[0049] Specifically, the circular arc forming device comprises a rotating assembly 10, a limiting assembly 20 and a power assembly 30. The rotating assembly 10 comprises a limiting disc assembly, which is rotatably arranged. The limiting disc assembly is provided with a limiting portion 15, which is used for limiting the end of the workpiece 40 to be processed. A part of the limiting assembly 20 and the limiting disc assembly form a containing space for containing the workpiece 40 to be processed. The limiting assembly 20 is used for applying a pre-tightening force to the workpiece 40 to be processed towards the side of the limiting disc assembly. A part of the power assembly 30 is connected with the limiting assembly 20. The output end of the power assembly 30 is detachably connected with the limiting disc assembly. The power assembly 30 drives the limiting disc assembly to rotate, so as to drive the workpiece 40 to be processed to rotate by a preset angle along the circumferential direction of the limiting disc assembly.

[0050] In combination Figures 1 to 3 As shown, the rotating assembly 10 comprises a limiting disc assembly, which can be rotated by the driving of the power assembly. The limiting disc assembly is provided with a limiting portion 15, which is used for limiting the end of the workpiece 40 to be processed, so as to drive the workpiece 40 to be processed to rotate together with the limiting disc assembly, so as to perform the circular arc forming processing. The limiting assembly 20 is used in cooperation with the rotating assembly 10. It forms a containing space with the limiting disc assembly, which is used for placing the workpiece 40 to be processed. The main function of the limiting assembly 20 is to apply a pre-tightening force to the workpiece 40 to be processed, so as to ensure the stability and forming precision of the workpiece during the circular arc forming process. The power assembly 30 is a part for providing rotating power, which can be but is not limited to an electric motor, a hydraulic motor, a speed reducer, etc. The output end of the power assembly 30 is detachably connected with the limiting disc assembly, so that the power assembly 30 can be flexibly combined with or separated from the rotating assembly 10, which is convenient for maintenance and replacement. The power assembly 30 drives the limiting disc assembly to rotate. By controlling the rotating angle, the workpiece 40 to be processed can be accurately rotated to a preset angle along the circumferential direction of the limiting disc assembly, so as to complete the forming of the circular arc shape.

[0051] The technical scheme of the utility model discloses, the arc forming processing device passes through the cooperation of rotating assembly 10, limiting assembly 20 and power assembly 30, can efficiently, accurately arc forming processing is carried out to the workpiece to be processed, especially suitable for the occasion that high-precision arc forming is needed.Through detachable design and the pre-tightening force control of limiting assembly, the device has good adaptability and flexibility, can process workpieces of different shapes and sizes, while ensuring processing quality and efficiency.

[0052] Further, the rotating assembly 10 includes a bearing 12 and a support plate 13. The first end of the bearing 12 is connected to the output end of the power assembly 30, and the second end of the bearing 12 is detachably connected to the limiting disc assembly. The support plate 13 is connected to the bearing 12 and is disposed proximate to the second end of the bearing 12. The support plate 13 is connected to the limiting disc assembly. Through the cooperation of the bearing 12 and the support plate 13, not only can the rotation of the limiting disc assembly be effectively transmitted and ensured, but also the stability and accuracy during the entire rotation process can be ensured, which is crucial for the quality control of arc forming processing. In particular, the detachable design of the bearing 12 enables the device to adapt to workpiece processing of different sizes and shapes, enhancing the versatility and adaptability of the equipment. The provision of the support plate 13 further ensures the stability of the rotation process and reduces the forming errors caused by mechanical vibration.

[0053] In combination Figure 2 In this embodiment, the first end of the bearing 12 is connected to the output end of the power assembly 30, so that the rotational force output by the power assembly 30 is transmitted to the limiting disc assembly through the bearing 12. The second end of the bearing 12 is detachably connected to the limiting disc assembly, which provides flexibility and facilitates the replacement of limiting disc assemblies of different specifications under different processing requirements, as well as maintenance and component replacement. The support plate 13 provides stable support for the bearing 12 and the limiting disc assembly and ensures their stability and accuracy during rotation. The support plate 13 is disposed proximate to the second end of the bearing 12, is connected (welded) to the bearing 12, and is connected to the limiting disc assembly. This structural arrangement ensures that the limiting disc assembly remains stable during rotation, reduces vibration and displacement caused by high-speed rotation, and thus improves processing accuracy.

[0054] Further, the limiting disc assembly includes a limiting disc 11, a rotating disc 14, and a limiting part 15. The limiting disc 11 is detachably connected with the second end of the bearing 12, and there are multiple limiting discs 11 with different radii. The rotating disc 14 is connected with the support plate 13 and is arranged between the support plate 13 and the limiting disc 11. The limiting part 15 is connected with the rotating disc 14. Part of the limiting assembly 20, the limiting disc 11, and part of the rotating disc 14 form a containing space. This arrangement not only considers the positioning and support of the workpiece 40 during the arc forming process, but also enhances the versatility and adaptability of the equipment by detachable limiting disc 11 and rotating disc 14, so that different sizes and shapes of arc workpieces can be efficiently and accurately processed.

[0055] In combination Figure 2 and Figure 3 , the limiting disc 11 is detachably connected with the second end of the bearing 12, which allows different specifications of limiting discs 11 to be replaced according to different processing needs (such as the size and shape of the workpiece). There are multiple limiting discs 11 with different radii, which allows the equipment to process arc workpieces with different radii of curvature, improving the flexibility and adaptability of the device. The rotating disc 14 is connected with the support plate 13 and is located between the support plate 13 and the limiting disc 11. Its main function is to transmit stable support and power from the support plate 13 to the limiting disc 11. The limiting part 15 is connected with the rotating disc 14, and the limiting part 15 is used to limit the end of the workpiece 40 to be processed, so that the workpiece 40 to be processed can rotate with the limiting disc assembly to perform arc forming processing. In addition, the limiting part 15 also plays a guiding and supporting role. When the limiting disc assembly rotates, the limiting part 15 guides the workpiece 40 to be processed to rotate along the preset path, while providing the necessary support force to ensure the safety and accuracy of the workpiece during high-speed rotation and forming. In the rotating assembly 10, part of the limiting assembly 20, the limiting disc 11, and part of the rotating disc 14 form a containing space, which is the working position of the workpiece 40 to be processed during processing. The workpiece 40 to be processed is pre-tightened by the limiting assembly 20 and positioned in this space. When the rotating disc 14 and the limiting disc 11 are rotated under the drive of the power assembly 30, the workpiece 40 to be processed is guided by the limiting part 15 and supported by the limiting disc 11, and forms the required arc shape along the preset path.

[0056] Further, the limiting assembly 20 comprises a base 21 and a limiting piece 22. The base 21 is provided with a receiving cavity, and at least part of the power assembly 30 is arranged in the receiving cavity. The limiting piece 22 is connected with the base 21, and the limiting piece 22, the limiting disc 11 and part of the rotating disc 14 form a receiving space. In this way, the space layout is fully utilized, the compactness of the device structure and the integration of functions are realized, and the operation convenience and the maintenance of the components are also considered. In actual application, the arrangement of the limiting assembly 20 ensures that the arc forming machining device can efficiently, accurately and safely complete the designed functions.

[0057] In the embodiment, the base 21 is the basic part of the limiting assembly 20, which provides stable support for the entire device. The base 21 is internally provided with a receiving cavity, so as to arrange at least part of the power assembly 30 therein, realizing the compactness and modularity of the device structure. Arranging the power assembly 30 in the receiving cavity of the base 21 not only saves space, but also better protects the power assembly 30, reduces the influence of external interference on the work of the power assembly 30, and facilitates the maintenance and replacement of the power assembly 30. The limiting piece 22 is connected with the base 21 and is used for directly contacting and acting on part of the workpiece 40 to be machined. The limiting piece 22, the limiting disc 11 and the rotating disc 14 form a receiving space, which is the specific position of the workpiece 40 to be machined in the machining process. Through the cooperation of the base 21 and the limiting piece 22, the limiting assembly 20 not only provides fixed support for the workpiece 40 to be machined during machining, but also forms a complete workpiece forming environment with the limiting disc 11 and the rotating disc 14 in the rotating assembly 10. The workpiece 40 to be machined is fixed in the receiving space by the limiting assembly 20 and the rotating assembly 10, and as the limiting disc assembly rotates, the workpiece 40 to be machined completes the arc forming process under the action of the limiting part 15, while the power assembly 30 is hidden in the receiving cavity of the base 21, which not only ensures the neat appearance of the device, but also realizes the effective transmission of power.

[0058] Further, the limiting piece 22 comprises a connecting plate 221 and a limiting rod 222. The connecting plate 221 is connected with the base 21, and the length direction of the connecting plate 221 is arranged in parallel with the axial direction of the limiting disc 11. The limiting rod 222 is connected with the connecting plate 221, and the length direction of the limiting rod 222 is arranged perpendicular to the axial direction of the limiting disc 11. An end of the limiting rod 222 away from the connecting plate 221 and part of the rotating disc 14 form a receiving space. Through the parallel connection of the connecting plate 221 with the base 21 and the perpendicular connection of the limiting rod 222 with the connecting plate 221, a stable and accurate workpiece limiting structure is formed, which not only ensures the stability of the workpiece in the machining process, but also realizes the efficient arc forming of the workpiece.

[0059] In combination with Figure 1 , Figure 3As shown, one end of the connecting plate 221 is firmly connected with the base 21, and the length direction thereof is arranged in parallel with the axial direction of the limiting disc 11, so as to ensure that the connecting plate 221 can remain in a stable state when the limiting disc 11 rotates, and to provide a stable connecting platform for the limiting rod 222. The limiting rod 222 is connected with the other end of the connecting plate 221, and the length direction thereof is arranged in perpendicular to the axial direction of the limiting disc 11, so that the limiting rod 222 can directly act on the side surface of the workpiece 40 to be processed, and apply a pre-tightening force perpendicular to the rotation axis, thereby ensuring the stability and positioning accuracy of the workpiece 40 to be processed during the rotation forming process. The end of the limiting rod 222 away from the connecting plate 221, together with the part of the structure between the limiting disc 11 and the rotating disc 14, forms an accommodating space, which is the position of the workpiece 40 to be processed when the workpiece 40 to be processed is processed. The workpiece 40 to be processed is placed on the rotating disc 14, one side of the workpiece 40 to be processed is attached to the limiting disc 11, and the other side is limited by the limiting rod 222. The side of the workpiece 40 to be processed attached to the limiting disc 11 rotates in this space together with the limiting disc assembly, and the arc forming process is completed.

[0060] Further, the limiting member 22 includes a limiting plate connected with the end of the limiting rod 222 away from the connecting plate 221, and the length direction of the limiting plate is arranged in parallel with the axial direction of the limiting disc 11, and the limiting plate, the limiting disc 11 and part of the rotating disc 14 form an accommodating space; wherein the height of the limiting plate is greater than or equal to the height of the limiting disc 11. In this embodiment, the limiting plate is fixedly connected with the limiting rod 222, so as to adapt to workpieces 40 to be processed of different heights or thicknesses, and to ensure that the entire side surface of the workpiece is limited, and to effectively avoid deformation or displacement of the workpiece during the forming process due to the upper part of the workpiece not being limited, thereby improving the accuracy of arc forming and the qualification rate of finished products.

[0061] Further, the connecting plate 221 is detachably connected with the base 21. The detachable connection between the connecting plate 221 and the base 21 can be achieved in various ways, such as using bolts, pins, buckles or quick connectors, etc. These connection methods need to ensure the stability of the connection and the convenience of disassembly. When workpieces of different sizes or shapes need to be processed, the appropriate length of the connecting plate 221 can be replaced to match the position of the new limiting rod 222 or limiting plate, so as to ensure the accuracy of workpiece limiting and supporting. In addition, when the connecting plate 221 is damaged or used for a long time, the detachable design allows it to be quickly replaced, reduces the production interruption caused by equipment downtime for maintenance, and improves the operation efficiency of the equipment.

[0062] Further, the limiting rod 222 is movably connected with the connecting plate 221. By adjusting the position of the limiting rod 222, the operator can easily change the position of the contact point of the limiting rod 222 with the workpiece, which is very helpful for adjusting the limiting force and positioning accuracy of the workpiece during the machining process. In different machining stages, this adjustability can significantly improve the machining efficiency and the forming quality of the workpiece.

[0063] Further, in combination with Figure 4 As shown, the limiting rod 222 includes a reinforcing rib 223, one end of the reinforcing rib 223 is connected with the connecting plate 221, and the other end of the reinforcing rib 223 is connected with the limiting rod 222. The addition of the reinforcing rib 223 significantly enhances the overall structural strength of the limiting rod 222, so that it can remain stable and not deformed when bearing a larger limiting force and extrusion force, ensuring the accuracy and stability during the machining process. In addition, the reinforcing rib 223 can improve the force distribution of the limiting rod 222 when bearing force, so that the force is more evenly transmitted to the connecting plate 221, avoiding local stress concentration, reducing the wear and damage of the connecting plate and the connecting part of the limiting rod, and prolonging the service life of the equipment. The connection mode of the reinforcing rib 223 with the connecting plate 221 and the limiting rod 222 can be but not limited to bolt fixing or welded joint design, so that the damaged reinforcing rib can be quickly replaced during equipment maintenance, or the position and angle of the reinforcing rib can be adjusted according to the machining requirements to optimize the limiting effect.

[0064] Further, the base 21 includes a base body 211, a support leg 212, a longitudinal beam 213 and a cross beam 214, the base body 211 has a receiving cavity, the connecting plate 221 is connected with the base body 211; the support leg 212 is connected with the base body 211; one of the two adjacent support legs 212 located on the first side of the base body 211 is connected with the other through the longitudinal beam 213, and one of the two adjacent support legs 212 located on the second side of the base body 211 is connected with the other through the longitudinal beam 213, wherein the first side of the base body 211 is arranged opposite to the second side of the base body 211; one of the two longitudinal beams 213 is connected with the other through the cross beam 214. Such arrangement not only provides stable support required for the operation of the device, but also optimizes the layout and connection mode of the components, so that the entire device is not only structurally strong, but also easy to maintain and adjust.

[0065] In combination with Figure 4 and Figure 5As shown, the base body 211 is internally designed with a receiving cavity for accommodating the power assembly 30, thereby realizing compactness and modularity of the device structure. The connection of the connecting plate 221 with the base body 211 ensures the mounting stability and operation accuracy of components such as the limiting rod 222. The feet 212 are connected with the base body 211 for providing external support and stability. The design of the feet 212 takes into account the load-bearing capacity and stability of the equipment. One of the two adjacent feet 212 located on the first side of the base body 211 is connected with the other through a longitudinal beam 213, and similarly, the two adjacent feet 212 located on the second side of the base body 211 are also connected through a longitudinal beam 213, wherein the first side and the second side are oppositely arranged, and such an arrangement forms an external frame structure of the base 21, enhancing the overall rigidity and stability of the base. At the same time, one of the two longitudinal beams 213 is connected with the other through a cross beam 214, and such a reinforcing measure further stabilizes the structure of the base, improving the anti-vibration performance and stability of the equipment during the machining process.

[0066] Further, the base body 211 is connected with the reinforcing plate through a groove-shaped member, forming a more stable support structure, ensuring that the connection part will not be deformed or broken when bearing the machining load, increasing the load-bearing capacity and bending resistance of the base, and improving the machining precision and efficiency of the device.

[0067] Further, the base 21 includes a top plate, and the connecting plate 221 is connected with the base body 211 through the top plate. The design of the top plate ensures that the connection between the connecting plate 221 and the base is more stable. The planar structure of the top plate provides sufficient contact area for the connecting plate 221, which can effectively transmit force through bolt fixation or welding, etc., to ensure the stable operation of the limiting rod 222 during the machining process.

[0068] Further, the power assembly 30 includes a speed reducer 31 and a distribution box 32, the speed reducer 31 is arranged in the receiving cavity; and the distribution box 32 is electrically connected with the speed reducer 31. The independent modular design of the speed reducer 31 and the distribution box 32 makes it unnecessary to disassemble the entire equipment for replacement or upgrading of any part, reducing the maintenance cost and downtime. At the same time, the arrangement of the receiving cavity also provides sufficient space for possible future upgrading or maintenance, facilitating the maintenance and part replacement by the operator. The precise design and reasonable layout of the power assembly 30 provide stable and reliable power and electrical control for the multifunctional arc forming equipment, which is the key to ensuring the efficient operation and machining precision of the equipment.

[0071] 2) The structural design of the limiting rod 222 and the reinforcing rib 223, and the accommodation space formed between the end of the limiting rod 222, the limiting disc 11 and the rotating disc 14, ensure the accurate limiting of the workpiece during machining, improving the accuracy of circular arc forming. At the same time, by controlling the relative position of the limiting rod 222, the flatness of the circular arc piece is effectively regulated, achieving the purpose of improving the consistency of the processed products.

[0072] 3) The device simplifies the traditional circular arc forming process, reduces the dependence on high-cost numerical control machine tools, and reduces the processing cost.
