Description

Wood molding method capable of realizing three-dimensional curved surfaces {WOOD MOLDING METHOD THAT CAN REALIZE THREE-DIMENSIONAL CURVED SURFACE}

The following embodiments relate to a wood molding method capable of implementing a three-dimensional curved surface in which a tree is molded/processed to include a three-dimensional curved surface in order to manufacture a wooden structure (including furniture) having a curved surface in an egg direction.

Wood is a necessary material for the furniture industry, construction industry, landscaping industry, and environmental industry. Recently, among the above woods, synthetic wood having advantages such as durability, workability, maintenance, and aesthetic effect is widely used. In addition, more recently, synthetic wood having a hollow structure has been widely used because of its easy processability.

Recently, the demand for utilizing wood structures for furniture, interior/exterior decorations, etc. is increasing, and in particular, the preference for sleek and aesthetic products, unlike mass-produced products, is increasing.

In order to manufacture a wood structure with aesthetics, processing into such a three-dimensional egg-direction curved surface is required, but according to conventional wood processing methods, it is almost impossible to process wood into a structure having a three-dimensional three-dimensional curved surface.

Conventionally, processing methods such as attaching a wood-shaped film to the surface of a three-dimensional structure such as plastic to give a 'feel' of wood or steaming a thin wooden board in a bent state to realize a curved surface have been utilized.

As described above, in the curved wood technique of processing a curved surface by steaming wood, it can only be bent in one direction according to the 'grain' of the wood material, so only products with a thin thickness such as chairs and tables can be molded, and the curved direction is three-dimensional There was a limit that it was not possible to mold a product with a beautiful aesthetic because it was limited to a two-dimensional curve rather than a curved surface.
