Abstract

The invention relates to the field of carbon materials, in particular to a vibration type carbon cold press forming device. In order to solve the technical problems that extrusion force applied to a carbon blank is limited, a large number of air holes exist in the extruded carbon blank, the tightness of the carbon blank is poor, and a high-density spiral carbon tube cannot be extruded. The vibration type carbon cold press forming device comprises a forming cylinder, a cold press forming unit and the like. The forming cylinder is connected with the cold press forming unit. When the extruding machine extrudes the carbon blank, the carbon blank extruded out of the forming cylinder is axially pressurized in a segmented mode, meanwhile, the exhaust pipe exhausts the carbon blank from the middle of the forming cylinder, the density of air holes in the carbon blank is reduced, vibration of the exhaust pipe is driven by vibration arranged on the movable baffle ring, and the carbon blank is extruded out of the forming cylinder. The distribution uniformity of the carbon blanks in the pressurizing treatment is improved, and the structural strength and the tensile property of the spiral carbon tube are improved.

Description

technical field [0001] The invention relates to the field of carbon materials, in particular to a vibration type carbon cold pressing forming device. Background technique [0002] Because carbon materials have good chemical stability, high temperature resistance, corrosion resistance and self-lubrication, low elastic modulus and good electrical conductivity, the structural strength and tensile properties of carbon materials are related to the pore size, Bulk density and elastic modulus are closely related. [0003] When producing tubular carbon materials, extruders are usually used to extrude segment by segment. Chinese patent CN209208026U provides a carbon spiral tube extrusion production equipment, which can continuously extrude spiral tubular carbon materials, And ensure that the raw materials are mixed evenly. However, when the extruder extrudes carbon blanks, it is necessary to ensure that the carbon tube has a complete thread structure, and to ensure that the raw mate...
