Bending molding process for wooden product solid wood

Abstract

The invention relates to a bending molding process for wooden product solid wood, which is used for solving the bending problems of solid wood, and comprises the following steps: a. blank softening; b. bending molding, in which a protective steel band is attached to one side of the softened solid blank to be placed between an arc molding head of an internal mold and an arc molding surface of an external mold, and the arc molding surface consists of two split modules, the internal mold moves towards the solid wood blank and exerts force on the solid wood blank, and simultaneously back pressure is exerted at the other side of the solid wood blank by a jacking block; the two split modules bend and deform along the solid wood blank and take the hinge point as the center of a circle to rotate naturally so as to gradually clutch the solid wood blank until the solid wood blank is bent and molded; and c. stripping drying. The invention eliminates the solid wood longitudinal compression process, and has simple process and low production cost; the solid wood does not need to be softened by a chemical softener before bending, and the production processes are environmentally friendly; the structures of the solid wood bending internal mold and external mold are simple, the design is reasonable, the molding is rapid, the force exerting is balanced, and the quality of products is stable and reliable.

Description

technical field [0001] The invention relates to a wood product processing method, in particular to a solid wood bending molding process for bending solid wood into a U shape or other arc shapes, and belongs to the technical field of wood product processing. Background technique [0002] Solid wood products are natural, rustic, and environmentally friendly. Using them to make various furniture, office facilities, and decorative items has advantages that other materials cannot replace. With the continuous improvement of people's living standards and aesthetic concepts, the market demand and quality requirements for solid wood products are also increasing, and various processing methods and equipment for making solid wood products have emerged as the times require. At present, the process of bending solid wood into U-shaped or arc-shaped generally adopts the following two methods: one is compressed wood cold-bending technology, after the wood is softened with steam, it is first...

AI Technical Summary

Problems solved by technology

At present, the process of bending solid wood into U-shaped or arc-shaped generally adopts the following two methods: one is compressed wood cold-bending technology, after the wood is softened with steam, it is first compressed along the grain, then cold-formed, and finally dried and set , this method has a long process and high production cost; the other is to use a wood softener to chemically soften the wood, and then bend and dry it. This method has the disadvantages of using chemical softeners to the production environment. problem of influence

In addition, the current common solid wood bending equipment has problems such as complex structure and high equipment investment
