Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a wire-cut electric discharge machine, and more particularly, to a wire-cut electric discharge machine equipped with a wire recovery device for recovering used wire.

[Technical background of the invention and its problems]

In wire-cut electrical discharge machines, the used wire that has been electrically discharged is generally wound around a take-up reel and disposed of, or it is drained into a wire collection box, and when the collection box is filled with wire, it is taken out from the collection box and disposed of. The structure is in place.

However, in the case of such a wire collection device, there are problems such as the configuration is complicated due to the installation of the take-up reel, and it takes time to dispose of the wire because the wire is taken out by hand from the collection box. Ta.

[Purpose of invention]

This idea was made in view of the conventional problems mentioned above, and it is easy to collect used wires, can be collected by wire material, and can be collected without getting in the way when the wire is not in use. It is an object of the present invention to provide a wire cut electric discharge machine equipped with a device.

[Structure of the idea]

This idea is a wire-cut electrical discharge machine equipped with a wire collection device for collecting used wire in wire-cut electrical discharge machining. A locking arm provided on the holder is provided so as to be freely changeable between a horizontal state supporting a collection bag for collecting wires and a folded hanging state, and a hook for supporting a spare collection bag is provided on a part of the locking arm. It is made up of the following.

[Example of idea]

FIG. 1 shows the entire wire-cut electric discharge machine, in which a wire 5 fed out from a wire feed reel 3 passes through a tension roller 7, reaches a nozzle 9, and is placed on a work table 11. Wire cut electrical discharge machining is performed on the wire W. The used wire after this electric discharge machining is passed through the nozzle 13 and then passed through the winding roller 1.
5 and are continuously discarded.

A wire collection device 17 and a collection bag receiving plate 19 are foldably attached to the side surface of the processing machine main body 1. A guide member 23 for guiding the used wire 5 to the collection bag 21 of the wire collection device 17 is provided on the side of the winding roller 15.

The detailed structure of the wire collection device 17 and the collection bag receiving plate 19 is shown in FIGS. 2 to 4. The wire recovery device 17 is horizontally supported on the side of the processing machine main body 1 by a mounting bracket 25, and includes a locking arm 27 that is foldably supported in a suspended state, and a support arm that supports this locking arm 27 in a horizontal state. 29
It is equipped with A hook 31 is attached to the tip of the locking arm 27. A collection bag 21 made of vinyl or paper is locked to the locking arm 27 in an open state. Further, an appropriate number of spare bags 33 are secured to the hook 31 in a folded state.

The collection bag receiving plate 19 is supported horizontally by a support arm 35, and a magnet 37 for suction is attached to the tip.

The operation of the wire recovery device having the above configuration will be explained next. As shown in FIG. 1, the wire 5 that has become used due to the wire cut electrical discharge machining is continuously sent out toward the guide member 23 by the winding roller 15. The used wire 5 then passes through the guide member 23 into the collection bag 21 of the locking arm 27.
It is guided within and stored here.

As shown in FIGS. 2 and 3, when the collection bag 21 is full, the collection bag is removed and placed on the collection bag receiving plate 19, and a new one is added from the spare bag 33.
The sheet is taken out and attached to the locking arm 27. In this way, when the collection bag 21 becomes full, it is replaced with a spare bag 33 one after another, and the used wire 5 is collected into the bag.

When not in use, the support arms 29, 35 are removed, and the locking arm 27 and collection bag receiving plate 19 are folded, respectively, as shown in FIG. At this time, since the collection bag receiving plate 19 is provided with a magnet 37, the upper end thereof is held in a vertical state with its upper end attracted to the processing machine main body 1, as shown in FIG.

[Effect of idea]

As can be understood from the above description of the embodiments, the present invention basically consists of a wire recovery device 1 for recovering wire 5 used in wire cut electrical discharge machining.
A wire cut electrical discharge machine equipped with 7
A locking arm 27 provided on the side surface of the processing machine main body 1 corresponding to a guide member 23 that guides the used wire 5 to the wire collection device 17 is placed in a horizontal state that supports a collection bag 21 for collecting the wire 5. A hook 31 for supporting a spare collection bag 33 is provided on a portion of the locking arm 27, which can be changed to a folded and suspended state.

As is clear from the above configuration, in the present invention, the locking arm 27 that supports the collection bag 21 for collecting the used wire 5 in the wire cut electrical discharge machine is foldable from a horizontal state to a suspended state. In addition, one part is provided with a hook 31 for supporting a spare collection bag 33.

Therefore, according to the present invention, the used wires 5 can be easily collected, and by attaching and detaching the collection bag to the locking arm 29, it is possible to collect the wires by material. Furthermore, when the vehicle is at rest, the locking arm 27 is folded into a suspended state, so that it does not become a hindrance.
