Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profiles, in particular to an aluminum profile structure and cutting equipment for a broken bridge heat-insulating and cold-proof door. Background Art

[0002] With the continuous improvement of building energy-saving requirements, broken bridge heat-insulating and cold-proof doors have been widely used in modern buildings due to their excellent heat-insulating performance and energy-saving and environmental protection characteristics. As the core structural material of broken bridge heat-insulating and cold-proof doors, aluminum profiles not only bear the structural function, but also their appearance design directly affects the overall aesthetics of the door body. Traditional broken bridge heat-insulating and cold-proof doors generally adopt a regular rectangular cross-section structure. Although this design can meet the basic heat-insulating requirements, it is relatively single in shape, lacking visual variation and beauty. In the production and processing process of aluminum profiles, the quality control of the cutting link is crucial, which directly relates to the overall performance, structural stability and production efficiency of broken bridge heat-insulating and cold-proof door products. The existing technologies involved are as follows:

It also includes a lifting mechanism installed at the top of the base for driving the cutting mechanism to move up and down; a positioning mechanism connected to the lifting mechanism for fixing aluminum profiles of different specifications; a locking mechanism connected to the positioning mechanism for locking the positioning mechanism after the aluminum profile is fixed; this cutting device for aluminum profiles of doors and windows can automatically position and lock aluminum profiles of different specifications;

[0004] 2. CN119175622A, a production cutting device for aluminum profiles of doors and windows with a protection structure, includes a base and a bottom plate. One end of the base is fixedly connected with a bracket, the inner side of the bracket is rotatably connected with a power roller, an aluminum profile is placed on the top of the power roller, and upper clamping mechanisms are fixedly connected on both sides of the vertical center line at the top of the bracket.

Therefore, they are only suitable for placing aluminum profiles with regular shapes, that is, aluminum profiles with a rectangular cross-section appearance. For aluminum profiles with a special-shaped cross-section appearance, after the aluminum profile is placed on the device, even if the device has the function of clamping the aluminum profile, the aluminum profile will shake during the cutting process, resulting in poor cutting quality and affecting production efficiency. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

[0044] It should be noted that a single-chip microcomputer is set in the control panel 3. By programming the single-chip microcomputer, the control of the device can be realized. Since it is a prior art, it will not be elaborated here; there are two modes for the mode-changing cutter 5 and the feeder 6. One is to match the special-shaped aluminum profile, and the other is to match the regular aluminum profile. According to the shape of the aluminum profile, select the working mode of the mode-changing cutter 5 and the feeder 6 to clamp and fix the aluminum profile. When cutting the aluminum profile, adjust the distance between the mode-changing cutter 5 and the stopper 7 to the length of the aluminum profile to be cut, then insert the aluminum profile into the feeder 6, the feeder 6 clamps and fixes the aluminum profile, one end of the aluminum profile fits against the stopper 7 when the feeder 6 works, and then the mode-changing cutter 5 works to clamp and cut the aluminum profile;

[0045] Specifically, the mode-changing cutter 5 includes a cutting outer cover 51, an outer convex groove is arranged on one side wall surface of the cutting outer cover 51, a cutting structure 52 is arranged on the inner side wall surface of the cutting outer cover 51 and at the position of the outer convex groove, and a distance measuring instrument 53 is installed on the lower wall surface of the cutting outer cover 51 corresponding to the machine case 2;

[0046] It should be noted that the distance measuring instrument 53 is used to measure the distance between the mode-changing cutter 5 and the limiting structure, so that the staff can adjust the position of the mode-changing cutter 5 through the control panel 3, and the outer convex groove is used to accommodate the cutting structure 52;

[0047] Specifically, the feeder 6 includes a feeding outer cover 61. Chutes are provided on the opposite inner wall surfaces of the feeding outer cover 61, and sliders 62 are movably installed on the chutes.

[0049] It should be noted that the mold changer 8 inside the cutting outer cover 51 is fixedly installed on the inner wall surface of the cutting outer cover 51. The mold changer 8 inside the feeding outer cover 61 is movably installed on the chute through the slider 62. Through the expansion and contraction of the first cylinder 63, the height of the mold changer 8 can be adjusted.

[0050] Specifically, drivers 9 are installed on the lower wall surfaces of the cutting outer cover 51 and the feeding outer cover 61, and the drivers 9 are mutually matched with the guide 4.

[0051] It should be noted that the cutting outer cover 51 and the feeding outer cover 61 can move on the base groove 1 through the cooperation of the driver 9 and the guide 4.

[0052] Specifically, the mold changer 8 includes a cross table 801 and a commutation structure provided on both sides of the cross table 801. An irregular support block 818 is installed on the upper wall surface of the cross table 801 through a first bolt 802. An irregular surface groove 803 is provided on the upper wall surface of the irregular support block 818. A regular support block 805 is installed on the lower wall surface of the cross table 801 through a second bolt 804. A flat surface groove 806 is provided on the lower wall surface of the regular support block 805.

[0053] It should be noted that during the use of the device, multiple irregular support blocks 818 matching the aluminum profiles in different shapes can be prepared and installed on the cross table 801 through the first bolts 802 as needed. The regular support block 805 is detachably installed on the cross table 801 through the second bolt 804, which is convenient for the maintenance of the regular support block 805. The irregular surface groove 803 is used to match the surface of the irregular aluminum profile, and the flat surface groove 806 is used to match the regular aluminum profile.

[0054] Specifically, the commutation structure includes a first motor 807, which is installed on the side wall surface of the horizontal table 801. Second cylinders 808 are arranged on both sides of the first motor 807 on the horizontal table 801. A clamping plate 809 is installed at the telescopic end of the second cylinder 808. A socket matching the clamping plate 809 is provided on the side wall surface of the horizontal table 801. The clamping plate 809 is movably inserted into the socket. A C-shaped frame 810 is fixedly sleeved on the second cylinder 808. The driving end of the first motor 807 is movably inserted into the C-shaped frame 810. A first guide rod 811 is installed on the clamping plate 809, and the first guide rod 811 is movably inserted into the C-shaped frame 810. Fixed structures are installed on both the upper and lower wall surfaces of the horizontal table 801;

[0055] Specifically, the fixed structure includes an n-shaped frame 812. Third cylinders 813 are inserted on both side wall surfaces of the n-shaped frame 812. Two fourth cylinders 814 are symmetrically inserted on the upper wall surface of the n-shaped frame 812. First pressure sensors 815 are installed at the telescopic ends of the two fourth cylinders 814 and the telescopic end of the third cylinder 813. A pressing plate 816 is arranged on the first pressure sensor 815. A second guide rod 817 is installed on the pressing plate 816, and the second guide rod 817 is movably inserted into the n-shaped frame 812;

[0056] It should be noted that when cutting profiled aluminum profiles, the profiled support block 818 faces upward. The profiled aluminum profile is placed on the profiled surface groove 803 so that the two fit and match each other. At this time, the second cylinder 808 is in the extended state, and the clamping plate 809 is inserted into the socket to support the horizontal table 801. Subsequently, the third cylinder 813 extends, and the pressing plate 816 on it clamps both sides of the profiled aluminum profile. By extending the two fourth cylinders 814, the pressing plates 816 on them are pressed against the aluminum profile to fix the aluminum profile. When fixing the aluminum profile, once the first pressure sensor 815 detects that the pressure value reaches the set value, the cylinder connected to it stops extending;

[0057] When cutting regular aluminum profiles, control the second cylinder 808 to contract so that the clamping plate 809 disengages from the socket. Through the operation of the second motor 527, the horizontal table 801 rotates 180 degrees. At this time, the regular support block 805 faces upward. The regular aluminum profile is placed on the plane groove 806 so that the two fit and match each other. Then, through the operation of the fixed structure, the regular aluminum profile is fixed;

[0058] By closely fitting with the aluminum profile, the fixing quality of the aluminum profile is guaranteed, the shaking of the aluminum profile during cutting is prevented, and the cutting quality and cutting efficiency are improved;

[0059] Specifically, the cutting structure 52 includes two cross tie rods 521. The two cross tie rods 521 are installed on the inner side wall surface of the cutting outer cover 51 and are located at the outer convex groove part. A moving block 522 is movably installed on the two cross tie rods 521. A hydraulic cylinder 523 is arranged between the moving block 522 and the inner side wall surface of the cutting outer cover 51. A connecting frame 524 is installed on the lower wall surface of the moving block 522. A rotating shaft 525 is movably inserted on the connecting frame 524. A saw disk 526 is fixedly sleeved on the rotating shaft 525. One end of the rotating shaft 525 is installed with a second motor 527, and the second motor 527 is fixed on the outer side wall surface of the connecting frame 524;

[0060] It should be noted that in the non-cutting state, the saw disk 526 is located at the outer convex groove. When cutting is required, the second motor 527 works to drive the rotating shaft 525 to drive the saw disk 526 to rotate. At the same time, the hydraulic cylinder 523 works to move the moving block 522 on the two cross tie rods 521 to cut the aluminum profile;

[0061] Specifically, the guide 4 includes mounting grooves 41 symmetrically arranged on the opposite inner wall surfaces of the base groove 1 and racks 42. The racks 42 are installed parallel to the mounting grooves 41 and are located below the mounting grooves 41;

[0062] Specifically, the driver 9 includes two vertical frames 91 symmetrically arranged on the lower wall surfaces of the cutting outer cover 51 and the feeding outer cover 61 and a third motor 92. A cross frame 93 is installed on the outer side wall surface of the vertical frame 91. The cross frame 93 is movably inserted on the mounting groove 41. A plurality of hemispherical seats 94 are embedded on the upper and lower wall surfaces of the cross frame 93. A rotating ball 95 is movably installed on each hemispherical seat 94. The rotating ball 95 is movably attached to the inner side wall surface of the mounting groove 41. The driving end of the third motor 92 is installed with a gear 96, and the gear 96 meshes with the rack 42;

[0063] It should be noted that when the cutting device 5 and the feeding device 6 need to move in the mode change, the third motor 92 works to drive the gear 96 to rotate. Under the meshing of the gear 96 and the rack 42 and the matching of the cross frame 93 and the mounting groove 41, the cutting device 5 and the feeding device 6 can move. The plurality of hemispherical seats 94 and the rotating balls 95 are used to assist the cross frame 93 to move in the mounting groove 41 to reduce the friction coefficient;

[0064] Specifically, the limiter 7 includes a window 71. The window 71 is opened on the side wall surface of the chassis 2. A fifth cylinder 72 is installed on the inner side wall surface of the chassis 2. A baffle 73 is installed at the telescopic end of the fifth cylinder 72. A convex block is arranged at the central part of the side wall surface of the baffle 73, and the convex block is used to connect with the telescopic end of the fifth cylinder 72. A second pressure sensor 74 is installed on the baffle 73, and a fitting plate 75 is installed on the second pressure sensor 74;

[0065] Specifically, a connecting block 76 is installed on the baffle 73, and a third guiding rod 77 is movably inserted into the connecting block 76. The third guiding rod 77 is installed on the chassis 2;

[0066] It should be noted that during the operation of the device, first, the aluminum profile is passed through the feeder 6 and then through the mode-changing cutter 5. When the first cylinder 63 is in the contracted state, the special-shaped surface groove 803 or the flat surface groove 806 in the feeder 6 and the mode-changing cutter 5 are on the same plane. The aluminum profile is fixed by the feeder 6. At this time, the aluminum profile is in contact with the die-changing device 8 in the mode-changing cutter 5. When it is necessary for the feeder 6 to clamp the aluminum profile and move, the first cylinder 63 extends, causing the die-changing device 8 in the feeder 6 to rise, and the aluminum profile rises accordingly. At this time, the aluminum profile leaves the die-changing device 8 in the mode-changing cutter 5, preventing the aluminum profile from rubbing against the die-changing device 8 in the mode-changing cutter 5. When the feeder 6 moves to one end of the aluminum profile and contacts the fitting plate 75, at this time, the second pressure sensor 74 detects the pressure value, and the feeder 6 stops moving. Subsequently, the first cylinder 63 contracts and resets. At this time, the aluminum profile is in contact with the die-changing device 8 in the mode-changing cutter 5. Subsequently, the die-changing device 8 in the mode-changing cutter 5 clamps the aluminum profile, and then the cutting structure 52 works to cut the aluminum profile. After cutting is completed, the fifth cylinder 72 contracts, and the fitting plate 75 moves on the third guiding rod 77 through the connecting block 76, exposing the window 71. The die-changing device 8 in the mode-changing cutter 5 releases the aluminum profile, and the staff can collect the aluminum profile at the window 71;

[0068] It should be noted that the shaping surface 10 can be arc-shaped or other shapes, as well as a combination of an arc and other shapes, to meet the shaping of the broken bridge heat-insulating and cold-proof door. It is only necessary to open a special-shaped surface groove 803 on the special-shaped support block 818 that matches its shape. The two longitudinal connecting surfaces 11 are used to connect the shaping surface 10 and the inner side surface 12.
