Technical field

The utility model relates to a kind of stranding machine, and device is turned round in giving of using on especially a kind of stranding machine, and specifically a kind of stranding machine that is used for the odd-shaped cross section wire rod gives with the special-shaped line single line turns round device.

Background technology

As everyone knows, stranding machine is a requisite infrastructure device during power cable is produced.For a long time, non-directional because employed wire rod is circular cross-section, therefore, single guide wheel only need be installed on the stranding machine can finish stranded conductor and turn round the needs of making shape.

Only year along with the continuous growth of power industry and electrical demands, in order to improve ability to transmit electricity, reduce the wastage, reduce the space between the lead, improve the energising ability, people have solved this problem preferably by the lead of design odd-shaped cross section, are a kind of common novel conductive wires as the trapezoid cross section lead, this class lead is twisting when system, must make each strand lead merge the back by the angle of setting and form complete circular cross-section and twist and turn round.Method at present commonly used be with the circular cross-section line by squeezing drawing-die, directly enter to twist in the plying mould and turn round, this method not only makes the stranding machine complex structure, and badly influences machinery, the electric property of lead.Therefore, for a long time,, cause the production of odd-shaped cross section cable to be had a strong impact on, can't satisfy the needs of electric power industry development owing to there be not suitable giving to turn round device.

Summary of the invention

The purpose of this utility model be at present owing to there is not suitable odd-shaped cross section lead to give the problem of turning round guiding device and can't producing qualified profiled-cross-section cable, design and a kind ofly can enter the stranding machine that gives in the twisting die tool according to conductor cross-section Adjusting Shape lead and give with the special-shaped line single line and turn round device.

The technical solution of the utility model is:

A kind of stranding machine gives with the special-shaped line single line and turns round device, comprise wire-crossing wheel frame 16, go up wire carrier 18 and descended wire carrier 19, going up wire carrier 18 is installed on the little axle 17, descended wire carrier 19 to be installed on the little axle 17 ', little axle 17,17 ' is installed on the wire-crossing wheel frame 16, went up wire carrier 18 and descended between the wire carrier 19 to form one with wait to turn round the through hole 32 that the wire rod cross sectional shape matches, it is characterized in that described wire-crossing wheel frame 16 links to each other with an end of the rotating shaft 13 of passing noseplate 15, rotating shaft 13 is provided with ball head structure 34, the part of ball head structure 34 is arranged in the ball-and-socket on the noseplate 15, its other end is arranged in the ball-and-socket on the gland 14, gland 14 and noseplate 15 link to each other by connecting bolt, and rotating shaft 13 is provided with perforation, the cable-through hole 33 that communicates with through hole 32.

Described wire-crossing wheel frame 16 links to each other by screw thread with an end of rotating shaft 13.

On the described little axle 17,17 ' bearing 29,29 ' is installed, describedly went up wire carrier 18 and descended wire carrier 19 to be installed on the described bearing 29,29 '.

The beneficial effects of the utility model:

The utility model has solved the problem of correctly going into mould of various cross sections lead, adopts spherical structure, not only adjustable turn over angle, and can adjust luffing angle, lead is entered by the angle of setting give in the twisting die.

The utility model is twisted into shape according to the giving of shaped conductor that the difference of the shape of the through hole between the wire-crossing wheel up and down can be designed to trapezoidal, triangle, Z-shaped, pentagon, diamond-shaped cross-section.

The utility model is simple in structure, designs ingeniously, easy to adjust, quick, helps enhancing productivity.
