The application discloses a diamond wire drawing tower wheel and particularly relates to the field of intelligent equipment for diamond wire forming processing. The diamond wire drawing tower wheel comprises a mounting seat, the side of the mounting seat is provided with a self-rotating tower wheel body, the tower wheel body is in the shape of a circular truncated cone, a plurality of annular grooves one are formed in the outer side of the tower wheel body, and the diameters of the annular grooves one gradually increase; the drawing tower wheel further comprises a cleaning device arranged above the tower wheel body, the cleaning device comprises a mounting plate fixedly connected with the mounting seat, a plurality of connecting rods one rotatably mounted on the mounting plate, and the connecting rods one are in one-to-one correspondence with the annular grooves one. By arranging the cleaning device at the position where the diamond wire penetrates into the annular grooves one, the metal scraps on the surface of the diamond wire can be cleaned, and the metal scraps can be prevented from entering the annular grooves one along with the diamond wire, so that the metal scraps are prevented from being pressed into the surface of the diamond wire or from being rubbed against the surface of the diamond wire at the position where the diamond wire and the annular grooves one are in extrusion contact.

This invention discloses a metal surface rust inhibitor, comprising the following raw materials by mass percentage: deionized water: 80%–90%; organic polyol amine corrosion inhibitor: 6%–16%; heterocyclic high-efficiency corrosion inhibitor: 0.5%–3%; water-based film-forming agent: 2%–7%; nonionic low-foaming surfactant: 0.2%–1.5%; pH adjuster: 0.3%–1.5%; defoamer: 0.05%–0.3%. This invention is completely non-toxic and environmentally friendly, free of nitrites, chromium, nickel, phosphorus, and heavy metals, meeting environmental emission standards. It has a low odor, is easy to clean, non-greasy, and does not affect coating, phosphating, or assembly. It provides long-lasting rust prevention, forms a dense film with strong adhesion, significantly extends the rust prevention period, and is suitable for multiple metals, exhibiting no corrosion to carbon steel, cast iron, galvanized steel, and stainless steel. It has excellent rust prevention performance, is easy to apply, and can be applied by immersion, spraying, or brushing at room temperature, with fast drying.

The utility model discloses a stop valve, including valve body, valve core and valve rod, the top of valve body is provided with the detachable connection of valve cover, one end of valve rod is connected with valve core, and the other end passes through valve cover and is provided with hand wheel in end portion, valve rod is connected with valve cover thread, the middle part of valve cover has the through slot, be provided with oil tank in the through slot, valve rod passes through oil tank and is connected with its screw thread, the oil tank has the oil storage cavity for oil storage in, the inner wall of through slot has the limiting piece detachable connection with oil tank, through the design of oil tank, the thread section of each area of the surface of valve rod in the lifting process will pass through oil tank and be infiltrated by internal oil, can play good antirust and lubrication effect, even if long -term use valve rod rotation process still can keep good smoothness, thereby ensure the labor -saving of operating hand wheel.

This application discloses a method and system for preparing aged oil-based water-based metal cutting fluid based on machine learning, comprising: obtaining stability characterization parameters of aged oil for stability classification and determining pretreatment parameters; sequentially performing preheating and dilution, ultrasonic treatment, electrostatic coalescence, centrifugal separation and solid-liquid separation to obtain a base oil for the cutting fluid; using the obtained base oil as the oil phase, compounding it with emulsifier, oiliness agent, extreme pressure anti-wear agent, rust inhibitor, pH stabilizer, bactericide and defoamer to construct a formulation sample and collect performance and cost data; using the formulation sample to train a wavelet neural network to establish a formulation-performance mapping model; using simulated annealing-particle swarm optimization algorithm to obtain the target formulation; preparing aged oil-based water-based metal cutting fluid according to the target formulation and verifying it; this method realizes the high-value resource utilization of aged oil, effectively demulsifies and dehydrates through multi-stage synergistic treatment, and efficiently obtains the globally optimal formulation by combining machine learning algorithms. The resulting cutting fluid has cooling, rust prevention, lubrication and cleaning properties, reducing production costs and reducing environmental pollution.
