Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Shown in Figure 2, monofilament co-deflection device in the middle of a kind of steel cord for engineering tire core strand, including front anamorphoser 1, post-former 2, line concentration nozzle 3, heart yearn traction wheel 4, noseplate 5 and spacing guide wheel 6, described front anamorphoser 1 and the cylindrical anamorphoser that post-former 2 is different-diameter, described spacing guide wheel 6 is made up of two U-type groove guide wheels, after two U-type groove guide wheel Guan Bis, interstitial hole is rounded, and aperture is the 110% of twisting steel cord diameter；Described heart yearn traction wheel 4, front anamorphoser 1, post-former 2, spacing guide wheel 6 and line concentration nozzle 3 set gradually, heart yearn 8 direction of routing: being sequentially passed through heart yearn traction wheel 4, front anamorphoser 1, post-former 2, spacing guide wheel 6 and line concentration nozzle 3 by Loosen up wire wheel unwrapping wire, described heart yearn 8 sequentially passes through the direction of routing horizontal linear of heart yearn traction wheel 4, front anamorphoser 1, post-former 2, spacing guide wheel 6 and line concentration nozzle 3；Described noseplate 5 is arranged on the front of spacing guide wheel 6, production needs according to steel cord difference layer structure, outer layer upper thread 9 can comprise multifilament or steel wire strand stock, outer layer upper thread direction of routing: is sequentially passed through noseplate 5, spacing guide wheel 6 and line concentration nozzle 3 by Loosen up wire wheel unwrapping wire through upper thread traction wheel 7.
To produce steel cord 0.25+6 × 0.25 structure, before a 0.25mm monofilament in the middle of heart yearn 8 unwrapping wire is sequentially passed through on heart yearn traction wheel 4 after two circles after anamorphoser 1, post-former 2, spacing guide wheel 6, line concentration nozzle 3, tiing a knot after removal tieing together with upper thread 9 six roots of sensation monofilament and carry out twisting, a middle 0.25mm monofilament encloses with each coiling one on post-former 2 and with line concentration nozzle 3 and heart yearn traction wheel 4 on the same line at front anamorphoser 1.Steel cord is when twisting crosses tieing, in the middle of observing, a monofilament is behind the centre position of upper thread 9 six roots of sensation monofilament, two spacing guide wheels 6 are closed, spacing guide wheel 6 is in centre position with line concentration nozzle 3 of noseplate 5 and with post-former 2 on the same line, spacing guide wheel is made up of two U-type groove guide wheels, after spacing guide wheel Guan Bi, the interstitial hole of two U-type groove guide wheels is rounded, and aperture is the 110% of twisting steel cord diameter.Line concentration nozzle 3 with on spacing guide wheel 6, post-former 2, front anamorphoser 1, heart yearn traction wheel 4 straight line in the same plane.According to steel cord difference layer structure needs, during as produced the steel cord such as 1+6,1+6+12,7 × 7,7 × 9 series, front anamorphoser 1 and post-former 2 can be the cylindrical anamorphoser of different-diameter, are alternatively the Polyhedral hexagonal anamorphoser of different-diameter simultaneously.
This utility model simple in construction, aspect operates, and effect is notable.Before not using this device, 7 × 7 Series Steel cords of production have monofilament in the middle of steel cord core strand to sting out surface of tyre phenomenon for engineering tyre, affect tire used safety.A monofilament in the middle of 7 × 7 steel cord core strand is carried out extraction force detection average out to 4N, underload percentage elongation average out to 0.097%, standard deviation 0.019；After adopting this device, in the middle of 7 × 7 steel cords of production, a monofilament carries out extraction force detection average out to 12N, underload percentage elongation average out to 0.084%, standard deviation 0.010；Use 7 × 7 Series Steel cords that this device produces for engineering tyre simultaneously, verify through the use over 2 years, find no monofilament in the middle of steel cord core strand and sting out the phenomenon of surface of tyre, constant product quality, carried out mass production.
Embodiment is only to facilitate understand the technical solution of the utility model; it is not intended that the restriction to this utility model protection domain; every without departing from any simple modification, equivalent variations and the modification perhaps according to technical spirit of the present utility model, above scheme made in technical solutions of the utility model, all still fall within this utility model protection domain.
