Description

Technical Field

[0001] The present application relates to the field of steel bar straightening, and in particular to a steel bar straightening device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. The cross-section of the rebar is circular, and sometimes square with rounded corners. For easy transportation, the rebar is generally bent into rolls and then transported. The rebar is then reinforced after being transported to the construction site.

[0003] Rebar processing generally goes through four steps: rust removal, straightening, cutting and forming. It is mainly used for various large, heavy, light thin-walled and high-rise building structures. It is divided into three types: round steel bars, ribbed steel bars and twisted steel bars. When straightening steel bars, they are generally straightened directly with a straightener. The operation method is to find the end of the rolled steel bar, and then send the end of the steel bar into the steel bar straightener. The steel bar passes through the steel bar straightener and is straightened.

[0004] When straightening coiled steel bars, they are generally straightened to a longer length, then cut and continue to straighten them to make the coiled steel bars into longer strips. The longer steel bars are then cut according to construction needs. In the process of straightening the steel bars, since the discharge port of the straightener is at a height from the ground, when one end of the steel bar comes out of the straightener, the steel bar is affected by its own gravity, and one end of the steel bar may hit the ground while the other end is still on the modulator, causing a height difference between the two ends of the steel bar. The steel bar is affected by its own weight, and the steel bar may bend, and the end of the steel bar that hits the ground may stick to the ground, making it unable to move. Utility Model Content

[0005] The purpose of the present application is to solve the problem that in the process of straightening the steel bars proposed in the above-mentioned background technology, since the discharge port of the straightener is at a height from the ground, when one end of the steel bar comes out of the straightener, the steel bar is affected by its own gravity, and one end of the steel bar may hit the ground while the other end is still on the modulator, causing a height difference between the two ends of the steel bar. The steel bar is affected by its own weight, and the steel bar may bend, and the end of the steel bar that hits the ground may stick to the ground, making it unable to move. The present application provides a steel bar straightening device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A steel bar straightening device comprises a straightening workbench, on which a straightener is installed, one end of the straightener is provided with a feed port, the other end of the straightener is provided with a discharge port, two symmetrical discharge limit plates are fixed to the end of the straightener close to the discharge port, the end of the straightener close to the discharge limit plate is provided with a discharge mechanism, and the end of the straightener close to the discharge limit plate is provided with a receiving mechanism.

[0008] By adopting the above technical scheme, the straightened steel bars come out from the discharge port, and then enter the discharge mechanism under the restriction of the discharge limit plate. When the length of the steel bars in the discharge mechanism reaches the required length, the straightener cuts the steel bars, and then the discharge mechanism transfers the straightened steel bars to the receiving mechanism, and then the discharge mechanism continues to receive the straightened steel bars. After the steel bars in the receiving mechanism are gathered to a large number, the steel bars in the receiving mechanism are bundled, thereby reducing the possibility of bending of the straightened steel bars due to excessive length, one end of which is on the ground and the other end is still on the straightener, and the steel bars are pressed down due to their own weight. At the same time, it reduces the possibility that one end of the steel bar may directly hit the ground, affecting the normal delivery of the steel bars by the straightener.

[0009] Furthermore, the discharging mechanism includes a discharging rod arranged at one end of the straightener near the discharge port, one end of the discharging rod is rotatably connected to the straightener, a support frame is arranged at the end of the discharging rod away from the discharging rod, the support frame is rotatably connected to the end of the discharging rod away from the straightener, four circumferentially distributed discharging frames are fixed on the discharging rod, a discharging motor is fixed on the support frame, the output end of the discharging motor passes through the support frame and is fixedly connected to the discharging rod, a controller is installed in the discharging motor, and a trigger flipping assembly is arranged on the discharging rod.

[0010] By adopting the above technical solution, the steel bars coming out of the discharge port of the straightener are moved between the adjacent discharge racks on the discharge rod. When the end of the steel bar hits the trigger flip assembly, the discharge motor drives the discharge rod to rotate, allowing the steel bars between the adjacent discharge racks to fall, thereby reducing the possibility of the end of the straightened steel bar being stuck on the ground due to the straightening being too long, affecting the movement of the steel bar, and reducing the possibility of the steel bar being bent due to its own weight due to the height difference between one end of the steel bar being on the ground and the other end on the straightener.

[0011] Furthermore, the trigger flip assembly includes a sliding block slidably connected to the discharge rod, the sliding block is in a cross shape, four support plates are fixed on the sliding block, and pressure sensors are fixed on the support plates.

[0012] By adopting the above technical solution, the steel bars are moved between adjacent unloading racks. When the end of the steel bar hits the pressure sensor on the support plate, the unloading motor is triggered to drive the unloading rod. At the same time, the straightener stops straightening the steel bars and cuts the steel bars, allowing the unloading rack on the unloading rod to rotate. This can reduce the possibility that the straightener continues to straighten the steel bars when the unloading rack is moving the steel bars, causing the steel bars to get stuck with the unloading rack.

[0013] Furthermore, a protective pad is fixed on the pressure sensor, and the protective pad is a rubber pad.

[0014] By adopting the above technical solution, when the end of the steel bar moves between adjacent material racks, the steel bar will contact the protective pad and the pressure sensor, thereby protecting the pressure sensor and reducing the possibility of the steel bar end wearing the pressure sensor.

[0015] Furthermore, a support block is fixed on the sliding block, the support block passes through the discharge rod, a bidirectional threaded rod is rotatably connected to the support block, and two symmetrical locking blocks are threadedly connected to the bidirectional threaded rod.

[0016] By adopting the above technical solution, the sliding block drives the support plate to move to the corresponding position on the discharge rod, and then the bidirectional threaded rod is twisted to make the two locking blocks on the bidirectional threaded rod contact the discharge rod to fix the sliding block, so that the position of the pressure sensor on the support block can be adjusted according to the required length of the steel bar.

[0017] Furthermore, the unloading rack is provided with a plurality of evenly distributed support shafts, and the support shafts are rotatably connected to the unloading rack.

[0018] By adopting the above technical solution, when the steel bars move, the support shaft rotates on the unloading rack, thereby reducing the possibility of friction between the steel bars and the unloading rack.

[0019] Furthermore, the receiving mechanism includes a receiving inclined plate arranged on one side of the discharge rod, a receiving block is fixed on the receiving inclined plate, a receiving groove is opened on the receiving block, a receiving pad is fixed in the receiving groove, and two symmetrical support seats are fixed on the receiving inclined plate, and the support seats are in contact with the ground.

[0020] By adopting the above technical solution, when the steel bars fall from between adjacent discharge racks, they fall directly onto the receiving inclined plate, and then roll from the receiving inclined plate into the receiving groove of the receiving block, thereby facilitating the collection of the straightened steel bars.

[0021] Furthermore, the receiving block is provided with a plurality of binding grooves, and the binding grooves penetrate the receiving block.

[0022] By adopting the above technical solution, the binding rope can be passed through the binding groove on the receiving block, and then the straightened steel bars can be bound by the binding rope, so that the straightened steel bars can be collected conveniently and the collected steel bars can be bound and moved conveniently.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, the sliding block is fixed. When the steel bar passes through the straightener and comes out of the discharge port of the straightener, the steel bar moves under the restriction of the two discharge limit plates, and then the steel bar moves between the two discharge racks on the discharge rod, and the steel bar moves under the support of the two discharge racks. When the end of the steel bar hits the protective pad and the pressure sensor is pressurized, the straightener stops straightening the steel bar and then cuts the steel bar. At the same time, the discharge motor drives the discharge rod to rotate, and the discharge rod drives the discharge rack to rotate. The steel bar located between adjacent discharge racks rotates with the discharge rod under the restriction of the discharge rack, and then the steel bar falls from between the adjacent discharge racks, thereby achieving the purpose of reducing the possibility that the straightener cannot normally deliver the steel bar due to one end of the straightened steel bar being stuck on the ground due to the long straightening steel bar, and at the same time reducing the possibility that the steel bar is bent due to the influence of its own gravity when one end of the steel bar is on the ground and the other end is on the straightener.

[0025] 2. In the present application, when the straightened steel bars are supported by the discharge rod and move along with the adjacent discharge racks, when the discharge racks are tilted downward, the straightened steel bars fall from between the adjacent discharge racks, and then fall on the receiving inclined plate, and then the steel bars roll from the receiving inclined plate to the receiving groove passed by the receiving plate, and then the receiving pads in the receiving groove support the steel bars, and then after the steel bars in the receiving groove on the receiving block are gathered together, the binding rope can be passed through the bundling groove on the receiving block, and then the straightened steel bars can be bundled with the binding rope, thereby achieving the purpose of facilitating the collection of the straightened steel bars and facilitating the bundling and movement of the collected steel bars.

[0032] The following is combined with Figure 1 —4 Provide further details of this application.

[0033] The embodiment of the present application discloses a steel bar straightening device.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A steel bar straightening device comprises a straightening workbench 1, on which a straightener 2 is installed, a feed port 3 is provided at one end of the straightener 2, a discharge port 4 is provided at the other end of the straightener 2, two symmetrical discharge limit plates 7 are fixed at one end of the straightener 2 close to the discharge port 4, a discharge mechanism 5 is provided at one end of the straightener 2 close to the discharge limit plate 7, and a receiving mechanism 6 is provided at one end of the straightener 2 close to the discharge limit plate 7.

[0035] When using the steel bar straightening device, first put the steel bar coil on one end of the straightening workbench 1, then find out the end of the steel bar coil, and then feed it into the feeding port 3 of the straightener 2. The straightener 2 straightens the bent steel bars, and the straightened steel bars come out from the discharging port 4, and then enter the discharging mechanism 5 under the restriction of the discharging limit plate 7. When the length of the steel bars in the discharging mechanism 5 reaches the required length, the straightener 2 cuts the steel bars, and then the discharging mechanism 5 transfers the straightened steel bars to the receiving mechanism 6, and then the discharging mechanism 5 continues to receive the straightened steel bars. After the steel bars in the receiving mechanism 6 are gathered to a large number, the steel bars in the receiving mechanism 6 are bundled. By using the discharging mechanism 5 to receive the straightened steel bars, the possibility of bending of the straightened steel bars due to excessive length, one end of which is on the ground and the other end is still on the straightener 2, and the weight of the steel bars themselves is pressed down, can be reduced. At the same time, the possibility that one end of the steel bar may directly hit the ground, affecting the normal delivery of the steel bars by the straightener 2, can be reduced.

[0036] Reference Figure 2 , Figure 3 and Figure 4The discharging mechanism 5 includes a discharging rod 51 arranged at one end of the straightener 2 close to the discharge port 4, one end of the discharging rod 51 is rotatably connected to the straightener 2, a support frame 52 is arranged at the end of the discharging rod 51 away from the discharging rod 51, the support frame 52 is rotatably connected to the end of the discharging rod 51 away from the straightener 2, four circumferentially distributed discharging frames 53 are fixed on the discharging rod 51, a discharging motor 54 is fixed on the support frame 52, the output end of the discharging motor 54 passes through the support frame 52 and is fixedly connected to the discharging rod 51, a controller is installed in the discharging motor 54, and a trigger flipping component 55 is arranged on the discharging rod 51.

[0037] In addition, the trigger flip assembly 55 includes a sliding block 551 slidably connected to the discharge rod 51 , the sliding block 551 is cross-shaped, four support plates 552 are fixed on the sliding block 551 , and a pressure sensor 553 is fixed on the support plate 552 .

[0038] In addition, a protection pad 554 is fixed on the pressure sensor 553, and the protection pad 554 is a rubber pad.

[0039] Moreover, a support block 557 is fixed on the sliding block 551 , and the support block 557 penetrates the discharge rod 51 . A bidirectional threaded rod 556 is rotatably connected to the support block 557 , and two symmetrical locking blocks 555 are threadedly connected to the bidirectional threaded rod 556 .

[0040] First, according to the required length of a single straightened steel bar, directly move the sliding block 551, let the sliding block 551 drive the support plate 552 to move to the corresponding position on the feeding rod 51, and then twist the bidirectional threaded rod 556, so that the two locking blocks 555 on the bidirectional threaded rod 556 abut against the feeding rod 51, and fix the sliding block 551. When the steel bar passes through the straightener 2 and comes out of the discharge port 4 of the straightener 2, the steel bar moves under the restriction of the two discharge limit plates 7, and then the steel bar moves between the two feeding racks 53 on the feeding rod 51, and the steel bar moves under the support of the two feeding racks 53. When the end of the steel bar abuts against the protective pad 554 and the pressure sensor 553 is pressurized, the straightener 2 stops straightening the steel bar, and then cuts the steel bar. At the same time, the feeding motor 54 drives the feeding rod 51 to rotate, and the feeding rod 51 drives the discharge rack 53 to rotate, and the steel bars located between adjacent discharge racks 53 rotate with the discharge rod 51 under the restriction of the discharge rack 53, and then the steel bars fall from between the adjacent discharge racks 53 onto the receiving mechanism 6, and then the straightener 2 continues to straighten the steel bars, and the straightened steel bars are moved to between the adjacent discharge racks 53 again, and then flipped onto the receiving mechanism 6 by the discharge rack 53. The straightened steel bars coming out of the straightener 2 are supported by the discharge rack 53 on the discharge rod 51, so that the steel bars are kept in the same horizontal plane, and then the steel bars are moved to the receiving mechanism 6, thereby reducing the possibility that the straightener 2 cannot normally deliver the steel bars due to one end of the straightened steel bars being stuck on the ground due to the straightening steel bars being too long, and at the same time, reducing the possibility that the steel bars are bent due to the influence of their own gravity with one end of the steel bars on the ground and the other end on the straightener 2.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The unloading rack 53 is provided with a plurality of evenly distributed support shafts 56, which are rotatably connected to the unloading rack 53. When the straightened steel bars move between two adjacent unloading racks 53, the support shafts 56 on the unloading rack 53 abut against the steel bars, and when the steel bars move, the support shafts 56 rotate on the unloading rack 53. By supporting the moving steel bars with the support shafts 56 rotatably connected to the unloading rack 53, the possibility of friction between the steel bars and the unloading rack 53 can be reduced.

[0042] Reference Figure 1 and Figure 2 The receiving mechanism 6 includes a receiving inclined plate 61 arranged on one side of the discharge rod 51, a receiving block 62 is fixed on the receiving inclined plate 61, a receiving groove is opened on the receiving block 62, a receiving pad 63 is fixed in the receiving groove, and two symmetrical supporting seats 64 are fixed on the receiving inclined plate 61, and the supporting seats 64 are in contact with the ground.

[0043] In addition, a plurality of binding grooves 65 are formed on the receiving block 62 , and the binding grooves 65 penetrate the receiving block 62 .

[0044] When the straightened steel bars move along with the adjacent discharge racks 53 under the support of the discharge rod 51, when the discharge rack 53 tilts downward, the straightened steel bars fall from between the adjacent discharge racks 53, and then fall on the receiving inclined plate 61, and then the steel bars roll from the receiving inclined plate 61 to the receiving groove passed by the receiving plate, and then the receiving pad 63 in the receiving groove supports the steel bars, and then after the steel bars in the receiving groove on the receiving block 62 are gathered together, the binding rope can be passed through the bundling groove 65 on the receiving block 62, and then the straightened steel bars can be bundled with the binding rope, and the straightened steel bars can be concentrated in the receiving groove by using the receiving inclined plate 61 and the receiving block 62, so that the straightened steel bars can be collected conveniently, and the collected steel bars can be bundled and moved conveniently.

[0045] Working principle: When using the steel bar straightening device, first put the steel bar coil on one end of the straightening workbench 1, then find the end of the steel bar coil, and then feed it into the feed port 3 of the straightener 2. The straightener 2 straightens the bent steel bars, and the straightened steel bars come out from the discharge port 4. First, according to the length of a single straightened steel bar required, directly move the sliding block 551, let the sliding block 551 drive the supporting plate 552 to move to the corresponding position on the discharge rod 51, and then twist the bidirectional threaded rod 556, so that the two locking blocks 555 on the bidirectional threaded rod 556 are in contact with the discharge rod 51, and the sliding block 551 is fixed. When the steel bar passes through the straightener 2 and comes out of the discharge port 4 of the straightener 2, the steel bar moves under the restriction of the two discharge limit plates 7, and then the steel bar moves between the two discharge racks 53 on the discharge rod 51, and the steel bar moves under the support of the two discharge racks 53. When the end of the steel bar touches the protective pad 554 and the pressure sensor 553 is under pressure, the straightener 2 stops straightening the steel bar and then cuts the steel bar. At the same time, the feeding motor 54 drives the feeding rod 51 to rotate, and the feeding rod 51 drives the feeding rack 53 to rotate. The steel bars between adjacent feeding racks 53 rotate with the feeding rod 51 under the restriction of the feeding rack 53. When the feeding rack 53 tilts downward, the straightened steel bars fall from between the adjacent feeding racks 53, and then fall on the receiving inclined plate 61, and then the steel bars roll from the receiving inclined plate 61 to the receiving groove passed by the receiving plate, and then the receiving pad 63 in the receiving groove supports the steel bars. After the steel bars in the receiving groove on the receiving block 62 are gathered together, the binding rope can be used to pass through the binding groove 65 on the receiving block 62, and then the straightened steel bars are bound by the binding rope.
