Abstract

The invention discloses a kind of method for production of large-scale timber structure veneer products, it is suitable for manufacturing various Large Size Special Shaped handicrafts and sand table based article.Be characterized in manufacturing earlier unpainted clay idol, and make according to this unpainted clay idol and can piece together the plaster mold of tearing open, on the plaster mold of dried post-coat lacquer combination, paste little plank piece, form its body, then in body surface lagging, bottoming, colouring, mopping, be equipped with the goods that engraving or kneading ornament can be made into various of an antique style, exquisite elegances.This method saving of labor, material-saving reduce labor intensity, and be fit to produce in enormous quantities, and goods are firm does not also produce deflection deformation.

Description

The method for production of veneer products for large-size wood structure

The present invention relates to the method for production of the method for production of handicraft, particularly veneer products for large-size wood structure.

At present, the timber structure handicraft normally adopts whole high-quality timber Carving Machining to be shaped, and this method expense of taking a lot of work expects, and is high to workman's specification requirement, and can only single-piece production, can not adapt to the needs of mass industrialized production.Also adopt wood-turning machine processing for small size cylindrical shape or shallow article, but for large scale because the timber waste is serious, and the grain of wood destroys, and causes deflection deformation, processing is restricted.In recent years, people are seeking the new way that solves this difficulty always.

The object of the present invention is to provide a kind of method for production of veneer products for large-size wood structure.This method only needs can make firm fineness with leftover bits and pieces, indeformable again handicraft.

The present invention is achieved in that we at first merotomize the complete satisfactory unpainted clay idol of size shape, can be easy to the demoulding for well from the goods body with plaster mold, each part is as the die joint of perfusion plaster mold, sequence number on the volume, pour into out each part plaster mold successively, shaping has been pieced together in the half-dried back of taking off, and makes it reach the requirement size, does back varnish coating or mixed paint.During use, in order number mould preparation combination and fixing, on its die face, by amount of curvature, closely paste the different shape that meets the goods body thickness and require, the little plank piece of leftover bits and pieces that differs in size, the gap is the smaller the better between each piece, all sticks and treats to remove plaster mold after glue is done, and forms the body of required goods.Is best with various wooden viscose glues with 4115 glue water-resistance at body surface, sticks the ornament such as fruit stone, shell of desired thickness.At last on the lagging surface, add glue with talcum powder and add desired coloured pigment and mix the back bottoming, each little plank gap is filled and led up, the colouring back gets final product for 3-5 time with the Polyurethane painting brush.According to the shape difference, plaster mold can be an internal mold, also can be external mold.For the complicated situation about can't resolve of profile with internal mold or external mold; can resolve into several sections to the goods profile; make each part with said method, with 4115 glue ready-made decomposer is gluedd joint into an integral body then, the special-shaped timber structure goods of virtually any size all can be manufactured like this.This method does not need high-quality timber, and labor and material saving is to manufacture large-size wood structure lagging handicraft perfect method, thereby has reached purpose of the present invention.

Below with reference to drawings and Examples the present invention is done and to describe in further detail.

Fig. 1 is the schematic diagram of a kind of concrete grammar step of the present invention.

With reference to Fig. 1, manufacture a φ a500 * H400 millimeter, thick 20 millimeters of timber structure body, manufacturing of the interwined dragon incense burner body of 10 millimeters Cortex walnut laggings of outer surface is as follows:

It is similar to design incense burner body to manufacture shape with wood powder, mud, the husky tabia that mixes, and is of a size of the unpainted clay idol (1) of φ b400 * h350 millimeter, and giving and doing plaster mold thickness is 20 millimeters.The unpainted clay idol furnace bottom is divided into eight parts last from top to bottom along circumference, and φ c100 millimeter is reserved at the top, is convenient to molding, does not pour into gypsum.With two wide 20 millimeters, shape is same as the baffle plate of body of heater, has kept off the both sides of first, pours into the gypsum of 20 millimeters thick, opens baffle plate, and both sides are trimmed, and digs out the mortise that engages with next piece, spreads big oil of releasing agent or suds, sequence number on the volume.When doing second portion, only put a baffle plate at two, three part die joint places, gypsum perfused after, at the mortise place of first, second portion is tenon, two parts play the tenon effect when engaging, Yi Bian the baffle plate of second portion also digs out mortise.Like this, make eight parts successively, wait and take apart after half-dried, shaping reaches requirement size, profile, and 440 millimeters of largest circumference φ are high 370 millimeters.Varnish coating after drying in the shade is promptly done internal mold (2) and is used.During use, number combination is fixed with rubber belt in order.Material on φ c top with 120 millimeters covers, and uses little plank piece thick 20 millimeters on 4115 stickers then outside 120 millimeters circumference of φ from the top down, the size of wooden unit and shape, and with the gap minimum, the surface is as far as possible slick and sly for well.Glue is taken plaster mold apart after doing, and makes body (3).Paste the Cortex walnut (4) of 10 millimeters thick with 4115 glue by designing requirement at body (3) outer surface, bottoming then, last purplish red is brushed the Polyurethane lacquer 4 times, and so far, body of heater makes.Use at last with method or engraving, kneading is made two dragons and furnace bottom (5), and to design attitude, the interwined dragon incense burner is all carried out with 4115 stickers.This incense burner is only used the plate of 20 millimeters thick, can save high-quality timber, and material-saving is more than 80%, and cost reduces by 85%, and goods are firm, do not produce deflection deformation.

The purpose of manufacturing mould is to produce in batches, and less large-size wood structure goods of production quantity sometimes as various spheroids, cone, CLB more than 1000 millimeters, adopt unpainted clay idol get final product, just can finish small plate along the surperficial well-regulated stickup of unpainted clay idol.

Claims (5)
