Manufacturing method and structure of non-welded color steel door plate

Abstract

The invention discloses a manufacturing method and structure of a non-welded color steel door plate. The manufacturing method of the non-welded color steel door plate comprises the following steps that 1, a color steel plate after surface treatment is cut according to size and cut into a first color steel plate and a second color steel plate, and cladding excess materials are reserved on the othertwo opposite sides of the first color steel plate and the second color steel plate; 2, clamping-embedded materials are separately bent to form clamping-embedded structures; 3, insulating filling materials are arranged on the inner side of the first color steel plate and / or the second color steel plate; 4, the first color steel plate and the second color steel plate are fixed together through theclamping-embedded structures on the two sides; and 5, the cladding excess materials are bent, the first color steel plate and the second color steel plate are sealed to complete manufacturing of the non-welded color steel door plate. The non-welded color steel door plate is achieved by bonding the filling materials arranged between the first color steel plate and the second color steel plate, after the first color steel plate and the second color steel plate are connected through the filling materials, a door plate structure which can be used directly is formed, and welding is not required.

Description

technical field [0001] The invention relates to the field of door panels, in particular to a manufacturing method and structure of a non-welded color steel door panel. Background technique [0002] A door refers to the entrance and exit of a building or a device that can be opened and closed at the entrance and exit. The door has the function of separating spaces, and it can connect and close the entrances and exits of two or more spaces. [0003] In order to meet the long-term outdoor sleeping needs of construction projects, the color steel prefabricated house is a building that meets the needs of temporary accommodation. It is simple in construction and easy to assemble and disassemble. The color steel door panel is a kind of door panel structure suitable for color steel prefabricated houses. It plays the role of heat preservation by setting fillers such as sponge and wood chips in the door panel. The outer surface of the door panel is made of steel material, which improve...

Problems solved by technology

[0004] In the prior art, the utility model patent with the notification number "CN 205078130U" discloses the usual way of covering the outer surface of the door panel, which fixes the outer surface of the door panel together by welding, and then removes the welding by grinding. seam, and then coat the outer surface with a coating. After the steel plate is purchased, it is necessary to perform processes such as bending, splicing, welding, grinding, and coloring (or electroplating) before the finished product can be obtained. There are too many processes, and the processing cost is relatively high. needs of social development
