Problems solved by technology

Therefore, in the traditionally manual work of knotting steel wires together, the flexural rigidity increases due to the increased diameter of the wires, leading to an increase in the work load.
In addition, since the diameter of the nodules of the wire tends to become larger, the space of the diameter of the guide hole through which the wire of the twister passes becomes not large enough, whereby it is difficult for the nodules to pass through the hole, which creates a problem

Embodiment

[0060] Hereinafter, the manufacturing method and manufacturing apparatus of the present invention will be described in detail with reference to examples.

[0061]

[0062] by using figure 1 A wire body connecting device of the type shown connects steel wires with a diameter of 0.45mm. The wire body holding member of the fixing member had an angle of 1.5° with respect to the depth direction of the notch portion, and a width of 0.46 mm. A guide with a width of 13 mm and an angle of 30° for guiding the steel wire was provided on the fixing member. The pressing force applied by the pressing member to the steel bar was set at 65N. The leaf spring has a length of 27mm, a width of 22mm and a thickness of 0.7mm. The time required to connect metal wire rods by using the connection device and the thickness of the nodule were measured. The results are listed in Table 1.

Abstract

Provided is a metal filament body connecting method that achieves easy connection work and a metal filament body connecting device that is lightweight and has excellent portability. A metal filament body connecting device is used for connecting opposite metal filament bodies (20) to each other. A pair of securing parts (1) for securing the opposite metal filament bodies (20), and a rotation body (2) provided with a notch (2A) between the pair of securing parts (1) at an appropriate distance therefrom are provided, both ends of metal filament body parallel parts (20A) formed by disposing the opposite metal filament bodies (20) side by side are secured by the pair of securing parts (1), approximately central sections of the metal filament body parallel parts (20A) are disposed in the notch (2A) of the rotation body (2), and thereafter the opposite metal filament bodies (20); are twisted by rotating the rotation body (2). The pair of securing parts (1) are respectively provided with notches (1A) and pressing members (1B), both the ends of the metal filament body parallel parts (20A) are disposed in the notches (1A), respectively, and secured by pressing both the ends by the pressing members (1B).

Description

technical field [0001] The present invention relates to a method for connecting metal wire bodies (hereinafter also referred to simply as "connecting method") and a connecting device (hereinafter also referred to simply as "connecting device"), and more particularly relates to a metal wire body which is easy to connect. body connection method and metal wire body connection device with light weight and excellent portability. Background technique [0002] A steel cord used to reinforce rubber articles such as tires is manufactured by twisting together a plurality of steel wire strands by a twisting machine. Examples of steel cord twisting machines include tubular type twisting machines and twisting type twisting machines; when steel cords are manufactured, work of changing steel rod materials is unavoidable. Therefore, the work of knotting the steel wire remaining on the twister and the newly replaced steel wire as material is carried out. [0003] In recent years, in order ...
