[0043] It should also be noted that a lifting ring 10 is provided to facilitate lifting and installation.

[0044] In one embodiment, Figure 1 and Figure 2 As shown, the power wheel assembly 2 includes a first support 201 bolted to the bracket 1 and a first reduction motor bolted to the first support 201. A power wheel 202 for tightly fitting with the profile is rotatably connected to the first support 201, and the output end of the first reduction motor is fixedly connected to the power wheel 202.

[0045] It should be noted that both ends of the power wheel 202 are rotatably connected to the first support 201 by means of bearings, so that the power wheel 202 can rotate more smoothly.

[0049] It should be noted that the first ranging laser radar 6 detects the longitudinal distance information between it and the second slider and uploads it to the host computer. The host computer obtains the lifting amount based on this and adjusts the feed amount of the lifting wheel in real time according to the required bending radius, thereby ensuring the accuracy of the bending radius.

[0050] It should also be noted that a dovetail protrusion is provided at the lower end of the second slider, and a dovetail groove is correspondingly provided on the bracket 1 ; the output end of the second reduction motor 501 is connected to the second screw rod 503 through a coupling 502 .

[0053] In one embodiment, Figure 1 and Figure 6As shown, the roller clamping assembly 4 includes a fourth support 401 bolted to the bracket 1, the lower end of the fourth support 401 is rotatably connected to the first roller 402, both sides of the upper end of the fourth support 401 are vertically threadedly connected to the third screw rod 405, the lower ends of the two third screw rods 405 are vertically rotatably connected to the support seat 403, and the second roller 404 parallel to the first roller 402 is rotatably connected between the two support seats 403.

[0056] In one embodiment, the upper portion of the third screw rod 405 is connected to a rocker rod 406 .

[0057] In one embodiment, Figure 1 and Figure 7 As shown, two fifth supports 11 are bolted to the bracket 1, a lifting cylinder 12 is longitudinally fixedly connected to the fifth support 11, a mounting bracket 13 is slidably connected to the fifth support 11, the mounting bracket 13 is fixedly connected to the output end of the lifting cylinder 12, a connecting member 14 is rotatably connected to the mounting bracket 13, and a roller 15 for close contact with the profile is fixedly connected to the upper end of the connecting member 14;

[0061] In one embodiment, an input module for inputting profile model, arch radius, arch number and arch outer arc length is provided in the host computer.

[0062] In one embodiment, a storage module is provided in the host computer.

[0063] It should be noted that, regardless of whether it is single-radius arch forming or multi-radius arch forming, the storage module can store the arch data of the profile steel that has been produced, so that the corresponding processing parameters can be directly called up during the next production to carry out the production operation directly, thereby greatly shortening the changeover time, improving production efficiency, and ensuring the consistency of previous and subsequent production to improve production quality.

[0064] To sum up, the utility model can realize the multi-radius bending function of profile steel and improve the bending accuracy; the utility model can improve the digitalization and intelligent control of the production of curved profile steel; the utility model can improve the production quality and production efficiency of curved profile steel, reduce the number of operators and reduce the operating difficulty of operators; the utility model can also import relevant production data into the central control system of the upper computer to facilitate uploading and retrieving relevant data, thereby realizing data management.

[0065] The working process of this utility model is:

[0066] Input the model, bending radius, number of bends and outer arc length of the incoming profile steel into the host computer, so that these data are transmitted to the central control system in the host computer, and then use these data to perform the profile steel bending operation;

[0067] The profile steel enters the three roller clamping assemblies 4 under the action of external thrust, and the roller clamping assemblies 4 and the driven wheel assembly 3 are manually adjusted to limit the vertical and longitudinal positions of the profile steel, and to enable the driving wheel assembly to compact the profile steel;

[0068] The lifting wheel assembly 5 is lifted to bend the profile steel; during the bending process, the first ranging laser radar 6 detects the lifting position of the lifting wheel, and the second ranging laser radar 7 detects the real-time curvature change of the profile steel curvature. When the curvature change is about to exceed the standard curvature, the first ranging laser radar 6 uploads the measured information to the central control system, and automatically adjusts the lifting position of the lifting wheel accordingly. Thus, by cooperating with the first ranging laser radar 6 and the second ranging laser radar 7, real-time curvature detection and real-time adjustment of the profile steel can be achieved, thereby achieving precise curvature.

[0069] After the first encoder 8 detects that the first radius of the profile steel is bent, the lifting wheel retracts and waits for the power wheel 202 to feed the profile steel before lifting it again to bend the profile steel into the second radius;

[0070] Then, the bending of the remaining radius is completed in the same way until the second encoder 9 detects that the processing of the profile steel is completed.

[0071] It should be noted that the five-axis cold bending machine can also produce single-radius arches, that is, once the length of the outer arc of the arch reaches the specified length, the arch bending will stop and the relevant data will be submitted to another cutting system for cutting to a fixed length.
