They not only have multiple functions such as lighting, ventilation, wind and rain protection, heat preservation, sound insulation, dust prevention, and anti-theft, but are also important components for realizing the thermal, acoustic and light environment of buildings. Aluminum alloy door and window frame cutting machines are equipment specially used for cutting aluminum alloy door and window frames.

[0017] Beneficial effects of the present invention:

[0018] 1. From the above description, it can be seen that the second motor can be used to drive the screw to rotate, thereby driving the slider to move left and right. As the slider moves left and right, the support rod connected to it will tilt accordingly, and its tilt angle is adjusted according to actual needs. This tilting action drives the cross plate provided with the first motor to rotate obliquely upward, so that the saw blade part gradually exposes the cutting plate, and the exposed area gradually increases with the rotation of the cross plate, thereby achieving the effect of cutting workpieces of different thicknesses. On this basis, the L plate is pushed by the cylinder to flip the L plate outward, driving the saw blade to move inward, so that the angle between the saw blade and the cutting plate becomes smaller, thereby achieving the effect of adjusting the cutting angle.

[0019] 2. During cutting, the servo motor drives the fixed rod to rotate, and the fixed rod drives the transmission rod to rotate, thereby driving the limit column to slide in the slide groove opened on the turntable. At the same time, the transmission rod rotates to drive the two connecting rods to move, thereby driving the two clamping plates to move closer or farther away from each other. When the two clamping plates approach each other, the workpiece on the cutting plate can be clamped and fixed, thereby effectively preventing the aluminum alloy door and window frames from shifting or shaking due to uneven force or improper operation during the cutting process, improving the cutting stability and ensuring the processing accuracy.

[0020] 3. When the position angle of the workpiece needs to be adjusted, the third motor is used to drive the first bevel gear to rotate, and then the second bevel gear is driven to rotate. The rotation of the second bevel gear can drive the turntable with the clamping mechanism to rotate, and then the workpiece fixed by the clamping mechanism is driven to rotate, so as to adjust the position of the workpiece, thereby achieving the effect of flexible cutting.

[0021] 4. Before cutting the workpiece, the circular gear is driven by the driving motor to rotate, and then the tooth column set in the hollow tube is driven to move up and down, so as to drive the top plate to move up and down. The up and down movement of the top plate can adjust the distance between the clamping plate and the cutting plate to ensure that the clamping plate can fully contact the workpiece to be cut, adapt to aluminum alloy door and window frames of different thicknesses, and improve cutting stability.

[0022] 5. Push the L plate through the cylinder, and when the L plate flips to the top, push the bending rod to slide in the cutting plate, and then push the push plate to slide on the cutting plate, push the workpiece that has been cut back out of the cutting area, making it easier to take and improving the safety of the cutting work.

[0038] Height adjustment components 14, two height adjustment components 14 are symmetrically arranged between the cutting plate 2 and the top plate 3, and are used to adjust the height of the top plate 3;

[0039] The clamping mechanism 18 is arranged on the top plate 3 and is used to fix the aluminum alloy door and window frames.

[0040] Preferably, when the cutting machine is needed to cut aluminum alloy door and window frames, the workpiece to be cut is placed on the cutting plate 2, and then the driving motor 1401 is started. When the driving motor 1401 is working, the circular gear 1402 can be driven to rotate. When the circular gear 1402 rotates, the tooth column 1403 in the hollow tube 1404 can be driven to move up and down through the hole opened on the hollow tube 1404, thereby driving the top plate 3 to move up and down, thereby adjusting the clamping plate 1806 to a suitable position to clamp the workpiece placed on the cutting plate 2, and then starting the servo motor arranged in the turntable 19 to drive the fixed rod 1801 to rotate. When the fixed rod 1801 rotates, the transmission rod 1802 can be driven to rotate. When the transmission rod 1802 rotates, the limit rod 1806 can be driven to rotate. The positioning column 1804 slides in the slide groove provided on the turntable 19, thereby driving the two clamping plates 1806 to move closer to or away from each other. When the two clamping plates 1806 are close to each other, the workpiece on the cutting plate 2 can be clamped and fixed. When cutting or after cutting is completed, when the position of the workpiece needs to be adjusted for secondary cutting, the third motor 15 is started. When the third motor 15 is working, it drives the first bevel gear 16 to rotate. When the first bevel gear 16 rotates, it drives the second bevel gear 17 to rotate and then drives the turntable 19 to rotate. When the turntable 19 rotates, it drives the clamping mechanism 18 arranged under the turntable 19 to rotate, thereby driving the workpiece fixed by the clamping mechanism 18 to rotate, so as to adjust the position of the workpiece, and then start the first motor 8 to make the saw blade 9 start Work, cut the workpiece, if encountering a thicker workpiece during cutting, start the second motor 1001 to drive the screw 1002 to rotate, the rotation of the screw 1002 can drive the slider 1003 to move left and right, the movement of the slider 1003 can make the support rod 1005 tilt, and then push the cross plate 7 obliquely upward, the movement of the cross plate 7 can drive the first motor 8 and the saw blade 9 to move upward, so that the part of the saw blade 9 exposed on the cutting plate 2 becomes larger, and then workpieces of different thicknesses can be cut. If there is a special requirement to adjust the cutting angle, start the cylinder 11 set on the bottom plate 1 to work, and when the cylinder 11 works, it pushes the L plate 5 forward. In the process of the L plate 5 being pushed, the slide bar 12 will slide along the slide groove provided on the vertical plate 4 to prevent the L plate from sliding. 5 is offset. When the L plate 5 moves, the saw blade 9 can be driven to swing backward, so that the angle between the saw blade 9 and the cutting plate 2 is changed, so that the cutting angle of the saw blade 9 can be adjusted, and the exposed part becomes more, so as to cut workpieces of different thicknesses. If there is a special requirement to adjust the cutting angle, the cylinder 11 set on the bottom plate 1 is started to work. When the cylinder 11 works, it pushes the L plate 5 forward. In the process of the L plate 5 being pushed, the slide bar 12 will slide along the slide groove provided on the vertical plate 4 to prevent the L plate 5 from offset. When the L plate 5 moves, it drives the saw blade 9 to swing backward, so that the angle between the saw blade 9 and the cutting plate 2 is changed, so that the cutting angle of the saw blade 9 can be adjusted. After the cutting is completed, the cylinder 11 pushes the slide bar 12 to the top of the slide groove on the vertical plate 4.The L plate 5 is turned to the minimum angle with the cutting plate 2, and the saw blade 9 is turned inward to the lowest position, so as to turn into the cutting groove on the cutting plate 2. When the L plate 5 is pushed forward, the bending rod 13 is driven to turn, and then the push plate 1301 is driven to slide on the cutting plate 2, so that the cut workpiece can be pushed inward, which is convenient for taking and improves safety.

[0041] Reference Figure 1 and Figure 5 The adjusting mechanism 10 includes a second motor 1001, and two fixed blocks are fixedly connected to the upper surface of the L-plate 5. The second motor 1001 is fixedly connected to the outer wall of the fixed block. The output end of the second motor 1001 is fixedly connected to a screw rod 1002, and the screw rod 1002 is rotatably set between the two fixed blocks. The outer wall of the screw rod 1002 is threadedly connected to a slider 1003, and the outer wall of the slider 1003 is rotatably connected to a support rod 1005, and one end of the support rod 1005 is rotatably set on the lower surface of the cross plate 7; the adjusting mechanism 10 also includes a slide rail 1004, and the two slide rails 1004 can be symmetrically arranged on both sides of the screw rod 1002, and the slider 1003 is slidably connected between the two slide rails 1004.

[0042] Preferably, when encountering a thicker workpiece during cutting, the second motor 1001 is started to drive the screw 1002 to rotate. The rotation of the screw 1002 can drive the slider 1003 to move left and right. The movement of the slider 1003 can make the support rod 1005 tilt, and then push the cross plate 7 diagonally upward. The movement of the cross plate 7 can drive the first motor 8 and the saw blade 9 to move upward, so that the part of the saw blade 9 exposed on the cutting plate 2 becomes larger, so as to cut workpieces of different thicknesses. When the slider 1003 slides on the outer wall of the screw 1002, the two sides of the slider 1003 slide on the inner wall of the slide rail 1004 respectively, and the slide rail 1004 is provided with a slide groove in the direction of the slider 1003. The height of the slide rail 1004 is higher than the height of the slider 1003, so that the slide rail 1004 can wrap the slider 1003 inside to prevent the slider 1003 from shifting when sliding.

[0046] Preferably, when the cylinder 11 works to push the L-plate 5 to rotate forward, the slide rod 12 arranged on one side of the L-plate will also move accordingly. When the slide rod 12 moves, it can slide along the slide groove opened on the vertical plate 4 to prevent deviation. At the same time, a limit plate is provided at one end of the slide rod 12, and the limit plate is located on the outer side of the vertical plate 4 to prevent the slide rod 12 from falling off the vertical plate 4 when the L-plate 5 rotates.

The upper surface of the tooth column 1403 is fixedly connected to the top plate 3, and the lower surface of the hollow tube 1404 is fixedly connected to the cutting plate 2.

[0048] Preferably, before cutting, the initial position of the tooth column 1403 is at the highest point, so that the interval between the top plate 3 and the cutting plate 2 is maximized, which facilitates the placement of the aluminum alloy door frame and window frame to be cut on the cutting plate 2, and then the drive motor 1401 is started. When the drive motor 1401 is working, it can drive the circular gear 1402 to rotate. When the circular gear 1402 rotates, it can drive the tooth column 1403 in the hollow tube 1404 to move up and down through the hole opened on the hollow tube 1404, and then drive the top plate 3 to move up and down, thereby adjusting the clamping plate 1806 to a suitable position to clamp the workpiece placed on the cutting plate 2, and it can also adapt to aluminum alloy door and window frames of different thicknesses. The height of the clamping plate 1806 is adjusted by this component to adjust the clamping plate 1806 to a suitable position that can completely clamp the aluminum alloy door and window frames, thereby improving the cutting stability.

[0049] Reference Figure 8 A hollow rectangular block is provided on the top plate 3, and a third motor 15 is fixedly connected to the upper surface of the rectangular block. The output end of the third motor 15 is fixedly connected to a first bevel gear 16, and the inner wall of the first bevel gear 16 is meshingly connected to a second bevel gear 17.

A fixed shaft is fixedly connected between the two fixed blocks, and the fixed blocks at both ends of the cylinder 11 are rotatably connected to the outer wall of the fixed shaft.

[0054] Preferably, when the cylinder 11 pushes the L-plate 5 to rotate forward, the position of the cylinder 11 will also rotate accordingly. By setting fixed plates at both ends of the cylinder, the cylinder can rotate on the outer wall of the fixed axis when the L-plate rotates, so that the cylinder can change with the change of the position of the L-plate 5, and the cylinder can push the L-plate 5 to move forward and upward.

[0057] The present invention provides an aluminum alloy door and window frame cutting machine. When the cutting machine is needed to cut aluminum alloy door and window frames, the workpiece to be cut is placed on the cutting plate 2, and then the driving motor 1401 is started. When the driving motor 1401 is working, it can drive the circular gear 1402 to rotate. When the circular gear 1402 rotates, it can drive the tooth column 1403 in the hollow tube 1404 to move up and down through the hole opened on the hollow tube 1404, and then drive the top plate 3 to move up and down, so as to adjust the clamping plate 1806 to a suitable position to clamp the workpiece placed on the cutting plate 2, and then start the servo motor set in the turntable 19 to drive the fixed rod 1801 to rotate.

When the first bevel gear 16 rotates, it drives the second bevel gear 17 to rotate and then drives the turntable 19 to rotate. When the turntable 19 rotates, it drives the clamping mechanism 18 arranged under the turntable 19 to rotate, thereby driving the workpiece fixed by the clamping mechanism 18 to rotate, and sequentially adjusts the position of the workpiece, and then starts the first motor. 8 makes the saw blade 9 start working to cut the workpiece. When encountering a thicker workpiece during cutting, the second motor 1001 is started to drive the screw 1002 to rotate.

When the cross plate 7 moves, the first motor 8 and the saw blade 9 can be driven to move upward, so that the part of the saw blade 9 exposed on the cutting plate 2 becomes larger, so that workpieces of different thicknesses can be cut. If there is a special requirement to adjust the cutting angle, the cylinder 11 set on the bottom plate 1 is started to work. When the cylinder 11 works, it pushes the L plate 5 forward. When the L plate 5 is pushed, the slide bar 12 slides along the slide groove provided on the vertical plate 4. To prevent the L-plate 5 from deviating, the movement of the L-plate 5 can drive the saw blade 9 to swing backward, so that the angle between the saw blade 9 and the cutting plate 2 changes, so that the cutting angle of the saw blade 9 can be adjusted, and the exposed part becomes more, so as to cut workpieces of different thicknesses. If there is a special requirement to adjust the cutting angle, the cylinder 11 arranged on the bottom plate 1 is started to work, and the cylinder 11 pushes the L-plate 5 forward when working. In the process of the L-plate 5 being pushed, the slide bar 12 slides along the slide groove provided on the vertical plate 4 to prevent the L-plate 5 from deviating. When the L-plate 5 moves, it drives the saw blade 9 to swing backward, so that the angle between the saw blade 9 and the cutting plate 2 changes, so that the cutting angle of the saw blade 9 can be adjusted. After the cutting is completed, the cylinder 11 pushes the slide bar 12 to the top of the slide groove on the vertical plate 4.The L plate 5 is turned to the minimum angle with the cutting plate 2, and the saw blade 9 is turned inward to the lowest position, so as to turn into the cutting groove on the cutting plate 2. When the L plate 5 is pushed forward, the bending rod 13 is driven to turn, and then the push plate 1301 is driven to slide on the cutting plate 2, so that the cut workpiece can be pushed inward, which is convenient for taking and improves safety.
