing the steel plate against the pressure roller 36. Simultaneously, the second electric telescopic rod 31 pulls the bracket 32 ​​downward. Since the bracket 32 ​​is curved, it drives the pressure roller 36 connected to it to move downward and away from the steel plate, forming an inward buckle to apply pressure to the pre-bent edge surface. At this time, the first motor 17 rotates, driving the adsorbed steel plate to rotate. At the same time, the second motor 35 also drives the pressure roller 36 to rotate. Since the pressure roller 36 applies pressure from top to bottom, it can continuously press the originally pre-bent edge surface downward to make it bend. Thus, the edge of the steel plate is curled and formed by the pressure roller 36. During this process, the roller 30 pushes the edge of the steel plate forward, which can adjust the angle between the bottom surface of the steel plate and the curled edge. When the servo motor 37 rotates, it drives the rotating shaft 33 to rotate, which in turn drives the pressure roller 36 to rotate, which can adjust the curvature of the curled edge and improve the use effect. Meanwhile, the steel plate and pressure roller 36 continue to rotate and roll the edge, which can correct the edge of the steel plate during the rolling process, effectively preventing the edge of the steel plate from springing back and improving product quality. After the edge rolling is completed, the steel plate is moved downward and removed from between the roller 30 and the pressure roller 36. The electromagnet 19 releases the steel plate from its fixation, allowing the formed steel plate to be removed quickly. The operation is convenient and labor-saving, speeding up work efficiency. Then the electromagnet 19 is reset to facilitate the next work.

[0023] Further reference Figure 3 An electromagnetic heater 38 is fixedly installed on the upper surface of the processing table 10 on the side of the mold 12 away from the adjusting column 25. The electromagnetic heater 38 is existing technology and is used to heat the edge of the steel plate. It will not be described in detail in this solution. When the steel plate rotates, it can preheat the edge before rolling. As the temperature rises, the yield strength of the steel plate will decrease significantly, and the steel plate will be more likely to undergo plastic deformation, which is convenient for rolling. During rolling, it can relieve stress concentration and make the stress distribution in the rolling process more uniform, thereby reducing the occurrence of rolling defects and improving the flatness and smoothness of the edge.

[0024] Finally, it should be noted that the present invention, a convenient and labor-saving steel plate edge rolling forming fixture, is intended to protect the various mechanical structures and related motion logic within this solution. Therefore, it does not elaborate on the various sensors, detectors, and driving components required for the actual operation of the specific mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can all be accomplished using conventional technical means. As long as the beneficial effects or the specific actions during the aforementioned work can be achieved, this solution can be implemented without imposing excessive restrictions.

[0025] Furthermore, the first electric telescopic rod 15, the first motor 17, the electromagnet 19, the second electric telescopic rod 31, the second motor 35, and the servo motor 37 of the convenient and labor-saving steel plate edge rolling forming tool in this utility model are all purchased from the market.
