Embodiment Construction

[0021] Such as Figure 1-6 As shown, it is a schematic diagram of the overall assembly of a low wind noise wire twisting die device of the present invention and a schematic view of the structure of each component. The device includes two rotatable inner dies 1, a first fixed outer die 2, a second Two fixed outer dies 3, adjusting torque friction plates 4 and adjusting torque bolts 5, the inner rings of the first fixed outer die 2 and the second fixed outer die 3 are semi-circular, and the two form a Complete ring, the outside of the second fixed outer die 3 has a protrusion 31 for installing the adjusting torque bolt 5, and two semi-circular rotatable inner dies 1 also form a complete circle The ring is arranged in the ring formed by the first fixed outer die 2 and the second fixed outer die 3, and the inner die 1 can be rotated so that the first fixed outer die 2 and the second fixed outer die 3 The center of the formed ring is a shaft that can rotate freely. After the two r...

Abstract

The invention relates to a passive lead stranding die mold device with low wind noise, consisting of a rotatable inner die mold, a fixed outer die mold , a torsional moment adjustable friction plate and a torsional moment adjustable bolt, wherein the fixed outer die mold comprises a first fixed outer die mold and a second outer die mold, the rotatable inner die mold realizes free rotation by taking the center of the fixed outer die mold as an axle, and the thread pitch of screw thread and the groove depth of the rotatable inner die mold can be set according to the pitch value of an outer layer and the protruded height of the stranding lead with low wind noise; and the passive lead stranding die mold device has the advantages of flexible rotation, adjustable friction force, favorable rotating symmetry and the like. The passive lead stranding die mold device with low wind noise is used as a lead outlet die mold of a stranding machine and can be used for producing leads with low noise.

Description

technical field [0001] The invention relates to the field of electric wire manufacturing, in particular to a passive low-wind noise wire twisting and pressing die device. Background technique [0002] With the development of the economy and the progress of the society, people's awareness of environmental protection has gradually increased, and the requirements for the living environment have become higher and higher. The noise impact of transmission lines has increasingly become an environmental problem that attracts attention. Therefore it is very necessary to develop a molding device capable of twisting low-wind noise conductors. Such as Figure 7 As shown, the low wind noise conductor is a special conductor for overhead transmission lines. Its interior is an ordinary circular conductor, and the outermost conductor is a monofilament conductor with a trapezoidal cross-section, and the height of some monofilaments is higher than that of other structural units. The wire is f...
