Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sludge removal device that separates and removes sludge generated during electrical discharge machining in a wire-cut electrical discharge machine.

[Conventional technology]

Generally, in a wire-cut electrical discharge machine, when wire-cut electrical discharge is performed, relatively large particles of sludge from melt processing and relatively small particles of sludge from ion processing are mixed into the machining fluid.
A conventional sludge removal device for removing sludge mixed with relatively large particles removes sludge by supplying machining fluid from a machining tank to a machining fluid tank and then passing it through a paper filter. Therefore, since the conventional sludge removal apparatus removes sludge using only the paper filter, there is a problem that the filter has a short life span, requires frequent replacement work, and has poor maintenance effectiveness. Also,
Paper filters have the problem of high maintenance costs because they are disposable.

[The problem that the idea aims to solve]

In order to improve the above-mentioned problems, it is conceivable to remove relatively large sludge by filtration, and then supply processing liquid containing relatively small sludge to a settling tank to remove the sludge. However, the wire cutting machine does not have enough space to install a large device, and there are also problems in processing precipitated sludge.

The present invention improves the above-mentioned problems and separates and removes sludge with large particles even with a relatively small device, and allows sufficient settling time for sludge with small particles to reliably remove the sludge. It is an object of the present invention to provide a sludge removal device for a wire-cut electrical discharge machine, which is capable of cleaning the sludge easily.

[Means to solve the problem]

In order to improve the above-mentioned problems, the present invention
It consists of a box-shaped sedimentation tank and an outer box that removably supports the sedimentation tank.A take-out lever is fixed to the upper part of the sediment tank, and a comparative plate is supported by a perforated plate below the take-out lever. A sludge removal sheet made of large particles is arranged, and the inside of the settling tank below the perforated plate is partitioned into a plurality of tanks by a plurality of vertical partition plates, and notches are provided alternately at the upper end of each partition plate. Adjacent tanks are connected by the section to form a meandering flow path by each tank and the notch, and when the sedimentation tank is installed in the outer box, the drain pipe is located at the upper part of the first tank of the sedimentation tanks. It is characterized by being configured to do so.

[Effect]

Since the sludge removal device of the present invention has the above-described configuration, the processing fluid supplied from the drain pipe passes through the sheet to remove sludge consisting of relatively large particles, and then settles below the sludge. When the liquid level in the first tank reaches the upper end of the partition plate, the processing liquid flows into the second tank through the notch, and thus the processing liquid flows into the settling tank. Since the sludge is discharged from the discharge hole in a meandering manner one after another, it is possible to take a sufficiently long settling time even in a relatively small settling tank, thereby making it possible to reliably remove the sludge in the machining fluid. Further, after capturing the sludge in the sheet and the settling tank, the inside can be easily cleaned by removing the settling tank from the outer box by holding the take-out lever.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the sludge removal device according to the present invention will be described in detail below with reference to the drawings. Fig. 1 is a conceptual diagram for explaining the relationship between the sludge removal device and the wire cut electrical discharge machine according to the present invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Fig. 3 is a cross-sectional view taken along line B-- in Fig. 2. It is a sectional view of B.

In FIG. 1, 1 is the main body of the wire cut processing machine, 2 is a processing tank, and 3 is a drain pipe that supplies the processing liquid discharged from the processing tank 2 to the sludge removal device 4.
The machining fluid containing sludge generated in the machining tank 2 by the machining machine main body 1 is supplied to the sludge removal device 4 through the drain pipe 3, and after the sludge is removed, it is transferred to the machining fluid tank (not shown). Configured to be collected.

As shown in FIGS. 2 and 3, the sludge removal device according to the present invention is composed of a box-shaped settling tank 6 and an outer box 4a that detachably supports the settling tank. When attached to the outer box 4a, the settling tank 6 is positioned by the stop plate 5.

The sedimentation tank 6 has a take-out lever 12 fixed to its upper part, and a perforated plate 10 fixed slightly below it, and a sheet, such as a sponge, for removing sludge consisting of relatively large particles by the perforated plate 10. It supports the sheet 11. In addition, the perforated plate 10
The lower part is divided into a plurality of tanks A, B, C, and D by a plurality of vertical partition plates 7, and notches 8a, 8b, and 8c are provided alternately at the upper end of each vertical partition plate 7, and the final stage tank is divided into a plurality of tanks A, B, C, and D. A discharge hole 9 is provided in the upper part of the wall of D.

Further, as described above, the outer box 4a is equipped with a stop plate 5 for positioning the settling tank 6, and a drain pipe 14 for supplying the processing liquid to the processing liquid tank (not shown) discharged from the sludge removal device. There is. And outer box 4
When the settling tank 6 is attached to the tank A, the drain pipe 3 for the processing fluid discharged from the processing tank 2 is positioned by the stop plate 5 so that it is located directly above the first tank A, as shown in FIG. . Note that 13 is a bolt for attaching the sludge removing device of the present invention to the machine body 1.

Since the sludge removal device of the present invention is constructed as described above, the processing fluid supplied from the drain pipe 3 first passes through the sponge sheet 11 to remove sludge consisting of relatively large particles. The liquid flows into the first tank A of the settling tank 6, and when the liquid level in the first tank A rises and reaches the notch 8a, the third tank
As shown in the figure, the machining fluid flows into the second tank B, and thus the machining fluid flows in a meandering manner from the first tank A to the fourth tank D (in the case of the illustrated embodiment). After allowing sufficient time for the sludge to settle, the sludge consisting of relatively small particles is sedimented and removed, and then flows into the outer box 4a and is supplied to the external machining liquid tank via the drain pipe 14. Furthermore, the sludge captured by the sponge sheet 11 and the settling tank can be easily cleaned by holding the take-out lever 12 and removing the settling tank 6 from the outer box 4a.

[Effect of idea]

As described above, according to the present invention, even with a relatively small device, large particle sludge can be removed by the sheet, and the settling time of the particle sludge is sufficiently long to ensure the removal of sludge in the machining fluid. Furthermore, after capturing the sludge, the settling tank can be removed and cleaned easily.
