Description

Technical Field

[0001] The invention relates to a steel bar bending device for steel structure detection, belonging to the technical field of steel bar detection equipment. Background Art

[0002] When testing the performance of steel bars, steel bars are usually cut to a fixed length and bent to a certain angle or radius using a steel bar bending tester. After bending, they are heated at a constant temperature and bent a second time to observe whether cracks or deformation occur. The bending test can evaluate the flexibility and cold bending properties of the steel bars.

[0003] Chinese patent document CN220626058U discloses a rebar bending device for inspecting building steel structures, comprising a pedestal, a bending force member, a swing arm assembly, and a screw adjuster. The pedestal has first and second panels fixed to its top and rear sides; a side seat fixed to one end of the first and second panels; the bending force member comprises a turntable having multiple through-holes, one of which is movably embedded with a force-bearing column; a cylinder seat fixed at the center of the turntable; a ring plate integrally formed at the top of the cylinder seat; the turntable is connected to a reduction motor power assembly on the inside of the pedestal; the swing arm assembly comprises a swing arm hinged to the first panel; and a straight groove is provided on the swing arm that movably engages with the ring plate. The straight groove of the swing arm assembly movably engages with the ring plate to form a closed cavity structure, which can movably limit the bending position of the rebar, improve the safety of the rebar bending, and prevent the rebar from sliding up and down excessively, thereby ensuring the stability of the rebar bending.

[0004] However, the device clamps and bends the steel bars through the load-bearing column and the cylinder seat. In the process of the load-bearing column and the cylinder seat clamping and pulling the steel bars forward for bending, the steel bars are prone to slip relative to the load-bearing column or the cylinder seat, thereby affecting the bending effect and bending stability of the steel bars. At the same time, there is also a safety hazard that the steel bars will break away from the device and pop out and injure the staff during the bending process. Summary of the Invention

The free end of the spring piece and the end of the compression spring away from the spring piece both rest on the vertical plate. Under the elastic force of the spring piece and the compression spring, the moving block tends to move toward the fixed block.

[0015] The moving block is provided with a plurality of anti-skid grooves at intervals at both ends of the arc groove D, and a flexible rubber anti-skid plate is provided on the arc surface of the arc groove D.

[0023] The beneficial effects of the present invention are:

[0024] 1. During the steel bar bending process, the clamping and bending mechanism continuously clamps the front end of the steel bar to be bent so that it moves forward and bends. This prevents the steel bar to be bent from slipping relative to the clamping and bending mechanism or the forming wheel, thereby ensuring the bending effect and bending stability of the steel bar. At the same time, it eliminates the potential safety hazard of the steel bar to be bent escaping from the bending device and injuring the workers during the bending process.

[0025] 2. The present invention positions and supports the tail of the steel bar to be bent by the arc groove B on the tail limiting support block, and assists in supporting the tail of the steel bar to be bent by the support plate. On the one hand, it can prevent the tail of the steel bar to be bent from bending downward, which would have an adverse effect on the steel bar bending effect; on the other hand, it can prevent the tail of the steel bar to be bent from swinging significantly during the bending process, thereby reducing the potential safety hazard of the steel bar tail swinging significantly and injuring workers, and improving the safety of the device.

[0026] 3. The middle part of the T-shaped slide bar is slidably connected to the T-shaped slide groove on the control block, so that the distance between the tail limit support block and the clamping bending mechanism can be adjusted according to the actual length of the steel bar to be bent, thereby enabling the tail limit support block to adapt to the effective positioning and support of the tail of the steel bar to be bent of different lengths, significantly improving the practicality of the device.

[0027] 4. The front end of the steel bar to be bent is clamped and supported by the clamping and bending mechanism, the middle part is limited and supported by the arc groove A on the control block and the arc groove C on the forming wheel, and the tail is positioned and supported by the tail limiting support block and the support plate. It can be seen that the front end, middle part and tail of the steel bar to be bent are all well supported, which significantly improves the stability of the steel bar to be bent during the bending process, ensures the bending effect of the steel bar to be bent, and effectively eliminates the safety hazard of the steel bar to be bent detaching from the bending device and bouncing out during the bending process to injure the workers.

[0028] 5. Under the elastic force of the shrapnel and the compression spring, part of the moving block extends to the inner side of the U-shaped block through the notch, that is, the arc groove D moves to the inner side of the U-shaped block, and the central axis of the arc groove D is misaligned with the central axis of the inner arc of the U-shaped block; in the process of the clamping and bending mechanism clamping the front end of the steel bar to be bent and pulling the steel bar to be bent forward for bending, the front end of the steel bar to be bent is simultaneously inside the arc groove D and the inner arc of the U-shaped block. Therefore, the staggered arc groove D and the inner arc of the U-shaped block can apply a larger friction force to the front end of the steel bar to be bent, thereby preventing the steel bar to be bent from slipping relative to the clamping and bending mechanism or the forming wheel during the bending process, thereby ensuring the bending effect and bending stability of the steel bar.

[0029] 6. The flexible rubber anti-slip plate and multiple anti-slip grooves further increase the friction or bite force between the arc groove D and the steel bar to be bent, thereby preventing the steel bar to be bent from slipping relative to the clamping bending mechanism or forming wheel during the bending process, thereby ensuring the bending effect and bending stability of the steel bar.

[0030] 7. When the bending drive assembly drives the forming wheel to rotate clockwise through the push-pull arm, the forming wheel drives the C-shaped plate and the L-shaped push plate to rotate together. The L-shaped push plate pushes the load-bearing plate toward the control block, thereby cutting the steel bar through the cooperation of the cutting knife on the load-bearing plate and the control block, so that the bending device has both bending and cutting functions.

DETAILED DESCRIPTION

[0043] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0044] like Figures 1 to 8As shown, a steel bar bending device for steel structure inspection according to the present invention comprises a support frame 1, a position-limiting support mechanism, a forming wheel 101, a clamping and bending mechanism 2, and a bending drive assembly 102. The support frame 1 is provided with a support arm 4, and the forming wheel 101 is rotatably arranged on the support arm 4 at one end away from the support frame 1. The position-limiting support mechanism is arranged on the support arm 4 and is located between the support frame 1 and the forming wheel 101. The clamping and bending mechanism 2 is arranged on the forming wheel 101, and the bending drive assembly 102 is arranged on the support frame 1 and connected to the forming wheel 101 through a push-pull arm 103. When in use, the position-limiting support mechanism supports the steel bar to be bent and limits the position of the steel bar to be bent in the radial direction. The clamping and bending mechanism 2 clamps the front end of the steel bar to be bent, and the bending drive assembly 102 drives the clamping and bending mechanism 2 to pull the steel bar to be bent forward, and the clamping and bending mechanism 2 cooperates with the forming wheel 101 to complete the bending work of the steel bar to be bent. Since during the steel bar bending process, the clamping and bending mechanism 2 continuously clamps the front end of the steel bar to be bent so that it moves forward and bends, it can prevent the steel bar to be bent from slipping relative to the clamping and bending mechanism 2 or the forming wheel 101, thereby ensuring the bending effect and bending stability of the steel bar, and at the same time eliminating the safety hazard of the steel bar to be bent detaching from the bending device and popping out during the bending process to injure the staff.

[0045] The limit support mechanism includes a control block 104 and a T-shaped slide bar 106. The control block 104 is arranged on the inner side of the support arm 4. A T-shaped slide groove is opened on the side of the control block 104 close to the support frame 1, and an arc groove A is opened on the side close to the forming wheel 101. The middle part of the T-shaped slide bar 106 is slidably connected to the T-shaped slide groove on the control block 104. One end of the T-shaped slide bar is provided with a limit plate, and the other end is provided with a tail limit support block 107;

[0046] The tail limit support block 107 is provided with a control handle 108. The tail limit support block 107 is provided with an arc-shaped groove B, which is coaxially arranged with the arc-shaped groove A. A support plate 109 is provided on the side of the tail limit support block 107 where the arc-shaped groove B is provided. The support plate 109 is located below the arc-shaped groove B and is tangent to the arc-shaped groove B. When in use, the arc-shaped groove A on the control block 104 cooperates with the arc-shaped groove C on the forming wheel 101 to limit the position of the steel bar to be bent in the radial direction.

[0047] Common steel bar bending devices for steel structure inspection do not constrain the tail of the steel bar to be bent. Therefore, when the length of the steel bar to be bent is long, its tail will bend downward under the action of its own weight, causing its front end to tilt upward, which will affect the bending effect of the steel bar. Moreover, under the bending stress of the steel bar, the tail of the steel bar will swing greatly, posing a safety hazard of the steel bar tail swinging and injuring the staff. To this end, the present invention positions and supports the tail of the steel bar to be bent by the arc groove B on the tail limiting support block 107, and assists in supporting the tail of the steel bar to be bent by the support plate 109. On the one hand, it can prevent the tail of the steel bar to be bent from bending downward, which will have an adverse effect on the steel bar bending effect; on the other hand, it can prevent the tail of the steel bar to be bent from swinging greatly during the bending process, reducing the safety hazard of the steel bar tail swinging greatly and injuring the staff, and improving the safety of the device.

[0048] The middle part of the T-shaped slide bar 106 is slidably connected to the T-shaped slide groove on the control block 104, so that the distance between the tail limit support block 107 and the clamping bending mechanism 2 can be adjusted according to the actual length of the steel bar to be bent, thereby enabling the tail limit support block 107 to adapt to the effective positioning and support of the tails of the steel bars to be bent of different lengths, significantly improving the practicality of the device.

[0049] The front end of the steel bar to be bent is clamped and supported by the clamping bending mechanism 2, the middle part is limited and supported by the arc groove A on the control block 104 and the arc groove C on the forming wheel 101, and the tail is positioned and supported by the tail limiting support block 107 and the support plate 109; it can be seen that the front end, middle part and tail of the steel bar to be bent are all well supported, which significantly improves the stability of the steel bar to be bent during the bending process, ensures the bending effect of the steel bar to be bent, and effectively eliminates the safety hazard of the steel bar to be bent detaching from the bending device and popping out during the bending process to injure the staff.

[0050] A central shaft 5 is fixedly provided on one end of the support arm 4 away from the support frame 1, and a forming wheel 101 is rotatably sleeved on the central shaft 5, and an arc-shaped groove C is opened on the forming wheel 101 along the circumference;

[0051] The bending drive assembly 102 is a hydraulic cylinder, one end of which is hinged to the support frame 1, and the other end is hinged to one end of the push-pull arm 103;

[0052] The end of the push-pull arm 103 away from the bending drive assembly 102 is rotatably connected to the central axis 5, and the middle part of the push-pull arm 103 is connected to the forming wheel 101 through the connecting shaft C6. When in use, the hydraulic cylinder drives the forming wheel 101 to rotate around the central axis 5 through the push-pull arm 103.

[0053] The clamping and bending mechanism 2 includes a U-shaped block 203, a fixed block 209 and a clamping assembly. A slot 210 is provided in the middle of the U-shaped block 203. The fixed block 209 is located on the inner side of the U-shaped block 203. The fixed block 209 and the U-shaped open end of the U-shaped block 203 are fixedly connected to the forming wheel 101 through a connecting shaft A211. The clamping assembly is provided on the U-shaped block 203, and part of the clamping assembly extends to the inner side of the U-shaped block 203 through the slot 210.

[0054] The clamping assembly includes a moving block 205 and two vertical plates 204. The two vertical plates 204 are symmetrically arranged on the U-shaped block 203. An arc groove D is opened on the side of the moving block 205 close to the fixed block 209, and a T-shaped block 207 is provided on the top and bottom of the moving block 205. A spring 208 is provided on the T-shaped block 207. The spring 208 is connected to the T-shaped block 207 through two round rods 212 arranged side by side. A compression spring 213 is set on the round rod 212. The T-shaped block 207 at the top of the moving block 205 is provided with a compression spring 213. The shaped block 207 and the two round rods 212 pass through one of the vertical plates 204 and are slidably connected to the vertical plate 204. The moving block 205 located at the bottom of the moving block 205 and the two round rods 212 pass through the other vertical plate 204 and are slidably connected to the vertical plate 204. The free end of the spring 208 and the end of the compression spring 213 away from the spring 208 are both against the vertical plate 204. Under the elastic force of the spring 208 and the compression spring 213, the moving block 205 tends to move toward the fixed block 209. When in use, under the elastic force of the spring piece 208 and the compression spring 213, the moving block 205 partially extends to the inner side of the U-shaped block 203 through the notch 210, that is, the arc groove D moves to the inner side of the U-shaped block 203, and the center axis of the arc groove D is misaligned with the center axis of the inner arc of the U-shaped block 203; in the process of the clamping and bending mechanism 2 clamping the front end of the steel bar to be bent and pulling the steel bar to be bent forward for bending, the front end of the steel bar to be bent is simultaneously inside the arc groove D and the inner arc of the U-shaped block 203, so the misaligned arc groove D and the inner arc of the U-shaped block 203 can apply a larger friction force to the front end of the steel bar to be bent, thereby preventing the steel bar to be bent from slipping relative to the clamping and bending mechanism 2 or the forming wheel 101 during the bending process, thereby ensuring the bending effect and bending stability of the steel bar.

[0055] The movable block 205 is provided with a plurality of anti-skid grooves 214 at intervals at both ends of the arcuate groove D, and a flexible rubber anti-skid plate 206 is provided on the arcuate surface of the arcuate groove D. The flexible rubber anti-skid plate 206 and the plurality of anti-skid grooves 214 further enhance the friction or engagement force between the arcuate groove D and the steel bar to be bent, thereby preventing the steel bar to be bent from slipping relative to the clamping bending mechanism 2 or the forming wheel 101 during the bending process, thereby ensuring the bending effect and stability of the steel bar.

[0056] An angle indicator disc 7 is provided on the central shaft 5 below the forming wheel 101, and an angle mark is provided on the angle indicator disc 7;

[0057] The fixing block 209 is clamped with a clamping block 201, and an L-shaped pointer 202 is provided at the bottom of the clamping block 201. It is convenient to determine the actual bending angle of the steel bar to be bent by the relative position of the pointer 202 and the angle mark on the angle indicator plate 7.

[0058] It also includes a steel bar cutting mechanism 3, which is arranged on the forming wheel 101 and is movably connected to the limiting support mechanism.

[0059] The steel bar cutting mechanism 3 includes a cutting drive assembly and a cutting execution assembly. The cutting drive assembly is fixed on the forming wheel 101, and the cutting execution assembly is slidably connected to the limiting support mechanism and the cutting drive assembly.

[0060] The cutting drive assembly includes a C-shaped plate 301 and an L-shaped push plate 303. The two C-shaped ends of the C-shaped plate 301 are fixed to the forming wheel 101 through a latch 302. Two connecting shafts B304 are symmetrically and rotatably provided on the C-shaped plate 301. One end of the L-shaped push plate 303 is connected to the middle of the C-shaped plate 301.

[0061] The top and bottom of the control block 104 are both provided with rectangular sliding grooves 105;

[0062] The cutting execution assembly includes a force-bearing plate 306, with guide rods A305 and B308 provided at the top and bottom of the force-bearing plate 306. The guide rods A305 at the top and bottom of the force-bearing plate 306 pass through the two connecting shafts B304 on the C-shaped plate 301 in a one-to-one correspondence, and the guide rods A305 and the connecting shafts B304 are slidably connected. The guide rods B308 at the top and bottom of the force-bearing plate 306 are slidably connected to the rectangular slides 105 at the top and bottom of the control block 104 in a one-to-one correspondence. A cutting knife 307 is provided on the side of the force-bearing plate 306 facing away from the L-shaped push plate 303. Figure 1 and Figure 7 As shown, when the bending drive assembly 102 drives the forming wheel 101 to rotate clockwise through the push-pull arm 103, the forming wheel 101 drives the C-shaped plate 301 and the L-shaped push plate 303 to rotate together, and the L-shaped push plate 303 pushes the force-bearing plate 306 to move toward the control block 104, so that the cutting knife 307 on the force-bearing plate 306 cooperates with the control block 104 to cut the steel bar, thereby making the bending device have both bending and cutting functions.

[0063] The working principle of the steel bar bending device for steel structure inspection provided by the present invention is as follows:

[0064] The front end of the steel bar to be bent is passed through the gap formed by the arc groove A on the control block 104 and the arc groove C on the forming wheel 101, and is inserted into the arc on the inner side of the U-shaped block 203 in the clamping and bending mechanism 2, and the arc groove D on the moving block 205, so as to clamp the front end of the steel bar to be bent by the U-shaped block 203 and the moving block 205; then, holding the control handle 108, the tail limit support block 107 is moved to the appropriate position, so as to position and support the tail of the steel bar to be bent by the arc groove B on the tail limit support block 107.

[0065] Next, the bending drive assembly 102 is controlled to drive the push-pull arm 103 to push the forming wheel 101 to rotate clockwise. While rotating, the forming wheel 101 drives the clamping and bending mechanism 2 to rotate together, so that the bending work of the steel bar to be bent is completed through the cooperation of the clamping and bending mechanism 2 and the forming wheel 101.

[0066] When it is necessary to cut the steel bars, the steel bar cutting mechanism 3 is installed in advance on the forming wheel 101 and the control block 104. When the forming wheel 101 rotates clockwise, it drives the C-shaped plate 301 and the L-shaped push plate 303 to rotate together. The L-shaped push plate 303 pushes the load-bearing plate 306 toward the control block 104, so that the cutting blade 307 on the load-bearing plate 306 cooperates with the control block 104 to cut the steel bars.
