Description

Technical Field

[0001] This utility model relates to the field of steel drum processing technology, and in particular to a device for adjusting the curvature of rolled steel drums. Background Technology

[0002] In the manufacturing process of steel drums, the rolling process is a crucial step in processing flat steel sheets into cylindrical drum bodies. It directly determines the roundness accuracy, dimensional consistency, and processing quality of subsequent welding and sealing processes. To ensure the stability and accuracy of the rolling process and prevent the steel sheets from shifting, wrinkling, or deforming during rolling, a specialized support mechanism is usually needed to position and support the steel sheets or the drum body during rolling. The rolling structure and the support mechanism work together to complete the rolling process of the steel drum.

[0003] Steel drum rolling equipment typically consists of a fixed rolling assembly and a support assembly. The rolling assembly usually comprises a drive roller and a driven roller, and the rolling of the steel drum is achieved by adjusting the distance between the drive roller and the driven roller. The support assembly usually consists of support rollers or support platforms with fixed spacing or a small range of adjustability. However, with the diversification of market demand for steel drum specifications, the production process often requires switching between processing steel drums of different diameters and lengths. The structural defects of existing rolling equipment have gradually become apparent, making it difficult to meet the demand for efficient and precise rolling of steel drums of various specifications.

[0004] Specifically, the existing rolling structure has a limited adjustment range, with a fixed adjustment stroke between the drive roller and the driven roller, making it suitable only for rolling a few types of steel drums with similar specifications. When processing steel drums with significantly different diameters, the existing rolling structure is inconvenient for effective adjustment, necessitating the replacement of the entire rolling assembly. This not only increases equipment investment costs but also prolongs production changeover time, severely impacting production efficiency. Therefore, this invention proposes a novel solution.

Simultaneously, the hydraulic rod inside the first fixed bracket can push the drive roller bracket to move smoothly along the guide rod, fine-tuning the position of the drive roller. This allows the rolling space formed by the drive roller and the driven roller to adapt to the processing of various specifications of steel drums, from small to large diameters. Compared to existing equipment that requires replacing the entire rolling assembly, this device does not require disassembling core components; specification switching can be completed solely through mechanical adjustment.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a steel barrel rolling arc adjustment device. The base frame 1 serves as the installation reference for the entire device. It is made of Q235 carbon steel and welded together. The structure is stable and has a strong load-bearing capacity, providing stable support for each functional component and ensuring that the device as a whole does not deform or shake during the rolling process.

[0022] The first auxiliary support frame 2 is U-shaped and is fixedly connected to the right end of the base frame 1 by bolts. It is made of 45 steel and has two first positioning holes 23 on its surface, which correspond precisely to the first positioning holes 23 on the surface of the movable frame 9, providing a reliable foundation for fixing the position of the movable frame 9.

[0023] The first fixed frame 3 is fixedly connected to the upper left side of the base frame 1 by welding. It is made of steel plate bending and has reserved installation space inside to adapt to the hydraulic rod 4. The overall structure is rigid and can resist the lateral impact force during rolling, ensuring the stability of the drive roller 7 adjustment process.

[0024] The hydraulic rod 4 is fixedly connected inside the first fixed frame 3, and its output end is welded and fixed to the drive roller bracket 5. The bidirectional hydraulic rod can precisely control the displacement of the drive roller bracket 5 and realize the fine adjustment of the position of the drive roller 7.

[0025] The drive roller bracket 5 has a frame structure. Two guide rods 6 are fixedly connected to the left end, the drive motor 8 is fixedly connected to the upper end by bolts, and the lower end is rotatably connected to the drive roller 7 by bearings. It is made of high-strength aluminum alloy, which balances rigidity and lightness, and reduces the drive load of the hydraulic rod 4.

[0026] The guide rod 6 is made of 45 steel with chrome plating, which has a smooth and wear-resistant surface. It is slidably connected to the first fixed frame 3, with high guiding accuracy. It can limit the offset and tilt of the drive roller bracket 5 and ensure the straightness of the movement trajectory of the drive roller 7.

[0027] The drive roller 7 is rotatably connected to the drive roller bracket 5 via bearings and is fixed to the output end of the drive motor 8 via a coupling. Its surface is hardened, making it highly wear-resistant and capable of providing stable driving force and extrusion force for rolling steel drum plates.

[0028] The drive motor 8 is a variable frequency motor, which can adjust the speed according to the thickness of the sheet and the diameter of the steel drum. It is fixed to the upper end of the drive roller bracket 5 by bolts. The power output is stable, ensuring that the rolling process is uniform and controllable, and avoiding wrinkles on the sheet due to speed fluctuations.

[0029] The movable frame 9 is slidably connected to the first slide groove 21 of the base frame 1 via the first slider 22 at the lower end, and is slidably engaged with the limit frame 25 on the front and rear sides. The second fixed bracket 10 is welded and fixed at the upper end. The material is Q235 carbon steel, and the surface is sprayed with anti-rust paint to extend the service life. It can move flexibly along the length of the base frame 1.

[0030] The second fixed bracket 10 is welded to the upper end of the movable frame 9. Two “V”-shaped driven roller brackets 11 are fixedly connected to the end near the first fixed bracket 3. The “V” angle is designed according to the common steel drum specifications to provide stable installation support for the driven roller 12 and ensure that the plate is subjected to uniform force when rolling.

[0031] The driven roller bracket 11 is welded and fixed to the second fixed bracket 10. The driven roller 12 is rotatably connected to the inner side through a bearing. The two brackets are symmetrically arranged and are made of No. 45 steel. They have high structural strength and can withstand the reaction force of the plate during the rolling process.

[0032] The second auxiliary support frame 13 is U-shaped and is fixedly connected to the left end of the base frame 1. The two corners at the end away from the base frame 1 are rounded. Multiple second positioning holes 24 are opened on the surface. The material is 45 steel, which provides sliding rails and fixed points for the connecting frame 16.

[0033] The second fixing frame 14 is welded to the left end of the base frame 1 and the first fixing frame 3 respectively. The internal rotating shaft 15 is rotatably connected by bearings. It is made of steel plate stamping and has a compact structure, which can provide stable support for the rotating shaft 15 and ensure smooth rotation without jamming.

[0034] The rotating shaft 15 is made of 40Cr material with surface quenching and tempering treatment, and has high torsional strength. It is rotatably connected to the second fixed frame 14, and the surface is fixedly connected to the connecting frame 16 by a flat key, which can drive the connecting frame 16 to rotate flexibly, thereby realizing the angle adjustment of the first support roller 18.

[0035] The connecting frame 16 is fixed to the surface of the rotating shaft 15 by a flat key and is slidably connected to the second auxiliary support frame 13. The first support frame 17 is welded and fixed at the upper end. The material is Q235 carbon steel and the angle can be adjusted with the rotation of the rotating shaft 15 to adapt to the feeding needs of steel drum plates of different specifications.

[0036] The first support frame 17 is welded to the upper end of the connecting frame 16, and the first support roller 18 is rotatably connected to it through a bearing. The structure is simple and the rotation is flexible, which can provide stable support for the feeding end of the steel drum plate and prevent the plate from shifting during feeding.

[0037] The first support roller 18 is rotatably connected to the first support frame 17. It is made of stainless steel and has a polished surface that is smooth and burr-free. This reduces frictional resistance when feeding the sheet material and prevents scratches or wrinkles on the sheet surface.

[0038] The second support frame 19 is welded to the upper end of the base frame 1 and is arranged in a "V" shape. The second support roller 20 is rotatably connected to the inside through bearings. It is made of No. 45 steel and can provide support for the middle of the plate, enhancing the stability of the conveying process.

[0039] The second support roller 20 is rotatably connected to the second support frame 19. Its surface is polished and, together with the "V" shaped layout, it forms a lateral limit on the plate to prevent the plate from moving left and right during the conveying process, ensuring that the plate enters the rolling area along the preset path.

[0040] The first slide groove 21 is located at the right end of the base frame 1, and its inner wall is covered with a polytetrafluoroethylene wear-resistant layer. It slides in cooperation with the first slider 22 at the lower end of the movable frame 9, with a low coefficient of friction, ensuring that the movable frame 9 moves smoothly without jamming.

[0041] The first slider 22 is welded to the lower end of the movable frame 9 and is in clearance fit with the first slide groove 21. The end is provided with a rounded transition to avoid hard collision with the end of the slide groove during movement and to protect the structural integrity.

[0042] The first positioning holes 23 are respectively opened on the surface of the movable frame 9 and the surface of the first auxiliary support frame 2. The position of the movable frame 9 is fixed by bolt locking, and the connection is stable and not easy to loosen.

[0043] The second positioning hole 24 is opened at the arc end of the second auxiliary support frame 13 and the lower end of the connecting frame 16. The hole diameter is 10mm and it is compatible with M8 bolts. It is used to bolt the connecting frame 16 and realize the angle locking of the first support roller 18.

[0044] The limiting frame 25 is L-shaped and welded to the upper end of the base frame 1. It is symmetrically arranged on the front and rear sides of the movable frame 9 and slides with the movable frame 9. It can limit the forward and backward movement of the movable frame 9, ensure the stability of the position during movement, and not affect the rolling accuracy.

[0045] Working principle: Before rolling the steel drum into rounds, the equipment parameters need to be adjusted according to the diameter and length specifications of the steel drum to be processed to ensure rolling accuracy and stability.

[0046] The movable frame 9 is slidably engaged with the first sliding groove 21 on the right side of the base frame 1 via the first slider 22 at its lower end. At the same time, the two "L"-shaped limiting frames 25 symmetrically arranged on the upper end of the base frame 1 provide rigid constraints on the forward and backward displacement of the movable frame 9, ensuring that the movable frame 9 can only move smoothly along the length of the base frame 1. When the operator pushes the movable frame 9, it drives the second fixed bracket 10 fixed at its upper end to move synchronously. This causes the two driven roller brackets 11 arranged in a "V" shape on the left side of the second fixed bracket 10 and the driven roller 12 rotatably connected on the inner side to move accordingly, thereby achieving a coarse adjustment of the distance between the driven roller 12 and the drive roller 7. When the distance meets the requirements of matching the diameter of the steel drum to be processed, the movable frame 9 is firmly locked to the "U"-shaped first auxiliary support frame 2 fixed on the right side of the base frame 1 by passing bolts through the first positioning holes 23 corresponding to the surface of the first auxiliary support frame 2 and the movable frame 9, thus completing the fixation of the position of the driven roller 12.

[0047] The hydraulic rod 4, which is fixedly installed inside the first fixed frame 3, is activated, and its output end pushes the drive roller bracket 5 to move horizontally. The two guide rods 6 fixed at the left end of the drive roller bracket 5 form a sliding fit with the first fixed frame 3, effectively limiting the offset and tilt of the drive roller bracket 5 and ensuring the straightness of its movement trajectory. By controlling the extension and retraction of the hydraulic rod 4, the drive roller 7 installed on the drive roller bracket 5 is driven to achieve fine adjustment of its height and horizontal position, so that the drive roller 7 and the two driven rollers 12 form a triangular clamping space that meets the requirements of the rolling process, ensuring that the steel drum plate can be stably clamped and gradually bent.

[0048] In the auxiliary support assembly, two connecting frames 16 are rotatably connected to a second fixed frame 14, which is fixed to the left end of the base frame 1 and the first fixed frame 3, respectively, via a rotating shaft 15. The connecting frame 16 and the "U"-shaped second auxiliary support frame 13 fixed to the left end of the base frame 1 form a sliding fit. According to the feeding angle requirements of the steel drum plate, rotating the connecting frame 16 drives the first support frame 17 fixed at its upper end and the first support roller 18 rotatably connected to its inner side to adjust the tilt angle synchronously, so that the first support roller 18 can fit the force direction of the plate feeding end. When the angle is adjusted to the correct position, the connecting frame 16 and the second auxiliary support frame 13 are locked by bolts passing through multiple second positioning holes 24 opened at the arc end of the second auxiliary support frame 13 and the corresponding second positioning holes 24 at the lower end of the connecting frame 16, thereby fixing the angle of the first support roller 18. At the same time, the two second support frames 19 arranged in a "V" shape at the upper end of the base frame 1 and the second support roller 20 rotatably connected to its inner side maintain a preset posture, providing stable support for the middle of the steel drum plate.

[0049] One end of the flat steel drum plate is fed into the feed end of the equipment, and the feed end of the plate contacts the first support roller 18. The first support roller 18 reduces the feeding resistance of the plate by rotating itself, and at the same time restricts the lateral displacement of the plate. The middle part of the plate is placed on two second support rollers 20 arranged in a "V" shape. The second support rollers 20 assist the plate to be transported smoothly by rotating, and the "V" shape layout can form a lateral limit on the plate, preventing the plate from moving left and right during the transport process, and ensuring that the plate enters the rolling area accurately along the preset path.

[0050] The drive motor 8, fixed at the upper end of the drive roller bracket 5, is started. The output torque of the drive motor 8 is transmitted to the drive roller 7, causing the drive roller 7 to rotate at high speed. The rotating drive roller 7 generates friction with the surface of the steel drum plate. Under the action of friction, the plate is driven to move continuously towards the rolling area. At the same time, the hydraulic rod 4 applies a stable downward pressure to the drive roller bracket 5, so that the plate is tightly attached to the surface of the two "V"-shaped driven rollers 12. Through the active rotation of the drive roller 7 and the passive following rotation of the driven roller 12, a synergistic squeezing and rolling action is formed, so that the flat plate gradually bends within the triangular clamping space. During this process, the hydraulic rod 4 can finely adjust the pressure of the drive roller 7 in real time according to the degree of bending of the plate to ensure that the bending curvature of each part of the plate is uniform and consistent, and finally form a cylindrical steel drum body that meets the specifications, completing the rolling process.

[0051] Furthermore, through the sliding cooperation between the movable frame 9 and the base frame 1, this device can flexibly adjust the distance between the two V-shaped driven rollers 12 and the drive roller 7 on the second fixed support 10. Combined with the bolt fixing structure between the first auxiliary support frame 2 and the first positioning hole 23 on the movable frame 9, it achieves precise locking of the distance at multiple levels. Simultaneously, the hydraulic rod 4 inside the first fixed frame 3 can push the drive roller support 5 to move smoothly along the guide rod 6, finely adjusting the position of the drive roller 7. This allows the rolling space formed by the drive roller 7 and the driven roller 12 to adapt to the processing of various specifications of steel drums, from small to large diameters. Compared to existing equipment that requires replacing the entire rolling assembly, this device does not require disassembling core components; specification switching can be completed simply through mechanical adjustment. This not only reduces equipment investment costs but also shortens production changeover time, effectively improving the continuity and efficiency of multi-specification steel drum production.

[0052] In the auxiliary support assembly, the sliding fit between the second auxiliary support frame 13 and the connecting frame 16, and the rotational connection between the rotating shaft 15 and the second fixed frame 14, allow the first support roller 18 to be adjusted at multiple angles through the bolt fixing of the second positioning hole 24, which can accurately adapt to the feeding support requirements of steel drum plates of different specifications. The second support roller 20 arranged in a V-shape at the upper end of the base frame 1 can form a stable support for the middle of the plate, and together with the feeding end support of the first support roller 18, a multi-point collaborative support system is constructed, which effectively avoids the steel drum plates from shifting or wrinkling during the conveying and rolling process. At the same time, the limiting frame 25 on the base frame 1 forms a front and rear limit on the movable frame 9, ensuring that the driven roller 12 is stable in position during the rolling process. The drive roller 7 achieves smooth pressure through the cooperation of the hydraulic rod 4 and the guide rod 6, making the bending arc of the plate uniform and consistent, significantly improving the roundness accuracy and dimensional consistency of the steel drum body, and providing a guarantee for the high-quality development of subsequent welding, bottom sealing and other processes.

[0053] The movable frame 9 is constrained by the first slider 22, the first slide groove 21, and the limiting frame 25, ensuring a smooth and uninterrupted sliding process. With the bolt fixing method of the first positioning hole 23, the operator can quickly adjust and lock the position of the driven roller 12. After the connecting frame 16 adjusts the angle of the first support roller 18 by rotating the shaft 15, it can be firmly fixed by the second auxiliary support frame 13 and the second positioning hole 24 on the connecting frame 16. The adjustment logic is clear, the operation steps are simple, and no professional skills are required. The movement resistance of each core cooperating structure is small, the wear is slight, and the structure layout is compact and the force is reasonable, which can ensure long-term stable operation and reduce the frequency of equipment maintenance and operating costs.

[0054] Example 1: Automatic Angle Adjustment Structure The original installation reference of the second fixed bracket 14 is retained. The second drive motor 26 is fixedly installed on the upper end of the upper second fixed bracket 14 by means of a flange. The second drive motor 26 is a servo motor, model: SGMAH-05AAA41, which supports stepless speed regulation in both forward and reverse directions.

[0055] The surfaces of the two rotating shafts 15 are locked with the gears 27 by a flat key. The two gears 27 mesh horizontally. The output shaft of the second drive motor 26 is coaxially fixed with one of the rotating shafts 15 by a flexible coupling, forming a power transmission chain of "motor-gear-rotating shaft-connecting frame". The original second positioning hole 24 and bolt locking structure are retained.

[0056] The second drive motor 26 starts, and the gear 27 meshes and drives the two rotating shafts 15 to rotate synchronously in opposite directions. The connecting frame 16 rotates with the rotating shaft 15, adjusting the support range of the two first support rollers 18. The entire process does not require manual approach to the rolling area, improving the adjustment efficiency compared to manual operation. The support angle is precise, and there is no offset or wrinkles when rolling thick plates, reducing roundness error.

[0057] Example 2: Dual-guided positioning structure The original first auxiliary support frame 2 is milled, and two second slide grooves 28 are symmetrically opened at its upper end along the length direction.

[0058] The movable frame 9 retains the original first slider 22 and adds two second sliders 29. The second sliders 29 and the first slider 22 are vertically distributed vertically to form a "double guide structure".

[0059] The second slider 29 is made of polytetrafluoroethylene, with a rounded transition on the surface to reduce impact and friction during sliding.

[0060] The movable frame 9 moves to the right along the base frame 1; at this time, the first slider 22 slides along the first slide groove 21, and the second slider 29 slides synchronously along the second slide groove 28. The upper and lower double guides form a rigid constraint, which effectively offsets the lateral impact force on the movable frame 9 when the thick plate is rolled into a circle, reduces the distance accuracy error between the driven roller 12 and the driving roller 7, reduces the roundness error of the steel barrel body, and avoids elliptical defects caused by offset when guided by a single guide.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
