Yarn-feeding device is mainly places macromolecular fibre rove yarn group creel necessary to production.Structure is typically very compact, so Floor space can be reduced.Size depends on the number of yarn group, and the number of yarn group depends on the size of product.General requirement Consolidate, change that yarn is convenient, guide freely, no any obstacle, and can be applied in combination.There are frame and two kinds of forms of comb, can be by dress foot Wheel, is easy to move, send the felt device various felt materials being mainly placed in the material shelf that can smoothly derive exactly；It is being sent into During it is not necessary to felt material increase tension force；Felt material general not impregnation under normal conditions, is sent directly into mould；
（2）Gumming device
Gumming device is made up of resin storage tank, guide roller, pressure roller, dividing sinker screen, Extruded roller etc..It is equipped with guide press roller, tree in groove Want shape to have a certain degree before and after fat groove, so that the angle of bend when passing in and out resin storage tank for the rove is unlikely to too big and increase and open Power.In order to be able to adjust the temperature of resin, if must also be added with heating using epoxy resin, vinylite, polyurethane resin etc. Device；
（3）Pre-shaping device
Pre-shaping device is progressively to remove unnecessary resin according to the reinforcing material that the requirement of product kind makes soaked with resin, Exclusion bubble, the yarn needed for product and felt is combined reasonably, exactly it is ensured that their relative position make its shape Shape is tapered and entry shape close to shaping mould.Then enter back into mould, carry out forming and hardening.Pre-shaping device is not fixed Pattern, to be designed according to the shape of product and requirement and operating habit；
（4）Mould
Mould is the important tool of hot setting drawing process, mould cross-sectional area and product cross-sectional area Ratio typically should be greater than or wait 10, to ensure that mould has enough strength and stiffness, uniform heat distribution and stable after heating.Become The length of pattern tool is to be determined according to hauling speed in forming process and resin gel curing rate, to ensure to reach during product pull-out To demoulding state of cure.Typically adopt steel chromium plating, cavity surface is bright and clean, wear-resisting, to reduce the frictional resistance in drawing and forming With the raising mold use life-span；
（5）Pulling equipment
Traction machine is the main frame in hot setting drawing process, and it must possess clamping and traction two big functions, chucking power, traction Power, hauling speed are both needed to adjustable.Traction machine has crawler type and fluid pressure type two big class.The feature of caterpillar tractor is that motion is flat Surely, velocity variable is little, structure is simple has the section bar of the plane of symmetry, rod, pipe etc. it is adaptable to produce.Another kind is drum hydraulic tractor, There is volume compact, inertia little, stepless speed regulation, stable movement can be realized within a large range, match with electric, compressed air Close, it is possible to achieve multiple automatic；
（6）Cutter sweep
Typically adopt the circular saw formula synthetic diamond saw blade of standard, have manual cutting and surface trimming.Automatic gas cutting machine is permissible Automatization for hot setting drawing process provides safeguard, in hgher efficiency.
4th, auxiliary equipment
（1）Dispensing instrument
Carry out continuous and stable for ensureing the production of hot setting drawing process, the preparation of sizing material should be accurate, accomplishes institute as far as possible Join the concordance of sizing material；
（2）Mixing plant
Blender is one of pultrusion production line main auxiliary equipment.Hydraulic elevation type blender can meet hot setting stretching Technique prepares the needs of sizing material；
（3）Cut felt machine
Hot setting drawing process produce in fiberglass batts will according to concrete product need be cut into Rack Size, generally to meet production needs using cutting felt machine with cutting out felt machine.Cutting felt machine is the special equipment cutting various fiber felt, is One of pultrusion production line auxiliary equipment.The wide cutting demand of different felt volume amounts, different felt can be completed, easy and simple to handle, cut outside felt Table is neat, accurately.
5th, technological process
Hot setting drawing process process is formed by sending the operations such as yarn, impregnation, preforming, solidifying and setting, traction, cut-out；No Twist with the fingers rove after creel extraction, enter resin storage tank through feed carrier and be impregnated with resin adhesive liquid, subsequently into preforming mould, will be many Cotree fat and bubble are discharged, and enter back into shaping mould gel, solidification.Product after solidification is continuously drawn from mould by traction machine Go out, finally by cutting machine customized cut-off；
（1）Technology controlling and process
The parameter that hot setting drawing process controls mainly includes forming temperature, hardening time, drawing tension and hauling speed etc.； In thermal parameter, pulling rate, three technological parameters of pull strength, thermal parameter is to be determined by the characteristic of resin system, is hot setting The primary factor that should solve in drawing process；When the principle that draw speed determines is the gelling at temperature in given mould Between it is ensured that product in a mold portion gelling, solidification；The restraining factors of pull strength are more, such as：It and mold temperature relation is very big, And it is stretched the control of speed.The increase of pulling rate directly influences second peak value of shear stress, i.e. cutting at dispersal point Shearing stress；For improve production efficiency, typically improve pulling rate as far as possible；So die shear stress can be reduced, and product table Face quality；For thicker product, relatively low pulling rate should be selected or using longer mould, increase mold temperature, its object is to Product is enable preferably to solidify, thus improving the performance of product；In order to reduce pull strength, make the smooth demoulding of product, using good Releasing agent be very necessary, this plays conclusive effect in moulding process sometimes；
