Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic processing oil blending device for diluting a stock solution and automatically blending it to an appropriate concentration in order to smoothly perform machining such as cutting and grinding.

[0002]

2. Description of the Related Art Normally, in the processing such as cutting and grinding,
It requires the use of processing oil, the main function of which is to facilitate machine operation, such as by cooling and lubricating. That is, first of all, the cooling function is
The main purpose is to reliably and efficiently take away heat generated by frictional contact between a processing machine and a workpiece or heat generated by deformation of a work. And this cooling function
Depends on the capacity (concentration) of processing oil. Secondly, the lubrication function is to lubricate the interface between the tool and the work material such as cutting and grinding of the processing machine in order to reduce the wear and power consumption of the processing machine. The lubricating function depends on the capacity (concentration) of the processing oil. Thirdly, the function of the processing oil to reach the cutting edge, so-called permeability, also depends on the capacity (concentration) of the processing oil.

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 a stock solution diluted 10 to 100 times,
Although the dilution concentration varies depending on the purpose of processing, the type of work piece, the type of oil agent, etc., it is an appropriate value for the oil concentration that satisfies various conditions such as processability, rust prevention, and cooling effect, and is economical. Is set.

[0004] Normally, regardless of the type of water-soluble processing oil, once processed, it is used once and repeatedly circulated, and in the process of this circulation, water tends to evaporate and the oil content tends to thicken. On the other hand, the amount of the crude oil component is scattered, or the amount of the crude oil component is reduced while being attached to the material to be processed and carried out. Therefore, it is necessary to supplement the water-soluble processing oil prepared to have an appropriate concentration as needed. When replenishing this water-soluble processing oil, it is important to dilute the stock solution to an appropriate concentration that satisfies various conditions such as processability and cooling effect.

By the way, the blending of the processing oil is carried out by measuring the concentration with a concentration meter each time, and measuring the undiluted solution and water through a valve adjusting operation based on the measured value, and stirring and mixing. I was going. As the liquid metering and mixing system, the setting and adjustment of the mixing ratio of the liquid of JP-A-63-143930, the discharging or jetting method and the device thereof, and the liquid metering and mixing device of JP-A-63-278538 are scattered.

[0006]

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 content thereof is different from the adjustment of dilution of processing oil as in the present invention.

Therefore, according to the present invention, the water-soluble processing oil is diluted to an appropriate concentration by automatic or manual operation, and the prepared processing oil that has been precisely prepared is supplied to the processing machine oil storage tank at an appropriate concentration. It is to automatically generate the mixed processed oil and to supplement the mixed processed oil of an appropriate concentration as a secondary.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to downsizing of a device.
Achieving the above, the stock solution of processing oil can be

[0010]

Next, the operation of the present invention will be described.

In the case of manual operation, by pressing the stock solution pump switch, the stock solution is supplied to the stock solution tank by the pump, and when the stock solution is full, the pump is automatically stopped. And
By pressing the stock solution valve switch ,
Stock solution, piping and then through the valve supply of a certain amount measuring tank
When a certain amount is supplied and reaches a predetermined level, the level and body
Product, weight detection means, etc. (hereinafter referred to as level detection means)
The supply of the stock solution is stopped by the detection of the detection means.

Through the above operation, a fixed amount of undiluted solution is measured
By pressing the metering valve switch when it is supplied to the tank
A fixed amount of the undiluted solution in the measuring tank enters the mixing tank through the pipe. On the other hand, by pressing the industrial water valve switch, water (industrial water) is supplied until the mixing tank is full. In this way, the supplied undiluted solution and water are thoroughly stirred and mixed by the blades of the stirrer, which stirs the entire mixing tank evenly, and the processing oil diluted to a predetermined concentration is added here.
Are blended to produce blended processed oil.

In this state, for example, when a replenishment command signal is issued based on a command from the processing machine storage tank, the replenishment pump switch is pressed to cause the mixed processing oil in the preparation tank to replenish the piping and replenishment. As a general rule, the oil is supplied to the oil storage tank of the processing machine via a pump and automatically supplied until a predetermined level is reached, and when the predetermined level is reached, the supply of the mixed processing oil is stopped.

In the case of automatic operation, the above operation is automatically performed, and the stock solution in the measuring tank is measured by a replenishment command from the oil storage tank of the processing machine, and the stock solution and water are measured by a stirring blade in the mixing tank. The mixed and processed oil prepared by agitating and mixing is prepared to have an appropriate concentration, and automatically replenished to the oil storage tank of the processing machine.
