Description
Technical field
The utility model relates to a kind of composite processing device, is specifically related to a kind of easy to operate, the punching device of carbon fiber composite material article.
Background technology
The composite products such as carbon fiber have been widely used in the various electronic product of preparation, the plurality of advantages such as the shell such as automobile, aircraft, has hardness high, and quality is light, and decay resistance is strong, and stretch-proof performance is strong, not yielding.Carbon fiber product sometimes needs punching in preparation process, and prior art is when carrying out drilling to carbon fiber composite material article, no matter is cutting tool choice or drilling parameter, all along the drilling pattern practising metallic article.Therefore, very easily occur layering during drilling, the phenomenons such as fiber tearing, the product quality prepared is low, and the production cycle is long, inefficiency.And the major diameter drill bit of existing drilling or reamer are all be material with high-speed steel, because hardness ratio composite is slightly poor, therefore after completing a small amount of drilling, the cutting edge of cutter is worn, when again carrying out drilling, cannot cut staple silk, but with the rotation external force run up to pull apart filament, cause being formed and be separated layering, produce the overproof overproof rate having < 12%.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, easy to operate, there will not be carbon fiber product layering in boring procedure, the phenomenons such as fiber tearing, the firm nonabradable punching device of drill bit.
Summary of the invention
Goal of the invention: technical problem to be solved in the utility model overcomes the deficiencies in the prior art, there is provided a kind of result reasonable in design, workable, production efficiency is high, can efficiently hole to carbon fiber product, there will not be carbon fiber product layering, the phenomenons such as fiber tearing, the firm nonabradable punching device of drill bit.
Technical scheme: in order to realize above object, the technical scheme that the utility model is taked is:
A punching device for carbon fiber composite material article, it comprises electro spindle, the drill bit be connected with electro spindle, is arranged on the drilling dynamometer immediately below drill bit, and described drilling dynamometer is placed on milling machine table, and described electro spindle is connected with motor;
The length of described drill bit is 5 ~ 15 centimetres, and drill bit is 36 degree of helical angles, and the drift angle of drill bit is more than or equal to 127 degree, and bit diameter is 0.02D ~ 0.5D.
Described drilling dynamometer is provided with the fixed clamp bar of fixing carbon fiber composite material article.
Preferably, the punching device of above-described carbon fiber composite material article, described drilling dynamometer is connected with electric charges amplify instrument.
Preferably, the punching device of above-described carbon fiber composite material article, described electric charges amplify instrument is connected with computer.
The punching device of carbon fiber composite material article described in the utility model, drill bit is connected with electro spindle, electro spindle is High Rotation Speed under the drive of motor, hole, the utility model, according to the feature of carbon fiber product, has carried out a large amount of experiment screenings to the structure of drill bit and shape, the length optimizing drill bit is 5 ~ 15 centimetres, drill bit is 36 degree of helical angles, and the drift angle of drill bit is more than or equal to 127 degree, and bit diameter is 0.02D ~ 0.5D.And carbon fiber product is placed on drilling dynamometer, can control in the course of work in real time, the active force of drill bit, prevent drill bit firmly excessive, and on drilling dynamometer, be designed with the clamping device of fixed carbon fibre, can ensure to there will not be movement in boring procedure, thus the phenomenon such as layering, fiber tearing can effectively avoiding carbon fiber product to occur when drilling, can significantly improve production efficiency and product quality, and the hole circle prepared is sliding, overproof rate is less than 1%.
Beneficial effect: the punching device of the carbon fiber composite material article that the utility model provides is compared with prior art products and had the following advantages:
The punching device of the carbon fiber composite material article that the utility model provides, with reasonable in design, workable, efficiently can hole to carbon fiber product, there will not be carbon fiber product layering, the phenomenons such as fiber tearing, and drill bit is firm not easy to wear, production cost is low, and the hole circle slippery prepared is high, quality is high, and overproof rate is less than 1%.
