摘要

为提高生产铝合金铸件的反重力铸造装备的实用性

减少重复投资

研制了多功能铝合金铸件反重力铸造装备。该装备主体采用上下罐结构

控制系统使用模糊化处理的积分分离PID算法作为控制方案

数字组合调节阀作为气路系统的执行机构。控制系统与装备主体相结合

可以实现低压铸造、差压铸造和调压铸造3种反重力铸造方法

提高了反重力铸造设备的实用性。

Abstract

In order to improve the performance operation for various aluminum castings

a multi-functional counter-gravity casting device for aluminum alloy was developed. Key structure of the device consists of two sealed-in jar

i. e. the upper jar and the nether one

in which fuzzy algorithm treated integral-separated PID is taken as control project of the control system

and combined valve controlled by digital signal is adopted as the executive unites of the pneumatic system. Three counter-gravity castings methods including low-pressure casting

differential-pressure casting and vacuum-assisted pressure casting can be accomplished by combining the control system with the main body of equipment

improving the practicability of the counter-gravity casting equipment.
