Question

哪位哥哥姐姐帮我翻译一下以下的一段话

In sheet metal,drawing is a process of forming flat sheet meal into hollow shapes by means of a punch that causes the metal to flow into the die cavity. If the depth is one or more times the diameter ,the process is called deep drawing .The forming of shallow shapes is sometimes referred to as stamping ,but the distinction is not elear since stamping is also used to describe cutting flat figures or patterns.
In deep-drawing ,also called cup or radial drawing ,a parallel-walled cup is crated from a flat blank .The blank may be circular ,rect-angular,or of a more complex outline.The blank is drawn down into the die cavity by action of the punch .Deformation is restricted to the flange and draw radius .No deformation occurs under the bottom of the punch .As the pnch forms the cup ,the amount of material in the flange decreases.
In drawing,the limit of deformation is reached when the load required to defom the flange becomes greater than the load-carrying of the cup wall.The failure site will be in the unworked area near the bottom of the cup wall . The hold-down pressure on top of the blank must be sufficient to keep the material fron wrinkling as it goes into the die ,The deformation limit(limiting drawing ratio or LDR)is the maxiunm blank diameter heat can be drawn into a cup without failure. The percentage of reduction can be calculated as follows:
%Reduction=(D-d/D)*100
Where D=blank diameter
d=punch diameter
The calculation is usually made with the cup-wall inside diameter, which would also bethe draw-pnch diameter.A drawing ratio or percentage reduction of 48%is considered excellent on the first draw . Succeeding draws must be reduced. That is the percentage reduction that can be expected under falvorable conditions without annealing ,for a second draw would be about 30% and about 20% for a third draw.

在钣金，绘画的过程，就是一个形成平板餐成空心形状通过一个冲床造成金属流入模腔。如果深度是一个或更多倍的直径，这一过程称为拉深。形成浅层形状有时被称为冲压，但区别并不elear以来，冲压，也被用来形容切割单位数字或图案。
在深冲，又称为杯或径向绘画，一个平行的薄壁杯装箱，从一个单位的空白。空白，可通知， rect角，或者一个更复杂的outline.the空白，是取用进入模腔通过行动的力度。变形仅限于法兰和借鉴半径之内。不变形下出现底部的力度。作为pnch形式杯，材料数量，在法兰跌幅。
在绘画，极限变形是达到负载时须defom法兰变得大于承载的杯子壁失败土地将在unworked面积近底部杯墙。船舱向下的压力，再加上空白，必须足以把物质fron起皱的，因为它涉及到模具，变形限制（限绘画比率或低剂量辐射） ，是maxiunm毛坯直径热量，可以得出成杯无故障。百分比减少，可以计算如下：
％减少= （四三维/四） * 100
其中d =毛坯直径
d =直径冲床
计算通常是与世界杯壁内直径，这也将是贝特拉pnch diameter.a绘画比率或百分比减少48 ％的被认为是优秀的就先参加抽奖。接替提请的要降下来。这是削减百分比表示，可以预料，下falvorable条件未经退火，为第二次提请将会减少约30 ％和20 ％左右，为第三次抽奖。

好长啊
