Description

Electric rust prevention method for machining machine tool
Technical Field
The invention relates to the field of machining, in particular to an electric rust prevention method for a machining machine tool.
Background
Development of cutting technology hardware is mainly reflected in improvements in machine tool and cutter technology. With the development of scientific technology, machine tools perform machining under high-efficiency, high-precision and high-quality conditions. The existing machine tool enters the era of numerical control machine tools, the existing high-end machine tool has higher vibration resistance, machining precision and efficiency, the service life and reliability of the machine tool are also improved, and rust prevention of the machine tool is an important ring for influencing the service life of the machine tool.
The cutting fluid is an industrial fluid which is used for cooling and lubricating a cutter and a workpiece in the metal cutting and grinding process and has the characteristics of good cooling performance, lubricating performance, rust resistance, oil removal cleaning function, corrosion prevention function and easy dilution. Among the several common machining modes, the most resources are consumed for cutting and grinding and the most impact on the environment is the greatest, one of the more important factors is the use of cutting fluid. The cutting and grinding are carried out by contacting with the metal blank in a large area, and the metal is processed, so that the service life of the cutter is shortened and the replacement period is shortened due to the fact that the resistance on the surface of the metal ingredients is large and the generated heat is high. The oil-based cutting fluid wastewater contains a large amount of emulsified oil, metal chips, organic matters and the like, and has high COD, total Organic Carbon (TOC) and oil concentration. If the untreated oil-based cutting fluid wastewater is discharged into a natural water body, an oil film can be formed on the water surface, so that the water body is anoxic, and the growth of organisms in water is threatened. In addition, grease in the cutting fluid wastewater has stronger permeability, and can also penetrate soil to enter an underground water layer so as to pollute an underground water source. After the additives and metal scraps in the wastewater enter the water circulation, the additives and metal scraps can enter a human body through a food chain, so that the risk of cancer is caused, and the human health is endangered. The water-based cutting fluid has lighter influence on the environment than the oil-based cutting fluid, but even if the rust-proof component is added into the water-based cutting fluid, the machine tool and the workbench can rust after a period of time.
The traditional oil-based cutting fluid has serious environmental pollution, so that the environment protection of the cutting fluid is improved when the environment-friendly machining is realized, and the water-based cutting fluid can cause rust of a machine tool and a workbench. New rust inhibitive technologies for water-based cutting fluids are sought to avoid and ameliorate this effect.

Further, the cutting fluid filtering and circulating system is used for realizing the filtering and purifying and the recycling of the water-based cutting fluid, and the inlet and the outlet of the cutting fluid filtering and circulating system are respectively connected with the water outlet and the water inlet of the cutting fluid collecting tank.
Still further, the cutting fluid in the cutting fluid collecting tank flows into the magnetic separator from the water outlet, metal scraps are roughly removed by the magnetic separator, other liquid enters the chip sedimentation tank for chip sedimentation, meanwhile, the settled chips are subjected to electric rust prevention treatment so as to prevent water quality pollution, then the liquid is pumped out of the sedimentation tank through a water pump, firstly, the impurity with the particle size of more than or equal to 5 mu m in the liquid is removed through a filter, then the liquid is pushed to a reverse osmosis membrane through a high pressure pump, and the impurity with the particle size of more than or equal to 10 mu m is removed 4 And particles and ions with the diameter of mu m, and flowing the refined cutting fluid into a water reservoir, measuring indexes such as conductivity, turbidity and the like of the cutting fluid in the water reservoir by a sensor, and pumping the cutting fluid in the water reservoir to a water inlet by a water pump to be discharged into a cutting fluid collecting tank, so that the cleaning circulation of the cutting fluid is realized.

The technical conception of the invention is as follows: typically, iron-containing workpieces develop rust in water due to Fe 2+ Is etched in water. In order to prevent the workpiece and the machine tool from rusting without adding an antirust component in the machining process using the water-based cutting fluid, an electric antirust method is used for rust prevention.

Fe→Fe 2+ +2e - (1)
(1/2)O 2 +H 2 O+2e - →2OH - (2)
The circulating purification and the deionization of the water-based cutting fluid can be realized through the cutting fluid filtering and circulating system. Wherein, the electric rust prevention of the chip sedimentation tank can prevent chips from rusting and pollute the water quality. The removal of the reverse osmosis membrane is more than or equal to 10- 4 Particles and ions of μm, prevent the particles from scratching the workpiece and prevent contaminants (rust, ions, etc.) from adhering to the workpiece. The performance of the reverse osmosis membrane is improved by using the high-pressure pump, so that the purification capacity of the system and the flow rate of the refined water-based cutting fluid are improved.
