BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for collecting an electric discharge machined wire in a wire electric discharge machine.

[0002]

2. Description of the Related Art With reference to FIG. 2, a conventional apparatus for collecting a wire subjected to electric discharge machining will be described. The wire 41 of a wire bobbin (not shown) held in the large-sized wire supply device 10 is a hard brass wire having a diameter of about 0.3 mm, and several guides arranged in place while being pulled by a pair of pinch rolls 11. The roller 12 guides the electric discharge machining unit 13 of the electric discharge machine 1 to perform electric discharge machining. The electric discharge machined wire 4 after the electric discharge machining is pulled by another pair of pinch rolls 14, and is collected by a plurality of guide rollers 15 arranged in a proper position, a collecting device 20 installed in the vicinity of the electric discharge machine 1.
While being continuously formed into a large loop shape or coil shape by the recovery device 20,
It is collected in the storage box 3.

[0003]

In the electric discharge machine 1 shown in FIG. 2, the wire bobbin of the wire supply device 10 is 15 to 20 kg.
Although it is of a large size and allows itself for a long time unmanned operation of the electric discharge machine 1, in the recovery device 20, the processed wire 4 is continuously formed into a large loop or coil shape. Therefore, the density of storage in the storage box 3 is low, and the processed wire 4 overflows from the storage box 3 in a short time, and the operation of the electric discharge machine 1 is stopped each time. And the storage box 3 must be taken out manually.
There was a problem that long-term continuous unmanned operation was not possible. The purpose of the present invention is to improve the storage density of the processed wires in the storage box and reduce the frequency of taking out the wire storage box, thereby enabling a longer continuous unmanned operation of the electric discharge machine. An object of the present invention is to provide a device for collecting an electric discharge machined wire.

[0004]

According to the first aspect of the present invention, there is provided a first apparatus for recovering a wire having been subjected to electric discharge machining, in order to attain the above-mentioned object, is provided with a wire extending along a direction in which the wire is discharged from the electric discharge machine. A cutter, a ring forming machine, and a wire storage box are continuously provided.

[0005] In the above-mentioned apparatus for recovering the electric discharge machined wire, a wire cutter is a rotary cutter, and a ring forming machine of the recovery apparatus is a hard roll and pressed against the hard roll, and the surface is made of an elastic material. It is preferable to employ a ring forming roll composed of a coated elastic roll.

Further, in the above-mentioned collecting apparatus, a wire cutter, a ring forming machine and a wire storage box may be installed along the traveling direction of the electric discharge machined wire fed from the electric discharge machine. Preferably, the wire cutter and the wire cutter are connected by a guide such as a guide roll, and the wire cutter and the ring forming machine are connected by a guide for guiding the cut wire from the wire cutter to the ring forming machine.

[0007]

In the electric wire machining apparatus according to the present invention, the electric discharge machine wire fed from the electric discharge machine is cut into a desired size by a wire cutter, and is then formed into a small ring or small loop by a ring forming machine. And the wire is stored in the storage box, so that the storage density of the wires in the storage box is much higher than that of the conventional device. In addition, since the cut electric discharge machined wire is a hard brass wire, there is a great risk of injury due to the cut end, but handling is more facilitated by being processed into a ring shape or a loop shape instead of a straight line. Be safe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIG. 1, a preferred embodiment of a device for recovering an electric discharge machined wire according to the present invention will be described.
FIG. 1 is a schematic sectional view showing an embodiment of a device for collecting a wire subjected to electrical discharge machining according to the present invention. The electric discharge machine 1 according to this embodiment has the same configuration as the conventional electric discharge machine shown in FIG.

In FIG. 1, an electric discharge machined wire 4 continuously fed from a wire electric discharge machine 1 is rotated by a guide comprising a pair of pinch rolls 9 and installed in a rotary cutter installed in a collecting device 2. The wire is guided to a wire cutter 5 constituted by the wire cutter 5, and is sequentially cut to a length of about 100 to 150 mm by the wire cutter 5.

[0010] The wire 8 cut into a short length as described above.
Is guided to the next ring forming machine 7 connected by the guide 6. The ring forming machine 7 of this embodiment includes a hard roll 70 made of a hard material such as a rope and an elastic roll pressed against the hard roll 70 and having a surface made of an elastic material such as urethane rubber. The hard roll 70 to be driven has the same diameter as the roll forming the wire cutter 5 and is rotated synchronously by the same motor M. Has become. And Guide 6
The short wire 6 guided between the rolls 70 and 71 by the rollers 60 and 71 is successively sandwiched between the two rolls 70 and 71, formed into a ring shape or a loop shape, and installed below. It is collected by falling under its own weight into the wire storage box 3.

According to the apparatus 2 for collecting a wire subjected to electric discharge machining in this embodiment, the wire is cut into a short length, formed into a ring shape or a loop shape, and collected in the storage box 3. 3, the frequency of manual removal is much lower than that of the conventional apparatus, so that the electric discharge machine can be operated unattended for a longer time. Further, since the wire cut into a short length is formed into a ring shape or a loop shape, the wire is less likely to be injured by the cut ends and can be handled more safely.

In the above-described embodiment, a rotary cutter is used as the wire cutter 5. However, if the processed wire 4 can be cut into a fixed size sequentially, other than the rotary cutter is used. Can be used.

[0013] The device for collecting a wire subjected to electric discharge machining according to the present invention is not limited to the above-described embodiment, but may add other elements or change non-main parts within the scope of the claims of the present invention. It includes the case of performing it.

[0014]

[Effects of the Invention] The electric wire machining apparatus according to the present invention sequentially cuts the electric discharge machined wires into short lengths.
Since this is formed into a ring shape or a loop shape and stored in the wire storage box, the wire storage density in the storage box is increased, and the frequency of manual removal work for wire recovery is reduced. Continuous automatic operation of the wire electric discharge machine for a longer time than before becomes possible. Further, since the wire used in the wire electric discharge machine is a hard material having a diameter of about 0.3 mm, it is dangerous to handle the wire simply by shortening the wire which has been subjected to the electric discharge machining. Since the processed wire is processed into a ring shape or a loop shape, safety can be ensured in handling such as taking out from the storage box.
