The present invention relates to an apparatus for producing a door and window frame and a bent metal product, wherein a set of forming rolls for forming the door and window frame and the bent metal product are constituted by upper and lower surface support rollers, left and right side surface support rollers, and forming rollers. The upper and lower surface support rollers and the left and right side surface support rollers apply uniform physical force to a panel to prevent reaction caused by the forming rolls, and thus the panel is bent while basically being prevented from being corrugated while passing through the set of forming rolls. The apparatus comprises: upper and lower support rollers arranged on upper and lower surfaces of a panel such that the upper and lower support rollers tightly contact the panel to support the upper and lower surfaces of the panel; left and right side surface support rollers arranged on left and right side surfaces of the panel such that the left and right side surface support rollers tightly contact the panel to support the left and right side surfaces of the panel; and cylindrical foldable forming rollers arranged on the upper and lower surfaces or side surfaces of the panel, and bent at a predetermined angle, such that the forming rollers tightly contact the panel to bend the panel under uniform pressure, thus basically preventing the panel from being corrugated during forming.
Description
technical field [0001] The invention relates to a door and window frame and metal bending parts manufacturing device, in particular to a forming roller set for forming door and window frames and metal bending parts, which is composed of upper and lower support rollers, left and right side support rollers and forming rollers. And prevent the reaction force of the forming rollers on the sheet when the upper and lower support rollers and the left and right side support rollers are supporting the sheet, so as to fundamentally eliminate the door and window frames and metal bending parts that have corrugated on the sheet passing through the forming roller kit Make device. Background technique [0002] Generally, heat insulation windows have heat insulation and sound insulation functions, and are widely used in ordinary houses, shops, apartments, offices, etc., and their materials are aluminum or PVC, etc., and they are connected by a fixed frame fixed on the wall and a hinge. The...
