The invention discloses a weaving needle for layered weaving. The weaving needle is characterized by comprising a yarn feeding head, a needle body, a yarn discharging head and an extending rod. The yarn feeding head, the needle body, the extending rod and the yarn discharging head are respectively manufactured and are then assembled into the weaving needle, so that the processing difficulty can be effectively reduced; the quality stability is improved; the abrasion of the weaving needle on the fiber can be reduced, so that the performance and the quality stability of large-scale complicated and thick prefabricated bodies can be improved.
Description
Technical field
The present invention relates to one and weave pin for layering is woven, belong to composite three dimensional and weave field.
Background technology
Invention number is that the patent of CN201010125066.5 proposes a kind of composite preform layering weaving method based on digitlization layout template, the method can molding large, complexity, abundant composite preform, meets defence and military, Aero-Space to the active demand of large complicated, abundant composite product.In the method, digital arrangement template is made up of the arrangement template arranging through hole according to certain rules and the guide rod that matches with through hole.Adopt the method to carry out precast body manufacture type, weave pin and pull yarn, run along guide rod gap, yarn is laid in fairlead gap.Invention number is that the patent of CN201010125069.9 proposes one for the woven pin of weaving of layering, and this is weaved, and pin employing is outside the hollow tubular structures or sewing needle structure that capture structure.For reducing fiber attrition, require to process tubular structure inside, therefore this structure to weave pin difficulty of processing large; crudy can not ensure; often can wear and tear fiber, thus cause composite product performance to reduce, and layering weaving process reliability also can be caused to reduce.
Summary of the invention
For the technical barrier such as solve in prior art the knitting needle wearing and tearing fiber that exists and difficulty of processing is large, quality is unstable, the present invention proposes a kind of knockdown needle construction of weaving, this is weaved pin and comprises into loose thread, needle body, goes out loose thread; Described enter loose thread adopt the one in snap joint, screw thread or jackscrew to be connected with needle body, junction adopt tapering or end face location; Described needle body with go out loose thread and adopt the one in snap joint, screw thread or jackscrew to be connected, junction adopts tapering or end face location;
Further, describedly also comprise extension rod for the woven pin of weaving of layering, described extension rod is with described needle body and go out between loose thread all to adopt the one in snap joint, screw thread or jackscrew to be connected, and junction adopts tapering or end face location;
Further, enter loose thread, needle body described in, go out loose thread and extension rod can adopt identical or different material manufacture;
Further, entering loose thread, needle body, extension rod described in and going out loose thread to adopt same material also can adopt unlike material.
Further, described extension rod can be an entirety with needle body, can be also an entirety with going out loose thread.
Further, described in enter loose thread and adopt the one in snap joint, screw thread or jackscrew to be connected with needle body, junction adopts tapering or end face location; Described needle body is connected with the one adopted in extension rod snap joint, screw thread or jackscrew, and junction adopts tapering or end face location; Described extension rod with go out loose thread and adopt the one in snap joint, screw thread or jackscrew to be connected, junction adopts tapering or end face location.
Further, enter loose thread described in comprise yarn guiding port, initiatively send yarn and broken yarn clamping device.The conical surface that described yarn guiding port can become for shaped form, the conical surface that also can become for linear; Described yarn and the broken yarn clamping device of initiatively sending comprises initiatively yarn feeding wheel, contact roller, drive motors, support composition.When weaving pin pulling yarn along guide rod gap lay yarn, drive motors drives initiatively yarn feeding wheel to rotate, and realizes initiatively sending yarn under the compression of contact roller.When yarn breakage, drive motors stops operating, and initiatively yarn feeding wheel and contact roller acting in conjunction realize broken yarn clamping.
Further, enter described in loose thread by smooth surface and the high material of hardness process, as pottery, ruby, wolfram steel.
Further, described needle body outer wall is processed with the structure of convenient clamping, and described clamp structure can be boss also can be groove.
Further, described needle body can be obtained by the one in wolfram steel, stainless steel, carbide alloy.
Further, described extension rod can select different length according to precast body demand, also can splice; All there is joint at described extension rod two ends; Described joint can be snap joint, also can be helicitic texture.
Further, described extension rod can be obtained by the one in wolfram steel, stainless steel, carbide alloy.
Further, described in go out loose thread can be the inner straight tube being processed with curve guide structure, can be rigidity bend pipe, also can be flexible elbow.
Further, the material going out loose thread described in can be pottery, ruby, wolfram steel, stainless steel, polytetrafluoro, metal bellow, pvc wired hose, plastic bellows hose wherein one or more.
Because the present invention adopts into loose thread, needle body, extension rod, goes out after loose thread manufactures respectively to be assembled into the preparation method of weaving pin again, effectively can reduce difficulty of processing, put forward high-quality stability, reduce the wearing and tearing of weaving pin, thus improve the Performance and quality stability of large-scale, complicated, abundant precast body.
