Quasi-constant-pressure pressurizing system of vibration forming machine

Abstract

The invention discloses a quasi-constant-pressure pressurization system of a vibration forming machine. The quasi-constant-pressure pressurization system comprises a bottom beam, a cross beam, a double-speed hydraulic system and four guide columns, the four guide columns are arranged on the bottom beam, the four guide columns are jointly connected with a heavy hammer in a sliding mode, the lower end of the cross beam is connected with a damper, and a displacement sensor is installed on the heavy hammer; and the damper and the displacement sensor are correspondingly arranged. According to the quasi-constant-pressure pressurization system, the pressurization force is set by setting a pressurization starting displacement L1 and a pressurization stopping displacement L2, so that the technical parameters such as the carbon block body density and the like are improved in cooperation with the vibration excitation force, and the purpose of rapid forming is achieved. The pressurizing process adopts a low-speed mild pressurizing and high-fitting carbon block forming process. Initial low-speed lifting is adopted, so that the carbon block slowly releases elasticity after compression molding, cracks of the carbon block are reduced, and the quality of the carbon block is improved.

Description

technical field [0001] The invention relates to the technical field of carbon block production in the carbon industry, in particular to a quasi-constant pressure pressurization system of a vibration forming machine. Background technique [0002] In recent years, with the development of science and technology and the progress of the times, electrolytic aluminum technology has made great progress, and the technical parameters such as volume density and bending resistance of prebaked anodes, which are consumables produced by electrolytic aluminum, are becoming higher and higher. The production of prebaked anodes is facing the problem of industrial upgrading, and the production efficiency and performance of the matching vibration molding machines need to be improved urgently. [0003] During the working process of the vibration forming machine, it is the heavy hammer that cooperates with the vibrating table to complete the vibration process. At present, most vibration forming ma...

AI Technical Summary

Problems solved by technology

[0003] During the working process of the vibration forming machine, it is the heavy hammer that cooperates with the vibrating table to complete the vibration process. At present, most vibration forming machines at home and abroad only use the heavy hammer form, and different exciting forces need to be adjusted for different raw materials and formulas during the production process. It is impossible to change the force of the hammer to adapt to the exciting force, resulting in low production efficiency, dense key technical indicators of products, poor flexural resistance, resistance and other indicators, especially in recent years. The quality of raw materials such as upstream petroleum coke has gradually declined, and electrolytic aluminum Manufacturers have gradually increased the quality requirements for prebaked anodes, and the existing single weight form can no longer meet the production requirements of prebaked anodes
