Description

Technical Field

[0001] This utility model belongs to the technical field of plate rolling machines, and in particular relates to a plate rolling machine with adjustable roller spacing. Background Technology

[0002] A plate rolling machine is a mechanical device used to roll metal sheets, steel plates, aluminum plates, and other materials into circular or other curved shapes. It applies pressure to the metal sheet through three or more rollers (usually an upper roller and two lower rollers on either side), causing it to gradually deform under the action of the rollers, ultimately forming the desired curve or circle. Currently, the distance between the two lower rollers in commonly used three-roll plate rolling machines is fixed. This allows for directional processing of the workpiece. However, because plate rolling machines can process workpieces of different materials, and the curvature and shape accuracy of the processed workpieces vary depending on the material, some processed workpieces may deviate from the expected standards in terms of curvature and shape accuracy, thus reducing the processing quality.

[0003] Therefore, we propose a plate rolling machine with adjustable roller spacing. Utility Model Content

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] like Figures 1-4 As shown in the figure, an embodiment of the present invention proposes a plate rolling machine with adjustable roller spacing, including a worktable 1 and fixed plates 2 disposed on both sides of the upper end face of the worktable 1. An upper pressure roller 3 and a lower pressure roller 4 are disposed between the two fixed plates 2. There are two lower pressure rollers 4, which are symmetrical about the upper pressure roller 3. A roller spacing adjustment component 5 is disposed on the fixed plate 2, and a drive component 6 is disposed on one of the fixed plates 2.

[0027] The gap between the two lower pressure rollers 4 can be flexibly adjusted by setting the roller gap adjustment component 5. This can control the curvature and shape accuracy of the processed parts, thereby ensuring that the roundness, curvature, symmetry and other properties of the processed parts meet the expected standards and improve product quality. In addition, the travel distance of the lower pressure rollers 4 is equal when the gap is adjusted, which can avoid the curvature and shape accuracy of the processed parts being affected by the uneven travel distance of the lower pressure rollers 4 when the gap is adjusted.

[0028] The roller spacing adjustment assembly 5 includes a guide groove 51, a slide 52, a moving frame 53, a turntable 55, a push plate 56, a synchronous motor 57, a support frame 58, and a fixed frame 59.

[0029] Two guide grooves 51 are provided, and the two guide grooves 51 correspond to the positions of the two lower pressure rollers 4 respectively. The sliding grooves 52 are opened on the upper and lower sides of the guide grooves 51. The movable frame 53 is slidably connected to the inner side of the guide grooves 51. The two ends of the lower pressure rollers 4 are rotatably connected to the movable frame 53 on the fixed plate 2. Guide blocks 54 are provided on the upper and lower sides of the wall opposite to the fixed plate 2 of the movable frame 53. The guide blocks 54 on the movable frame 53 are slidably connected to the inner side of the sliding grooves 52 on the upper and lower sides of the guide groove 51 to which the movable frame 53 is slidably connected. The turntable 55 is rotatably connected to the fixed plate 2, and the turntable 55 is located between two guide grooves 51 on the fixed plate 2. Two push plates 56 are provided, and the two push plates 56 are rotatably connected to the turntable 55. The ends of the two push plates 56 away from the turntable 55 are respectively rotatably connected to two guide blocks 54. The synchronous motor 57 is located on one side of the turntable 55, and the output end of the synchronous motor 57 is connected to the turntable 55. The support frame 58 is located on the synchronous motor 57, and the fixed frame 59 is located below the synchronous motor 57. The fixed frame 59 is connected to the worktable 1, and the support frame 58 on the synchronous motor 57 is connected to the fixed frame 59.

[0030] It should be noted that the synchronous motors 57 of the two roller spacing adjustment components 5 drive and rotate at the same speed, which ensures that the spacing between the two lower pressure rollers 4 can be kept stable.

[0031] In this embodiment, when it is necessary to adjust the distance between the two lower pressure rollers 4, the synchronous motor 57 is started. The synchronous motor 57 drives the turntable 55 to rotate. The turntable 55 drives the two movable frames 53 on the fixed plate 2 to move along the guide groove 51 in opposite or opposite directions through the push plate 56. The movable frames 53 drive the lower pressure rollers 4 to move. When the lower pressure rollers 4 move to the appropriate position, the synchronous motor 57 is turned off.

[0032] The guide block 54 and the slide 52 are designed to guide and limit the movement of the moving frame 53, thus preventing the moving frame 53 from rotating due to force during movement.

[0033] The drive assembly 6 includes limiting grooves 61 formed on the upper and lower sides of the guide groove 51 on the fixed plate 2 and a connecting frame 62 set on one side of the fixed plate 2. There are two connecting frames 62, and the two connecting frames 62 correspond to the positions of the two guide grooves 51 on the fixed plate 2. Two limiting blocks 63 are set on the side wall of the connecting frame 62 opposite to the fixed plate 2. The two limiting blocks 63 slide in the guide grooves 51 on the upper and lower sides of the guide grooves 51. A servo motor 64 is set on the connecting frame 62, and the output end of the servo motor 64 is connected to the lower pressure roller 4 corresponding to the guide groove 51.

[0034] It should be noted that the cross-section of the limiting groove 61 is an isosceles trapezoid, and the cross-section and size of the limiting block 63 are adapted to the limiting groove 61, so that the connecting frame 62 can be slidably connected to the fixed plate 2.

[0035] In this embodiment, during the movement of the lower pressure roller 4, the connecting frame 62 will move along the limiting groove 61 via the moving frame 53, and the servo motor 64 on the connecting frame 62 will also move along with the movement of the connecting frame 62.

[0036] A cylinder 8 is provided on the upper end face of the fixed plate 2. A through groove 7 is provided on the fixed plate 2. A movable block 70 is slidably arranged in the through groove 7. The cross-section of the movable block 70 is I-shaped. The two ends of the upper pressure roller 3 are rotatably connected to the movable blocks 70 on the two fixed plates 2. The output end of the cylinder 8 is connected to the movable block 70 inside the through groove 7.

[0037] The cylinder 8 is designed to drive the upper pressure roller 3 to move vertically via the moving block 70. The moving block 70, with its I-shaped cross-section, makes the sliding of the moving block 70 on the fixed plate 2 more stable.

[0038] Working principle:

[0039] When it is necessary to adjust the distance between the two lower pressure rollers 4, start the synchronous motor 57. The synchronous motor 57 drives the turntable 55 to rotate. The turntable 55 drives the two movable frames 53 on the fixed plate 2 to move along the guide groove 51 in opposite or opposite directions through the push plate 56. The movable frames 53 drive the lower pressure rollers 4 to move. During the movement, the lower pressure rollers 4 will drive the connecting frame 62 to move along the limit groove 61 through the movable frame 53. The servo motor 64 on the connecting frame 62 also moves with the movement of the connecting frame 62. When the lower pressure rollers 4 move to the appropriate position, the synchronous motor 57 can be turned off.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
