Description

Technical Field

[0001] This utility model relates to equipment for rolling sheet metal into circles. Background Technology

[0002] In existing sheet metal rolling forming equipment, the sheet metal is typically rolled using a combination of multiple sets of active and driven wheels, including shaping, fixed, and forming wheels. While this method can achieve the rolling process from flat to curved sheets, in practical applications, especially when the sheet metal is thick or has a large curvature variation, uneven stress often occurs in the bending area. Since the rolling process mainly relies on wheel clamping and conveying, when the sheet metal lacks effective support in the middle section (between the rolling radius moving wheel assembly and the rolling shaping wheel assembly), phenomena such as material springback, localized dents, or roundness deviations after forming can easily occur, thus affecting the geometric accuracy and surface quality of the product.

[0003] Traditional equipment often compensates for insufficient support by increasing the clamping force of the roller assembly or increasing the bending speed. However, this method not only exacerbates stress concentration in the sheet metal, leading to material fatigue deformation, but also easily causes accelerated roller wear, increased energy consumption, and shortened equipment lifespan. In addition, for thin plates or highly elastic metal materials, relying solely on the clamping of the rolling roller assembly cannot effectively control the amount of springback, resulting in poor product consistency and requiring multiple adjustments later, which seriously affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a sheet metal rolling forming device that achieves flexible support for the outer arc of the sheet metal by lifting or sliding adjustment through an auxiliary support wheel assembly, effectively suppressing the springback and twisting of the sheet metal during the rolling process.

[0005] The purpose of this utility model is achieved as follows: A sheet metal rolling forming device includes a frame, a motor, a first reducer, a second reducer, a shaping and conveying wheel assembly for sucking in and shaping the sheet metal, a rolling fixed wheel assembly for shaping and providing power to the sheet metal, a rolling radius moving wheel assembly for rolling, flattening and fixing the arc shape of the sheet metal, a rolling shaping wheel assembly for adjusting the radius and profile of the sheet metal, and an auxiliary support wheel assembly for providing reinforcement support to the sheet metal. The shaping and conveying wheel assembly, the rolling fixed wheel assembly, the rolling radius moving wheel assembly, and the rolling shaping wheel assembly are arranged sequentially on the frame, and the auxiliary support wheel assembly is disposed between the rolling radius moving wheel assembly and the rolling shaping wheel assembly. The input end of the first reducer is connected to the output shaft of the motor, and the output end of the first reducer is connected to the shaping and conveying wheel assembly and the rolling fixed wheel assembly respectively. The input end of the second reducer is connected to the shaping and conveying wheel assembly or the rolling fixed wheel assembly, and the output end of the second reducer is connected to the rolling radius moving wheel assembly and the rolling shaping wheel assembly respectively. The shaping and conveying wheel assembly is provided with a first conveying channel for conveying the sheet material; The rolling fixed roller assembly is provided with a second conveying channel for conveying the sheet material; The rolling radius moving wheel assembly is provided with a third conveying channel for conveying the sheet material; The rolling and shaping wheel assembly is provided with a fourth conveying channel for conveying the sheet material; The position of the auxiliary support wheel assembly is adjustable.

[0006] By adding an adjustable auxiliary support wheel assembly to the existing forming and conveying wheel assembly, rolling fixed wheel assembly, rolling radius moving wheel assembly, and rolling forming wheel assembly, and placing it between the rolling radius moving wheel assembly and the rolling forming wheel assembly, an additional support is provided for the outer arc portion during the sheet metal rolling process. This structural design effectively disperses concentrated stress in the sheet metal during bending, preventing springback, twisting, or denting caused by uneven stress, significantly improving the roundness and surface flatness of the formed product. Simultaneously, the adjustable structure of the auxiliary support wheel assembly allows for flexible adjustment of the support position and force according to different sheet metal thicknesses, curvatures, and forming diameters, achieving compatible rolling of multiple product specifications. The overall structural design is reasonable, the rolling process is stable, and the product forming consistency is high, improving both production accuracy and stability, and extending the service life of the equipment.

[0007] The objective of this utility model can also be achieved by the following technical measures: Furthermore, it also includes a first lifting assembly. The shaping and conveying wheel assembly includes a first driving wheel and a first driven wheel, which are positioned opposite each other, one above the other, forming the first conveying channel. The first driving wheel is connected to the output end of the first reducer. The frame is provided with a first limiting groove. The end of the first driven wheel is slidably disposed in the first limiting groove. The first lifting assembly is disposed on the frame and is provided with a height-adjustable first lifting part. The first lifting part extends into the first limiting groove and abuts against the end of the first driven wheel, thereby adjusting the position of the first driven wheel and thus adjusting the gap of the first conveying channel. The first limiting groove restricts the movement distance of the first driven wheel.

[0008] By incorporating a first lifting component and a first limiting groove structure, the first driven wheel in the shaping and conveying wheel assembly can slide up and down within the limiting groove, and is precisely adjusted by the height-adjustable first lifting part, thereby achieving rapid and controllable adjustment of the gap in the first conveying channel. This design effectively solves the problems of fixed conveying wheel spacing and inconvenient adjustment in traditional equipment. The clamping force can be flexibly set according to the thickness, hardness, and material differences of the sheet material, ensuring uniform force and smooth conveying during the suction and shaping process, preventing slippage or deviation. Simultaneously, the limiting groove's constraint on the driven wheel's movement range ensures structural stability and repeatability, improving the overall machine's adjustment efficiency and forming consistency.

[0009] Furthermore, it also includes a second lifting assembly. The rolling fixed wheel assembly includes a second driving wheel and a second driven wheel, which are positioned opposite each other, one above the other, forming the second conveying channel. One end of the second driving wheel is connected to the output end of the first reducer, and the other end is connected to the input end of the second reducer. The frame is provided with a second limiting groove, and the end of the second driven wheel is slidably disposed in the second limiting groove. The second lifting assembly is provided with a height-adjustable second lifting part, which extends into the second limiting groove and abuts against the end of the second driven wheel, thereby adjusting the position of the second driven wheel and thus adjusting the gap of the second conveying channel. The second limiting groove restricts the movement distance of the second driven wheel.

[0010] By incorporating a second lifting component and a second limiting groove structure, the second driven wheel in the rolling fixed wheel assembly can achieve controllable sliding within the limiting groove. Its position can be precisely adjusted via a height-adjustable second lifting unit, thereby enabling rapid adjustment of the gap in the second conveying channel. This design allows for flexible setting of the inter-wheel pressure according to different sheet thicknesses and rolling requirements, ensuring a tight fit between the sheet and the fixed wheel during the rolling and shaping stage, guaranteeing shaping accuracy and transmission stability. Simultaneously, the limiting groove's constraint on the driven wheel's movement range improves structural positioning reliability, avoiding molding defects caused by excessive compression or loosening, thus enhancing the stability of the rolling process and product consistency.

[0011] Furthermore, it also includes a third lifting assembly. The frame is provided with a third limiting groove. The end of the rolling radius moving wheel assembly is slidably disposed in the third limiting groove. The rolling radius moving wheel assembly includes a third driving wheel and a third driven wheel, which are positioned opposite each other, one above the other, forming the third conveying channel. The third driving wheel is connected to the output end of the second reducer. The third lifting assembly is provided with a height-adjustable third lifting part. The third lifting part extends into the third limiting groove and abuts against the rolling radius moving wheel assembly, thereby adjusting the position of the rolling radius moving wheel assembly. The third limiting groove restricts the movement distance of the rolling radius moving wheel assembly.

[0012] By incorporating a third lifting component and a third limiting groove structure, the rolling radius moving wheel assembly can achieve smooth and controllable sliding adjustment on the frame. Its position is precisely controlled by the height-adjustable third lifting unit, enabling flexible adjustment of the rolling radius moving wheel assembly's position. This design allows for precise setting of the moving wheel assembly's position based on different sheet thicknesses, materials, or target curvatures, resulting in a more reasonable contact angle and forming trajectory during the rolling process, ensuring stable rolling and consistent roundness. The third limiting groove effectively limits the moving wheel assembly's movement range, preventing structural displacement caused by over-adjustment, improving the accuracy of position adjustment and the stability of equipment operation, thereby guaranteeing the accuracy of rolling and the quality of the product.

[0013] Furthermore, it also includes a lower end seat and a connecting plate. The third driven wheel is rotatably disposed in the lower end seat. The ends of the third driving wheel are respectively connected to the corresponding upper end plates. The upper end plates are located above the lower end seat. The side walls of the upper end plates and the lower end seat are respectively connected to the connecting plate. The third lifting part abuts against the lower end seat. Move the position of the upper end plate or the lower end seat and lock the connecting plate to adjust the distance between the third driving wheel and the third driven wheel, thereby adjusting the gap of the third conveying channel; The third lifting section pushes the lower end seat, thereby moving the rolling radius moving wheel assembly and adjusting its position.

[0014] By setting up a combined structure of a lower end seat, an upper end plate, and a connecting plate, the relative position between the third driving wheel and the third driven wheel can be precisely adjusted by moving and locking the connecting plate, thereby flexibly controlling the gap of the third conveying channel. Simultaneously, the third lifting section can push the lower end seat to fine-tune the overall position of the rolling radius driving wheel assembly, achieving dual adjustment of the position of the rolling radius driving wheel assembly and the gap of the third conveying channel. This design allows for flexible setting of the wheel spacing and position according to different sheet thicknesses, materials, and target curvatures, ensuring uniform stress and stable curvature formation during the rolling process. The rigid fit between the lower end seat and the upper end plate enhances structural strength and vibration resistance, avoiding dimensional errors caused by loosening or misalignment, thus achieving a high-precision and high-stability rolling forming effect.

[0015] Furthermore, it also includes a fourth lifting assembly. The frame is provided with a fourth limiting groove. The end of the rounding and shaping wheel assembly is slidably disposed in the fourth limiting groove. The rounding and shaping wheel assembly includes a fourth driving wheel and a fourth driven wheel. The fourth driving wheel and the fourth driven wheel stand opposite each other, one above the other, forming the fourth conveying channel between them. The fourth driving wheel is connected to the output end of the second reducer. The fourth lifting assembly is provided with a height-adjustable fourth lifting part. The fourth lifting part extends into the fourth limiting groove and abuts against the rounding and shaping wheel assembly, thereby adjusting the position of the rounding and shaping wheel assembly. The fourth limiting groove restricts the movement distance of the rounding and shaping wheel assembly.

[0016] By incorporating a fourth lifting component and a fourth limiting groove structure, the rolling and shaping wheel assembly can achieve smooth and controllable sliding adjustment on the frame. Its position is precisely controlled by the height-adjustable fourth lifting unit, enabling flexible adjustment of the shaping wheel assembly's position. This design allows for precise positioning and shaping of the rolled sheet material according to its thickness, material, and target curvature, ensuring stable roundness and consistent structure. The fourth limiting groove effectively constrains the movement range of the shaping wheel assembly, preventing offset or interference caused by over-adjustment, improving the accuracy of position adjustment and the stability of the mechanism's operation, thereby guaranteeing the precision of the rolling process and the consistency of the product's appearance.

[0017] Furthermore, it also includes a fifth lifting assembly. The frame is provided with a fifth limiting groove. The end of the auxiliary support wheel assembly is slidably disposed in the fifth limiting groove. The auxiliary support wheel assembly includes a fifth driven wheel. A pressing area is formed between the third conveying channel and the fourth conveying channel. The fifth driven wheel faces the pressing area. The fifth lifting assembly is provided with a height-adjustable fifth lifting part. The fifth lifting part abuts against the end of the auxiliary support wheel assembly, thereby adjusting the movement position of the auxiliary support wheel assembly toward the pressing area. The fifth limiting groove restricts the movement distance of the auxiliary support wheel assembly.

[0018] By incorporating a fifth lifting component and a fifth limiting groove structure, the auxiliary support wheel assembly can slide smoothly on the frame. Its movement towards the pressing area is precisely controlled by the height-adjustable fifth lifting section, allowing for flexible adjustment of the auxiliary support wheel assembly's position. This design can precisely adjust the contact pressure between the auxiliary support wheel and the sheet material according to different sheet thicknesses, materials, and rolling radii, enhancing support during the rolling process and preventing sagging, springback, or deformation. The fifth limiting groove constrains the movement range of the support wheel assembly, ensuring a stable and safe adjustment process, improving adjustment repeatability and equipment reliability, thereby further enhancing the stability of rolling and the quality of the finished product.

[0019] Furthermore, the center distance between the fixed roller assembly and the moving roller assembly is less than 170mm.

[0020] By designing the center distance between the second driving wheel of the rolling fixed wheel assembly and the third driving wheel of the rolling radius moving wheel assembly to be less than 170mm, the two wheel sets maintain a small center distance during the rolling process, thereby enhancing the structural rigidity and stress coordination between adjacent wheel sets. This design effectively reduces the suspended length of the sheet material during transmission, improves the continuity of support for the sheet material, and prevents material sagging, deformation, or uneven curvature caused by excessive spacing. Simultaneously, the smaller center distance helps improve the smoothness and forming accuracy of the rolling transition, resulting in more uniform stress on the sheet material during bending, thus achieving a rolling forming effect with higher roundness and better surface quality.

[0021] Furthermore, the diameter of the rolled sheet is in the range of 700mm-1100mm.

[0022] By designing the sheet metal rolling diameter range to 700mm to 1100mm, the equipment can cover the forming needs of common medium and large-sized circular components (such as automotive spare tire covers, cylindrical shells, decorative covers, etc.). This range design balances structural strength and adjustment flexibility, ensuring bending stability when rolling small diameters while maintaining good forming accuracy when rolling large diameters. Through rapid adjustment within this diameter range, the equipment can adapt to the production of products of different specifications, significantly improving the versatility and adaptability of the rolling equipment, reducing mold change and adjustment time, thereby increasing production efficiency and reducing manufacturing costs.

[0023] The beneficial effects of this utility model are as follows: This invention adds an adjustable auxiliary support wheel assembly to the existing forming and conveying wheel assembly, rolling fixed wheel assembly, rolling radius moving wheel assembly, and rolling forming wheel assembly. This auxiliary support wheel assembly is positioned between the rolling radius moving wheel assembly and the rolling forming wheel assembly, providing additional support to the outer arc portion during sheet metal rolling. This structural design effectively disperses concentrated stress on the sheet metal during bending, preventing springback, twisting, or denting caused by uneven stress, significantly improving the roundness and surface flatness of the formed product. Simultaneously, the adjustable structure of the auxiliary support wheel assembly allows for flexible adjustment of the support position and force according to different sheet metal thicknesses, curvatures, and forming diameters, enabling compatible rolling of multiple product specifications. The overall structural design is reasonable, the rolling process is stable, and product forming consistency is high, improving production accuracy and stability while extending the equipment's service life.

[0045] Furthermore, the diameter of the 600 rolled sheet ranges from 700mm to 1100mm.

[0046] Manual adjustment method: Adjustment of the shaping and conveying wheel assembly 2: By operating the first lifting assembly 100, the first lifting part 1000 is raised and lowered, thereby driving the first driven wheel 23 to slide up and down along the first limiting groove 101, adjusting the gap of the first conveying channel 21. The operator can adjust the clamping force according to the thickness of the plate 600, so that the plate 600 can be smoothly sucked in without slipping, ensuring stable conveying.

[0047] Adjustment of the rolling fixed wheel assembly 3: By operating the second lifting assembly 200, the second driven wheel 33 is moved within the second limiting groove 102, changing the gap of the second conveying channel 31. This adjustment is used to control the degree of compression of the sheet 600 during the shaping stage, ensuring that the sheet 600 is stably bonded to the wheel mold in the initial stage of rolling, providing a foundation for subsequent forming.

[0048] Adjustment of the rolling radius moving wheel assembly 4: By operating the third lifting assembly 300 to change the height of the third lifting part 301, the rolling radius moving wheel assembly 4 can be driven to slide smoothly along the third limiting groove 103, thereby achieving precise adjustment of the position of the rolling radius moving wheel assembly 4. This adjustment can change the relative position of the assembly according to the required rolling diameter to achieve forming control of different curvatures. In addition, by moving the position of the upper end plate 9 or the lower end seat 7 and locking the connecting plate 8, the distance between the third driving wheel 42 and the third driven wheel 43 can be precisely adjusted, thereby adjusting the gap of the third conveying channel 41. This operation can set a reasonable calendering spacing according to the thickness and hardness of the sheet 600, ensuring that the sheet 600 is subjected to uniform force, stable curvature, and consistent roundness during the rolling process. Overall, the rolling radius moving wheel assembly 4 can simultaneously achieve dual adjustment of position and channel gap, which is simple to operate and precise in positioning, helping to improve the rolling forming accuracy and product consistency.

[0049] Adjustment of the rolling and shaping wheel assembly 5: By operating the fourth lifting assembly 400, the fourth lifting part 401 is raised or lowered, thereby driving the rolling and shaping wheel assembly 5 to slide within the fourth limiting groove 104, thus adjusting the position of the rolling and shaping wheel assembly 5. This adjustment is mainly used for fine-tuning the curvature of the forming end and trimming the surface, ensuring that the roundness of the rolled plate 600 is consistent and the surface is flat.

[0050] Adjustment of the auxiliary support wheel assembly 6: By operating the fifth lifting assembly 500, the fifth lifting part 501 is adjusted, causing the auxiliary support wheel assembly 6 to move along the fifth limiting groove 105 and adjust its position toward the pressing area 106. This adjustment can set an appropriate support force according to the curvature and thickness of the sheet 600, providing additional support for the rolling process and preventing the sheet 600 from springing back or deforming.

[0051] The above manual adjustment allows operators to gradually fine-tune the position of each wheel group and the channel gap by referring to the scale markings and the results of the molding sample. After the adjustment is completed, each component is locked to ensure that the rolling process is stable and the force is uniform, so as to achieve a high-precision molding effect.

[0052] Advantages of synchronous drive: This invention employs a single motor 20 coupled with a first reducer 30 and a second reducer 1 to achieve synchronous drive of the forming and conveying wheel assembly 2, the rolling fixed wheel assembly 3, the rolling radius moving wheel assembly 4, and the rolling forming wheel assembly 5. This design significantly simplifies the power system structure, avoids the synchronization errors and control complexity caused by multi-motor 20 drives, and ensures coordinated operation and consistent linear speed of each wheel assembly, thereby improving the stability and precision of rolling forming. Simultaneously, the single motor 20 drive combined with multi-stage reduction transmission not only effectively improves transmission efficiency and torque output but also reduces equipment energy consumption and maintenance costs. The structure is more compact, installation and debugging are more convenient, and overall operational reliability is high, making it suitable for continuous, high-precision 600mm rolling production of sheet metal.

[0053] Working principle of the 600 sheet metal roll forming machine: When the sheet metal 600 roll forming equipment of the present invention is working, the output power of the motor 20 is transmitted to each group of drive wheels through the first reducer 30 and the second reducer 1, thereby realizing the synchronous drive of the shaping and conveying wheel assembly 2, the roll fixed wheel assembly 3, the roll radius moving wheel assembly 4, and the roll shaping wheel assembly 5.

[0054] After the sheet material 600 is formed by roll pressing in the previous process, it is sucked into the shaping and conveying wheel assembly 2 and first undergoes preliminary shaping through the adjustable first conveying channel 21 between the upper and lower wheels to ensure that the sheet material 600 enters the equipment smoothly and remains flat.

[0055] Subsequently, the sheet material 600 passes through the rolling fixed wheel assembly 3, the rolling radius moving wheel assembly 4, and the rolling shaping wheel assembly 5 in sequence. The gap and position of each wheel assembly can be precisely adjusted by independently set lifting components, thereby realizing segmented control of the bending arc of the sheet material 600.

[0056] The fixed roller assembly 3 is used for the initial shaping of the sheet 600 and provides power transmission. The rolling radius moving roller assembly 4 controls the rolling radius of the sheet 600 by adjusting its position to form the target arc. The rolling shaping roller assembly 5 performs arc finishing and roundness shaping on the formed sheet 600 to ensure the product's shape accuracy and surface flatness.

[0057] The auxiliary support wheel assembly 6 is positioned between the rolling radius moving wheel assembly 4 and the rolling shaping wheel assembly 5. It provides adaptive support through lifting adjustment to prevent springback and deformation of the sheet 600 during the rolling process.

[0058] Through the synergistic effect of the aforementioned multi-wheel group, the sheet metal 600 can achieve high-precision rolling and forming within a diameter range of 700mm to 1100mm, completing the continuous and automated production of circular shell-type components.

[0059] Example of producing car spare tire covers using a 600 sheet metal roll forming machine: Taking the production of automotive spare tire covers as an example, steel plates formed by roll forming are selected as raw materials. The plate 600 is designed to be 1.5mm thick, with an actual thickness of 1.4mm and a width of 300mm. The plate 600 is placed in the plate 600 rolling forming equipment of this invention. By adjusting the gap of the first conveying channel 21 of the shaping and conveying wheel assembly 2 to 1.45mm, the plate 600 is stably sucked in and initially shaped. Subsequently, the second conveying channel 31 of the rolling fixed wheel assembly 3 is set to 1.43mm to achieve initial shaping. The rolling radius moving wheel assembly 4 is adjusted to a predetermined position by the third lifting assembly 300 to make its rolling radius R=400mm, forming the required arc. The rolling shaping wheel assembly 5 is then finely adjusted to ensure that the forming roundness accuracy is within ±0.5mm. The auxiliary support wheel assembly 6 is adjusted 2mm toward the pressing area 106 to provide outer arc support for the plate 600 and prevent forming springback. After multiple rounds of collaborative rolling and shaping, the sheet material 600 is rolled into a circular shell with a diameter of approximately 800mm and a roundness deviation of less than 0.8mm, ultimately obtaining a high-precision circular shell that meets the installation requirements of the spare tire cover at the rear of the car.

[0060] Working principle (taking the production of car spare tire covers as an example): The sheet material 600 (designed thickness 1.5mm, actual thickness 1.4mm) formed by roll forming in the previous process enters the shaping and conveying wheel assembly 2 of this invention after being fed into the machine.

[0061] After the equipment is started, the output of motor 20 drives the shaping and conveying wheel assembly 2 and the rolling fixed wheel assembly 3 through the first reducer 30, and at the same time drives the rolling radius moving wheel assembly 4 and the rolling shaping wheel assembly 5 through the second reducer 1, so that each wheel group can operate synchronously.

[0062] The sheet material 600 is first pressed and initially shaped in the shaping and conveying wheel assembly 2 to ensure flatness and stable conveying. After entering the rolling fixed wheel assembly 3, it is initially shaped through adjustable gap. Then, at the rolling radius moving wheel assembly 4, the assembly position is adjusted to form a reasonable entry angle, so that the sheet material 600 has a speed difference between the inner and outer diameters, and is gradually rolled into an arc shape. Then, it passes through the rolling shaping wheel assembly 5 to refine the radius and shape of the sheet material 600 to ensure that the curvature and roundness are consistent.

[0063] The auxiliary support wheel assembly 6 is located between the rolling radius moving wheel assembly 4 and the rolling shaping wheel assembly 5. Its position toward the pressing area 106 is adjusted by the lifting assembly to provide support for the outer arc of the plate 600 and prevent springback and deformation.

[0064] After the product is rolled into a circle, its diameter is inspected upon discharge. If there is a deviation, it can be corrected by finely adjusting the clamping force of the rolling radius moving wheel assembly 4 and the rolling shaping wheel assembly 5.

[0065] This process enables continuous automated operation of sheet metal 600 from shaping, setting, rolling to finishing, ultimately obtaining a high-precision circular shell that meets the structural requirements of automotive spare tire covers.
