Automatic supply control system for water-soluble cutting oil

Abstract

The present invention relates to an automatic supply control system for water-soluble cutting oil. The control system is characterized in that the control system comprises an auxiliary tank (100), a main tank (200) and a PLC control unit (300); the auxiliary tank (100) has a first sensor (110) for sensing, through a PLC control unit, an amount of water to be supplied to the auxiliary tank, a first solenoid valve (120) for controlling the supply water by being linked with the first sensor (110) and the PLC control unit, a second sensor (130) for sensing, through the PLC control unit, the amount and the density of a lubricant to be supplied, a second solenoid valve (140) for controlling the supply of lubricant by being linked with the second sensor and the PLC control unit, a first stirring motor (150) for mixing, in a constant concentration ratio, the water and the lubricant to be supplied through the first / second solenoid valves (120, 140), and a transfer motor (160) for transferring the mixed water-soluble cutting oil to a main tank; the main tank (200) has a third sensor (210) for sensing, through the PLC control unit, the amount and the concentration of the water-soluble cutting oil transferred through the transfer motor (160) of the auxiliary tank (100), an overflow sensor (220) for preventing the transferred water-soluble cutting oil from overflowing from the main tank, a second stirring motor (230) provided in the center of a bottom of the main tank (200) and intermittently implementing stirring according to a control program of the PLC control unit so as to prevent the water-soluble cutting oil stored in the main tank (200) from spoiling, and a discharge motor (240) for discharging, to a machining device, the water-soluble cutting oil temporarily stored in the main tank (200); the PLC control unit (300) is used for respectively controlling the auxiliary tank (100), the main tank (200), and a user operation panel; and the user operation panel is for automatically and manually driving the control system and comprises: a seven-inch touch screen (400) having an initial screen (410), an automatic operation screen (420), a concentration control screen (430), a manual operation screen (440), an alarm history screen (450), and a manager mode (460); an automatic operation button (500); an alarm (600) for warning of an abnormality occurrence, and a reset button (700) for canceling the alarm; and an emergency stop button (800) for forcibly stopping the control system during an emergency. The automatic supply control system for water-soluble cutting oil provides unique effects of easily producing water-soluble cutting oil to be used in a machining device and the like, and maintaining the homogeneity of an emulsion even when a device is not used.

Description

technical field [0001] The present invention relates to an automatic supply control system for water-soluble cutting fluid, in particular, it relates to automatically mixing oil and water in a prescribed ratio by means of a programmable logic control (PLC) detection sensor and a touch screen of a user operation panel, so that the cutting fluid can be easily supplied to the cutting fluid. Liquid water-soluble cutting fluid automatic supply control system. Background technique [0002] In general, cutting fluids are liquids used for cooling and lubricating tools in machining. That is, cutting fluid is an oil applied to a tool in order to remove heat generated by reducing friction when machining a metal material, refine the machined surface, and protect the tool. [0003] There are many types of cutting fluids, such as oil, mixture of oil and water, paste, gel, spray and so on. Cutting fluid can be prepared by purifying crude oil or animal fat, food oil, etc., which depends o...
