Description

Technical Field

[0001] The utility model relates to the technical field of metal machining equipment, in particular to a cutting fluid automatic proportioning and supplying device. Background Art

[0002] In the cutting process in machine tools, the supply of cutting fluid is a key link. The cutting fluid is used to lubricate the contact area between the workpiece and the tool, cool the cutting heat, remove chips, extend the tool life and ensure processing stability.

[0003] Since cutting fluid is rich in nutrients and is very easy to breed bacteria, it will cause the cutting fluid to deteriorate and stink. At the same time, various impurities generated during the processing process also accelerate the reproduction of bacteria, increase the frequency of cutting fluid replacement, and thus increase production costs. On the other hand, the traditional method of mixing cutting fluid is to first manually mix the stock liquid and water, then stir it manually, and then pour the cutting fluid into the cutting fluid supply equipment. This method is not only time-consuming and labor-intensive, but also has inaccurate concentration. In addition, the existing cutting fluid supply equipment can only supply cutting fluid to one metal processing equipment alone, and cannot supply cutting fluid to multiple metal processing equipment at the same time. In reality, multiple cutting fluid supply equipment needs to be equipped at the same time during the metal processing process, which not only occupies a large area, but also has a high cost of configuring the equipment.

[0043] By adopting the above technical scheme, the implementation method of this embodiment is as follows: 1. When supplying cutting fluid, the electric control box 34 is in the open state. The concentration of the supply fluid can be set and regulated through the electric control box 34, and other parameters can be set. The liquid supply pipe 35 selectively supplies liquid to different machine tools, and at the same time monitors the state of the cutting fluid and regulates the working power of the liquid supply pump 15. In the automatic mode, the liquid replenishment mode of the liquid outlet at the machine tool end is divided into automatic and manual. The cutting fluid replenishment mode can be switched by the control box 37. In the automatic mode, automatic liquid replenishment can be achieved through the signal of the liquid level meter 26. In the manual mode, it is necessary to manually start the liquid discharge valve to replenish the liquid after manually observing the liquid level of the machine tool water tank. 2. During the reflux process of the cutting fluid, the electric control box 34 is in the open state to detect and control the working state and working parameters of each component. Each machine tool water tank is connected to the cutting fluid reflux pool. First, the pneumatic three-way valve 31 cooperates with the control box 37 to control the opening and stopping time of the upper return liquid port and draws the floating oil on the liquid level surface of the cutting fluid return pool 29 back to the return liquid device 6 and discharges it. The upper return liquid port collector 33 collects the floating oil on the liquid level surface and transports it back to the return liquid device 6 and discharges it; the lower return liquid port is normally open, and then the cutting fluid in the cutting fluid return pool 29 is transported to the circulating return liquid pipeline 36 through the return pump; in the automatic mode, the liquid level of the cutting fluid in the cutting fluid return pool 29 can be monitored by the liquid level meter 26 to adjust the working power of the return liquid pump 16. Then the return liquid flows through the drum filter 19, the pipeline backwash filter 20, the pressure-maintaining filter 21, the return liquid circulation pre-filtration area 22, the ozone generator 14, the pH value monitor 13, the raw liquid pump 12, the circulating oil removal and sterilization fine filtration area 23, the bag skimmer 18, and the circulating return liquid concentration detection and proportioning area 24 in sequence. Then, the cutting fluid with the best concentration is intelligently proportioned through the combination of the liquid level meter 26 and the raw liquid pump 12 and transported to the new liquid intelligent proportioning storage tank 25 for standby use. When the machine tool needs to be stopped for a long time and the cutting fluid at the machine tool end needs to be emptied, the control box 37 can be used to cooperate with the electric control box 34 and the reflux pump to pump the cutting fluid into the liquid storage tank 2.

[0044] Under normal working conditions, the total amount of supply liquid is greater than the total amount of reflux liquid, which enables the return liquid device 6 to timely transport the old liquid back to the circulating reflux liquid pipeline 36 and the liquid storage tank 2, and filter, degrease, ozone sterilize, fine filter, replenish cutting fluid stock liquid and other operations to keep the cutting fluid in use clean and the concentration value within the optimal concentration range.
