H62铜螺旋波纹管增量成形研究
|
摘要
为研究H62铜螺旋波纹管的成形方式和成形极限,开展管材增量成形的ABAQUS模拟与试验研究。首次采用管材增量成形方式加工螺旋波纹管,通过模拟与试验相结合的方式,优化管材增量成形的各工艺参数,结合理论分析提高H62铜螺旋波纹管的成形精度及成形极限。试验结果表明,当工具头的单次进给量为0.50mm,主轴转速为15r/min,工具头的轴向进给速度为5mm/s时,螺纹深度极限提高。当螺纹深度为2.5mm时,波纹管的成形质量最好,当螺纹深度大于6mm时,成形质量显著下降。
In order to study the forming method and forming limit of H62 copper spiral corrugated tubes, ABAQUS simulation and experimental research on tube incremental forming are carried out. For the first time, the spiral corrugated bellows are processed by the incremental tube forming method. Through the combination of simulation and test, the process parameters of the incremental forming of the tube are optimized, and the forming precision and forming limit of the H62 copper spiral corrugated tube were improved by theoretical analysis. The test results show that when the single feed of the tool head is 0.50 mm, the spindle speed is 10 r/min, and the axial feed speed of the tool head is 6.7 mm/s, the thread depth limit is increased. When the thread depth is 2.5 mm, the forming quality of the bellows is the best, and when the thread depth is more than 6 mm, the forming quality is remarkably lowered.
