Abstract
A technology for producing steel-wire cord includes such steps as choosing 11-12 I-shaped payoff wheels, winding steel wires on them, arranging them on the rocking basket of twisting machine, paying of steel wires in such manner that 3 steel wires are used for internal layer and others for external layer, making said payoff wheels to synchronously rotate in same direction while twisting them to form a cord, and winding it on a I-shaped receiving wheel.
Description
Technical field
The present invention relates to a kind of production method of all-steel cord, especially a kind of 3/8 or 3/9 or the production method of similar all-steel cord.
Background technology
Because all-steel cord can improve the rigidity of tire tyre protecting belt, is widely used in the tire manufacturing industry.Common all-steel cord specification comprises 3+6,3+9,3+9+15 ...
The all-steel cord mode of production of 3+6 or 3+9 specification comprises: first procedure be earlier through twisting machine three steel wires are twisted with the fingers " S " to or " Z " to the semi-finished product of 3*D, second operation work will go up semi-finished product that one procedure produces as heart yearn through compound twisting machine again, outsidely twist with the fingers the all-steel cord that 6 or 9 Production for Steel Wire go out 3+6 or 3+9 again.
The all-steel cord mode of production of 3+9+15 specification is: the product of the 3+9 that will produce with compound twisting machine is as heart yearn, is that the heart yearn outside of 3+9 is twisted with the fingers the all-steel cord that 15 Production for Steel Wire go out 3+9+15 again by multi-functional twisting machine in specification.
No matter be the all-steel cord of 3+6 or 3+9, or the all-steel cord of 3+9+15, product must just can be finished through multiple devices through several procedures, complex manufacturing, and not only production cost is higher, and the control ratio to product quality is difficult in the production process.
Summary of the invention
The objective of the invention is to: the operation that exists in producing at the all-steel cord mode of production of present existing 3+6,3+9 and 3+9+15 specification is many, complex process and product quality control ratio be the practical problem of difficulty, provides a kind of and produces 3/8 or 3/9 or the production method of similar all-steel cord.
The object of the present invention is achieved like this: a kind of production method of all-steel cord is characterized in that: get 11～12 Loosen up wire wheel that are tied with steel wire and place on the cradle of twisting machine; Steel wire Loosen up wire wheel unwrapping wire from the cradle, wherein: place internal layer by leading block with three, remaining evenly places skin by leading block; The Loosen up wire wheel that the start rear arm drives on the cradle rotates synchronously along equidirectional, and simultaneously, described steel wire all passes through the even unwrapping wire of locating hole, and is all-steel cord by identical pitch with ectonexine steel wire twisting, is batched by Receiving wire wheel then.
The diameter of producing the individual wire of all-steel cord is 0.20～0.38mm, and pitch is 12～18mm.
The invention has the advantages that: all place on the cradle of same twisting machine owing to will produce the used Loosen up wire wheel that is tied with steel wire of all-steel cord, the Loosen up wire wheel that the start rear arm drives on the cradle rotates synchronously along equidirectional, the inner core of all-steel cord can be formed according to identical pitch in one procedure synchronously with outer, not only reduced production process, alleviated labour intensity, reduce production cost, and improved the quality of product.
Description of drawings
Fig. 1 is a production method schematic diagram of the present invention;
Fig. 2 is the all-steel cord schematic cross-section of 3/8 specification.
Among the figure: 1, Loosen up wire wheel, 2, cradle, 3, steel wire, 4, leading block, 5, locating hole, 6, all-steel cord.
The specific embodiment
Accompanying drawing discloses production method of the present invention without limitation, and the all-steel cord schematic cross-section that adopts 3/8 specification of this method production, and the invention will be further described below in conjunction with accompanying drawing.
Embodiment 1
Fig. 1 is the production method schematic diagram of 3/8 all-steel cord, and as seen from the figure: the diameter of selecting individual wire earlier is that 11 Loosen up wire wheel 1 that are tied with steel wire 3 of 0.20～0.38mm place on the cradle 2 of twisting machine; With steel wire 3 Loosen up wire wheel 1 unwrapping wire from the cradle 2, wherein: place internal layer with three by leading block 4, remaining evenly places skin by leading block 4 then; Just start after above-mentioned preparation is finished, the Loosen up wire wheel 1 that the start rear arm drives on the cradle 2 rotates synchronously along equidirectional, simultaneously, described steel wire 3 is all by the 5 even unwrapping wire of the locating hole on the location-plate, and be all-steel cord 6 by identical pitch with ectonexine steel wire twisting, batch by Receiving wire wheel then.During concrete enforcement, individual wire is all-steel cord 6 according to the pitch of 12～18mm by twisting.
Embodiment 2
The production method of 3/9 all-steel cord is: the diameter of selecting individual wire earlier is that 12 Loosen up wire wheel 1 that are tied with steel wire 3 of 0.20～0.38mm place on the cradle 2 of twisting machine; With steel wire 3 Loosen up wire wheel 1 unwrapping wire from the cradle 2, wherein: place internal layer with three by leading block 4, remaining evenly places skin by leading block 4 then; Just start after above-mentioned preparation is finished, the Loosen up wire wheel 1 that the start rear arm drives on the cradle 2 rotates synchronously along equidirectional, simultaneously, described steel wire 3 all passes through locating hole 5 even unwrapping wire, and be all-steel cord 6 by identical pitch with ectonexine steel wire twisting, batch by Receiving wire wheel then.During concrete enforcement, individual wire is all-steel cord 6 according to the pitch of 12～18mm by twisting.
The main performance of the all-steel cord of producing according to production method of the present invention obviously is better than traditional 3+6,3+9, the all-steel cord of 3+9+15 specification, it is bigger that the product of producing according to the present invention and the product of equal Unit Weight are compared tensile strength, the tyre capacity of producing with the steel cord of equivalent weight is bigger, better with the rubber adhesion force rate, product stability is better.All-steel cord with 3/8 specification is an example, and with traditional 3+6,3+9, the all-steel cord of 3+9+15 specification compares, every index such as following table:
| Specification | Tensile strength (N) | Rubber adhesion power (N) | Stability (circle/week) |
| 3+6 | 1500 | 570 | 0.5 |
| 3+9 | 1210 | 370 | -0.5 |
| 3+9+15 | 2550 | 520 | 0.25 |
| 3/8 | 3000 | 650 | 0.05 |
As seen from Figure 2, the inner ring of the all-steel cord of 3/8 specification is the heart yearn that three steel wires form, and eight steel wires have been wrapped up in the outer ring.
