DETAILED DESCRIPTION

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] according to Figures 1-6 As shown in the figure, this embodiment proposes a channel steel bending device for concealed rail turning mold, including a workbench 1, with load-bearing frames installed on both sides below the workbench 1 for connecting with external equipment.

[0024] The worktable 1 is equipped with a driving roller 2 and two sets of driven rollers 3 arranged symmetrically, such as Figure 1 As shown, the driving roller 2 and the two sets of driven rollers 3 form a triangle, and the channel steel is placed between the driving roller and the driven rollers. The position of the driven rollers 3 is then adjusted to bend the channel steel. This is based on the three-point bending mechanics principle. The driving roller 2 provides support force, and the two driven rollers 3 provide bending force. The channel steel 21 gradually undergoes plastic deformation within the force area, eventually completing the bending. By adjusting the spacing of the driven rollers, bending with different radii and angles can be achieved, making the processing flexible and highly adaptable. After bending, the driving roller 2 starts, and its rotation drives the channel steel 21 to move slowly forward. At this time, the positions of the driven rollers 3 and the driving roller 2 are fixed, serving as support points to ensure the stability of the channel steel 21 during the bending process. Then, as the channel steel 21 moves, the bending force is applied segment by segment to different positions, gradually completing a continuous curve or circular bend. Furthermore, the shaft of the driving roller 2 is connected to the worktable 1 through bearings and driven by a motor 4. The motor 4 is located below the worktable 1 and is fixedly connected to the worktable 1 through a bracket.

[0025] Driven roller 3 is driven by a hydraulic assembly. The worktable 1 has two symmetrically arranged assembly slots 15. The hydraulic assembly includes a partition 16 located within the assembly slots 15 and fixedly connected to the worktable 1. Multi-stage hydraulic push rods 17 are mounted on the partition 16. A load-bearing block 18 is mounted on the telescopic end of each multi-stage hydraulic push rod 17, and the load-bearing block 18 is connected to the driven roller 3 via bearings. The load-bearing block 18 can move within the assembly slots 15, while the driven roller 3 is perpendicular to the load-bearing block 18. Therefore, when the channel steel 21 is placed, the multi-stage hydraulic push rods 17 push the load-bearing block 18 to move, thereby driving the driven roller 3 to move.

[0026] Correspondingly, the spacer plate 16 is provided with a displacement sensor 19 and a limiting rod 20, one end of the displacement sensor 19 and the limiting rod 20 is connected with the workbench 1, the displacement sensor 19 and the limiting rod 20 pass through the bearing block 18, and the displacement sensor 19 is connected with the bearing block 18 through an induction block. The induction block corresponds to the displacement sensor 19, the displacement sensor 19 monitors the displacement of the bearing block 18 in real time through the induction block, and provides a high-precision feedback signal, so that when the bearing block 18 moves, the induction block moves on the sensing end of the displacement sensor 19, thereby the displacement sensor 19 judges the distance moved by the driven roller 3, and the feedback signal is transmitted to the total controller (the device has a total controller, which is a microcomputer).

[0027] The driving roller 2 and the driven roller 3 each include an upper roller 5 and a lower roller 6, the upper roller 5 and the lower roller 6 are connected through an adjusting assembly, and the upper roller 5 and the lower roller 6 are each provided with an outer edge 7, further, the diameters of the driving roller 2 and the driven roller 3 are each smaller than the outer edge 7, and the outer edge 7 is arranged in a ring shape. By using the arranged outer edge 7, the function of guiding and limiting the position of the channel steel 21 is formed, so as to ensure that the channel steel does not deviate from the position when bending, thereby improving the bending accuracy and stability.

[0028] The adjusting assembly includes a connecting column 8, the connecting column 8 is uniformly provided with a plurality of groups, and the connecting column 8 is connected with the upper roller 5, in the embodiment, the connecting column 8 is uniformly provided with six groups, as shown in Figure 4 The side of the connecting column 8 is provided with a connecting hole 9 on the lower roller 6, and the connecting hole 9 is provided with a plurality of groups from top to bottom, in the embodiment, each group of the connecting column 8 is correspondingly provided with four groups of the connecting hole 9, the connecting hole 9 is a threaded connecting hole, correspondingly, one group of the connecting hole 9 in the plurality of groups of the connecting hole 9 is connected with the connecting column 8 through a bolt, when the upper roller 5 and the lower roller 6 are in contact, at this time, the lowermost connecting hole 9 is connected with the connecting column 8 through the bolt, and when the position needs to be adjusted, the bolt needs to be disassembled first, then the upper roller 5 is pulled up by the staff, after reaching the predetermined position, the bolt is connected with the connecting hole 9 at the corresponding position, thereby, the position of the upper roller 5 of the device can change the spacing by adjusting the position of the connecting hole 9, and adapt to channel steels of different widths.

[0029] Meanwhile, the side of the connecting column 8 is provided with a limiting groove 10 on the lower roller 6, the inner side of the limiting groove 10 is provided with a limiting strip 11, and the limiting strip 11 is fixedly connected with the connecting column 8, the inner cavity of the limiting groove 10 is in communication with the connecting hole 9, the cooperation of the limiting groove 10 and the limiting strip 11 provides a limiting effect, so as to avoid displacement of the upper roller 5 or the connecting column 8 due to excessive pressure, thereby enhancing the adaptability of the equipment to channel steels of different widths.

[0030] The reinforcing assembly is provided with inner shafts 12, the outer sides of the inner shafts 12 are provided with support plates 13, the support plates 13 are provided with a plurality of groups, in the embodiment, the support plates 13 are also provided with six groups, the positions of the support plates 13 and the connecting columns 8 are staggered, the independence between the reinforcing assembly and the adjusting assembly is ensured, the two do not interfere with each other in function, the support plates 13 are provided with patches 14 at one end, and the patches 14 are connected with the upper roller 5 and the lower roller 6 at the corresponding positions. In the bending operation, the upper roller 5 and the lower roller 6 need to bear the great pressure of the channel steel. At this time, the reinforcing assembly provides additional support through the inner shafts 12, the support plates 13 and the patches 14, so as to prevent the roller from losing stability or deforming due to excessive pressure. At the same time, the uniformly distributed support plates 13 can effectively disperse external force and uniformly transmit the pressure to the overall structure of the roller, so as to ensure that the shape of the roller remains stable during the bending process. In the device, the structural strength of the upper roller 5 and the lower roller 6 is effectively improved through the reinforcing assembly, the equipment can not only adapt to the bending requirements of wider and thicker channel steels, but also can keep stable in long-time and high-intensity operation, thereby prolonging the service life.
