Description

Technical Field

[0001] The utility model belongs to the field of aluminum alloy door and window profile processing, in particular to an aluminum alloy door and window profile cutting machine. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows with aluminum alloy as load-bearing rods and substrates and wood and plastic composites, or aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw aluminum profiles, the surface treatment of aluminum and the internal processing quality, and the price of aluminum alloy doors and windows. The existing plastic-steel door and window cutting device does not have a special fixing mechanism, and workers are required to hold the plastic-steel door and window profiles by hand. The National Intellectual Property Administration issued an authorization announcement on March 17, 2023, with an authorization announcement number of CN218638698U: "A kind of aluminum alloy door and window profile cutting machine". The patent discloses a device for cutting aluminum alloy door and window profiles, but the device can only cut profiles of 45 degrees and 90 degrees, and cannot cut profiles at any angle.
