【摘要】：為優(yōu)化熱沖壓模具的冷卻系統(tǒng),減小各型面水管之間的流速差異,提高成形件的產(chǎn)品質(zhì)量,針對大流速型面水管,提出了將該水管的連接水管沿兩個不同方向進行偏置以降低流速的方法。以各型面水管的流速標準差為質(zhì)量指標,設(shè)計正交試驗,得到最佳偏置距離。由優(yōu)化后的冷卻系統(tǒng)流場及模面溫度分析可知,兩種偏置下各管道流速均勻性分別提高了86.2%和77.6%,模面最高溫度分別下降了18.5和11.6℃,模面平均溫度分別下降了13.0和5.3℃。搭建了相應的試驗系統(tǒng)進行流速測試,試驗結(jié)果和仿真吻合。研究表明,該方法能有效改善模具冷卻水管流速不均,提高模面溫度均勻性。
[Abstract]:In order to optimize the cooling system of hot stamping die, reduce the difference of flow velocity between different surface water pipes, and improve the product quality of forming parts, aiming at the high velocity surface water pipe, The method of biasing the connecting pipe along two different directions in order to reduce the velocity of flow is put forward. Based on the standard deviation of flow velocity of various surface water pipes, the orthogonal test was designed and the optimum offset distance was obtained. From the analysis of the flow field and mold surface temperature of the optimized cooling system, it can be seen that the flow velocity uniformity of each pipe increases by 86.2% and 77.6% respectively, the maximum temperature of the mold surface decreases by 18.5 鈩，
