Problems solved by technology

In this way, when the steel plate is cold-rolled and formed, because the rollers are affected by the space occupied by the middle core material, the two sides of the steel plate can only be cold-bent into a simple back-shaped structure. This structure leads to a small increase in the strength of the steel plate after cold-bending, and The interface of the sandwich panel is simple during installation and splicing, and the airtightness is poor

Embodiment

[0024] Such as figure 2 As shown, it is a schematic structural diagram of a device for gluing steel plates for color steel sandwich panels. The gluing device consists of a first feed pipe 12, a second feed pipe 13, a glue outlet pipe 14, a steering mechanism 15, a bracket 16 and a cylinder 17 compositions.

[0025] The first feed pipe 12, the second feed pipe 13 are installed side by side on the support 16, the steering mechanism 15 is connected with the first feed pipe 12, the second feed pipe 13 respectively, the cylinder 17 is installed on the support 16, and The cylinder 17 is connected with the steering mechanism 15, and the glue application pipe 14 is evenly fixed on the first feed pipe 12 and the second feed pipe 13 by screws.

[0026] A manufacturing process of a metal heat-insulating sandwich panel is as follows:

[0027] In the first step, the upper steel plate 1 and the lower steel plate 7 are cut off by the color steel coil cutting device 2 in the same direction...

Abstract

The invention relates to a process for manufacturing an insulated metal laminboard. The process is characterized in that a method comprises the following steps: a glue coating device for a steel plate is arranged on an insulated metal laminboard compounding machine set; firstly, an upper steel plate and a lower steel plate are subjected to cold rolling and molding by a cold rolling machine; secondly, glue is coated on the upper steel plate and the lower steel plate by the glue coating device for the steel plate of the insulated metal laminboard compounding machine set; and finally the upper steel plate and the lower steel plate are compounded with a heat insulation core material by the insulated metal laminboard compounding machine set to form the laminboard. The process has the advantages of improving the strength of the steel plate and the composite strength of the laminboard after the final molding, the sealing performance of a joint when the laminboards are spliced and the heat insulation performance of a color steel laminboard.

Description

technical field [0001] The invention relates to a manufacturing process of a metal heat-insulating sandwich panel, which is used for coating polyurethane glue on the color steel sandwich panel before the color steel panel is combined with the core material, and belongs to the technical field of composite manufacturing of the sandwich panel. Background technique [0002] At present, most of the color steel sandwich panels produced are made of polystyrene foam board or rock wool as the core material and color coated steel plate. In the production process, the color steel plate and polystyrene foam board or rock wool are combined with polyurethane The glue is compounded to form a color steel sandwich panel. The traditional sandwich panel composite manufacturing process is as follows figure 1 shown. Its method is: [0003] In the first step, the upper steel plate 1 and the lower steel plate 7 are cut by the color steel coil cutting device 2 and then grooved by the steel plate ...
