Description

Technical Field

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

[0002] As an indispensable tool in the construction industry, the main function of the steel bar straightening device is to restore the bent and deformed steel bars to an ideal straight state, thereby ensuring its accuracy and reliability in engineering construction. With the rapid development of modern construction technology and the continuous expansion of engineering scale, more stringent and diverse requirements have been put forward for the performance and efficiency of steel bar straightening devices.

[0003] At present, the traditional steel bar straightening device mainly relies on the mechanical stretching principle to work. In actual operation, the user needs to use the traction mechanism to smoothly guide the steel bar into the bearing mechanism, and use a special clamp to firmly clamp one end of the steel bar. Subsequently, the driving mechanism is started to drive the clamp to move to realize the straightening process of the steel bar. However, this traditional device has many shortcomings in the application process. First, the complexity of its structural design increases the difficulty of manufacturing and maintenance. Once a part in the device is damaged, it is often difficult to replace it quickly due to the complexity of its structure, which not only affects the normal use of the device, but also may have an adverse effect on the progress of the project. Secondly, the operation steps of the traditional device are relatively cumbersome, requiring users to have certain operating experience and skills to ensure the smooth progress of the straightening process. However, this increases the complexity of the operation to a certain extent and reduces work efficiency. In addition, the traditional steel bar straightening device has unstable problems in straightening effect. Factors such as improper tensile strength control and unstable clamping of the clamp may lead to poor straightening effect and even cause the risk of steel bar damage. More importantly, different engineering projects have different requirements for steel bar diameters, and traditional devices have limitations in adapting to steel bars of different diameters. In order to meet this demand, users often need to frequently replace fixtures or adjust equipment, which not only increases the complexity of operation, but also reduces work efficiency and may even affect the progress and quality of the project.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Example:

[0024] See also Figure 1 , Figure 2 , Figure 3A steel bar straightening device includes a loading base 1 and two sliding members 3 bolted to the surface of the loading base 1 and three supporting feet 6 welded at equal intervals at the bottom, wherein the sliding member 3 includes two sliding rods 31 and two sliding blocks 32.

[0025] Among them, the loading base 1 serves as the core support of the entire steel bar straightening device, and its design fully considers stability and load-bearing capacity; it is solid and stable, and can effectively bear the weight of other components to ensure that the entire device remains stable during operation; the loading base 1 not only provides solid support for the device, but also lays a solid foundation for the smooth progress of the steel bar straightening work.

[0026] Among them, the design of the sliding member 3 is an indispensable part of the steel bar straightening device, which ensures the smooth movement of the clamping mechanism 5 during the straightening process; the two sliding rods 31 are firmly fixed to the two sides of the surface of the object-carrying base 1 by bolts respectively, and these sliding rods 31 are made of high-strength materials and can withstand large tension and pressure to ensure that they are not easily deformed or damaged during long-term use; next, the two sliding blocks 32 are slidably installed on the two sliding rods 31 respectively, and the sliding blocks 32 are provided with sliding rails matching the sliding rods 31 inside, so that the sliding blocks 32 can slide smoothly on the sliding rods 31. At the same time, the surface of the sliding block 32 is connected to the bottom of the wing plate 51 by bolts. This connection method is both firm and easy to disassemble, which is convenient for maintenance and replacement of parts of the device; in actual application, when the pulling mechanism 2 drives the clamping mechanism 5 to move, the sliding block 32 will slide along the sliding rod 31, driving the clamping mechanism 5 to move smoothly, making the entire straightening process smoother and more efficient.

[0027] The design of the support feet 6 takes into full consideration the unevenness of the ground and the load-bearing requirements of the device; they are made of high-strength materials and have excellent load-bearing capacity and stability. The bottom of the support feet 6 is usually equipped with anti-skid pads or anti-skid patterns to ensure that the device can stand firmly on various ground surfaces and is not easy to slide or tip over; the three support feet 6 can ensure that the device can evenly distribute the pressure when it is stressed, avoiding deformation or damage to the device due to excessive stress on a single point. At the same time, their evenly spaced layout also makes the device more stable and less likely to shake or tilt.

[0028] See also Figure 1 , Figure 3 , Figure 4 , Figure 5A steel bar straightening device comprises a pulling mechanism 2 arranged inside one end of a loading base 1, a positioning mechanism 4 welded on the surface of the other end, a clamping mechanism 5 is arranged on one end of the surface of the pulling mechanism 2, and the pulling mechanism 2 comprises a moving plate 21, a rack 22, a gear 23, a driving motor 24 and a pressing block 25; the positioning mechanism 4 comprises two bearings 41, a driving roller 42, a servo motor 43, two supporting frames 44, a top plate 45 and a movable part 46; the movable part 46 comprises an electric telescopic cylinder 461, an inverted U-shaped plate 462 and a pressing roller 463; the clamping mechanism 5 comprises a wing plate 51, a clamping hole 52, a plurality of anti-slip rings 53, a reinforcement frame 54, two nuts 55, a threaded rod 56, a rotating handle 57 and a rubber block 58.

[0029] Among them, the pulling mechanism 2 is the core power component of the steel bar straightening device. Its structural design and function realization are crucial to the performance of the entire device. Its various parts work together to achieve efficient straightening of the steel bars; the moving plate 21 is the main load-bearing component of the pulling mechanism, and a rack 22 is provided at its bottom, and the side wall is tightly fitted with the inner wall of the loading base 1 to ensure stability and accuracy during the movement; the rack 22 is meshed with the outer wall of the gear 23, and the two ends of the gear 23 are equipped with connecting columns and embedded in one end of the inside of the loading base 1. This design enables the gear 23 to rotate stably inside the loading base 1 while maintaining a good meshing state with the rack 22; the driving motor 24 is the power source of the pulling mechanism 2, and is fixed to the loading base 1 by bolts. At one end of the outer wall of the seat 1, its output end passes through the outer wall of the loading base 1 and is fixedly connected to the connecting column of the gear 23. When the driving motor 24 is started, the gear 23 is driven to rotate through the connecting column, and then the rack 22 and the movable plate 21 are driven to move along the inner wall of the loading base 1. This design makes the power transmission of the pulling mechanism 2 more direct and efficient, and improves the speed and stability of straightening the steel bars; the pressure block 25 serves as a pressing and holding function for the movable plate 21, and its bottom two sides are fixedly connected to the surface of the loading base 1, and the middle part is tightly fitted with the surface of the movable plate 21. This design not only ensures the stability of the movable plate 21 during movement, but also effectively prevents it from shaking or deflecting during movement, thereby ensuring the meshing of the rack 22 and the gear 23.

[0030] Among them, the positioning mechanism 4, as an important part of the steel bar straightening device, is exquisitely designed and powerful, and plays a key role in ensuring the stability and accuracy of the steel bar straightening process; the two bearings 41 are respectively embedded on both sides of the inner side of the carrier base 1, providing stable support for the rotation of the driving roller 42, and the two ends of the driving roller 42 are respectively fixedly connected to the inner rings of the two bearings 41 to ensure stability and accuracy during the rotation process; the top of the driving roller 42 extends out of the surface of the carrier base 1 and directly contacts the steel bar, and guides the movement and positioning of the steel bar through its rotation, and the surface of the driving roller 42 is provided with a groove, making it more suitable for steel bars; the servo motor 43 serves as the power source of the positioning mechanism 4, and its fixed end is connected to the outer side of the carrier base 1 The other end of the side wall is fixed with bolts to ensure stable installation. The output end of the servo motor 43 passes through the inner ring of the bearing 41 and is fixedly connected to one end of the driving roller 42. By accurately controlling the speed and direction of the servo motor 43, the rotation speed of the driving roller 42 can be accurately adjusted to meet the straightening requirements of steel bars of different specifications; the bottom ends of the two support frames 44 are respectively welded to the two sides of one end of the surface of the loading base 1, providing stable support for the top plate 45; the bottom of the top plate 45 is fixed with the top bolts of the support frame 44 to form a solid frame; the movable part 46 is installed on the top plate 45, and the outer wall of its adjustment end is fitted with the inside of the support frame 44. The position of the movable part 46 can be adjusted as needed to adapt to steel bars of different thicknesses.

[0031] Among them, the exquisite structure and flexible adjustment function of the movable part 46 provide a strong guarantee for the accurate positioning and stable straightening of the steel bars; the electric telescopic cylinder 461 serves as the power source of the movable part 46, and its fixed end is firmly connected to the surface of the top plate 45 by bolts to ensure that it will not loosen or shift during the working process; the output end of the electric telescopic cylinder 461 passes through the surface of the top plate 45 and is fixedly connected to the surface of the inverted U-shaped plate 462. Through the telescopic movement of the electric telescopic cylinder 461, the inverted U-shaped plate 462 can be driven to move up and down, thereby realizing the adjustment of the spacing between the pressure roller 463 and the driving roller 42; the inverted U-shaped plate 4 62 serves as a supporting component of the pressure roller 463, and its two ends are respectively fitted with the inner walls of the two support frames 44, ensuring stability and guidance during the adjustment process. At the same time, the interior of the inverted U-shaped plate 462 is designed with a hinge structure, so that the pressure roller 463 can flexibly swing within a certain range to adapt to steel bars of different diameters and shapes; the pressure roller 463 is a key component of the movable part 46, and its outer wall corresponds to the outer wall of the driving roller 42, which can provide a certain pressure when the steel bar passes through, ensuring that the steel bar can be close to the surface of the driving roller 42 during the straightening process, preventing the steel bar from deviating or shaking during the straightening process.

[0032] Among them, the clamping mechanism 5 is used as the steel bar clamping part, and its design directly determines the clamping effect and straightening quality of the steel bar; the wing plate 51 is used as the main load-bearing component of the clamping mechanism, and its bottom end is welded to one end of the surface of the moving plate 21 to ensure the stability of the structure. The two sides of the inner top are bolted to the two sliding blocks 32 by bolts. This design enables the clamping mechanism 5 to slide smoothly with the movement of the sliding blocks 32, thereby realizing continuous clamping and straightening of the steel bar; the clamping holes 52 are provided on the outer wall of the wing plate 51 for accommodating and clamping the steel bar; in order to enhance the clamping effect, a number of anti-skid rings 53 are provided at equal intervals inside the clamping holes 52, and these anti-skid rings 53 are made of materials with a high friction coefficient, which can effectively increase the friction between the steel bar and the clamping holes 52, and prevent the steel bar from slipping during the straightening process; the guide of the reinforcement frame 54 The insertion enhances the stability of the threaded rod 56; its bottom end is welded to the surface of the wing plate 51 to form a solid supporting structure. The reinforcement frame 54 and the wing plate 51 together constitute the main frame of the clamping mechanism 5, providing a stable foundation for the subsequent clamping and straightening of the steel bars; the two nuts 55 are respectively embedded in the surfaces of the wing plate 51 and the reinforcement frame 54, and form a threaded connection with the outer wall of the threaded rod 56. This design enables the threaded rod 56 to rise and fall in the inner circle of the nut 55 through rotation, thereby achieving precise adjustment of the clamping force; the top end of the threaded rod 56 is fixedly connected to the bottom of the rotating handle 57, and the user can conveniently adjust the height of the threaded rod 56 by rotating the handle 57. The rubber block 58 arranged at the bottom end directly acts on the steel bar, and can provide sufficient clamping force through its soft and elastic characteristics.

[0033] Among them, the movable plate 21, the wing plate 51 and the reinforcement frame 54 adopt an integrally cast design, which not only improves the strength and stability of the clamping mechanism 5, but also simplifies the manufacturing process, reduces maintenance costs, and provides a strong guarantee for the performance improvement and reliable operation of the steel bar straightening device.

[0034] The working principle of the steel bar straightening device is as follows: when in use, the steel bar is inserted into the clamping hole 52 through the positioning mechanism 4, and the user adjusts the threaded rod 56 by turning the handle 57 to make the rubber block 58 descend, thereby achieving the purpose of clamping the steel bar, and then starts the electric telescopic cylinder 461 to drive the inverted U-shaped plate 462 downward to make the pressure roller 463 and the driving roller 42 close to each other. At the same time, the steel bar is initially clamped, and the driving roller 42 starts to rotate under the drive of the servo motor 43. The steel bar gradually moves forward under the guidance of the driving roller 42. In this process, the steel bar is subjected to the force of the rotating driving roller 42, is initially straightened and continues to be conveyed forward. When the steel bar reaches a certain length, the driving roller 42 stops rotating to position the steel bar, and then the driving motor 24 drives the gear 23 to rotate, so that the movable plate 21 slides along the sliding rod 31 under the action of the sliding block 32, which can effectively straighten the steel bar.

[0035] It should be noted that the specific models and specifications of the drive motor 24, the electric telescopic cylinder 461, and the servo motor 43 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principles of the drive motor 24, the electric telescopic cylinder 461, and the servo motor 43 are clear to those skilled in the art and will not be described in detail herein.

[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
