Description

Technical Field

[0001] This utility model relates to the field of prestressed steel bar production technology, and in particular to a straightening device for prestressed steel bar production. Background Technology

[0002] Prestressed steel bars are a type of reinforcing steel bar. They are specialized devices that, after treatment, are subjected to prestressing tension and anchored within concrete. Typically, the tension generated by tensioning the prestressed steel bars creates pressure within the concrete, thereby enhancing the strength and stability of the concrete structure. During the production of prestressed steel bars, they require straightening treatment using a straightening device to eliminate bending deformation that occurs during production and ensure the straightness of the prestressed steel bars meets production requirements.

[0003] In related technologies, after the prestressed bar is placed into the straightening device, the device can only straighten the prestressed steel bar in the straight direction, but cannot effectively straighten its transverse curvature, that is, it cannot effectively correct its curvature in the perpendicular direction (i.e., the other direction) of the initial straightening direction. Therefore, after straightening once, it is necessary to manually adjust the direction and straighten again, resulting in low straightening efficiency and difficulty in guaranteeing straightening accuracy. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a straightening device for the production of prestressed steel bars. The steel bars are clamped and fixed by a clamping component, and then the steel bars are rotated by a driving component. When the steel bars are rotated into position, the straightening component straightens the steel bars in the lateral direction, thereby realizing the automatic straightening of the prestressed steel bars in all directions, improving the straightening efficiency and ensuring the straightening accuracy.

[0006] To achieve the above objectives, this utility model proposes a straightening device for prestressed steel bar production, comprising a frame, two sets of conveying components, a straightening component, a flipping device, and a conveying motor. The two sets of conveying components are respectively mounted on the frame and symmetrically located on both sides of the straightening component. The straightening component is mounted on the frame. The conveying motor is mounted on the frame and drives the two sets of conveying components to rotate synchronously. The flipping device includes a clamping component, a driving component, a support base, and a base. The clamping component is rotatably disposed inside the support base. The driving component is disposed on the support base and drives the clamping component to rotate synchronously. The support base is movably disposed on the base and can be adjusted along the height direction of the base.

[0007] In addition, the straightening device for producing prestressed steel bars according to the present invention may also have the following additional technical features: Specifically, each conveying assembly includes a conveying base, a main conveying wheel, an auxiliary conveying wheel, a mounting base, an elastic element, a pressure plate, and an adjusting screw. The main conveying wheel is rotatably mounted on the conveying base, and the auxiliary conveying wheel is rotatably mounted on the mounting base and is symmetrically arranged vertically with the main conveying wheel. The mounting base is slidably mounted inside the conveying base, and the pressure plate is slidably mounted inside the conveying base and is held in place by the elastic element. The adjusting screw is threaded inside the conveying base and its bottom end is rotatably mounted on the pressure plate.

[0008] Specifically, the straightening assembly includes a straightening seat, an adjusting screw, multiple upper straightening wheels, a lifting seat, and multiple lower straightening wheels. The multiple lower straightening wheels are equidistantly rotatably disposed on the straightening seat, and the multiple upper straightening wheels are equidistantly rotatably disposed on the lifting seat and arranged alternately with the lower straightening wheels. The lifting seat is slidably disposed within the straightening seat, and the adjusting screw is threaded within the straightening seat, with its bottom end rotatably disposed on the lifting seat.

[0009] Specifically, the clamping assembly includes a clamping cylinder, a clamping plate, two side plates, a mounting ring, and a guide sleeve. The two side plates are symmetrically arranged on the mounting ring. The clamping cylinder is disposed on the side plate and its cylinder shaft end is connected to the clamping plate. The mounting ring is disposed on the guide sleeve and communicates with the guide sleeve.

[0010] Specifically, the drive assembly includes a drive motor, a gear ring, and a gear, wherein the gear is disposed on the output shaft of the drive motor and meshes with the outer wall of the gear ring.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention uses a conveying assembly to transport prestressed steel bars to a straightening assembly, which can eliminate the bending deformation of the steel bars during the production process. When the prestressed steel bars are detached from the straightening assembly, one end extends into the interior of the guide sleeve, while the other end is located within a set of conveying assemblies. At this time, the steel bars are clamped and fixed by a clamping assembly, and then the guide sleeve is driven by a driving assembly to achieve the rotation of the steel bars. The straightening assembly then straightens the rotated steel bars, thereby achieving all-round automatic straightening of the prestressed steel bars, improving straightening efficiency and ensuring straightening accuracy.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes a straightening device for producing prestressed steel bars according to an embodiment of the present invention.

[0017] like Figures 1-4 As shown, a straightening device for producing prestressed steel bars according to an embodiment of the present invention includes a frame 1, two sets of conveying components 2, a straightening component 3, a flipping device and a conveying motor 6. The two sets of conveying components 2 are respectively arranged on the frame 1 and symmetrically located on both sides of the straightening component 3. The straightening component 3 is arranged on the frame 1. It should be noted that the straightening assembly 3 is used to straighten the prestressed steel bars, and the conveying assembly 2 is used to convey the prestressed steel bars to ensure that the steel bars can enter the straightening assembly 3 smoothly and continuously for straightening. The conveyor motor 6 is mounted on the frame 1 and drives the two sets of conveyor components 2 to rotate synchronously; It should be noted that the transmission motor 6 serves as the power source for the transmission component 2. It is connected to the transmission component 2 via a transmission belt, thereby enabling the synchronous operation of the two transmission components 2 and ensuring the stability of the prestressed steel bars during the conveying process. The flipping device includes a clamping assembly 4, a driving assembly 5, a support base 7, and a base 8. The clamping assembly 4 is rotatably disposed inside the support base 7, and the driving assembly 5 is disposed on the support base 7 and drives the clamping assembly 4 to rotate synchronously. It should be noted that the flipping device is used to achieve a 90-degree flip of the prestressed steel bar; Specifically, the steel bar is clamped by the clamping component 4, and then driven by the drive component 5, the clamping component 4 drives the steel bar to rotate and flip. After the steel bar is in place, the clamping component 4 releases the steel bar, and then the transmission motor 6 reverses, and the transmission component 2 transmits the steel bar in the opposite direction. At this time, the straightening component 3 straightens the rotated steel bar, thereby improving the straightening efficiency and ensuring the straightening accuracy without manual operation.

[0018] The support base 7 is movably mounted on the base 8 and can be adjusted along the height direction of the base 8; It should be noted that the support base 7 is locked to the base 8 by bolts. The base 8 is provided with a strip groove, and the bolt is located in the strip groove. Thus, when the bolt is loosened, the height of the support base 7 can be adjusted to raise the height of the clamping component 4 and the driving component 5 to accommodate prestressed steel bars of different diameters.

[0019] In one embodiment of this utility model, such as Figures 1-2 As shown, each set of conveying components 2 includes a conveying base 21, a main conveying wheel 22, an auxiliary conveying wheel 23, a mounting base 24, an elastic element 25, a pressure plate 26, and an adjusting screw 27. The main conveying wheel 22 is rotatably mounted on the conveying base 21, and the auxiliary conveying wheel 23 is rotatably mounted on the mounting base 24 and is symmetrically arranged vertically with the main conveying wheel 22. The mounting base 24 is slidably mounted inside the conveying base 21. It should be noted that the conveyor seat 21 is fixedly installed on the frame 1, the auxiliary conveyor wheel 23 rotates on the mounting seat 24 through the bearing, and the main conveyor wheel 22 rotates on the conveyor seat 21 through the bearing. A pulley is provided on its axle, and the pulley is connected to the output shaft of the conveyor motor 6 through the transmission belt. Thus, when the conveyor motor 6 rotates, the main conveyor wheel 22 rotates. When there is a prestressed steel bar inside, the main conveyor wheel 22 drives the prestressed steel bar to move. At the same time, the auxiliary conveyor wheel 23 applies pressure to the prestressed steel bar to ensure the stability of the steel bar during the conveying process. The pressure plate 26 is slidably disposed in the conveyor seat 21 and is pressed against the mounting seat 24 by the elastic element 25. The adjusting screw 27 is threaded in the conveyor seat 21 and its bottom end is rotatably disposed on the pressure plate 26. It should be noted that the elastic element 25 is a spring, which can provide a stable elastic force, so that the auxiliary conveying wheel 23 can fit tightly against the prestressed steel bar, ensuring stability during the conveying process. By rotating the adjusting screw 27, the position of the pressure plate 26 can be adjusted, thereby adjusting the distance between the auxiliary conveying wheel 23 and the main conveying wheel 22 to accommodate prestressed steel bars of different diameters. In addition, the pressure applied by the auxiliary conveying wheel 23 to the steel bar can be adjusted to avoid slippage during conveying.

[0020] In one embodiment of this utility model, such as Figure 1 As shown, the straightening assembly 3 includes a straightening seat 31, an adjusting screw 32, multiple upper straightening wheels 33, a lifting seat 34, and multiple lower straightening wheels 35. The multiple lower straightening wheels 35 are equidistantly rotatably mounted on the straightening seat 31, and the multiple upper straightening wheels 33 are equidistantly rotatably mounted on the lifting seat 34, and are arranged alternately with the lower straightening wheels 35. It should be noted that the straightening seat 31 is fixedly installed on the frame 1. The lower straightening wheel 35 and the upper straightening wheel 33 are both rotatably set by bearings, and the wheel surfaces of the lower straightening wheel 35 and the upper straightening wheel 33 are both arc-shaped to fit the surface of the prestressed steel bar and ensure the straightening effect. The lifting seat 34 is slidably disposed within the straightening seat 31, and the adjusting screw 32 is threadedly disposed within the straightening seat 31, with its bottom end rotatably disposed on the lifting seat 34; It should be noted that by rotating the adjusting screw 32, the height of the lifting seat 34 can be adjusted, thereby adjusting the distance between the upper straightening wheel 33 and the lower straightening wheel 35 to accommodate prestressed steel bars of different diameters. At the same time, the magnitude of the straightening force can be adjusted to ensure the straightening effect. Understandably, when the prestressed steel bar is conveyed between the upper straightening roller 33 and the lower straightening roller 35, the upper straightening roller 33 and the lower straightening roller 35 apply pressure to the steel bar, causing it to deform, thereby eliminating the bending deformation of the steel bar during the production process and achieving the purpose of straightening.

[0021] In one embodiment of this utility model, such as Figure 3 As shown, the clamping assembly 4 includes a clamping cylinder 41, a clamping plate 42, two side plates 43, a mounting ring 44, and a guide sleeve 45. The two side plates 43 are symmetrically arranged on the mounting ring 44. The clamping cylinder 41 is arranged on the side plate 43 and its cylinder shaft end is connected to the clamping plate 42. The mounting ring 44 is arranged on the guide sleeve 45 and communicates with the guide sleeve 45. It should be noted that the mounting ring 44 is fixedly connected to the guide sleeve 45, the guide sleeve 45 is rotatably connected to the inside of the support base 7 through the bearing, and the side plate 43 is fixedly connected to one side of the mounting ring 44 by bolts, thereby limiting the position of the clamping cylinder 41. Two clamping plates 42 are provided and symmetrically located on both sides of the steel bar. The clamping plates 42 are V-shaped to accommodate steel bars of different diameters. A guide rod is provided on the clamping plate 42. The guide rod is slidably connected to a pre-set hole on the side plate 43, thereby guiding and limiting the clamping plate 42. Understandably, when the prestressed steel bar is straightened for the first time, one end extends into the inside of the guide sleeve 45, and the other end is located in a set of conveying components 2. At this time, the clamping cylinder 41 is activated, and the clamping cylinder 41 pushes the clamping plate 42. The two clamping plates 42 clamp and fix the steel bar. When the guide sleeve 45 rotates, the steel bar can be rotated.

[0022] In one embodiment of this utility model, such as Figure 4 As shown, the drive assembly 5 includes a drive motor 51, a gear ring 52, and a gear 53. The gear 53 is mounted on the output shaft of the drive motor 51 and meshes with the outer wall of the gear ring 52. It should be noted that the toothed ring 52 is fixedly connected to the outer wall of the guide sleeve 45 to realize the rotational drive of the clamping assembly 4; Specifically, the drive motor 51 drives the gear 53 to rotate, the gear 53 drives the gear ring 52 through its teeth, and the gear ring 52 drives the guide sleeve 45 to rotate. Under the synchronous action of the side plate 43, the clamping plate 42, the clamping cylinder 41 and other structures, the steel rod follows the guide sleeve 45 to rotate, thereby adjusting the axial angle of the guide sleeve 45. The drive motor 51 is a servo motor, which allows the rotation angle of the steel bar to be adjusted arbitrarily according to usage requirements.

[0023] It should be noted that a PLC controller (not shown in the figure) is installed on the frame 1. The signal terminals of the clamping cylinder 41, the drive motor 51 and the conveyor motor 6 are all connected to the PLC controller, so that the working status and working logic sequence of the clamping cylinder 41, the drive motor 51 and the conveyor motor 6 can be controlled.

[0024] In summary, the straightening device for prestressed steel bar production according to this utility model embodiment conveys the prestressed steel bars through a conveying assembly, allowing the steel bars to enter the straightening assembly. At this point, pressure is applied to the steel bars by the upper and lower straightening rollers, causing deformation and eliminating bending deformation that occurs during production. When the prestressed steel bar detaches from the straightening assembly, one end extends into the guide sleeve, while the other end is located within a set of conveying components. Then, a clamping cylinder is activated, pushing the clamping plates to clamp and fix the steel bar. The guide sleeve is then driven by a driving assembly, enabling the rotation of the steel bar. After the steel bar reaches its rotation position, the clamping assembly releases it, and the conveying motor reverses. The straightening assembly then straightens the rotated steel bar, improving straightening efficiency and ensuring straightening accuracy without requiring manual operation.
