Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, specifically to a thin-walled plate rolling machine with adjustable roller diameter. Background Technology

[0002] A plate rolling machine is a device that bends sheet materials into arc shapes. Through the plate rolling operation of the plate rolling machine, the sheet material can be formed into the required curved shape structure, such as metal sheet or other sheet material with deformation properties. Through bending processing and subsequent welding or other processing, various structural shapes required by users can be formed.

[0003] A search revealed a thin-walled plate rolling machine with adjustable roller diameter, authorized by announcement number CN222198452U. This utility model utilizes rotating shafts on both sides to simultaneously drive the worm gears in the lifting components on both sides, thereby achieving simultaneous lifting and lowering of both ends of the upper roller shaft. This enables stable lifting and lowering adjustment of the upper roller shaft. Furthermore, the upper roller shaft lifting and lowering adjustment method is more stable than the lower roller shaft adjustment method, reducing the problems of height difference and offset between roller shafts due to spacing adjustment.

[0004] However, the existing plate rolling machines mentioned above do not have a limiting structure when used with plates of different lengths, which can easily cause the plates to deviate during rolling. To address this, we propose a thin-walled plate rolling machine with adjustable roller diameter. Utility Model Content

[0005] This utility model proposes a thin-walled plate rolling machine with adjustable roller diameter, which solves the problem mentioned in the background art that existing plate rolling machines do not have a limiting structure when used with plates of different lengths, which easily leads to the plate shifting during rolling.

[0006] The technical solution of this utility model is as follows:

[0007] A thin-walled plate rolling machine with adjustable roller diameter includes an outer shell, a rotating roller rotatably connected to the inner side of the outer shell, a limit structure connecting the rotating roller and the outer shell, and an adjusting roller rotatably arranged on the inner side of the outer shell for adjusting the diameter.

[0008] The limiting structure includes a limiting plate fixedly connected to one end of the outer surface of the rotating roller, a movable plate movably sleeved on the outer surface of the rotating roller, a fixed plate fixedly connected to the inner side of the outer shell, a limiting cylinder fixedly connected to the surface of the fixed plate, a connecting plate fixedly connected between the output end of the limiting cylinder and the movable plate, and a guide component connected to the outer surface of the fixed plate.

[0009] As a further technical solution of this utility model, the guiding assembly includes a guide plate fixedly connected to the outer surface of the fixed plate, a protrusion block fixedly connected to the inner surface of the guide plate, and a guide roller rotatably connected to the inner side of the protrusion block.

[0011] As a further technical solution of this utility model, a reduction motor is fixedly connected to one end of the rotating roller on the inner side of the outer shell. The reduction motor is used to drive the rotating roller to rotate. A rotating frame is rotatably connected to one end of the outer surface of the outer shell near the rotating roller. The rotating frame is used to maintain the stability of the rotating roller. A telescopic cylinder is hinged between the outer shell and the rotating frame. The extension of the telescopic cylinder realizes the support of the rotating frame for the rotating roller. The retraction of the telescopic cylinder realizes the separation of the rotating frame and the rotating roller. Two sets of connecting blocks are rotatably connected to both ends of the adjusting roller. A set of jacking cylinders is connected between the connecting blocks and the outer shell. The position of the adjusting roller is adjusted by the extension or retraction of the jacking cylinders.

[0012] As a further technical solution of this utility model, the movable plate and the connecting plate slide back and forth along the length direction of the rotating roller. The position of the connecting plate and the movable plate on the outer surface of the rotating roller is adjusted by the extension and contraction of the limiting cylinder. The number of the limiting cylinders is several sets and they are distributed in a ring array. The length between the movable plate and the limiting plate is adjusted by the back and forth movement of the movable plate on the surface of the rotating roller.

[0013] As a further technical solution of this utility model, the number of the guide components is several groups and they are distributed in a ring array. The guide roller and the rotating roller are connected by rolling, and the guide roller and the rotating roller are always in line contact.

[0014] As a further technical solution of this utility model, the number of micro cylinders on the same cross section is several groups and they are distributed in a ring array. Each group of micro cylinders on the cross section is a set of actuating components.

[0015] As a further technical solution of this utility model, the jacking components on the outer surface of the central column are a number of groups and are arranged in a "I"-shaped array. The arc surface of the arc plate matches the outer tube. The overall shaft roller diameter of the adjustment roller is adjusted by extending or contracting the arc plate.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] In this invention, the limiting structure can conveniently limit the length of the rotating roller during use, thereby enabling the sheet material to be bent and processed better as a whole without causing large tilting or offset. This effectively reduces errors during processing and can also position and guide the rotating roller, resulting in better rotation performance. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0026] like Figures 1-4As shown, this embodiment proposes a thin-walled plate rolling machine with adjustable roller diameter, including an outer shell 1. A rotating roller 2 is rotatably connected to the inner side of the outer shell 1. A limit structure 3 is connected between the rotating roller 2 and the outer shell 1. An adjusting roller 4 is rotatably arranged on the inner side of the outer shell 1 to adjust the diameter. A reduction motor 5 is fixedly connected to one end of the rotating roller 2 on the inner side of the outer shell 1 to drive the rotating roller 2 to rotate. A rotating frame 6 is rotatably connected to one end of the outer surface of the outer shell 1 near the rotating roller 2 to maintain the stability of the rotating roller 2. A telescopic cylinder 7 is hinged between the outer shell 1 and the rotating frame 6. The extension of the telescopic cylinder 7 supports the rotating frame 6 for the rotating roller 2, and the retraction of the telescopic cylinder 7 separates the rotating frame 6 from the rotating roller 2. Two sets of connecting blocks 9 are rotatably connected to both ends of the adjusting roller 4. A set of actuating cylinders 8 are connected between the connecting blocks 9 and the outer shell 1 to adjust the position of the adjusting roller 4 by extending or retracting the actuating cylinders 8.

[0027] The limiting structure 3 includes a limiting plate 31 fixedly connected to one end of the outer surface of the roller 2, a movable plate 32 movably sleeved on the outer surface of the roller 2, a fixed plate 33 fixedly connected to the inner side of the outer shell 1, a limiting cylinder 34 fixedly connected to the surface of the fixed plate 33, a connecting plate 35 fixedly connected between the output end of the limiting cylinder 34 and the movable plate 32, and a guide component 36 connected to the outer surface of the fixed plate 33.

[0028] The guide assembly 36 includes a guide plate 361 fixedly connected to the outer surface of the fixed plate 33. A protrusion 362 is fixedly connected to the inner surface of the guide plate 361, and a guide roller 363 is rotatably connected to the inner side of the protrusion 362. The movable plate 32 and the connecting plate 35 slide back and forth along the length direction of the rotating roller 2. The position of the connecting plate 35 and the movable plate 32 on the outer surface of the rotating roller 2 is adjusted by the extension and retraction of the limiting cylinder 34. The limiting cylinder 34 is a group of several sets and is distributed in a ring array. The length between the movable plate 32 and the limiting plate 31 is adjusted by the back and forth movement of the movable plate 32 on the surface of the rotating roller 2. The guide assembly 36 is a group of several sets and is distributed in a ring array. The guide roller 363 is in rolling connection with the rotating roller 2, and the guide roller 363 is always in line contact with the rotating roller 2.

[0029] In this embodiment, the length of the rotating roller 2 can be conveniently limited during use, so that the board can be bent and processed better as a whole, without causing the board to tilt or deviate significantly. This effectively reduces the errors generated during processing. At the same time, the rotating roller 2 can be positioned and guided, making the rotation of the roller 2 more effective. Example 2

[0030] like Figure 5As shown, based on Embodiment 1, an adjustment roller 4 is also proposed, which includes an outer tube 41, a central column 42 fixedly connected to the axis of the outer tube 41, a micro cylinder 43 fixedly connected to the surface of the central column 42, and an arc plate 44 fixedly connected to the output end of the micro cylinder 43.

[0031] The number of miniature cylinders 43 on the same cross section is several groups and they are arranged in a ring array. Each group of miniature cylinders 43 on the cross section is a set of actuating components. The actuating components on the outer surface of the central column 42 are several groups and they are arranged in a "I"-shaped array. The arc surface of the arc plate 44 matches the outer tube 41. The overall shaft roller diameter of the adjusting roller 4 is adjusted by extending or contracting the arc plate 44.

[0032] In this embodiment, during use, the diameter of the adjusting roller 4 as a whole can be freely adjusted by extending or retracting the micro cylinder 43. In conjunction with the pushing and extending of the pushing cylinder 8, the adjusting roller 4 can be freely moved to the required range, thereby forming a better plate rolling effect.

[0033] In summary, the working principle of this utility model is as follows:

[0034] During use, the user can place the sheet material between the rotating roller 2 and the adjusting roller 4. The geared motor 5 drives the rotating roller 2 to rotate. The rotation of the rotating roller 2, in conjunction with the actuating cylinder 8, actuates the connecting block 9, causing the adjusting roller 4 to contact the lower surface of the sheet material, while the rotating roller 2 contacts the upper surface of the sheet material. The rotation of the rotating roller 2 provides the power for conveying and bending. Combined with the pressure exerted on the sheet material by the adjusting roller 4, the sheet material can be bent while being conveyed. At the same time, the pressure effect of the adjusting roller 4 on the sheet material can be adjusted by extending and retracting the actuating cylinder 8, which can form sheets with different degrees of curvature.

[0035] During use, when the length of the sheet material is small, the limiting cylinder 34 can extend to push the connecting plate 35, causing the connecting plate 35 and the movable plate 32 to move towards the limiting plate 31. When the distance between the movable plate 32 and the limiting plate 31 is equal to the length of the sheet material, the sheet material can then be placed between the rotating roller 2 and the adjusting roller 4 for processing. The limiting effect of the movable plate 32 effectively prevents the processing error caused by the displacement of the bent sheet material, resulting in higher bending processing accuracy. Conversely, the retraction of the limiting cylinder 34 makes the equipment suitable for longer sheets material, meeting the bending processing needs of different users for sheets of different lengths. At the same time, the guide roller 363 guides the rotation of the rotating roller 2, reducing the error of the equipment operation.

[0036] When it is necessary to adjust the overall roller diameter of the adjusting roller 4, several sets of micro cylinders 43 can be extended outward to the same distance at the same time, so that several sets of annular arc plates 44 can be extended outward, and several sets of arc plates 44 can form a large diameter roller body. Conversely, the overall diameter can be reduced by shrinking the micro cylinders 43, so that roller bodies of different diameters can be formed according to the actual needs of use, thereby meeting the different processing requirements of the equipment.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
