[0022] At the same time, two cylinders 7 are fixedly connected to the upper surface of the bottom plate 1, and the bottom plate 1 is slidably connected to a plate-shaped support plate 8 through the two cylinders 7, and two plate-shaped connecting plates 9 are fixedly connected to the lower surface of the support plate 8. The opposite side surfaces of the two connecting plates 9 are rotatably connected to a disc-shaped cutting disk 10 through a rotating shaft, and one end of the rotating shaft penetrates the connecting plate 9 to its side surface and is fixedly connected to the output end of the motor, so that the support plate 8 is driven to move downward under the action of the two cylinders 7, thereby driving the connecting plate 9 and the cutting disk 10 to move downward, and the cutting disk 10 is driven by the motor to rotate in height, so as to cut the door and window profiles below; secondly, the cutting disk 10 is located on the lower surface of the support plate 8 Several telescopic columns 11 are fixedly connected on both sides of the support plate 8, and the support plate 8 is slidably connected to two plate-shaped pressing plates 12 through the several telescopic columns 11. The lower surface of the support plate 8 is located outside the several telescopic columns 11 and is fixedly connected with return springs 13, and the lower ends of the several return springs 13 are fixedly connected to the upper surfaces of the two pressing plates 12, so that in the process of the support plate 8 moving downward, the pressing plate 12 first contacts the profile, and then the cutting disc 10 contacts the profile to cut it. Under the telescopic effect of the telescopic column 11 and the rebound effect of the return spring 13, the pressing plate 12 is driven to press the two ends of the profile to be cut, thereby maintaining the stability of the profile during the cutting process and avoiding the two sections of the profile from warping after the cutting is completed.

[0023] Reference Figure 2A groove-shaped first slide groove 14 is provided on the upper surface of the rotating plate 2, and a screw rod 15 is rotatably connected to the inner wall of the first slide groove 14. The outer surface of the screw rod 15 is screwed and connected to the movable plate 4 through a ball screw, so that when it is necessary to clamp profiles of different lengths, the staff rotates the screw rod 15 to drive the movable plate 4 to slide under the action of the ball screw, thereby driving the two clamping plates 5 to slide, so as to be suitable for clamping profiles of different lengths;

[0024] Secondly, a groove-shaped second slide groove 16 is opened on the upper surface of the fixed plate 3 and the movable plate 4, and a stud 17 is rotatably connected to the inner wall of the second slide groove 16. The outer surface of the stud 17 is screwed together with the two clamping plates 5 through a ball screw, and one end of the two studs 17 respectively penetrates the side surfaces of the fixed plate 3 and the movable plate 4, and is fixedly connected to the output end of the motor, so that the stud 17 can be driven to rotate by the motor, thereby driving the two clamping plates 5 to slide relative to each other under the action of the ball screw, so as to stably clamp profiles with different cross-sectional sizes, so as to stably cut them and improve the cutting efficiency and quality.

When it is necessary to adjust the cutting angle of the profile, the limiting block 20 is pressed so that the limiting block 20 slides on the inner wall of the limiting groove 19, and the spring is in a compressed state. Then, the rotating plate 2 is rotated by a certain angle, and then the limiting block 20 rebounds and engages with the inner wall of the corresponding groove 18 under the resetting action of the spring, thereby completing the adjustment of the angle of the profile, which is convenient for multi-angle cutting.

[0026] The implementation principle of a door and window profile cutting device in an embodiment of the present application is as follows: a worker rotates the screw 15, thereby driving the movable plate 4 to slide under the action of the ball screw, so that it can be suitable for profiles of different lengths, and then the door and window profile is placed on the upper surface of the movable plate 4, the two placement blocks 6, and the fixed plate 3, and then the double-headed stud 17 is driven by the motor to rotate, thereby driving the two clamping plates 5 to slide relative to each other under the action of the ball screw, so that profiles of different cross-sectional sizes can be stably clamped, and then the limit block 20 is pressed to make the limit block 20 slide on the inner wall of the limit groove 19, and the spring is in a compressed state, and then the rotating plate 2 is rotated a certain angle according to the cutting requirements, and then the limit block 20 Under the restoring action of the spring, it rebounds and engages with the inner wall of the corresponding groove 18, thereby completing the adjustment of the angle of the profile so as to perform cutting at any angle. Subsequently, the support plate 8 is driven downward by the action of the two cylinders 7. During the downward movement of the support plate 8, the pressure plate 12 first contacts the profile, and under the telescopic action of the telescopic column 11 and the rebound action of the reset spring 13, the pressure plate 12 is driven to press the two ends of the profile to be cut, thereby maintaining the stability of the profile during the cutting process. Then the cutting disk 10 contacts the profile, and the cutting disk 10 is driven by the motor to rotate in height so as to cut the profile, thereby completing stable cutting of the profile at any angle, thereby improving the versatility and practicality of the device.
