[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying a long hard brazing material to a brazing point.

[0002]

2. Description of the Related Art Solder materials include soft solder having a low melting temperature and hard solder having a high melting temperature. Soft solder is Pb, Sn, Z
n, Cd, etc. are used as the main components. In order to braze these brazing materials, a soldering iron, a reflow furnace, and a solder bath are used. If the material to be brazed is large, use a flame device such as an oxygen-acetylene flame or an oxygen-hydrogen flame.

On the other hand, hard solder is mainly composed of Ag, Cu, Ni or the like. To braze these brazing materials, a flame device or a high-frequency heating device is used. Is often used.

[0004] When using a fire device with soft or hard solder, an operator holds a bar of a certain length in one hand and a flame device in the other hand to cover the end of the bar. While applying to the brazing part, it was heated by a flame device to perform brazing.

[0005] In the brazing using this flame device, the rod-shaped brazing material can be used to a length that can be held by hand, but the shorter brazing material is discarded, or the shorter brazing material is replaced with pliers. It was used by switching to a brazing part. However, even the brazing material that was replaced with pliers could not be used up to the portion sandwiched between the pliers, and that portion was discarded.

[0006] In other words, not only is there an economical loss that all of the rod-shaped brazing material cannot be used for brazing, but also there is a problem in that the shortened brazing material must be replaced with pliers.
However, almost all long brazing materials can be used.
And there is no need to change them with pliers .

The brazing filler metal of the long Disclosed devised to solve the above-or wound bobbin, or unwinding from spool in a cylindrical vessel at the use and added in coiled <br/>, cylinder It was feeding from Jo container
Interest and are using. By the way, in general, soft solder containing Pb or Sn as a main component is soft and easy to supply even into a long material, but soft solder containing Zn or Cd as a main component is very hard and made into a long material. It is difficult to supply. Also
Hard brazing is also very hard ones either, soft solder of Zn, difficult to supply a Cd main component similarly long material.

In other words, a long hard brazing material wound around a winding frame or put into a cylindrical container in a coiled form, when unwound from the winding frame or when unwound from the cylindrical container, forms a large loop of a rolled shape. As supplied, the operator had to braze while straightening it by hand. Therefore, this brazing material was accompanied by a very laborious work of straightening work in addition to the brazing work.

[0010] In addition, a long brazing filler metal remains long just by taking it out of a bobbin or a cylindrical container, and it is inconvenient to handle it because it has no fixed direction when working with it. Was.

[0011] The present invention provides a long brazing material in which a hard and long brazing material is supplied in a straightened shape and a brazing material with a length that is easy for an operator to use is provided, and furthermore, handling is convenient. An object of the present invention is to provide a material supply device.

[0012]

Means for Solving the Problems The present inventors need to straighten a long hard brazing material wound on a bobbin or put in a cylindrical container at the same time as straightening and supplying it to a worker's hand. The present invention was completed by noting that it was convenient and easy to handle.

According to the present invention, there is provided a body having a plurality of straightening rollers and a feed roller, a mounting table on which a long brazing material can be placed, an arm rotatably installed, and a long arm installed at an end of the arm. A supply device for a long brazing material, comprising a holder capable of holding a long brazing material.

The present invention will be described below with reference to the drawings.
FIG. 1 is a front view of the long brazing material supply device of the present invention.

The feeding device for a long brazing material according to the present invention comprises:
It is composed of a soldering table 2, an arm 3, and a holder 4. A guide bush 5 is provided at a lower end of the main body 1, and a plurality of correction rollers 6 are provided diagonally above the guide bush 5. Two straightening rollers are provided in the upper part and one in the lower part in the middle.

A guide roller 7 is installed diagonally above the correction rollers 6..., And a pair of feed rollers 8 are installed diagonally above the correction rollers 6. One of the feed rollers is driven by a motor mounted on the back side of the main body. If at least one of the pair of feed rollers is provided with a gear shape or a knurl, it can bite into the long brazing material and completely feed the long brazing material.

A guide bush 9 is installed diagonally above the feed rollers 8, 8, and a guide roller 10 is installed diagonally above the feed bush 9. A guide bush 11 is disposed diagonally below the guide roller 10, a pair of feed rollers 12, 12 are disposed diagonally below the guide bush 11, a guide roller 13 is disposed diagonally below the guide bush 11, and three correction rollers 14 are disposed diagonally below the guide bush 11.

The brazing material placing table 2 is adapted to rotatably place a winding frame 15 around which a long brazing material S is wound as shown in the figure.
The soldering table may be such that the reel can be set aside or a cylindrical container containing a long brazing filler metal can be placed.
In each case, the brazing material mount comes out without the long brazing material getting tangled.

A balancer 16 is attached to one end of the arm 3, and a slightly lower portion thereof is rotatably mounted on the main body 1 via a rotating piece 17. Therefore, the arm 3 is the rotating piece 1
7, it has a degree of freedom such that it can rotate as shown by the arrow A and move up and down as shown by the arrow B. The weight of the arm 3 is balanced by the balancer 16 so that the arm 3 can be easily operated with the holder 4 installed at the other end. A guide piece 18 for guiding the long brazing material coming out of the main body to the holder is provided at substantially the center of the arm 3.

The holder 4 comprises a grip 19, a guide pipe 20, and a switch 21, and the grip 19 is formed in a columnar shape that is easy for an operator to grip and is installed at right angles to the arm 3.
