Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a rolling linear control device. Background Technology

[0002] In the field of metal processing, rolling is a crucial forming method. Its purpose is to apply pressure to metal billets using rolls, causing plastic deformation to obtain metal sheets or strips with specific dimensions, shapes, and properties. With continuous industrial development and increasingly stringent quality requirements for metal materials across various sectors, precise control of the rolling process has become a key objective pursued by the industry.

[0003] Traditional rolling equipment has revealed numerous problems in practical applications. In terms of thickness control, some equipment relies on relatively simple mechanical adjustment structures, making it difficult to make precise and rapid adjustments to the roll gap according to different rolling requirements. This results in large thickness deviations in the rolled metal products, failing to meet the high precision requirements of sheet metal thickness in industries such as electronic equipment manufacturing. Consequently, this leads to high scrap rates, resource waste, and increased costs.

[0004] In terms of plate shape control, existing equipment lacks effective pre-shaping methods. If the plate shape is not fully optimized before rolling, defects such as wavy or warped shapes are prone to occur after rolling, affecting the product appearance and subsequent processing. In industries such as automobile manufacturing, this can cause difficulties in parts assembly, reduce production efficiency and quality, and when adapting to plates of different widths, traditional equipment has poor flexibility. The roll adjustment mechanism is difficult to adjust quickly and accurately according to the width of the plate, which limits the processing capability for diversified products, reduces versatility and production efficiency, and increases the equipment purchase cost for enterprises. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this utility model provides a rolling linear control device.

[0006] A linear rolling control device includes a base, support seats, hydraulic cylinders, connecting frames, a first motor, an upper roll, a second motor, a lower roll, connecting plates, movable frames, an adjustment assembly, and a plate shape control assembly. The base has symmetrically connected support seats on its top. Hydraulic cylinders are mounted on the upper sides of each support seat. Connecting frames are connected to the telescopic rods of the hydraulic cylinders, and first motors are mounted on each connecting frame. An upper roll is movably connected between the upper sides of the two support seats. The front and rear ends of the upper roll are connected to the corresponding output shafts of the first motors. A second motor is mounted on the lower side of each support seat. The two second motors penetrate the inner side of the base, and a lower roll is connected between the two output shafts. Connecting plates are connected to the front and rear ends of the lower roll. Movable frames are slidably connected to the inner sides of the connecting plates, and the movable frames are located outside the lower rolls. An adjustment assembly is provided on the base, and a plate shape control assembly is provided on the support seats.

[0007] Furthermore, it is particularly preferred that both the upper and lower rolls are made of alloy tool steel and have undergone quenching and chrome plating treatment.

[0008] In addition, it is particularly preferred that the bottom of the base is provided with a shock-absorbing rubber pad, which is bonded and fixed to the base with strong adhesive.

[0009] Furthermore, it is particularly preferred that the adjustment assembly includes a sliding frame, a third motor, and a first screw. The third motor is installed in the middle of the top of the base. The third motor is a dual-axis motor, and the first screw is connected to its front and rear output shafts respectively. The sliding frame is rotatably connected to the movable frame, and the sliding frame is threadedly connected to the corresponding first screw.

[0010] Furthermore, it is particularly preferred that the plate shape control assembly includes a fourth motor, a second screw, a fixed frame, and a connecting roller. The fourth motor is symmetrically mounted on the left side of the support base. The output shaft of the fourth motor is connected to the second screw, and the fixed frame is slidably connected to the second screw.

[0012] Compared with the prior art, the present invention has the following advantages: 1. By controlling the lifting and lowering of the upper roll with a hydraulic cylinder, the distance between the upper and lower rolls can be precisely adjusted to meet the rolling requirements of metals of different thicknesses, ensure the thickness accuracy of the rolled products, and effectively reduce thickness deviation.

[0013] 2. In the plate shape control component, the fourth motor drives the second screw, which in turn drives the fixed frame and connecting rollers to adjust the spacing, performing initial rolling and shaping of the workpiece, improving the straightness and flatness of the workpiece, optimizing the plate shape, and improving product quality.

[0014] 3. Inside the adjustment assembly, the third motor drives the first screw, causing the movable frame to slide along the connecting plate. The spacing can be flexibly adjusted according to the width of the rolled piece, and the front and rear sides of the rolled piece are limited to ensure that the rolled piece is centered and parallel during rolling. It is suitable for rolling metals of various width specifications, improving the versatility of the device.

[0015] 4.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] Example: A rolling linear control device, such as Figures 1-4 As shown, the assembly includes a base 1, support seats 2, hydraulic cylinders 3, connecting frames 4, a first motor 5, an upper roller 6, a second motor 7, a lower roller 8, a connecting plate 9, a movable frame 10, an adjustment assembly, and a plate shape control assembly. Support seats 2 are symmetrically welded to the top of the base 1. Hydraulic cylinders 3 are bolted to the upper side of each support seat 2. Connecting frames 4 are connected to the telescopic rods of the hydraulic cylinders 3. First motors 5 are bolted to the connecting frames 4. Upper rollers 6 are movably connected between the upper sides of the two support seats 2. The front and rear ends of the upper rollers 6 are connected to the output shafts of the corresponding first motors 5. A second motor 7 is mounted on the lower side of each support seat 2. The motor 7 and two second motors 7 pass through the inner side of the base 1, and the lower roller 8 is connected between the two output shafts. The upper roller 6 and the lower roller 8 are both made of alloy tool steel and the surface is quenched and chrome-plated to improve the wear resistance and corrosion resistance of the rollers. The front and rear ends of the lower roller 8 are respectively connected to the connecting plate 9. The movable frame 10 is slidably connected to the inner side of the connecting plate 9. The movable frame 10 is located outside the lower roller 8. The base 1 is equipped with an adjustment component, and the support seat 2 is equipped with a plate shape control component. The bottom of the base 1 is equipped with a shock-absorbing rubber pad, which is bonded to the base 1 with strong adhesive to reduce the vibration generated during the operation of the device.

[0023] like Figure 3As shown, the adjustment assembly includes a sliding frame 11, a third motor 12, and a first screw 13. The third motor 12 is bolted to the top center of the base 1. The third motor 12 is a dual-axis motor, and the first screw 13 is welded to its front and rear output shafts respectively. The sliding frame 11 is rotatably connected to the movable frame 10. The sliding frame 11 is threadedly connected to the corresponding first screw 13. When the lower roller 8 rotates, it drives the connecting plate 9 and the movable frame 10 to rotate synchronously. The sliding frame 11 will not affect the rotation of the movable frame 10.

[0024] like Figure 1 and Figure 4 As shown, the plate shape control assembly includes a fourth motor 14, a second screw 15, a fixed frame 16, and a connecting roller 17. The fourth motor 14 is symmetrically mounted on the left side of the support base 2 via bolts. The output shaft of the fourth motor 14 is connected to the second screw 15. The fixed frame 16 is slidably connected to the second screw 15. The fixed frame 16 is close to the left side wall of the support base 2. A connecting roller 17 is mounted between each pair of fixed frames 16 that are symmetrically arranged front and back by a rotating connection. The connecting roller 17 is made of polyurethane and has a smooth cylindrical outer surface. The hardness of the connecting roller 17 is Shore A 80-90 degrees, so as to provide appropriate pressure and friction during the rolling and shaping of the workpiece, while avoiding damage to the surface of the workpiece.

[0025] During metal rolling operations, the distance between the upper roll 6 and the lower roll 8 in this device must first be precisely adjusted according to the required rolling thickness of the workpiece. The specific operation process is as follows: Start the hydraulic cylinder 3. By controlling the extension or retraction of the telescopic rod of the hydraulic cylinder 3, the connecting frame 4, the first motor 5, and the upper roll 6 move synchronously upward or downward, thereby achieving precise adjustment of the distance between the upper roll 6 and the lower roll 8. After completing the distance adjustment, close the hydraulic cylinder 3. At the same time, the distance between the upper and lower connecting rolls 17 needs to be adjusted. This distance should be adjusted to be slightly larger than the distance between the upper roll 6 and the lower roll 8 so that the connecting rolls 17 can perform initial rolling and shaping operations on the workpiece. In specific operation, the fourth motor 14 is started. By controlling the forward or reverse rotation of the output shaft of the fourth motor 14, the second screw 15 connected to it is rotated, causing the upper and lower fixed frames 16 to move closer or further apart, thereby causing the connecting rollers 17 to move synchronously, achieving precise adjustment of the distance between the two connecting rollers 17. Next, the distance between the two movable frames 10 needs to be adjusted according to the front and rear width of the rolled piece. Specifically, the third motor 12 is started. By controlling the forward or reverse rotation of the output shaft of the third motor 12, the first screw 13 is rotated, causing the two sliding frames 11 to move closer or further apart, thereby causing the movable frames 10 to move closer or further apart along the connecting plate 9, thus achieving adjustment of the distance between the two movable frames 10. After adjustments are completed, the third motor 12 is turned off. Following all the above preparations, the workpiece is pushed from left to right via a conveying device. The workpiece first passes through two connecting rollers 17, which rotate under the friction of the workpiece. This not only assists in conveying the workpiece to the right but also applies pressure, effectively improving its straightness and flatness. Subsequently, the workpiece continues to move to the right between the upper roller 6 and the lower roller 8. During this process, the movable frame 10 limits the front and rear sides of the workpiece, ensuring it is centered and parallel, while simultaneously controlling its width. At this point, the first motor 5 and the second motor 7 are started. The first motor 5 drives the upper roller 6 to rotate, and the second motor 7 drives the lower roller 8 to rotate. Pressure is applied to the workpiece through the upper roller 6 and the lower roller 8, achieving precise control of the workpiece thickness and rolling it to the required specifications. Thus, through the coordinated operation of this device, the shape, thickness, and width of the rolled piece are controlled, and the rolling process can be carried out in an orderly manner during the continuous conveying of the rolled piece.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
