Study On The Cold Milling Machine's Structure Of Milling Device

With the quick development of highway, China request large numbers of milling machines more and more. The cold milling machine is the main equipment for road maintains and preserve. The cold milling machine attach importance to construct company with high quality and efficiency construct impact, more and more cold milling machines are requested to the market.In China, the cold milling machines have huge change in several years, especially 2 meters. Inpersonally speaking, form technique capability, dependability, aspect quality, humanistic design and robotization and so on, the homegrown machinery has a long time to develop. The reason of that is we have a little theory investigation in cold milling machine. Although the cold milling machine's principle of operation is same as rotavator and stabilized solid amalgamator, but they have different operating object. We don't have uniform lodestar for the material of asphaltum concrete, so this text try to analyse the cold milling machine's working principle of operation and disposal of cutting tools and milling movement, set up mathematics model of cutting tools' milling force. Make use of the mathematics model to work out the biggest milling force when cutting tools work at the biggest milling depth, analyse the connection of cutting tools' movement parameter, geometry parameter and milling force, exert computer emulation, educe the rule about cutting tools parameter to cutting tools' milling face in specifically condition. This text is also from the structure and materials for the study to analyse the reason of early abrasion for cutting tools. And it also put forward the milling by the impact of factors affecting productivity, through research to try to maximize the use of milling machines and provide a theoretical basis.The first chapter is the summarize about the cold milling machine, the phylogeny of the cold milling machine in our country and abroad. The second chapter mainly introduces that the cold milling machine's structure of milling device. That includes the working and principle of operation about the cold milling machine, the structure of mantle and the milling drum. The third chapter mainly introduces the analysis of cutting tools'milling force and the affect rual of parameter. The fourth chapter mainly to introduce the cutting tools'disposal of the cold milling machine drum and confirm the cutting tools'geometry angle. The fifth chapter introduces the abrasion of cutting tool and durable of the cold milling machine. The sixth chapter introduces the productivity fact of cold milling machine.
