A kind of solid wood multi-layer board bending back manufacturing method

Abstract

The invention discloses a manufacturing method of a solid wood composite board bent backrest. The manufacturing method comprises the steps that a solid wood board is sawed into veneers used for manufacturing the bent backrest; the two faces of each veneer are sanded through a wide-band determined-thickness sanding machine; the two faces of the veneer serving as a core material are coated with laminating glue through roller painting; the veneers are stacked; the outer surfaces of the two veneers serving as surface layers are wiped wet with wet cloth, and the inner surfaces of the two veneers are coated with laminating glue through roller painting; the veneers are stacked with the inner surfaces facing the core material, so that a prefabricated composite board is formed; the multiple prefabricated boards are pressed into the bent backrest on a cold press. According to the manufacturing method of the solid wood composite board bent backrest, a traditional bent backrest processing method is changed, a whole solid wood material does not need to be consumed, the number of manufacturing procedures is reduced, wood materials are saved, and the manufacturing cost is reduced; an upper die tool and a lower die tool which are reasonable in structure are arranged on a cold press body, dies are made of wood, the malleability of the dies is identical to that of the solid wood composite board, the problems of fracture and the like under the condition of multi-layer cold pressing are solved, the wood grains are smooth after the bent backrest is formed, the ground color is clear after oil paint is painted, and the appearance is more beautiful.

Description

technical field [0001] The invention relates to a method for making a curved back, in particular to a method for making a curved back of a solid wood multilayer board. Background technique [0002] In the furniture industry, for the sake of aesthetics and comfort, most solid wood furniture requires curved backrests, such as: curved backs for seats, curved backs for beds, etc. Most of the existing curved back production uses a whole piece of solid wood. It needs to go through batching, cutting and bending, gluing, milling, etc. The process increases, the front of each process is elongated, waste of materials, high cost, and cycle time Long; the most important thing is that due to the splicing of wide boards, there are many seams, there are horizontal marks, the wood grain is not smooth, the color is different, and the standing stubble will bring great change to the paint, the background color is not clear, and it will affect the appearance.

Problems solved by technology

Most of the existing curved back production uses a whole piece of solid wood. It needs to go through batching, cutting and bending, gluing, milling, etc. The process increases, the front of each process is elongated, waste of materials, high cost, and cycle time Long; the most important thing is that due to the splicing of wide boards, there are many seams, there are horizontal marks, the wood grain is not smooth, the color is different, and the standing stubble will bring great change to the paint, the background color is not clear, and it will affect the appearance. Meet customer requirements; the existing cold presses are all aimed at metal plates or single-layer veneer, because the ductility of solid wood veneer is not as good as the toughness of single skin, it is not possible to directly cold press and bend multi-layer solid wood veneer, direct cold press bend will break
