Problems solved by technology
However, the process is slow, usually taking 2-12 hours, and it is not effective at all to guarantee the reliable removal of cutting oil
In addition, the recycling process needs to occupy a large space for a long time, which cannot effectively meet the needs of large-scale and rapid production. It not only makes the production cycle longer, but also easily pollutes the workshop site.

The invention relates to the field of mechanical engineering, and discloses an oil drain device. The oil drain device comprises an oil drain piston (30). The oil drain piston (30) can be inserted intoan oil cylinder body (10) and moves along the inner side wall surface (11) of the oil cylinder body (10). The oil drain piston (30) is provided with a partition part (31) capable of dividing a cylinder body cavity of the oil cylinder body (10) into a power cavity (12) and an oil drain cavity (13) with an opening on one end, so that the driving force of power cavity (12) is used to enable the partition part (31) to move along the inner side wall surface (11)in the direction of the opening of the oil drain cavity (13) to push cutting oil which is attached to the inner side wall surface (11), sothat the residual oil is quickly and reliably eliminated from the oil cylinder body (10), the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the field of mechanical engineering, in particular to an oil discharge device. Background technique [0002] As a commonly used drive unit in the field of mechanical engineering, oil cylinders are widely used in all walks of life and have great demand. As one of the important processes for processing oil cylinders, scraping and rolling processing requires a large amount of cutting oil during the processing, and these cutting oils are likely to remain in the inner wall of the cylinder, resulting in waste of cutting oil. [0003] Usually, about 50 grams of cutting oil will adhere to the cylinder body of a 3-meter oil cylinder after processing, and the adhesion amount of 4-meter, 6-meter, and 10-meter oil cylinders is even greater. If the residual cutting oil can be recovered and reused, the cost can be saved. For example, if the cutting oil is calculated at the market price of 11 yuan / 500 grams, the cost of more than 2,000 yuan...
