Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a steel bar bending machine for shield tunnel segment steel cages. Background Technology

[0002] my country is currently in a period of rapid industrialization and urbanization, with the construction industry developing rapidly. As a crucial component of tunnel engineering, the demand for tunnel boring machine (TBM) segments is constantly increasing. The processing of the steel reinforcement cage for TBM segments is one of the key steps in TBM segment production. As the main load-bearing component of the segments, the steel reinforcement requires a series of processing steps during segment production, including straightening, cutting, bending, and welding, to create a steel reinforcement cage that meets design requirements.

[0003] The existing rebar bending machine has a relatively complex structure and poor adaptability to rebars of different diameters, making it difficult to meet the diverse needs of segment production and reducing its applicability. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a highly applicable steel bar bending machine for shield tunnel segment steel cages.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A steel bar bending machine for shield tunnel segment steel cages, characterized in that it includes a worktable, a clamping component, a fixed ring, a rotating shaft, a rotating plate, and a screw. A limit block is fixedly connected to the front side of the upper surface of the worktable. The clamping component is connected to the leftmost side of the worktable and directly opposite the limit block. The fixed ring is fixedly connected to the worktable, with its leftmost end face flush with the leftmost end face of the limit block. The rotating shaft is rotatably connected to the worktable and located at the center of the fixed ring. The worktable has an internal cavity for mounting a motor. The output end of the motor is connected to the rotating shaft. The rotating plate is fixedly connected to the top of the rotating shaft. The bottom of the rotating plate has a recessed groove. The screw is rotatably connected to the groove. An adjusting motor is fixedly connected to one side of the inner wall of the groove. One end of the screw is rotatably connected to the other side of the inner wall of the groove, and the other end of the screw is connected to the output end of the adjusting motor. A slider is threaded onto the screw. The slider is slidably connected to the groove, and a pressure roller is fixedly connected to the bottom of the slider.

[0007] This invention creatively incorporates a worktable, clamping components, a fixed ring, a rotating shaft, a rotating plate, and a screw. The reinforcing bar is placed on the worktable, with its right side abutting against the leftmost end face of the limiting block. Simultaneously, the right side of the reinforcing bar abuts against the leftmost end face of the fixed ring. The clamping components are used to clamp and position the reinforcing bar. Then, the adjusting motor is started to drive the screw to rotate, matching the slider and the slide groove. The screw rotation causes the slider to slide within the slide groove, thereby causing the pressure roller at the bottom of the slider to slide until the pressure roller abuts against the left side of the reinforcing bar. At this point, the motor is started to drive the rotating shaft to rotate clockwise, causing the pressure roller under the rotating plate to swing. Because the pressure roller is in close contact with the left side of the reinforcing bar, its clockwise swing allows the right side of the reinforcing bar to be pressed tightly against the fixed ring for bending operations.

[0008] This device has a relatively simple structure and can adapt to steel bars of different diameters, meeting the diverse needs of segment production and improving its applicability.

[0009] In the above-mentioned steel bar bending machine for shield tunnel segment steel cage, bases are fixedly connected to both sides of the bottom of the workbench.

[0010] The base makes the overall structure of the device more stable.

[0011] In the above-mentioned steel bar bending machine for shield tunnel segment steel cage, the clamping component includes a fixed block, a clamping block and an adjusting screw. The fixed block is fixedly connected to one side of the upper part of the worktable, and the clamping block is slidably connected to the upper part of the worktable and located between the fixed block and the limiting block. The fixed block, the clamping block and the limiting block are all directly opposite each other. The adjusting screw is threadedly connected to the fixed block and the right end face of the adjusting screw is rotatably connected to the clamping block.

[0012] The fixing block, clamping block, and limiting block are located on the same horizontal line. Rotating the adjusting screw can move the clamping block closer to or away from the limiting block, thereby enabling the clamping block to clamp and position steel bars of different diameters.

[0013] In the above-mentioned steel bar bending machine for shield tunnel segment steel cage, the left end face of the adjusting screw is fixedly connected to an operating handle, and the operating handle is evenly distributed with several anti-slip protrusions.

[0014] The handle design makes it easier for staff to rotate and adjust the screw, and the anti-slip bumps increase the friction between the staff's palm and the handle.

[0015] In the above-mentioned steel bar bending machine for shield tunnel segment steel cage, the opposing surfaces of the limiting block and the clamping block are respectively fixed with anti-slip silicone pads.

[0016] The anti-slip silicone pad increases the friction between the limiting block, clamping block and the reinforcing bar, allowing the reinforcing bar to be clamped and positioned more stably.

[0017] Compared with existing technologies, this shield tunnel segment rebar bending machine innovatively incorporates a worktable, clamping components, a fixed ring, a rotating shaft, a rotating plate, and a screw. The rebar is placed on the worktable with its right side against the leftmost end face of the limiting block. Simultaneously, the right side of the rebar is against the leftmost end face of the fixed ring. The clamping components clamp and position the rebar. Then, the adjusting motor drives the screw to rotate, matching the slider and the slide groove. The screw rotation causes the slider to slide within the slide groove, thereby causing the pressure roller at the bottom of the slider to slide until it abuts against the left side of the rebar. At this point, the motor drives the rotating shaft to rotate clockwise, causing the pressure roller under the rotating plate to swing. Because the pressure roller is in close contact with the left side of the rebar, its clockwise swing ensures the right side of the rebar is pressed against the fixed ring for bending.

[0018] This device has a relatively simple structure and can adapt to steel bars of different diameters, meeting the diverse needs of segment production and improving its applicability. Attached Figure Description

[0025] like Figure 1 and Figure 2 As shown, this steel bar bending machine for shield tunnel segment reinforcement cages includes a workbench 1, a clamping component 2, a fixed ring 3, a rotating shaft 4, a rotating plate 5, and a screw 52. A limit block 11 is fixedly connected to the front side of the upper surface of the workbench 1. The clamping component 2 is connected to the leftmost side of the workbench 1 and directly opposite the limit block 11. The fixed ring 3 is fixedly connected to the workbench 1, and its leftmost end face is flush with the leftmost end face of the limit block 11. The rotating shaft 4 is rotatably connected to the workbench 1, and the rotating shaft 4 is located at the center of the fixed ring 3. The workbench 1 has an internal structure for mounting a motor. The inner cavity of motor 12 is connected to the output end of motor 12 and rotating shaft 4. Rotating plate 5 is fixed to the top of rotating shaft 4. The bottom of rotating plate 5 has a recessed groove 51. Screw 52 is rotatably connected to the groove 51. Adjusting motor 53 is fixedly connected to one side of the inner wall of groove 51. One end of screw 52 is rotatably connected to the other side of the inner wall of groove 51. The other end of screw 52 is connected to the output end of adjusting motor 53. Slider 54 is threadedly connected to screw 52. Slider 54 is slidably connected to groove 51 and pressure roller 6 is fixedly connected to the bottom of slider 54.

[0026] The workbench 1 has bases 13 fixedly connected to both sides of its bottom.

[0027] The clamping component 2 includes a fixing block 21, a clamping block 22, and an adjusting screw 23. The fixing block 21 is fixedly connected to one side of the upper part of the worktable 1. The clamping block 22 is slidably connected to the upper part of the worktable 1 and is located between the fixing block 21 and the limiting block 11. The fixing block 21, the clamping block 22, and the limiting block 11 are all directly opposite each other. The adjusting screw 23 is threadedly connected to the fixing block 21, and the right end face of the adjusting screw 23 is rotatably connected to the clamping block 22.

[0028] The left end face of the adjusting screw 23 is fixedly connected to the operating handle 24, and the operating handle 24 is evenly distributed with a number of anti-slip protrusions 25.

[0029] The opposing surfaces of the limiting block 11 and the clamping block 22 are respectively fixed with anti-slip silicone pads 26.

[0030] This utility model creatively sets up a workbench, clamping components, a fixing ring, a rotating shaft, a rotating plate, and a screw. The reinforcing bar is placed on the workbench, with its right side abutting against the leftmost end face of the limiting block. At the same time, the right side of the reinforcing bar abuts against the leftmost end face of the fixing ring. The clamping components are used to clamp and position the reinforcing bar. Rotating the adjusting screw can move the clamping block closer to or away from the limiting block, thus the clamping block can clamp and position reinforcing bars of different diameters.

[0031] Then, the adjusting motor is started to drive the screw to rotate. The slider and the slide groove are matched. The rotation of the screw can drive the slider to slide in the slide groove, thereby driving the pressure roller at the bottom of the slider to slide until the pressure roller abuts against the left side of the steel bar.

[0032] At this time, the motor drives the rotating shaft to rotate clockwise, causing the pressure roller under the rotating plate to swing. Since the pressure roller is close to the left side of the steel bar, when the pressure roller swings clockwise, it can make the right side of the steel bar close to the fixed ring for bending.

[0033] This device has a relatively simple structure and can adapt to steel bars of different diameters, meeting the diverse needs of segment production and improving its applicability.

[0034] It is worth noting that the diameter range of the reinforcing bars applicable to this solution is always smaller than the height of the pressure roller, and the factory can produce this device with different pressure roller heights according to different needs.

[0035] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
