【摘要】：從2002年開始,我國就沒有引進(jìn)過一般水平的普通鋁帶冷軋機(jī),我國鋁帶冷軋機(jī)的設(shè)計、制造水平達(dá)到了一個新的臺階,不僅能滿足國內(nèi)中小企業(yè)的建設(shè),還出口到非洲、南美、中東等國家和地區(qū)。隨著科學(xué)技術(shù)的發(fā)展,鋁帶冷軋機(jī)的技術(shù)進(jìn)步不但體現(xiàn)軋制技術(shù)水平的提高,如設(shè)備機(jī)組在軋制速度、自動化程度等方面的日趨成熟,而且體現(xiàn)在制造技術(shù)水平的提升,如設(shè)備零件的加工、裝配精度的水平,但目前與發(fā)達(dá)國家相比還有一定的差距。在通常的機(jī)械加工制造中,成品的精度要求與軋機(jī)制造水平密切相關(guān)。機(jī)加工零件的幾何精度是零部件的實際幾何形體與理想幾何形體相接近的程度,包括尺寸、形狀、相互位置的精度。零部件幾何精度保證了整機(jī)的裝配精度,決定了整機(jī)的工作精度、可靠性與使用壽命。因此制定合理細(xì)致的機(jī)加工工藝以保證機(jī)加工零件的精度一直是機(jī)械制造行業(yè)的工作重心之一。本文首先對鋁帶冷軋機(jī)機(jī)組的生產(chǎn)工藝進(jìn)行了研究,分析了其中各技術(shù)參數(shù)對質(zhì)量控制的影響,完成了最佳工藝參數(shù)設(shè)計,確定了合理的零件加工工藝方法,并對冷軋機(jī)組中的主要關(guān)鍵零件軸承座、機(jī)架、軋輥進(jìn)行了精度控制分析,對各零件的生產(chǎn)加工工藝內(nèi)容進(jìn)行了研究,確定了保證設(shè)計精度的方法,最后通過實驗,得出了實驗數(shù)據(jù),證明了工藝方法可行、有效。
[Abstract]:Since 2002, China has not introduced ordinary aluminum strip cold rolling mills at a general level. The design and manufacturing level of aluminum strip cold rolling mills in China has reached a new level, which can not only satisfy the construction of domestic small and medium-sized enterprises, but also export to Africa and South America. With the development of science and technology, the technological progress of aluminum strip cold rolling mill not only reflects the improvement of rolling technology level, but also the maturity of rolling speed and automation of equipment units. And it is reflected in the improvement of manufacturing technology, such as the machining of equipment parts and the level of assembly precision, but there is still a certain gap compared with the developed countries at present. The precision requirement of finished product is closely related to the manufacturing level of rolling mill. The geometric accuracy of machined parts is the degree to which the actual geometric shape of the parts is close to the ideal geometric shape, including the dimensions and shapes, The accuracy of mutual position. The geometric accuracy of parts ensures the assembly accuracy of the whole machine and determines the working accuracy of the whole machine. Reliability and service life. Therefore, it is always one of the focus of the machine manufacturing industry to make reasonable and meticulous machining technology to ensure the precision of machined parts. Firstly, the production technology of aluminum strip cold rolling mill is studied in this paper. The influence of each technical parameter on the quality control is analyzed, the optimum process parameter design is completed, the reasonable processing technology method of the parts is determined, and the bearing seat and stand of the main key parts in the cold rolling mill are analyzed. The precision control analysis of roll is carried out, the content of production and processing technology of each part is studied, and the method of ensuring design precision is determined. Finally, through experiment, the experimental data are obtained, which proves that the process method is feasible and effective.
