Abstract

PURPOSE:To fix a rapidly cooled metal on a rotating cylindrical body and to wind the metal without breaking by bending the top part of the metal introduced into the cylindrical body from an opening part on the inner peripheral surface of the body by a bar semifixedly installed in the body. CONSTITUTION:The top part of a rapidly cooled metal 1 is introduced into the inside of a cylindrical body 5 with the body 5 rotated at a speed equal to the casting speed of the metal 1. A bar 7 installed on the inner surface of the body 5 bends the top part of the metal 1 to wind the metal 1 on a cylindrical body 2 in that situation. The winding is efficiently performed by a device of that structure.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a winding device for quenched cast metal, and relates to a quenched metal ribbon made of a material with high mechanical strength, low elastic strain limit, and easy bending deformation. This relates to a winding device for threading multi-thread ribbons, multi-thread wires, etc.

[Conventional technology]

Conventionally, many methods have been proposed for winding rapidly cooled cast metal. For example, the present inventor previously proposed a method in which a dummy sheet is wrapped around a magnetic roll and a rapidly cooled metal is sandwiched therebetween to start winding. Also, JP-A-55-704
No. 14 and Japanese Unexamined Patent Publication No. 57-94453 propose a method of directly winding quenched metal onto a magnetic roll.

However, the method of using a dummy sheet has high mechanical strength, low elastic strain limit, and rapidly quenched metal that is easily bent and deformed. Therefore, it is difficult to reliably capture rapidly cooled metal of the above-mentioned material running at high speed using conventional winding methods.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION In order to solve the problems of the conventional method, the present invention provides a winding device for rapidly solidified metal that has high mechanical strength, a low elastic strain limit, and is suitable for rapidly solidified metal that is easily bent and deformed.

[Means for solving problems]

The present invention provides a rotating cylindrical body having a plurality of openings on its circumferential surface;
a quenching metal winding device comprising a strip disposed close to the inner peripheral surface of the rotating cylinder in a direction perpendicular to the rotation axis of the rotating cylinder, and a plurality of strips arranged in a direction parallel to the rotation axis. A rotating body configured such that these strips form a circumferential surface during rotation; This is a quenching metal winding device consisting of arranged strips.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of the outer surface of the entire device according to one example of the present invention, and FIG. 2 is a side cross-sectional view of the section AB shown in FIG. 1.

In this example, the winding device 2 includes a rotating cylindrical body 5 having a plurality of openings 4 on the circumferential surface 3, and a rotary cylindrical body 5 having a plurality of openings 4 disposed inside the rotating cylindrical body 5 in parallel with the rotation axis 6 of the rotary body. It is characterized by being composed of strips 7 provided in the direction.

The strip 7 is fixed to the pipe 9 by a support 8.

The pipe 9 has an inner diameter larger than that of the rotating shaft 6 and is fitted into the rotating shaft, and a weight 10 is attached below the pipe 9. Therefore, even if the rotating shaft 6 rotates, the strip 7 can be placed at a preset position.

Next, a method for winding quenched metal using this device will be explained.

When the quenched metal 1 is guided to the winding device 2 by a known method while rotating the rotating cylindrical body 5 at a circumferential speed equal to the casting speed of the quenched metal, the tip of the quenched metal passes through the opening 4 of the rotating cylindrical body 5
A strip 7 that penetrates into the inside of the cylinder and moves in the rotational direction as the cylinder rotates, but is placed close to the inner peripheral surface of the cylinder.
As a result, the tip thereof is bent as shown by the broken line in FIG.

In this manner, the rapidly cooled metal rotates at high speed with the rotating cylinder with its tip end bent, and winding is started.

Next, another example of the present invention will be described.

FIG. 3 is a perspective view of the outer surface of the entire device according to another example of the present invention.
Moreover, FIG. 4 shows a side cross section of the -D section shown in FIG. 3.

In this example, the winding device 2 moves a plurality of strips 13 onto its rotating shaft 6.
A rotating body 12 is arranged in a direction parallel to the rotating body so that the strip forms a circumferential surface during rotation; It is characterized in that it is composed of another strip 14 arranged in a direction parallel to the axis.

The strip 14 disposed inside the rotary body 12 is fixed to the pipe 9 by the support member 8 as in the case of FIG. , and a weight 10 is attached below it. Therefore, even if the rotating shaft 6 rotates, the strip 14 can be placed at a preset position.

Next, a method for winding quenched metal using this device will be explained.

When the quenched metal 1 is guided to the winding device 2 by a known method while rotating the rotating body 12 at a circumferential speed equal to the casting speed of the quenched metal, the tip of the quenched metal is inserted between the strips 15 of the rotating body 12. The strip 14 inserted inside the rotating body 12 moves in the rotational direction as the rotating body 12 rotates.
As a result, its tip is bent as shown by the broken line in FIG.

In this way, the quenched metal starts to be wound up by rotating at high speed with the rotating body while the tip thereof is bent.

〔Effect of the invention〕

When using the apparatus of the present invention, even if the shape of the quenched metal is poor, and regardless of whether or not the quenched metal has magnetism, it is possible to easily start inserting and winding.

Therefore, it can be easily applied to rapidly solidified metals that have high mechanical strength, low elastic strain limits, and are easily bent and deformed.
