Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli. It is also the joint of the four prairies across the SinoMongolian border, where people gravitate towards the exotic atmosphere mixed with Chinese, Russian, and Mongolia elements. As a historic site for the Yitian Battle, Arxan still embodies the spirit of Genghis Khan. Walking into Arxan, you will be amazed by a kaleidoscope of geous colors all the year round the Spring azaleas blooming red in the snow, the Summer sea wavering blue in the breeze, the Autumn leaves painted in yellow covering volcanic traces, and the Winter woods shining white on the vast alpine snowscape. Hinggan League Arxan city is situated in the far eastern area of Inner Mongolia Autonomous Region. Its full name Haren Arxan means hot holy water in the Mongolian language. Arxan is a tourism city in the northern frontier with a blend of large forest, grand prairies, vast snowfield, heaven lake cluster, thermium, as well as volcanic cluster. It is a rare and unique ecotourism base filled with healthy sunshine, clean air and unspoiled green. Nestled close to the country39。 Festival. In this day, girls will throw a sewing needle into a bowl full of water on the night of Qixi as a test of embroidery skills. If the needle floats on top of the water instead of sinking, it proves the girl is a skilled embroiders. Single women also pra y for finding a goo。s time for the wild fruits to ripe. The picturesque Arxan in Autumn is indeed a fairyland only exists in a dream that satisfies all your fantasies. If it rains heavily on Saturday night, some elderly Chinese will say it is because Zhinu, or the Weaving Maid, is crying on the day she met her husband Niulang, or the Cowherd, on the Milky Way. Most Chinese remember being told this romantic tragedy when they were children on Qixi, or the Seventh Night Festival, which falls on the seventh day of the seventh lunar month, which is usually in early August. This year it falls on Saturday, August 2. Folklore Story As the story goes, once there was a cowherd, Niulang, who lived with his elder brother and sisterinlaw. But she disliked and abused him, and the boy was forced to leave home with only an old cow for pany. The cow, however, was a former god who had violated imperial rules and was sent to earth in bovine form. One day the cow led Niulang to a lake where fairies took a bath on earth. Among them was Zhinu, the most beautiful fairy and a skilled seamstress. The two fell in love at first sight and were soon married. They had a son and daughter and their happy life was held up as an example for hundreds of years in China. Yet in the eyes of the Jade Emperor, the Supreme Deity in Taoism, marriage between a mortal and fairy was strictly forbidden. He ordered the heaven troop to catch Zhinu back. Niulang grew desperate when he discovered Zhinu had been taken back to heaven. Driven by Niulang39。 我非常慶幸在三年的的學(xué)習(xí)、生活中認(rèn)識(shí)了很多可敬的老師和可親的同學(xué)，并感激師友的教誨和幫助。 引線片沖裁件沖裁工藝及模具設(shè)計(jì) 29 致 謝 首先感謝本人的導(dǎo)師翟德梅老師，她仔細(xì)審閱了本文的全部?jī)?nèi)容并對(duì)我的畢業(yè)設(shè)計(jì)內(nèi)容提出了許多建設(shè)性建議。 沖壓模具設(shè)計(jì)則是依據(jù)制定的沖壓工藝規(guī)程，在認(rèn)真考慮毛坯的定位、出件、廢料排出諸問(wèn)題以及模 具的制造維修方便、操作安全可靠等因素后，設(shè)計(jì)計(jì)算并構(gòu)思出與沖壓設(shè)備想適應(yīng)的模具總體結(jié)構(gòu)，然后繪制出模具總裝圖和所有非標(biāo)準(zhǔn)零件圖的整個(gè)設(shè)計(jì)繪圖過(guò)程。 通過(guò)這次設(shè)計(jì)，我更加深入地學(xué)習(xí)了冷沖壓技術(shù)工作設(shè)計(jì)的內(nèi)容。特別是原來(lái)所學(xué)的一些專(zhuān)業(yè)基礎(chǔ)課：如機(jī)械制圖、模具材料、公差配合與技術(shù)測(cè)量、冷沖模具設(shè)計(jì)與制造等有了更深刻的理解，使我進(jìn)一步 的了解了怎樣將這些知識(shí)運(yùn)用到實(shí)際的設(shè)計(jì)中。 河南機(jī)電高等專(zhuān)科學(xué)校畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 28 設(shè) 計(jì) 總 結(jié) 本畢業(yè)設(shè)計(jì)是我進(jìn)行完了三年的模具設(shè)計(jì)與制造專(zhuān)業(yè)課程后進(jìn)行的，它是對(duì)我們?nèi)陙?lái)所學(xué)課程的又一次深入、系統(tǒng)的綜合性的復(fù)習(xí)，也是一次理論聯(lián)系實(shí)踐的訓(xùn)練。不合適者應(yīng)重新修磨或更換。 河南機(jī)電高等專(zhuān)科學(xué)校畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 22 圖 5引線片級(jí)進(jìn)模裝配圖 凹模 螺釘 導(dǎo)料板 彈性橡膠體 導(dǎo)套 螺釘 下模座 模柄 止 轉(zhuǎn) 銷(xiāo) 銷(xiāo)釘 1墊板 1導(dǎo)柱 1 凸模固定板 1 螺釘 1卸料板 1側(cè)刃切刀 1銷(xiāo)釘 1 螺釘 下模座 引線片沖裁件沖裁工藝及模具設(shè)計(jì) 23 7 模具零件加工工藝 本副沖裁模，模具零件加工的關(guān)鍵在工作零件、固定板以及卸料板，若采用線切割加工技術(shù)，這些零件的加工就變得相對(duì)簡(jiǎn)單。模具上模部分主要由上模座、墊板、凸模（ 8個(gè)）、凸模固定板及卸料板等組成。 : 與 橡膠壓縮量有關(guān)的單位 MPa,查表 878[7]壓縮量取 30%， p?。? （ 2）橡膠的高度尺寸 使用橡膠時(shí)，不應(yīng)使最大相對(duì)壓縮量過(guò)大，避免橡膠過(guò)早失去彈性而損壞，其允許最大壓
