Abstract

PURPOSE:To make the storage of a discharging wire compact by providing a means of cutting a wire in an optional length with its synchronizing to a wire feeding speed. CONSTITUTION:The movement of a wire cutting blade (rotary blade) 4b is controlled by a control part 10 by detecting the wire presence at a wire guide part by a sensor 6 and the speed detection by a sensor 5 at a wire feeding driving part in order to cope with a wire feeding speed and an automatic connection, synchronized with the wire feeding as well and the cutting length is adjusted. The space saving storage of a wire 1 can thus be achieved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a wire processing device for discharging wire from a wire-cut electric discharge machine. The present invention relates to a wire-cut electric discharge machine and a discharge wire processing device that can be attached to any equipment structure and whether or not there is automatic wire connection.

[Conventional technology]

Conventional methods for discharging wire Q include discharging it into a storage bucket, winding it up, and waving the wire using a gear;
There is a method of discharging to the rear bucket, but the bucket becomes large because the wire is bulky.

In addition, in the single winding method in which it is difficult to dispose of the wire, it is necessary to synchronize with the wire feeding speed. In addition, the wire must be connected to the winding bobbin, and automatic wiring cannot be done unmanned.

[Problem to be solved by the invention]

The above conventional technology saves space in the storage bucket, makes it easier to dispose of wire, makes it easier to synchronize with the wire feed speed in the winding method, supports unmanned operation during automatic wire connection, and has limited equipment. There was a problem.

The object of the present invention is to enable easy installation, synchronization with wire feeding, and compact storage of discharge wires without requiring modification of the machine side or interface connection with NC control in existing equipment.

[0 Means to Solve the Problem] In order to achieve the above object, a storage bucket incorporating a wire guide and a wire cutting section is formed and can be attached to the wire discharge section. In order to cope with wire connection, the speed is detected by a sensor in the wire feed drive part, the presence or absence of wire is detected by a sensor in the wire guide part, the movement of the wire cutting blade is controlled and synchronized with the wire feed, and the cutting D is also adjustable in length. Space-saving storage of wires can be achieved by cutting the wires.

[Effect]

The wire feed speed detection unit detects the feed speed from the wire feed drive rotating section, and directly detects the feed speed that changes from time to time to control the operating speed of the wire cutting blade. The wire presence/absence detection sensor controls the cutting blade to move when there is a wire in the guide section, and to stop when there is no wire, and stops the cutting blade operation when there is no discharge wire during wire breakage or automatic wire connection. The wire cutting blade is controlled by the control unit to change its operating speed and stop its operation based on the detection by the sensor, and the wire is cut by a fixed blade and a rotary blade at the lower part of the guide.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 1 to 8. FIG. 1 is a cross-sectional view of the overall configuration of the discharge wire processing device according to the present invention as viewed from the front, FIG. 2 is a partially enlarged cross-sectional view of the side surface of the wire cutting section, and FIG. 8 is a bottom view of FIG. There is.

This device is composed of a guide part 2 for guiding the discharge wire l, a fixed blade 8, a rotary blade 4, a speed detection sensor 15, a wire detection sensor 6, and a storage bucket 7, which is attached to the wire discharge part 8. It is.

Said speed detection sensor? 5 is a wire detection sensor set in the wire feed drive rotating section. 6 is incorporated into the guide portion 2. The rotary blade 4 is rotated by a motor 9. The rotation of this motor 9 is controlled by calculating detection data from the speed sensor 5 and the wire detection center t6 by a control unit IO. Further, the fixed blade 8 has a structure that can be replaced depending on the diameter of the wire.

In this embodiment, insulators are used for the guide part 2, the fixed blade body 8a1 and the rotary blade body 4a, and the storage bucket 7,
The motor cover 11 is insulated with an insulating coating.

Further, in this embodiment, the speed detection sensor t5 and the wire detection sensor 6 can synchronize the wire feeding speed, automatic wire connection, etc. with one wire cut, and adjust the length of the wire one cut.

With the above configuration, since the wire 1 is cut, the storage capacity becomes compact.

〔Effect of the invention〕

According to the present invention, regardless of the V type of wire cap electrical discharge machine, it can be easily installed, and by cutting and discharging the discharging wire in synchronization with the feed speed, the discharging wire can be stored compactly, and the equipment layout can be made compact. space saving,
Wire disposal can be facilitated.
