Description
Technical field
The present invention is the preparation method who is subordinate to a kind of musical instrument, musical instrument assembly, refers to the method for a kind of integrated metal or alloy musical instrument of preparation, musical instrument assembly especially.
Background technology
The spare part of conventional tube musical instrument, shown in Figure 2 for the stereogram of the wherein a kind of key lid in the wind instrument as shown in Figure 1, for this key covers by two exploded views that spare part constituted (annotate: some key cap assemblies number is more).This key lid is by the be welded key lid finished product of Fig. 1 of each other spare part more than two or two among Fig. 2, each other spare part then be utilize forge or lost wax casting made.
The processing procedure of aforesaid existing pipes musical instrument spare part has following disappearance:
1,, and must utilize manpower to do the modification of secondary operations in weld aesthetic property deficiency.
2, because the annealing problem behind the welding high temperature causes the intensity of weld relatively poor.
Must use the wlding of silver, cadmium, kirsite when 3, welding, heavy metal wherein can cause the severe contamination of environment.
Employed wlding is different with the density of the material of musical instrument own during 4, owing to welding, cause behind the finished product uniformity of whole instrument material itself poor, cause the resonance and the transmission that influence sound wave,, can't get a desired effect so what manifest is that the musical instrument tonequality and the sympathetic response that show are relatively poor.
5, the shown tonequality of coming out of each material and inequality, and aforementioned existing instrument material source is mainly section bar, so selectivity is low, can't meet the needs of, characteristics such as sympathetic response that for example can't respective material, transitivity find optimal material.
6, the processing procedure of aforementioned existing musical instrument, because man-hour is many, speed of production is slow, cost is relatively also high.
Summary of the invention
The present invention mainly provides the preparation method of a kind of musical instrument, musical instrument assembly.
The present invention is providing a kind of by prepared musical instrument of aforementioned processing procedure and assembly thereof in addition.
Processing procedure of the present invention consists predominantly of:
With at least a metal dust and the mixing thing that granulates of binding agent, the shared percent by volume of this binding agent is at 7%～61%;
Aforementioned shot-like particle is shaped to preformed thing blank;
Remove the binding agent in the aforementioned preformed thing blank;
Carry out sintering, blank is punctured into preformed thing size.
By the prepared musical instrument of above-mentioned processing procedure, musical instrument assembly, have following advantage:
One, can select the metal or alloy material according to tonequality, the sympathetic response of required musical instrument, and can accomplish the end in view, its convenience that can select instrument material is not that the traditional instrument processing procedure can be compared.
Two, according to the prepared musical instrument of processing procedure of the present invention, musical instrument assembly do not need the welding, specious, structure is strong.And one-body molded, consistent in density, material is even, and good sound wave resonance and transitivity are provided, and the tonequality and the sympathetic response that show are preferable.
Three, processing procedure of the present invention need not use welding, except reducing workflow, has avoided the pollution problem of using in the welding job that wlding caused yet.
Four, lacking of the fast and artificial usefulness of this processing procedure, comparatively economical comparatively speaking, production unit cost is low.
Description of drawings
Fig. 1: be the stereogram of existing pipes musical instrument key lid;
Fig. 2: be the exploded view of Fig. 1.
The specific embodiment
It below is the explanation of embodiments of the invention.
The preparation of musical instrument of the present invention and assembly thereof consists predominantly of follow procedure:
Select at least a metal dust is mixed with binding agent and the mixing thing that granulates, the shared percent by volume of this binding agent is at 7%～61%;
Aforementioned shot-like particle is shaped to preformed thing failed part;
Remove the binding agent in the aforementioned preformed thing blank;
Carry out sintering, and make blank be punctured into preformed thing size.
Employed metal powder granulates in this method, generally being selected at granularity is that 50 μ are following for preferable.And be the grain graininess size of selecting metal dust according to high, medium and low sound in this method, wherein, bass is grain graininess the greater, the grain graininess intermediate of middle pitch, and high pitch is then selected the smaller particles granularity.
In processing procedure of the present invention, its method mainly is that a kind of or several metal powder metal or metal alloy material as musical instrument and assembly thereof is selected in the tonequality of the musical instrument that obtains according to the institute desire or sympathetic response.
And aforesaid metal dust has comprised and has been selected from gold, silver, copper, iron, aluminium, nickel, chromium, molybdenum, platinum, palladium, rhodium, tin, lead, antimony, tungsten or its alloy person.
In processing procedure of the present invention, the main function of employed binding agent is the clad metal powder, and in shaping as solid shape purposes.
Employed binding agent mainly is to be selected from thermoplastic, paraffin or its mixture among the present invention.Wherein this thermoplastic such as polypropylene, polystyrene, resin etc.
In addition, the present invention then can use the injection molding method or extrude forming process and be preferred methods for two kinds in the processing procedure of moulding.
In the embodiment of injection molding method, this method is mainly shot-like particle is heated to below 220 ℃ in a Jet forming machine, and is injected into the mould internal shaping under the pressure of about 45～360MPa.
After the blank of pre-formed articles of the present invention is shaped, then must slough the binding agent in the blank, its method preferably has comprised following two kinds:
One, first method is dissolved binding agent for utilizing solvent, to remove the binding agent in the blank.
Most typical solvent such as trichloroethanes in aforementioned have good effect for thermoplastic.
Two, second method makes binder decomposed in a firing equipment blank being heated, to remove binding agent.In this heating process, also can merge the program of carrying out sintering simultaneously.
In processing procedure of the present invention, the temperature of sintering is looked different metal or alloy and different temperature is arranged.And generally be between 650 ℃～2100 ℃.
In addition, in the method for the invention, optionally the preformed thing can be imposed all or partly forge becomes final size and density.Then must reserve the contraction thickness of 1～30% forging usefulness in the aforementioned forging processing procedure in desire forging place.
Aforementioned forging processing procedure then can be selected all to forge or partly forge.Wherein whole forgings then can obtain the instrument material of consistent in density, partly forge the instrument material that then can obtain different densities, utilize the different densities selectivity to obtain the instrument material of different conductibility and sympathetic response.
At last, the present invention can optionally impose sintering, K cryogenic treatment or sintering repeatedly and K cryogenic treatment to the preformed thing after forging processing procedure, make material more solid.
The above is the preparation method of musical instrument of the present invention and assembly thereof, is that the key lid with wind instrument is embodiment among this specification, but does not therefore limit the use of other musical instrument.
In sum, processing procedure provided by the present invention and the musical instrument that makes, musical instrument assembly, can improve the disappearance and inconvenience of giving birth to due to existing musical instrument and the assembly, have above-mentioned numerous usefulness and practical value simultaneously, therefore the present invention one highly utilizes the creation of law of nature, and does not see identical or approximate product public use in identical technical field.
