Summary of the invention

The purpose of this utility model provides a kind of outside unwrapping wire and each three times of stranding machine of one group of inner unwrapping wire.

To achieve these goals, the utility model adopts following technical scheme:

The twisted wire principle: outside draw drum is emitted line, crosses the rotation steel band by guide wheel, and simultaneously the line of emitting with inner draw drum passes wire twister, forms first lay at A point, crosses outside tension at B point formation second lay, at C point formation the 3rd lay.

The back twist principle: suppose that outer draw drum maintains static, the A point is for fixing, and the rotation steel band is always toward rotation on the one hand.Then, when line is crossed guide wheel, if+1 strand, crossing 2 formation of guide wheel-1 strand so.Two laies add up to 0, are directly and put.Inner unwrapping wire is a direct amplifier system, forms first lay at the A point.This moment, the back twist rate of two line pair twists was 100%.If simple lay back twist part partly opposite with pair twist to and during constant speed, then back twist apart from be the simple lay lay remove in the simple lay lay add the multiple twin lay and, if require to make back twist rate and the lay that needs, partly place the speed of steel band and the linear velocity of a pair of twisted wire as long as change the simple lay back twist.

Three times of stranding machines, it comprises simple lay back twist part and pair twist part.The simple lay back twist partly comprises outside unwrapping wire and inner unwrapping wire, the unwrapping wire of outside draw drum connects three guide wheels arranging in order by cylinder, fix a guide wheel before and after the main shaft of center cable-through hole respectively, the two ends of rotation steel band connect a guide wheel, and guide wheel is connected with the main shaft of center cable-through hole two; Five guide wheels that the unwrapping wire order of connection on the inner draw drum is arranged, the last guide wheel center of being fixed on is provided with the front end of the main shaft two of cable-through hole two; Main shaft two rear ends are fixed with the guide wheel group of three guide wheels arranging in order, and last guide wheel is got guide wheel of wheel connection by drawing, and draw and get two guide wheels of wheel connection; Guide wheel connects guide wheel by main shaft, and a guide wheel is fixed at the two ends of rotation steel band respectively, connects by four guide wheel take-up reels.

Four guide wheels that are linked in sequence are formed inner tension control, and line connects cylinder by four guide wheels.

Three guide wheels are formed outside tension control, and the line that is fixed on first guide wheel is connected with sprocket wheel by latter two guide wheel.

Tension control balancing weight is to carry out counterweight according to the quality and the speed of line.

Motor starting drives the sprocket wheel rotation, and sprocket wheel directly drives wire reel and rotates.With drum hoisting frame tighten, the rotation by wire reel is done the drum hoisting frame and is moved up and down through guide wheel for one end of the steel wire of the winding on the wire reel.Two guide wheels in the lifting swing arm clamp steel wire, thus the trend of restriction steel wire.Two swing arms on the lifting supporting seat are at the effect lower swing of external force, thus the direction of change drum hoisting frame.

Advantage of the present utility model is as follows: the quality of twisted wire is good, and speed is fast.
