Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate straightening, and particularly relates to a novel steel plate bending and straightening device. Background Art

[0002] A steel plate bending and straightening device is equipment used to straighten bent or deformed steel plates to restore their original shape. Such devices usually combine various technologies such as mechanical, hydraulic or pneumatic to achieve the straightening process of steel plates.

[0003] Traditional processes face significant challenges when dealing with steel plates that require large-angle bending or curving. Usually, it relies on manual work with specific tools or complex equipment, and repeatedly hammers the bent part to reduce its curvature, thereby achieving the preliminary straightening of the steel plate. This process is not only inefficient but also has extremely high requirements for the skills of operators, highlighting the limitations and deficiencies of traditional steel plate straightening equipment when dealing with special steel plates.

[0004] Furthermore, although the combination of upper and lower straightening rollers can straighten the steel plate to a certain extent, this method often ignores the flatness problem of the side edge surfaces of the steel plate. Due to the lack of a direct leveling mechanism for the side edge surfaces, the edges of the straightened steel plate often appear uneven, which not only affects the overall quality of the steel plate but also restricts the accuracy and efficiency of subsequent processing operations, and it is difficult to fully guarantee the quality standards of the final product.

[0005] Therefore, it is very necessary to invent a novel steel plate bending and straightening device. Content of the Utility Model

[0009] Preferably, the straightening platform is fixedly connected to the two support frames respectively. A receiving groove allowing the feeding platform roller to enter is formed on the upper surface of the straightening platform. The depth of the receiving groove is the same as the diameter of the feeding platform roller. The receiving groove is a rectangular groove or a U-shaped groove.

[0010] Preferably, two guiding mechanisms are provided and arranged in parallel. Each guiding mechanism includes a guiding frame, a conveying belt and a conveying motor. The guiding frame is fixedly installed on the inner surface of the support frame. One of the conveying rollers rotatably installed inside the guiding frame is fixedly connected to the output end of the conveying motor fixedly installed outside the guiding frame. The conveying belt is assembled on the two conveying rollers and is used to drive the steel plate to be conveyed forward.

[0011] Preferably, the steel plate can be smoothly transferred from the feeding platform roller into the guiding frame; the guiding frame is used to limit the conveying path of the steel plate.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0025] A novel steel plate bending and straightening device provided by the present utility model includes a preliminary straightening mechanism 1, a straightening platform 2, a support frame 3, a lower straightening roller 4, an upper straightening roller 5, and a side straightening roller 6. The feeding platform roller 14 and the straightening pressing plate 13 of the preliminary straightening mechanism 1 are located above the straightening platform 2. The preliminary straightening mechanism 1 and the straightening platform 2 are installed on the support frame 3, while the lower straightening roller 4, the upper straightening roller 5, and the side straightening roller 6 are rotatably installed on the support frame 3. The lower straightening roller 4 is located below the upper straightening roller 5, and the side straightening roller 6 is located between the lower straightening roller 4 and the upper straightening roller 5.

[0026] Furthermore, the preliminary straightening mechanism 1, as the core part of the present utility model, is exquisitely designed and powerful in function. In the mechanism, the bracket 11 is firmly fixed on the support frame 3, providing a solid support foundation for the entire preliminary straightening process. Above the bracket 11, at least one hydraulic cylinder 12 is firmly installed. The output ends of these hydraulic cylinders 12 are closely connected to the straightening pressing plate 13. Through the telescopic action of the hydraulic cylinders 12, the straightening pressing plate 13 can apply precise pressure on the steel plate to achieve preliminary rapid straightening. At the same time, in order to enhance the flexibility and adaptability during the straightening process, the sliding seat 15 is ingeniously designed to be slidably installed on the support frame 3. The output end of the hydraulic rod 17 is fixedly connected to the sliding seat 15. Through the telescopic movement of the hydraulic rod 17, the sliding seat 15 and its components can smoothly move along the support frame 3, thereby quickly and flexibly conveying the preliminarily straightened steel plate to the next straightening process, ensuring the continuity and high efficiency of the steel plate processing flow.

[0027] Furthermore, between the two sliding seats 15, a number of feeding platform rollers 14 are ingeniously rotatably installed. They not only serve as the conveying medium for the steel plate but also play a role in stabilizing the steel plate during the straightening process. The feeding motor 16 is fixedly connected to one end of the feeding platform roller 14 close to the guiding mechanism 7. Driven by the motor, the feeding platform roller can drive the steel plate to move forward smoothly, making full preparations for the subsequent straightening operation.

[0028] Furthermore, as an important place for straightening the steel plate, the straightening platform 2 is also exquisitely designed. The platform is firmly fixed to the support frame 3, and the receiving groove opened on its upper surface perfectly matches the size of the feeding platform roller 14, ensuring that the roller can smoothly enter and exit. When the steel plate needs to be initially straightened, the feeding platform roller 14 is driven by the hydraulic rod 17 and will drop into the receiving groove of the straightening platform 2, allowing the steel plate to contact the upper surface of the straightening platform 2. Thus, the steel plate is initially straightened by the downward pressing straightening pressing plate 13, improving the stability and straightening performance of the steel plate during the initial straightening. The rectangular or U-shaped design of the receiving groove not only ensures practicality but also takes into account aesthetics.

[0029] Furthermore, in order to ensure that the path of the steel plate is accurate during the straightening process, the guiding mechanism 7 is set to two and is parallel to each other. The guiding frame 71 is fixed inside the support frame 3, and the conveying roller rotating inside is connected to the external conveying motor 73. Driven by the conveying belt 72, the steel plate can smoothly enter the guiding frame 71 and be precisely guided to the next process. The design of the guiding frame 71 not only restricts the conveying path of the steel plate but also improves the stability and reliability of the entire straightening process.

[0030] Furthermore, on the support frame 3, the transmission gearbox 8 is fixedly installed. It is connected to the straightening motor 9, providing strong power support for the entire straightening system. Two sets of linked transmission mechanisms are arranged inside the transmission gearbox. These mechanisms adopt the way of rack transmission or gear transmission to ensure the efficient transmission of power and torque force. The output ends of the transmission gearbox 8 are respectively connected to the lower straightening roller 4 and the upper straightening roller 5. Through the rolling and extrusion of the rollers, further straightening of the steel plate is achieved. The lower straightening roller 4 and the upper straightening roller 5 are arranged in a staggered manner, which not only increases the straightening force but also avoids local overpressure of the steel plate. In addition, the addition of the side straightening roller 6 is the finishing touch. It is located between the two ends of the lower straightening roller 4 and below the upper straightening roller 5, and is arranged perpendicular to the ground, effectively leveling the side edges of the steel plate and improving the overall quality of the product. The lower straightening roller 4 and the upper straightening roller 5 rotate in opposite directions.

[0031] The working principle is as follows: First, when the steel plate to be straightened is fed into this device, it first comes into contact with the feeding platform roller 14 of the preliminary straightening mechanism 1. The steel plate will be located above the straightening platform 2. At this time, the feeding platform roller 14 gradually descends driven by the hydraulic rod 17 until the roller completely enters the receiving groove on the upper surface of the straightening platform 2, making the steel plate in close contact with the straightening platform 2. After the steel plate contacts the straightening platform 2, the hydraulic cylinder 12 starts to work. Its output end pushes the straightening pressing plate 13 downward to apply precise and uniform pressure to the steel plate. Since the telescopic movement of the hydraulic cylinder 12 is controllable and stable, the straightening pressing plate 13 can effectively flatten large-angle bends or curved parts on the steel plate to achieve preliminary rapid straightening. After straightening, the straightening pressing plate 13 rises and resets.

[0032] After the preliminary straightening is completed, the hydraulic rod 17 works again. Its output end pushes the slide seat 15 and the feeding platform roller 14 group upward. So that the preliminarily straightened steel plate can smoothly transition back to the feeding platform roller 14, and the feeding motor 16 is started. The preliminarily straightened steel plate is conveyed forward by the feeding platform roller 14 to the entrance of the guiding mechanism 7. After the steel plate enters the guiding mechanism 7, it comes into contact with the conveying belt 72 in the guiding frame 71. The conveying motor 73 is started to drive the conveying roller to rotate, and the steel plate is smoothly conveyed along the guiding frame 71 driven by the conveying belt 72. The design of the guiding frame 71 ensures that the path of the steel plate during conveying is accurate and improves the stability and reliability of the entire straightening process.

[0033] When the steel plate is guided by the guiding mechanism 7 between the lower straightening roller 4 and the upper straightening roller 5, the straightening motor 9 is started. The power is transmitted to the rollers through the transmission mechanism in the transmission case 8. The lower straightening roller 4 and the upper straightening roller 5 start to roll and squeeze the steel plate under the drive of the power. At the same time, the side straightening roller 6 also starts to work to level the side edge surfaces of the steel plate. Under the combined action of the upper and lower and side straightening rollers 6, the steel plate is comprehensively and precisely straightened and finally output as a high-quality product.

[0034] Using the technical solution described in this utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of this utility model and achieving the above technical effects all fall within the protection scope of this utility model.
