Description

Processing fluid interface lubrication formulation testing system Technical Field

[0001] This invention relates to the field of testing system technology, and in particular to a testing system for processing fluid interface lubrication blending formulations. Background Technology

[0002] Machining fluids primarily function as lubricants and coolants, while also providing rust prevention and cleaning. Common machining fluids include cutting fluids, cutting oils, emulsions, stamping oils, quenching agents, high-temperature oils, extreme-pressure cutting fluids, grinding fluids, rust-preventive oils, cleaning agents, blackening agents, and deep-drawing oils. Machining fluids are typically produced by mixing and reacting various chemical liquids to obtain a stable liquid form. Properly managed processes during the production of machining fluids are essential for quickly and effectively obtaining high-quality products.

[0003] Existing processing fluids generally require laboratory preparation, followed by verification of their concentration. However, factory processing fluids need to be used immediately after preparation, rather than stored for a period of time. This method can easily cause precipitation in the processing fluid, leading to significant differences in its performance. Furthermore, using a spray method for preparation can easily result in waste of processing fluid, increase the cost of mixing, and prevent further mixing of the prepared fluid, thus reducing the accuracy of the mixing ratio. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for a processing fluid interface lubrication blending formula testing system to address the shortcomings of existing technologies. This system not only allows for the separate storage of the blended processing fluid, but also enables the addition of small amounts of the processing fluid to be blended and mixed with the existing fluid for further blending to create new processing fluids. Alternatively, it allows for the cross-circulation of mixed processing fluids from different storage tanks to create new processing fluids, thus meeting the proportioning requirements of more formulas. Simultaneously, it allows for real-time data acquisition of various formulas and storage in different storage tanks, significantly reducing the cost of processing fluid blending and improving blending accuracy.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A processing fluid interface lubrication formulation testing system, characterized in that it includes:

[0007] At least two raw material delivery mechanisms are provided, which are used to store and deliver the processing liquid to be prepared;

[0008] The test bench is connected to the original liquid delivery mechanism and is used to frictionally mix the processing liquid to be prepared.

[0009] Control terminal, used for data transmission;

[0010] A closed liquid storage system, which connects the test bench and the raw liquid delivery mechanism, is used to store the prepared processing liquid;

[0011] The closed liquid storage system includes several liquid storage tanks connected in parallel. The inlet end of the liquid storage tank is connected to the test bench and the raw liquid delivery mechanism, and the outlet end of the liquid storage tank is connected to the test bench.

[0012] The processing fluid to be prepared is input into the test bench via the raw material delivery mechanism. The mixture is formed through friction on the test bench and then stored in a storage tank within a closed storage system. The control terminal receives data and controls the raw material delivery mechanism and storage tank, causing the processing fluid to be prepared and the mixed processing fluid to re-enter the test bench for further friction mixing, thus achieving cyclical preparation of the processing fluid. This structural design allows for the separate storage of the prepared processing fluid, and also enables the addition of small amounts of the processing fluid to be prepared and the mixed processing fluid for further preparation to form new processing fluids. Alternatively, the mixed processing fluids from different storage tanks can be cross-circulated to create new processing fluids, satisfying the formulation requirements of more formulas. Simultaneously, data from each formula can be collected in real time and stored in different storage tanks, significantly reducing the cost of processing fluid preparation and improving formulation accuracy.

[0013] Furthermore, each raw material delivery mechanism includes a raw material tank for storing the processing fluid to be prepared, a temperature controller for detecting the processing fluid to be prepared, and a first flow detection device for detecting the delivery volume of the processing fluid to be prepared. The temperature sensor is connected to the raw material tank, and the first flow detection device is connected to the raw material tank. The raw material tank can store the processing fluid to be prepared for initial and subsequent preparation of the processing fluid. The temperature controller is used to control the temperature of the processing fluid to be prepared to meet the preparation requirements of different processing fluids. The first flow detection device is used to detect the delivery volume of the processing fluid to be prepared, thereby improving the preparation accuracy.

[0014] Furthermore, the test bench includes a box for forming a sealed space, a substrate disposed inside the box, and a friction mechanism for mixing the processing fluid to be prepared. The friction mechanism is rotatably connected to the box, and the substrate is movably connected to the box through a load detection module and an inclination adjustment module. The raw liquid delivery mechanism inputs the processing fluid to be prepared between the friction mechanism and the substrate, and a gap liquid film is formed through the interaction between the friction mechanism and the substrate. The load detection module can control the pressure during friction based on the external force borne by the parts or components on the substrate during operation, and the inclination adjustment module controls the force-bearing surface during friction by controlling the inclination of the substrate.

[0015] Furthermore, the friction mechanism includes a hollow elastic grinding head, a sleeve that drives the elastic grinding head to rotate, and a variable frequency motor for driving the sleeve to rotate. The sleeve is rotatably connected to the housing through a gap adjuster. The elastic grinding head is connected to one end of the sleeve, and the other end of the sleeve is connected to a rotary sealing device. The variable frequency motor drives the sleeve to rotate at a variable speed, controlling the elastic grinding head to perform variable speed friction on the processing fluid to be prepared, thereby improving the preparation efficiency of the processing fluid. The prepared processing fluid can be transported outward through the sleeve through the interior of the elastic grinding head.

[0016] Furthermore, a friction gap is formed between the elastic grinding head and the substrate, and the distance of the friction gap is H, which ranges from 0 to 0.15 mm.

[0017] Furthermore, the enclosure is equipped with a temperature range generator and an altitude simulation device, which are used to control the temperature and pressure inside the enclosure, enabling it to operate under different temperatures and pressures.

[0018] Furthermore, between the raw material delivery mechanism and the test bench, there is a valve assembly for controlling the flow of the processing fluid to be prepared and / or the mixed processing fluid, a delivery pump for providing power during the delivery of the processing fluid to be prepared and / or the mixed processing fluid, an inlet flow detection device for detecting the delivery volume of the processing fluid to be prepared and / or the mixed processing fluid, an inlet pressure detection device for detecting the delivery pressure of the processing fluid to be prepared and / or the mixed processing fluid, and a guide pipe for inputting the processing fluid to be prepared and / or the mixed processing fluid into the friction gap. The guide pipe is located on the substrate and vertically penetrates the top surface of the substrate. The inlet pressure detection device is located between the guide pipe and the inlet flow detection device, and the delivery pump is located between the inlet flow detection device and the raw material delivery mechanism.

[0019] Furthermore, the closed liquid storage system is connected to the test bench via a cavitation generator. The cavitation generator includes a first outlet valve, a second outlet valve, and a cavitation pump. The second outlet valve is connected in series with the cavitation pump, and the first outlet valve is connected in parallel with the second outlet valve. When grinding is performed under fully enclosed conditions, bubbles will be generated due to the varying grinding speed. The first outlet valve is closed, the second outlet valve connected to the cavitation pump is opened, and the opening of the inlet valve is reduced. Bubbles are generated by the cavitation pump to simulate the effect of bubbles generated inside the grinding process. When it is not necessary to eliminate bubbles, the second outlet valve connected to the cavitation pump is closed, and the cavitation pump is shut down. The processing fluid enters the closed liquid storage system through the first outlet valve, completing the circulation of the processing fluid.

[0020] Furthermore, an outlet pressure detection device and an outlet flow detection device are installed between the test bench and the cavitation generator to detect the delivery pressure and delivery volume of the mixed processing fluid.

[0021] Furthermore, the testing system also includes an abrasive particle concentration control system, which includes a metering and recovery device, a safety valve, a recovery pump, a separation tank, and a second flow detection device. The metering and recovery device is connected to the test bench, the safety valve is located between the metering and recovery device and the recovery pump, and the separation tank is located between the recovery pump and the second flow detection device. The separation tank is equipped with an abrasive particle concentration detector. The metering and recovery device collects the leaked processing fluid from the test bench and recovers the abrasive particles through the centrifugal action of the safety valve and the recovery pump, reducing the loss of abrasive particles and allowing them to be reused. The separation tank can separate and filter the abrasive particles and waste liquid, and the output of abrasive particles is detected by the second flow detection device.

[0022] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0023] 1.

At the same time, data of each formula can be collected in real time and stored in different storage tanks, which greatly reduces the cost of processing fluid preparation and improves the accuracy of preparation.

[0024] 2. The variable frequency motor drives the sleeve to rotate at a variable speed, and controls the elastic grinding head to perform variable speed friction on the processing fluid to be prepared, thereby improving the efficiency of processing fluid preparation. The prepared processing fluid can be transported out through the sleeve through the inside of the elastic grinding head to meet the processing requirements of cutting fluid and grinding fluid.

[0025] 3. The cavitation generator is connected to the test bench. The cavitation generator includes a first outlet valve, a second outlet valve, and a cavitation pump. The second outlet valve is connected in series with the cavitation pump, and the first outlet valve is connected in parallel with the second outlet valve. When grinding is performed under fully enclosed conditions, bubbles will be generated due to the varying grinding speed. The first outlet valve is closed, the second outlet valve connected to the cavitation pump is opened, and the opening of the inlet valve is reduced. Bubbles are generated by the cavitation pump to simulate the effect of bubbles generated inside the grinding process. When it is not necessary to eliminate bubbles, the second outlet valve connected to the cavitation pump is closed, and the cavitation pump is shut down. The processing fluid enters the closed storage system through the first outlet valve, completing the circulation of the processing fluid.

[0026] 4. The metering and recovery device collects the leaked processing fluid from the test bench. Through the safety valve and the centrifugal action of the recovery pump, the abrasive particles are recovered, reducing the loss of abrasive particles and allowing them to be reused.

[0037] The test bench 10 is connected to the raw liquid delivery mechanism for friction mixing of the processing liquid to be prepared. The test bench 10 includes a box 34 for forming a closed space, a substrate 23 disposed in the box 34, and a friction mechanism for mixing the processing liquid to be prepared. The friction mechanism is rotatably connected to the box 34. The substrate 23 is movably connected to the box 34 through a load detection module 25 and an inclination adjustment module 26. Four or eight load detection modules 25 and inclination adjustment modules 26 can be set to ensure that the substrate 23 is subjected to balanced force when it is in a horizontal state.

[0038] The friction mechanism includes a hollow, elastic grinding head 27, a sleeve 28 that drives the elastic grinding head 27 to rotate, and a variable frequency motor 31 that drives the sleeve 28 to rotate. The sleeve 28 is rotatably connected to the housing 34 via a gap adjuster 29.

A second valve 5 is provided between the delivery pump 6 and the raw liquid delivery mechanism, and an inlet valve 7 is provided between the inlet flow rate detection device 8 and the delivery pump 6. In the prior art, the processing fluid is applied by spraying, which results in a large amount of processing fluid used, low utilization rate, and increased processing fluid preparation cost. In order to avoid this problem, the processing fluid is used in a precise and detailed manner. This application opens a hole in the center of the substrate, through which the processing fluid directly enters the test bench.

[0041] The closed liquid storage system 17 is connected to the test bench 10 and the raw liquid delivery mechanism, and is used to store the prepared processing liquid. The closed liquid storage system 17 includes several parallel liquid storage tanks 35. The inlet end of the liquid storage tank 35 is connected to the test bench 10 and the raw liquid delivery mechanism, and the outlet end of the liquid storage tank 35 is connected to the test bench 10. The inlet end and outlet end of the liquid storage tank 35 are respectively provided with a fourth valve 36 and a fifth valve 37. A third valve 18 is provided between the liquid storage tank 35 and the raw liquid delivery mechanism.

Bubbles are generated by the cavitation generating pump to simulate the effect of bubbles generated inside the grinding process. When it is not necessary to eliminate bubbles, the second outlet valve 15 connected to the cavitation generating pump 16 is closed, and the cavitation generating pump 16 is turned off. The processing fluid enters the closed liquid storage system 17 through the first outlet valve 14 to complete the circulation of the processing fluid.

A sixth valve 43 is provided between the separation tank 41 and the second flow detection device 44 to control the delivery of abrasive particles 33.

[0045] The processing fluid to be prepared is input into the test bench 10 through the original liquid conveying mechanism. After friction on the test bench 10, the mixed processing fluid is formed and then stored in the storage tank 35 of the closed storage system 17. The control terminal 19 receives data and controls the operation of the original liquid conveying mechanism and the storage tank 35, so that the processing fluid to be prepared and the mixed processing fluid re-enter the test bench 10 for friction mixing, realizing the cyclic preparation of the processing fluid. Through the design of the above structure, not only can the prepared processing fluid be stored separately, but also a small amount of the processing fluid to be prepared can be added to the mixed processing fluid for re-preparation to form a new processing fluid, or the mixed processing fluids between different storage tanks 35 can be cross-circulated to form a new processing fluid, meeting the proportioning requirements of more formulas. At the same time, the data of each formula can be collected in real time and stored in different storage tanks 35, which greatly reduces the cost of processing fluid preparation and improves the preparation accuracy.

The raw liquid conveying mechanism will input the liquid to be prepared into the liquid storage tank in the closed liquid storage system for storage until the liquid to be prepared in the liquid storage tank reaches the required liquid level. Then close the third valve and the fourth valve.

[0049] 2) Open the fifth valve at the outlet of the corresponding storage tank and / or the second valve connected to the raw liquid conveying mechanism through the control terminal. The liquid to be mixed in the storage tank is conveyed to the inlet valve through the main pipeline by the conveying pump.

The cavitation effect of the cavitation pump is used to eliminate bubbles. When it is not necessary to eliminate bubbles, the second outlet valve connected to the cavitation pump is closed, and the cavitation pump is turned off. The processing fluid enters the closed storage system through the first outlet valve. The outlet pressure detection device and outlet flow detection device on the main pipeline transmit the detected flow and pressure data to the control terminal.

[0052] 5) Waste liquid leaking from the test bench is treated by the abrasive concentration control system to recover the abrasive particles in the waste liquid.
