Question

可以帮忙翻译下么？

Rotary forming is a method of forming various profiles
from circular rods, tubes and sheet-metal blanks by a rotary
compressive process. This process is not only the most
popular method for forming the threaded portion of bolts
and machine screws, but also increases its application to
the production of gears, balls, rings, cylindrical hollow bodies,
conical hollow bodies, various shafts and the other axisymmetrical
profiles. Rotary forming of circular rods and
disks is called forming by rolling, while rotary forming of
sheet-metal and tubular blanks is called spinning. Each process
of rotary forming has its own application and features
concerning its forming technology. Furthermore, there are
many advantages common to all rotary forming processes.
They are summarized as follows [1]:
(a) The forming forces can be reduced due to the localized
deformation in rotary forming, and then the stiffness of
a rotary forming machine becomes less than that of a
conventional forging press.
(b) High productivity, continuous production and automation
are attainable.
(c) The material consumption and the total cost for production
can be reduced.
(d) The wear of tools due to the rolling contact can be reduced,
and then the tool life is prolonged.
(e) The surface finish and the dimensional accuracy of products
are relatively high.
(f) The fiber structure formed during the process improves
the strength of products.

你好，我也是学工科的，专业是金属材料压力加工，学过你要翻译内容的相关知识，所以对你要翻译的东西比较熟悉，可以参考下我的 翻译，希望对你有用哈~~

译文：回转成型（也可以说是旋转成型）是通过旋转压缩工序将圆棒、管、薄板材做成各种配件的一种方法。该工序不仅是螺纹和机械螺丝成型的主流方法，同时也应用于齿轮、球件（没见过，如果楼主知道正确翻译请别介意）、环件、圆柱空心体、锥形空心体、各种轴类零件和其它轴对称的零部件的生产。用来成形圆棒和圆盘的回转成型也叫轧制，而薄板材和管材的成形方式叫旋压。不同的成形工艺所对应的回转成型的方法都有不同的应用领域和特征。此外，回转成型工序还有许多普遍的优点。
优点如下：
（a）成形应力可根据局部应变减小，相比于传统锻造工序，回转式成形机所加工的零部件的硬度更 小。
（b）成型率高，能够连续作业，已实现自动化生产。
（c）耗材量和产品总成本降低。
（d）轧制过程中的装备的耗损减少，使用寿命得到延长。（这里的rolling contact可能不是指轧 制过程，可能是机器运作过程中部件和轧辊接触的阶段）
（e）产品的表面光洁度和尺寸精度相当高。
（f ）成形过程中所产生的纤维织构提高了产品的强度。

如果还有专业名词不明白，可以再详细解答~~~

Answer 2

旋转成型是形成各种profilesfrom圆杆的方法，由一个rotarycompressive过程管和金属板坯件。这个过程不仅是形成boltsand机螺钉的螺纹部分的流行方法，但也增加了其应用于生产的齿轮，球，环，圆柱形中空体，锥形空心体，各种轴和其他axisymmetricalprofiles。旋转的圆杆anddisks形成被称为形成滚动，而旋转成形冲压金属管状坯料被称为纺纱。每个旋转形成过程有各自的应用范围和featuresconcerning成形工艺。此外，有很多的优势，共同旋转成形过程。他们如下[ 1 ]：（一）力量的形成可能是由于在旋转形成的localizeddeformation降低刚度，然后一个旋转成型机变得低于常规模锻压力机。（B）生产效率高，连续生产并可实现。（C）材料消耗和productioncan总成本降低。（D）的工具，由于滚动接触磨损可以减少，然后该工具寿命延长。（E）的表面光洁度和尺寸精度是比较高的。（F）产品的过程提高了强度的过程中形成的纤维结构。
