中文摘要：针对防尘盖零件的外观尺寸，计算出对应的毛坯件尺寸，并判断出其拉深次数和是否需要在拉深时使用压边装置。为验证理论计算的准确性，利用DYNAFORM软件对该零件拉深成形过程进行模拟。模拟结果表明：毛坯尺寸模拟结果和理论计算结果符合良好。在理论计算出的压边力范围内，压边力为20190N时，可以获得成形质量良好，无明显起皱和开裂的零件。
英文摘要：The blank size and the draw time was calculated according to the size of the dust cover. It was estimated whether the binder was necessary to use. The Dynaform software was used to simulate the draw to test the accuracy of the theoretical calculation. The results showed that the simulated result of the blank was consistent with that of the theoretical calculation. In the range of the binder force by the theoretical calculation, the part had the good forming quality without obvious wrinkle and crack with 20190N binder force.
