Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling bending machines, in particular to a rolling bending machine for an arc-shaped bottom plate of a bridge cantilever arm. Background Art
[0002] Roll bending machine is a professional metal profile cold bending equipment, especially suitable for bending aluminum alloy profiles. It can process various types of metal profiles, such as angle steel, channel steel, I-beam, metal square tube, metal round tube and various metal special-shaped profiles.
[0003] In the manufacturing process of the curved bottom plate of the bridge cantilever, a rolling machine is often used for precise bending processing. The rolling machine, with its efficient and accurate cold bending technology, can easily cope with the complex bending requirements of the curved bottom plate of the cantilever. Through the continuous rolling of the rolling machine, the bottom plate material can gradually be bent into the required arc shape, ensuring the accuracy and stability of the bridge cantilever. When the active roller of the rolling machine is adjusted in height through the hydraulic cylinder, due to pressure imbalance, uneven oil flow or wear and internal leakage of the hydraulic cylinder itself in the hydraulic system, the adjustment process of the two ends of the active roller may be inconsistent. When the adjustment process of the two ends of the active roller is inconsistent, it will directly affect the bending effect of the processed material, which may lead to problems such as inaccurate bending angle and uneven material deformation. At the same time, it will also make the active roller unable to perform normal height adjustment due to angle limitations. Utility Model Content

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-Figure 4 As shown, the bridge cantilever arc bottom plate rolling bending machine provided by the utility model comprises a base 1, on which two supports 2 are fixedly installed, a plurality of supporting wheels 3 are movably installed on the base 1 between the two supports 2, a driving mechanism 4, a control box 5, and a hydraulic box 6 are also fixedly installed on the base 1 located on one side of one of the supports 2, and the driving mechanism 4 and the hydraulic box 6 are electrically connected to the control box 5 through connecting lines, two driven rollers 7 are movably installed between the two supports 2, and hydraulic cylinders 8 are fixedly installed on the two supports 2, and the hydraulic cylinders 8 are connected to the hydraulic box 6 through pipelines. An output shaft 9 is movably installed in the driven roller 7, and an adjustment mechanism 10 is arranged at the lower end of the output shaft 9. The adjustment mechanism 10 includes a mounting seat 11, and bearing seats 12 are fixedly installed on the opposite sides of the two mounting seats 11, and compensation seats 13 are fixedly installed on both sides of the two mounting seats 11. The mounting seat 11 located in the compensation seat 13 is also fixedly installed with a compensation block 14, and a connecting shaft 15 is movably installed in the compensation block 14. Support shafts 16 are also movably installed in the compensation seats 13 located above and below the compensation block 14, and an active roller 25 is movably installed between the two mounting seats 11.
[0021] like Figure 2-Figure 3As shown, two limit blocks 17 are fixedly installed on the upper end of the mounting seat 11, and the ball seat at the lower end of the output shaft 9 is rotatably installed between the mounting seat 11 and the two limit blocks 17. With the help of the setting of the two limit blocks 17, the mounting seat 11 is movably installed on the lower end of the output shaft 9, which is convenient for adjusting an angle of the mounting seat 11. C-shaped mounting plates 18 are fixedly installed on the top and bottom of the compensation seat 13, and through-type slide grooves 19 are opened on both sides of the compensation seat 13. Through the setting of the C-shaped mounting plate 18, basic conditions can be provided for the movable installation of the support shaft 16 , a first fixing plate 20 is fixedly installed on the outer side of the support shaft 16, one end of the support shaft 16 passes through the through hole in the C-shaped mounting plate 18 and the compensation seat 13 and extends into the compensation seat 13, and the support shaft 16 located on the outer side of the C-shaped mounting plate 18 is threadedly connected with a nut, and the support shaft 16 located between the C-shaped mounting plate 18 and the first fixing plate 20 is also sleeved with a first compression spring 21. Through the arrangement of the two support shafts 16, the compensation block 14 can be placed in the center position of the compensation seat 13, and at the same time, an up and down compensation displacement of the mounting seat 11 can be achieved;
[0022] like Figure 2-Figure 4 As shown, the connecting shaft 15 passes through the through hole in the compensation block 14, and the two ends of the connecting shaft 15 respectively pass through the corresponding slide grooves 19 and extend to one side of the compensation seat 13. The connecting shaft 15 located on both sides of the compensation seat 13 is also movably installed with a second fixing plate 22 through nuts, and the connecting shaft 15 located between the second fixing plate 22 and the compensation seat 13 is also interspersed with a ball cover 23. The connecting shaft 15 located between the ball cover 23 and the second fixing plate 22 is sleeved with a second compression spring 24. By installing the compensation blocks 14 on both sides of the mounting seat 11, and cooperating with the connecting shaft 15, the second fixing plate 22, the ball cover 23, and the second compression spring 24, it can be achieved that when adjustment deviation occurs at both ends of the limit block 17, it is ensured that the two ends of the limit block 17 can continue to move and the height of the limit block 17 can be adjusted.
[0023] It should be noted that the utility model is a bridge cantilever arc bottom plate rolling bending machine. When the control box 5 controls the hydraulic box 6 to start the two hydraulic cylinders 8, the output shafts 9 in the two hydraulic cylinders 8 are synchronously lifted and lowered, so that the two output shafts 9 synchronously drive the corresponding mounting seats 11 to be lifted and lowered in the corresponding supports 2. Thus, the height adjustment of the active roller 25 can be achieved. When the two output shafts 9 have a lifting deviation, that is, a height difference between the two mounting seats 11, at this time, the mounting seat 11 first rotates a certain angle on the ball seat at the bottom of the output shaft 9 through the two limit blocks 17 at the top. At the same time, because the angle of the mounting seat 11 changes, the distance between the two mounting seats 11 will increase. Therefore, the compensation blocks 14 on both sides of the two mounting seats 11 rotate on the connecting shafts 15 in the corresponding compensation seats 13, so that the two mounting seats 11 drive the active roller 25 to change its angle, and then because the distance between the two mounting seats 11 increases, the mounting seats 11 cooperate with the active roller 25 to drive the compensation blocks 14 to move on the connecting shaft 15, so that the two mounting seats 11 are respectively moved obliquely on the corresponding connecting shafts 15 through the compensation blocks 14 on both sides, thereby ensuring that the two output shafts 9 respectively drive the corresponding mounting seats 11 to adjust to the specified height, thereby ensuring that the two mounting seats 11 can finally complete the height adjustment when there is a movement deviation.
