大型压铸机各种柱架结构性能比较
|
摘要
在传统机铰式压铸机柱架结构基础上,设计了二级液压缸顶出叠加行程结构,使顶出行程比此前增加了71%。提出了直锁式压铸机结构设计方案,液电混合动力柱架结构比液压单一动力柱架结构既缩短压铸生产循环时间,又节省了能源。直锁式柱架结构较机铰式柱架结构不仅能使开、锁模过程更加平稳,并有助于降低铸件飞边缺陷,也使压铸机总质量减少15%～20%。新的设计思路可为柱架结构设计提供借鉴。
Based on the conventional clamping unit on the die casting machine with the toggle clamp, the kicking stack travel structure with twice injection hydraulic pressure cylinder mechanism was designed, making the pushout stroke increased by 71%. In the article, the design scheme for the die casting machine with the categorical lock was provided. Compared with the clamping unit for fluid drive of the categorical lock, the clamping unit for fluid-electrical drive of the categorical lock can not only shorten the cycle time of die casting production,but also save the energy. Compared with the clamping unit on the die casting machine with the toggle clamp,the clamping unit on the die casting machine with the categorical lock not only makes the opening and locking moulds smoother, but also is conducive to reducing the casting defect of edge fins, furthermore, makes the total weight of the die casting machine decreased by 15%-20%. This new idea of design may provide reference for the design of other clamping units.
