Single-box vacuum oil immersion device and oil immersion method

Abstract

The invention discloses a single-box vacuum oil immersion device for powder metallurgy parts and an oil immersion method thereof. The single-box vacuum oil immersion device and the oil immersion method thereof are characterized in that the oil immersion device comprises an airtight oil immersion box which is composed of a box cover and a box body, a vacuum pump which is connected with the oil immersion box through an air duct, an object storing plate placed in the oil immersion box, and a tilting mechanism used for tilting the object storing plate or a lifting mechanism used for lifting the object storing plate; a vacuum meter and a deflation valve are arranged on the box cover or the upper portion of the side wall of the box body, a pressure retaining valve is arranged on the air duct, the tilting mechanism or the lifting mechanism is fixedly arranged on the box body, and a heating pipe is arranged at the bottom of the box body. The single-box vacuum oil immersion device is easy to manufacture, low in weight, convenient to operate, small in testing cost and high in testing efficiency. By the adoption of the single-box vacuum oil immersion device and the oil immersion method thereof, compared with an existing vacuum device, the oil immersion effect is the same.

Description

technical field [0001] The invention relates to a vacuum oil immersion device and an oil immersion method thereof, in particular to a vacuum oil immersion device and an oil immersion method for powder metallurgy parts. Background technique [0002] Vacuum oil immersion of powder metallurgy parts is to put the parts to be oiled into a vacuumable container. Firstly, vacuum the container to make the parts in a certain vacuum state. The oil storage tank is injected into the vacuum container. Since the parts are in a negative pressure environment, the injected lubricating oil will enter the gaps of the parts, and the speed of oil immersion is relatively fast, and the final oil content of the parts is relatively high. The vacuum oil immersion device in the prior art includes an oil storage tank and an oil immersion tank, or includes two parts equivalent to the oil storage tank and the oil immersion tank, such as the technical solution disclosed in the utility model patent specific...

AI Technical Summary

Problems solved by technology

This prior art vacuum oil immersion device, because it adopts two casings, causes complex structure, various connecting pipes, heavy device, relatively large volume, is generally suitable for industrial use, and one-time use lubricating oil reaches 200Kg, is applicable to The production of parts in large quantities; But, for the parts that are in the experimental stage, especially to the test of lubricating oil, it is necessary to prepare different types of lubricating oil, and adopt the vacuum device in the prior art, the amount of lubricating oil that needs to be prepared at one time is very large If the test result of the prepared lubricating oil is unsatisfactory, a large amount of lubricating oil may be wasted; and the labor load is relatively large when changing the lubricating oil

In addition, vacuum oil immersion sometimes needs to heat the lubricating oil. For existing industrial vacuum oil immersion devices, even if the number of parts to be oiled is small or there are only a few test samples, a large amount of lubricating oil needs to be heated. All the oil is heated to the set temperature, resulting in waste of resources
