【発明の詳細な説明】 〔産業上の利用分野〕 本発明は鎖の製造方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing chains.
従来，この種の鎖の製造方法として本願の発明者は電気
スポット溶接機を利用した方法（特公昭５７−２６１７
６号公報参照）を発明した。Conventionally, as a manufacturing method for this type of chain, the inventor of the present application has proposed a method using an electric spot welding machine (Japanese Patent Publication No. 57-2617
(see Publication No. 6).
前記従来の技術において述べた電気スポット溶接機は各

って鎖を編上げるようにしたものである。In order to achieve the above object, the method for manufacturing the chain of the present invention involves clamping the front chain ring with a clamping device, winding the chain strands in a spiral shape with a screw rod, and then moving the front chain ring in the lateral direction in front of the clamping device. A movable device that operates in a horizontal direction, which is twisted horizontally from the holder and entwined with the front chain ring, and the terminal end of the coiled portion is placed in front of the clamping device and facing the same device. After positioning it between the blade and the fixed blade, the clamping part of the clamping device is released, the front chain ring hangs down to the one-turn part, and the clamping device is put into the clamping state again. At the same time, the movable blade is operated to separate the winding part from the chain element wire, and the clamping device is moved downward to remove the winding part from the receiving part provided below the movable blade. After this, both ends of the one turn are pressed against the receiving part by a crushing rod that operates from the horizontal direction toward the receiving part, and this is used as a rear chain ring, and the clamping device is raised. Then position both joints of the trailing chain in front of the torch of the plasma spot welding machine, which is placed above the movable blade and the fixed blade, and in this position, the trailing chain is welded by the plasma spot welding machine. Connect both ends of the joints to each other. Thereafter, the clamping device is returned to the initial position, the rear chain ring is placed in the initial position of the front chain ring, and the above steps are continued to braid the chain.
前記従来の技術において述べた電気スポット溶接機によ

めに各鎖環の両端接合部の周囲に隈（くま）ができてい
た。Since the electric spot welding operation using the electric spot welding machine described in the prior art is performed in the atmosphere (in oxygen), dark circles are formed around the joints at both ends of each chain ring.

。On the other hand, plasma spot welding using the plasma spot welding machine of the present invention is performed using an inert gas such as argon or helium ejected from the torch (L2).
Since it is made in a working gas), it is not oxidized and the finish is clean with no dark circles forming around the joints at both ends of each chain ring.

するものである。Since the present invention has the above-described structure, as described in the above-mentioned operation, there is a dark circle around the joints at both ends of each chain ring.
It has an excellent effect of completely achieving the intended purpose, and since it does not create dark circles as mentioned above, it makes it easier and more beautiful to perform surface treatments such as plating later. It is extremely convenient for finishing, and its effects are extremely great.Furthermore, since it can be welded without using a soldering iron, impurities will not enter the welded area, and in the case of pure gold (24K), it will not cause a decrease in value. It also has the following desirable effects.

) (see Fig. 1), the chain wire (3) is wound spirally with a screw rod (not shown), and the front of the clamping device [(2) Twist horizontally from the lateral direction to entangle a part (4) of the tip of the chain (3) with the front chain ring (1), and also twist the end of this part (4) of the chain. After positioning it between the movable blade (5) and the fixed blade (6) (see Figures 2 and 8), the clamping device (2) is released and the front chain ring (1) is removed. It hangs down on the winding part (4) (see Figure 3), and then, while moving the clamping device (2) forward, twist it 90 degrees and put it in the clamping state to pinch the winding part (4). (See Fig. 4) and operate the movable blade (5) to separate the first turn (4) from the chain element wire (3) (see Fig. 5). The same clamping device (
2) is moved downward to correspond to the receiving part (7) that is integrally provided below the movable blade (5), and then the one-turn part (4
) is pressed against the receiving part (7) by the pressing rod (9) which operates like the pressing rod (8).
(see figure), put the first winding part (4) into the rear chain ring OG, raise the clamping device (2), and weld both end joints αυ of the rear chain ring αO with a plasma spot welder ( At this position, both ends of the rear chain ring (IG) are connected to each other by a plasma spot welder (see the button in Figure 7 and the button in Figure 9). Then, while returning the clamping device (2) downward and moving it backwards, twist it 90 degrees in the opposite direction to the above, and then twist the clamping device (2) to the next turn Cl4.
The chain is knitted continuously by waiting for the entire entanglement step in step 1 and then continuing the above steps.
