Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing equipment, in particular to a bending device for aluminum alloy door and window profiles. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and sashes, referred to as aluminum doors and windows. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of load-bearing rods (rods that bear and transmit deadweight and loads) and doors and windows composited with wood and plastic, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows.

[0003] At present, when processing aluminum alloy doors and windows, it is necessary to bend the aluminum alloy profiles. Most of the existing aluminum profile bending devices use a bending knife to press down to bend the profile. When the blade is pressing down, it is very easy to scratch the surface of the profile, thereby affecting the appearance of the processed profile.

[0004] Therefore, in recent years, a bending device has gradually appeared on the market that can bend the profile by positioning one end and fixing the other end of the profile. Although this avoids the scratches on the profile surface caused by the bending knife, the chamfer radius of the bending part of the bending equipment is fixed, resulting in limited types of aluminum profile processing. At the same time, the chamfer of the bending part is easily worn by the friction of the workpiece. Over time, the wear and tear increases, and the chamfer becomes larger and larger, which easily affects the accuracy of the bending radius of the profile and affects the processing quality of the profile.
