Technical Problem
[0003]现有的四柱压机在压制顶锤时，普遍存在以下不足，传统压机为单工位作业模式，一个完整的生产周期包括装料、合模、对中、压制、保压、卸压、开模、顶出等多个环节，其中压机巨大的活动横梁仅在压制、保压阶段做功，而在装料、取件等辅助操作过程中处于闲置状态，这种串行作业方式严重限制了设备的生产效率，成为产能提升的瓶颈
Benefits of technology
（1）本实用新型一种硬质合金顶锤压制成型的四柱压机，通过设置具有双工位的旋转工作台，并使旋转工作台通过升降旋转驱动单元实现双工位的切换，当压制工位正在执行压制与保压工序时，操作工位可同步进行顶出压坯、清理模具、喷涂脱模剂、装入新料等操作，使得压机的活动横梁在完成一次压制后，可立即对下一个已准备好的模具进行压制，提高了生产效率。
