Graphite vacuum double-sided floating pressing forming system

Abstract

The invention relates to a graphite vacuum double-face floating pressing forming system which comprises a pressing frame, a lower pressing rod, a lower pressing die, a die sleeve, an upper pressing rod and an upper pressing die, the lower pressing rod is vertically and fixedly arranged on the lower portion of the pressing frame, the lower pressing die is arranged at the upper end of the lower pressing rod, and the die sleeve is longitudinally and slidably arranged in the middle of the pressing frame. A vertical die cavity is formed in the middle of the die sleeve, the upper pressing rod is longitudinally arranged on the upper portion of the pressing frame in a sliding mode, the upper pressing die is arranged at the lower end of the upper pressing rod, a plurality of vertical small holes are formed in the lower pressing die, a pipeline is arranged in the lower pressing rod, one end of the pipeline is communicated to the lower pressing die, and the other end of the pipeline is communicated to the vacuum pump. The invention aims to solve or at least alleviate the problems that the product performance of a special graphite technology is not easy to exert, the product yield is low and the production period is relatively long in the existing graphite material pressing and forming process, and provides a graphite vacuum double-sided floating pressing and forming system.

Description

technical field [0001] The invention relates to the technical field of graphite materials and powder metallurgy, in particular to a compression forming system for graphite vacuum double-sided floating. Background technique [0002] Graphite is an important non-metallic mineral resource. It has high temperature resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, self-lubricating, thermal conductivity, and electrical conductivity. It is widely used in metallurgy, machinery, electronics, chemical industry, and light industry. , military industry, national defense, aerospace and refractory industries. [0003] Improving product yield and product quality has always been the focus of research in the field of special graphite. Compression forming is an important process in the production process of graphite materials, and the quality of this process affects the final quality of graphite materials. The existing pressing and forming process pr...
