(2) The invention relates to tapping oil, wherein the 52# chlorinated paraffin can be combined with first-grade solid rosin and 32# white oil without chemical reaction, and forms a thick state due to the dilution of the first-grade solid rosin after cooling, can not crystallize at minus 16 ℃ and can still flow slowly, when in use, because the workpiece can generate high temperature in the processing process, the thick tapping oil can be changed into liquid state after meeting the high temperature, in conclusion, the tapping oil can continuously provide cooling and lubrication for the screw tap or the cutter during cutting, obviously reduce the abrasion of the screw tap or the cutter, improve the production efficiency and reduce the production cost, and meanwhile, the tapping oil contains few components and is easy to obtain, so that the processing technology is simplified.

Detailed Description

For a further understanding of the present invention, reference will now be made in detail to the following examples.

Example 1

The tapping oil is prepared from 70% -80% of 52# chlorinated paraffin, 8% -14% of 32# white oil and 12% -16% of first-grade solid rosin. Here, it should be explained that: the first-grade solid rosin is rosin with a first grade and is in a solid state.

Preferably, the tapping oil provided by the invention comprises 76% -80% of 52# chlorinated paraffin, 8% -11% of 32# white oil and 12% -15% of first-stage solid rosin in proportion.

More preferably, the mass ratio of the first-grade solid rosin to the 32# white oil in the tapping oil provided by the invention is 1.5: 1.

Most preferably, the tapping oil provided by the invention comprises 80% of 52# chlorinated paraffin, 8% of 32# white oil and 12% of first-stage solid rosin.

The preparation method of the tapping oil comprises the following steps:

Mixing the components according to a certain proportion, heating while stirring, wherein the heating temperature is 70 ℃, the heating time is 30 minutes, and standing for 8 hours to obtain the product. Here, it should be noted that: the two process parameters of the heating temperature and the heating time are obtained by long-term tests and theoretical analysis of an applicant, and the service performance of the tapping oil can be obviously improved through the specific setting of the two process parameters.

It should be noted that: the applicant creatively discovers that the addition of the first-stage solid rosin can remove pungent gas generated when 52# chlorinated paraffin meets high temperature, can enhance viscosity, ensures that the prepared tapping oil is in a thick state, can form an oxidation diaphragm on the surface of a workpiece when in use, and prevents the workpiece from being oxidized, in addition, the addition of the 52# chlorinated paraffin not only plays a role in flame retardance on the first-stage solid rosin, improves the use safety, but also plays a role in plasticization, and simultaneously, the 32# white oil plays a role in non-corrosive high-precision lubrication.

It needs to be further explained that: the 52# chlorinated paraffin in the tapping oil can be combined with the first-stage solid rosin and the 32# white oil and does not generate chemical reaction, a thick state is formed due to dilution of the first-stage solid rosin after cooling, crystallization cannot occur at the temperature of-16 ℃, and the chlorinated paraffin can still flow slowly, when the tapping oil is used, the thick tapping oil can be changed into a liquid state due to high temperature generated in a workpiece in a processing process when meeting high temperature, and the transition process from the thick state to the liquid state is a heat absorption process, so that efficient cooling of the front section of the screw tap or the cutter can be realized.

It should be further noted that: although the tapping oil only contains three components, the technical scheme of the application cannot be obtained on the basis of numerous experiments and theoretical analysis, namely the applicant obtains the technical scheme of the application through numerous experiments, the thick tapping oil can be prepared through the technical scheme, in order to further verify the using effect of the thick tapping oil, the applicant conducts tests of M6, M8, M10 and M12 on 304 stainless steel with the thickness of 25mm processed at 57mm and 75mm, and under the auxiliary work of an electric tapping machine, the uniform processing is completed for many times, the middle of the tapping is not stopped, the tapping is not rattled, and the tap is not damaged after the processing is finished and the wiping inspection is conducted. The method is applied to processing of various materials in a workshop, and the consistent excellent comments of a workshop master are obtained. In summary, the thick tapping oil can be processed and formed at one time and can be applied to various metal materials.

The tapping oil in the invention is prepared by the applicant after numerous tests, and 7 groups of tests in the following table are for more clearly and intuitively showing the creative work of the applicant to obtain the thick tapping oil in the invention. (Note that the greater the thickness, the greater the difficulty of processing the 304 stainless steel material)
