Description

Technical Field

[0001] The invention relates to the technical field of building engineering construction, in particular to a double-station steel bar bending machine for building engineering construction. Background Art

[0002] In the field of construction, steel bars are key materials for building concrete structures, and their processing efficiency and quality directly affect the progress and safety of the project. In the construction industry, the building base adopts reinforced concrete structure, in which the main body of reinforced concrete is made of steel cages. When making steel cages, the steel bars need to be cut and bent. Traditional single-station steel bending machines have slow processing speeds when facing large-scale engineering construction and cannot meet the needs of fast construction.

[0003] At present, the existing steel bar bending machines can only bend one steel bar at a time. When processing multiple specifications of steel bars at the same time, frequent mold changes and parameter adjustments are not only time-consuming and labor-intensive, but also prone to processing errors. With the development of the construction industry, the demand for efficient and accurate steel bar processing equipment is becoming increasingly urgent. Moreover, when bending multiple steel bars, the multiple steel bars are prone to get stuck with each other after bending, and need to be separated by manpower, which increases labor intensity and reduces bending efficiency. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A double-station steel bar bending machine for construction engineering, comprising: a frame, an operating table is fixedly installed on the top of the frame, and a stabilizing frame is fixedly installed inside the frame;

[0005] Bending components, the bending components are provided in two groups, the bottoms of the two groups of bending components are both installed with positioning plates, and the positioning plates are respectively fixedly installed on both sides of the top of the operating table;

[0006] A positioning assembly, which is used for clamping and guiding the steel bars. The positioning assembly is fixedly installed on the top of the bending assembly. A guide guard is installed on the side of the positioning assembly close to the positioning plate. The guide guard is fixedly installed on the top of the positioning plate, and the guide guard and the positioning assembly are arranged on the same central axis. When bending the steel bars, the steel bars are inserted into the guide guard. At this time, the staff rotates the positioning assembly to clamp the steel bars in the positioning assembly, and then the staff twists the bending assembly to cause the steel bars to be twisted and bent. The steel bar bending equipment is a double-station setting, which can perform bending operations on two groups of steel bars at the same time. Compared with single-station bending equipment, the processing efficiency is greatly improved, and the bending task of a large number of steel bars can be completed in a shorter time.

[0007] Among them, the guiding and protecting member includes a beam frame. On both sides of the bottom of the beam frame, cushion blocks are fixedly installed. On both sides of the top of the cushion blocks, clamping blocks are fixedly installed. Both of the clamping blocks are fixedly installed on the outer side of the beam frame. On the bottom of the cushion blocks, a support plate is fixedly installed. Between the opposite surfaces of the cushion blocks and the support plate, an extrusion pad is fixedly installed. When guiding the steel bars, the staff inserts the steel bars into the bent pipe. At this time, the steel bars pass through the guiding frame group. At this time, the steel bars are placed above the beam frame. When the steel bars are placed on the beam frame, the cushion blocks below are extruded. At this time, the extrusion pads below the cushion blocks and the support plate are deformed due to the extrusion of the weight of the steel bars. When the steel bars shake during pushing, the beam frame stably supports the steel bars to prevent the shaking of the steel bars from affecting the guiding accuracy during feeding.

[0008] Preferably, the support plate is fixedly installed on the top of the positioning disk. There are two groups of extrusion pads, and the two groups of extrusion pads are symmetrically arranged with the beam frame as the center. At the middle of the bottom of the beam frame, an adapter plate is fixedly installed.

[0009] Preferably, on both sides of the top of the adapter plate, bent pipes are fixedly installed. There are two bent pipes, and both of the bent pipes are installed on the outer surface of the beam frame. On the surface of the bent pipe close to the bending assembly, a guiding frame group is fixedly installed.

[0010] Preferably, the guiding frame group includes a positioning through plate. On the outer surface of the positioning through plate, a connecting rod is fixedly installed. On the outer surface of the connecting rod, an extension sleeve column is fixedly installed. On both sides of the outer surface of the connecting rod away from the positioning through plate, clamping plates are fixedly installed. The steel bars are placed on the beam frame and pass through the bent pipe and the positioning through plate and extend into the positioning assembly to guide the steel bars.

[0011] Preferably, on the outer side of the clamping plate, a side connection block is clamped. On the outer surface of the side connection block, an extension block is fixedly installed. The extension block is placed on both sides of the top of the beam frame.

[0012] Preferably, the extrusion pad includes a hollow pad. The hollow pad is fixedly installed between the opposite surfaces of the cushion block and the support plate. There are two hollow pads. Between the opposite surfaces of the two hollow pads, a rotating rod is rotatably installed. On the outer surface of the rotating rod, a sleeve ring is sleeved. On the surface of the sleeve ring, a bent arc piece is fixedly installed. When the steel bars are placed above the beam frame and pushed into the positioning assembly, since the steel bars are long and prone to shaking during guiding, at this time, the shaking steel bars extrude the cushion blocks, so that the hollow pads installed between the cushion blocks and the support plate are deformed due to extrusion. At this time, the bent arc piece is extruded to drive the bent arc piece to rotate on the surface of the rotating rod to buffer the shaking steel bars.

[0013] Preferably, the positioning assembly includes a positioning shaft. On the top of the positioning shaft, a round shaft is fixedly installed. There are two round shafts, and on the surfaces of both round shafts, clamping blocks are rotatably installed.

[0014] Preferably, a slider is fixedly installed at the bottom of the clamping block, and the outer surface of the slider is slidably adapted to be provided with a guide groove, and the guide groove is fixedly installed on the top of the positioning plate. The staff rotates the clamping block to make the slider slide and move in the guide groove, and the clamping block rotates on the surface of the circular shaft to adjust the spacing between the clamping blocks on both sides to clamp and fix the steel bar, and the staff adjusts the swivel seat to the side of the circular shaft to make the torsion plate staggered with the swivel seat, so that the swivel seat is adjusted to one side of the steel bar, and the bending assembly is driven by power to push or bend the steel bar according to the preset angle and radius, so that the steel bar undergoes plastic deformation to achieve the required bending shape and angle.

[0015] Preferably, the bending assembly includes a chassis, a torsion disk is rotatably mounted on the top of the chassis, the torsion disk is sleeved on the outer surface of the positioning shaft, a swivel seat is fixedly mounted on the top of the torsion disk, a sleeve block is fixedly mounted on the top axis of the swivel seat, and a handle is fixedly mounted on the outer surface of the sleeve block.

[0016] The outer surface of the rotating seat is fixedly installed with a fitting piece, and the outer surfaces of the fitting piece are fixedly installed with limiting pieces on both sides, and the limiting pieces are clamped on both sides of the outer surface of the steel bar. The steel bar is clamped in the clamping blocks on both sides, and the staff turns the handle to make the torsion disk rotate outside the positioning shaft, and the rotating seat rotates until it contacts the steel bar. Then the staff turns the handle and makes the limiting pieces clamp on the surface of the steel bar to bend the steel bar, so as to avoid the deviation of the steel bar when it is twisted and affect the bending curvature of the steel bar. The steel bar is accurately fixed at the position to be bent through the guide frame group and the extrusion pad, ensuring that the steel bar will not shift or shake during the bending process, and the bending accuracy is guaranteed.

[0017] The present invention provides a double-station steel bar bending machine for construction engineering. It has the following beneficial effects:

[0018] 1. The double-station rebar bending machine used in the construction project inserts the rebar into the guide guard when bending the rebar. At this time, the staff rotates the positioning assembly to clamp the rebar in the positioning assembly, and then the staff twists the bending assembly to cause the rebar to be twisted and bent. The rebar bending equipment is a double-station setting, which can perform bending operations on two groups of rebars at the same time. Compared with single-station bending equipment, the processing efficiency is greatly improved, and the bending task of a large number of rebars can be completed in a shorter time.

[0019] 2. The double-station rebar bending machine used in the construction of this construction project, when the rebar is guiding the material, the worker inserts the rebar into the bending pipe, and the rebar passes through the guide frame group. At this time, the rebar is erected above the beam frame. When the rebar is placed above the beam frame, the pad below is squeezed. At this time, the pad and the extrusion pad under the support plate are deformed by the weight of the rebar. When the rebar is pushed and shakes, the beam frame stably supports the rebar to avoid the shaking of the rebar during feeding and affecting the accuracy of material guiding.

[0020] 3. When the double-station rebar bending machine used in the construction of the building project places the rebar on top of the beam and pushes it into the positioning assembly, the rebar is prone to shaking during guidance due to its long length. At this time, the shaking rebar squeezes the pad, causing the hollow pad installed between the pad and the support plate to be squeezed and deformed. At this time, the arc-bending piece is squeezed and drives the arc-bending piece to rotate on the surface of the rotating rod to cushion the shaking rebar.

[0021] 4. The double-station rebar bending machine used in the construction project rotates the clamping block to make the slider slide in the guide groove. At this time, the clamping block rotates on the surface of the circular shaft to adjust the distance between the clamping blocks on both sides to clamp and fix the rebar. At this time, the staff adjusts the swivel seat to the side of the circular shaft to make the torsion disk staggered with the swivel seat so that the swivel seat is adjusted to one side of the rebar. Under power drive, the bending assembly pushes or bends the rebar according to the preset angle and radius, causing the rebar to undergo plastic deformation to achieve the required bending shape and angle.

[0022] 5. The double-station rebar bending machine used in the construction of this construction project clamps the rebar in the clamps on both sides. The worker turns the handle to make the torsion disk rotate on the outside of the positioning shaft, and the swivel seat rotates until it contacts the rebar. Then the worker twists the handle and makes the limit plate clamp on the surface of the rebar to bend the rebar to avoid displacement when the rebar is twisted, affecting the bending curvature of the rebar. The guide frame group and the extrusion pad are used to accurately fix the rebar in the position to be bent, ensuring that the rebar will not shift or shake during the bending process, thereby ensuring the bending accuracy.

[0037] Bending components 7, wherein two groups of the bending components 7 are provided, and positioning plates 4 are installed at the bottom of the two groups of the bending components 7, and the positioning plates 4 are respectively fixedly installed on both sides of the top of the operating table 1;

[0038] The positioning component 6 is used for clamping and guiding the steel bars. The positioning component 6 is fixedly installed on the top of the bending component 7. A guide guard 5 is installed on the side of the positioning component 6 close to the positioning plate 4. The guide guard 5 is fixedly installed on the top of the positioning plate 4, and the guide guard 5 and the positioning component 6 are arranged on the same central axis; when bending the steel bars, the steel bars are inserted into the guide guard 5. At this time, the staff rotates the positioning component 6 to clamp the steel bars in the positioning component 6, and then the staff twists the bending component 7 so that the steel bars are twisted and bent. The steel bar bending equipment is a double-station setting, which can perform bending operations on two groups of steel bars at the same time. Compared with single-station bending equipment, the processing efficiency is greatly improved, and the bending task of a large number of steel bars can be completed in a shorter time.

[0039] The guide guard 5 includes a beam frame 51, and pads 56 are fixedly installed on both sides of the bottom of the beam frame 51, and blocks 57 are fixedly installed on both sides of the top of the pads 56. The two blocks 57 are fixedly installed on the outside of the beam frame 51. A support plate 54 is fixedly installed on the bottom of the pads 56, and an extrusion pad 55 is fixedly installed between the opposite surfaces of the pads 56 and the support plate 54. When the steel bars are guiding the material, the staff inserts the steel bars into the curved pipe 53, and the steel bars pass through the guide frame group 52. At this time, the steel bars are erected above the beam frame 51. When the steel bars are placed above the beam frame 51, the pads 56 below are squeezed. At this time, the pads 56 and the extrusion pads 55 below the support plates 54 are squeezed and deformed by the weight of the steel bars. When the steel bars are pushed and shaken, the beam frame 51 stably supports the steel bars to prevent the steel bars from shaking during feeding and affecting the guiding accuracy.

[0040] The support plate 54 is fixedly installed on the top of the positioning plate 4 . Two groups of compression pads 55 are provided. The two groups of compression pads 55 are symmetrically arranged with the beam frame 51 as the center. A connecting plate 58 is fixedly installed in the middle of the bottom of the beam frame 51 .

[0041] Bend pipes 53 are fixedly installed on both sides of the top of the connecting plate 58. There are two bend pipes 53. Both bend pipes 53 are installed on the outer surface of the beam frame 51. A guide frame group 52 is fixedly installed on the surface of the bend pipe 53 close to the bending component 7.

[0042] The second embodiment is based on the first embodiment. Figure 8 , Fig. 9 and Fig.11 As shown, the guide frame assembly 52 includes a positioning through plate 523, a connecting rod 522 is fixedly installed on the outer surface of the positioning through plate 523, an extension sleeve 521 is fixedly installed on the outer surface of the connecting rod 522, and a clamping plate 524 is fixedly installed on both sides of the outer surface of the connecting rod 522 away from the positioning through plate 523. The steel bar is installed on the beam frame 51, passes through the elbow 53 and the positioning through plate 523 and extends into the positioning assembly 6 to guide the steel bar.

[0043] The outer side of the clamping plate 524 is clamped with a side block 525 , and the outer surface of the side block 525 is fixedly mounted with an extension block 526 . The extension block 526 is mounted on both sides of the top of the beam frame 51 .

[0044] The compression pad 55 includes a hollow pad 553, which is fixedly installed between the opposite surfaces of the pad 56 and the support plate 54. Two hollow pads 553 are provided, and a rotating rod 552 is rotatably installed between the opposite surfaces of the two hollow pads 553. The outer surface of the rotating rod 552 is sleeved with a collar 551, and a curved piece 554 is fixedly installed on the surface of the collar 551. When the steel bar is placed on the top of the beam frame 51 and pushed into the positioning assembly 6, the steel bar is easy to shake during the guidance due to its long length. At this time, the shaking steel bar squeezes the pad 56, so that the hollow pad 553 installed between the pad 56 and the support plate 54 is squeezed and deformed. At this time, the curved piece 554 is squeezed and drives the curved piece 554 to rotate on the surface of the rotating rod 552 to buffer the shaking steel bar.

[0045] The third embodiment is based on the first and second embodiments. Figures 4 to 7 As shown, the positioning assembly 6 includes a positioning shaft 63 , a round shaft 64 is fixedly mounted on the top of the positioning shaft 63 , two round shafts 64 are provided, and clamping blocks 61 are rotatably mounted on the surfaces of the two round shafts 64 .

[0046] The bottom of the clamp block 61 is fixedly installed with a slider 65, and the outer surface of the slider 65 is slidably adapted with a guide groove 62, and the guide groove 62 is fixedly installed on the top of the positioning plate 4. The staff rotates the clamp block 61 to make the slider 65 slide and move in the guide groove 62. At this time, the clamp block 61 rotates on the surface of the circular shaft 64 to adjust the spacing between the clamp blocks 61 on both sides to clamp and fix the steel bar, and at this time, the staff adjusts the rotating seat 73 to the side of the circular shaft 64, so that the torsion plate 72 is staggered with the rotating seat 73, so that the rotating seat 73 is adjusted to one side of the steel bar.

[0047] The bending assembly 7 includes a chassis 74, a torsion plate 72 is rotatably mounted on the top of the chassis 74, the torsion plate 72 is sleeved on the outer surface of the positioning shaft 63, a swivel seat 73 is fixedly mounted on the top of the torsion plate 72, a sleeve block 76 is fixedly mounted on the top axis of the swivel seat 73, and a turning handle 71 is fixedly mounted on the outer surface of the sleeve block 76.

[0048] The outer surface of the rotating seat 73 is fixedly mounted with a fitting sheet 77, and the outer surfaces of the fitting sheet 77 are fixedly mounted with limiting sheets 75 on both sides, and the limiting sheets 75 are clamped on both sides of the outer surface of the steel bar. The steel bar is clamped in the clamping blocks 61 on both sides, and the staff rotates the turning handle 71 to make the torsion plate 72 rotate outside the positioning shaft 63, and the rotating seat 73 rotates to contact the steel bar, and then the staff rotates the turning handle 71 and makes the limiting sheets 75 clamped on the surface of the steel bar to bend the steel bar, so as to avoid the deviation of the steel bar when it is twisted and affect the bending curvature of the steel bar, and the steel bar is accurately fixed at the position to be bent through the guide frame group 52 and the extrusion pad 55, so as to ensure that the steel bar will not shift or shake during the bending process, and the bending accuracy is guaranteed.

[0049] During use, when bending the steel bars, the steel bars are inserted into the guide guard 5. At this time, the staff rotates the positioning assembly 6 to clamp the steel bars in the positioning assembly 6, and then the staff twists the bending assembly 7 to cause the steel bars to be twisted and bent. The steel bar bending equipment is a double-station setting, which can perform bending operations on two groups of steel bars at the same time. Compared with single-station bending equipment, the processing efficiency is greatly improved, and the bending task of a large number of steel bars can be completed in a shorter time.

[0050] When the steel bars are being guided, the staff inserts the steel bars into the bent pipe 53. At this time, the steel bars pass through the guide frame group 52. At this time, the steel bars are erected above the beam frame 51. When the steel bars are placed above the beam frame 51, the pad 56 below is squeezed. At this time, the pad 56 and the extrusion pad 55 under the support plate 54 are deformed by the weight of the steel bars. When the steel bars shake when being pushed, the beam frame 51 provides stable support for the steel bars to prevent the shaking of the steel bars during feeding from affecting the guiding accuracy.

[0051] The steel bars are mounted on the beam 51, and pass through the bent pipe 53 and the positioning through plate 523 to extend into the positioning assembly 6 to guide the steel bars. When the steel bars are placed on the top of the beam 51 and pushed into the positioning assembly 6, the steel bars are prone to shaking during guidance due to their long length. At this time, the shaking steel bars squeeze the pad 56, so that the hollow pad 553 installed between the pad 56 and the support plate 54 is squeezed and deformed. At this time, the curved piece 554 is squeezed to drive the curved piece 554 to rotate on the surface of the rotating rod 552 to cushion the shaking steel bars.

[0052] The staff rotates the clamping block 61 so that the slider 65 slides in the guide groove 62. At this time, the clamping block 61 rotates on the surface of the circular shaft 64 to adjust the distance between the clamping blocks 61 on both sides to clamp and fix the steel bar. At this time, the staff adjusts the swivel seat 73 to the side of the circular shaft 64 so that the torsion plate 72 is offset from the swivel seat 73, so that the swivel seat 73 is adjusted to one side of the steel bar.

[0053] The steel bars are clamped in the clamping blocks 61 on both sides, and the staff turns the handle 71 to make the torsion plate 72 rotate on the outside of the positioning shaft 63, and the swivel seat 73 rotates until it contacts the steel bars. Then the staff twists the handle 71 and makes the limit plate 75 clamp on the surface of the steel bars to bend the steel bars to avoid the deviation of the steel bars when twisting, which affects the bending curvature of the steel bars. The steel bars are accurately fixed at the position to be bent through the guide frame group 52 and the extrusion pad 55 to ensure that the steel bars will not shift or shake during the bending process, thereby ensuring the bending accuracy.
