The invention relates to bar material forging machining method of titanium alloy, particularly to a forging machining method of large-sized bar materials of TC4 (Ti-6Al-4V) titanium alloy. The forging machining method is characterized by comprising the following steps of step 1, performing cogging forging, step 2, performing intermediate forging above a phase transformation point, step 3, performing intermediate forging below the phase transformation point, step 4 and step 5, performing finished product forging and obtaining the phi 200 to 300 mm and 2000 to 3000 mm length of large-sized bar materials of the TC4 titanium alloy finally. Compared with the prior art, a large-sized ingot casting and a large-tonnage forging device are not required and the industrialized production can be achieved through an ordinary industrial 3 ton ingot and a small-tonnage forging press and the equipment investment is small, only a 3 tons of electric arc furnace and a 3000 tons of forming oil press which is matched with the electric arc furnace need to be invested in the phi 600 of 3 ton ingot, the small-tonnage forging press such as a 1600 tons of forging press needs to be invested in the forging process, and accordingly the equipment investment is significantly reduced.

The present application provides an image acquiring device and a method of correcting coordinates of the image acquiring device, wherein the method includes: detecting a coordinate of a defect detected in a process; initializing a position of a photographing device according to the coordinate of the defect detected in a preprocessing; then adjusting the position of the photographing device according to a position of the defect in the picture currently captured by the photographing device, so that the defect is located at the center of the picture currently captured by the photographing device; recording the coordinate of the defect at the center of the picture; and providing the coordinate of the defect at the center of the picture to a data management system.

The invention discloses a processing method of instant vacuum dried penaeus aztecus. The method mainly comprises the following steps of (1) material selection, (2) cleaning, (3) water boiling, (4) vacuum pickling, (5) vacuum critical low-temperature drying and (6) sealing package. The penaeus aztecus is used as the raw materials, the vacuum pickling and the vacuum critical low-temperature drying are adopted, the vacuum pickling conditions include the vacuum degree being 70000Pa to 85000Pa and the pickling time being 5.5 hours to 6 hours, the vacuum critical low-temperature drying condition includes the vacuum degree being 200Pa to 400Pa, the heating is not needed in the initial period, the penaeus aztecus is subjected to temperature reduction and dewatering natural drying under the vacuum effect, the drying time is 0.8 to 1 hour; in the middle period stage, the temperature of a drying machine is regulated to 65 to 70 DEG C, and the state is maintained for drying for 6.5 hours to 7hours; and finally, the temperature of the drying machine is regulated to 45 DEG C to 50 DEG C, and the state is maintained for drying for 1.5 hours to 2 hours. The process has the advantages that the penaeus aztecus browning, oxidation browning and high-temperature Maillard reaction browning can be effectively prevented, the active ingredient content and the color of the dried penaeus aztecus are perfectly maintained, the hardness is proper, the chewy effect is realized, and better popularization and application values are realized.

The invention relates to the technical field of antibiotic production, in particular to a daptomycin extraction method. The method includes the following steps of firstly, filtering daptomycin fermentation liquor through a ceramic film; secondly, making filtered liquor pass through large-pore adsorption resin so that eluant can be collected; thirdly, mixing NM-Q anion exchange resin with the obtained eluant, and collecting eluant; fourthly, making the eluant obtained in the third step pass through a reverse phase silica gel MNsil-C18 column, conducting gradient elution on the column through an ammonium acetate ethanol solution, and collecting eluant; fifthly, concentrating the daptomycin eluant obtained in the fourth step, adding calcium acetate and isopropyl alcohol, and conducting standing, crystallization, suction filtration and drying to obtain daptomycin crystallization powder. The method has the advantages that the virulent acetonitrile solution is not used as the eluant, pressure on the environment and health of production personnel is reduced, the use of acid-base regulator is reduced, and the production cost is reduced.
