[0002] With the development of the times and the progress of industry, the types of materials for doors and windows are becoming more and more diverse. Compared with wooden doors and windows in the past, aluminum-plastic alloy doors and windows are stronger and more beautiful in appearance. When processing and making aluminum-plastic alloy doors and windows, cutting equipment is required for cutting operations.

[0003] Announcement No. CN 215468394 U discloses a door and window sash material cutting device, which uses an AC drive motor to drive a screw rod to rotate. Since the screw rod is threadedly connected to the threaded hole of a slider, the rotation of the screw rod can drive the slider to slide on the outer surface of a support frame, thereby driving the cutting blade to move up and down, effectively replacing the current hand-pressure cutting method, effectively improving the cutting efficiency, and reducing the labor intensity of workers; the cutting angle of the cutting blade is adjusted by rotating the linkage shaft, and during the adjustment process, it can be conveniently adjusted through a pointer and a dial, effectively improving the practicality of the cutting device.

[0004] However, there are some defects in the above scheme; in the above scheme, when cutting the door and window sash materials, it is necessary to manually press the door and window sash materials with hands to fix them, which makes the door and window sash materials not stable and safe during the cutting process, and the adjusted angle is limited by adjusting the bolts, but the vibration of the driving motor during operation may cause it to loosen, thereby affecting the cutting angle.

[0040] The utility model further provides a door and window material cutting machine including the above-mentioned clamping mechanism.

[0041] The clamping mechanism and the door and window material cutting machine work as follows: when in use, the door and window material to be cut is placed under the L-shaped plate 210 on the top of the support platform 110, and the pressure plate 230 is pushed by starting the hydraulic cylinder 220 to press and fix the door and window material.

The cutting motor in the cutting tool 170 drives the cutting blade to rotate at a high speed to cut the door and window materials. At the same time, the positioning clamp rod 160 can be pulled out of the positioning groove 131 as needed, and the positioning clamp rod 160 is rotated to drive the rotating shaft 140 to rotate. The rotating shaft 140 drives the cutting tool 170 to rotate and adjust the cutting angle, and then the positioning clamp rod 160 is released, and the elastic action of the spring 152 is used to push the limiting ring 153, so that the limiting ring 153 drives the positioning clamp rod 160 to insert into the positioning groove 131 for positioning without other human action, and the vibration during the cutting process will not cause the positioning clamp rod 160 to separate from the positioning groove 131, and the limiting method is stable.

[0042] It should be noted that the specific models and specifications of the cutting motor, the drive motor 123 and the hydraulic cylinder 220 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] The power supply and principles of the cutting motor, the driving motor 123 and the hydraulic cylinder 220 are clear to those skilled in the art and will not be described in detail herein.
