The 3D design of the strengthen board of the windscreen wiper has been introduced on the design of the obtruding technics .

该冲压零件来源于十堰市先锋模具公司生产的雨刷机加强板，零件尺寸见图1

Fixed on the obtruding technics scheme, and made the 3D design of the pressing dies by the advanced CAD/CAE/CAM software --Pro/Engineer(in model Part、Assembly、Manufacturing and Drawing) emphatically, by getting across the analysis of the partˊs structure and combining the punch knowledge.

该零件的尺寸是通过测量得到的，在零件图上未注明尺寸公差，精度要求不高。材料为08钢，料厚为0.9mm。结合以前所学过的模具知识，运用Pro/Engineer做冷冲压模具三维设计。

Through analysis of the oil-seat oiling parts of the structure and characteristics of the processing requirements of the development of a more reasonable fixture design, so as to guarantee the precision machining of parts will provide an economical and practical technology equipment, has some practical value.

本文通过分析注油器油阀座零件的结构特点和加工要求，制定了一套较合理的夹具设计，从而为保证该零件的加工精度将提供一种经济实用的工艺装备，具有一定的实用价值。

For internal high pressure forming of a hollow part with big difference on section perimeter, the problems of axial feeding and preforming are necessary to be solved to produce qualified parts with more uniform thickness distribution.

截面周长差较大的空心零件的内高压成形需要解决膨胀区的轴向补料问题和预成形问题，才能获得壁厚分布较为均匀的合格零件。

But figuring out how to efficiently reuse returned items can increase profitability by reducing materials requirements: Every component reinserted in the forward supply chain is one unit fewer that must be procured or manufactured.

但若是能想出如何有效率地重复使用退货商品，就可以降低材料需求，提高获利能力：顺向供应链每重新使用一个零件，就能减少采购或制造一个零件。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
