| 摘要: |
| 为解决6063铝合金蒸汽腔充入工质时易产生开裂和变形问题,改善支承结构成形加工质量,提高承载能力,采用不同热处理状态的6063铝合金进行蒸汽腔阵列支承柱模压工艺实验,探究了成形温度及压力对不同区域支承柱模压成形高度、成形均匀性及硬度的影响规律。实验表明,成形温度和压力为150~350 ℃、40~70 MPa时,O态和T6态材料成形高度均随着温度和压力升高而提高,成形均匀性改善。O态材料在150 ℃时有一定填充高度,350 ℃、70 MPa时支承柱填充饱满,接近最大填充高度1.1 mm,成形均匀；T6态材料在250 ℃以下时无明显填充,350 ℃、70 MPa时3区支承柱高度约为0.8 mm,成形不均匀,相同温度和压力下T6态材料成形性与O态材料相比较差。O态材料成形前后硬度分别为32.65HV0.2和34.98HV0.2,T6态材料硬度由90.7HV0.2下降至成形后的41.7HV0.2。退火处理的O态6063铝合金成形性能显著提高,考虑生产效率和脱模问题,得到的最佳成形工艺参数为成形温度350 ℃,成形压力70 MPa,保压时间5 min,该参数下成形质量显著提高,承载能力较高。 |

| Abstract: |
| To address the issues of cracking and deformation when filling the steam chamber of 6063 aluminum alloy with working fluid, and to improve the forming quality and load-bearing capacity of the support structure, molding experiments were conducted on 6063 aluminum alloy in different heat treatment states. The effects of forming temperature and pressure on the support columns’ height, uniformity, and hardness in different regions were investigated. The experiments show that when the forming temperature and pressure are between 150350 ℃ and 4070 MPa, the forming height of O and T6 materials increases with the increase of temperature and pressure, and the forming uniformity improves. For the O-state material, a certain filling height was achieved even at 150 ℃, and full filling with uniform morphology was obtained at 350 ℃ and 70 MPa, approaching the maximum height of 1.1 mm. In contrast, the T6-state material showed negligible filling below 250 ℃, and the support columns in the three zones reached only about 0.8 mm at 350 ℃ and 70 MPa, indicating poorer formability than the O-state material under the same conditions. The hardness of the O-state material before and after forming was 32.65HV0.2 and 34.98HV0.2, respectively, and the hardness of the T6-state material decreased from 90.7HV0.2 to 41.7HV0.2 after forming. Considering production efficiency and demolding requirements, the optimal forming parameters were determined to be a temperature of 350 ℃, a pressure of 70 MPa, and a holding time of 5 min, which significantly improved the forming quality and load-bearing capacity of the support columns. |
