Description

Bentwood furniture and preparation method thereof

The present invention relates to furniture and making thereof, especially a kind of Bentwood furniture and preparation method thereof.

Publication number is that CN1216728A discloses a kind of " preparation method of composite type bent wood furniture ", this method is to make required furniture bending part matrix with the multilayer planar glued board by the sweep-saw segmentation method, the decorative layer of being made up of timber section or veneer at surface coverage one deck of furniture bending part matrix.Wherein the timber section covers on the curved surface of furniture bending part matrix, and veneer covers on the side of furniture bending part matrix, bonds together by adhesive between the surface of timber section, veneer and furniture bending part matrix.Other parts of the furniture bending part made and furniture are fitted together just obtained the good composite type bent wood furniture of a kind of texture.But have the following disadvantages with said method Hepplewhite bending part: (one) is though its edge cuts of so-called bending part becomes curved surface and the centre also can regged sky, but these parts still are one flat plate on the whole, just the edge has curved surface, as the disclosed headpiece accompanying drawing of above-mentioned patent application, and can not realize multi-direction bending, reason is because the multilayer planar glued board is to be composited by the plane glued board that the polylith lines intersects, and in order to improve stock utilization, also carry out the fritter splicing in inside, and the multi-layer sheet of this structure can not carry out multi-direction bending, the inconsistent glued board of lines not only checks and balance not flexible, and lines and the inconsistent glued board of bending direction break easily; (2) the bending part matrix is made with the sweep-saw segmentation method, and this technology is taken material, and the parts of particularly big to some sizes, intermediate hollow adopt the way of segmentation splicing sometimes for material-saving, and then technology is too complicated again; (3) section of matrix surface covering timber or veneer are made decorative layer, and not only complex process and wood grain are discontinuous.

The purpose of this invention is to provide a kind of draw materials wide, stock utilization is high, not only have curved surface shape profile, also can make the preparation method of the Bentwood furniture that side multi-direction bending, bending strength height, surface grain attractive in appearancely link up, manufacture craft is simple.

The objective of the invention is to be achieved through the following technical solutions: this bentwood furniture be characterised in that bent member be outline and middle part vacancy have curved surface, its side is the multilayer composite of multi-direction bending.

The preparation method of Bentwood furniture is:

1) obtains to leave allowance, unified rift grain direction, as to set splicing length vertical bar sheet spare with 1.0～4.0 millimeters veneer by dashing, cutting;

2) the vertical bar sheet spare that will scribble viscose glue along clockwise (or counterclockwise) direction is combined into multi-plywood according to the pattern stack that marks on the base plate, and its seam of the sheet spare of compound tense adjacent layer staggers, and the superiors cover the monoblock panel;

3) with mould with the multilayer composite hot pressing after compound or be cold-pressed into flat shape or the side is the shape of multi-direction bending;

4) hollow out along impression earlier, under the guiding of model pattern, cut then and allowance removed the back obtains to have within the curved surface, the bent member that the pressure layer is clear, gummed is solid of outline by curve milling, sand with the base plate and the panel of icking tool with upper and lower covering.

Also can topped again one deck woodgrained paper on described bent member, spray treatment is carried out on the surface of woodgrained paper again, just can obtain to have the bending-wood member of wood grain style.

Advantage and good effect that the present invention is compared with prior art had are: draw materials wide, stock utilization is high, reduced cost, not only have curved inside and outside profile, also can make the side multi-direction bending, the preparation method of the Bentwood furniture that bending strength height, surface grain be attractive in appearance to link up, manufacture craft is simple.

Below by embodiment and contrast accompanying drawing the present invention will be described:

Fig. 1 is the stereogram of one embodiment of the invention.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is the front view after this embodiment of the invention is covered with woodgrained paper.

Fig. 4 is the B-B cutaway view of Fig. 3.

The structure chart of base base at the bottom of Fig. 5 is this embodiment of the invention, when panel does not hollow out.
