Extruding machine for steel claw protection semi-ring of electrolytic aluminum anode

Abstract

An extruding machine for a steel claw protection semi-ring of an electrolytic aluminum anode comprises a mounting support, an upper hydraulic cylinder, a lower hydraulic cylinder, a pressing block, anejection block and a forming base. A connecting plate is arranged on the mounting support and is provided with a receding notch, four upward sliding rods and four downward threaded rods. The formingbase is fixedly arranged on the lower end face of the connecting plate. A through hole vertically penetrating through the forming base is formed in the forming base. The cross sections of the throughhole, the pressing block and the ejection block are each in a semi-arc shape. A limiting plate and a lower hydraulic cylinder fixing plate are arranged on the four threaded rods in a sliding fit mode,and the height of the limiting plate is limited through a limiting nut. The ejection block is supported on the limiting plate, and the upper end of the ejection block extends into the through hole. The lower hydraulic cylinder is installed on the lower hydraulic cylinder fixing plate, and a piston rod of the lower hydraulic cylinder is connected with the ejection block. An upper hydraulic cylinder fixing plate is arranged between the four sliding rods, a sliding plate is arranged the four sliding rods in a sliding fit mode, and the pressing block is fixedly arranged on the lower end face of the sliding plate. The upper hydraulic cylinder is fixedly arranged on the upper hydraulic cylinder fixing plate, and a piston rod of the upper hydraulic cylinder extends downwards to be connected withthe sliding plate.

Description

Technical field [0001] The invention relates to the field of electrolytic aluminum equipment, in particular to an extruder with a half-ring protection for electrolytic aluminum anode steel claws. Background technique [0002] Modern electrolytic aluminum industrial production adopts cryolite-alumina molten salt electrolysis, molten cryolite is used as solvent, alumina is used as solute, carbon block is used as anode, and aluminum liquid is used as cathode. The anode of the electrolytic cell is composed of a carbon block, a steel claw, a steel-aluminum explosive welding block, and an aluminum conductive rod. The carbon block is fixed with the steel claw by phosphorus iron casting, and the steel claw and the steel-aluminum explosive welding block are used as steel- The steel is welded to form an anode carbon block with a T-shaped cross-section. The aluminum conductive rod and the explosive welding block of the anode carbon block are welded aluminum-aluminum to form a complete anode...

AI Technical Summary

Problems solved by technology

When a protective semi-ring with a specific height is required due to electrolytic cell parameters or production requirements, the mold can only be re-opened for processing, which is not conducive to reducing the production cost of electrolytic aluminum for manufacturers

In addition, the protective half-ring after molding is usually located in the lower mold cavity and needs to be taken out manually, which is time-consuming, laborious and inefficient, resulting in high labor intensity
