Abstract
A tophan pot is composed of the pot body which is made of carbon fibres as reinforcing material and epoxy resin liquid as basic raw material through winding, and the pot bottom which is made up of carbon fibres reinforced nylon particles through injection moulding. The pot body and pot bottom are tightly assembled together. Its advantages are high strength, modulus, rotating speed and resistance to corrosion and fatigue, and light weight.
Description
(1) technical field
The invention belongs to field of textile machinery, be specially adapted to the spinning tophan box of viscose.
(2) background technology
In the spinning industry both at home and abroad, viscose accounts for the large percentage of total spinning amount, and one of them critical component is a tophan box in the spinning machinery.Tophan box is in the high speed rotation status in the course of the work, and the per minute rotating speed surpasses 8000 to be changeed, and also is subjected to the influence of corrosive medium simultaneously, the stress complexity, thereby require to have high intensity and corrosion-resistant fatigue performance, while dynamic balance performance excellence.Tophan box mainly is by the aluminium alloy moulding by casting both at home and abroad at present, obtains finished product through after the machining then.Though the tank body of this type can satisfy the requirement of serviceability, but weight is big, rigidity is little, and anti-fatigue performance is poor, corrosion-vulnerable, after using a period of time, tank body easily deforms and causes tank body off-centre, can cause tank body to break away from electric ingot when serious and cause the accident, simultaneously because weight is big, cause power consumption big, braking ability worsens.Because the electric ingot of current use is energy-saving electric ingot, driving force is limited, increases the tank body capacity and can make the application of electric ingot limited, causes technological improvement to become very difficult.
(3) summary of the invention
The invention reside in and solve the difficult problem that traditional tank body combination property is difficult to improve, development is applicable to the high-performance tophan box that the spinning raylande is used.
Carbon fiber is the high-performance inorganic fiber of a kind of phosphorus content more than 90%, and microstructure is a random graphits structure, and it is big to have intensity, the modulus height, and density is little, and is corrosion-resistant, and excellent properties such as antifatigue can form various high-performance composite materials with resin-bonded.
High-strength light carbon fibre composite tophan box of the present invention, by forming at the bottom of carbon fiber wound composite tank body and the carbon fiber reinforced nylon composite tanks, tank body and jar adopt bonding mode to couple together at the end.
The tank body of high-strength light carbon fibre composite tophan box is made by the carbon fiber wound composite, tank body has a tapering up and down, used resin matrix is an epoxy resin adhesive liquid, wherein containing weight epoxy percentage is 45-65%, methyl four benzonitrile anhydride curing agents percentage by weight 35-55%, and the percentage by weight of tank body proportioning raw materials is:
Carbon fiber: 60-85%
Glass fabric: 1-10%
Epoxy resin adhesive liquid: 30-50%
The jar end of high-strength light carbon fibre composite tophan box, made by carbon fiber reinforced nylon, and dish has a tapering at jar the end, and this tapering is consistent with the tank body tapering, and injection mo(u)lding is adopted at jar end.The percentage by weight of its raw material ratio is:
Nylon: 60-80%
Carbon fiber: 5-30%
Glass fibre: 10-35%
High-strength light carbon fibre composite tophan box is by tank body and jar end assembling moulding, tank body and two taperings at jar end partly closely cooperate during assembling, and to apply high-strength adhesive be one with its tight bond, and when guaranteeing to rotate at a high speed, tank body closes tightr with a jar bear building-up.
Carbon fiber tophan box main performance index: no-load power consumption is less than 110 watts, and rated speed is greater than 10000rpm, and the tank body elastic modelling quantity is greater than 140GPa, and the work running is steady, not explosion.
(4) description of drawings
Structure of the present invention as shown in Figure 1, by jar bottom 1, locating hole 2, the outer dish 3 in jar end, tophan box tank body 4 formations.Tophan box tank body 4 tapered structures, at the bottom of the first bottom of its conelet portion is equipped with jar, the jar end, is mainly by jar bottom 1, locating hole 2, jar dish 3 compositions at the end, and wherein dish 3 outsides also are tapered configuration at jar the end, and its tapering is big or small consistent with tophan box tank body 4 taperings size, jar bottom 1 is used to support whole tophan box, and locating hole 2 is used for tophan box and cooperates with tophan box drive unit electricity ingot axle location.During assembling, adhesive coating on the conical surface of dish outside at the bottom of the jar, then by the first side of the auger of centrifugal tank body 4, jar bottom 1 tophan box tank body 4 of packing into downwards, coil 3 male cone (strobilus masculinus) tight bond at conelet head end tank body 4 inner conical surfaces and jar end outward and cooperate and become one, under the normal operation centrifugal action, two conical surfaces increase with rotating speed, adhesion strengthens, and guarantees that security of system does not fly off.
(5) specific embodiment
With the 12K carbon fiber is fortifying fibre, is matrix with epoxy resin, and the carbon fiber reinforced nylon pellet is a jar end raw materials for production, and the specific embodiment of production tophan box of the present invention is as follows:
1 bundle 12K carbon fiber is walked around creel, enter the glue storage tank impregnation that contains epoxy resin, wherein weight epoxy percentage is 50%, methyl four benzonitrile anhydride curing agents percentage by weights 50%, through being wrapped on the steel mould consistent behind the resin controller with the tank body internal taper, utilize the main axis rotation mould of wrapping machine, utilize wrapping machine feeding trolley control winding angle, obtain the winding body of certain wall thickness, this is twined body put into curing oven together with mould, 120 ℃ of design temperatures solidify while rotating, behind the completion of cure, be put into together with mould and be worked into given size on the lathe, tank body is deviate from from mould, make the tophan box tank body.
According to profile at the bottom of the jar and dimensional requirement, processing tophan box jar rising pouring mold tool, with proportioning is 15% carbon fiber, 20% glass fibre, the carbon fiber glass fibre composite enhancement nylon pellet of 65% nylon 6 is put into the injection machine hopper, set 250 ℃ of injection temperatures, 70 atmospheric pressure of injection pressure are at the bottom of the injection mo(u)lding jar.
