Description

[0001] The utility model relates to the technical field of aluminum plate and strip production, in particular to a deflection roller device used for adjusting the shape of an aluminum plate and strip. Background Art

[0002] In the finished product production process of aluminum strip, the strip bending needs to be controlled by a bending and straightening machine to obtain a high-quality plate shape. For the bending and straightening equipment that adopts the two-bending and two-straightening bending and straightening mode, a deflection roller is equipped at the straightening machine outlet to adjust the curvature of the large plate. The deflection roller adopts a single motor and turbine elevator structure for height adjustment. A rotary encoder is equipped on one side. The roller seat displacement structure adopts a copper slide plate. The frame is installed as a whole. In theory, the deflection roller can adjust the overall bending of the aluminum strip by lifting and lowering a single motor. In the actual production process, due to the uneven distribution of rolling stress of aluminum strip, the incoming plate shape is generally loose on one side or tight on one side. At this time, the deflection roller cannot be lifted and lowered as a whole to control the bending of the large plate on both sides. In the above situation, the operator needs to stop the machine and test the production by disassembling and assembling the transmission coupling between the turbine elevators on both sides several times to confirm the plate shape. The adjustment process is quite time-consuming and laborious. Furthermore, when the tension fluctuates when the machine speed increases or decreases, the large clearance between the worm gear elevator and the roller seat will also affect the stability of the strip shape.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0019] like Figure 1-3 As shown, this embodiment provides a deflector roller device for adjusting the shape of an aluminum plate strip, comprising a frame 1, a deflector roller 2 and two adjustment mechanisms arranged on the left and right sides of the deflector roller 2; the adjustment mechanism comprises a reduction motor 7, a worm gear lift 8, a bearing seat 3, a linear guide slider 4, a lifting cylinder 5 and a displacement sensor 6, the reduction motor 7 and the worm gear lift 8 are both installed on the frame 1, the reduction motor 7 is connected to the bearing seat 3 through the worm gear lift 8 to drive it to move up and down, the linear guide slider 4 comprises a guide rail 401 and a slider 402 that slides therewith, the guide rail 401 is vertically installed on the frame 1, the bearing seat 3 is fixedly connected to the slider 402, the piston rod of the lifting cylinder 5 is connected to the bearing seat 3, and the displacement sensor 6 is arranged beside the bearing seat 3 to detect the displacement of the bearing seat; the deflector roller 2 is horizontally arranged and its left and right ends are rotatably connected to the bearing seats 3 of the two adjustment mechanisms respectively.

[0020] Specifically, the reduction motor 7 is installed on the motor base 9, the motor base 9 is fixedly connected to the frame 1, the worm gear lift 8 is installed on the frame 1, the output end of the reduction motor 7 is transmission connected to the input end of the worm gear lift 8 (which can be achieved through a coupling 10), and the output end of the worm gear lift 8 is rotationally connected downward to the bearing seat 3 to drive the bearing seat 3 to move upward or downward.

[0021] In this device, the bearing seats on both sides of the deflector roller are raised and lowered by a double-reduction motor and a worm gear lift. The curvature of the large plate can be adjusted online according to the shape of the incoming material through a single-sided motor lifting method. The entire process does not require shutdown or disassembly of the device for processing, which effectively improves the convenience, accuracy and adjustable range of the deflector roller height and aluminum strip shape adjustment.

[0022] In addition to using adjustment mechanisms on both sides of the deflector roller to adjust the bearing seat, this device also provides linear guide sliders to limit the up and down movement of the bearing seat, thereby ensuring the accuracy of the up and down movement. In addition, two lifting cylinders are added on both sides of the deflector roller, and upward pressure is applied to the bearing seat by the lifting cylinders, thereby effectively eliminating the screw gap of the worm gear lift and the possible connection gap between the worm gear lift and the bearing seat. The cylinder lifting force is set to be greater than the deadweight of the deflector roller and the bearing seat. In this embodiment, a pressure relief valve is also provided on the air supply pipeline of the lifting cylinder to avoid pipe bursting due to high pipeline pressure.

[0023] In this embodiment, the bearing seat 3 is a split bearing seat, so that the bearing seat can be disassembled and the deflector roller 2 can be taken out. The frame 1 includes a left frame 101, a right frame 102 and a plurality of crossbeams 103. The left frame 101 and the right frame 102 are respectively used to install two adjustment mechanisms on the left and right sides. The left frame 101 and the right frame 102 are fixedly connected to form a frame as a whole through the crossbeams 103. In addition, a groove for taking out the deflector roller can be provided on the side of the left and right frames close to the deflector roller. In this embodiment, the frame 1 includes four crossbeams 103, namely, the front upper, the front lower, the rear upper and the rear lower. The left and right ends of the four crossbeams are respectively fixedly connected to the left and right frames by bolts. Through the above design, a roller replacement space for taking out the deflector roller is formed at the outlet position on the rear side of the deflector roller. Each time the roller is changed, it is only necessary to remove the single crossbeam above the outlet and the bearing seat pressure covers on both sides, which saves time and effort.

[0024] The displacement sensor is installed on the frame and its detection part is linked with the bearing seat to detect the up and down displacement of the bearing seat and improve the accuracy of the height adjustment of the deflector roller. At the same time, by comparing the detection data of the two displacement sensors, the height difference of the bearing seats on both sides can be obtained. By setting certain early warning measures, the risk of the bearings being stuck due to the large height difference of the bearing seats on both sides can be avoided.

[0025] When the device is working, the height of the deflector roller 2 is adjusted by two reduction motors 7 and worm gear lifters 8 on the left and right sides of the deflector roller 2 according to the need to adjust the shape of the aluminum strip. The pressure of the lifting cylinder 5 is set to 0.4Mpa to eliminate the screw gap of the worm gear lifter 8. A pressure relief valve is installed on the air supply pipeline to automatically release the pressure when the pressure exceeds 0.6Mpa to avoid the burst of the air supply pipeline caused by excessive pressure. When replacing the deflector roller, only the upper gland of the split bearing seat 3 and the crossbeam 103 on the frame 1 need to be removed, and the deflector roller can be removed from the outlet side for quick replacement. The height of the bearing seat 3 is measured by the displacement sensors 6 on both sides to realize the height monitoring of the bearing seats 3 on both sides, improve the adjustment accuracy of the deflector roller, and avoid the bearing being stuck due to excessive unilateral swing. The operator can adjust the deflector roller pressure in the hollow system in real time according to the actual shape of the strip, and obtain the real-time height at the same time, avoiding the loss of production efficiency caused by stopping the machine to adjust the shape.

[0026] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
