Embodiment 1

[0088] Mix the above polysulfides, thiadiazole derivatives, oily agents, and mineral oil in the amounts shown in Table 1-1 to obtain a kinematic viscosity of 89mm at 40°C 2 / s lubricating oil. With respect to the lubricating oil obtained, each processability was evaluated by the method mentioned above. The results are shown in Table 1-1.

Embodiment 2～9

[0090] In Example 1, lubricating oils having kinematic viscosities shown in Table 1-1 were obtained in the same manner except that the lubricating oil compositions were as shown in Table 1-1. Each of the lubricating oils obtained was subjected to the same processing performance evaluation as in Example 1, and the results are shown in Table 1-1.

[0091] Table 1-1

[0092]

Embodiment 4

[0100] In Example 4, except that the processed material was replaced with those shown in Table 2, the same processing performance evaluation was performed, and the results are shown in Table 2.

[0101] Table 2

[0102]

[0103] From the above results, it can be seen that the present invention has almost the same excellent processing performance as chlorine-based processing oils regardless of the workpiece, and can perform environmentally friendly production without deteriorating the working environment or generating odors.

[0104] In addition, it is possible to achieve low viscosity with almost the same performance as chlorine-based processing oil, and it is possible to save energy such as power consumption.

Abstract

Disclosed is a lubricant composition for fine blanking, which is an environmental-friendly chlorine-free working oil but still enables a die life comparable with the case where a chlorine-containing oil is used. The lubricant composition for fine blanking provides a product having a good shape. The lubricant composition for fine blanking contains 10-50% by mass of an active sulfur compound and 2-10% by mass of a thiadiazole derivative.

Description

technical field [0001] The present invention relates to a lubricating oil composition for fine blanking. Background technique [0002] Compared with the existing punching process, the fine blanking process has strict processing conditions such as long contact time between tools and materials, high heat generation, etc., and strict requirements are placed on the lubricating oil used. Therefore, in most cases, Chlorine-based oils are used as lubricating oils. However, this chlorine-based oil agent has been pointed out to be problematic in terms of safety to the human body, air pollution when burning lubricating oil waste liquid, and the like. [0003] Due to the above points, in the fine blanking process, the use of non-chlorine processing oil has been studied. As such non-chlorine-based machining oils, generally, changing the viscosity of conventional cold forging oils is the mainstream. For example, Patent Document 1 describes an example of using a typical cold forging oil...
