冲压模具毕业设计论文摘要

模具毕业论文冲压模具设计中对机械运动的控制和运用摘要：在冲压过程中，机械运动贯穿始终。各种冲压工艺的实现都有其基本运动机理，这种运动是与模具密切相关的，各种模具的结构设计和力学设计最终都是为了满足其能够实现特定运动的要求。设计的模具能否严格完成实现冲压工艺所需的运动，直接影响到冲压件的品质，所以在模具设计中应对机械运动进行控制。同时为了达到产品形状尺寸的要求，不能够拘泥或局限于各种工艺基本运动模式中，而应不断发展和创新，在模具设计中对机械运动灵活运用。关键词：冲压模具设计，机械运动，控制，灵活运用1.引言本论文是以冲压工艺学基本理论为依据，通过对各种冲压工艺基本运动的分析，提出了对冲压模具设计的要求。首先阐述冲压过程中，机械运动的基本概念，然后逐项分析了冲裁、弯曲、拉深工艺的基本运动机理，指出模具设计中应着重控制到的内容，并介绍了在模具设计中对机械运动灵活运用的方法和一些实例。最后总结了根据具体情况进行产品工艺运动分析的方法，并强调在模具设计中，对机械运动的控制和灵活运用对提高设计水平和保证冲压件品质的重要意义。2.冲压过程中机械运动的概述冷冲压就是将各种不同规格的板料或坯料，利用模具和冲压设备（压力机，又名冲床）对其施加压力，使之产生变形或分离，获得一定形状、尺寸和性能的零件。一般生产都是采用立式冲床，因而决定了冲压过程的主运动是上下运动，另外，还有模具与板料和模具中各结构件之间的各种相互运动。机械运动可分为滑动、转动和滚动等三种基本运动形式，在冲压过程中都存在，但是各种运动形式的特点不同，对冲压的影响也各不相同。既然冲压过程存在如此多样的运动，在冲压模具设计中就应该对各种运动进行严格控制，以达到模具设计的要求；同时，在设计中还应当根据具体情况，灵活运用各种机械运动，以达到产品的要求。冲压过程的主运动是上下运动，但是在模具中设计斜楔结构、转销结构、滚轴结构和旋切结构等，可以相应把主运动转化为水平运动、模具中的转动和模具中的滚动。在模具设计中这些特殊结构是比较复杂和困难，成本也较高，但是为了达到产品的形状、尺寸要求，却不失为一种有效的解决方法。3.冲裁模具中机械运动的控制和运用冲裁工艺的基本运动是卸料板先与板料接触并压牢，凸模下降至与板料接触并继续下降进入凹模，凸、凹模及板料产生相对运动导致板料分离，然后凸、凹模分开，卸料板把工件或废料从凸模上推落，完成冲裁运动。卸料板的运动是非常关键的，为了保证冲裁的质量，必须控制卸料板的运动，一定要让它先于凸模与板料接触，并且压料力要足够，否则冲裁件切断面质量差，尺寸精度低，平面度不良，甚至模具寿命减少。按通常的方法设计落料冲孔模具，往往冲压后工件与废料边难以分开。在不影响工件质量的前提下，可以采用在凸凹模卸料板上增加一些凸出的限位块，以使落料冲孔运动完成后，凹模卸料板先把工件从凹模中推出，然后凸凹模卸料板再把废料也从凸凹模上推落，这样一来，工件与废料也就自然分开了。对于一些有局部凸起的较大的冲压件，可以在落料冲孔模的凹模卸料板上增加压型凸模，同时施加足够的弹簧力，以保证卸料板上压型凸模与板料接触时先使材料变形达到压型目的，再继续落料冲孔运动，往往可以减少一个工步的模具，降低成本。有些冲孔模具的冲孔数量很多，需要很大冲压力，对冲压生产不利，甚至无足够吨位的冲床，有一个简单的方法，是采用不同长度的2～4批冲头，在冲压时让冲孔运动分时进行，可以有效地减小冲裁力。对那些在弯曲面上有位置精度要求高的孔（例如对侧弯曲上两孔的同心度等）的冲压件，如果先冲孔再弯曲是很难达到孔位要求的，必须设计斜楔结构，在弯曲后再冲孔，利用水平方向的冲孔运动可以达到目的。对那些翻边、拉深高度要求较严需要做修边工序的，也可以采用类似的结构设计。4.弯曲模具中机械运动的控制和运用弯曲工艺的基本运动是卸料板先与板料接触并压死，凸模下降至与板料接触，并继续下降进入凹模，凸、凹模及板料产生相对运动，导致板料变形折弯，然后凸、凹模分开，弯曲凹模上的顶杆（或滑块）把弯曲边推出，完成弯曲运动。卸料板及顶杆的运动是非常关键的，为了保证弯曲的质量或生产效率，必须首先控制卸料板的运动，让它先于凸模与板料接触，并且压料力一定要足够，否则弯曲件尺寸精度差，平面度不良；其次，应确保顶杆力足够，以使它顺利地把弯曲件推出，否则弯曲件变形，生产效率低。对于精度要求较高的弯曲件，应特别注意一点，最好在弯曲运动中，要有一个运动死点，即所有相关结构件能够碰死。有些工件弯曲形状较奇特，或弯曲后不能按正常方式从凹模上脱落，这时，往往需要用到斜楔结构或转销结构，例如，采用斜楔结构，可以完成小于90度或回钩式弯曲，采用转销结构可以实现圆筒件一次成型。值得一提的是，对于有些外壳件，如电脑软驱外壳，因其弯曲边较长，弯头与板料间的滑动，在弯曲时，很容易擦出毛屑，材料镀锌层脱落，频繁抛光弯曲冲头效果也不理想。通常的做法是把弯曲冲头镀钛，提高其光洁度和耐磨性；或者在弯曲冲头R角处嵌入滚轴，把弯头与板料的弯曲滑动转化为滚动，由于滚动比滑动的摩擦力小得多，所以不容易擦伤工件。5.拉深模具中机械运动的控制和运用拉深工艺的基本运动是，卸料板先与板料接触并压牢，凸模下降至与板料接触，并继续下降，进入凹模，凸、凹模及板料产生相对运动，导致板料体积成形，然后凸、凹模分开，凹模滑块把工件推出，完成拉深运动。卸料板和滑块的运动非常关键，为了保证拉深件的质量，必须控制卸料板的运动，让它先于凸模与板料接触，并且压料力要足够，否则拉深件容易起皱，甚至裂开；其次应确保凹模滑块压力足够，以保证拉深件底面的平面度。拉深复合模设计合理，可以很好地控制结构件的运动过程，达到多工序组合的目的。例如典型的落料拉深切边冲孔复合模具的设计。另外，有些装饰品和日用品的拉深件需要有卷边（或滚边）工序，模具设计中也用到了滚轴结构，所以在卷边过程中滚动的摩擦力非常小，不容易擦伤工件表面。对那些需要在马达中旋转的拉深结构件,切边的高度、跳动度等要求相当高，需要在模具中设计特别的旋切结构，利用旋转（切）运动修边，不仅能保证切边的尺寸精度高，甚至切边的毛刺及冲切纹路亦相当美观。值得一提的是，此旋切结构在实际设计改良后，已经非常易于模具加工制作，并且已运用于连续拉深模具当中。6.连续模具中机械运动的控制和运用连续模具中常常同时包括了冲裁、弯曲和拉深等冲压工艺，因而其冲压过程中的机械运动也包括了这三种工艺的基本运动模式，对连续模具中运动的控制，应分成各基本工艺分别进行控制。通常连续模具要求不断加快冲压速度，提高生产效率，有些形状较复杂、较特别的冲压件，其冲压运动较费时，在连续模具设计中可以分解成效率较高的冲压运动。例如，工程膨胀螺钉圆筒件在连续模具设计中即可将其圆筒成型运动分解为两侧90度圆弧弯曲～中间60度圆弧弯曲～整体抱圆～圆度校正四个工序，不仅提高效率，亦能保证冲压件圆度。需要特别指出的是，连续模具因为在实际生产中还牵涉到送料机、吹风装置等，在设计中应充分考虑到这些因素，让冲床、模具、送料机和吹风装置的运动在时间上配合好，连续模具才能真正顺利生产。7.结束语尽管各种工艺的基本运动原理是不同的，但是也有共同点，就是卸料板（或滑块）的运动是重要的控制因素。实际上，在模具设计当中，产品的冲压工艺不可能都象各种工艺的基本运动那样简单，应当要根据具体情况对产品工艺作好运动分析，再据此作进一步的设计。在对产品工艺运动作分析时，应主要考虑其必要性、时间性、可行性，还应具有创造性。必要性是指运用基本运动原理判断需要那些运动来实现产品工艺；时间性是指所需各项运动的先后顺序；可行性是指能否通过结构设计和力学设计来实现所需运动；创造性是指在前述运动无法被实现或运动无法完全实现产品工艺的情况下，要善于大胆采用新方法去努力实现产品工艺，也就是前面所说的对机械运动的灵活运用。冲压过程存在多种多样的机械运动，而各种机械运动对冲压工艺实现与冲压件品质的影响也各不相同，因而在冲压模具设计中对机械运动的控制和灵活运用对提高设计水平和保证冲压件品质具有重要意义。

Abstract

Since Dewey developed the concept of “critical thinking”, many scholars abroadhave carried out a series of studies about improving students' critical thinking skills ineducation field. In the 1980s,critical thinking became the target of higher educationprograms in such foreign countries as the US and Canada. It has gained its widespreadattention in China only in recent years. But there are only few studies about it ineducation field. Our traditional English teaching method pays much attention to thetraining of students' linguistic knowledge and language skills but ignores thecultivation of students' critical thinking abilities. In the process of skill practice,teachers often stress the importance of memorizing vocabulary and imitating skillsrigidly,but neglect the students' abilities in analyzing problems and putting forwardinnovative solutions. Therefore, English writing teaching is affected by this andmerely attaches emphasis to train students' reading and writing skills. There are fewstudies which aim at systematically cultivating students' analysis, synthesis, summary,comparison and reasoning skills while they are writing. Therefore,this study aims atdesigning some writings tasks and teaching strategies which can be used to fostercollege students' critical thinking awareness and promote students' all-rounddevelopment.

According to six critical thinking skills,this study was carried out by requiringstudents to hand in an argumentation. All participants in this study are non-Englishmajor college freshmen from a 211 key university. The revised version of Rubric forQualitative Critical Thinking Skills Instrument was used in this study. Withquantitative and qualitative analysis,writing experiment is conducted within a wholesemester to collect data concerning students' learning behavior. Reading-to-write isused in experimental class while traditional method is adopted in control class. Thewriting scores by the experimental and control class were statistically processed bysoftware SPSS . And also the interview was launched in some of students inexperimental class to assess students' critical thinking abilities reflected in theirwritings-The final analysis indicated that EGAP writing model exerted a significantlypositive influence in improving students' critical thinking skills, especially in arousingstudents' writing enthusiasm and critical thinking awareness. Compared with controlclass, students in experimental class made big progress in writing competence. Inaddition, this study put forward some reform proposals to the teaching of Englishwriting. The study is of great value to instruct students to employ critical thinkingskills in their writing.

Abstract

A large body of research has been conducted on the effects of technology-enhancedEnglish vocabulary learning since the 1960s (Marty, 1981)。 However, no consensus hasbeen reached yet (Choo, Lin, & Pandian,2012; Mohsen & Balakumarohsen, 2011)。

Despite the fact that some narrative reviews have evaluated and explored thesecontradictory results, this study aims at quantifying the overall effectiveness oftechnology-enhanced English vocabulary learning with a different approach to review:meta-analysis and performing in-depth moderator analyses of learning method and testtype further.

Totally, twenty effect sizes from thirteen pieces of primary research are obtainedafter collecting related literature published or unpublished in recent ten years via fourchannels and selecting through three filters. Later, all the primary research is coded anddata are computed in random-effects model with software ComprehensiveMeta-Analysis.

Results show that: (1) Technology has a positively large effect on Englishvocabulary learning according to Cohen's standards as proposed in 1992 (g = 95% confidential interval of [, ])。 (2) Learning methods (intentional learning,incidental learning, and integrated learning) have impacts on the overall effectiveness.

Heterogeneity exists in the three learning methods (g = = 0,01 < )，Effectiveness of intentional learning, incidental learning and integrated learning is ^ =, g 二 , g = respectively. Incidental learning under technology-enhancedenvironment yields the largest effectiveness on English vocabulary learning. (3) Testtypes (recognition tests, recall tests,recognition + recall tests) also have impacts on theoverall effectiveness. The three test types are heterogeneous as well {Q = , p = < )。 Recognition tests, recall tests, and recognition + recall tests have effectsizes of and respectively. Technology-enhanced English vocabularylearning achieves the largest effectiveness in recognition tests.

Abstract

The present study, which is based on the Competing Values Framework (. CVF:a framework to identify the organizational effectiveness and to define organizationalculture)， aims to investigate English teachers, teaching motivation at universities, theirperception of the organizational culture in the target university,their professionalaspiration and how they affect each other. The research questions to be addressed are asfollows: (1) How do the English teachers perceive the organizational culture at theirworkplace? (2) How much effort will the teachers pay for their professionalengagement and aspiration? (3) What kinds of motivation do the English teachers in thetarget university appear to have? (4) How will the organizational culture and theprevious experience affect teachers' motivation?

This study employed four different questionnaires as the research instruments,including one demographic questionnaire and three research questionnaires, . thedemographic questionnaire, the Organizational Culture Assessment Instrument (. theOCAI) (Cameron & Quinn, 1999)，the Professional Engagement and CareerDevelopment Aspiration-scale (. the PECDA-scale) (Watt & Richardson, 2008b)，andthe Work Tasks Motivation Scale for Teachers Teaching (. the WTMST) (Fernet et al.,2008)，to investigate the above mentioned research questions. The whole investigationtook roughly 12 weeks and involved three stages: the preparation stage,the pilot study,and the main study.

The findings of the present study show that most of the teachers are intrinsicallymotivated and with identified regulation influenced by the performance culture and theclan culture which are the dominant culture types of the target research site. Results alsoindicate that the overseas experience and length of teaching experience affect teachers'perception of tixe organizational culture and motivation. The participants who haveoverseas experience tend to be more with the sense of professionalism, moreintrinsically motivated and be more confident with their competence in the academicarea; and the ones who have longer years of teaching experience are with moreidentified regulation and introjected motivation and are more committed and moreassured of staying in the education field. The participants in the target universitybasically belong to the highly engaged persisters,and the male teachers expect to be theleadership.

Abstract

Owing to the economic, social and academic needs as well as the advantages of EGAP(General Academic Purpose in Chinese College English) itself, there exist 这 great deal ofnecessity and feasibility for applying English for EGAP class. It is our understanding thatwriting plays an extremely important role in the course of EGAP and genre is a quiteinfluential factor in improving students5 writing competency. However,the investigation ofstudents' current writing situation shows that being deeply influenced by traditional writingteaching methods which emphasize grammar and vocabulary; the students have littleknowledge about genre approach theoretically or systematically and lack the awareness ofgenre. Because of this,it becomes necessary to put forward an English writing teachingapproach which is effective as well as applicable to the situation in China so as to enhancetheir writing competence.

This paper firstly gives a brief introduction to the developing trend of EGAP bydiscussing its necessity and applicability in China and the main views of two schools of genretheory, the tiieoretical foundation and genre-based approaches of three main schools of genrestudy and practice. And also,their characteristics are compared and the adaptability inChinese College EGAP class is analyzed, based on which it puts forward a modifiedGenre-based approach in EGAP writing class in order to enhance students' genre awarenessand improve their writing skills.

To achieve this, two non-English major classes of freshmen in East China University ofScience and Technology (ECUST) have been selected as the experimental class andcontrolled class, and the research lasts one semester. The Genre-based approach is applied inthe experimental class following a modified Genre-based approach. And a comparison hasbeen made on the same subject at the beginning and the end of the semester and thecomparison and contrast between the experimental class and controlled class have also beenmade. Owing to various factors,such as learning motivation, different students show variedextent of acceptance to certain teaching approaches. Therefore, emphasis has not only beenput on the overall changes,but also on the individual differences.

There are three hypotheses:

1. Can Genre-based approach enhance students' genre awareness? 2. Can “genreawareness” really improve students' writing ability in EGAP? If the students can get overallimprovement, is there any difference in gender and the students with diverse learningaptitudes because of the individual difference? If some students fail to improve, what's thepossible reason behind it? 3. Will Chinese students accept and adapt to Genre-basedApproach?

Three sets of data from six writing assignments, writing in final-term examination andquestionnaires are collected and analyzed with the help of the software SPSS . And thestudy indicates that: (1) Genre-based approach has a significant effect in sensitizing students'genre awareness, improving holistic writing competence; (2) during the whole experimentalprocess, girls have a stable superiority over boys, however, boys' improvement fluctuation iscomparatively obvious; (3) students of medium efficiency have the greatest potential to makebig improvement; (4) Unavoidably, in this research there are some students who fail to gainimprovement in terms of writing ability or get changed in terms of writing notions, andthrough analysis it has been found that the main objective reasons are: the difficulty ofwriting itself,the differences of culture and ways of thinking between east and west,thelimited teaching period, etc.; and subjective reasons mainly come from: the limitedcompetence of students themselves, the lack of interest in English writing, etc(5) aoverwhelming majority of students are liable to accept this approach and able to adapt to itpretty well, yet acceptation is not absolutely accompanied by adaptation; (6) feedback is adispensable part in English writing teaching, and more specific feedback will bring strongermotivation in students' self-correcting and developing;In the end,the author presents some limitations in her research and hopes that this cangive some hints and tips to further research in EFL writing classes.

Abstract

In college English listening & speaking classrooms, language and other semioticsystems cooperate together to help students construct meaning. It can be reflected inthe design of textbooks and the use of audios, videos and images, etc. Thus, in thisthesis, the theoretical foundation is the theory of multimodal discourse analysis (MDA)derived from Systemic Functional Linguistics and Social Semiotics. The essence ofMDA is that other semiotic resources such as: images, audios, etc. are as important aslanguage in the meaning-making system. Visual Grammar, Acoustical Grammar andthe integrated frameworks of MDA are the main analysis approaches in this thesis.

Meanwhile, the results of the teaching investigation and the MDA for textbooksare the practical foundation for the multimodal teaching design, providing feasibleand effective suggestions in this thesis. According to the results, it can be concludedthat students have more or less realized multimodality in this course and argue thatmultimodality should be used in moderation; multimodal classroom activities, socialcontent, etc. should be brought into the class; teachers should remind students to payattention to images, fonts change and other multimodal factors in textbooks.

Therefore, when conducting the multimodal teaching design, attention should bepaid to: (1) Modalities influence each other with clear priorities in this course. (2)Words modality and acoustical modality are the primary modalities, while othermodalities are just used as tools to provide supplementary information and to improveteaching efficiency. (3) The chosen modalities should provide supplementaryinformation to make the learning material more easily understood and help studentsconcentrate. Then, on the basis of the above principles and the writer's teachingexperience, a sample teaching design has been worked out, then its' feasibility andeffectiveness have been verified by an empirical study with the method of interview.

Abstract

Degree adverbs play a crucial role in daily language communication. However,owing to their wide varieties and similar meanings, it is hard for language learners toreally master their meanings and usages.

With the aid of AntConc and based on the corpora of FROWN (TheFreiburg-Brown Corpus of American English)，FLOB (The Freiburg-LOB Corpus ofBritish English) and CLEC (Chinese Learner English Corpus)， the study aims tocompare the actual use of common English degree adverbs in terms of semanticprosody between Chinese EFL learners and native English speakers. The researchprocedures consist of two steps. First, AntConc is launched to extractconcordance lines of the target node words in each corpus and the semantic featuresof the node words' collocates are analyzed; then, the semantic prosodies of these nodewords are summarized and comparisons are made between the two corpora.

The results indicate that there are differences as well as similarities betweennative English speakers and Chinese learners in their use of semantic prosody.

Chinese EFL learners tend to underuse the negative semantic prosodies of fairly,highly, and totally?,overuse the negative semantic prosodies of extremely; and misusethe semantic prosody of terribly. The results also show that some problems exist inChinese learners' use of semantic prosodies of degree adverbs, and the reasons mayinclude their first language transfer, intralingual transfer, and the lack of informationabout the semantic prosody in dictionaries and textbooks.
