Fig. 2 is a view schematically showing a state in which the stopper is formed by the casting-stopping-hole-forming apparatus of the wire according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, when a casting formed body is formed on an end portion of a wire, a stopper is formed at an end of the wire to prevent separation between the end of the wire and the casting formed body. And an apparatus for automatically performing a process of cutting a wire having a hook and a hook formed therein.

1 and 2, the apparatus for forming a casting jig for a wire according to the present invention includes a feeder 200, a mold unit 300, a mounting unit 400, a cutting unit 500, And a pressing unit (600).

The feeder 200 feeds each wire wound around the plurality of drums 100 to the mold unit 300. The feeder 200 is provided with a guide for guiding each wire in a predetermined direction, The feeding roller driven by the servo motor rotates and a wire is drawn between the feeding rollers to supply each wire to the mold unit 300. [

The mold unit 300 includes a mold member and a first cylinder member to which the plurality of wires supplied from the feeder 200 are passed and fixed, and each wire is passed through the mold unit.

The mold member is composed of a lower mold 310 and an upper mold 320. The lower mold 310 has a concave groove through which wires are respectively passed on the upper surface of the lower mold 310. The concave groove is smaller And can be formed with an inner diameter. The upper mold 320 may be disposed at an upper portion of the lower mold 310 and may have the same concave groove at a position corresponding to each of the concave grooves.

In addition, the rod of the rod is connected to each of both sides of the upper mold 320 to raise the upper mold 320, so that the feeder 100 is rotated, And the driving of the feeding roller is transmitted to the servomotor of the feeder 100. As the upper mold 320 is lowered, a signal is sent to the servomotor of the feeder 100 to stop driving the feeding roller, The supply of the wire is stopped and the positions of the respective wires can be fixed as they are assembled with the lower mold.

Next, the mounting unit 400 is installed at the front of the mold unit 300 and includes a mounting block 410 and a second cylinder member 420 in which wires passing through the mold unit are mounted as they are raised .

The stationary block 410 is disposed in front of the lower mold, and the wire passing through the mold member is fixed at its upper portion as the mold member is assembled.

The second cylinder member 420 is connected to the lower portion of the stationary block 410 to raise the stationary block 410 as the rod moves back and forth with the supply and discharge of the fluid. And the wire 410 is lowered to separate the wires and the mounting block 410 from each other.

The cutting unit 500 is installed on the upper portion of the mounting unit 400 and cuts each wire as it is lowered. The cutting unit 500 includes a cutter 510 and a third cylinder member 520.

The cutter 510 is disposed on the upper part of the stationary block 410, and the sharpened end of the cutter 510 is disposed in front of the stationary block 410.

In addition, the rod of the third cylinder member 520 is moved back and forth along with supply and discharge of the fluid, and the rod side is connected to the upper portion of the cutter 510 to lower the cutter 510 Each wire fixed to the front of the stationary block 410 is cut by the mold member and the stationary block 410 and the cutter 510 are separated from each other as the cutter 510 is raised.

The pressing unit 600 is installed opposite to the mold unit 300 and presses the ends of each of the cut wires as it advances to form a stop. The punch 610, the moving block 620, 4 cylinder member 640 as shown in FIG.

The punches 610 are arranged in a plurality of positions, each of which is disposed opposite to the mold member and has a groove for forming a stopper at an end thereof. More precisely, each of the stopper- Respectively.

In addition, the moving block 620 is installed such that each of the punches 610 is fixed to the end thereof and is movable back and forth along the LM guide 630 disposed at the lower side.

Further, as the rod side is connected to the moving block 620 to move the moving block 620 forward, the rod side of the fourth cylinder member 640 is moved in the direction And the punch 610 is pressed to each wire end portion cut by the cutting unit 500 to enable the formation of the hooks at the respective wire end portions by the stopper forming grooves, So that the mold member and the respective punches 610 are separated from each other.

Hereinafter, a description will be made of the operation of the casting forming jig forming device of the wire according to the present invention.

When each of the wires supplied by the feeder 200 passes through the mold member, the lower mold 310 and the upper mold 320 are combined and the supply of the wire is stopped. When the stationary block 410 is lifted and the wire on the front side of the mold member is mounted, the cutter 510 is lowered to cut the wire so that the length of the wire stuck to the stationary block 410 can be preserved. Then, when the cutter 510 is lifted and the stationary block 410 is lowered, the punch 610 presses the wire as much as the length of the punch 610 to form a hook at the end of the cut wire. Lt; / RTI >

As described above, the technical idea of the present invention is to supply the wire, cut the wire, form the stopper of the end of the wire, and cut the wire with the stopper to automatically form the stopper of the end of the wire, It is understood that the present invention is to provide a casting forming jig forming device for a wire which can be automatically carried out.

It will be apparent to those skilled in the art that various modifications, substitutions, and alterations can be made hereto without departing from the spirit and scope of the present invention as defined by the appended claims. It will be possible.
