Description
Technical field
The utility model relates to the predeformation controlling organization in the radial tyre steel cord production equipment, refers to a kind of high elongation steel cord predeformation controlling organization particularly.
Background technology
In the production process of radial tyre steel cord, especially when producing height elongation steel cord, need carry out sufficient mechanically deform to steel wire by pre-former, eliminate the stress in the steel wire, improve the twisting quality of strand.At present, in radial tyre steel cord production equipment, the pre-former that is used for high elongation steel cord adopts following structure mostly: three needle rollers are set on the wire-crossing wheel seat, and these three V-shaped layouts of needle roller are carried out flexural deformation by needle roller to the steel cord.The bearing capacity of this V-arrangement needle roller structure is less, running stablize relatively poor, the predeformation of steel cord is wayward, when producing high elongation steel cord, tend to the situation that steel cord percentage elongation is less than normal, the steel Cord thickness is also less than normal takes place, cause the wearing and tearing of steel cord more, stress-retained big, loosening degree twisting higher, strand is second-rate.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of height simple in structure, easy to operate, that can effectively control mechanically deform to extend steel cord predeformation controlling organization.
At above-mentioned purpose, the height elongation steel cord predeformation controlling organization that the utility model is designed, comprise the wire-crossing wheel seat, lead-in wire terminal on the described wire-crossing wheel seat is provided with a guide roller, leading-out terminal on the described wire-crossing wheel seat is provided with a needle roller, wire-crossing wheel seat between described needle roller and the guide roller is provided with 2～4 band ditch bearing rollers, and the axial connecting line of described needle roller and immediate band ditch bearing roller and the longitudinal centre line of wire-crossing wheel seat are 35～50 ° of angles.
Further, described 2～4 band ditch bearing rollers are arranged in a linear, and each is 25～40 ° of angles with the axial connecting line of ditch bearing roller and the longitudinal centre line of wire-crossing wheel seat; Described band ditch bearing roller is provided with 3; Shortest spacing between the mistake line trenches of described adjacent band ditch bearing roller is 0.5～1 times a length of lay for steel cord.
Further, described guide roller is arranged in the arc regulating tank of lead-in wire terminal on the wire-crossing wheel seat; Described needle roller is installed in by needle bearing and deep groove ball bearing in the bearing block of leading-out terminal on the wire-crossing wheel seat, and described needle roller adopts Hardmetal materials to make, and its two ends of crossing line part profile are that arc surface, centre are the face of cylinder.
Advantage of the present utility model is: the design of band ditch bearing roller and guide roller makes the mechanically deform of steel cord obtain effective control; Band ditch bearing roller serves as deformation wheel, can effectively control the wearing and tearing of steel cord; Two ends are arc surface, middle line partial design excessively for the face of cylinder, make the line contact-making surface become the plane by former cambered surface, have controlled the rolling flip of steel cord effectively; The carbide alloy needle roller is fixed by needle bearing and deep groove ball bearing, and load is bigger, and running is stable.The height elongation steel cord predeformation controlling organization that the utility model is designed, simple in structure, easy to operate, can effectively control mechanically deform, the height elongation steel cord of its manufacturing, stress is eliminated relatively thoroughly, loosening degree is lower, steel cord percentage elongation is normal, and the twisting quality of high elongation steel cord strand is better.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Height elongation steel cord predeformation controlling organization shown in the figure, comprise wire-crossing wheel seat 1, lead-in wire terminal on the wire-crossing wheel seat 1 is provided with a guide roller 7, leading-out terminal on the wire-crossing wheel seat 1 is provided with a needle roller 2, wire-crossing wheel seat 1 between needle roller 2 and the guide roller 7 is provided with 3 band ditch bearing rollers 5, needle roller 2 and be 35～50 ° of angles near the axial connecting line of the band ditch bearing roller 5 of needle roller 2 and the longitudinal centre line of wire-crossing wheel seat 1,3 band ditch bearing rollers 5 are arranged in a linear, band ditch bearing roller 5 is fixed on the wire-crossing wheel seat 1 by screw 6, the axial connecting line of band ditch bearing roller 5 and the longitudinal centre line of wire-crossing wheel seat 1 are 25～40 ° of angles, and the shortest spacing between the mistake line trenches of adjacent band ditch bearing roller 5 is 0.5～1 times a length of lay for steel cord.Guide roller 7 is fixed in the arc regulating tank 11 of lead-in wire terminal on the wire-crossing wheel seat 1 by bearing 8, bolt 9 and nut 10; Needle roller 2 is installed in the bearing block of leading-out terminal on the wire-crossing wheel seat 1 by needle bearing 3 and deep groove ball bearing 4, and needle roller 2 adopts Hardmetal materials to make, and its two ends of crossing line part profile are that arc surface, centre are the face of cylinder.
Operation principle of the present utility model is as follows: the steel cord is successively by the needle roller 2 of 7,3 band ditch bearing rollers 5 of guide roller and carbide alloy, is installed in the guide roller 7 in the arc regulating tank 11 of lead-in wire terminal on the wire-crossing wheel seat 1, the inlet wire angle that can regulate the steel cord.Because the needle roller 2 and the axial connecting line of immediate band ditch bearing roller 5 and the longitudinal centre line of wire-crossing wheel seat 1 are 35～50 ° of angles, so can be 70～90 ° of angles with the longitudinal centre line of wire-crossing wheel seat 1 by the steel cord between them, can effectively control the mechanically deform of steel cord.Because the line excessively of the needle roller 2 of carbide alloy partly is the plane, roll so controlled the slippage of steel cord when being out of shape effectively, reduced the steel cord end product quality factors of instability.The steel cord that utilizes the designed height elongation steel cord predeformation controlling organization of the utility model to produce, stress is eliminated more thorough, and loosening degree is lower, and steel cord percentage elongation is normal, and the quality of steel cord has obviously improved.The utility model is simple in structure, and is easy to use, and processing and manufacturing easily is beneficial to promotion and implementation very much.
