Description

[Detailed Description of the Invention] The present invention relates to a machining tank in an electrical discharge machine.

Conventionally, the machining tank 1 in an electric discharge machine is shown in Figs. 1 and 2.
As shown in the figure, the electric discharge machining fluid is fixed on the table 2 through a backing 3 with bolts 4, and the electrical discharge machining fluid is supplied to the table 2 via a machining fluid control device 5 attached to the side of the machining tank 1 through a valve 6 and piping 7. and those fed through the elbow 8 are implemented.

However, in the above configuration, the machining fluid from the elbow 8 does not flow all over the interior of the machining tank 1, and only a portion of the machining fluid does not flow, which causes a decrease in electrical discharge machining efficiency.

The present invention eliminates the above-mentioned drawbacks, and allows the machining fluid to flow throughout the entire machining tank and be discharged.This allows electrical discharge machining to be performed with always clean machining fluid, enabling highly efficient electrical discharge machining. Our purpose is to provide processing tanks for machines.

In order to achieve the above object, the present invention includes a member that is fixed to the inner wall surface of the side wall constituting the machining tank and forms a machining fluid supply channel inside, and a tip end of this member that is connected to the machining fluid supply channel. A member is provided at the lower end of the interior to form a relatively wide machining fluid supply port that opens toward the inside of the machining tank, and the side wall opposite to the machining fluid supply port is provided with a member that forms a machining fluid supply port having a relatively wide width. The apparatus is characterized in that a liquid discharge port is provided to allow the machining liquid to flow throughout the entire interior of the machining tank and to be discharged.

Embodiments of the present invention will be explained below with reference to FIGS. 3 to 5, which show embodiments of the present invention.

Incidentally, parts that are the same as those of the prior art are indicated by the same reference numerals as in FIGS. 1 and 2.

In the figure, reference numeral 10 denotes a plate having an L-shaped cross section, and is connected to the inner surface of one side wall 1a of the processing tank 1 and the bottom wall 1b.
Both ends are fixed by welding to the inner surface of the pipe, and a machining fluid supply path a is formed therein.

11 is a plate having an L-shaped cross section with a machining fluid supply port 11a formed on the bottom side, and is connected to the tip of the machining fluid supply path a on the inner surface of the side wall 1C adjacent to the side wall 1a. It is fixed by welding.

12 is a machining fluid supply pipe connected to the machining fluid supply path a.

Reference numeral 13 designates a machining fluid discharge port, which is formed at the lower end of the side wall 1d opposite to the side wall 1C.

Since the present invention has the above configuration, the machining fluid supplied to the passage a via the machining fluid control device 5, the valve 6, and the piping 12 is supplied to the machining fluid supply port 11 at the lower end opening of the plate 11.
After flowing throughout the processing tank 1 as shown by the arrow from a, it is discharged to the outside from the discharge port 13.

Therefore, the machining fluid in the machining tank 1 is always maintained in a clean state, so that highly efficient electric discharge machining can be performed.
