Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to an improved rolling device for bending machines. Background Technology

[0002] A bending machine is a mechanical device used to process metal materials. It is mainly used to bend metal sheets into specific angles or shapes under pressure to produce various mechanical parts and components. Therefore, bending machines are widely used in the manufacturing industry, covering almost every sector.

[0003] An existing patent (application number 201821782779.7) discloses a rolling device for a bending machine, including a mounting base. Two support plates are symmetrically welded to the upper end of the mounting base. Two rotating rollers are provided at the lower end between the two support plates. Rotating shafts are fixedly connected to both sides of the two rotating rollers. The other ends of the two rotating shafts are inserted into the corresponding support plates. The other sides of the two rotating shafts located on the same side pass through the support plates and are fixedly connected to a driving mechanism. A moving roller is provided at the upper end between the two support plates. Connecting shafts are fixedly connected to both sides of the moving rollers. The other sides of the two connecting shafts are connected to the moving mechanism. Two limiting plates are symmetrically provided between the two support plates. Through holes matching the moving rollers and rotating rollers are opened on the two limiting plates. A displacement mechanism is fixedly connected to the lower end of the two limiting plates.

[0004] In the aforementioned patent, the two rotating rollers are difficult to move and adjust as needed. However, for different types of sheet materials, the required bending position or bending angle is different, which leads to certain limitations in the use of the device. Summary of the Invention

[0005] The main objective of this invention is to provide an improved rolling device for bending machines, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An improved rolling device for a bending machine includes a base, a mounting bracket fixedly mounted on the upper left side of the base, a controller fixedly mounted on the front middle of the mounting bracket, a hydraulic cylinder fixedly mounted through the upper right side of the mounting bracket, an adjustment device mounted on the lower right side of the mounting bracket, a mounting seat fixedly mounted through the upper middle of the base, a support device mounted on the upper end of the mounting seat, a fixing frame fixedly mounted on the lower right side of the mounting seat, and a servo motor fixedly mounted on the upper end of the fixing frame.

[0008] Preferably, the support device includes a support plate with a support groove at its right end. A slider is fixedly installed at the lower center of the support plate, and a sliding groove is opened at the upper end of the mounting base. A threaded rod is fixedly installed at the output end of a servo motor. The slider is threaded onto the threaded rod, and the threaded rod is rotatably installed in the sliding groove. The support plate is slidably installed on the mounting base via the slider. The servo motor drives the threaded rod to rotate in the sliding groove. At this time, the slider on the threaded rod drives the support plate to slide on the sliding groove. The support plate then passes through the support groove and is inserted into the right end of the two support rollers and the pressure roller. This not only limits the movement of the sheet material to prevent it from swaying during bending, but also supports the support rollers, improving their load-bearing capacity.

[0009] Preferably, the adjustment device includes a second servo motor, with a forward and reverse screw fixedly mounted at the output end of the second servo motor. Second sliders are mounted on both the forward and reverse threads of the forward and reverse screws. Support rollers are fixedly mounted on the right ends of both second sliders. A second groove is formed at the lower right end of the mounting frame, and the forward and reverse screws are rotatably mounted within the second groove. The second servo motor is fixedly mounted at the lower rear end of the mounting frame. The second servo motor drives the forward and reverse screws to rotate within the second groove. At this time, the two second sliders on the forward and reverse screws move closer or further apart within the second groove, thereby allowing the distance between the two support rollers to be adjusted according to the required bending angle of different sheet materials.

[0010] Preferably, a pressure roller is fixedly installed at the output end of the hydraulic cylinder, and the pressure roller and two support rollers are arranged in a triangular pattern. By driving the pressure roller downward with the hydraulic cylinder, the sheet material on the two support rollers can be pressed down and bent into shape.

[0011] Preferably, the support groove is cross-shaped, and the support groove corresponds left and right to the pressure roller and the two support rollers.

[0012] Preferably, the controller is electrically connected to the hydraulic cylinder, the first servo motor, and the second servo motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The second servo motor on the adjusting device drives the positive and negative screws to rotate in the second slide groove. At this time, the two second sliders on the positive and negative screws move closer or further apart in the second slide groove, so that the distance between the two support rollers can be adjusted according to the bending angle of different plates, thereby improving the applicability of the device.

[0015] After the two support rollers are adjusted, the sheet material is placed on the two support rollers, with one end of the sheet material tightly against the mounting frame. Then, the first servo motor drives the threaded rod to rotate in the first slide groove. At this time, the first slider on the threaded rod drives the support plate on it to slide on the first slide groove. The support plate then passes through the support groove on it and is inserted into the two support rollers and the right end of the pressure roller. This not only limits the sheet material and prevents it from swaying from side to side during bending, but also supports the support rollers, improving their load-bearing capacity. Finally, the hydraulic cylinder drives the pressure roller to press down, bending the sheet material on the two support rollers into shape. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1-4 As shown, an improved rolling device for a bending machine includes a base 1. A mounting bracket 5 is fixedly installed on the upper left side of the base 1. A controller 6 is fixedly installed on the front middle of the mounting bracket 5. A hydraulic cylinder 4 is inserted and fixedly installed on the upper right side of the mounting bracket 5. An adjusting device 3 is installed on the lower right side of the mounting bracket 5. A mounting seat 7 is inserted and fixedly installed on the upper middle of the base 1. A support device 2 is installed on the upper end of the mounting seat 7. A fixing frame 8 is fixedly installed on the lower right side of the mounting seat 7. A servo motor 9 is fixedly installed on the upper end of the fixing frame 8.

[0025] The support device 2 includes a support plate 20 with a support groove 21 at its right end. A slider 23 is fixedly installed at the lower middle of the support plate 20. A sliding groove 24 is opened at the upper end of the mounting base 7. A threaded rod 22 is fixedly installed at the output end of a servo motor 9. The slider 23 is threaded onto the threaded rod 22, and the threaded rod 22 is rotatably installed in the sliding groove 24. The support plate 20 is slidably installed on the mounting base 7 via the slider 23. The servo motor 9 drives the threaded rod 22 to rotate in the sliding groove 24. At this time, the slider 23 on the threaded rod 22 drives the support plate 20 to slide on the sliding groove 24. The support plate 20 then passes through the support groove 21 and is inserted into the right end of the two support rollers 33 and the pressure roller 40. This not only limits the movement of the sheet material to prevent it from swaying left and right during bending, but also allows the support rollers 33 to be supported by the support plate 20, improving their load-bearing capacity.

[0026] The adjustment device 3 includes a second servo motor 30. A forward and reverse screw 31 is fixedly mounted on the output end of the second servo motor 30. Second sliders 32 are mounted on both the forward and reverse threads of the forward and reverse screws 31. Support rollers 33 are fixedly mounted on the right ends of both second sliders 32. A second groove 34 is opened at the lower right end of the mounting frame 5. The forward and reverse screws 31 are rotatably mounted within the second groove 34. The second servo motor 30 is fixedly mounted at the lower rear end of the mounting frame 5. The controller 6 is electrically connected to the hydraulic cylinder 4, the first servo motor 9, and the second servo motor 30. The second servo motor 30 drives the forward and reverse screws 31 to rotate within the second groove 34. At this time, the two second sliders 32 on the forward and reverse screws 31 move closer or further apart within the second groove 34, thereby allowing the distance between the two support rollers 33 to be adjusted according to the required bending angle of different sheet materials.

[0027] A pressure roller 40 is fixedly installed at the output end of the hydraulic cylinder 4. The pressure roller 40 and two support rollers 33 are arranged in a triangular pattern. The support groove 21 is cross-shaped, and the support groove 21 corresponds left and right to the pressure roller 40 and the two support rollers 33. The hydraulic cylinder 4 drives the pressure roller 40 to press down, thereby pressing down and bending the sheet metal on the two support rollers 33 into shape. The electrical equipment of this utility model is all existing technology, and the electrical equipment can operate normally during trial operation.

[0028] It should be noted that this utility model is an improved rolling device for a bending machine. First, the controller 6 is connected to an external power source. Then, the second servo motor 30 on the adjusting device 3 drives the positive and negative screws 31 to rotate within the second slide groove 34. At this time, the two second sliders 32 on the positive and negative screws 31 move closer or further apart within the second slide groove 34, thereby allowing the two support rollers 33 to adjust their distance according to the bending angle required for different plates, thus improving the applicability of the device. Next, the plate is placed on the two support rollers 33, with one end of the plate tightly against the mounting frame 5. The threaded rod 22 is driven to rotate in the first slide groove 24 by the first servo motor 9. At this time, the first slider 23 on the threaded rod 22 drives the support plate 20 on it to slide on the first slide groove 24. The support plate 20 then passes through the support groove 21 on it and is inserted into the two support rollers 33 and the right end of the pressure roller 40. This not only limits the material and prevents the material from swaying left and right when bending, but also allows the support rollers 33 to be supported by the support plate 20, which improves the bearing capacity of the support rollers 33. Finally, the pressure roller 40 is driven to press down by the hydraulic cylinder 4 to press down and bend the material on the two support rollers 33 into shape.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
