Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter door production equipment, in particular to a heat-insulating rolling shutter door guide rail cutting device. Background Art

[0002] Rolling shutter doors are made of multi-jointed door slats connected in series. In a fixed slide, the door moves up and down with the reel above the door as the center. Rolling shutter doors are commonly used in shops and play the role of horizontal partitions like walls. The thermal insulation effect of rolling shutter doors is achieved through the design of the internal structure. Usually, the internal structure of rolling shutter doors is composed of double-layer steel plates and thermal insulation materials. The double-layer steel plates have thermal insulation effects and can also strengthen the strength of the door body and improve the overall performance of the door body. The thermal insulation material is mainly polyurethane foam, which has a high density and a low thermal conductivity. It can effectively prevent the internal and external heat transfer of the door body and improve the thermal insulation effect of the door body. In addition, the thermal insulation rolling shutter door needs to have a corresponding guide rail to ensure the stable limit of the rolling shutter door when rolling up and unfolding. Figure 4 The figure shows a schematic diagram of an existing universal guide rail, which is made of a metal plate through processes such as stamping and bending. It has a hollow cavity with an opening on one side. After processing and forming, the guide rail needs to be cut into a certain length according to usage requirements. However, in the process of cutting by cutting, due to the lack of support in the internal cavity of the guide rail, it is easy to deform when subjected to external force, causing the guide rail cut to not meet the requirements, affecting subsequent use. Based on the above problems, a thermal insulation rolling shutter door guide rail cutting device is proposed. Utility Model Content
