Carbon electrode horizontal type bidirectional vibration molding technique and special forming equipment

Abstract

The invention relates to a horizontal two-way vibration forming process of carbon electrode and special forming equipment. The forming process comprises following steps: selecting materials, heating, mixing, kneading, air-drying, adding materials, pre-vibrating, pressurizing, two-way vibrating, and de-molding. The special forming equipment consists of a four-axis amplitude modulation vibration table, a frame, a mold, a pressure-bearing conductive connector, a hydraulic piston, a vibration energy-storage spring, a hydraulic mechanism, etc., wherein the mold consists of an upper mold, a middle mold and a lower mold; a vibration motor is fixed on the upper mold; the upper mold, the pressure-bearing conductive connector and the hydraulic piston on the hydraulic mechanism constitute a pressure conductive device and are fixed on the frame through the two-way vibration energy-storage spring; the lower mold is horizontally fixed on the four-axis amplitude modulation vibration table through a flip hinge; and the middle mold is below the upper mold and above the lower mold. Carbon electrode manufactured by the process has the advantages of high strength and density, good consistency, less internal defects, high forming efficiency, and reduced energy consumption.

Description

technical field [0001] The invention relates to a carbon electrode production process and its special equipment, in particular to a carbon electrode horizontal two-way vibration forming process and its special forming equipment. Background technique [0002] At present, the molding of carbon electrodes is a vertical vibration molding process. When vibration is applied, the mold is placed upright on the vibration table, and the hydraulic press pressurizes the raw materials in the mold from top to bottom. When producing longer specifications of carbon electrodes, The exciting force is difficult to spread evenly, resulting in uneven pressure and inconsistent density inside the green electrode body, resulting in defects in the produced products, a high scrap rate, and a high rate of electrode breakage during the user's use. Chinese Patent Publication No. CN1571593, published on January 26, 2005, the name of the invention is a production process of a carbon electrode containing f...
