[0002] Doors and windows are one of the main building window and door products in my country. They are primarily composed of aluminum-plastic frames, moldings, and flat glass. Moldings are strips of material used to secure and seal door and window glass. They play a key role in door and window installation. In addition to firmly securing the glass, they also seal the gap between the door and window and the frame, preventing the infiltration of rainwater, dust, and other foreign matter, thereby maintaining indoor comfort and dryness.
[0003] Beadings need to be cut to fit the dimensions of doors and windows, often using a beading cutting device. Existing beading cutting devices often use a motor to drive the blades to rotate and cut the beadings, with a fixed cutting angle. However, beading cutting can involve not only right-angle cutting but also bevel cutting, making it difficult for workers to adjust the blade angle according to cutting requirements, thus affecting beading cutting efficiency.
