[0024] The following describes a pipe cutting machine for manufacturing automobile parts according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the pipe cutting machine for automobile parts manufacturing according to the embodiment of the present invention may include a mounting cavity 100 , a rotating roller 200 , a driving device 300 , a moving device 400 , an auxiliary device 500 and a laser cutting head 600 .

[0026] The two rotating rollers 200 are rotatably disposed in the installation cavity 100 , and the driving end of the driving device 300 is connected to the rotating end of the rotating rollers 200 .

[0027] The moving device 400 is movably disposed on the installation cavity 100 and is locked by bolts. The auxiliary device 500 is disposed on the top of the moving device 400 .

[0028] like Figure 2 As shown, the auxiliary device 500 includes a mounting frame 510 , a rotating arm 520 , a second driving motor 530 , a pressing roller structure 540 and a pushing structure 550 .

[0029] Among them, the mounting frame 510 is set on the top of the mobile device 400, the middle section of the rotating arm 520 can be rotatably set on the mounting frame 510, and the rotation center of the rotating arm 520 is connected to the output end of the second drive motor 530, and the clamping roller structure 540 and the pushing structure 550 are respectively set at both ends of the rotating arm 520.

[0030] It should be noted that the pressing roller structure 540 is close to the discharge end of the rotating roller 200, and the pushing structure 550 is away from the discharge end of the rotating roller 200. Then, the pressing roller structure 540 can press the top of the pipe when cutting the pipe, and the working end of the pressing roller 542 rotates with the pipe. After the cutting is completed, the pushing structure 550 can drive the uncut pipe to discharge the cut pipe.

[0031] like Figure 4 As shown, the laser cutting head 600 is disposed on the top inner wall of the moving device 400 to cut the rotating pipe.

[0032] It should be noted that the laser cutting head 600 is located between the two rotating rollers 200 , so when the laser cutting head 600 cuts the pipe, the rotating rollers 200 will not be damaged.

[0033] To clearly illustrate the above embodiment, in one embodiment of the present invention, the pressing roller structure 540 includes a roller frame 541 and a pressing roller 542 .

[0034] The roller frame 541 is pivotally disposed at the end of the rotating arm 520 , and the pressing roller 542 is rotatably disposed in the roller frame 541 .

[0035] As a possible scenario, a hinge is provided on the top of the roller frame 541, and the end of the rotating arm 520 is hingedly connected to the hinge. When the roller frame 541 descends following the rotating arm 520, the pressure roller can fit with the top of the pipe under the action of the hinge.

[0036] To clearly illustrate the above embodiment, in one embodiment of the present invention, the pushing structure 550 includes a roller frame 551 , a rolling wheel 552 and a third driving motor 553 .

[0037] The roller frame 551 is pivotally disposed at the end of the rotating arm 520 , and the rolling wheel 552 is rotatably disposed on the roller frame 551 and connected to the output end of the third driving motor 553 .

[0038] As a possible scenario, a hinge is provided at the top of the roller frame 551, and the end of the rotating arm 520 is hingedly connected to the hinge. When the roller frame 551 descends following the rotating arm 520, the roller can fit with the top outer wall of the pipe. Through the rotation of the roller, the pipe is moved forward and the cut pipe is pushed out.

[0039] Specifically, before the relevant staff cuts the pipe, first, the relevant staff places the pipe on two rotating rollers 200, and the two sides of the bottom of the pipe are respectively in contact with the two rotating rollers 200. Then, the relevant staff drives the second drive motor 530 to rotate the rotating arm 520, so that the pressing roller structure 540 is pressed on the top of the pipe, that is, when the pressing roller 542 contacts the top of the pipe, the roller frame 541 rotates, so that the pressing roller 542 and the pipe have a higher fit.

[0040] Next, the relevant staff starts the driving device 300, and the rotating roller 200 rotates to drive the pipe to rotate. The relevant staff then turns on the laser cutting head 600 to cut the pipe while it rotates.

[0041] After the cutting is completed, the relevant staff controls the second drive motor 530 to rotate the rotating arm 520, thereby separating the pressing roller structure 540 from the cut pipe, and the pushing structure 550 contacts the pipe, that is, the rolling wheel 552 fits the uncut part of the pipe, and starts the third drive motor 553, so that the rotation of the rolling wheel 552 drives the pipe to move toward the discharge end, thereby pushing out the cut part of the pipe.

[0042] In one embodiment of the present invention, Figure 3 As shown, the driving device 300 includes a first driving motor 310 , a driving wheel 320 , a driven wheel 330 , an auxiliary wheel 340 and a transmission belt 350 .

[0043] Among them, the first drive motor 310 is arranged in the installation cavity 100, the driving wheel 320 is arranged on the output end of the first drive motor 310, the two driven wheels 330 are coaxially arranged with the two rotating rollers 200 respectively, the auxiliary wheel 340 is rotatably arranged below the middle of the two driven wheels 330, and the transmission belt 350 connects the driving wheel 320, the two driven wheels 330 and the auxiliary wheel 340.

[0044] It should be noted that a notch is provided at the discharge end of the installation cavity 100 to facilitate the discharge of the pipe. The provision of auxiliary rollers can prevent the transmission belt 350 between the two driven wheels 330 from blocking the discharge of the pipe.

[0045] In one embodiment of the present invention, Figure 4 As shown, the moving device 400 includes a slide rail 410 , a slider 420 and a moving frame 430 .

[0046] The two slide rails 410 are respectively arranged on both sides of the installation cavity 100 , the two sliders 420 are respectively slidably arranged on the two slide rails 410 , and both ends of the movable frame 430 are respectively connected to the two sliders 420 .

[0047] It should be noted that the relevant staff can adjust the movable device 400 according to the length of the pipe to be cut, that is, by loosening the locking bolt on the slider 420 and then pushing the slider 420 to move on the slide rail 410, the laser cutting head 600 on the movable frame 430 follows the movable frame 430 to move to the desired position, and after reaching the desired position, retighten the locking bolt.

[0048] In addition, two ends of the movable frame 430 are respectively provided with avoidance slots 431 to avoid the rotation range of the rotating arm 520 .

[0049] In one embodiment of the present invention, the laser cutting head 600 includes a laser generator, a focusing lens, and a cooling system.

[0050] The laser generator is arranged on the top inner wall of the moving device 400, the focusing mirror is arranged at the output end of the laser generator for focusing the laser beam onto the surface of the pipe, and the cooling system is arranged around the laser generator for cooling the laser cutting head 600 to prevent overheating.

[0051] It should be noted that the focusing mirror can be set on a lifting frame, and the lifting frame is set on the movable frame 430. By changing the position of the focusing mirror, it can be ensured that the focus is effectively focused on the pipe when cutting pipes of different diameters.

[0052] In summary, according to the embodiment of the utility model, the pipe cutting machine for automobile parts manufacturing can not only ensure the stability of the clamping and cutting of the pipe by lifting and lowering the clamping roller structure 540 and cooperating with the two rotating rollers 200 at the bottom, but also can push the uncut pipe forward through the pushing structure 550 after the cutting is completed to realize feeding.
