Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for removing metal filler by a shaving tool from a metal wire consisting of two or more types of metals such as iron, aluminum, copper, titanium, etc. and alloys thereof, where L< is two or more types. The present invention relates to a method of manufacturing a metal material by cutting and twisting a plurality of metal fillers.

BACKGROUND OF THE INVENTION Conventionally, various methods are known for producing metal-based materials. For example, as shown in FIG. 4, a metal wire 41 having a circular cross-sectional shape is wound around two cap stans 42 and 43 facing each other multiple times from a Zaburi drum 46 and run under tension while being wired with tool steel, ultraviolet steel, etc. Shaving bit made of hard or ceramic material and having serration grooves 44. ..., 44 is the metal wire 4
1 and cut it, the metal filler 45
A method for producing steel wool is known, and this method is used to produce steel wool, etc.
Publication No. 30). In addition, in the figure, 47 is a winding drum for winding up the metal filler 45, and 48 is a winding drum for winding up the remaining metal wire 41 from which the metal filler 45 has been removed.

Problems to be Solved by the Invention However, with the metal filler produced by the above method, fine curls are formed on the outer surface mainly during cutting, and these curls tend to entangle the metal fillers with each other. After winding it up, if you try to unwind it to continuously cut out the appropriate amount of metal, the metals will become intertwined with each other, making it impossible to unwind the metal smoothly. Since the metal material itself is extremely thin and has low strength, the metal material may break, and it is extremely difficult to rewind the metal material by an appropriate amount. In addition, it is possible to line up and store it in a container without winding it up into a spool, but since the bulk specific gravity is small, the tare becomes large, which is not desirable for transportation, and it is impossible to avoid entanglement with metal objects. , it is difficult to continuously cut out an appropriate amount.

Continuously cutting out appropriate amounts of metal in this way is similar to the process of spinning natural fibers, in which fibers are tempered by carding and drawing and then processed into spinning and twisting processes to form yarn. This is extremely important in terms of quality and production in the yarn twisting process.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide a method for producing a metal material that can continuously unwind an appropriate amount of the metal material from a winding bobbin or the like. There is a particular thing.

Means for Solving the Problems In order to achieve the above object, the present invention presses a shaving tool against a metal wire to shave off the metal filler,
A plurality of shaved metal fillers were twisted together and then wound into a winding bobbin as a twisted yarn. That is, a shaving tool is brought into contact with a metal wire tensioned between a pair of capstans, a metal filler is removed from the metal wire with the shaving tool, and a plurality of removed metal fillers are twisted together to form a twisted yarn; The twisted yarn was configured to be wound around a metal winding bobbin.

In the above structure, the metal filler is shaved off from the metal wire with a shaving tool, and then a plurality of these metal fillers are twisted together to form a twisted yarn to improve the strength of the metal system. By winding the system onto a winding bobbin or the like, even if the metal system is entangled, it is possible to continuously unwind an appropriate amount of the metal system from the winding bobbin or the like.

Thereafter, the twisted yarn 35 is wound onto each winding bobbin 12. Also, in each metal filler manufacturing machine 1.2, the remaining metal wire 8 is wound around one capstan 4, and then the metal wire winding device 6 Wind it up.

Here, when manufacturing the above metal system, the unit weight per length of the metal system, the shape, and the composition ratio in the case of a dissimilar metal system are as follows:
It can be freely determined mainly based on the following items or an appropriate combination thereof.

That is, ■ the number of metal wires 7 to be wound on the bobbin mounted on the metal filler manufacturing machine 1.2, ■ the number of shaving bits 9 to shave the metal wires 7 to be bundled together, and ■ the metal filler manufacturing machine 1. , 2, ■ the relative stress between the shaving bit 9 and the metal wire 7, and ■ the cutting speed, that is, the traveling speed of the metal wire 7, and the metal filler 14. It is determined from the running speed ratio of the metal filler 14 set by a group of guide rollers that guide the yarn to the twisting device 11. Among these, the operating speed ratio (■) above is such that the metal filler 14 can be stably shaved by the cutting tool 9.
This is most important in guiding the yarn from the metal filler 14 to the twisting device, and depending on the shape, strength, curl condition, etc. of the metal filler 14,
It is necessary to select the ratio of the traveling speed (travel speed of metal filler/metal wire) within the range of 1.1 to 3.5.

According to the above embodiment, the metal filler 14 cut from the metal wire 7 is 1. A plurality of threads are combined into a twisting device 11
The yarn is guided until the yarn is twisted by the yarn twisting device 11, and the yarn is twisted into yarn 3.
After forming the thread 5, the twisted yarn 35 is wound onto the winding bobbin I2, so that the strength of the metal 35 which is twisted together with the metal filler 14 and wound onto the winding bobbin 12 is improved. When rewinding, a little metal 35
By forcibly rewinding when comrades are entangled,
An appropriate amount of the metal 35 can be rewound from the winding drum 12 without cutting the metal 35. In addition, since the shaving bits 9 are arranged in multiples of 3 so that the metal fillers 14 are shaved simultaneously in multiples of 3, by twisting these metal fillers I4 together, one thread or multiple threads of three threads can be simultaneously removed. The metal type 35, 35.35 can be manufactured, and the manufacturing efficiency is good. Moreover, if the metal filler 14 is cut from different metal wires 7 in the first metal filler manufacturing machine 1 and the second metal filler manufacturing machine 2, and the metal fillers 14 and 14 of different metals are twisted together, one Alternatively, a large number of composite metal strips can be manufactured simultaneously.

Note that the present invention is not limited to the above embodiments,
It can be implemented in various other ways. For example, in the above embodiment, four metal fillers 14. ..., 14 are twisted together to form the twisted yarn 35, but depending on the application, an arbitrary number of metal fillers 14, ..., 14 of two or more may be twisted together to form the twisted yarn 35. You can also do this. Further, the yarn twisting device 11 is not limited to the structure described above, but may be of a known structure as shown in FIG. 3 (see Japanese Patent Laid-Open No. 48-6028). That is, a plurality of combined metal fillers 14 are gathered into a collective voice 27 by the guidance of a guide roller 26, and this assembled sterand is passed through a straightening roller 28 and inserted into a tubular 29, and then a motor 30, a pulley 31, a belt 32 The twisted yarn 35 is twisted by the tubular 29 which rotates in the twisting direction.
After forming, the take-up drum 33 and the traverse 3

Effects of the Invention According to the above configuration, a plurality of metal fillers cut from a metal wire are combined, twisted together by a twisting device to form a twisted yarn, and then the twisted yarn is wound onto a winding bobbin. Metals made of multiple strands are stronger than conventional metals made of a single metal filler, so when unwinding metals, even if the metals are slightly intertwined, it will be forced to unwind. As a result, an appropriate amount of metal can be rewound from the winding drum without cutting the metal. Further, by twisting together different metal fillers cut from different metals, a composite metal system with one or multiple threads can be easily manufactured.
