This invention relates to the field of automotive air conditioning manufacturing technology, and discloses an automotive air conditioning pipe crimping equipment, comprising a feeding device, a processing device, and a unloading device. The processing device includes end leveling, upsetting, radial extrusion, and deburring units, as well as a three-axis transfer claw. The unloading device integrates unloading and visual inspection units. The equipment achieves multi-process automatic flow of pipe fittings through the three-axis transfer claw, sequentially completing pipe end leveling, upsetting, radial extrusion forming, and deburring, ensuring processing coaxiality, avoiding pipe eccentricity and cracking, and improving pipe end forming accuracy and sealing performance. Simultaneously, online quality inspection through visual inspection during the unloading stage automatically identifies defective products. The entire machine integrates feeding, multi-process forming and finishing, online inspection, and automatic unloading, achieving a high degree of automation, reducing labor intensity, and improving production efficiency and product yield.

This invention discloses a coating composite structure and a coating device. The composite structure includes at least a first structural component, a second structural component, and a third structural component. The first and second structural components are assembled to form a coating head liquid outlet, and the third structural component is assembled to form an air knife outlet. The second structural component is positioned between the first and third structural components. The coating head liquid outlet and the air knife outlet are located on the same side of the coating composite structure. The integration of coating and drying core functions is achieved through the coordinated installation of the first, second, and third structural components, replacing the independent components and support designs of the coating head and air knife in traditional coating equipment. This makes the coating and drying process flow structure more compact and significantly reduces the distance between the coating head liquid outlet and the air knife outlet, allowing for a closer connection between the perovskite solution coating and air curtain drying processes.

This invention discloses an automatic multi-station wire mesh welding processing equipment, including a frame and a welding mechanism mounted on the frame. It also includes: a first frame mounted on the frame and a second frame fixedly mounted on the first frame. The frame is connected to the first frame via a drive component. When the drive component operates, it moves the first and second frames along a preset path. A mounting base is fixedly mounted on the bottom wall of the first frame. This invention uses a dual-axis guide rail to drive the frame for precise displacement. Combined with crisscrossing adjustable fixing plates and elastic magnetic clamping components, it achieves multi-station synchronous positioning and stable clamping of wire mesh of different specifications, avoiding welding offset and deformation. Relying on an electromagnetic lifting drive and spring reset structure, it completes automatic alignment, welding, and unloading closed-loop operations, significantly reducing manual intervention, improving processing accuracy and production efficiency. The equipment is highly versatile and adaptable to the needs of large-scale continuous production.

This invention relates to a high-purity, high-toughness, low-temperature stainless steel and its smelting and preparation methods, belonging to the field of stainless steel metallurgical technology. The smelting method includes electric furnace smelting, refining, vacuum oxygen blowing decarburization, vacuum degassing, and vacuum consumable remelting; the stainless steel ingot contains P≤0.01%, S≤0.001%, and O≤0.0005%. The method employs a synergistic smelting process involving electric furnace, refining, VOD, VD, and VAR, with close integration of each process and reasonable parameter matching, achieving the ultimate removal of P, S, and O. The purity is significantly higher than existing technologies, solving the technical problem of achieving coordinated ultimate removal of S and O in existing processes.

The application discloses a standardized brewing method of sweet potato dregs and baijiu vinegar, and relates to the technical field of fermented food processing.The application comprises the following steps: selecting fresh sweet potatoes and indica rice; washing and peeling the sweet potatoes, then soaking and sterilizing the sweet potatoes with salt water, and crushing the sweet potatoes to obtain sweet potato fragments; washing and soaking the indica rice, and cooking the indica rice until it is fully cooked without white core, and then cooling the indica rice to obtain matured rice; mixing the sweet potato fragments and the matured rice, adding mixed brewing yeast, uniformly stirring, and then sealing the mixture into a fermentation tank to perform alcohol fermentation; when the alcohol content reaches 6-8% and the pH value decreases to 4.0-4.5, adding compound acetic acid bacteria to the material after the completion of the alcohol fermentation, and performing fermentation for 15-20 days until the total acid content is greater than or equal to 4.5 g / 100 mL and the pH value is stable at 3.2-3.8; and adding spice extract liquid to the acetic acid fermentation liquid to age for 30 days.The application can improve the release efficiency of sweet potato flavor substances, shorten the fermentation period and enhance the product quality stability through accurate pretreatment of the sweet potatoes, synergistic fermentation of compound strains and segmented control of fermentation parameters.
