Pressing sintering apparatus of spherical graphite

Abstract

The invention discloses a pressing sintering apparatus of spherical graphite. The pressing sintering apparatus comprises a sintering furnace body, clamping blocks, a hydraulic pump and a spherical mold, wherein the bottom of the spherical mold is a bottom annular plate, the top of the spherical mold is a top annular plate, annular plates are uniformly arranged between the bottom annular plate andthe top annular plate, the spherical mold is fixed on the inner bottom end surface of the sintering furnace body by virtue of four clamping blocks in a clamping manner, the clamping blocks are connected by virtue of an adjusting screw, the outer end of the adjusting screw is fixedly provided with an adjusting wheel, the upper end surface of the sintering furnace body is fixedly provided with a hydraulic cylinder, the bottom end surface of the hydraulic cylinder extends out to form a hydraulic sleeve rod, a hydraulic sliding rod is installed inside the hydraulic sleeve rod in a sliding manner,the bottom of the hydraulic sliding rod is detachably fixedly provided with a pressing plate by virtue of a bolt, the hydraulic pump is communicated with the hydraulic cylinder by virtue of an oil inlet pipe and an oil return pipe, and the hydraulic pump is fixed by virtue of a supporting rod and the sintering furnace body. The pressing sintering apparatus can perform the uniform and sufficient pressing work in the sintering process of a spherical graphite finished product, and the finished product spherical graphite is more stable in structure.

Description

technical field [0001] The invention relates to the technical field of graphite production and processing, in particular to a pressing and sintering device for spherical graphite bodies. Background technique [0002] Graphite is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb pattern) to form a covalent molecule. Graphite materials are widely used in metallurgy, chemical industry, machinery, medical equipment, nuclear energy, automobile, aerospace and other industries. [0003] When graphite is actually applied, it will appear as a fixed-shaped finished product, such as block shape, ring shape, etc. Graphite finished products of different shapes can be made by sintering. If it is not firm and the stability of the internal structure is poor, since the surface of the spherical object is round and curved, the actual pressing will have a low degree of uniformity and difficu...
