Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, specifically a leveling device for a straightening machine. Background Technology

[0002] During the production process, sheet metal may be deformed due to various reasons, such as twisting, warping, bending, or wavy patterns. These problems can affect the quality and precision of subsequent processing. Therefore, it is necessary to correct the sheet metal using a straightening machine. The leveling equipment of the straightening machine is usually used to correct the shape of metal sheets or workpieces to ensure that their flatness and geometric dimensions meet the requirements. Although the straightening machine achieves the function of limiting the two sides of the sheet metal during inspection, the flatness of the straightened sheet metal cannot be directly inspected.

[0003] Chinese patent discloses a steel plate straightening machine (authorization announcement number CN217990723U). This patented technology includes a steel plate straightening machine body, a frame mounted on one side of the machine body, rollers mounted on the frame for conveying steel plates, clamping plates slidably mounted on the frame perpendicular to the roller axis for calibrating the steel plates, and a drive device mounted on the frame for driving the clamping plates to slide towards or away from the steel plates. This application has the effect of straightening the conveyed steel plates and reducing the deviation of the steel plates during conveying.

[0004] This patented technology avoids steel plate misalignment during the straightening process, but it still has shortcomings in practice. Flatness testing cannot be performed after straightening. Steel plates in shipbuilding require a certain degree of flatness to ensure structural stability and safety. Flatness testing helps ensure the quality and proper connections of hull components. Similarly, for containers such as lockers, barrels, or gas tanks, flatness testing helps ensure the required volume and sealing. Steel plates have a large surface area, requiring additional testing after straightening, which adds extra handling and inspection processes, making it cumbersome and inconvenient. Therefore, those skilled in the art have provided a flattening device for straightening machines to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a leveling device for a straightening machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a leveling device for a straightening machine, including a frame, a mounting frame, a mounting cylinder, a fixing plate, and a mounting frame. The frame has symmetrically distributed mounting frames inside. A motor is installed at one end of each mounting frame, and a straightening roller rotatably mounted inside the mounting frame is installed at the motor's output end. Two hydraulic rods with telescopic ends connected to the mounting frames are installed inside both the upper and lower ends of the frame. A mounting frame is installed inside one end of each mounting frame. A hydraulic rod with a telescopic end connected to the mounting frame is installed inside the upper end of the frame. Equally spaced trigger rods are slidably mounted inside the mounting frame. Displacement sensors corresponding to the trigger rods are installed on the inner wall of the upper end of the mounting frame. A mounting cylinder is installed at the lower end of each trigger rod. A spring sleeved on the outer wall of the trigger rod and connected to the lower end of the mounting frame is installed at the upper end of the mounting cylinder. A ball bearing is rotatably mounted inside the lower end of the mounting cylinder.

[0007] Furthermore, the frame is provided with two sets of equidistant conveying rollers, and there are equidistant support plates between the conveying rollers with their upper ends flush with the conveying rollers.

[0008] Specifically, the conveyor rollers provide rolling support to the bottom of the sheet material, and the gap between the conveyor rollers is compensated by the support plate, thereby providing bottom support to the conveyed sheet material.

[0009] Furthermore, the mounting frame is provided with a second support plate located between the straightening rollers and whose lower end is flush with the lower end of the straightening rollers;

[0010] Specifically, the second support plate compensates for the gap between the straightening rollers to avoid the problem of large-span bending of the plate when the rollers are straightening the plate due to the small contact area with the plate.

[0011] Furthermore, a control cabinet and a high-frequency generator are provided at one end of the frame, and heating tubes located inside the frame and symmetrically distributed are provided at one end of the high-frequency generator;

[0012] Specifically, the controller receives signals from the displacement sensor and controls the electrical equipment, while the heating element is heated by a high-frequency generator to heat the passing plate.

[0013] Furthermore, an alarm is provided at the upper end of the mounting frame;

[0014] Specifically, the alarm will be triggered to alert staff when a non-compliance is found during the process of checking the flatness of the board surface.

[0015] Furthermore, a fixing plate is provided inside the upper end of the mounting bracket, and a mounting plate is installed at the lower end of the fixing plate by bolts. A brush distributed in a rectangular array is provided at the lower end of the mounting plate.

[0016] Specifically, the fixing plate and the mounting plate are fixed with bolts, and the surface of the passing straightening roller is brushed with a brush.

[0017] Furthermore, through holes are provided at the four corners of the upper end of the mounting bracket, and a bracket corresponding to the through holes is provided at the upper end of the mounting bracket. A guide rod is provided at the upper end of the fixing plate, which is slidably inserted into the through holes and the bracket. A compression spring is sleeved on the outer wall of the guide rod, with its upper and lower ends respectively connected to the bracket and the fixing plate.

[0018] Specifically, the fixed plate is elastically supported by springs, which in turn applies elastic force to the brush, squeezing it into contact with the straightening roller.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple sets of straightening rollers roll the conveying plate, and during the rolling process, the uneven parts of the plate are flattened and straightened. After straightening, the upper surface of the plate contacts the ball bearings. Under normal circumstances, the squeezing force applied to the ball bearings acts on the spring, applying a fixed amount of squeezing force to the spring. When an uneven part of the plate contacts the ball bearings, the spring is subjected to a fixed amount of pressure imbalance. The displacement sensor detects the displacement of the trigger rod and alarms the terminal, thereby realizing the detection of the flatness of the straightened plate and avoiding the subsequent plate transfer and inspection process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] Example 1:

[0029] A leveling device for a straightening machine includes a frame 1, a mounting frame 4, a mounting cylinder 6, a fixing plate 13, and a mounting frame 9. The frame 1 has symmetrically distributed mounting frames 4 inside. One end of the mounting frame 4 is equipped with a motor 5. The output end of the motor 5 is equipped with a straightening roller 10 that is rotatably installed inside the mounting frame 4. Both the upper and lower ends of the frame 1 are equipped with hydraulic rods 20 whose telescopic ends are connected to the mounting frames 4. One end of the mounting frame 4 is equipped with a mounting frame 9. The upper end of the frame 1 is equipped with a hydraulic rod 8 whose telescopic end is connected to the mounting frame 9. The mounting frame 9 has equidistantly distributed trigger rods 24 that are slidably installed inside. The upper inner wall of the mounting frame 9 is equipped with displacement sensors 22 corresponding to the trigger rods 24. The lower end of the trigger rods 24 is equipped with a mounting cylinder 6. The upper end of the mounting cylinder 6 is equipped with a spring 25 that is sleeved on the outer wall of the trigger rods 24 and whose upper end is connected to the lower end of the mounting frame 9. The lower end of the mounting cylinder 6 is rotatably equipped with ball bearings 26.

[0030] The frame 1 is equipped with two sets of equidistant conveyor rollers 2, and there are equidistant support plates 7 between the conveyor rollers 2 with their upper ends flush with the conveyor rollers 2.

[0031] The mounting frame 4 is equipped with a support plate 21 located between the straightening rollers 10 and with its lower end flush with the lower end of the straightening rollers 10;

[0032] A control cabinet 11 and a high-frequency generator 12 are installed at one end of the rack 1;

[0033] An alarm 23 is installed at the upper end of the mounting frame 9;

[0034] In this embodiment, by integrating flatness detection into the straightening process, the additional transfer and inspection procedures caused by the inability to perform flatness detection after straightening are avoided. This integrated design simplifies the operation process and improves efficiency. The hydraulic system is equipped with a displacement sensor 22 and an alarm system. During the transfer of the sheet metal, once a straightening problem or abnormality is detected, the alarm 23 can be quickly triggered to promptly notify the staff to perform secondary straightening or maintenance. This rapid feedback helps to reduce the risk of possible production accidents and improve operational efficiency, thereby avoiding the need to transfer the straightened sheet metal and perform flatness detection.

[0035] Example 2:

[0036] One end of the high-frequency generator 12 is provided with heating tubes 3 located inside the frame 1 and symmetrically distributed;

[0037] The upper end of the mounting bracket 4 is provided with a fixing plate 13, and the lower end of the fixing plate 13 is provided with a mounting plate 14 by bolts. The lower end of the mounting plate 14 is provided with brushes 15 arranged in a rectangular array.

[0038] Through holes 16 are provided at the four corners of the upper end of the mounting bracket 4. A bracket 17 corresponding to the through hole 16 is provided at the upper end of the mounting bracket 4. A guide rod 19 is provided at the upper end of the fixing plate 13, which is slidably inserted into the through hole 16 and the bracket 17. A compression spring 18 is sleeved on the outer wall of the guide rod 19, which is connected to the bracket 17 and the fixing plate 13 at its upper and lower ends respectively.

[0039] In this embodiment, the introduction of the brush 15 cleaning mechanism can help remove rust and foreign matter adhering to the surface of the plate due to the roller pressing and straightening of the plate by the straightening roller 10, keeping the surface of the straightening roller 10 clean and facilitating the subsequent plate straightening stability. The replaceable mounting plate 14 makes it more convenient to replace and maintain the brush 15 during use. The high-frequency heating method heats and softens the steel plate by conducting electromagnetic energy, effectively improving the efficiency of the straightening process.

[0040] Working principle: The control cabinet 11 controls the operation of the electrical equipment. When the motor 5 is running, it drives the straightening roller 10 to rotate inside the mounting frame 4. According to the rear end of the plate, the mounting frame 4 located at the upper end of the frame 1 moves longitudinally through the hydraulic rod 20 to adjust the spacing of the relatively distributed straightening rollers 10. The upper straightening roller 10 and the lower straightening roller 10 rotate away from each other. The conveying roller 2 provides rolling support for the bottom of the plate. When the plate enters the straightening roller 10, the straightening roller 10 squeezes the plate. The curved parts of the plate are straightened by roller pressure. When the straightening roller 10 rotates, it is brushed by the brush 15. Rust and foreign objects on the plate are brushed off after adhering to the straightening roller 10. The brush 15 is gradually worn during use. The elastic support force of the compression spring 18 acts on the fixing plate 13, so that the brush 15 comes into contact with the surface of the straightening roller 10. The mounting plate 14 and the fixing plate 13 are installed by bolts, which makes it easy to replace the brush 15.

[0041] During the conveying of the straightening plate, the high-frequency generator 12 is an electronic device that can convert electrical energy into a high-frequency electromagnetic field. The high-frequency current generated by the high-frequency generator 12 is transmitted to the heating coil, i.e., the heating tube 3, through inductive coupling. When the high-frequency current passes through the heating tube 3, a strong alternating magnetic field is generated, which allows the heating tube 3 itself and the energy conducted within it to be transferred to the steel plate near the heating tube 3 through inductive coupling. Usually, the heating temperature of the steel plate is controlled at around 500℃ to 900℃, which is a common range. This temperature range is conducive to the softening treatment of the steel, making it easier to perform roll forming. After the plate is heated and softened, the straightening roller 10 can better perform the straightening process of the plate during the roll forming process.

[0042] Hydraulic rod 8 operates, driving mounting frame 9 to descend. Ball bearing 26 is adjusted to the appropriate height for steel plate detection. When the plate passes through ball bearing 26, it applies pressure to ball bearing 26, which in turn applies pressure to spring 25, pushing trigger rod 24 to move. By adjusting the trigger condition of displacement sensor 22 through the terminal, if the travel range of trigger rod 24 exceeds the set value, displacement sensor 22 transmits a signal to control box, which in turn controls alarm 23 to emit an alarm audio, reminding staff to perform secondary correction of the plate or to check whether the straightening roller 10 is damaged, so as to stop the loss in time.
