伴随现代科技水平的不停发展，对各个国家来说，金属资源变得越来越重要。在工业发展中，对金属资源的不合理使用以及过渡开采，浪费了大量的金属资源。金属资源的不断减少引起了人们的担忧，在此情况下，如何实现废弃金属的回收再利用，成了工业发展中尤为重要的课题。金属打包机就在这种形式下孕育而出。 打包机整体结构的设计，机座部分结构设计、材料选择，液压系统的设计、元件选择以及打包机液压原理图设计等是本次设计的主要内容。本次设计告别传统的丝杆传动，而采用液压传动的形式，为打包装置传递更大的工作压力。本次设计的打包机采用主、侧双液压缸进行工作，侧液压缸放在投放物料仓室的后方，主液压缸则放在投放物料仓室的侧方。压缩室的设计及其材料的选择是整体结构设计的主要内容。而活塞杆以及缸筒的计算校核等是液压缸设计的主要内容。在本次设计的打包机中，除去主、侧两个液压缸完成打包工作外，还包含有前门液压缸、上盖液压缸和锁紧液压缸，它们分别完成各自的工作，从而完成整个打包过程。 本次设计完成了上述液压金属打包机所需要的设计。整个液压金属打包机具有很大的优点，成本造价低廉，具有快速、高效的工作效率，应用广泛。 关键词：废金属的回收；金属打包机；液压 With the developme
