分段式阶梯型挤压杆的设计

Design of Sectional Stepped Extrusion Rod

锆合金挤压杆的工作条件非常恶劣,要承受巨大的、周期性变化的挤压应力,对其结构与强度提出了很高的要求。针对某种小规格锆合金挤压工艺,分析了常规设计的挤压杆的不足,并特别设计了一种分段式阶梯型挤压杆。该挤压杆具有生产成本低、更换方便等优点,能大大提高产品的生产效率,降低工人劳动强度。

The working conditions of zirconium alloy extrusion rod are very bad.The extrusion rod must bear huge and periodically varying extrusion stress,which puts forward a high requirement for the structure and strength of the extrusion rod.To a small size zirconium alloy extrusion process,the shortcomings of the conventional extrusion rod are analyzed,and a special extrusion rod is designed in this paper.The extrusion rod with sectional stepped structure has the advantages of low production cost and convenient replacement.It can greatly improve the production efficiency of products and reduce the labor intensity of workers.
