Description
Technical field
The utility model relates to a kind of stress of eliminating steel cord stress and reverses releasing device.
Background technology
The steel cord is to twist with the fingers moulding by multifilament by the strander strand, monofilament is wrapped on the Loosen up wire wheel in the twisting process, strand is twisted with the fingers the steel cord of moulding then around to Receiving wire wheel, be that steel cord two ends all can not freely be rotated and subtracted sth. made by twisting in the twisting process, so there is Residual torsion in the steel cord inevitably and distorting stress is arranged.The concrete implication of Residual torsion is: the steel cord of specific length, and when the one end is maintained fixed, when the other end is let alone to rotate freely, the revolution that is rotated.When Residual torsion during greater than certain value, though can reduce a large amount of Residual torsion values, can not remove the residual stress of steel wire for a full due by traditional Killing unit and swage, the steel cord just becomes defective work, and the yield rate of product is low.
Summary of the invention
The utility model provides a kind of stress to reverse releasing device, and it can handle the defective steel cord of Residual torsion value between 2.5--5 commentaries on classics/6m, eliminates its stress, makes it to become qualified products.
The technical solution of the utility model is as follows: a kind of stress reverses releasing device, it mainly is made up of motor, reduction box and swivel mount, swivel mount comprises rotating disk and perpendicular to the fixed mount of rotating disk, the I-beam wheel Unreeling seat is installed on the fixed mount, the main shaft of I-beam wheel Unreeling seat parallels with rotating disk, the running of driven by motor reduction box, reduction box drives dial rotation.
In the utility model, be provided with guide wheel and conduit around the Unreeling seat, the I-beam wheel Unreeling seat is provided with the tension force self-checking device.
Described tension force self-checking device comprises arm of force seat and has the flexible element of damping block, arm of force seat is fixed on the fixed mount by fulcrum, arm of force seat is provided with three support arms, be fixed with escapement on one of them support arm, another support arm presets device with tension force and is connected, and the 3rd support arm is connected with flexible element one end, and the flexible element other end is fixed on the fixed mount, flexible element is provided with damping block, and damping block contacts with Unreeling seat main shaft rubbing surface; Described flexible element is a chain.
Described tension force presets device and comprises extension spring and nut-screw pair, and nut is fixedlyed connected with fixed mount, and extension spring is connected between the support arm and screw rod of arm of force seat; Described nut is fixed on the guide wheel shaft that fixed mount is provided with.
After adopting technique scheme, swivel mount is rotated at a slow speed by driven by motor, Unreeling seat also rotates thereupon, be that Unreeling seat rotates in the plane perpendicular to steel cord wire direction, when under the tractive force effect of the steel cord on the I-beam wheel at Wrapping machine during unwrapping wire, on one side the wire on one side of steel cord is rotated, just residual torsional stress can be discharged, make the Residual torsion value be reduced to normal range (NR), make defective steel cord change into qualified products, improved yield rate.Motor can just change, and also can reverse, and decides according to the Residual torsion situation of steel cord, and promptly motor rotates in the opposite direction according to turning round to the driven rotary frame of Residual torsion, and distorting stress is discharged.The rotating speed of swivel mount also can be regulated by Electric Machine Control, and residual torsional stress is big more, the also corresponding rev up of swivel mount.
