The present invention provides a case material sorting device, a control method and equipment, which relate to the technical field of paper sorting, and include: obtaining material information of case materials to be sorted; determining the required case box corresponding to the case materials to be sorted based on the material information; controlling the movement of a baffle assembly above the required case box to put the baffle assembly in a working state; controlling the movement of a sorting mechanism to transport the case materials to be sorted to a packing position of a packing mechanism; controlling the movement of a first driving member to transport the case materials to be sorted to the location of the required case box, so that the case materials to be sorted abut against the baffle assembly and then slide into the required case box; controlling the movement of the baffle assembly above the required case box to put the baffle assembly in a non-working state, so as to realize intelligent sorting and combination of printing materials and non-printing materials in units of cases, thereby improving efficiency and reducing costs.

A method for processing frameless shell materials, relating to the technical field of mobile terminal device shell processing, is provided and includes the following steps: S1 cutting a sheet material, S2 stamping and curling, S3 CNC processing, S4 grinding and cleaning, S5 surface T processing, and S6. nano-injection molding. The present disclosure adopts a stamping method and replaces traditional metal block CNC processing, which can reduce production costs. During the stamping process, the aluminum sheet is edge-curled and thickened to enhance the strength of the shell material. By cutting a step-shaped groove for screen installation, a frameless design is achieved, thereby reducing production costs and assembly procedures. The anodizing of the U-shaped frame surface allows the plastic to fully penetrate the aluminum shell surface, thereby enhancing integration and preventing plastic parts from falling off the U-shaped frame.

The invention discloses a design method of a Co-Cr-Ni-Ti-Al-V series eutectic high-entropy alloy with light weight and high temperature resistance performance. An aero-engine case is in an extreme working environment, the requirement for the performance of a workpiece material is harsh, and currently used nickel-based superalloy (such as Inconel 625 superalloy) is large in material density and does not meet the development target of the modern aviation industry. In recent years, development of the high-entropy alloy provides a direction for research and development of novel engine case materials, and meanwhile, the Co-Cr-Ni-Ti-Al-V series eutectic high-entropy alloy with light weight and high temperature resistance is designed in consideration of the problems of poor castability, high brittleness and the like of the alloy. According to the method in the claim 1, the density of the manufactured alloy ranges from 5.5 g / cm < 3 > to 6.8 g / cm < 3 > and is 19%-35% lower than the density of nickel-based high-temperature alloy (for example, the material density of Inconel 625 high-temperature alloy is 8.4 g / cm < 3 >). According to the method in the claim 1, the high-temperature mechanical property of the material is tested, it is found that continuous strengthening after yield is observed in the alloy manufactured within the service temperature range of the Inconel 625 nickel-based high-temperature alloy at 650-1100 DEG C, and the compressive strength exceeds 1000-1300 MPa; the compressive strength (for example, the compressive strength of Inconel 625 high-temperature alloy at the service temperature of 850 DEG C is about 700 MPa) of the nickel-based high-temperature alloy is 43%-86% higher than that of the nickel-based high-temperature alloy; no obvious crack is observed in the compressed sample. As the test temperature rises to 850-1300 DEG C (for example, the compressive strength of the Inconel 625 high-temperature alloy at the temperature of 1100 DEG C is about 400 MPa), the load on a stress-strain curve is reduced, and the strength is reduced to about 800-1000 MPa. According to the method in the claim 1, the high-temperature oxidation resistance of the material is tested, and after the material is oxidized for 200 hours at the temperature of 650-1100 DEG C, the thickness of an oxide layer of the manufactured alloy is measured to be about 3-5 microns and is 45%-67% lower than the thickness of an oxide layer of a nickel-based high-temperature alloy (for example, the thickness of an oxide layer measured after an Inconel 625 high-temperature alloy is oxidized for 200 hours at the temperature of 850 DEG C is measured to be about 9 microns). Compared with a nickel-based high-temperature alloy, the material designed by the invention has the advantages in material density, high-temperature mechanical property and high-temperature oxidation resistance, has a good development prospect in application materials of aero-engines, and also has very important reference value for subsequent design and application of eutectic high-entropy alloys.

The invention discloses a composite pump shell of a slurry pump and a preparation method and application of the composite pump shell, and belongs to the field of preparation of abrasion-resistant steel and iron materials. According to the invention, targeted composite structure design is carried out, and a high-wear-resistance ceramic hard phase is added into an easily-abraded area of the high-chromium cast iron pump shell by combining a two-step process of blank preparation and casting, so that a composite structure pump shell material and a component which are high in performance and long in service life are finally obtained. The proportion of the ceramic hard phase in the composite area of the pump shell exceeds 60%. The composite pump shell material has excellent anti-scouring and anti-abrasion capabilities, can be used for material conveying of slurry pumps in the fields of mines, dredging and the like, and has good application prospects and practical value.
