Automatic untwisting stranded wire die
Technical Field
The invention relates to the technical field of stranded wire dies, in particular to an automatic untwisting stranded wire die.
Background
The existing equipment for producing stranded wires has stress, namely torsion, in the opposite rotation direction of the finished stranded wire monofilaments due to the working principle and characteristics of the equipment. The existing stranded wire production equipment adopts a fixed die, three main components forming the die, namely a die core, a die sleeve and a die box are fixedly arranged, a single wire of a stranded wire generates torsion due to the rotation of the equipment and is gathered at a die twisting position, and the die is fixed and cannot release the torsion, so that stress is formed inside a finished stranded wire. The stress is regularly accumulated, released, accumulated and released along with the production of the stranded wire, so that the internal stress of the finished product is large or small, and the final finished product has poor appearance and is reciprocated in an arc-shaped rule. The uncertainty of the stress in the inner part can cause the uncertainty of the final service life of the inner part. In particular, products such as a dropper wire for an electrified railway are reciprocated by vibrations in a working environment. Under such conditions, the greater the stress, the shorter the service life.
Disclosure of Invention
The invention provides an automatic untwisting stranded wire die which can solve the technical problems that the finished product appearance is poor and the service life is short due to the fact that the existing stranded wire cannot release torsion.
Its technical scheme is such, and automatic back twist reverse stranded conductor mould, including mould core, mould cover and mould box, the mould core install in the mould cover, the mould cover is established and is arranged in the mould box, its characterized in that:
the mould still includes supporting seat, slewing mechanism and elastic mechanism, the mould cover is installed in the supporting seat through slewing mechanism, makes the mould cover can be in the rotation in plane of perpendicular mould dabber line direction, the storage tank has been seted up to the mould box, the supporting seat install in the storage tank and can slide along mould dabber line direction, the supporting seat be located the both sides terminal surface of mould dabber line direction pass through elastic mechanism with two inside wall elastic connection of storage tank.
Furthermore, slewing mechanism includes the bearing, the supporting seat with the both ends of mould cover are respectively through the bearing cooperation.
Furthermore, the elastic mechanism comprises a spring and guide pillars, a pair of guide pillars which are distributed up and down and are arranged in parallel with the axis of the mold core are fixed on two sides of the inner cavity of the accommodating groove respectively, the spring is sleeved after the guide pillars penetrate through the end faces of two sides of the supporting seat, and two ends of the spring are elastically abutted to the supporting seat and the mold box respectively.
Further, the mold sleeve comprises two half bodies, and the mold core is embedded into the two half bodies and then locked through bolts.
According to the automatic untwisting stranded wire die, the die sleeve is mounted on the supporting seat through the rotating mechanism, so that the die sleeve can rotate in a plane vertical to the direction of the central axis of the die, and after the die core and the die sleeve rotate synchronously, the torsion of a stranded wire can be eliminated, the appearance of a stranded wire finished product is improved, and the service life of the stranded wire is prolonged; in the speed adjustment process of the equipment stranded wire, the supporting seat slides along the axis direction of the mold core under the driving of the stranded wire, the stranded point can be quickly found, the two side end faces of the supporting seat positioned in the axis direction of the mold core are elastically connected with the two inner side walls of the accommodating groove through the elastic mechanisms, and the mold core and the mold box are maintained at the stranded point through the elastic action of the elastic mechanisms on the two sides.

Detailed Description
As shown in fig. 1, the automatic untwisting wire mold comprises a mold core 1, a mold sleeve 2, a mold box 3, a support seat 5, a rotating mechanism and an elastic mechanism; the mold sleeve 2 comprises a front half body 2a and a rear half body 2b, and two sides of the mold core 1 are embedded into the front half body 2a and the rear half body 2b and then locked through bolts 8; the mold sleeve 2 is arranged in the mold box 3; the mold box 3 is connected with the bracket to keep fixed, the mold box 3 is provided with an accommodating groove, the support seat 5 is arranged in the accommodating groove, and the bottom surface and the two outer side walls of the support seat 5 are respectively in sliding fit with the bottom surface and the two inner side walls of the accommodating groove, so that the support seat 5 can slide along the axial direction of the mold core 1; the die sleeve 2 is arranged on the supporting seat 5 through a rotating mechanism, so that the die sleeve 2 can rotate in a plane perpendicular to the axis direction of the die core 1, specifically, the rotating mechanism comprises a bearing 4, and the supporting seat 5 is matched with two ends of the die sleeve 2 through the bearing 4 respectively; the both sides terminal surface that supporting seat 5 is located 1 axis direction of mould core passes through elastic mechanism and two inside wall elastic connection of storage tank, and is concrete, and elastic mechanism includes spring 7 and guide pillar 6, and the inner chamber both sides of storage tank respectively are fixed with a pair of guide pillar 6 that distributes from top to bottom, with 1 axis parallel arrangement of mould core, and the cover is equipped with spring 7 behind the guide pillar 6 runs through the both sides terminal surface of supporting seat 5, and spring 7's both ends respectively with supporting seat 5, 3 elastic butt of mould box.
