Edge folding tool for front top light support of automotive trim ceiling

Abstract

The invention particularly relates to an edge folding tool for a front top light support of an automotive trim ceiling. The edge folding device comprises a ceiling support, a base and a push plate, wherein the upper part of the base is provided with a shaping module and an edge folding module, and the two sides of the base are provided with ejection modules; the push plate can penetrate through the base and reciprocate vertically; the shaping module is arranged in a ring-shaped mode; the number of the edge folding modules is the same as that of folded edges of the support, and each edge folding module comprises a connecting block, connecting rods and a pressing block which are sequentially hinged; and each pressing block is arranged in a V shape, the bending parts of the pressing blocks are hinged to the shaping module, one side of the bending part of each pressing block serves as a connecting part, the other side of each pressing block serves as a turning folding part, and each turning folding part is hinged to the connecting rods; the connecting blocks are fixedly connected with the push plate; and each ejection module is provided with a second clamping groove, and the ejection modules can reciprocate in the vertical direction. The edge folding tool for the front top light support of the automotive trim ceiling has the advantages that the assembly success rate is high, and the requirement for precision of a metal support is not high.

Description

technical field [0001] The invention relates to a hemming tool for an automobile ceiling, in particular to a hemming tool for a front dome light bracket of an automobile interior decoration ceiling. Background technique [0002] Commonly used metal brackets for headlights on ceilings in automotive interiors require fixed connection and assembly of the metal frame 1 and the ceiling body 2 . The inner edge of the metal frame is vertically provided with a plurality of folds 3 , and after the folds are turned 90°, the ceiling body is clamped between the folds and the metal frame, so that the metal frame 1 is fastened to the ceiling body 2 . At present, the assembly mold of the metal bracket of the ceiling headlight of the automobile interior is composed of accessories such as a base frame, upper and lower molds, cylinders, guide posts and guide sleeves. The upper mold of the mold is driven by the cylinder to press down, and the mold bends and deforms the connection between the ...

Problems solved by technology

However, in the process of use, it is found that the hemming tooling of this method must be completely corresponding to the position of the mold during assembly, so that the hemming can be successfully folded, that is to say, the height of the metal frame and the mold must be matched. Therefore, not only the precision of the guide device of the mold and tooling is high, but the metal frame itself must also have high precision; it also puts forward high requirements for the operator's proficiency in operation, otherwise it will be easy during the assembly process of the metal frame. The hemming position of the bracket cannot be deformed as expected, so that the frame cannot be fastened to the ceiling body, causing the frame to be scrapped; it may even damage the ceiling body, causing greater losses

Moreover, in the prior art for the assembly mold of the metal bracket of the ceiling headlight of the automobile interior, one assembly mold can only be bent for the metal frame 1 of the same type and size, and if the mold is partially worn, it needs to be replaced as a whole, and the use cost high
