[0041] Specific embodiments of the titanium alloy laser induced bending device and method provided by the present invention:

[0042] See also Figure 1-15 The titanium alloy laser induced bending device comprises a bending component 1, an outer limit component 2, an inner limit component 3 and two welding machines 4.

[0043] The bending assembly 1 includes a row of several intermediate support bodies 5, and the center heights of the intermediate support bodies 5 are the same; bending rollers 6 are arranged at intervals on the upper and lower sides of the intermediate support bodies 5; two titanium alloy strips are allowed to pass continuously on the upper and lower sides of the intermediate support bodies 5, and the bending rollers 6 and the intermediate support bodies 5 bend the two titanium alloy strips passing through into two angle profiles 13 with openings facing each other.

[0044] The bending assembly 1 also includes a bending frame 7 and a motor 9 installed on the bending frame 7, and the bending roller 6 is rotatably installed on the bending frame 7; the ends of the two bending rollers 6 on the upper and lower sides of the same intermediate support body 5 are connected with gears 8 that mesh with each other. Specifically, a rotating shaft is passed through the center of the bending roller 6, and the rotating shaft is rotatably connected to the bending frame 7. Both ends of the rotating shaft pass through the bending frame 7 and extend to the outside of the bending frame 7, and one end of the rotating shaft is connected to the gear 8; the gears 8 are grouped in pairs, and the same group of gears 8 mesh with each other, so that the bending rollers 6 on the upper and lower sides of the same intermediate support body 5 turn in opposite directions, thereby realizing the same-direction movement of the titanium alloy belts on the upper and lower sides of the intermediate support body 5.

[0045] The output shaft of the motor 9 is connected to the bending roller 6; a belt transmission mechanism 10 is connected between the ends of the bending roller 6. Figure 1 As shown, in the present embodiment, three synchronously rotating servo motors 9 are provided to ensure the synchronization of the movement of the titanium alloy strip, and six groups of belt transmission mechanisms 10 are provided; the belt transmission mechanism 10 is connected to the ends of the rotating shafts of two adjacent bending rollers 6 at the same height of the lower layer; specifically, the motor 9 drives the lower bending roller 6 to rotate through the belt transmission mechanism 10, and the lower bending roller 6 drives the upper bending roller 6 to rotate through the gear 8, the upper bending roller 6 and the upper side of the intermediate support body 5 clamp the upper titanium alloy strip, move the titanium alloy strip, and gradually bend the upper titanium alloy strip into an angle profile 13; the lower bending roller 6 and the lower side of the intermediate support body 5 clamp the lower titanium alloy strip, move the titanium alloy strip, and gradually bend the lower titanium alloy strip into an angle profile 13, and the upper and lower angle profiles 13 correspond vertically.

[0046] The bending frame 7 is a trough-shaped structure with legs on the lower side. One end of the bending frame 7 is closed and the other end is open. The end wall of the bending frame 7 close to the welding machine 4, i.e. the closed end, is provided with two die holes 11 for the angle profiles 13 to pass through. The two die holes 11 correspond to each other up and down, and the two formed angle profiles 13 can just pass through and can correct the angle profiles 13. A plurality of rollers are provided inside the open end of the bending frame 7, and the rollers are used to support the flat titanium alloy strip to enter between the bending roller 6 and the intermediate support body 5.

[0047] There is a vertical gap between the upper titanium alloy strip and the lower titanium alloy strip. A support frame 12 is provided on the inner side of the bending frame 7, and the support frame 12 passes through the gap between the upper and lower titanium alloy strips; the intermediate support bodies 5 are all installed on the support frame 12. In this embodiment, the support frame 12 passes through the intermediate support body 5; there is also a vertical gap between the two formed angle profiles 13.

[0048] An annular groove is provided on the outer side of the bending roller 6, and the radial cross-section of the annular groove is an isosceles triangle; the vertex angle of the isosceles triangle cross-section of the annular groove of the bending roller 6 along the moving direction of the titanium alloy strip becomes smaller section by section, and each section includes at least two identical bending rollers 6. The specific bending rollers 6 include at least three specifications. In this embodiment, the bending roller 6 has three specifications. The vertex angle of the isosceles triangle cross-section of the annular groove on the bending roller 6 has three specifications of 160 degrees, 125 degrees and 90 degrees. In some other embodiments, more specifications of bending rollers 6 can be set to gradually bend the titanium alloy strip; in order to ensure the synchronization of the bending of the upper and lower titanium alloy strips, the bending rollers 6 on the upper and lower sides of the same intermediate support body 5 are the same.

[0049] The intermediate support body 5 includes a support plate 501, and four third rollers 502 in contact with the titanium alloy strip are rotatably installed on the edge of the support plate 501, and the center lines of the four third rollers 502 are located on the four sides of a rhombus; the upper and lower edges of the middle part of the support plate 501 are rotatably installed with top wheels 503, and the top wheel 503 corresponds to the middle part of the titanium alloy strip. The outer diameter of the top wheel 503 gradually decreases from the middle to the two ends, and the top wheel 503 corresponds to the inner side of the corner of the angle profile 13, so that the middle part of the titanium alloy strip is gradually bent, and the corner of the angle profile 13 is gradually formed, and the third rollers 502 are in contact with the two side walls of the angle profile 13.

[0050] There is a gap between the third roller 502 and the bending roller 6 on its outer side that is just enough for the titanium alloy strip to pass through, and the titanium alloy strip passes through the gap; the third roller 502 and the bending roller 6 are both in rolling contact with the titanium alloy strip; along the moving direction of the titanium alloy strip, the shape of the gap formed by each bending roller 6 and the third roller 502 of the corresponding intermediate support body 5 changes, so that the titanium alloy strip is gradually bent into an angle profile 13.

[0051] Specifically, corresponding to the bending roller 6, the intermediate support body 5 has at least three specifications. In the present embodiment, the intermediate support body 5 includes a plurality of first support bodies 51, a plurality of second support bodies 52 and a plurality of third support bodies 53 of different specifications arranged in sections along the moving direction of the titanium alloy strip; that is, a plurality of first support bodies 51 are arranged in the front section of the moving direction of the titanium alloy strip, a plurality of second support bodies 52 are arranged in the middle section, and a plurality of third support bodies 53 are arranged in the rear section; the angles of the larger angles of the rhombus corresponding to the third roller 502 on the first support bodies 51, the second support bodies 52 and the third support bodies 53 become smaller successively, and specifically, the angles of the larger angles of the rhombus are 160 degrees, 125 degrees and 90 degrees.

[0052] The titanium alloy laser induced bending method comprises the following steps: the bending component 1 continuously bends the upper and lower titanium alloy strips into two angle profiles 13 with openings facing each other, and uses laser to heat the middle of the two titanium alloy strips to induce the bending of the titanium alloy strips during the bending. Specifically, a plurality of laser heads 14 corresponding to the middle of the titanium alloy strips are arranged, and the laser heads 14 are connected to a laser generator, which is a prior art and is not shown in the attached drawings, and a fiber laser generator can be preferably used; the laser heads 14 irradiate and scan the middle of the titanium alloy strip during the bending process; the laser heads 14 are installed on the upper and lower sides of the support frame 12, facing the middle of the upper and lower titanium alloy strips respectively, and the laser increases the temperature of the middle of the titanium alloy strip, inducing the bending of the titanium alloy strip and facilitating the bending of the titanium alloy strip by the bending component 1.

[0053] The outer limit assembly 2 surrounds the outer sides of the two angle profiles 13 and makes the edges of the two angle profiles 13 close to each other. The inner limit assembly 3 is supported on the inner sides of the two angle profiles 13 and connected with the bending assembly 1. The two welding machines 4 are respectively located on both sides of the two angle profiles 13 and weld the two angle profiles 13 into a square tube. The inner limit assembly 3 is located on the downstream side of the bending assembly 1 along the moving direction of the angle profile 13. The welding machine 4 is located on the downstream side of the inner limit assembly 3. The two welding machines 4 are arranged opposite to each other. The welding machine 4 has a welding gun head, which corresponds to the seams on both sides of the two angle profiles 13. The outer limit assembly 2 is arranged in two groups, one of which is located on the outer side of the inner limit assembly 3 and can cooperate with the inner limit assembly 3 to limit the two angle profiles 13, so as to facilitate accurate welding. The other group is located on the downstream side of the welding machine 4 to suppress the stress deformation after the square tube is welded and ensure product quality and stability.

[0054] Since there is a vertical gap between the two angle profiles 13 just after being bent, an outer limit assembly 2 and an inner limit assembly 3 are set in front of the welding station to limit the two angle profiles 13 so that the two angle profiles 13 are close to each other and the edges of the two angle profiles 13 are fitted together to facilitate welding. Since the rigidity of the angle profile 13 relative to the titanium alloy strip is enhanced, the outer limit assembly 2, the inner limit assembly 3 and the welding machine 4 are at a distance from the bending assembly 1, so that the two angle profiles 13 can be close to each other.

[0055] The outer limit assembly 2 includes a first square drum frame 21 , and a plurality of first rollers 22 are rotatably mounted on four sides of the first square drum frame 21 . The first rollers 22 are attached to the outside of the angle profile 13 , and a support 23 is connected to the lower side of the first square drum frame 21 .

[0056] The inner limit assembly 3 includes a second square drum frame 31, and a plurality of second rollers 32 are rotatably mounted on the four sides of the second square drum frame 31. The second rollers 32 are attached to the inner side of the angle profile 13. The inner side of the second square drum frame 31 is connected to a core frame 33, and the core frame 33 is connected to a steel wire 34. The steel wire 34 is located in the two angle profiles 13, and the other end of the steel wire 34 is connected to the position between the two die holes 11 of the bending frame 7. The first square drum frame 21 and the second square drum frame 31 are both square cylindrical frames, and the centerline directions of the first roller 22 and the second roller 32 are perpendicular to the moving direction of the angle profile 13.

[0057] The outer limit assembly 2 and the inner limit assembly 3 can not only ensure the accurate position of the two angle profiles 13, but also correct the shape of the angle profile 13 before welding. The inner limit assembly 3 is connected to the bending frame 7 by a steel wire rope 34, and the steel wire rope 34 ensures the axial position of the inner limit assembly 3. The inner limit assembly 3 uses its own shape to limit the inner side of the angle profile 13 to ensure the accurate matching position of the two angle profiles 13; it solves the problem of the difficulty of realizing internal support in the continuous production of forming pipes in the prior art, which is conducive to improving and stabilizing product quality.

[0058] The device uses a rolling structure to contact the titanium alloy strip and the angle profile 13 during the bending of the titanium alloy strip and the limiting process of the angle profile 13, thereby reducing friction energy consumption; it can stably and continuously produce square tubes; compared with the method of correcting round tubes into square tubes in the prior art, the process steps are fewer; the efficiency is significantly improved; compared with the method of bending steel strips in sections in the prior art, the device can produce continuously with higher efficiency. After welding, the square tube is subjected to weld seam processing, traction and fixed-length cutting and segmentation in subsequent processes.

[0059] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
