【正文】 wing implementation , the overall requirementsCounty county education practice to the eighteen Party of eight, the spirit of the the third Plenary Session of the 18th CPC Central Committee as the guidance, conscientiously implement the spirit of general secretary Xi Jinping book series of important speech, earnestly implement the Central Committee really, opinions and advice , party implementing the guiding ideology of opinions to determine the objectives and requirements, step method, in accordance with the look in the mirror, dress up, wash bath, cure treatment, the general requirements of for the people pragmatic honest people as the theme, in carrying forward the spirit of Zhuanglang Zhuang, improve their work style, service to the masses of the people, the foundation of consolidating grassroots, promote transformation across efforts, to further implement the central eight regulations and The opposition party and government austerity waste regulations , double section provincial regulations, municipal provisions of the twelve plan and the implementation measures for on improving the work style of close ties with the masses law, highlight style building, carry out the whole wind spirit, resolutely oppose formalism, bureaucracy, hedonism and wasteful extravagance to solve the problems, Party members and cadres of the style and the masses of people strong, the Ministry of Party members and cadres to further improve their thinking and understanding, to further change the style of the wind, the masses to close, honest and pragmatic people honest image to further establish the foundation to further reinforce the basic level. Style of the building of the new results to promote the construction of a powerful force of the county and the ecological culture of the county and county educational practice activities of the unit is mainly: the county and below county departments under the organs, enterprises and institutions directly under the township, street, and munity, village, nonpublic economic organizations, social organizations and other grassroots organizations. Agencies and branches, each single unit, follow the rules on internal institutions. Educational practice with step by adhere to the county leadership, leadership and leading cadres to focus on outstanding catch to directly contact the service of the masses of law supervision departments and window units, service industry, educational practice, pay attention to grasp the heavy towns, streets and villages, munity education activities and the masses of grassroots groups in close contact to strengthen, and the majority of Party members, cadres and the mass line line Marx doctrine view of the masses and the party39。s implementation opinions, the spirit of the party39。報告格式請參照“畢業(yè)論文（設(shè)計）”格式。05應用文獻的能力5能獨立查閱相關(guān)文獻和從事其他調(diào)研；能提出并較好地論述課題的實施方案；有收集、加工各種信息及獲取新知識的能力。低合金冷作模具鋼俗稱油淬鋼，主要是GB 1299標準中的低合金工具鋼，用于非合金工具鋼淬透性不足，模具零件淬硬層淺或淬火變形較大的情況下取代非合金工具鋼的場合。還具有中等程度的脫碳敏感性，加熱時應采取防護措施。C，等溫退火的等溫溫度680~710176。①過載失效這是由于模具零件材料及其熱處理后本身存在能力不足以抵抗工作載荷作用而引起的失效。在交變載荷作用下，達到一定的沖擊次數(shù)(多發(fā)生在1000～5000次)后，模具零件萌生微小裂紋(疲勞源)，裂紋不斷擴展后發(fā)生斷裂而導致失效。屈服點是衡量模具零件塑性變形抗力的指標，也是最常用的強度指標。3攀枝花學院本科課程設(shè)計（論文） 2 設(shè)計方案低合金刃具鋼9Mn2V是利用我國豐富的錳、釩資源研制出來的不含鉻的冷作模具鋼。9M2V鋼屬于高碳鋼，. 9Mn2V鋼的化學成分（質(zhì)量分數(shù)，%）CSiMnV～≤40～ ～ 成分分析：9Mn2V模具鋼中含有一定量的釩，細化了晶粒，減小了過熱敏感性, 具有較高的硬度和耐磨性，淬透性很好，淬火時變形較小9Mn2V鋼的淬透性接近9SiCr鋼，低于CrMn鋼；回火穩(wěn)定性甚差，幾乎與碳素工具鋼相近, 總的來說，碳化物量比CrMn鋼要少，但顆粒度較大，因此耐磨性不及CrMn鋼，但仍比T10鋼的耐磨性要高6～7倍。在實際的生產(chǎn)中，有的采用調(diào)質(zhì)處理球化處理的方法，溫度在A c。在選取回火溫度時，應該注意避開回火脆性區(qū)，常用鋼的回火脆性溫度如下：9Mn2V鋼為190℃～230℃。主要包括各種方法的淬火、回火和冷處理以及化學熱處理等表面強化技術(shù)。，必要時用磁力，滲透等探傷手段檢查。+ 121200+ + 210300+ + 模具各種孔中心距變形率（%）177?？捎美锸嫌捕葍x對大型
