Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stir bar with a gauge for diluting and mixing a stock solution of a water-soluble cutting fluid and water at a desired magnification and in a correct order.

[0002]

2. Description of the Related Art Generally, a water-soluble cutting fluid such as an emulsion type is used for cutting a work material using a band saw machine or the like. The functions of the cutting fluid include lubrication, cooling, prevention of welding of the work material to the cutting edge, and cleaning, and the like. The effect is great and it has been widely used.

[0003]

[Problems to be Solved by the Invention] By the way, in the above-mentioned water-soluble cutting fluid, the undiluted solution is diluted with water at the time of use, and the mixing ratio varies depending on the material of the work material (normally 5 to 5). 20 times), unless the cutting fluid diluted at an appropriate magnification is always used, the above-described effects cannot be sufficiently exerted. Also, regarding the mixing procedure,
In particular, in the case of an emulsion type cutting fluid, it is necessary to put water first, then add a stock solution and stir well.
In other words, in this type of cutting fluid, it is necessary to be in an emulsified state in which the stock solution particles are scattered in water, but when water is added to the stock solution, such a form is not obtained, and the stock solution that does not emulsify Is formed, which also causes the above-described effects to be unable to be exerted.

[0004] However, such a mixture of the stock solution of the water-soluble cutting fluid and water is generally carried out in a factory by hands of an on-site worker. Some 2
The fact is that it is mixed in a 0 liter can or the like with the aim of the worker. In addition, the procedure is usually performed in an erroneous manner, in which the undiluted solution is first put and then water is injected. Conventional densitometers such as hand-held refractometers are very expensive, and require a test solution to be set each time. It can be said that there are almost no examples used in the field.

[0005] From the above, at present, even in the case of a water-soluble cutting fluid that exhibits excellent effects when used correctly, the effects have not actually been fully utilized. The present invention has been made in view of such a point,
With a very simple structure, when mixing and diluting a water-soluble cutting fluid, the concentration control and procedure control can be easily performed, thereby fully utilizing the excellent effects of the water-soluble cutting fluid and using it as a stirring rod as it is. The aim is to provide a stir bar with a gauge that can be used.

[0006]

Means for Solving the Problems In order to achieve the above object, the stirring bar with a gauge of a water-soluble cutting fluid according to the present invention has a water surface scale that defines a water surface height at a predetermined distance from one end of the bar. In addition, a scale is provided between the scale and the other end of the rod to define a stock solution level corresponding to a plurality of dilution rates.

[0007]

[Function] For example, a container having a uniform inner cross-sectional area in the height direction, such as a normal 20-liter can, is used, and the stirring rod of the present invention is inserted substantially vertically so that one end side is down. In this state, water is poured into the can to the scale of the water surface, and the undiluted solution is poured from above until the liquid surface reaches the scale of the required dilution ratio. Finally, the inside of the can is stirred with the stirring rod. With this method of use, it is possible to simultaneously control both the mixing procedure and the concentration,
Separately, it is not necessary to prepare a stirring rod such as a piece of wood.

[0008]

FIG. 1 is an external view of an embodiment of the present invention. A water surface scale 2 serving as an indicator of the water surface is engraved on an acrylic stirring bar 1 at a predetermined distance from the lower end thereof,
Above this, a plurality of magnification scales 3a to 3n from 20 to 5 times are engraved. As shown in FIG. 2, the method of using the embodiment of the present invention is to prepare a container having a uniform cross-sectional area in the height direction, such as a 20-liter can at any factory, and to store the inside of the present invention inside the container. Is inserted almost vertically so that the water surface scale 2 is lower than the magnification scales 3a... 3n. In this state, water is injected until the water surface matches the water surface scale 2. Next, a stock solution of the cutting fluid is injected from above, and stopped when the liquid level matches the scale of the desired dilution ratio. After that, the inside of the container is sufficiently stirred by the stirring rod 1.

[0009] The above-mentioned dilution and mixing operation merely involves injecting water and a stock solution into a container according to a scale and stirring the solution.
It can be easily and reliably performed by anyone, and the resulting cutting fluid will be diluted in the correct procedure and at the correct concentration, and will fully demonstrate the functions inherent to the cutting fluid Can be done. In addition, as the material of the stirring rod of the present invention, any resin other than acrylic, and further, any material such as metal and wood can be used. Also, regarding the cross-sectional shape and lengthwise shape of the stirring rod,
Any shape can be used as long as it can be stirred by hand.

Further, it is needless to say that the stirring rod of the present invention can be applied not only to the water-soluble cutting fluid for a band saw machine but also to the water-soluble cutting fluid in all machine tools.

[0011]

[Effects of the Invention] As described above, according to the present invention, the scale of water is attached to the lower part of the stirring bar and the scale corresponding to the dilution ratio of the stock solution is attached to the upper part, making it extremely simple. With such a configuration, it is possible to completely prevent a mistake in the procedure when diluting the stock solution of the water-soluble cutting fluid, and to easily dilute the solution to a desired concentration.

In addition, in view of the fact that the method of use is extremely simple compared to conventional refractometers and the like, and in view of the actual situation of the work of diluting the conventional water-soluble cutting fluid, the use of the present invention allows Can always fully exhibit the original function of the cutting fluid that has not been fully demonstrated.
Further, the present invention is a tool which is particularly suitable for use in a production site, etc., since the present invention is low-cost, has no fear of failure, etc., and has one role of a diluting gauge and a stirring bar with one rod. You can say that.
