Manufacturing method of loading auxiliary tool for production of submerged aluminum carbohydrate port

The utility model relates to production equipment of an aluminum carbohydrate port, in particular to a loading aid for the production of a submerged aluminum carbohydrate port.
Background technology:
Immersion-type aluminum carbide port is a kind of product commonly used in multi-furnace continuous casting, which is suitable for the casting of various alloy steels. The process requirements for preparing aluminum-carbon submerged entry nozzles are extremely stringent. The main raw materials are fused corundum and flake graphite. In order to improve the performance of the products, a small amount of silicon carbide powder needs to be added. Generally, phenolic resin is used as binder, and then isostatic pressing is carried out after granulation and other processes.
3. In the preparation process of aluminum carbon mouth, it is necessary to add the granulated raw materials to other raw materials, put them into the nozzle mold and perform static pressure. The mold includes a core and a shell. Due to the overall length of the mold and the narrow entrance of the cavity, in order to ensure the product quality during static pressure, it is necessary to continuously tamper the raw materials loaded into the mold (I. e., part of the raw materials are loaded and steel bars are used for tamping). The filling of the existing nozzle mold generally adopts pure manual work. The operator needs to bend down many times to take objects while filling the filler, which is extremely intensive and is not conducive to human health.
Technical realization elements:
4. In view of the problems raised in the background technology, the purpose of this utility model is to provide a submerged aluminum carbon mouth production loading auxiliary tool. The auxiliary tool adopts a special guide rod for hydraulic lifting, cooperates with a positioning hole, and adopts positioning for the nozzle mold. Clamping, in the tamping process, does not require workers to bend down, in addition, the tamping efficiency is high, the effect is good, and the production efficiency can be effectively improved.
5. In order to achieve the above purpose, the utility model adopts the following technical scheme:
6. A loading aid for immersion aluminum carbon mouth production, comprising a platform, a positioning fixture, a lifting arm and a guide rod. The fixture is composed of a base, a fixed half ring, and a movable half ring. The base is arranged in the middle of the upper surface of the platform. One side of the base is provided with a semicircular positioning groove with vertical axial direction. The fixed half ring is arranged on the upper part of the positioning groove and is coaxial with the positioning groove, and the movable half ring; A support seat is provided on one side of the platform, a hydraulic cylinder is provided on the support seat, a lifting arm is provided at the piston rod end of the hydraulic cylinder, and a vertical guide hole is provided at the other end of the lifting arm. The guide hole is coaxial with the positioning groove, the guide rod can be positioned through the guide hole, the guide rod is a hollow guide rod, and an annular boss is provided on the circumference of the lower end.
The side wall of the guide hole is provided with a threaded through hole, and a hand screw is arranged in the threaded through hole for loosening or fixing the guide rod.
The guide rod is a vertical straight tubular structure as a whole, and its inner pipe diameter is clearance fit with the core of the nozzle die.
9. One side of the fixed half-ring is hinged with the movable half-ring through a hinge, a positioning member is arranged on the outer wall of the other side of the fixed half-ring, and a hook is arranged on the movable half-ring and connected with the positioning member through the hook.
The base is fixedly connected with the platform by bolts, and the side surface of the open end of the fixed half ring is flush with the two ends of the positioning groove of the base.
11. The beneficial effects of the utility model are: the end face of the guide rod of the utility model is designed with an annular boss suitable for the nozzle mold cavity, which is convenient for uniform tamping of raw materials. The coaxial positioning fixture and the guide hole make the guide rod Can be up and down in the guide hole
Mobile, easy to use gravity to tamping raw materials, reducing labor intensity; At the same time, the guide rod can be fixed in the guide hole, no temporary search, no need to bend down to take; Hydraulic lifting is suitable for different height ranges and has high versatility.
