Problems solved by technology

Therefore, the processing oil attached to the workpiece due to the processing operation is completely removed and washed away from the workpiece by the above-mentioned cleaning operation together with the cleaning solvent, the consumption of the processing oil increases, the operating cost increases, and the environment is affected. pollution also increased
[0007] In addition, since the workpiece to which a large amount of processing oil remains due to processing is directly cleaned, a large amount of cleaning solvent is required to remove the above-mentioned large amount of processing oil, which also leads to an increase in operating costs.
In addition, cleaning the workpiece with a large amount of processing oil with the cleaning solvent as described above will cause a large amount of processing oil to be mixed into the cleaning solvent, so the speed of contamination of the cleaning solvent will increase, and the replacement frequency of the cleaning solvent will increase accordingly. This also leads to higher operating costs

Embodiment 1

[0025] Embodiment 1 of the present invention will be described in detail with reference to the accompanying drawings. 1 represents a storage tank, and the inlet and outlet 2 at the upper end thereof are covered by a cover body 3 and can be opened and closed. like figure 1 As shown, the processing oil 4 is stored in the storage tank 1 , and the processing oil 4 can be heated by the heating mechanism 5 arranged in the storage tank 1 . Furthermore, a temperature sensor 9 is arranged in the storage tank 1 , and a processing oil tank 8 is connected through an overflow pipe 7 provided with a first on-off valve 6 . In addition, a first liquid level sensor 16 is provided in the storage tank 1, and when the liquid level of the machining oil 4 in the storage tank 1 reaches a certain value or more, the first liquid level sensor 16 is set according to a signal from the first liquid level sensor 16. The on-off valve 6 is opened, and the machining oil 4 can be introduced into the machining...

Embodiment 2

[0047] In the experimental method of Example 2 of this experiment, the oil temperature of the processing oil 4 at normal temperature is set to 32°C, and the oil temperature of the heated processing oil 4 is set to 72°C, 115°C, and 153°C. Example 1 is the same. The experimental results of Example 2 are shown in Table 3.

Abstract

The present invention provides a treatment method for reducing amount of processing oil adhered on a processed object and a device thereof. A simple method is used for reducing the amount of the processing oil adhered on the processed object for removing. The processing oil can be recycled, and simultaneously the cleaning solvent required in cleaning the processed object is reduced. Or the amountof the cleaning solvent is reduced to zero. Therefore the operation cost is reduced, and the pollution to the environment of the globe is reduced. According to the invention, the processing oil (4) which is same with the processing oil in the processing operation of the processed object (12) is heated to a temperature higher than an oil temperature in the processing operation for reducing the viscosity, and the heated processing oil (4) contacts with the processed object (12) which is adhered with the processing oil. Therefore the viscosity of the processing oil adhered on the processed object (12) is reduced for reducing the adhesion amount.

Description

technical field [0001] The present invention relates to a method for reducing the residual amount of processing oil adhering to the processed object during the processing operations of the processed object such as cutting, grinding, stamping, deep drawing, punching, drawing, forging, etc. Treatment method and device thereof. Background technique [0002] In the past, when cutting, grinding, stamping, deep drawing, punching, drawing, forging, etc., for the purpose of suppressing friction and cooling the workpiece, it was used to adhere to the workpiece, so A large amount of processing oil remains attached to the workpiece after the above-mentioned processing operation. The processing oil remaining on the workpiece needs to be removed or reduced from the surface of the workpiece so that it can be used in the next step. Therefore, as described in Patent Document 1, it is common to spray a cleaning solvent onto the workpiece after the above-mentioned machining operation or to ...
