摘要
为了提升模具的承压能力并实现腔体大型化,提出了一种新型预应力钢丝缠绕凸面型腔体支撑环带硬质合金衬里的剖分式超高压模具结构。采用数值模拟方法对凹面型压缸、平面型压缸、凸面型压缸和支撑环带硬质合金衬里的凸面型压缸进行研究,分析了不同腔体结构对模具承压能力的影响。结果表明:凸面型结构可以有效降低压缸的剪切应力,但会导致支撑环的剪切应力略微升高。通过镶嵌硬质合金衬里,可以有效降低支撑环的剪切应力,降低材料成本。
In order to enhance the pressure-bearing capacity of the mold and achieve the large-scaleization of the cavity,a new type of pre-stressed steel wire wound cabochon cavity support ring with hard alloy lining in a split-type ultra-high pressure die structure is proposed.The concave type press cylinder,flat type press cylinder,cabochon press cylinder and cabochon press cylinder with hard alloy lining of support ring band are studied by numerical simulation method.The influence of different cavity structures on the pressure-bearing capacity of the die is analyzed.The results show that the cabochon structure can effectively reduce the shear stress of the pressure cylinder,but it will cause a slight increase in the shear stress of the supporting ring.By inlaying a hard alloy lining,the shear stress of the support ring can be effectively reduced,and the material cost can also be lowered.
