摘　　要：针对304不锈钢筒形件在旋压过程中因旋压工艺参数组合不当而引起的起皮、开裂、内壁划伤及扩径等一系列问题,以毛坯壁厚为12 mm、内径为Φ292 mm的304不锈钢管为对象进行研究,基于Simufact Forming有限元软件对304不锈钢筒形件旋压成形过程进行仿真,并分析了不同工艺参数组合对等效塑性应变、等效应力及壁厚差的影响。仿真结果显示,最佳成形参数组合为:旋轮圆角半径rρ为6 mm、旋轮进给速度v为80 mm·min^(-1)、减薄率ψ_t为40%。利用最佳参数组合进行工艺试验,成功旋制了外径为Φ300.8 mm的不锈钢筒形件,壁厚差为0.04~0.08 mm,证明了有限元仿真的模拟结果对于304不锈钢三轮错距旋压工艺研究具有重要的意义。For a series of problems such as peeling,cracking,inner wall scratching and diameter expansion caused by improper combination of spinning process parameters of 304 stainless steel cylindrical parts during the spinning process,taking the 304 stainless steel pipe with a blank wall thickness of 12 mm and an inner diameter ofΦ292 mm as the research object,the spinning process of 304 stainless steel cylindrical parts was simulated based on Simufact Forming finite element software,and the influences of different process parameter combinations on equivalent plastic strain,equivalent stress and wall thickness difference were analyzed.The simulation results show that the optimal combination of forming parameters is that the corner radius of rotary wheel rρ=6 mm,the feed speed of rotary wheel v=80 mm·min^(-1),and the thinning rateψt=40%.The stainless steel cylindrical parts with the outer diameter ofΦ300.8 mm are successfully spun by using the optimal parameter combination for process test,and the wall thickness difference is 0.04-0.08 mm,which proves that the results of finite element simulation are of great significance for the research on the three-wheel staggered spinning process of 304 stainless steel.
