Abstract
Description
Technical Field
[0001] This utility model relates to the field of proportioning mechanism technology, specifically to an automatic cutting fluid proportioning mechanism. Background Technology
[0002] In metal cutting processes, cutting fluid plays a crucial role. It not only lowers the temperature of the cutting zone through cooling, preventing tool overheating and workpiece deformation, but also lubricates the surface, reducing friction between the tool and workpiece, extending tool life, and improving the surface finish of the machined material. Furthermore, cutting fluid removes debris and impurities generated during cutting, keeping the machining area clean, and also provides some rust prevention, protecting the machined workpiece from corrosion. Therefore, the proper formulation and use of cutting fluid are indispensable for ensuring machining quality and improving production efficiency.
[0003] However, traditional cutting fluid mixing methods rely heavily on manual operation, which has several drawbacks. First, manual mixing cannot guarantee accuracy in every batch, as human factors such as operator skill and concentration can affect the results. Inaccurate mixing not only affects machining quality but can also damage equipment and increase production costs. Second, manual mixing is inefficient, especially in large-scale, high-intensity production environments, where manual operation struggles to meet the demands for rapid and accurate mixing, thus limiting the potential for increased production efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 1-4As shown, this utility model provides an automatic cutting fluid mixing mechanism that can automatically and accurately mix pure water and stock solution to generate cutting oil that meets the requirements. It also has functions such as concentration detection, liquid level monitoring, and mixed liquid circulation and transportation, which significantly improves the mixing efficiency and accuracy.
[0029] The main structure of this automatic cutting fluid mixing and supply mechanism includes a container body 1, which is internally divided into a pure water chamber 101, a raw fluid chamber 102, and a mixing chamber 103. The pure water chamber 101 stores pure water, the raw fluid chamber 102 stores the cutting fluid stock, and the mixing chamber 103 mixes the pure water and the stock. The outer side of the container body 1 has corresponding interfaces and pipelines for easy connection of the various modules. Additionally, a raw fluid pump 10 is located on the outer side of the container body 1, with its output end connected to the top of the raw fluid chamber 102 for injecting new cutting fluid stock into the chamber.
[0030] To achieve better mixing, a mixing module 2 for mixing pure water and stock solution, a detection module 3 for detecting the concentration of the mixed solution, and a control unit 4 are respectively installed on the outside of the container body 1.
[0031] The proportioning module 2 consists of a proportioner 201, a proportioning pump 202, an electronic flow control valve 203, and a first metering device 204. When connected, the two input terminals of the proportioner 201 are connected to the pure water chamber 101 and the raw liquid chamber 102 respectively via pipelines. The pure water chamber 101 is equipped with a first liquid pump 205 to provide power. A manual control valve 206 is installed on the pipeline from the raw liquid chamber 102 to the proportioner 201, allowing the operator to manually adjust the raw liquid flow rate as needed. The output terminal of the proportioner 201 is connected to the proportioning chamber 103 to achieve preliminary mixing of pure water and raw liquid. The proportioning pump 202 is used to pump the raw liquid directly from the raw liquid chamber 102 into the proportioning chamber 103. Its output pipeline is sequentially equipped with an electronic flow control valve 203 and a first metering device 204 to achieve precise flow control and metering.
[0032] The detection module 3 consists of a concentration detector 301 and a second liquid pump 302. When connected, the input end of the concentration detector 301 is connected to the bottom of the mixing chamber 103 through a pipeline, and the second liquid pump 302 drives the mixed liquid into the concentration detector 301 for detection. The output end of the concentration detector 301 returns to the top of the mixing chamber 103 through a pipeline, forming a closed-loop detection circuit.
[0033] The control unit 4 is communicatively connected to the concentration detector 301 and the electronic flow control valve 203. During the mixing process, the control unit 4 automatically adjusts the discharge rate of the electronic flow control valve 203 based on the signal fed back by the concentration detector 301 to accurately adjust the content of the original liquid in the mixture until the concentration detected by the concentration detector 301 meets the standard, thus ensuring the mixing accuracy.
[0034] It should be further explained that a storage chamber 104 is added inside the container body 1 to store the prepared cutting oil for later discharge and use. This chamber is isolated from the mixing chamber 103 to reduce the impact on the mixing ratio during use. A third liquid pump 5 is added outside the container body 1, with its input end connected to the mixing chamber 103 and its output end connected to the storage chamber 104, to realize the transfer of the mixed liquid after the mixing is completed.
[0035] A delivery module 6 is provided on the outside of the container body 1 for conveying the mixture in the storage chamber 104. The delivery module 6 includes several fourth liquid pumps 601. The input end of each fourth liquid pump 601 is connected to the storage chamber 104, and the output end is connected to the discharge pipe 602. A second metering device 603 is installed on the discharge pipe 602 to measure the amount of cutting oil output. A return pipe 604 is also provided between the output end of the fourth liquid pump 601 and the discharge pipe 602, allowing the cutting oil to flow back to the storage chamber 104 when needed, increasing flexibility.
[0036] The container body 1 is equipped with a water level detector 7 at the top, which extends into the pure water chamber 101, the stock solution chamber 102, the mixing chamber 103, and the storage chamber 104 respectively. This detector monitors the liquid level in each chamber in real time and sends the data to the control unit 4 for timely liquid replenishment or other measures. Simultaneously, the container body 1 contains aerators 8 located inside the mixing chamber 103 and the storage chamber 104, powered by an electrical box 9 at the top of the container. These aerators improve the uniformity and stability of the mixture. Furthermore, continuous aeration ensures the quality of the mixed cutting oil, preventing any impact on its subsequent use.
[0037] During operation, the control unit 4 starts the first liquid pump 205 according to the preset mixing ratio. At this time, pure water and the original liquid enter the mixing unit 201 and the mixing chamber 103 in the set ratio for mixing. After mixing, the concentration detector 301 detects the concentration of the mixture and adjusts the electronic flow control valve 203 according to the detection result until the predetermined concentration is reached. After mixing, the third liquid pump 5 transfers the mixed cutting oil to the storage chamber 104. When needed, the cutting oil is output to the point of use through the delivery module 6.
[0038] In summary, the automatic cutting fluid mixing mechanism provided by this technical solution can perform mixing operations according to a preset ratio through the mixing module 2. In addition, combined with the detection module 3 and the control unit 4, the control unit 4 can accurately adjust the discharge rate of the original fluid according to the concentration of the mixed fluid until the predetermined concentration is reached. The entire process automatically and accurately mixes pure water and original fluid, improving the mixing efficiency and accuracy.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
