Background technology
In the production of electric wire, twist kind equipment processed and occupy very important status.According to the stranded form of twisted wire not
With, as regular stranded capital equipment, cage stranding machine, because the advantage of its uniqueness, is increasingly becoming production bare wire and cable
One of capital equipment of conductor wire core.When twisted wire is when stranded, along with the rotation of relatively cage, single line be wound in a helical pattern with
Basic circle is on the cylinder of diameter, and single line can bend everywhere, and single line is also about own axes and produces torsional deflection simultaneously,
The angle reversed in one pitch is 360 degree.The bending of single line and torsional deflection, make twisted wire produce internal stress, affect twisted wire matter
Amount.Due to twisted wire structure, flexural deformation when single line is stranded is inevitable, and the problem of torsional deflection then can be passed through
Back twist technique is used to solve.The cage size of common back-twisting mechanism is relatively big, is arranged on the twisted wire on cradle-type pay off rack also
The heaviest, when cage makees high speed rotating, huge centrifugal intertia force can be produced.Therefore, the supporting form of cradle-type pay off rack is non-
The most important, its fine or not direct reaction quality of cage performance.The back twist axle that normally used pay off rack left end is connected is not only
Cage to be born rotate time drum and pay off rack produced by centrifugal intertia force, back twist campaign to be transmitted.Due to whole mechanism
Poor rigidity, under the effect of alternate stress, arises that connecting bolt loosens, and the support holes at pay off rack two ends becomes
Shape, becomes horn-like, and equipment often wants shutdown maintenance, and production efficiency is low.
