Abstract

The manufacturing method for an insulation section bar for steel door and window mainly solves the problem of loose bonding of the steel and the plastics due to the rebound of the steel of the cold bending roll method and also the bad heat insulation problem resulted from the using of conductive welding post to connect two steel section bars. Assembling the two steel section bars with a plastic part within and softened the plastic with heat, and pressed the softened plastics to the grooves and holes preserved in the steel section bars, and after cooling down, a new section bar is formed with the steel bars closely connected with the insulation plastics and therefore solves the above mentioned issues. The steel section bars for door and window made in this method is effective in heat insulation, hard in structure and it has high endurance.

Description

Technical field: [0001] The invention relates to a manufacturing method of steel door and window profiles, in particular to a manufacturing method of heat-breaking bridge steel door and window profiles. Background technique: [0002] According to the search, the steel door and window profiles of domestic thermal break bridges are made by cold bending and rolling. The two ends of the plastic connecting plate are respectively inserted into the notch of the steel profile. The invention relates to a method for manufacturing a heat-breaking bridge steel door and window profile that firmly bites together a steel profile and a plastic connecting plate under the action of a horizontal roll and a vertical roll of a composite machine. The disadvantage is that the steel profile has a large elastic modulus and is easy to rebound, so it cannot be tightly combined with the plastic plate. It is known from the industry annual meeting that Swiss JANSEN company adopts the production method ...
