JPS6288516A - Wire-cut electric discharge machine and wire guide device - Google Patents

Abstract

PURPOSE:To permit the work for a workpiece having a complicate shape as an operator likes, by installing an apparatus which can bend a wire freely according to the shape of the workpiece between a working nozzle and a wire stop. CONSTITUTION:A curved arm 6 having the necessary form in accordance with the shape of a workpiece 5 is installed between a nozzle 2 installed onto a die block 1 and a wire stop 4 installed onto a water guide 3. A guide part 8 having a wire guide groove 7 is formed at the wire guiding position on the curved arm 6, and a wire 9 is engaged with the wire stop 4 through the guide part 8. With such constitution, only a part, such as the upper part of a workpiece can be worked as an operator likes, and even a workpiece having a complicate shape can be worked.

Description

[Detailed description of the invention] [Industrial application field] Wire electrical discharge machining.

[Conventional technology]

Even if a conventional wire electric discharge machine falls down, the workpiece is fixed by a wire stretched vertically between the machining nozzle 2 installed on the processing table of the wire electric discharge machine frame and the wire stopper 4 installed at the bottom. It was being processed.

[Problem that the invention seeks to solve]

Therefore, the upper and lower parts of the workpiece could only be machined into the same or similar shapes.

For example, in the case of a workpiece 5 as shown in FIG.
Even if you wanted to process only the parts, it was impossible or impossible, and the lower part 16 indicated by diagonal lines would be cut at the same time, making it impossible or extremely difficult to process objects with complex shapes as desired. .

[Means for solving problems]

Therefore, a device is provided between the machining nozzle of the wire electric discharge machine and the wire stopper to freely bend the wire according to the shape of the workpiece.

[Effect]

For example, the workpiece has a remarkable effect of being able to process only a part, such as the upper part, or even a complex-shaped object as desired.

〔Example〕

Further, to explain this with regard to an embodiment shown in the drawings, the shape of the workpiece 5 is formed between the nozzle 2 provided in the die block IK of the wire electrical discharge machine in question and the wire stopper 4 provided in the water guide 3. A guide portion 8 having a wire guide groove 7 is provided in the wire guide tube portion of the bent arm 6, and the wire 9 is secured to the wire through the guide portion 8. 4 is fixedly configured.

In the case of the Qin state where a wide variety of products with special shapes must be processed, a bending arm 6 is provided on the frame 10, and the bending arm 6 is
A wire guide device 11 is provided in which a guide portion 8 with a guide groove 7 is provided in each wire guide tube location, and the wire guide device 11 is detachably attached to the wire electrical discharge machine. It is extremely convenient and economical to replace the two.

It is convenient to provide a fitting hole 12 at one end of the frame 10 of the guide device 11 to fit into the wire stopper 4 of the wire electric discharge machine. Furthermore, the fitting hole 12 may be provided with a cutout 13 so that it can be fastened from both sides with bolts, nuts, etc.

Furthermore, each guide portion 8 may be a pulley type guide roller. What is the code 14 in the helmet? This shows the cytopore.

〔Effect of the invention〕

Since the present invention is structured like a savior, it has a very remarkable effect that even complex-shaped objects can be machined, such as only a part of the workpiece, such as the upper part, can be machined as desired.
