[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 5 As shown, a multi-dimensional profile bending machine includes: a machine table 100 for providing structural support and installation space; a first bending mechanism, including a front pressure roller 1, a left pressure roller 2 and a right pressure roller 3 distributed in a triangular shape on the upper end surface of the machine table 100, the front pressure roller 1 can be connected to the machine table 100 for forward and backward displacement, and the left pressure roller 2 and the right pressure roller 3 can be connected to the machine table 100 for left and right displacement respectively; a second bending mechanism, including a support ring seat 4 and a knob disk 5, the support ring seat 4 is connected to the machine table 100 in an adjustable position, the knob disk 5 is sleeved on the inner side of the support ring seat 4 and is coaxially rotatably connected with the support ring seat 4, the knob disk 5 is provided with a middle hole, and a first clamping guide assembly is provided on one side of the middle hole; the first bending mechanism is used to bend the profile in a first dimension, and the profile that has been bent in the first dimension is clamped and limited by the first clamping guide assembly during the process of passing through the middle hole and the first clamping guide assembly, and the knob disk 5 rotates relative to the support ring seat 4 for bending the profile in a second dimension.

[0033] This multi-dimensional profile bending machine is mainly based on the synergy of two bending mechanisms. First, the first bending mechanism bends the profile in the first dimension through the coordinated movement of the front pressure roller 1, the left pressure roller 2 and the right pressure roller 3. Specifically, the profile is placed between the three pressure rollers, and each pressure roller independently provides power to transport the profile. During the transportation process, the profile is bent in the horizontal direction by adjusting the front and rear displacement of the front pressure roller 1, and the bending curvature of the profile is controlled at the same time. In addition, by controlling the left and right displacement of the left pressure roller 2 and the right pressure roller 3, the center distance between the two pressure rollers can be adjusted to adapt to profiles of different thicknesses.

[0034] The profile that has been bent in the first dimension then enters the second bending mechanism. Specifically, the position of the support ring seat 4 is adjusted so that the profile can pass through the middle hole of the twisting plate 5 and be clamped and limited by the first clamping guide assembly. While the profile continues to be driven and transported by the rollers, the twisting plate 5 rotates relative to the support ring seat 4. This rotation applies torque to the profile, causing it to twist around its own axis, thereby achieving bending in the second dimension.

[0035] The bending machine of this embodiment combines and applies two bending mechanisms, which not only realizes the first-dimensional bending of the profile, but also can perform bending processing in the second dimension. This multi-dimensional bending capability enables the bending machine to handle more complex bending tasks, significantly improving the processing flexibility and application scope; at the same time, the coordinated work of the two bending mechanisms also ensures the continuity and accuracy of the bending process, improving the processing flexibility and application scope.

[0036] By combining the two bending mechanisms, the bending machine can handle bending tasks in two dimensions at the same time, shortening the production cycle and improving production efficiency;

[0037] The bending machine has a more compact structure and occupies less space, providing greater layout flexibility for the production site; at the same time, the compact design is easier to debug and maintain, further improving the convenience of use.

[0038] In some embodiments, the first clamping guide assembly includes four fixed blocks 6 distributed in a rectangular shape on one side of the rotary disk 5, and a roller 7 is connected between each two adjacent fixed blocks 6, wherein two opposite rollers 7 are used for rolling contact with the upper and lower end surfaces of the profile, and the other two opposite rollers 7 are used for rolling contact with the two side edges of the profile.

[0039] Specifically, the four fixing blocks 6 and the rollers 7 therebetween provide precise guidance and clamping for the profile, ensuring that the profile can remain stable during the torsion process, thereby improving the processing accuracy. The use of the rollers 7 in rolling contact with the profile reduces friction and wear, avoiding damage to the profile during the torsion process.

[0040] In some embodiments, a rotation driving device 8 is fixedly provided on the upper side of the support ring seat 4, and the rotation driving device 8 is connected to a worm gear, which is rotatably connected to the support ring seat 4. A circle of gear teeth is provided on the outer side of the knob disk 5, and the worm gear is meshingly connected to the gear teeth; both sides of the support ring seat 4 are provided with edging, which is used to cover and limit the edges of both sides of the knob disk 5.

[0041] Specifically, the worm is driven to rotate by the rotary drive device 8, and a circle of gear teeth is designed on the outer side of the knob disk 5. Since the meshing relationship between the gear teeth and the worm is very close, a precise transmission structure is formed. The knob disk 5 will hardly produce any deviation or shaking during the rotation process, and its rotation angle can be adjusted with extremely high precision, thereby achieving precise control of the rotation angle and ensuring high precision and stability of the profile bending processing; the edging design on both sides of the support ring seat 4 provides a stable support and limit for the knob disk 5, making the overall structure more compact and beautiful.

[0042] In some embodiments, the support ring seat 4 is connected to the machine 100 through an adjustment seat; the adjustment seat includes a mounting bracket 10, a slider 11, a guide rail 12, a lifting plate 13 and a lifting drive device 14, the lifting drive device 14 is fixedly connected to the machine 100, and is used to drive the lifting plate 13 to move up and down relative to the machine 100; the lifting plate 13 is connected to a plurality of vertical guide rods 15, and the guide rods 15 slide up and down with the machine 100 to guide the lifting plate 13 to move up and down; the guide rail 12 is fixedly arranged on the upper end surface of the lifting plate 13, the slider 11 is slidably connected to the guide rail 12, one side of the mounting bracket 10 is rotationally connected to the slider 11 through a swivel seat 16, and the other side is fixedly connected to the support ring seat 4.

[0043] Specifically, the lifting drive device 14 serves as a power source to drive the lifting plate 13 to move up and down relative to the machine table 100. The guide rod 15 ensures that the movement process is smooth and accurate, and prevents the lifting plate 13 from offsetting or shaking. The mounting bracket 10 is connected to the guide rail 12 through the sliding connection of the slider 11, and the rotating connection with the slider 11 through the swivel seat 16, so that the angle can be flexibly adjusted, so that the support ring seat 4 can be rotated to a suitable position according to the processing requirements. By accurately adjusting the position and angle of the support ring seat 4, it can be ensured that the relative position between the knob disk 5 and the profile reaches the optimal state, reducing processing errors, and improving processing accuracy and product quality. The design of the adjustment seat allows the height and angle of the support ring seat 4 to be flexibly adjusted according to different processing requirements, enhancing the processing adaptability and enabling it to cope with more types of profiles and processing tasks.

[0044] In some embodiments, the machine 100 is provided with a front guide groove, in which a front guide slider 17 is provided, and the front pressure roller 1 is vertically connected to the front guide slider 17; the machine 100 is connected to a front driving cylinder 9, which is used to drive the front guide slider 17 to slide back and forth in the front guide groove, thereby adjusting the front and rear displacement of the front pressure roller 1 to achieve the adjustment of the curvature of the profile.

[0045] Specifically, when the curvature of the profile needs to be adjusted, the front driving cylinder 9 is started, pushing or pulling the front guide slider 17 to slide back and forth in the front guide groove; the sliding of the front guide slider 17 drives the front pressure roller 1 to move back and forth, thereby changing the relative position between the front pressure roller 1 and the profile; as the position of the front pressure roller 1 changes, the profile bends under the joint action of the front pressure roller 1 and the left pressure roller 2 and the right pressure roller 3, and the curvature changes accordingly.

[0046] By driving the front guide slider 17 to slide accurately through the front driving oil cylinder 9, the front and rear displacement of the front pressure roller 1 can be accurately controlled, ensuring the accurate adjustment of the curvature of the profile to meet different processing requirements. The matching design of the front guide groove and the front guide slider 17 ensures the stability and accuracy of the front pressure roller 1 during movement, reduces errors and deviations during processing, and improves processing accuracy and product quality.

[0047] In some embodiments, the lower end of the front pressure roller 1 vertically penetrates the front guide slider 17 and is rotatably connected to the front guide slider 17; the lower side of the front guide slider 17 is connected to the front motor mounting seat 18, the front motor mounting seat 18 is connected to the front rotation drive motor 19, and the front rotation drive motor 19 is connected to the front pressure roller 1 to drive the front pressure roller 1 to rotate.

[0048] Specifically, during the processing, the front rotary drive motor 19 is started, and the rotary power is transmitted to the front pressure roller 1 through its connection with the front pressure roller 1; the front pressure roller 1 starts to rotate under the action of the rotary power, and acts on the profile in its rotating manner to realize the transportation of the profile.

[0049] In some embodiments, the machine 100 is provided with a transverse guide groove, in which a left guide slider 20 and a right guide slider 21 are provided, the left pressure roller 2 is vertically connected to the left guide slider 20, and the right pressure roller 3 is vertically connected to the right guide slider 21; the machine 100 is provided with a left adjustment mechanism and a right adjustment mechanism, the left adjustment mechanism is used to drive the left guide slider 20 to slide left and right in the transverse guide groove, and the right adjustment mechanism is used to drive the right guide slider 21 to slide left and right in the transverse guide groove, so as to adjust the center distance between the left pressure roller 2 and the right pressure roller 3.

[0050] Specifically, by driving the left and right guide sliders to slide through the left and right adjustment mechanisms, the center distance of the left and right pressure rollers can be flexibly adjusted, so that the machine can adapt to profiles of different widths or different processing requirements, thereby improving the processing adaptability; the coordinated design of the left and right guide sliders and the transverse guide grooves ensures the stability and accuracy of the left and right pressure rollers during movement, which helps to reduce processing errors and improve processing accuracy.

[0051] In some embodiments, the lower end of the left pressure roller 2 vertically penetrates the left guide slider 20 and is rotatably connected to the left guide slider 20; the lower side of the left guide slider 20 is connected to the left motor mounting seat, the left motor mounting seat is connected to the left rotation drive motor 22, the left rotation drive motor 22 is connected to the left pressure roller 2 to drive the left pressure roller 2 to rotate; the lower end of the right pressure roller 3 vertically penetrates the right guide slider 21 and is rotatably connected to the right guide slider 21; the lower side of the right guide slider 21 is connected to the right motor mounting seat, the right motor mounting seat is connected to the right rotation drive motor 23, the right rotation drive motor 23 is connected to the right pressure roller 3 to drive the right pressure roller 3 to rotate.

[0052] By adopting three independent motor drives, the rotation of each pressure roller is precisely controlled, reducing the problem of reduced processing accuracy caused by mechanical transmission errors; by integrating each motor directly on the corresponding slider, the motor follows the displacement of the slider, reducing the transmission structure and transmission errors, making the rotation of the pressure roller more precise, thereby improving processing accuracy.

[0053] In some embodiments, the left adjustment mechanism includes a left hand wheel 24 and a left threaded rod 25. An internal threaded hole is provided on the left side of the left guide slider 20. One end of the left threaded rod 25 is connected to the internal threaded hole of the left guide slider 20, and the other end extends out of the transverse guide groove and is connected to the left hand wheel 24; the right adjustment mechanism includes a right hand wheel 26 and a right threaded rod 27. An internal threaded hole is provided on the right side of the right guide slider 21. One end of the right threaded rod 27 is connected to the internal threaded hole of the right guide slider 21, and the other end extends out of the transverse guide groove and is connected to the right hand wheel 26.

[0054] The center distance between the left and right rollers can be adjusted by simply rotating the left or right hand wheel to adapt to profiles of different widths or processing requirements, making the equipment more flexible to cope with various processing tasks and improving the versatility and processing efficiency of the equipment. The precise adjustment of the left and right guide slide blocks is achieved through threaded connection, ensuring that the center distance between the left and right rollers can accurately meet the processing requirements, thereby improving the processing accuracy.

[0055] In some embodiments, the plate rolling machine includes a second clamping guide assembly arranged between the first bending mechanism and the second bending mechanism; the second clamping guide assembly includes a fixed plate 28 connected to the left pressure roller 2, the fixed plate 28 is connected to two upper and lower parallel clamping rollers 29, the other ends of the two clamping rollers 29 are connected to the column 30, and the column 30 is fixed to the machine platform 100.

[0056] When the profile enters the second clamping guide assembly, two upper and lower parallel clamping rollers 29 will tightly clamp the upper and lower end surfaces of the profile. The clamping force of the clamping rollers 29 can be fine-tuned by bolts to adapt to profiles of different widths and thicknesses.

[0057] By arranging a clamping and guiding assembly in front of the second bending mechanism, the profile can be pre-clamped and guided to ensure that it enters the second bending mechanism in the correct position and posture, reducing errors and deformations during the bending process and improving bending accuracy; by adjusting the position of the clamping roller, the starting point of the second bending of the profile can be accurately set, thereby achieving precise control of the bending position.

[0058] During the entire bending process, the second clamping and guiding assembly works closely with the first bending mechanism, the second bending mechanism and other related components to form a complete bending system, which achieves high-precision bending of the profile through precise coordination and control.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
