Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a device for automatically proportioning cutting fluid. Background Art

[0002] When machining workpieces with mechanical processing equipment, it is necessary to spray cutting fluid at the position where the tool cuts the workpiece to cool the tool and prevent the workpiece from rusting. The cutting fluids used are prepared in advance. To prepare the cutting fluid, it is necessary to mix the cutting fluid concentrate and water to obtain a cutting fluid of a certain concentration.

[0003] At present, there are generally two ways to replenish cutting fluid for equipment in the mechanical processing industry. One way is to use hard water with a certain pressure through an automatic proportioning pump to achieve automatic proportioning of cutting fluid. Although the proportioning is convenient, the hardness of the cutting fluid will increase over time, which will lead to soap precipitation of the cutting fluid, reduce the processing quality of the tool, reduce the service life of the cutting fluid, increase the cost, and bring trouble to the user. The other way is to make pure water in advance through a pure water machine and store it in batches next to the equipment. When the cutting fluid needs to be added, it is manually proportioned, which is time-consuming and labor-intensive and the measurement is inaccurate. Utility Model Content

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the utility model discloses an automatic proportioning cutting fluid device, including a pure water tank 4, a self-priming pump 5, an automatic proportioning pump 7 and a cutting fluid stock barrel 8, the self-priming pump 5 includes a water inlet and a water outlet, the water inlet is connected to the pure water tank 4 through a hose or a hard pipe, the water outlet is connected to the automatic proportioning pump 7 through a hose or a hard pipe, a solenoid valve 6 is arranged on the pipeline between the self-priming pump 5 and the automatic proportioning pump 7, the automatic proportioning pump 7 is connected to the cutting fluid stock barrel 8 through a pipeline, the automatic proportioning pump 7 is used to mix pure water with cutting fluid stock to form a cutting fluid of a set ratio, the automatic proportioning pump 7 is connected to one end of a liquid outlet pipe 9, and the other end of the liquid outlet pipe 9 is connected to the cutting fluid water tank The cutting fluid proportioned by the automatic proportioning pump 7 is connected to the cutting fluid water tank to ensure the normal use of the processing equipment. Furthermore, a liquid level sensor is provided on the cutting fluid water tank, and the liquid level sensor is electrically connected to the solenoid valve 6. The liquid level in the cutting fluid water tank is detected by the liquid level sensor. When the cutting fluid in the cutting fluid water tank reaches the lower limit liquid level, the liquid level sensor transmits a signal to the solenoid valve 6, and the solenoid valve 6 opens. The self-priming pump 5 draws pure water to the automatic proportioning pump 7, and the automatic proportioning pump 7 mixes the water according to the set ratio to obtain the cutting fluid of the set concentration. The proportioning process is simple, does not require manual operation, saves time and effort, and the proportioning and metering are accurate. The automatic proportioning pump 7 is an automatic mixing proportion pump in the prior art.

[0022] The equipment for automatically proportioning cutting fluid also includes a pure water machine 2, which is used to prepare pure water. The pure water machine 2 includes a raw water inlet pipe 1 and a pure water outlet pipe. The pure water outlet pipe is connected to the pure water tank 4. The raw water inlet pipe 1 can be connected to tap water. The pure water machine 2 adopts an existing multi-stage filtration industrial pure water machine. The pure water machine 2 includes a pretreatment component, a fine treatment component and a post-treatment component connected by pipelines. The pretreatment component includes quartz sand and activated carbon. The quartz sand and activated carbon can effectively remove suspended matter, sediment, particles, and organic silica gel in the raw water. The fine treatment component includes a hollow fiber ultrafiltration membrane. Water flows through the hollow fiber membrane rod under pressure to remove bacteria. The post-treatment component includes a reverse osmosis membrane and a booster pump. The booster pump applies a certain pressure to the raw water passing through the reverse osmosis membrane. Under the action of pressure, water molecules in the raw water can pass through the membrane and dialyze out, while other inorganic salts, microorganisms and organic matter cannot pass through the reverse osmosis membrane due to the retention characteristics of the reverse osmosis membrane for these substances. Therefore, pure ion-free water, i.e. pure water, can be obtained, and the concentrated water can be directly discharged or collected for reuse.

[0023] A float switch assembly is provided at the pure water outlet pipe, and the float switch assembly includes a valve body, a support rod 3, a float 10 and a valve core 11.

The valve core 11 is slidably installed in the valve body. One end of an L-shaped connecting rod 12 is hinged to the valve core 11, and the other end is connected to the support rod 3. A water inlet port is provided at one end of the valve body, and a water outlet port is provided on the bottom wall. When the liquid level in the pure water tank 4 rises, the float 10 drives one end of the support rod 3 to move upward, thereby driving the valve core 11 to move to the right through the connecting rod 12 until the valve core 11 closes the water outlet port, and the pure water machine 2 stops working and stops supplying pure water to the pure water tank 4; when the liquid level in the pure water tank 4 decreases, the float 10 drives one end of the support rod 3 to move downward, thereby driving the valve core 11 to move to the left through the connecting rod 12 until the valve core 11 opens the water outlet port, and continues to supply pure water to the pure water tank 4, ensuring that the liquid level in the pure water tank 4 is maintained at the set liquid level height.
