本文系根据国内外有关资料,对影响家用洗衣机金属内筒拉伸成形的参数进行了系统的分析。指出了内筒整体一次拉伸成形的可能性。但能否成形,还必须视诸因素的影响。文中还提出了坯料尺寸和形状计算的简便方法。最后以一实例来证明上述的分析。 In this paper, based on the relevant information at home and abroad, the impact of domestic washing machine metal inner tube tensile forming parameters were systematically analyzed. The possibility of a single stretch forming of the entire inner cylinder is pointed out. However, whether shaping or not depends on the factors. The paper also proposed a simple method of calculating the size and shape of the blank. Finally, an example to prove the above analysis.
