【摘要】：中国是一个人口大国,也是个农业大国。自从中国农业进入机械化生产开始,国产拖拉机成为农间作业最重要的机械设备,在保证其基本使用性能的前提下,对外观质量和舒适性提出了更高的要求。目前,国内生产的中小马力拖拉机基本没有驾驶室,为露天操作拖拉机,作业环境恶劣。在国家农村生产合作改革下,农业工人对作业环境舒适性的要求不断提升,拖拉机配有驾驶室的比例在不断提升,驾驶室,已经成为100马力以上拖拉机的标配。驾驶室的外观质量影响拖拉机选型购买,电泳油漆的防腐性能直接影响的拖拉机驾驶室使用寿命。国内驾驶室型材主要采用的原材料是热轧板,电泳盐雾性能与欧洲标准存在一定差距。本文对构成驾驶室型材表面进行改进及分析,对拖拉机驾驶室型材表面粗糙度值进行了优化,试验结果验证了本研究优化方法的合理性和有效性。在阐述油漆电泳工艺的过程中,对构成电泳的几个关键要素进行了研究,电泳漆膜厚度对耐盐雾的影响,电泳原材料的表面抛丸情况,漆膜厚度以及相应条件下耐盐雾性能进行分析。最后,根据一拖驾驶室工厂项目的工艺方案先期策划条件,展开了研究和分析,给出了驾驶室整体抛丸,弹丸直径Φ0.6mm,粗糙度6μm以内等工艺技术条件,确定了驾驶室生产标准的先进性,驾驶室工厂按此条件布局规划和建设,驾驶室生产质量水平可达到国内领先水平。
[Abstract]:China is a large population and a large agricultural country. Since China's agriculture began to mechanize production, domestic tractors have become the most important mechanical equipment in agricultural operations, under the premise of ensuring its basic performance. At present, the medium and small horsepower tractors produced in China basically have no cab, operate in the open air, and the working environment is bad. Under the reform of the national rural production cooperation, the paper puts forward higher requirements for the appearance quality and comfort. Agricultural workers' requirements for the comfort of the working environment continue to improve, the proportion of tractors equipped with cab is constantly increasing, cab. It has become the standard of tractor over 100 horsepower. The appearance quality of cab affects the tractor selection and purchase. The anticorrosion performance of electrophoretic paint directly affects the service life of tractor cab. The main raw material of domestic cab profile is hot rolled plate. There is a certain gap between the performance of electrophoretic salt fog and the European standard. The surface roughness of the profile of the tractor cab is optimized by improving and analyzing the profile surface of the cab. The experimental results verify the rationality and effectiveness of the optimization method. In the process of explaining the electrophoretic process, several key elements of the electrophoretic process were studied, and the effect of the thickness of the electrophoretic paint film on the salt fog resistance was studied. The surface shot blasting of electrophoretic raw materials, film thickness and salt spray resistance under the corresponding conditions were analyzed. Finally, the study and analysis were carried out according to the pre-planning conditions of the one-towed cab factory project. The technical conditions such as integral blasting of cab, diameter of projectile 桅 0.6 mm, roughness of less than 6 渭 m are given, and the advanced quality of cab production standard is determined. The layout and construction of cab factory are based on this condition. Cab production quality level can reach the domestic leading level.
