翻译求助~

哪位高才帮忙翻译成英文~谢谢了,希望可以专业点~
一、引言
连杆是发动机中高精度的关键零件，由连杆体、连杆盖共同组成。在传统制造工艺中，连杆体和盖的制造依赖两种方法：1)连杆体和盖整体锻造→锯切分离→接触面机加工→装配。2)连杆体—盖分别锻造→接触面机加工→装配。采用上述两种工艺，不仅需对连杆体和盖的联接面进行铣削和磨削，并且在该联接面上还要钻铰螺栓定位孔和攻螺纹孔，或者切制端面齿，钻铰定位销孔和钻螺栓孔等，以便将来能使连杆体—盖实现精确合装。为此，需要较多的加工机床，经过十几道工序，耗费大量的加工工时。
针对连杆传统制造工艺中的缺点，为了降低制造费用和工时，提高配合精度，连杆断裂剖分工艺被提出，并首先于80年代中，由Alfling公司在德国申请专利。其后，有关研究不断在美、德获得进展。进入90年代，该工艺在工业发达国家进入实际应用生产阶段。适用的毛坯由最初的粉末锻造连杆，发展到中高碳钢锻造连杆，使用的厂家覆盖了美国三大汽车公司，以及德国奔驰、宝马等著名企业。目前国内应用该技术的厂家是一汽大众发动机厂，引进德国技术装备，适用于每缸五气门新型发动机连杆。

Answer 1

First, introduction the connecting
rod is in the engine the high accuracy crucial element, by the continually body of rod, the connecting rod cap is composed together. In the tradition fabrication technology, the manufacture which and covers including the body of rod relies on two methods: 1) continually the body of rod and covers the whole forging -> sawing separation -> contact face machining -> assembly. 2) the body of rod - covers continually forges -> the contact face machining -> assembly separately. Uses the above two crafts, not only need the joint surface which and covers to continually the body of rod carry on the milling and the grinding, and must drill the articulation bolt index hole and the tapping hole on this joint surface, or cuts the system end surface tooth, drills the articulation localization cotter hole and drills the bolt hole and so on, so that the future can cause the body of rod - lid to realize continually puts all in one load precisely. Therefore, needs the many processing engine beds, passes through several working procedures, consumes the massive processing man-hour. in view of connecting rod tradition fabrication technology in shortcoming, to reduce the factory expense and the man-hour, increases the grade of fit, the connecting rod break cutting in half craft was proposed, first and in the 80s, applies for the patent by Alfling Corporation in Germany. After that the related research in US, Germany makes the progress unceasingly. Since the 90s, this craft enters the practical application production base in the industrially advanced country. The suitable semifinished materials from the initial powder forging connecting rod, developed the high-carbon steel forging connecting rod, the use factory have covered the US three big Car companies, as well as Germany ran quickly, the BMW and so on famous enterprise. At present the domestic application this technology's factory is the FAW Populace Engine plant, introduces Germany technical equip, is suitable in each cylinder 5 bad attitudes gate new engine connecting rod.

One, the foreword connecting rod is that the engine is hit by the high-accuracy key part , the body , the connecting rod cover up with common composition from the connecting rod. In tradition manufacturing engineering, the connecting rod body and the fabrication printing on are dependent on two kinds method: Separation-> contact surface machine work-> assembles the 1) connecting rod body and the cover overall forging-> saw by all means. Forging-> contact surface machine work-> assembles 2) connecting rods bodies cover respectively.Or adopt two above-mentioned species handicrafts, not only need carrying out bright metal on the connecting rod body and the conjunction plane printing on cutting the sum grinding, and surface wants to study hinge bolt allocation hole intensively and to attack a screwed hole too in that linkup, be sure to make the end face tooth, drilling the hinge locating pin hole and drilling the bolt hole and so on, jointly pretends to be able to make connecting rod body cover come true in the future accurately. For this purpose, need more treating machine tool , more than ten working procedure pass, consume large amount of treating a working hour.
Specifically for shortcoming in connecting rod tradition manufacturing engineering, in order to reduce fabricating cost and the working hour , improve the accuracy fitting, the connecting rod breaks analysing mark of handicraft being suggested that , the company applies for a patent and first among the eighties, from Alfling in Germany. Posterior , unceasingly in connection with studying American-Germany acquisition progresses. Enter the nineties , be a handicraft's turn to enter actual application in the industrialized country producing a stage. And the blank suitable for use forges a connecting rod from initial powder , develop to middle high-carbon steel forging connecting rod, the manufacturer who is put into use has covered three big USA automobiles companies, famous enterprise such as Germany Benz , BMW. Applying the manufacturer who is a technology's turn at present in the homeland is a masses of China FAW Group Corporation engine factory , introduces Germany equipment, apply to five air valve new model engine connecting rods per jar.

Linkage is the key engine of high-precision parts of the link, connecting rod covered together. In traditional manufacturing processes, and build the linkage of the two methods rely on the manufacturers: 1) link and covered the whole of forging → sawing separation → contact surface machining → assembly. 2) linkage of - were covered forging contacts → machining → assembly. Using these two processes, not only to be covered and the linkage of the connection of a milling and grinding, and the connection to surface drilling hinge bolt holes and positioning Tapping hole, cut or end-system gear, drilling hinge pin Drilling holes and bolt hole so as to enable linkage of the future - with a cover to achieve accurate. To this end, need more processing machine, after more than 10 processes, a significant amount of processing time.
Linkage traditional manufacturing process for the shortcomings, in order to lower manufacturing costs and working hours, with improved accuracy, link fault subdivision process was proposed and first in the 1980s, from Alfling companies to apply for a patent in Germany. Since then, the study in the United States, Germany progress. In the 1990s, the process in the industrialized countries into the practical application stage of production. The application of the powder from the initial rough forging links, to the development of high-carbon steel forging links, the use of the manufacturers cover the three major U.S. car companies, and the German Mercedes-Benz, BMW, and other famous enterprises. At present the domestic application of the technology manufacturers is the FAW-Volkswagen engine plant, the introduction of German technology and equipment, applicable to the five-valve per cylinder engine new link.
