Background technology
Carbon fiber is a kind of fiber material section that is made of elemental carbon, is to be formed through high temperature (700~1000 ℃) carbonization by organic fiber, and phosphorus content is higher than 90% macromolecular fibre, and wherein phosphorus content is higher than 99% the graphite fibre that is called.The axial strength of carbon fiber and modulus height, no creep, fatigue durability is good, and specific heat and electric conductivity are between nonmetal and metal, and thermal coefficient of expansion is little, and resistance to chemical reagents is good, and the density of fiber is low, and the X ray permeability is good.Carbon fiber can be divided into polyacrylonitrile-radical, asphaltic base, viscose glue base and phenolic aldehyde base etc. by the precursor kind, then can be divided into universal (GP) and high-performance type (HP) two classes by mechanical property.About common carbon fiber intensity 1000MPa, modulus 100GPa, high-performance carbon fibers can be divided into high strong type (intensity 2000MPa, modulus 250GPa) and high model (modulus is more than 300GPa) again.Intensity is called the superelevation strong type greater than 4000MPa person; Modulus is called the superelevation model greater than 450GPa person.Along with the development of space flight and aircraft industry, high-strength height also occurred and stretched type (intensity greater than 49000MPa, ductility greater than 2%) new varieties.
Existing a kind of Chinese utility model patent that is called " a kind of large-tow carbon fiber expanding unit " for the CN200920282868.X name discloses a kind of structure, its structure comprises the heating roller and the frame of rolling tube, at least one pair of tangent setting, described heating roller and frame are rotationally connected, and described rolling tube is driven by drive unit and rotates.Described heating roller is preferably 2~10 pairs, and the space certain distance is arranged on the described frame; Describedly respectively heat the axis of roller and the axis of described rolling tube is arranged in parallel; Described heating roller can be rotated by motor-driven; This utility model large-tow carbon fiber expanding unit is simple in structure, with low cost, and little, the fiber utilization rate height of products thickness made of carbon fiber after its expansion, makes properties of carbon obtain giving full play to.But its shortcoming is this device can only be applicable to large-tow carbon fiber, and inapplicable widening little tow carbon fiber, be 6mm or widen as width less than the carbon fiber wire of 6mm, the more important thing is, carbon fiber bulking intensity after this device is widened is not enough, be difficult to improve the wettability of carbon fiber, product shear strength and rigidity intensity after compound are lower, so its structure awaits to improve.
Summary of the invention
Technical problem to be solved by this invention is the expansion silk device that a kind of carbon fiber wire is provided at above-mentioned prior art present situation, and its carbon fiber wire that expands behind the silk has the wettability height, can effectively improve the shear strength and the rigidity intensity of joint product.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the expansion silk device of this carbon fiber wire, comprise that the carbon fiber wire that sets gradually unreels tube, the heater of heating carbon fiber wire, widen device and thereon the rolling tube of carbon fiber wire being reeled, the rolling tube is by the motor-driven setting, it is characterized in that: the described tube that unreels is provided with the strainer that makes carbon fiber wire generation tensile force when carbon fiber wire along with rolling tube coiling, described heater is two live metal roll shafts that are provided with at interval, when unreeling carbon fiber wire after tube go up to launch when walking around two live metal roll shafts, constitute the current loop that carbon fiber wire generates heat between carbon fiber wire and two metal roller shafts.
As improvement, the described device of widening is for widening plate, this is widened plate and is provided with the widen through hole of width greater than the carbon fiber wire width, when carbon fiber wire passes after heater heating when widening through hole, enter the carbon fiber wire upper surface of widening behind the through hole and contact, and the carbon fiber wire lower surface after passing from widen through hole contacts with the upper surface of widening plate with the bottom surface of widening plate.
As improvement, the described device of widening is two rotating shafts that be arranged in parallel, when carbon fiber wire passes between two rotating shafts after the heater heating, carbon fiber wire upper surface before entering contacts with the bottom surface of first rotating shaft, and the carbon fiber wire lower surface that passes after entering contacts with second rotating shaft upper surface.
Improve, described strainer is a pressure roller again, the roll surface of this pressure roller and tangent being set together that unreel that is wound with carbon fiber wire, and an end of this pressure roller and the rotatable setting of connecting rod one end, and the other end of connecting rod links together with the turning cylinder that is provided with torsion spring.
Compared with prior art, it is two live metal roll shafts that are provided with at interval that the present invention adopts heater, when unreeling carbon fiber wire after tube go up to launch when walking around two live metal roll shafts, constitute the current loop that carbon fiber wire generates heat between carbon fiber wire and two metal roller shafts.This carbon fiber wire after two metal roller shaft heating, its firing rate is fast and temperature stability good, carbon fiber wire after widening, its bulking intensity height, so-called bulking intensity is meant that thinner, the mutual space of strand in the carbon fiber wire after widening is bigger, thereby improved the wettability of carbon fiber wire effectively, the shear strength of joint product and rigidity intensity are increased considerably, reached the better purpose of application of carbon fibres silk performance.
