Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cutting oil tank for machine tools, and more particularly to a cutting oil tank having a stirring function.

[Prior Art] Generally, in a machine tool, the cutting oil used during processing is temporarily stored in a cutting oil tank and then sent to a filter. It is being supplied.

[Problems to be Solved by the Invention] In the cutting oil tank, the minute chips mixed in the cutting oil spontaneously settle (some may be forced to settle) and the bottom of the tank Since it accumulates in the water, it is sometimes necessary to perform cleaning work to remove the precipitate. However, depending on the object to be processed (eg, graphite), the precipitate accumulated at the bottom of the cutting oil tank may solidify, which may make the tank cleaning operation difficult.

The present invention has been made in view of such a conventional situation, and an object thereof is to provide a cutting oil tank in which cutting chips in the cutting oil are prevented from precipitating as much as possible in the cutting oil tank. .

[Means for Solving the Problem] As a means for technically solving such a problem, according to the present invention, a nozzle pipe is erected at a corner portion in a cutting oil tank of a machine tool and each nozzle pipe is provided. Holes for discharging cutting oil are sequentially arranged in parallel on the side wall of the nozzle nozzle toward the next nozzle pipe, and the cutting oil mixed with cutting chips is discharged from these holes to a constant level in the cutting oil tank. The gist is that a vortex flow around the direction is generated.

[Operation] When the cutting oil is discharged from the nozzle pipe, a vortex flow is generated in the cutting oil tank and the stirring oil is constantly stirred, so that the precipitation of cutting chips in the cutting oil can be prevented as much as possible.

Embodiment Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment.

In FIG. 1, reference numeral 1 is a cutting oil tank, and nozzle tubes 2 are provided upright at four corners inside the tank. In the nozzle tube 2, oil discharge holes 2a are arranged on the side wall at regular intervals along the length direction, and the holes 2a are oriented toward the next nozzle tube in sequence. That is, in the case shown in the drawing, when the direction of the hole 2a of the nozzle tube 2 is traced in order, it turns counterclockwise. A branch pipe (not shown) branched from an oil feed pipe (not shown) is connected to the upper end of each nozzle pipe 2, and the lower end is brought into contact with the bottom surface of the cutting oil tank 1 or a lid member. It is preferable to attach and close each of them, but it may be in an open state.

The cutting oil tank according to the present invention is configured as described above,
When the cutting oil 3 used in the machine tool is fed into each nozzle pipe 2, it is discharged into the cutting oil tank 1 through the oil discharge holes 2a, and a counterclockwise vortex flow F is generated. Therefore, the cutting oil in the cutting oil tank 1 is always agitated naturally, and it is possible to prevent fine chips contained in the cutting oil from precipitating. Therefore, there is no accumulation of cutting chips or solidification on the bottom of the cutting oil tank 1,
Cleaning of the cutting oil tank 1 becomes easy.

The structure of the nozzle tube 2 is not limited to that of the above embodiment,
For example, the discharge direction may be set so that the discharge direction is such that a vortex flow is generated in the cutting oil tank. Further, the cutting oil tank is not limited to a rectangular shape, but can be a circular shape or any other shape. In particular, in the case of a circular cutting oil tank, swirling is likely to occur, so one nozzle tube It is also possible to carry out.

[Advantages of the Invention] As described above, according to the present invention, the nozzle pipe is provided in the cutting oil tank, and the vortex is generated by discharging the used cutting oil from the nozzle pipe. Since the inside of the oil tank is constantly agitated, it is possible to prevent the precipitation of fine chips contained in the cutting oil in advance, which prevents the accumulation and solidification of the precipitate and prevents the cutting oil tank. The effect of facilitating the cleaning of is obtained.
