Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a processing machine that automatically prepares a blended processing oil produced by diluting an undiluted solution and automatically blending it to an appropriate concentration in order to smoothly perform machining such as cutting and grinding. The present invention relates to a device for manual replenishment.

[0002]

2. Description of the Related Art Normally, in the processing such as cutting and grinding,
It requires the use of processing oils, the main function of which is to facilitate machine operation by cooling and lubricating.

That is, the cooling function is to take away the heat generated by the frictional contact between the processing machine and the workpiece or the heat generated by the deformation of the work, and the cooling function depends on the capacity of the processing oil. It is said that.

The lubricating function is to lubricate the interface between the tool such as cutting and grinding of the processing machine and the work material in order to reduce the wear and power consumption of the processing machine. It is said that it depends on the ability of processing oil.

Furthermore, it is said that the function of the processed oil to reach the cutting edge, so-called permeability, also depends on the capacity of the processed oil.

[0006] The processing oil is usually a stock solution,
There are water-insoluble processing oil that is used as it is and water-soluble processing oil that is used by diluting with water.

The present invention mainly relates to the latter water-soluble processing oil.

By the way, this water-soluble processing oil is usually prepared by diluting the stock solution 10 to 100 times, and although the dilution concentration varies depending on the purpose of processing, the type of workpiece, the type of oil agent, etc. Satisfies various conditions such as rust resistance and cooling effect,
In addition, an appropriate value for the oil content is set in consideration of economy.

Normally, regardless of the type of water-soluble processing oil, once processed, it is used once and repeatedly circulated. In the process of cyclical use, water tends to evaporate and the oil content tends to thicken. On the other hand, the crude oil component is scattered,
The amount is reduced while adhering to the work material and being taken out.

Therefore, it is necessary to replenish the water-soluble processing oil prepared at an appropriate concentration as needed.

When replenishing the water-soluble processing oil, it is important to dilute the stock solution to an appropriate concentration so as to satisfy various conditions such as processability and cooling effect.

By the way, the blending of the processing oil is carried out by measuring the concentration of the processing oil each time, and measuring the undiluted solution and water through the valve adjusting work based on the measured value and stirring and mixing. I was going.

A liquid metering and mixing system is disclosed in Japanese Patent Laid-Open No. 63-63
-143930 Liquid-mixing ratio setting adjustment and its ejection or ejection method and its device, JP-A-63-27853
Liquid measuring and mixing equipment such as No. 8 can be seen here and there.

[0014]

As described above, when a mixed processing oil is produced, the mixing ratio of the processing oil is measured with a densitometer, and based on the measured value, the stock solution is adjusted through a valve adjusting operation. It is very troublesome and inefficient to measure the water and the water, and then mix and mix the undiluted solution and the water each time, and naturally, the concentration of the processing oil tends to vary. .

Further, the prior art documents are that the system is complicated and that liquids are mixed, and the contents are different from the dilution adjustment of the processing oil as in the present invention.

Therefore, according to the present invention, a water-soluble processing oil is diluted to an appropriate concentration by an automatic or manual operation, and a prepared processing oil precisely prepared is supplied to a processing machine oil storage tank. The automatic generation of and the replenishment device for this mixed processing oil.
