侧向槽粉末制品压制成型工艺

摘要

叙述了YAN79Z-B型模架全自动干粉成型液压机压制工艺的设计，在压制粉末冶金侧向槽过程中，阴模与浮动冲上升到设定位置，送粉器前移对阴模腔内充满粉料后，上冲下行到阴模内向下压制时，利用阴模与浮动冲的同步浮动，压制到终了位置产品成型，然后阴模拉下，浮动冲微升推出产品，实现了侧向槽产品国产化，自动化生产。%The pressing process design of YAN79Z-B automatic powder hydraulic machine is discussed in this paper.In the process, while cavity block and floating punch rising to the set position, powder feeder filling the female mold cavity with pow-der, upper punch presses down to the cavity block, and the press is finished by using cavity block floating with the floating punch synchronously to the final position.Then cavity block moves down and floating punch moves up slightly to pull out the product, which achieves the localization and automate production of lateral grooves product.
