The utility model discloses a cross axle frame final forging die, including corresponding final forging upper die and final forging lower die, be equipped with final forging cavity between final forging upper die bottom surface and final forging lower die top surface, form final forging parting surface between final forging upper die bottom surface and final forging lower die top surface, the annular fly edge storehouse of final forging parting surface upper side is equipped around final forging cavity, the final forging convex column of four prism shape is equipped with in final forging cavity in final forging lower die, and final forging square ring cavity is final forging convex column outside in final forging cavity lower part, and one final forging cylindrical groove is equipped with in final forging cavity front side middle part and rear side middle part, and one triangle convex is equipped with in final forging convex column lower part's front side and rear side. The utility model can realize accurate positioning with the cooperation of the shallow square column hole of pre-forging piece and pre-forging convex column, so that metal material can be full in final forging cavity in the final forging process, and the final forging piece scrap rate is greatly reduced, and the final forging upper die and final forging lower die are balanced in stress when forging, and the service life of the die is long, and the die is convenient to demould after final forging.

The present application relates to the technical field of liquid chromatography column chiral stationary phase, in particular to a poria acid polysaccharide chiral stationary phase and application. The poria acid polysaccharide and its derivatives have spectral and high-efficiency chiral resolution capacity, and can realize effective resolution of chiral compounds in normal phase chromatography mode, so as to further obtain single configuration drugs, realize universal application of single configuration drugs, provide a new sugar-based stationary phase on the basis of traditional sugar-based stationary phases such as cellulose, amylose and beta-cyclodextrin, and enrich the range of chiral selectors. The chiral high-performance liquid chromatography column has the characteristics of fast separation speed, good resolution effect, good stability and repeated use.

This utility model discloses an automatic loading and unloading robotic arm structure for a glass double-sided straight-edge machine, relating to the technical field of glass double-sided straight-edge machines. It includes a base assembly and a robotic arm assembly. A movable turntable assembly is connected to the middle of the base assembly, and the robotic arm assembly is mounted on the top surface of the movable turntable assembly. A material-grabbing component is connected and installed at the end of the robotic arm assembly away from the movable turntable assembly. This automatic loading and unloading robotic arm structure for a glass double-sided straight-edge machine, by incorporating the robotic arm assembly and the movable turntable assembly, maximizes the overall structural flexibility of the device. This ensures that the material-grabbing component can perform fast and stable loading and unloading operations on the glass material. The structural design of the material-grabbing component ensures stability during the loading and unloading process. The base assembly drives the movable turntable assembly, which is connected to the robotic arm assembly and the material-grabbing component, to perform stable horizontal movement.
