Description

A kind of fancy veneer clad can casing of piano

Technical field

The invention belongs to piano manufacturing technology field, particularly a kind of casing of piano.

Background technology

Piano discrete piano and horizontal piano, piano with its dulect tone color, body is big, parts are numerous, and is called as the king of musical instrument always.Piano had only a few peoples to enjoy in the past, cost an arm and a leg.Along with the raising of people's living standard, also in continuous increase, particularly numerous children and teenagers' education more need a large amount of pianos to the piano demand.Invar qin manufacturing cost height for the pianophile of vast non-piano specialty, is necessary to reduce the cost and price of piano, satisfies people's demand.In the piano component structural, except minorities such as rust iron, gagger, string, axle nail, screw adopt the metal material, most parts are but made by wood materials.Wherein shell is with the maximum part of amount of wood.With common wood or middle fiber or glued board, the casing of piano of making, it is not high also to exist class, not enough shortcoming very attractive in appearance.

Summary of the invention

The objective of the invention is, a kind of exquisite appearance, top grade, cost is lower, shape stability is good casing of piano are provided.

Technical scheme of the present invention is:

A kind of casing of piano, comprise cylindrical or square column type parts and plate shape parts, the surface scribbles transparent piano lacquer, Shell Plate shape parts post natural rare tree wooden decorative veneer by plate core and at least 1 face, natural rare tree wooden decorative veneer also can be pasted or do not pasted to cylindrical or square column type member outer surface, and the wooden decorative veneer is connected with adhesive with plate core and/or post core.

Above-mentioned board core material material is the timber jigsaw, or multi-plywood or medium density fibre board (MDF).

Above-mentioned natural rare tree wooden decorative veneer is sliced veneer or rotary cut venner, thickness 0.2-1mm.

Above-mentioned its shell is made because of cylindricality or square column type parts adopt the precious timber solid wood, can carve by designing requirement.

Before the above-mentioned piano lacquer coating, parts and the log parts of elder generation to posting the rare tree fancy veneer, the processing of mixing colours, piano lacquer is the colored varnish.

The above-mentioned colored varnish is a piano lacquer type organic coating, divides three brushings, and each mopping 10-15 minute at interval is advisable to this hard state with curing agent; The brushing lacquer painting is smooth, no rubbish, pore-free, no duck eye, and appearance should be repaired immediately; After the mopping 48 hours, after the paint film sclerosis, sand milling, polishing make casing of piano parts lacquer painting produce brightness.

The above-mentioned colored varnish is a piano resin sub-gloss varnish, to the sanding of case member openpore, painted after, the spray gun spray paint adds a small amount of look accurate adjustment look in the paint, spraying 3-5 road, last is finish paint together.

Advantage of the present invention and technique effect are: the board-like parts of casing of piano adopt natural rare tree timber fancy veneer veneer, with the solid wood jigsaw, or multi-plywood, or medium density fibre board (MDF) is a central layer, the casing of piano of Huo Deing like this, it is attractive in appearance that the surface scribbles piano paint outward appearance wood grain again, high-grade, and the cost price is lower, the purchasing power that is fit to vast ordinary consumer, this compound bending resistance non-deformability that can also improve the casing of piano parts, reduce and eliminated the different and seasonal variations of piano territory of use, humidity changes the influence that casing of piano harmomegathus is changed, particularly medium density fibre board (MDF) is a central layer, piano after date when using a section after medium density fibre board (MDF) is directly painted, the tangerine peel phenomenon appears in paint film, and technical solution of the present invention has solved this problem effectively.

Casing of piano cylindrical or square column type parts employing rare tree timber or common wood subsides rare tree timber fancy veneer, top grade both attractive in appearance, cost price is lower again, and whole casing of piano sense organ effect is very exquisite, and high brightness paint and sub-gloss varnish are to adapt to different consumers' aesthetic requirement.
