The invention discloses an automatic loading and unloading device and method applied to grabbing cemented carbide tools, comprising a frame and a first tray module, a second tray module, and tray transfer module, the first planetary disk module, the second planetary disk module, the planetary disk transfer module, the tool transfer module, the push module and the transfer module. Through visual positioning technology, Internet of Things, intelligent robots, automation devices and supporting tooling, the automatic loading and unloading equipment can automatically identify the specifications of CNC carbide cutting tools, automatically select the corresponding loading and unloading process, and realize different types of carbide cutting tools in the tray and The automatic loading and unloading between planetary discs eliminates the impact of manual contact on product quality, greatly improves labor productivity, reduces labor requirements by 30% to 50%, and greatly reduces the labor intensity of operators, reducing costs and increasing efficiency significantly.

The invention relates to the technical field of nuclear power maintenance, and specifically discloses a nuclear power plant horizontal multi-stage centrifugal pump core package disassembly tool and method. The support base and the bottom plate are parallel to each other; when disassembling the core package, slowly lift the pump core package and place it on the disassembly tool stably, so that the outer edge of the pump core package is clamped on the upper support ring, and then the subsequent disassembly operation is completed . The invention greatly liberates manpower, makes on-site core package disassembly and rotor displacement measurement work simple and efficient, reduces the risk of equipment damage, and reduces the safety risk.

A fully automatic mold opening method and mold structure for a conical rubber spring vulcanization mold. The rubber injection insert of the vulcanization mold is fixed on the middle mold of the mold and moves up and down together with the middle mold to complete the connection between the mold rubber injection cylinder and the vulcanized product. The automatic separation between the molds realizes the automatic operation of the injection inserts; the guide mechanism is set between the middle mold, the valve mold and the lower mold of the vulcanization mold so that the valve mold moves up and down with the middle mold to complete the gap between the two valve molds. The separation and closing of the vulcanization mold can realize the automatic separation between the valve mold and the vulcanized product; the vulcanized product is automatically ejected by setting an ejection mechanism on the lower mold of the vulcanization mold; the bottom mold of the vulcanization mold and the lower plate of the curing equipment The fast positioning between the vulcanization mold and the vulcanization equipment is realized by setting a positioning mechanism between them. The invention realizes the automatic separation between the mold parts and between the mold parts and the vulcanized product, and avoids the highly difficult semi-automatic operation and structure of using the mobile crane back and forth.

The invention relates to a multifunctional built-in hanging arm which is a strip profile, wherein a bevel edge is arranged on the section of the profile; a first flange extends out of the low end of the bevel edge; a second flange extends out of the middle part of the bevel edge; the tail end of the first flange is fixedly connected with the tail end of the second flange by a first C-shaped groove; a third flange extends out, close to the high end, of the bevel edge; a fourth flange extends out of a connecting part between the middle part of the bevel edge and the second flange; the middle upper part of the third flange is intersected with the middle part of the fourth flange; a fifth flange extends out of the tail end of the fourth flange; the tail end of the third flange is fixedly connected with the tail end of the fifth flange by a second C-shaped groove; the hanging arm further comprises a horizontal sixth flange; at least two third C-shaped grooves are formed on the lower side of the sixth flange; openings of the first C-shaped groove, the second C-shaped groove and the third C-shaped grooves are vertically downward; the third C-shaped grooves are higher than the second C-shaped groove; and the second C-shaped groove is higher than the first C-shaped groove. The hanging arm can mount various built-in components at the top of a coach simultaneously, is high in integration level, improves the mounting efficiency and reduces the weight of the coach.

The invention provides a strengthened and stable yttrium oxide slurry and a preparation method thereof. The slurry comprises the following components in parts by weight: 10-15 parts of yttrium oxide glue; 3-8 parts of organic latex; 3-8 parts of deionized water ; 70-80 parts of yttrium oxide powder, 1-5 parts of stabilizer, 0.03-0.05 part of wetting agent; 0.03-0.05 part of defoamer; the stabilizer is zirconia and / or alumina powder. The present invention successfully improves the stability of the slurry by adding a stabilizer to the yttrium sol + yttrium oxide powder slurry with the highest inertness and worst stability, and improves the bonding strength of the slurry by adding an organic adhesive. In this way, a yttrium oxide slurry with high strength and stable performance is prepared, and a high-quality yttrium oxide surface layer mold shell with a smooth and complete inner surface is further obtained, which is used for investment precision casting of titanium alloys, high-temperature alloys, and zirconium alloys.
