Description

[Detailed Description of the Invention] The present invention relates to a compression-molded stranded wire plug containing reinforcing tape.

Compression-molded stranded wires are effective in producing long lengths of large-capacity superconductors and as pulse conductors because of their large size and ease of handling, processing, and wiring.

This conductor is manufactured by compressing a number of strands 1 stranded by a stranding machine as shown in Fig. 1. In manufacturing such a conductor, a plug is fixed to the tip of the stranding machine, the strands are guided along it and stranded, and then compression molding is performed by a roll at the tip of the plug. However, in a conductor having a structure in which a superconductor 3 is stranded around a tape-shaped core material 2 such as a reinforcing material as shown in Fig. 2, it is difficult to insert the core tape between the strands and strand them because the tape is flexible.

The present invention was made as a result of intensive research based on the above knowledge, and consists of a cylindrical base connected to the main shaft of the wire twisting machine, a truncated conical superconducting wire guide section formed following the base, and a superconducting wire guide section formed following the base. a superconducting wire alignment section that is sloped more gently than the guide section formed following the section, and a reinforcing tape guiding path is provided along the strand axis in the base section, the superconducting wire guide section, and the superconducting wire alignment section. This provides a plug for compression molding stranded wire processing containing reinforcing tape, which facilitates compression molding processing with reinforcing tape inserted therein.

The present invention will be explained below with reference to drawings showing one embodiment.

Fig. 3 is a plan view showing one embodiment of the present invention;
The figure is a side view thereof. Reference numeral 4 denotes a compression molded wire stranding plug (hereinafter referred to as the plug). 4 is a cylindrical base 5 connected to the main shaft of the wire stranding machine, and a cylindrical base 5 that is connected to the cylindrical base 5. A truncated conical superconducting wire guide section 6 formed in the form of a truncated cone, and a superconducting wire alignment section 7 formed subsequent to the superconducting wire guide section 6 and having a gentler slope than the superconducting wire guide section 6 are integrally formed. has been done.

A threaded portion 8 for connecting the plug 4 to the main shaft of the wire twisting machine is provided protruding from the base portion 5. Reference numeral 9 denotes a notched flat portion that engages a spanner when connecting or disconnecting.

The superconducting wire guide section 6 is a part that connects the cylindrical base 5 and the superconducting wire alignment section 7, receives the superconducting wire 3 sent while rotating, and guides it to the superconducting wire alignment section 7, and has a truncated conical shape. I am doing it. In order to improve the sliding of the superconducting wire 3, the slope of the truncated cone is formed to be large.

The superconducting wire alignment section 7 is a section that aligns the superconducting wires 3 sent from the superconducting wire guide section 6 and transfers them to the next compression step, and has a gentler slope than the superconducting wire guide section 5.

The plug 4 configured in this manner is provided with a reinforcing tape guiding path 10 for inserting the reinforcing tape along the stranded wire axis. As shown in FIGS. 5 to 7, this reinforcing tape guide path 10 has a base 5,
It has a flat cross-sectional shape passing through the superconducting wire guide section 6 and the superconducting wire alignment section 7. Also the 8th
9 to 9 show other examples of the reinforcing tape guide path 10, in which a guide groove with a rectangular cross section is formed along the stranded wire axis, as shown in FIGS. 10 to 12.

Further, the superconducting wire alignment section 7 includes a superconducting wire guide section 6.
As shown in FIG. 13, a tip part 11 is formed which is steeper than the alignment part 7 in the rolling direction of the superconducting wire, as shown in FIG. You can also do that. In order to perform compression molding effectively, it is desirable that the alignment portion 7 be made as thin as possible and that the tip portion 11 form an acute angle.

A method of using the plug having the above configuration will be explained with reference to FIG. 14. The superconducting wires 3 supplied to the superconducting wire guide section 6 of the plug 4 through the eye plate 12 of the wire twisting machine are twisted together and moved to the superconducting wire aligning section 7, where each wire is arranged at a predetermined position. On the other hand, in conjunction with the supply of the superconducting wire 3, the reinforcing tape 13 is supplied through the reinforcing tape guide path 10 formed in the plug 4 .

This reinforcing tape 13 is inserted at the tip of the superconducting wire alignment section 7 and between the superconducting wires 3 arranged in the alignment section 7. The rear tip portion 11 is pressurized by rotating rolls 15 and 16 that are arranged close to the tip portion 11 of the superconducting wire alignment section 7 of the Turks head 14 to pinch the superconducting wire, and the tip portion 11 is further pressed. It is compression molded to its final state at a remote location. Reference numeral 17 denotes a main shaft of the wire twisting machine, and a reinforcing tape supply path 18 is provided on the central shaft.

As described above, in the present invention, since the reinforcing tape guide path is formed along the stranded wire axis from the base to the superconducting wire alignment section, the reinforcing tape can be easily inserted into the stranded superconducting wires. In addition, since a superconducting wire alignment section is provided at the tip of the superconducting wire guide section, the reinforcing tape supplied to the twisted superconducting wires is inserted in the final arrangement state, and the wires are sent to a rotating roll to continuously form a predetermined conductor. It can be manufactured as follows.
