Description
Technical field
The present invention relates to a kind of bead winding machine, belong to the wrapping machine technical field.
Background technology
In the tire production field, in order to strengthen integrated support rigidity and the reliability of tire, need to be provided with wire loop in tire.Existing wire loop be by a steel wire through being entwined, its cross section is hexagon, is straight between steel wire and steel wire and substantially is parallel to each other, and is filled with rubber between steel wire and steel wire.
Aircraft tyre normally uses under pressure, top load, large deformation and extremely strong impact load in high.When existing meridian aviation tyre used under bearing top load, large deformation situation, tyre bead portion was subject to very large imposed deformation, impelled rubber inner heat of giving birth under the viscoplasticity effect, caused tyre temperature to raise.Repeatedly produce and subdue greatly easily generation tyre bead portion damage phenomenon of distortion, the damage of tyre bead portion is generally near wheel rim top, be easy to produce with on every side rubber interface in the anti-package termination of carcass ply and peel off, be easy between the interface of wire loop or gum filler and casing ply generation delamination or the cord phenomenon that fractures.Thereby greatly reduce the endurance quality of tyre bead, cause the tyre bead delamination, bulge of tire when serious, even the tyre bead blasting phenomena occur.
Summary of the invention
The objective of the invention is to use under pressure, top load, large deformation and extremely strong impact load in high in order to solve tire that existing wire loop makes, be easy between the interface of wire loop or gum filler and casing ply to occur delamination or the cord problem of phenomenon that fractures, and then a kind of bead winding machine is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of bead winding machine, comprise: frame, main drive, deposit silk and the location of steel wire tension control device and wire loop clamps tumbler, described main drive is arranged on a side of frame, deposit silk and steel wire tension control device and be arranged on the top of main drive, the location of wire loop clamps tumbler and is arranged on the opposite side of frame.
The present invention has the following advantages: bead winding machine of the present invention is relatively simple for structure, manufactures than being easier to.Between the wire loop that is wound around is inside and outside two-layer, the direction of rotation is opposite each other, and the steel wire of one deck is left-handed, and the steel wire of another layer is exactly dextrorotation, need not filled rubber between steel wire and steel wire, can be directly used in the making of tire.The tire that the wire loop of doing with bead winding of the present invention mechanism is produced is adapted at using under pressure, top load, large deformation and extremely strong impact load in high.To subdue greatly its tyre bead portion of distortion not fragile yet even repeatedly produce, and delamination or the cord phenomenon that fractures can not occur between the interface of wire loop and casing ply yet, greatly improved the durability of tyre bead.
