Abstract

A one-line type steel cord stranding machine comprises an air brake system, a central shaft, a motor, fly wheel discs, a support platform, a guide wheel, a winding wheel, a traction wheel, a strander, a cord collecting tip, a guide wheel disc and a cord distributing disc 14. The fly wheel discs are respectively arranged at two ends of the central shaft, and the two fly wheel discs extend out to be connected with ceramic wheels. The central shaft and the air brake system connected with the central shaft are both arranged at the middle portion of the support platform. The winding wheel, the guide wheel, the guide wheel and the strander are sequentially arranged at the left end of the support platform, and the cord collecting spout, the guide wheel disc and the cord distributing disc are sequentially arranged at the right end of the support platform. Compared with the prior art, the one-line type steel cord stranding machine has the advantages of simple structure and convenience in use. The one-line type steel cord stranding machine has small rotation inertia, and extraction force of each steel wire or strand from an unwinding bobbin can be essentially equal during a stranding process. Differences of increases of friction during a threading process is small, stranding tension is even, and broken wires and fractures appear in the stranding process of the steel wires can be timely monitored.

Description

One-line steel cord strander

Technical field

The utility model relates to steel cord production equipment technical field, is specifically related to a kind of one-line steel cord strander.

Background technology

The steel cord will bear bend tension composite alternating load and shock loading as the reinforcing material of tire, and this just requires the steel cord will satisfy high strength, antifatigue, requirement such as shock-resistant.The steel cord is in the twisting process, steel wire is made uniform circular motion by the rotary body drive of twisting device, while is pulled the device drive again and at the uniform velocity advances, make steel wire in thigh, in cord, be the cylindrical screw line states, with regard to this point, various strander all is the same, produces the steel cord with tubular stranding machine in early days, afterwards evolving development rope skipping formula strander.The rotary body of tubular stranding machine is long tube, but high speed rotating, Loosen up wire wheel has only one at tube exterior, and all the other are all at tube interior, so have many windows that are used for changing I-beam wheel on tube wall.Steel wire arrives the twisted point by pre-former and is twisted into thigh along the conduit of tube wall inner edge (interior threading) or outer rim (outer threading), by the traction wheel guiding, through straightener, is wound onto on the Receiving wire wheel then.The rotary body of this tubular stranding machine has a lot of shortcomings, and the one, rotary inertia is big, has limited the raising of rotating speed; The 2nd, draw ratio is big, is difficult to the dynamic balancing that reaches good; The 3rd, have many windows, reduce the steel cord strength; The 4th, limited the capacity and the quantity of I-beam wheel.Rope skipping formula strander, its rotary body are two arc steel bands, on the arc steel band conductor loop are arranged, and are convenient to steel wire or strand pass through.Its operation principle is identical with tubular stranding machine, but rope skipping formula strander has a tangible weakness: steel wire was sinusoidal wave track operation before twisting, cause the route that twisted point passes through and the quantity of turning point from first Loosen up wire wheel, than second until last, mutually very big-difference is arranged, the centrifugal force of each root steel wire and frictional force are very inconsistent, and the twisting tension fluctuation is very big, influence the twisting quality.

The utility model content

The purpose of this utility model is exactly the defective that exists at prior art, and a kind of one-line steel cord strander is provided.

Its technical scheme is: comprise that air braking system, central shaft, motor, Flywheel disc, saddle, directive wheel, take-up pulley, traction wheel, Killing unit, line concentration are chewed, guide wheel disk, noseplate.The two ends of described central shaft are separately installed with Flywheel disc, the wire-crossing wheel of going out to be connected with of two Flywheel discs, central shaft and the coupled straight air brake system motor of unifying all is installed on the middle part of saddle, described saddle left end is provided with take-up pulley, directive wheel, traction wheel and Killing unit in turn, and described saddle right-hand member is provided with in turn that line concentration chews 12, guide wheel disk and noseplate.

Wherein, the unify outside of motor of described central shaft, Flywheel disc, straight air brake system is provided with protection cabinet.

The utility model has advantage simple in structure, easy to use compared with prior art.Its rotary inertia is little, each root steel wire or the power of drawing strand from the Loosen up wire wheel can be accomplished basic identically in the twisting process, and the frictional force increment in the threading process differs seldom, and the twisting warp tension ratio is more even, and can monitor the fracture of wire that steel wire occurs, port phenomenon in the twisting process in good time.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

The specific embodiment

With reference to Fig. 1, a kind of one-line steel cord strander comprises that air braking system 1, central shaft 2, motor 3, Flywheel disc 4, saddle 5, directive wheel 6, take-up pulley 7, traction wheel 9, Killing unit 10, line concentration chew 12, guide wheel disk 13, noseplate 14.The two ends of described central shaft 2 are separately installed with Flywheel disc 4, the wire-crossing wheel 11 of going out to be connected with of two Flywheel discs 4, the middle part that central shaft 2 and coupled air braking system 1 and motor 3 all are installed on saddle 5, described saddle 5 left ends are provided with take-up pulley 7, directive wheel 6, traction wheel 9 and Killing unit 10 in turn, and described saddle 5 right-hand members are provided with in turn that line concentration chews 12, guide wheel disk 13 and noseplate 14.The outside of described central shaft 2, Flywheel disc 4, air braking system 1 and motor 3 is provided with protection cabinet 16.

During operation, motor 3 starts, Flywheel disc 4 rotates with central shaft 2, take-up pulley 7 is installed in saddle 5 left ends, Loosen up wire wheel is placed on the saddle right side and fixes, the many single steel wire 15 of even tension are through noseplate 14, guide wheel disk 13 arrives twisted point line concentration and chews 12, the tension force of steel wire is regulated by guide wheel disk 13 at this, because line concentration is chewed 12 and is not rotated, and wire-crossing wheel 11 is being with steel tendon to rotate with n speed with rotary body, thereby steel tendon is at right side wire-crossing wheel 11, line concentration is chewed 12 these sections and is chewed 12 ends for line concentration and fix, the rotation of right side wire-crossing wheel 11 ends, Flywheel disc 4 revolutions move a week, and steel tendon is just finished twisting for the first time, steel tendon is got back on the guide roller 11 of left side noseplate 4 through detouring from right side noseplate 4 rotary bodies after the first time twisting, then by Killing unit 10 to traction wheel 9.Because Killing unit does not influence strand or the lay pitch of cord, therefore traction wheel 9 ends of 11 sections of the guide rollers of traction wheel 9, left side noseplate 4 can be seen to fix the rotation of guide roller 11 ends, make it to finish twisting for the second time, like this, the rotary body revolution moves a week, and cord forms two lay pitch.The at last hub disk of plying back steel cord 8 is gone into take-up pulley 7.
