Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate rolling machine technology, and more specifically, to a thin-walled plate rolling machine with adjustable roller diameter. Background Technology
[0002] Plate rolling machines can efficiently roll metal sheets into various shapes, such as cylinders and cones, which greatly improves production efficiency. Compared with traditional manual operation, mechanized processing is not only faster but also more accurate, reducing repetitive labor and human error. At the same time, the use of plate rolling machines reduces reliance on skilled workers and lowers labor costs.
[0003] Traditional plate rolling machines use three or four axes for rolling. If the roller diameter cannot be adjusted according to the actual situation of the plate, the rolled workpiece may have deviations in size, shape or surface quality. These deviations may affect the performance and use of the workpiece, or even lead to the scrapping of the workpiece. Therefore, it is necessary to improve and optimize the plate rolling machine.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a movable ring that slides along the surface of a bidirectional threaded rod.

When it is necessary to disassemble the roll plate, simply lower the mounting plate and pull the roll plate out from the right side of the thin-walled curved panel. Attached Figure Description

[0024] 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.
[0025] like Figures 1 to 7 As shown, this utility model provides a thin-walled plate rolling machine with adjustable roller diameter, including a base 1. A fixed support plate 2 is fixedly connected to the upper part of the base 1. A slider 3 is movably connected inside the fixed support plate 2. A rotating shaft 4 is rotatably connected inside the slider 3. A limiting turntable 5 is fixedly connected to the right side of the rotating shaft 4. A thin-walled curved plate 6 is movably connected inside the limiting turntable 5. A bidirectional threaded rod 7 is movably connected inside the rotating shaft 4. An internal threaded hinge 8 is threadedly connected to the surface of the bidirectional threaded rod 7. A hinge rod 9 is hinged to the surface of the internal threaded hinge 8. A hinge block 10 is hinged to the end of the hinge rod 9 away from the internal threaded hinge 8. One side of the hinge block 10 is fixedly connected to the inner surface of the thin-walled curved plate 6. A locking structure is provided on the left side of the rotating shaft 4.
[0026] When the roller diameter needs to be adjusted, the operator moves the left iron ring 29 when the plate rolling machine stops, causing the limiting strip 26 to disengage from the limiting groove 24. At this time, the adjusting turntable 27 is rotated, causing the bidirectional threaded rod 7 to rotate inside the rotating shaft 4. Then, because the internal threaded hinge 8 is threadedly connected to the bidirectional threaded rod 7, the two internal threaded hinges 8 move relative to each other. Since the thin-walled curved panel 6 is hinged between the hinge block 10 and the internal threaded hinge 8, and the limiting turntable 5 limits the thin-walled curved panel 6, the diameter of the thin-walled curved panel 6 can be adjusted. Then, the left iron ring 29 is pushed to the right, causing the movable ring 25 to move to the right, and then the limiting strip 26 enters the limiting groove 24. Subsequently, during plate rolling, the bidirectional threaded rod 7 rotates with the rotation of the rotating shaft 4.
[0027] Among them, an electric push rod 11 is fixedly connected to the upper surface of the base 1, and an installation plate 12 is fixedly connected to the output shaft of the electric push rod 11. A telescopic rod 13 is fixedly connected between the installation plate 12 and the base 1. An arc plate 14 is fixedly installed on the upper part of the installation plate 12. The curvature of the arc plate 14 is equal to the curvature of the thin-walled curved plate 6. A ball bearing 31 is fixedly installed inside the arc plate 14.
[0028] The operator controls the start of the electric push rod 11 through the controller 30. The height of the mounting plate 12 is adjusted by the up and down movement of the output shaft of the electric push rod 11. Then, the telescopic rod 13 limits the mounting plate 12, thereby driving the arc plate 14 to rise and fall. Since the curvature of the arc plate 14 is equal to the curvature of the thin-walled curved panel 6, the arc plate 14 can always conform to the outer surface of the thin-walled curved panel 6, thus providing a certain support force to the right side of the thin-walled curved panel 6. However, since the ball bearing 31 is located between the arc plate 14 and the thin-walled curved panel 6, the sliding friction is converted into rolling friction. When it is necessary to disassemble the bent plate, simply start the electric push rod 11 to move the arc plate 14 downward, and the rolled plate can be moved out from the right side of the thin-walled curved panel 6. When it is necessary to bend the plate, the ball bearing 31 provides support force to the thin-walled curved panel 6 through the start of the electric push rod 11.
[0029] The fixed support plate 2 is rotatably connected to a hollow rolling roller 15. The right end of the hollow rolling roller 15 is rotatably connected to the inside of the base 1. The left end of the hollow rolling roller 15 is fixedly connected to a pulley 16. A belt 17 is connected between the front and rear pulleys 16. The upper surface of the fixed support plate 2 is fixedly connected to a first motor 18. The output shaft of the first motor 18 is fixedly connected to the left end of the front hollow rolling roller 15.
[0030] The movement of the output shaft of the first motor 18 drives the front hollow rolling roller 15 to rotate inside the base 1 and the fixed support plate 2. At the same time, due to the transmission effect of the pulley 16 and the belt 17, the front and rear hollow rolling rollers 15 rotate at the same speed.
[0031] The upper surface of the slider 3 is fixedly connected to the second motor 19, the output shaft of the second motor 19 is fixedly connected to the first gear 20, the surface of the rotating shaft 4 is fixedly connected to the second gear 21, and the first gear 20 and the second gear 21 mesh with each other.
[0032] The rotation of the output of the second motor 19 drives the rotation of the first gear 20. However, due to the meshing of the first gear 20 and the second gear 21, the rotating shaft 4 is driven to rotate inside the slider 3, thereby driving the rotation of the limiting turntable 5, and then driving the rotation of the thin-walled curved panel 6.
[0033] Among them, a cylinder 22 is fixedly installed on the upper part of the fixed support plate 2, and the output shaft of the cylinder 22 is fixedly connected to the upper part of the slider 3.
[0034] The movement of the output shaft of cylinder 22 causes the slider 3 to move up and down inside the fixed support plate 2, thereby causing the thin-walled curved panel 6 to rise and fall, thus better adjusting the diameter of the roller shaft.
[0035] The locking structure includes a fixed ring 23 fixedly connected to the left surface of the rotating shaft 4, a limit groove 24 on the left surface of the fixed ring 23, a movable ring 25 movably connected to the surface of the bidirectional threaded rod 7, a limit strip 26 fixedly connected to the right side of the movable ring 25, and an adjusting turntable 27 fixedly connected to the left end of the bidirectional threaded rod 7.
[0036] By cooperating with the limiting groove 24 and the limiting strip 26, the bidirectional threaded rod 7 can rotate with the rotating shaft 4 when the rotating shaft 4 needs to rotate. By moving the movable ring 25 to the left, the limiting strip 26 is disengaged from the inside of the limiting groove 24. Then, by rotating the adjusting turntable 27, the bidirectional threaded rod 7 is driven to rotate inside the rotating shaft 4.
[0037] Among them, a magnetic ring 28 is fixedly connected to the surface of the fixed ring 23, and an iron ring 29 is fixedly connected to the surface of the movable ring 25. There are two iron rings 29.
[0038] The magnetic force between the magnetic ring 28 and the right iron ring 29 makes the limiting strip 26 firmly embedded in the limiting groove 24, preventing the movable ring 25 from separating from the fixed ring 23.
[0039] The upper surface of the base 1 is fixedly equipped with a controller 30, which is electrically connected to the electric push rod 11, the first motor 18, the second motor 19, and the cylinder 22.
[0040] The controller 30 controls the start of the electric push rod 11, the first motor 18, the second motor 19, and the cylinder 22, making it convenient for staff to operate the machine to roll the plate.
[0041] Working principle and usage process of this utility model:
[0042] When the roller diameter needs to be adjusted, the operator moves the left iron ring 29 when the plate rolling machine stops, causing the limiting strip 26 to disengage from the limiting groove 24. At this time, the adjusting turntable 27 is rotated, causing the bidirectional threaded rod 7 to rotate inside the rotating shaft 4. Then, because the internal threaded hinge 8 is threadedly connected to the bidirectional threaded rod 7, the two internal threaded hinges 8 move relative to each other. Since the thin-walled curved panel 6 is hinged between the hinge block 10 and the internal threaded hinge 8, and the limiting turntable 5 limits the thin-walled curved panel 6, the diameter of the thin-walled curved panel 6 can be adjusted. Then, the left iron ring 29 is pushed to the right, causing the movable ring 25 to move to the right, and then the limiting strip 26 enters the limiting groove 24. Subsequently, during plate rolling, the bidirectional threaded rod 7 rotates with the rotation of the rotating shaft 4.
[0043] The operator controls the start of the electric push rod 11 through the controller 30. The height of the mounting plate 12 is adjusted by the up and down movement of the output shaft of the electric push rod 11. Then, the telescopic rod 13 limits the mounting plate 12, thereby driving the arc plate 14 to rise and fall. Since the curvature of the arc plate 14 is equal to the curvature of the thin-walled curved panel 6, the arc plate 14 can always conform to the outer surface of the thin-walled curved panel 6, thus providing a certain support force to the right side of the thin-walled curved panel 6. However, since the ball bearing 31 is located between the arc plate 14 and the thin-walled curved panel 6, the sliding friction is converted into rolling friction. When it is necessary to disassemble the bent plate, simply start the electric push rod 11 to move the arc plate 14 downward, and the rolled plate can be moved out from the right side of the thin-walled curved panel 6. When it is necessary to bend the plate, the ball bearing 31 provides support force to the thin-walled curved panel 6 through the start of the electric push rod 11.
[0044] The movement of the output shaft of the first motor 18 drives the front hollow rolling roller 15 to rotate inside the base 1 and the fixed support plate 2. At the same time, due to the transmission effect of the pulley 16 and the belt 17, the front and rear hollow rolling rollers 15 rotate at the same speed.
[0045] The rotation of the output of the second motor 19 drives the rotation of the first gear 20. However, due to the meshing of the first gear 20 and the second gear 21, the rotating shaft 4 is driven to rotate inside the slider 3, thereby driving the rotation of the limiting turntable 5, and then driving the rotation of the thin-walled curved panel 6.
[0046] The movement of the output shaft of cylinder 22 causes the slider 3 to move up and down inside the fixed support plate 2, thereby causing the thin-walled curved panel 6 to rise and fall, thus better adjusting the diameter of the roller shaft.
[0047] By cooperating with the limiting groove 24 and the limiting strip 26, the bidirectional threaded rod 7 can rotate with the rotating shaft 4 when the rotating shaft 4 needs to rotate. By moving the movable ring 25 to the left, the limiting strip 26 is disengaged from the inside of the limiting groove 24. Then, by rotating the adjusting turntable 27, the bidirectional threaded rod 7 is driven to rotate inside the rotating shaft 4.
[0048] The magnetic force between the magnetic ring 28 and the right iron ring 29 makes the limiting strip 26 firmly embedded in the limiting groove 24, preventing the movable ring 25 from separating from the fixed ring 23.
[0049] The controller 30 controls the start of the electric push rod 11, the first motor 18, the second motor 19, and the cylinder 22, making it convenient for staff to operate the machine to roll the plate.
