There also are good reasons why a flangeless cup is produced in the first draw operation.
1) Once the critical punch load is passed as material flows toward the die radius, the amount of blank-edge move-ment becomes irrelevant. A general rule is to move the blank edge to as small a diameter as possible since forming severity is not increased. This is accomplished by removing the entire flange.
2) Due to the design of redraw dies,a flange can beplaced on a flangeless cup by controlling the redraw punch travel. The flange is created under the blankholder as shown in Fig. 3.
3) If a flange has been left on the cup die in the first draw operation, it is not practical to remove the flange or reduce its diameter in a redraw operation because the redraw blankholder design will not prevent wrinkling if the flange is placed in compression, as seen in Fig. 4. This also presents two other disad-vantages. First, an excessiveamount of trim material is created by leaving a f

也有良好的原因flangeless杯是在生产第一提请运作。
1 ）一旦关键的冲压负荷是通过物质流动对模具半径，金额空白的尖端移动- ment变得无关宏旨。一般规则是动议空白的优势，小的直径尽可能以来形成的严重性，是没有增加。这是通过删除整个法兰。
2 ）由于设计重绘去世，法兰可beplaced就一flangeless杯控制重绘冲床旅行。法兰是创造下压边所示，在图。 3 。
3 ）如果一个法兰一直留在杯模具在第一次制定的运作，这是不实际，以消除法兰或减少其直径在1重绘的运作，因为重绘压边设计，将无法防止起皱，如果法兰是放置在压缩，可以看出在图。 4 。这也提出了其他两个disad -优势。首先，一excessiveamount的装饰材料是创造留下了法兰在抽签的运作。第二，线条或山脊，将留在法兰作为一个企图是扁的或拉直模具半径从第一次抽奖。
4 ）绘制flangeless杯atthe借鉴，杯去除，可大大简化，让杯，以订定直通模具环，并获准出境底部的模具重力，很像一皮尔斯塞是被迫通过模具型腔和弹射出底部的模具。
下个月我们将继续讨论。在那之前，使用前的指引，以决定如何，你将提请杯在图。 2 -法兰或没有法兰。
在网上翻的，应该没错啦
不给分谁做？呵
