摘要
介绍了一种新型的双斜边扇形块式多层交错剖分超高压模具,这种超高压模具是由箍紧环、多层交错剖分的预紧环和双斜边扇形组合压缸3部分构成。分析了双斜边扇形块式多层交错剖分超高压模具的受力情况,并与年轮式超高压模具做对比。结果表明:在相同腔体压力的情况下,双斜边扇形块压缸的等效应力和最大切应力分别降低46.8%和50.9%;双斜边扇形块压缸破坏时的油压为年轮式整体压缸油压的1.78倍;新型多层交错剖分超高压模具可实现大腔体超高压模具的制造,且具有装配方便、维修简单的特点。
This paper introduces a novel ultra-high pressure device,double-beveled multilayer stagger-split die.This device consists of a double-beveled sector block cylinder,a discrete prestressed ring and a hoop ring.We explored the force situation of the double-beveled multilayer stagger-split die,and the results were compared with those of the belt type die.The results show that the von Mises stress and maximum shear stress of the double-beveled multilayer stagger-split die is 46.8%and 50.9%lower than that of the belt type die.The experimental results show that the pressure of the double-beveled multilayer stagger-split die is about 78%higher than that of the belt type die.At last,the double-beveled multilayer stagger-split die is easy to manufacture and assemble,and can achieve large cavity mold manufacturing.
