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 flange in the draw operation.Second,lines or ridges will be left in the flange as an attempt is made flatten or straighten the die radius from the first draw.
4) By drawing a flangeless cup atthe draw,cup removal can be greatly simplified by allowing the cup to be drawn straight through the die ring and allowed to exit the bottom die by gravity,much like a pierce slug is forced through a die cavity and ejected out the bottom of the die.
Next month we'll continue this discussion.Until then,use the preceding guidelines to decide how you would draw the cup in Fig.2--flange or no flange.

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.
