Description

Stranding machine porcelain guide twisting bow

Technical Field

The utility model relates to a hank bow field, concretely relates to hank line machine porcelain is led hank bow.

Background

The wire twisting machine is also known as a high-speed wire twisting machine/wire bundling machine/wire-mixing machine, and is widely applied to twisting of various soft/hard conductor wires (copper wires, enameled wires, tinned wires, copper-clad steel, copper-clad aluminum and the like) and electronic wires. The twisting bow is used as a core component of a twisting machine, the function of the twisting bow is important, and the twisting bow has an important influence on the quality of a twisted wire. The line porcelain eye of crossing on traditional stranding machine hank bow plays the groove easily under the scraping of copper line for a long time, will scratch the copper line after playing the groove, produces the burr. In order to solve the technical problem, chinese patent No. CN206921585U discloses a wire twisting machine twisting bow, which includes a guide wheel assembly on the twisting bow, wherein the guide wheel assembly includes a bracket fixedly connected to a twisting bow body, a first guide wheel rotatably connected to the bracket, and a pressing cover hinged to the bracket, wherein a locking assembly for locking the pressing cover to the bracket is disposed at a position corresponding to one end of the pressing cover away from a side of the bracket rotatably assembled and a corresponding position on the bracket, and the wire twisting bow has an advantage of being conveniently threaded on the twisting bow.

The above patent adopts the guide wheel assembly to lead, and although the problems of the traditional thread passing porcelain eye friction and threading difficulty are solved, the guide wheel assembly in the patent has a larger gap, so that the thread is easily clamped in the twisting process, and the practical application is not ideal, and the technology is not widely used in the market at present.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a hank bow is led to stranding machine porcelain, during mainly used copper line stranded conductor technology, prevent to scrape colored copper line and card line, lead the subassembly through setting up the porcelain on the hank bow body, realize the seamless butt joint of porcelain guide pulley, avoid among the prior art the great card line problem that causes in guide pulley subassembly gap.

The purpose of the utility model is realized through the following technical scheme:

a porcelain guide twisting bow of a wire twisting machine comprises a twisting bow body and a plurality of porcelain guide assemblies which are sequentially fixed on the twisting bow body along the axial direction;

the porcelain guide assembly consists of a base frame, a first porcelain guide wheel and a second porcelain guide wheel, wherein the first porcelain guide wheel and the second porcelain guide wheel are mounted on the base frame through a rotating shaft and meet the requirement that the wheel edges of the first porcelain guide wheel and the second porcelain guide wheel are tangent to each other;

a circular protection disc is coaxially fixed on each of the two inner sides of the second ceramic guide wheel and is tangent to the central shaft of the first ceramic guide wheel;

and a traction hole is formed between the central shaft and the concentric shaft of the second porcelain guide wheel.

Compare with the porcelain guide pulley that traditional symmetry set up, this scheme sets up two guide pulleys tangent, simultaneously in order to avoid the tangent border of two porcelain guide pulleys to cause scratch or card line copper line (or other lines), this scheme adds a circular protection plate tangent with another porcelain guide pulley center pin at one of them porcelain guide pulley inner wall, the benefit of this design lies in the relative position that can fix two porcelain guide pulleys, as limiting displacement, avoid two porcelain guide pulleys to take place the aversion phenomenon, secondly shift to the bottom with the seam of tangent formation, thereby reduce the contact probability of copper line and looks joint-cutting, thereby very big reduction card line problem, also can avoid tangent seam to rotate the in-process and scrape the flower copper line.

Furthermore, a circle of arc-shaped or semicircular lead groove is formed in the central shaft and the concentric shaft along the axial surface. The arc-shaped or semicircular lead groove is arranged, so that the smoothness can be improved, the friction is further reduced, and the patterned copper wire is prevented from being scraped.

Furthermore, the circular protection disc is made of ceramic materials, the circular protection disc, the second ceramic guide wheel and the concentric shaft are integrally formed by integral die sinking, and the integral structure is more compact by adopting integral die sinking, so that seamless butt joint is realized.

Furthermore, the axial length of the first porcelain guide wheel and the second porcelain guide wheel is equal, the circular protection disc is tightly attached to the inner wall of the first porcelain guide wheel on the side, and the design can play a good limiting role to avoid the first porcelain guide wheel and the second porcelain guide wheel from shifting left and right.

Further, the outside of first porcelain guide pulley, second porcelain guide pulley is coaxial respectively to be provided with the pivot, the pivot diameter is less than the diameter of center pin and concentric shaft far away, and this scheme is fixed first porcelain guide pulley, second porcelain guide pulley on the base frame through the pivot promptly.

Further, the base frame is fixed on the hinge bow body in a screw or bonding mode.

Compared with the prior art the beneficial effects of the utility model are that:

(1) the two ceramic guide wheels are tangent to each other and provided with the protective disc, so that a gap between the two ceramic guide wheels is eliminated, and wire clamping in a wire stranding process can be avoided;

(2) the gap formed by the butt joint of the two porcelain guide wheels is transferred to the bottom through the round protective disc, so that the contact between a copper wire and the gap is greatly reduced, and trace displacement embossing or scraping copper wires in the rotation process of the porcelain guide wheels can be avoided.
