第 5 章塑料成型及模具5. 1. 1 注塑模具5.1.1 一般注塑成型技术的处理器的持续发展的要求越来越多。
注塑成型过程中最重要的问题无疑是正确的注射。
因为设计成型形状的影响不大,如有的建设最多样化的注塑部件的机器。
高效的生产主要取决于注塑模具。
模具的耐久性取决于他们的护理和治疗。
由于总是硬化和地面的运动部件和模具型腔,他们之间产生500000和100000000张。
为了便于建设,降低制造成本,注塑模具成为标准化.一些公司提供基本现成的方形或圆形,立即使用. 只需插入标准或卸料板模具设计的基础,那么,必须安装到基础。
5.1.2 个基本模具结构5.1.2.1 工作原理注塑模具基本上由两个半形. 模具的一半包含浇道衬套和热流道系统,喷射系统。

《材料成型及控制工程专业英语阅读》翻译系列11.1

《材料成型及控制工程专业英语阅读》翻译CHAPTER 11 CASTING铸造工艺的主要分类依据是其所应用的铸造种类。
这些铸型是型砂、塑料粘结壳型、永久型和半永久型金属型。
压铸用金属型、石膏型、熔模铸造铸型。
11.1 各种铸造工艺砂型的第一步是制作一个金属的或木质的模样,模样就是将要制成的铸件的复制品,但尺寸要比铸件的稍大一些。
模样通常是由两个或多个部分组成,从而能容易地从铸型中被取出来。
为了制作铸型,型砂被压实并填充在模样的四周,而型砂是放在一个像箱子似的容器也就是沙箱里的。
沙箱内充满砂型之后,撤出模样,就留下可一个与成品铸件形状相似的型腔。
如果铸件上有中空的部位,例如:车轮里的一个轴心孔,那么型腔里的孔洞形状的地方必须填上型砂。
这些制空的形状就是所谓的型芯。
用于铸件和型芯的型砂是由粘土和颗粒粘结剂混合成的。
如果砂型经过了烘干,那么就称之为干砂型:如果是在潮湿的状态下使用,则成为湿型砂。
干砂型比湿砂型具有更大的强度,更大的抗腐蚀能力和抗碎性。
填充型砂之前,在模样的表面覆上一层细的沙也就是所谓的面纱。
这样可以提高砂型铸件的表面质量。
塑性粘结壳型铸件是砂铸的一种改进形式。
一个金属模样加热到350℉左右(175℃),然后夹放到一个充满细砂和热固树脂的箱子上面。
当箱子倒过来,它里面的物质就掉落在热模样上,那么树脂受热就会软化。
这样,就在模样的周围形成以薄壳层的铸件材料。
然后箱子转回到其初始的位置,未反应的树脂和砂型就从模样上掉下来。
当树脂有足够的时间充分(完全)固化之后,这么壳层就剥落下来。
最终的铸型由两片相配的壳层组成,壳层紧紧地靠在一起,且四周是由沙箱中的金属颗粒支撑物所包围,而使用这种颗粒物提高了冷却和凝固速度。
永久型和半永久型的铸件是由金属制成的。
如果需要永久型铸型甚至使用金属型芯。
半永久型使用砂型芯。
铸型的两部分通常紧紧地铰接在一起,并使用螺钉装置紧固。
铸型图层或涂料由耐火材料,像石墨或三氧化二铁这样的润滑剂和粘结剂组成,其有助于铸件从铸型中取出。

3. 1. 1 Dynamic Structural Change
During the deformation of austenite at hot-working temperatures and constant strain rate, the characteristic form of stress-strain curve observed is illustrated in Fig. 3. 1. These curves are for low-alloy steels,tested in torsion,but are similar to those obtained for other steels in the austenitic condition tested in torsion,tension,or compression. After initial rapid work-hardening the curves go through a maximum associated with the occurrence of dynamic recrystallization. The peak in flow stress occurs after some low fraction of recrystal lization has taken place so the strain to the peak (εp) is always greater than the critical strain for dynamic recrystallization (εc).
It can be seen from Fig.3.1 that εp increases systematically with Zener-Hollomon parameter (Z),independent of the particular combination of strain rate (ε) and temperature (T/K) in the relationship Z = εexp Qdef/RT

材料成型级控制工程专业英语阅读材料成型级控制工程专业英语阅读1.2.1 Plain Carbon Steel 普通碳钢Hot-rolled steel delivered (供给)by steelmaking works as rolled sections(bars, beams,sheets.tubes,etc) is the most wildly used material for manufacture of various machines,machine tools, building structures,consumer goods,etc.Delivered steel should have the properties as specified by State Standards(国家标准).钢铁制造车间供给的热轧钢主要为棒材、柱材、板材、管材等,热轧钢是制造各种机械、机器工具、建筑结构和消费品中应用最广泛的材料。
所供给的钢应具有国家标准规定的各种性能。
In the RSSU.Plain carbon steels are classified into three groups:A, B and C,depending on their application.在RSSU中,普通碳钢根据其用途分为A、B、C三类。
A: If a steel is to be used for making products without hot working (welding, Forging.Etc.). Its structure and properties in the final product will be the same as delivered from the rolling mill.In that case the user requests for a steel of warranted(保证)mechanical properties,while the chemical composition is not guaranteed(保证、担保).A:如果钢在制造产品的过程中没有进行热加工(焊接、锻造等),则最终产品的组织和性能将与轧厂提供的相同。
这种情况下,用户只需要求材料应有的机械性能,而不必保证其成分。
B: If a steel is to be subjected to hot working(forging,stamping,etc),its initial structure and mechanical properties will be changed.In that case the composition of the steel will be of prime importance for the user,since it determines the conditions of hot working and the final mechanical properties of steel products.Now a steel of warranted composition is delivered to the user.B.如果钢要进行热加工(锻造、冲压等),则其初始组织和机械性能将会改变。
此时/在这种情况下,钢的成分对用户来讲是最重要的,因为它(成分)决定了热加工的条件,钢制品的最终机械性能。
因此,提供给用户的钢应保证其成分含量。
C: If a steel is to be welded.the user wants to know the composition of the steel.since it determines the properties of the metal in the zone subjected to thermal effect of weld(焊接热影响区).The user is also interested in the initial mechanical properties of the metal,since these properties will remain the same in portions not subjected to welding.In that case the metal is delivered with warranted composition and mechanical properties.C.如果钢要进行焊接,则用户需要知道钢的成分,因为成分决定钢焊接时热影响区的性能。
用户也会对钢材的原始机械性能感兴趣,因为未焊接的部分的性能是原始性能。
这种情况下,供给用户的钢应具有规定的成分和机械性能。
General-purpose plain steels are not alloyed.Some alloying elements may sometimes be present in them occasionally and their content(含量) is limited.非特殊用途/一般用途的普通钢不是合金钢。
一些合金元素偶尔会出现,其含量受限制。
The presence of silicon and manganese may be due to the steel—making process(the necessity of deoxidation脱氧).Surphur (硫)and phosphorus(磷) are harmful impurities(杂质) in steel and their content should be minimized as it may affect the quality of steel.在钢冶炼过程中由于脱氧的需要,会出现硅和锰。
硫、磷是钢中有害的杂质,应尽可能减少其含量,它们会影响钢的质量。
The principal element whose content is responsible for the properties of steels is carbon影响钢性能最主要的元素是碳。
1.3Non-ferry AlloysAlthough ferrous alloys ale used in the majority of metallic applications in current engineering designs,non—ferrous alloys play a large and indispensable role in our technology. As compared to ferrous alloys,the list of non—ferrous alloys is,of course,long and complex.We shall briefly list the major families ofnon—ferrous alloys and their key attributes.尽管现代工业设计中,铁合金是主要应用的金属,但是非铁合金在当前科技中也起着很大并不可替代的作用。
当然,与铁合金相比,非铁合金的种类多且复杂。
我们将简要介绍几种非铁合金及其主要特征。
Aluminum alloys are best known for low density and corrosion resistance. Electrical conductivity,easy of fabrication,and appearance are also attractive features.Because of these,the world production of aluminum roughly doubled in one recent 10 year period.Ore reserves for aluminum are large (representing 8%of the earth’s crust) and aluminum can be easily recycled铝合金以其低密度和腐蚀抗力而闻名。
电导率、易加工以及好的外观也是其具有吸引力的特征。
基于以上特点,近10年来铝合金的产量几乎翻了一番。
铝矿石的产量很大(占地壳的8%),并且铝是可以回收的。
Magnesium alloys have even lower density than aluminum and,as a result,appear in numerous structural applications such as aerospace designs.Aluminum is a fcc material and therefore has numerous (12) slip systems, leading to good ductility.By contrast.magnesium is hcp with only three slip systems and characteristic brittleness.镁合金的密度比铝合金的还低,因此,设计航空飞行器时大量的结构件用镁合金。
铝合金是面心立方结构金属,因此,有12个滑移系,使其延展性好。
相反,镁合金是密排六方结构,仅有3个滑移系,易脆断(具有脆性)。
Titanium alloys have become widely used since World WarⅡ.Before that time,a practical method of separating titanium metal from reactive oxides and nitrites was not available. Once formed, titanium’s reactivity works to its advantage.A thin tenacious oxide coating forms on its surface, giving excellent resistance to corrosion. This “passivation” w ill be discussed in detail later. Titanium alloys,like Al and Mg,are of lower density than ion. Although more dense than Al or Mg,titanium alloys have a distinct advantage of retaining strength at moderate service temperatures, leading to numerous aerospace design applications. Titanium shares the hcp structure with magnesium leading to characteristically low ductility. However,a high temperature bcc structure can be stabilized at room temperature by certain alloy additions such as vanadium.二战以后钛合金被广泛应用,在此之前,还没有通过活性氧和硝酸盐分离钛金属的工艺。
