Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a limiting device for a four-roll corrugated plate rolling machine. Background Technology
[0002] In the production of corrugated sheets, precise positioning is crucial for ensuring the quality of the corrugated sheets and improving production efficiency when a four-roller corrugated sheet rolling machine rolls the sheets. However, traditional positioning methods have significant drawbacks, limiting processing accuracy and production efficiency. Firstly, the positioning accuracy is insufficient. Traditional methods rely on manual adjustment of the positioning structure, making it difficult to accurately control the lateral and longitudinal positions of the sheet during the rolling process. During high-speed rolling, the sheet is prone to lateral movement due to uneven roller friction and stress release, leading to deviations in corrugation spacing and corrugation distortion. This fails to meet the high-precision requirements of corrugated sheets in building decoration and soundproofing pipes, increasing subsequent calibration costs. Secondly, specification switching is cumbersome. When rolling corrugated sheets of different widths and corrugation parameters, manual replacement or adjustment of the positioning components is required, resulting in significant capacity loss in multi-variety, small-batch production scenarios. Furthermore, manual adjustment has low precision, easily leading to batch scrap.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Traditional rigid limiting devices are in direct contact with the sheet material. When rolling thin corrugated sheets, the contact stress concentration can easily cause deformation and scratches on the edge of the sheet material, affecting the appearance and mechanical properties of the product and increasing the cost of subsequent grinding and repair. Utility Model Content

[0007] Preferably, the surface of the limiting plate is provided with an installation groove, and a plurality of rollers are fixedly connected to the inner wall of the installation groove of the limiting plate.

A fixing rod is fixedly connected to the inner wall of the installation hole, and a conveying cylinder is rotatably connected to the arc surface of the fixing rod.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0020] Reference Figures 1-4 As shown, this utility model provides a technical solution: a limiting device for a four-roll corrugated plate rolling machine, including a plate rolling machine body 1, a connecting plate 2 fixedly connected to the surface of the plate rolling machine body 1, two fixing plates 3 fixedly connected to the surface of the connecting plate 2, a servo motor 4 fixedly connected to one side of the fixing plate 3, a lead screw 5 fixedly connected to the output end of the servo motor 4, a threaded cylinder 6 threadedly connected to the arc surface of the lead screw 5, and a limiting plate 7 fixedly connected to one end of the threaded cylinder 6. An automated limiting system is constructed through the plate rolling machine body 1, connecting plate 2, fixing plate 3, servo motor 4, lead screw 5, threaded cylinder 6, and limiting plate 7: the servo motor 4 drives the lead screw 5 to rotate, driving the threaded cylinder 6 and limiting plate 7 to move, achieving precise limiting of the plate material and rapid adaptation for rolling corrugated plates of different specifications. Two semi-circular plates 8 are fixedly connected to the surface of the fixing plate 3, and a limiting rod 9 is slidably inserted into the semi-circular plate 8. One end of the limiting rod 9 is fixedly connected to the limiting plate 7, and the limiting rod 9 slides within the semi-circular plate 8, ensuring precise positioning only along the axial direction of the lead screw 5. The lateral positioning accuracy of the corrugated plate is improved by moving the plate 7. The surface of the positioning plate 7 has a mounting groove, and several rollers 10 are fixedly connected to the inner wall of the mounting groove. The rolling of the rollers 10 reduces the feeding resistance of the plate. An auxiliary plate 16 is fixedly connected to one side of the connecting plate 2. The surface of the auxiliary plate 16 has a mounting hole 11, and the inner wall of the mounting hole 11 is fixedly connected to a fixing rod 12. The arc surface of the fixing rod 12 is rotatably connected to a conveyor cylinder 13. The conveyor cylinder 13 can dynamically adjust the tension of the plate to prevent the corrugated plate from wrinkling and breaking due to uneven tension. A friction pad 15 is fixedly connected to the surface of the connecting plate 2. The surface of the friction pad 15 has an anti-slip texture. The flexible friction pad 15 avoids direct metal contact and reduces the indentation rate on the plate surface. An elastic protective pad 14 is fixedly connected to the surface of the connecting plate 2. The elastic protective pad 14 can absorb the impact energy during the rolling process, reduce equipment vibration, and extend the life of the rollers and bearings. The auxiliary plate 16 is tilted, and the tilt angle allows the auxiliary plate 16 to provide a gradual guide to the plate.
[0021] Working Principle: When the plate rolling machine body 1 is running, the servo motor 4 drives the lead screw 5 to rotate as a power source. Utilizing the threaded transmission between the lead screw 5 and the threaded cylinder 6, the rotational motion of the motor is converted into the linear motion of the limiting plate 7, achieving precise control of the position of the limiting plate 7. The limiting plate 7 moves axially along the lead screw 5, quickly adapting to the rolling limit of different specifications of plates according to the requirements of the corrugated plate width and corrugation parameters. This corrects the lateral movement of the plate and solves the problem of insufficient precision in manual limiting. During the movement of the limiting plate 7, the semi-circular plate 8 cooperates with the limiting rod 9 to restrict the radial sway of the limiting plate 7, ensuring that it only precisely displaces along the axial direction of the lead screw 5. This further enhances the lateral limiting accuracy of the corrugated plate, disperses the lateral force during the rolling process, and prevents damage to the lead screw 5 and threaded cylinder 6 due to radial force, reducing the equipment failure rate. For corrugated plates being rolled, the surface of the limiting plate 7 is mounted with... The rollers 10 inside the groove make rolling contact with the sheet material, transforming traditional sliding friction into rolling friction, significantly reducing the feeding resistance of the sheet material, while also reducing edge deformation and scratches on thin sheet materials, thus lowering later repair costs. The auxiliary plate 16 on one side of the rolling machine cooperates with the conveyor cylinder 13 through the fixed rod 12 to provide progressive guidance and pre-correction for the sheet material. The conveyor cylinder 13 dynamically adjusts the tension of the sheet material to prevent wrinkling and breakage of the corrugated sheet due to uneven tension; it also reduces the initial contact stress between the roller and the sheet material, avoiding edge cracking during the rolling of thin sheet materials. In addition, the friction pads 15 on the surface of the connecting plate 2 utilize flexible contact to enhance the longitudinal positioning of the sheet material, while avoiding surface indentations caused by metal contact. The elastic protective pads 14 absorb the impact energy of rolling, reduce equipment vibration, extend the life of rollers and bearings, adapt to stress fluctuations during the rolling of thick plates, and control the corrugated plate wave height deviation.
[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
