Description

Ring-type rotary swivel manufacturing apparatus {Apparatus for forming ring swivel}

The present invention relates to an apparatus for manufacturing a ring-shaped revolver, and more particularly, to an apparatus for manufacturing a ring-shaped revolver that can be connected so that ropes, wires, chains, strings, etc. are not twisted.

In general, swivels used in various fishing gear are called by names such as swivels or swivels or swivel rings.

In particular, the revolving rod used for fishing gear is often formed in a larger size than the revolving ring used for accessories and smaller than the revolving ring used in construction, etc.

The revolver for fishing gear is used by connecting to a net, fishing net, or trap, and the revolver for accessories or construction tools is molded by casting using a mold, whereas the revolver for fishing gear is formed by bending the wire. .

In particular, revolvers for fishing gear are mainly used as a material of brass in the past because they are vulnerable to corrosion due to frequent contact with seawater, but recently they are being used as a material of stainless steel.

There are usually a single type, which forms a ring on only one side, and a double type, which forms a ring on both sides, and the ring and the ring are rotatably connected by a connecting pin.

The ring-type rotating aerodynamically has a structure in which a pair of rings are connected to each other rotatably by a connecting pin.

In other words, a pinhole 1a is formed in the ring-shaped first ring portion 1, and a pinhead 3a is formed at one end to prevent separation while the connection pin 3 penetrates the pinhole. And the second ring portion 2 is coupled to the other end of the connecting pin.

Accordingly, the first ring portion is coupled to the connecting pin in a rotatable state.

Conventionally, these first and second ring portions are welded between the ends of the wires by inserting the wires cut to a certain length into the bending device one by one and forming them into a desired shape one by one, and the first ring portion is punched, respectively. After allowing a pinhole to be formed by the

And the other end of the connecting pin is completed by welding the second ring portion and a welding device.

However, this process consumes a lot of manufacturing time and cost because the second loop part has to be separately made. That is, there was a disadvantage in that productivity is lowered.

In addition, since the connecting pin and the second ring are coupled by welding, if a large load is applied to the coupling part, it is easily deformed or the coupling part is damaged, thereby shortening the lifespan.

At this time, the first ring portion 1 is positioned on the lower side by gravity.

In addition, the first stopper 312 is positioned adjacent to the upper side of the end of the sliding rod 311 to temporarily stop the semi-finished product reaching the end of the sliding rod 311 . That is, the upper end of the second ring portion 2 is caught by the first stopper 312 and stops.

The first stopper 312 may have a plate member shape and is coupled to an end of the lever 313 on one side.

The lever 313 operates like a seesaw, and one end is hinged to be fixed, and the other end is coupled to the first stopper 312 . Accordingly, the first stopper 312 can be raised and lowered according to the forward and reverse rotation of the lever 313. When the first stopper 312 rises, the temporarily stopped semi-finished product is released and the sliding rod ( 311) and may fall.

In addition, the pressing member 314 is rotated by applying a force to the lever 313 , and as shown, one end is coupled to the second punch 223 of the bending unit 200 and interlocked.

And the other end of the pressing member 314 is bent upward to have a shape like 'b' as a whole.

Accordingly, when the second punch 223 rises, the pressing member 314 also rises, and when the upwardly bent end of the ascending pressing member 314 pushes up the lever 313, the lever 313 moves. The first stopper 312 rises while rotating. This may cause the semi-finished product to fall.

Next, the aligning means 320 rotates the semi-finished product falling from the sliding rod 311 by 180° around the first ring portion 1 so that the first ring portion 1 is positioned on the upper portion and the second portion is placed on the lower portion. As a configuration in which the two ring parts 2 are arranged to be positioned and then dropped again, a reverse cylinder 321 , a seating hopper 322 , a pushing member 323 , and an air sprayer 324 may be configured.

And, it is introduced between the upper rail 331a and the lower rail 331b and advances across the front of the first semi-finished product among the semi-finished products arranged in a line to stop the descent of all semi-finished products.

And the third stopper 333 is positioned between the first semi-finished product 11' and the second semi-finished product 12' and is lowered by a cylinder to separate the first semi-finished product and the second semi-finished product.

While the second stopper 332 and the third stopper 333 operate alternately, the semi-finished products may be supplied one by one. That is, when the third stopper 333 descends while the second stopper 332 stops all semi-finished products, and at the same time the second stopper 332 moves backward, the first semi-finished product moves downward and the welding part 400 ) is supplied.

However, other semi-finished products including the second semi-finished product are stopped by the third stopper 333 .

Then, when the second stopper 332 advances again and the third stopper 333 rises at the same time, the other semi-finished products including the second semi-finished product descend and are caught by the second stopper 332, thereby stopping the entirety.

In this way, the semi-finished products can be supplied one by one to the welding part 400 intermittently at regular time intervals.
