[0002] In the modern door and window industry, the processing accuracy and efficiency of door and window round profiles directly affect the quality and production cost of the product. Door and window round profiles usually refer to finished round profiles of various aluminum alloys used to manufacture doors and windows. These round profiles are cut, welded, assembled and other processes to form the final door and window products. They have the advantages of light weight, high strength, light weight, strong corrosion resistance and strong plasticity.

[0003] A set of door and window guardrails usually consists of four round-shaped profiles. In the existing process of cutting and processing the round-shaped profiles of doors and windows, manual or semi-automatic equipment is often used to perform bevel cutting and drilling on a single round-shaped profile, which is difficult to meet the needs of large-scale production.

[0040] Refer to Figure 2 and Figure 3 , the feeding mechanism 4 includes a receiving bin 41 opened at the upper end of the workbench 1, a rectangular avoidance opening two 42 communicating with the receiving bin 41 is opened at the rear end of the workbench 1, third slide rails 43 are installed on the front and rear sides of the upper end of the workbench 1, electric sliders one 44 are installed on the two third slide rails 43, extension plates 45 are installed at the opposite ends of the two electric sliders one 44, a limit slide rod 46 is installed through the front extension plate 45, first lead screws 47 are rotatably installed at the upper and lower ends of the rear extension plate 45, limit circular plates are installed at both ends of the limit slide rod 46 and the opposite ends of the upper and lower first lead screws 47, clamping plates 48 are threadedly connected to the upper and lower first lead screws 47, the limit slide rod 46 slidably penetrates through the upper and lower clamping plates 48, a dual-axis motor one 49 is installed at the rear end of the rear electric slider one 44 through a motor base, the upper and lower output shafts of the dual-axis motor one 49 are fixedly connected with transmission shafts 50, and the upper and lower transmission shafts 50 are respectively connected to the corresponding first lead screws 47 through transmission belts.

[0041] First, a set of U-shaped profiles is conveyed side by side from left to right onto the workbench 1 by the peripheral feeding device. It should be noted that the U-shaped pressing plate 52 is initially attached to the upper end of the workbench 1. At this time, the front and rear trapezoidal baffles 54 respectively extend out of the corresponding rectangular slots 53 under the action of the compression springs. The staff pushes this set of U-shaped profiles so that their ends are all attached to the front and rear trapezoidal baffles 54, making the ends of multiple U-shaped profiles flush. Then, the two-shaft motor 49 controls the rotation of the upper and lower transmission shafts 50. The upper and lower transmission shafts 50 respectively drive the corresponding lead screws 47 to move through belt transmission. The upper and lower lead screws 47 respectively drive the corresponding clamping plates 48 to approach each other until the upper and lower clamping plates 48 jointly clamp multiple U-shaped profiles. Then, the front and rear pneumatic push rods 51 are started to jointly drive the U-shaped pressing plate 52 to move upward until the lower end surface of the U-shaped pressing plate 52 is higher than the upper end surfaces of multiple U-shaped profiles.

The upper and lower clamping plates 48 jointly drive multiple U-shaped profiles to move to the right by an appropriate distance. It should be noted that during this period, when the lower transmission shaft 50 and the corresponding lead screw 47 drive the transmission belt to move along, the rectangular avoidance opening 42 plays an avoidance role for the transmission belt. The equal division mechanism 5 uses two trapezoidal baffles 54 for initial positioning, which can make the ends of multiple U-shaped profiles flush. The feeding mechanism 4 can clamp multiple U-shaped profiles at the same time and drive them to move intermittently to the right, so as to achieve the effect of continuous cutting and processing.

[0042] See Figure 2 , Figure 3 , Figure 5 and Figure 6, the drilling and pushing mechanism 6 includes mounting grooves 61 symmetrically opened at the front and rear of the upper end of the workbench 1. Slide rails 62 are installed on the inner walls of the front and rear two mounting grooves 61. A slide rail 63 is installed on the inner wall of the mounting opening of the workbench 1. A drilling part 64 is jointly arranged on the front and rear two slide rails 62. A feeding part 65 is jointly arranged on the slide rail 63 and the drilling part 64; the drilling part 64 includes electric sliders 641 installed on the front and rear two slide rails 62 respectively. Drilling groups are arranged on the front and rear two electric sliders 641 respectively. The drilling group includes a U-shaped limiting plate 642 with an upward opening installed at the upper end of the electric slider 641. An inverted L-shaped limiting frame 643 is slidably installed on the inner wall of the U-shaped limiting plate 642. One end of the inverted L-shaped limiting frame 643 away from the U-shaped limiting plate 642 is slidably connected to the support plate 2. And two front and rear rectangular vertical plates 644 are installed at the upper end of each inverted L-shaped limiting frame 643. A plurality of support shafts 645 are evenly and rotatably penetrated through the rectangular vertical plate 644 close to the electric slider 641. The plurality of support shafts 645 are connected by a transmission belt. And drill bits 646 are installed at one ends of the plurality of support shafts 645 located on the workbench 1. The other ends of the plurality of support shafts 645 are rotatably connected to the rectangular vertical plate 644 away from the electric slider 641. A first motor 647 is installed at one end of the rectangular vertical plate 644 away from the workbench 1 and away from the electric slider 641. The output shaft of the first motor 647 rotatably penetrates through the corresponding rectangular vertical plate 644 and is fixedly connected to any one of the support shafts 645. The difference is that the plurality of support shafts 645 on the front side are shorter than the plurality of support shafts 645 on the rear side.

[0043] Refer to Figure 2 , Figure 3 and Figure 5 , the feeding part 65 includes a sliding seat 651 slidably installed on the slide rail 63. A dual-axis motor 652 is installed on the sliding seat 651. The front and rear two output shafts of the dual-axis motor 652 are respectively fixedly connected with lead screws 653. The front and rear two lead screws 653 are respectively threadedly connected to the corresponding inverted L-shaped limiting frames 643. Limiting circular plates are installed at the opposite ends of the front and rear two lead screws 653.

[0044] After the upper and lower clamping plates 48 drive multiple loop-shaped profiles to move rightward to an appropriate distance together, first start the front and rear pneumatic push rods 51 to jointly control the downward movement of the U-shaped pressing plate 52 to return to its original position. At this time, the U-shaped pressing plate 52 will press on multiple loop-shaped profiles. During this period, after the front and rear trapezoidal baffles 54 abut against multiple loop-shaped profiles, they will respectively retract into the corresponding rectangular grooves 53. Then, control the rotation of the support shafts 645 connected by the front and rear first motors 647 respectively. Under the driving action of the transmission belt, the multiple support shafts 645 on the front and rear sides will rotate synchronously, and the multiple support shafts 645 will drive the drill bits 646 to rotate synchronously. Then, control the front and rear lead screws three 653 to rotate forward by the double-shaft motor three 652. The front and rear lead screws three 653 drive the corresponding inverted L-shaped limit frames 643 to approach each other respectively. The front and rear inverted L-shaped limit frames 643 drive the corresponding rectangular vertical plates 644 to approach each other respectively. At this time, the multiple support shafts 645 on the front and rear sides will drive the corresponding drill bits 646 to approach each other respectively. Until after drilling multiple loop-shaped profiles, the front and rear first motors 647 stop working, control the automatic cutter two 576 to start working, and at the same time drive the lead screw four 575 to rotate forward by the forward and reverse motor two 574. The lead screw four 575 drives the sliding seat two 573 to move backward until the sliding seat two 573 drives the automatic cutter two 576 to move backward. During this period, the blade of the automatic cutter two 576 will move backward along the rectangular avoidance opening one 56 and cut multiple loop-shaped profiles at the same time.

[0045] After multiple loop-shaped profiles are cut, drive the lead screw four 575 to reverse by the forward and reverse motor two 574. The lead screw four 575 drives the sliding seat two 573 to move forward to return to its original position. At this time, the blade of the automatic cutter two 576 will move forward along the rectangular avoidance opening one 56 to return to its original position. Then, control the front and rear electric sliders 641 to drive the corresponding U-shaped limit plates 642 to move rightward respectively. At this time, the multiple support shafts 645 will jointly drive multiple loop-shaped profiles to move rightward to the upper side position of the bevel alignment mechanism 7, and the front and rear inverted L-shaped limit frames 643 will drive the double-shaft motor three 652 to move rightward through the corresponding lead screws three 653. During this period, the sliding seat one 651 will make an adaptive sliding compensation along the slide rail two 63. After the front and rear electric sliders 641 drive the corresponding U-shaped limit plates 642 to move rightward to the upper side position of the bevel alignment mechanism 7 respectively, control the front and rear lead screws three 653 to reverse by the double-shaft motor three 652. The front and rear lead screws three 653 drive the corresponding inverted L-shaped limit frames 643 to move away from each other respectively. The front and rear inverted L-shaped limit frames 643 drive the corresponding rectangular vertical plates 644 to move away from each other respectively. At this time, the multiple support shafts 645 on the front and rear sides will drive the corresponding drill bits 646 to move away from each other respectively to return to their original positions, and all the multiple drill bits 646 will disengage from the corresponding loop-shaped profiles. Then, control the front and rear electric sliders 641 to drive the corresponding U-shaped limit plates 642 to move leftward to return to their original positions.

[0050] See also Figure 3 , Figure 5 and Figure 7, two discharge ports 9 are provided at the rear end of the workbench 1, which are respectively communicated with the corresponding installation bins 71 on the left and right, and inclined material receiving frames 10 are respectively installed at positions corresponding to the discharge ports 9 in the two installation bins 71 on the left and right.

[0051] Refer to Fig.15 , after the front and rear electric sliding seats 641 drive the corresponding C-shaped limiting plates 642 to move leftward to restore their original positions respectively, if the wall thickness of the required cut square-section steel is relatively thick, first control the left secondary push rod 734 to drive the corresponding first stepped slide plate 736 to move upward, and the first stepped slide plates 736 on the left drive the corresponding second stepped slide plates 737 to move upward respectively until the lower end surface of the second stepped slide plate 737 on the left is flush with the upper end surface of the workbench 1. Then control the right secondary push rod 734 to drive the corresponding first stepped slide plate 736 to move upward, and the first stepped slide plates 736 on the right drive the corresponding second stepped slide plates 737 to move upward respectively until the lower end surface of the first stepped slide plate 736 on the right is higher than the upper end surface of the workbench 1. Then control the double-shaft motor II 732 to control the left and right lead screws II 733 to rotate forward, and the left and right lead screws II 733 drive the corresponding L-shaped mounting brackets 731 to approach each other respectively. During this period, the two second stepped slide plates 737 on the left and right will approach each other, and the second stepped slide plate 737 on the left and the first stepped slide plate 736 on the right push multiple square-section steels, so that the positions of multiple并排 square-section steels are adjusted to a stepped shape (as Fig.13 shown), it should be noted that the left rectangular sliding cylinder 831 is initially located at a position on the side close to the rear end of the support frame 3 in the corresponding guiding through hole 81, and the right rectangular sliding cylinder 831 is initially located at a position on the side close to the front end of the support frame 3 in the corresponding guiding through hole 81 (as Fig.10 shown). At this time, the cutting depths of the blades of the two automatic cutters I 835 on the left and right correspond to the upper cross plates of multiple square-section steels. Then control the automatic cutter I 835 on the left to start working, and at the same time control the electric slider II 838 on the left to drive the corresponding rectangular sliding cylinder 831 to slide along the guiding through hole 81. The rectangular sliding cylinder 831 will drive the corresponding automatic cutter I 835 to slide along the guiding through hole 81 through the support rod 833, so as to perform bevel cutting on the left side of the upper cross plates of multiple square-section steels. During this period, the support rod 833 on the left will drive the corresponding connecting slide rod 854 to slide horizontally along the U-shaped sliding groove 853 through the corresponding circular plate 832.

[0052] It should be noted that the pressure plate 852 is initially in the highest position. After the upper horizontal plates of the multiple circular profiles are cut, the servo motor 855 controls the rotating shaft 856 to rotate 90 degrees counterclockwise, and the rotating shaft 856 drives the two groups of cams 1 857 and cam 2 858 to rotate 90 degrees. At this time, the pressure plate 852 will move downward under the extrusion of the cam 1 857. Under the action of the compression spring, the circular plate 832 will drive the support rod 833 and the connecting slide rod 854 to slide downward synchronously. At this time, the cutting depth of the blade of the left automatic cutter 1 835 will correspond to the side plates of the multiple circular profiles, and the connecting rods on the left and right sides will be connected. The slide bar 854 will slide downward to the middle position along the corresponding sun-shaped slide groove 853, and control the electric slider 838 on the left to drive the corresponding rectangular slide cylinder 831 to slide in the opposite direction along the guide hole 81 to return to its original position, while the automatic cutter 835 on the right still does not work. The rectangular slide cylinder 831 will drive the corresponding automatic cutter 835 to slide in the opposite direction along the guide hole 81 to return to its original position through the support rod 833, thereby performing bevel cutting on the side panels of multiple round-shaped profiles. During this period, the support rod 833 on the left will drive the corresponding connecting slide bar 854 to slide horizontally along the sun-shaped slide groove 853 through the corresponding circular plate 832.

[0053] Continue to control the rotating shaft 856 to rotate counterclockwise by 180 degrees through the servo motor 855. The rotating shaft 856 drives the two groups of cams 857 and 858 to rotate by 180 degrees. At this time, the pressing plate 852 will move downward under the extrusion of the cam 858. Under the action of the compression spring, the circular plate 832 will drive the support rod 833 and the connecting slide rod 854 to slide downward synchronously. At this time, the cutting depths of the blades of the two automatic cutters 835 on the left and right will correspond to the lower cross plates of multiple loop-shaped profiles, and the two connecting slide rods 854 on the left and right both slide downward to the bottom position. The difference is that the connecting slide rod 854 on the left moves along the "day" - shaped trajectory, while the connecting slide rod 854 on the right only moves downward along the vertical direction. Then, control the electric slider 838 on the left to drive the corresponding rectangular sliding cylinder 831 to slide along the guiding through - hole 81 again. The rectangular sliding cylinder 831 will drive the corresponding automatic cutter 835 to slide along the guiding through - hole 81 through the support rod 833, so as to perform bevel cutting on the lower cross plates of multiple loop - shaped profiles. And continue to control the servo motor 855 to control the rotating shaft 856 to rotate counterclockwise by 90 degrees. The rotating shaft 856 will drive the two groups of cams 857 and 858 to rotate by 90 degrees to return to the original position. Under the action of the compression spring, the pressing plate 852 will move upward to return to the original position. At the same time, the connecting slide rods 854 on both sides will also slide upward along the vertical section of the "day" - shaped sliding groove 853 to the uppermost side. At this time, after the left - hand hypotenuses of multiple profiles are cut, control the two lead screws 733 on the left and right to reverse through the double - shaft motor 732. The two lead screws 733 on the left and right drive the corresponding L - shaped mounting brackets 731 to move away from each other respectively. During this period, the two stepped slide plates 737 on the left and right will move away from each other, and the loop - shaped profiles are no longer clamped. At this time, the cut waste will fall on the inclined material receiving rack 10 and slide into the discharge port 9. At the same time, control the two secondary push rods 734 on the left and right to drive the corresponding stepped slide plates 736 to move downward to return to the original position respectively.

[0054] Finally, control the secondary push rod 734 on the left to drive the corresponding stepped slide plate 736 to move upward again. The stepped slide plate 736 on the left drives the corresponding stepped slide plate 737 to move upward until the lower end surface of the stepped slide plate 736 on the left is higher than the upper end surface of the workbench 1. Then control the secondary push rod 734 on the right to drive the corresponding stepped slide plate 736 to move upward. The stepped slide plate 736 on the right drives the corresponding stepped slide plate 737 to move upward until the lower end surface of the stepped slide plate 737 on the right is flush with the upper end surface of the workbench 1 (as Fig.14As shown), the left and right lead screws 733 are then controlled to rotate forward by the dual-axis motor 732, and the left and right step slide plates 736 are moved closer to each other and clamp the multiple round-shaped profiles together, so that the positions of the multiple side-by-side round-shaped profiles are adjusted to a stepped shape opposite to the previous one, and the steps of graded cutting of the multiple round-shaped profiles in the previous step are repeated, and the right bevels of the multiple round-shaped profiles are cut at the same time. The waste materials after cutting will also fall on the inclined material receiving rack 10 and slide into the discharge port 9, waiting for unified processing. Finally, the multiple round-shaped profiles that have been cut can be taken out by the external material taking equipment.

[0055] The segmented cutting method is adopted to reduce the resistance between the blade and the circular profile during cutting and ensure the cutting quality.

[0056] If the wall thickness of the circular profile to be cut is thin, the pressure plate 852 will move downward to the lowest position under the extrusion of the cam 858, that is, there is no need for the cooperation of the sun-shaped slide groove 853, the cam 857 and the cam 858. The electric slider 838 on the left side directly drives the automatic cutter 835 to cut the left end bevels of multiple circular profiles at one time, and then the circular profile is adjusted in steps, and then the electric slider 838 on the right side drives the automatic cutter 835 to cut the right end bevels of multiple circular profiles at one time. At this time, the cutting efficiency will be effectively improved, and at the same time, the consistency of the cutting bevel angles is guaranteed, thereby ensuring the fit of the four profiles in a group during installation.
