Prepare solid wood, according to the shape in space between the kink of adjacent flex woody part part, solid wood is cut, form solid wood connector, at solid wood connector surface coated with adhesive;
2) the multi-layer sheet veneer after superimposed is put into mould, use hot-press equipment pressing mold, multi-layer sheet veneer is carried out to precompressed, after space forms, the solid wood connector that is coated with binding agent is put into space and carry out overall pressing, taking-up cooling after pressing completes.
Step 1) in, the thickness of multi-layer sheet veneer is 1.3mm～1.7mm;
The drying and processing process of multi-layer sheet veneer is as follows,
(1) be 170 DEG C～190 DEG C by dryer Temperature Setting, air pressure reaches 0.2Mpa～0.3Mpa;
(2) the multi-layer sheet veneer of completing is sent into dryer, veneer number of pages is no more than 3 pages;
(3) multi-layer sheet veneer is dried, drying time is 25min～30min, and making Veneer moisture is 7%～8%, and the veneer heat radiation after oven dry is stand-by;
Bonding agent comprises glue and ammonium chloride, and its proportioning is 1000:3～1000:5.
The utility model has the advantage of, this furniture adds solid wood connector to cushion at the crucial stress point of bending-wood parts, slows down the force intensity that is subject to of wooden hide fiber, is convenient to carry out moulding, break through the physics moulding limit of bentwood furniture, and retain the environmental protection characteristic of bentwood furniture, by this multi-layer sheet and solid wood in conjunction with formative technology, the multiple parts of mould molding, make production efficiency increase at double, production cost is significantly declined, and makes product form more graceful, and firmness is more reliable.

Material is prepared
Multi-layer sheet veneer: can select poplar, Eucalyptus, birch veneer according to product requirement, THICKNESS CONTROL is at 1.3mm～1.7mm, and thickness exceedes this upper limit and easily produces fiber drawing crack phenomenon.Veneer is because native annulus is cut into slices and had many flaws or size is incomplete, should first mend plate and spell skin with material saving making before multi-layer sheet; Spell Pi Shiyao and accomplish that wood grain is complete, symmetrical, color is basically identical, panel immaculate, without knot, flawless, nothing is gone mouldy, wood grain is clear.
Solid wood connector: can select weedtree or birch timber, make the 75mm length of side, the triangle wooden unit of both sides band R50 radian with band saw.This solid wood connector should select without knot, flawless, without the producing wood that goes mouldy, and through normal stifling processing.
Binding agent: the proportioning of glue and ammonium chloride is 1000:3～1000:5, can allocate suitable flour if desired into, to increase bond effect.
Compacting tool set design: the pressing direction that this seat relates to is respectively front side, upside, rear side, downside, owing to not having parts to intercept between front side, upside, the front side of mould and upper portion can be integrated, therefore, compacting tool set is made up of patrix, rear mold and counterdie, utilizes the upper and lower pressure in hot press front and back pressing multi-layer sheet veneer and solid wood connector simultaneously.
Process
Drying-plate: be 180 DEG C by dryer Temperature Setting, air pressure reaches 0.25Mpa; The multi-layer sheet veneer of completing is sent into dryer, and veneer number of pages is no more than 3 pages, and will place neat; Veneer is dried, and drying time is 25min～30min, and making Veneer moisture is 7%～8%, the veneer after oven dry be placed on heat radiation rack, dispel the heat stand-by.
Cutting plate: according to shape of product, quantity and material, veneer is cut; In cutting process, good outward appearance veneer is chosen for panel, panel select requirement: without cracking, without dying for the sake of honour, anophthalmia hole and smooth surface, leftover pieces more than 2cm will utilize to reduce spillage of material again.
Gluing: debugging rubber roll: adjust rubber roll thickness according to the thickness of institute's processing work; Adjust glue amount, the glue that tune is mixed is evenly poured between two rubber rolls; Veneer is put between rubber roll and to be crossed glue, and crossing glue should not many mistake, should notice that gluing is even, has to leak phenomenon and can carry out craft benefit glue, need avoid hot plate to cross glue.
Lamination: owing to relating to solid wood and multi-layer sheet is one-body molded, the lamination process need of this seat carries out respectively stacking multilayer boards to front support leg, rear leg and lower support leg.In lamination process, size will meet the requirements, and can not have overlapping, vacancy, and breach, the available wooden skin in eye place are repaired, and should note wooden skin positive and negative and wooden ridge orientation while pasting wooden skin, keeps wooden skin clean, glue-free washmarking mark.
Patrix: whether accurately check institute's die pressing product model, specification, board dimension, number of pages; Start hot press, mould is put to seat in the plane; The veneer of folding is put into mould, and measures its thickness, start hot press, first by two to touching tool pre-pressing, until in the middle of form behind space, the solid wood connector of gluing is put into space, then the rear side multilayer single plate workpiece of folding is entered to mould, carry out overall pressing.
Unload and touch: pressing, after 25 minutes, is closed hot press, take out the good workpiece of pressing and cool, 15 minutes and its cold true deformation coefficient of inspection, finish whole pressing process as qualified.
This moulding process adopts solid wood and the pattern of multi-layer sheet connecting shaping to produce furniture critical piece, and practice shows, improving productivity is to the more than 3 times of old technique, and artificial demand has but declined 50%, and materials'use reduction by 20%.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
