Description

 The invention relates to furniture production and can be used for the manufacture of high-quality furniture with imitation of solid wood.

 Prestigious expensive furniture made of solid solid wood is decorated by removing part of the wood surface, or by supplementing the surface with parts also made of solid wood (see, for example, the article “Production of furniture facades” from the “Wood Work ent”, USA "Technology and equipment of logging, woodworking and pulp and paper industry" N 5 for 1994) Such furniture is available to a narrow circle of consumers due to the high cost of materials and the complexity of manufacturing.

 More affordable furniture is made from variously prepared wood waste coated with veneers. Decorative facade details of such furniture are made in the form of laid on profile elements and layouts of a closed circuit (see, for example, furniture from the Yerevan furniture factory from the "World of Furniture" N 1 for 1994, p. 15).

 Known methods for the manufacture of furniture stylized as solid wood furniture. Such furniture is made of the simplest wood material such as chipboard, veneered, and decorated with profile selection. The selection is carried out by a curly cutter according to the template, glued to a sheet blank and carefully processed along the contour. Processing includes putty, grinding, varnishing, etc. Such technological operations complicate and increase the cost of the process, as well as identify low-grade wood material used in the product, which reduces the aesthetic parameters of the products (see, for example, furniture of the Arabkir furniture factory, J. "World of Furniture" N 5 for 1994, pp. 15-16 )

 The closest solution to the proposed can be considered a method of manufacturing shaped parts according to the application of Germany N 4206021, class. B 27 K, 5/02, publ. 2.09.93, including the profile development of sheet blanks, which consists of several layers of veneer glued together. The sample is then carefully processed at the office and glued to the carrier base. The use of veneers makes technology more expensive, and gluing and processing of several layers (carrier, several intermediate and integumentary) complicates the production.

 The purpose of the invention is the development of a technological process for the manufacture of facade surfaces of furniture cases, which allows to reduce the complexity of furniture manufacturing and improve its quality by simulating solid wood.

 To achieve the goal in the method of manufacturing facade surfaces of cabinet furniture, including the implementation of the shaped element from sheet billets by means of profiled sampling and fixing it on a supporting base, for the manufacture of the shaped element, a billet of wood fractions of small fractions on an adhesive basis (fiberboard, MDF) with glued on it on both sides with decorative veneer.

 The carrier base may be in the form of a contour frame.

 Profile sampling can be cut from a sheet blank with a laser beam.

 The use of material such as fiberboard and MDF in the proposed method provides a complete simulation of furniture made from solid massive wood species, and also significantly reduces the complexity of manufacturing and increases productivity by eliminating a number of finishing operations.

 A sheet blank made of fiberboard or MDF, on which decorative veneer from various types of wood is glued on both sides, can be selected as a carrier base. The veneer pattern is pre-selected to simulate a single piece of wood. It is possible to use a frame design with an infill in the inner contour as the supporting base. Instead of a panel, glass (a bookcase, sideboard) or a mirror (a wardrobe) can be used.

 For the manufacture of shaped elements, sheet blanks from wood fiber of small fractions on an adhesive basis such as fiberboard or MDF are used. A decorative veneer with a pre-selected pattern is glued onto the sheet headers on both sides. Veneer sticker on both sides eliminates deformation of the part. The workpiece is pressed, varnished and goes to the operation of profile sampling.

 The operation of profile sampling is performed on a milling machine with a curly cutter according to the template. It is also possible for large-scale production to use laser systems in which the internal sample is made by a laser beam according to a complex configuration incorporated into the installation.

 Billets for shaped elements can be made of separate pieces of wood material, rigidly interconnected and glued with veneer.

 The cut shaped elements are processed along the contour and then glued to the supporting base, pressed, sanded and varnished.

 Shaped parts made of fiberboard and MDF have a uniform edge structure, are easily processed and provide the impression of a profile sample of solid wood.

 Shaped elements of furniture imitated under high-grade wood furniture are in the form of rather wide overlays of various configurations along the external contour of the supporting base (photocopy of furniture samples are included).

 In FIG. 1 shows an explosion diagram of a carrier base and profile sample; in FIG. 2 bearing base of the frame structure; in FIG. 3 is a sectional side view of the structure of FIG. one; in FIG. 4 is a sectional side view of a body part with a frame base.

 The carrier base 1 (Fig. 1) is a sheet blank made of fiberboard or MDF 2 sheet, on which veneer 3 and 4 are pasted on both sides. Of the same sheet heading, consisting of fiberboard or MDF 2 with veneer 3 and 4, a shaped element 5 is made by profile sampling, which is then glued to the base 1. The resulting product is processed according to the internal and external contours.

 The material selected for furniture manufacturing has a homogeneous fiber structure over the cross section and the ability to preserve it during machining in the process of obtaining embossed surfaces. MDF and MDF are made of wood fiber of fine fractions on a glue basis, combine well with veneers glued to them and, after contouring, give the impression of imitation of solid wood.

 In FIG. 2 shows a blank of the carrier base in the form of a contour frame 6. A panel, glass or mirror can be inserted along the inner contour of the frame 6.

 In FIG. 3 shows a side view of a facade surface consisting of a shaped element 5 glued to the supporting base 1 in the form of a sheet (Fig. 1).

 In FIG. 4 shows a side view of a facade surface consisting of a shaped sample 5 glued to a contour frame 6.

 The shaped element 5 can be cut from a solid sheet material, as well as from a workpiece consisting of individual fragments.

 Contour sampling can be performed by a curly cutter according to a template or by a laser beam according to a given program.

 After the contouring operation, special edge processing is not required. The edges are cleaned and ground together with the rest of the façade surface.

 Facade surfaces made by the proposed method create a three-dimensional impression of a part made from a single piece of solid wood. The effect is achieved due to the rational selection of the material of the blanks of the bearing base and the shaped element, which is characterized by the homogeneity of the fibrous structure over the cross section and its safety during the machining of relief surfaces.

 Rational selection of material allowed to significantly simplify the process compared to furniture production using chipboard or multi-layer veneer, as well as improve the reliability and quality of products. Reducing the complexity of the production process has reduced costs and expanded the circle of consumers of high quality furniture.
