中國機械技術概況
中國是世界上機械發(fā)展最早的國家之一。中國的機械工程技術不但歷史悠久，而且成就十分輝煌，不僅對中國的物質文化和社會經濟的發(fā)展起到了重要的促進作用，而且對世界技術文明的進步做出了重大貢獻.傳統機械方面，我國在很長一段時期內都領先于世界。到了近代由于特別是從18世紀初到19世紀40年代，由于經濟社會等諸多原因，我國的機械行業(yè)發(fā)展停滯不前，在這100多年的時間里正是西方資產階級政治革命和產業(yè)革命時期，機械科學技術飛速發(fā)展，遠遠超過了中國的水平。這樣，中國機械的發(fā)展水平與西方的差距急劇拉大，到十九世紀中期已經落后西方一百多年。
新中國建立后特別是近三十年來，我國的機械科學技術發(fā)展速度很快。向機械產品大型化，精密化、自動化和成套化的趨勢發(fā)展。在有些方面已經達到或超過了世界先進水平?？偟膩碚f，就目前而言中國機械科學技術的成就是巨大的，發(fā)展速度之快，水平之高也是前所未有的。這一時期還沒有結束，我國的機械科學技術還將向更高的水平發(fā)展。只要我們能夠采取正確的方針、政策、用好科技發(fā)展規(guī)律并勇于創(chuàng)新，我國的機械工業(yè)和機械科技一定能夠振興，重新引領世界機械工業(yè)發(fā)展潮流。上世紀60年代以前，我國小型夯實機械非常缺乏，很多小型場地的夯實基本上采用人工夯實。
上世紀60年代初期，長沙建設機械研究所與北京建筑工程學院等單位合作，在群眾性技術革新成果的基礎上總結發(fā)明了具有中國特色的蛙式夯實機，1962年獲國家科技發(fā)明獎。蛙式夯實機結構簡單，維修、使用方便，很快成為我國60年代夯實機械的主導產品。據不完全統計蛙式夯實機累計產量達到50000多臺，在我國經濟建設中發(fā)揮了重要作用。70年代以后，蛙式夯實機逐漸被性能更先進的振動沖擊夯和振動平板夯所替代，目前蛙式夯實機已經很少，基本被淘汰。
1964年，長沙建設機械研究所開發(fā)了HB120型內燃式夯實機，開始由上海工程機械廠生產，后來主要由津市洞庭工程機械廠生產，年產量200臺左右。80年代，內燃式夯實機產品質量有較大提高，曾出口東南亞和非洲地區(qū)。90年代以后，內燃式夯實機產銷售量也在逐漸減少，目前只有少數小型民營企業(yè)生產。
1977年，長沙建設機械研究所和柳州市建筑機械廠開發(fā)了我國第一臺HZR250型和HZR70型振動平板夯，這兩種產品分別于1979 年和1982年通過了由建設部組織的鑒定。隨后義烏建筑機械廠、四平建筑機械廠、安陽振動器廠、津市洞庭工程機械廠等多家企業(yè)都開始生產振動平板夯。1986年長沙建設機械研究所又開發(fā)了較大的HZR450型振動平板夯。上世紀90年代以后，振動平板夯在我國有了較快的發(fā)展，產品品種、規(guī)格和生產企業(yè)增多，國外的振動平板夯陸續(xù)進入中國市場。
1983年，長沙建設機械研究所和湖北振動器廠聯合開發(fā)了我國第一臺HZR70型振動沖擊夯，1984年通過了由建設部組織的鑒定，1985年獲建設部科技進步三等獎。由于振動沖擊夯具有壓實效果好、生產率高、體積和重量小、輕便靈活等突出特點，深受用戶歡迎，得到了迅速的推廣使用，并很快發(fā)展到資江機器廠、新鄉(xiāng)第三機床廠和津市洞庭工程機械廠等幾十家企業(yè)生產。振動沖擊夯雖然比振動平板夯開發(fā)晚，但發(fā)展速度、產銷量和使用廣泛性比振動平板夯大得多，目前已成為我國夯實機械中產銷量最大的主導產品。上世紀90年代以后，國外的振動平板夯陸續(xù)進入中國市場。
振動沖擊夯和振動平板夯在我國的成功開發(fā)，不僅為我國建設施工部門提供了性能先進的夯實機械，取得了良好的經濟效益和社會效益，而且使我國夯實機械技術向前跨進了一大步，縮短了與世界先進水平的差距，促進了我國壓實機械的發(fā)展。
就機械加工而言：
熱加工 鑄造 據考古發(fā)現，在北京平谷、昌平、房山等處曾出土了公元前16世紀(商代)的青銅禮器。 明永樂年間(1403～1424年)，北京制造出享譽世界的明永樂大銅鐘(46.5噸)和鐘樓大銅鐘(63噸)及鐵鐘(25噸)，采用分爐熔化、地坑造型和陶范法鑄造。 20世紀50年代以前，北京在鑄造上采用粘土砂手工造型。1955年，北京第一機床廠開始采用漏模造型、雙面模型型板及鐵型板和標準砂箱造型。1965年，開始采用塑料模型。 1980 年，北京市機電研究院與北京瑪鋼廠研制成功工頻無芯塞桿底注式保溫澆注電爐。1982年，該院與北京機床鑄造二廠研究成功沖天爐風口吹氧技術。 1985～1988年，北京機床研究所試驗成功浮動端面密封環(huán)的壓力鑄造工藝。
鍛壓 1959年，北京第二通用機械廠(后改名北京重型機器廠)建成2500噸水壓機。1971年，該廠制造出6000噸水壓機，這是當時北京最大的鍛壓設備。 1968～1979年，北京起重機器廠先后采用300噸油壓機和2000噸油壓機制造出起重機吊臂和大型覆蓋件。 80年代，北京市機電研究院和北京市模具中心研制出一系列高精度多工位沖裁模具，接近或達到進口模具水平，改變了北京精密沖裁模具依賴進口的局面。
熱處理 1949年前，北京已采用電爐、鹽溶爐、熱電偶等手段進行零件退火、回火、淬火、正火、調質、滲碳等熱處理。 1956年，北京第一機床廠開始采用高頻感應淬火。1961年，北京第二機床廠開始采用氣體氮化淬火。1969年，北京量具刃具廠開始采用光亮淬火。 1978年，北京機床研究所研究完成機床導軌表面接觸淬火工藝及設備、淬火質量檢查技術條件的研究。1979年，鐵道科學研究院和中國科學院力學研究所等合作完成大功率柴油機缸套表面的激光改性處理的研究。 1979年，北京市機電研究院研制成功千瓦級二氧化碳激光器，并于80年代初分別應用于汽缸套和郵票印刷設備的激光熱處理。其中，清華大學、北京市機電研究院、北京郵票廠共同完成郵票廠七色機打孔器表面激光強化研究。 1984～1990年，北京市熱處理研究所研究成功真空熱處理、氣體滲碳微機控制技術(與北京航空航天大學合作)、稀土軟氮化、粉末冶金制品表面強化、煤油加甲醇小滴量法微機可控滲碳、固體滲硼、滲碳過程微機輔助工藝設計及跟蹤控制系統等熱處理新技術，并應用于生產。 焊接與切割 1949年，北京已有氣焊、電弧焊及氧乙炔火焰切割等手工作業(yè)。 1963年，北京金屬結構廠與一機部機械科學研究院合作開發(fā)出鎢極氬弧焊，并實現了氮氣等離子切割不銹鋼。1964年，用直流鎢極氬弧焊及焊絲合金化技術解決了核工業(yè)用傾斜式電解糟純鎳焊接。 1966年，北京金屬結構廠開發(fā)出了使被焊球體旋轉的埋弧自動焊。1968年，該廠開始以液化石油氣代替乙炔切割。 80年代初，清華大學發(fā)明了新型MIG焊接電弧控制法，在控制電弧技術上取得突破。 80年代初，北京城建設計院等完成液化石油氣移動式氣壓焊軌技術的研究和應用。 1990年，北京金屬結構廠開始采用數控精密切割和具有光電跟蹤及數控尋蹤讀入自動編程的大功率等離子切割技術。

Chinese mechanical engineering technology
China is the world's first national machinery development. Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred years.
After the founding of new China, especially in the past 30 years, our country's mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical industry.
Just small ramming machinery:
In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming.
