The making method comprises the following steps: tailoring the materials; making mandrel; shaping; winding wood layer on the surface; moulding; toasting; solidifying; cooling; stripping; extracting the mandrel; canning the core. The invention simplifies the manufacturing technique with high efficiency, which keeps wood sense of traditional stick with stable stick property and reliable quality.
Description
Technical field:
The present invention relates to a kind of stringed musical instrument bow stick, especially relate to by timber and compound stringed musical instrument bow stick and the system method thereof of carbon fiber.
Background technology:
The articulation type of stringed musical instrument is to rely on mechanical forces to make the string of a musical instrument vibration pronunciation of tensioning, stringed musical instrument is from its articulation type, mainly be divided into bow and draw chord crying musical instrument and play chord crying musical instrument, bow draws chord crying musical instrument to comprise violin, viola, violoncello, times contrabass, electric bass and urheen etc.Wherein bow draws the bow stick in the chord crying musical instrument to have decisive influence to playing the performance quality, except the dexterity used whether, each bow stick all has the tone color of itself.The length of bow stick, weight, equilibrium point, flexibility, bending strength and elasticity all have strict requirement because the harsh requirement on the performance, the timber crystal seed that can be used for doing bow stick seldom, the assortment of especially senior violin is just rare especially.
Bow stick material in the present employed stringed musical instrument is mainly with the Bai Ernanbuke wood of Brazil, and it is main being commonly called as the import bush.This wood plants that material is lightly tough and tensile, high resilience, texture is tight and fiber is long, and is not yielding once making.During making according in the line of timber itself and the blanking of the specification of stringed musical instrument bow stick size, under physical environment, place airing more than 1 year, advance the drying room oven dry then, the humidity of timber is controlled in 8%, craft by saw, plane, shovel, file processes again, be baked into the bow stick material of camber basically identical, this processing mode is a kind of typical workshop-based production model.The employed import bush of bow stick is not only the ideal material of doing bow stick, also is used to make famous and precious furniture and medical aspect, be in great demand, and the production of this kind timber is slow, and it is high that it is worth, and causes stringed musical instrument bow stick cost very high; Again because of the volume of timber itself has difference on size, the specification, so density all has difference in the line, and the effect that causes the quality of product also to be difficult to unanimity, use also is not quite similar.
Summary of the invention:
One of purpose of the present invention be for overcome traditionally with timber make that the quality of stringed musical instrument bow stick is inconsistent, consumptive material consumption worker when manufacturing, technology is complicated and product is easily broken shortcoming, provide that a kind of cost is low, steady quality and have timber and the compound stringed musical instrument bow stick of carbon fiber of timber bow stick superficial makings.
Two of purpose of the present invention is for a kind of above-mentioned timber and compound stringed musical instrument bow stick method for making of carbon fiber of producing is provided.
One of purpose of the present invention is achieved in that a kind of timber and the compound stringed musical instrument bow stick of carbon fiber, described bow stick comprises hollow carbon fiber bow stick, irritating in the described hollow carbon fiber bow stick has mixture of epoxy resins, and it is characterized in that: the ratio of described mixture of epoxy resins percentage by weight is: epoxy resin 50-60%, carbon fiber powder 20-35%, hardening agent 15-30%; Described bow stick coated outside has layer of wood.
Two of purpose of the present invention is achieved in that the method for making of the stringed musical instrument bow stick that a kind of timber and carbon fiber are compound, and it is characterized in that: it comprises the following steps:
(1) cuts out material, according to the required carbon fiber cloth that cuts of making the stringed musical instrument bow stick;
(2) make plug, the shape of processing plastic plug and specification as required;
(3) the curling shaping rolls the carbon fiber cloth that cuts on the plastics plug that shapes by hand; At the layer of wood that is coated with of carbon fiber bow stick, layer of wood the layer of wood of sheet is wound on the bow stick with 360 degree, and adhesion is fixed for to make the schistose texture that thickness is 1.5-3.5mm by timber;
(4) mold pressing is put into required mould to rolled carbon fiber rod together with plug, and the pressure that imposes more than 1500 kilograms compresses;
(5) bake, the above-mentioned mould that has compressed is put into baking oven, heat, be incubated then more than 50 minutes, solidified to more than 100 ℃;
(6) take out mould in the baking oven and put into cooling pond water and force to cool off more than 2 minutes, mold temperature is reduced to below 40 ℃;
(7) demoulding is loosed core, and disengageding mould takes out workpiece, extracts plug, and the stock of the carbon fiber stringed musical instrument bow stick of a hollow is finished;
(8) irritate core, pour in the hollow bow stick after stirring with mixture of epoxy resins, cold curing can be decided according to weather condition more than 20 hours.
The ratio of described mixture of epoxy resins percentage by weight is:
Epoxy resin 50-60%, carbon fiber powder 20-35%, hardening agent 15-30%.
Described wooden be import bush or letterwood.
The thickness of described layer of wood is the schistose texture of 2-3mm,
The invention has the beneficial effects as follows that cost is low, the carbon fiber that extracts from oil can use by import substitution timber in a large number; Processing technology and equipment are simple, and easy operating can adopt pipelining, the efficient height; Because of the outside surface of stringed musical instrument bow stick adopts layer of wood, kept the conventional effects of wooden bow stick, have the texture of log, adopted stay-in-grade carbon fiber because of its inside again, make stable performance, the reliable in quality of bow stick; Because whole bow stick only uses one deck timber on the surface, therefore can save high-class timber in a large number, has protected natural resources.
