The present application also discloses a process for processing an aluminum alloy window frame, comprising the following steps:

S1: Place the frame rod on the workbench 1 so that the axial direction of the frame rod is parallel to the length direction of the workbench 1; and make the cutting position of the frame rod be located at the center of the avoidance hole 14; then start the motor 73, and the motor 73 drives the two clamping blocks 72 to move toward each other to clamp and fix the frame rod;

S2: Rotate the support frame 21, and the support frame 21 drives the cutting assembly 3 to rotate. During the rotation of the cutting assembly 3, observe the indication of the contact between the support frame 21 and the scale 13, so as to quickly adjust the saw disc 33 to the required cutting angle; then rotate the fastener 2112 to fix the support frame 21 and the workbench 1;

S3: Start the second cylinder 81, and the push plate 82 drives the frame rod to move toward the direction close to the saw disk 33. When the cutting position of the frame rod moves to the center of the avoidance hole 14, start the first cylinder 31, and the first cylinder 31 drives the drive box 32 to move toward the direction close to the workbench 1. When the drive box 32 descends, it drives the saw disk 33 to descend to cut the frame rod;

S4: After the cutting is completed, the first cylinder 31 is started, the first cylinder 31 drives the driving box 32 to rise, the driving box 32 drives the saw disc 33 to rise and separate from the frame rods, and then the cut frame rods are collected.

The implementation principle of an aluminum alloy window frame cutting device in an embodiment of the present application is: when working, first place the frame rod between the two clamping blocks 72, and then start the motor 73. The motor 73 drives the bidirectional screw 71 to rotate, so that the two clamping blocks 72 are close to each other. When the clamping block 72 moves to the side wall of the roller 723 and abuts against the frame rod, turn off the motor 73 to clamp the frame rod stably.

Then, according to the cutting angle of the border rod, the support frame 21 is rotated. When the support frame 21 rotates, the cutting assembly 3 is driven to rotate, thereby driving the saw disk 33 to rotate, and the cutting angle of the saw disk 33 to the border rod can be adjusted. During the rotation, the indication of the contact between the support frame 21 and the scale 13 is observed, so as to quickly adjust the saw disk 33 to the required cutting angle. After the adjustment is completed, the support frame 21 and the workbench 1 can be fixed with fasteners 2112.

After adjustment, start the drive box 32, and the drive box 32 drives the saw disk 33 to rotate; at the same time, start the second cylinder 81, and the piston rod of the second cylinder 81 drives the push plate 82 to slide toward the direction close to the cutting component 3. When the push plate 82 slides, it drives the border rod to slide toward the direction close to the cutting component 3. When the border rod slides to the specified position, start the first cylinder 31, and the first cylinder 31 drives the drive box 32 to descend, thereby driving the saw disk 33 to descend to cut the border rod.

During the cutting process, the support plate 4 prevents the frame rod from bending due to the pressure of the saw disk 33; the waste and saw dust generated during the cutting process accumulate on the support plate 4 and the elastic pad 42. At this time, the driving rod 61 is pushed, and the driving rod 61 drives the connecting rod 51 to slide, thereby driving the paddle 52 to move toward the direction close to the elastic pad 42, so that the elastic pad 42 can be compressed, and then the waste and saw dust are cleaned up through the avoidance hole 14; after cleaning, the driving rod 61 is released, and the spring 62 resets to drive the limit ring 511 to move away from the support plate 4, thereby driving the paddle 52 to move away from the elastic pad 42, and the elastic pad 42 resets to fill the gap between the support plate 4 and the side wall of the avoidance hole 14.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
