The Design And Research Of Hydraulic Multi-line Natural Stone Cutting Machine

With the rapid development of the construction industry, more and more buildingmaterials is in need, especially the demand of stone, stone plate with its uniquecharacteristics are more and more popular, which has promoted the rapid developmentof stone sawing device. However, there are many problems for the traditional sawingequipment in China, such as backward technology, low outturn percentage and lowautomation, so whether machining accuracy, machine tool structure or productionefficiency can not meet the requirements of modern production.This paper in the full investigation of the existing cutting equipment practicalapplication premise, put forward by diamond cutting technology of cut stone, cuttingwith cutting narrow slits, material saving, cut stone will not cause the break, do notcause dust, pollution is little wait for an advantage, in the stone cutting field will beused more and more widely.First of all, the paper presents a method of overall design scheme of hydraulicmulti-line natural stone cutting machine, and complete the detailed structural design ofit. CAD/CAE technology has been used in the design, a three-dimensional model ofhydraulic multi-line natural stone cutting machine is established by Pro/E, which makeit materialized, visualization, short the design cycle and improved work efficiency.Secondly, based on theory of finite element analysis, the paper uses ANSYSsoftware to analyze the key parts and the machine in order to verify the design ofrationality and reliability, and provides a theoretical for optimizing calculate thestrength and stiffness, while the use of large safety factor while led to institutionsaffected by heavy machine dynamic performance.Finally, this machine adopts full hydraulic transmission technology, the maincampaign tool replaced by the hydraulic motor gear box, the tensioning device adopts ahydraulic spring, uses the hydraulic cylinder to control table feed speed of machinetools is realized, variable speed regulation, smooth transmission, low cost, convenientoperation and so on.After the success of new hydraulic multi-line natural stone cutting machine researched will satisfactorily resolve the problem of processing large format or ultra-large-format stone plate products. At the same time processing efficiency will furtherpromotion. The new cutting equipment will have high economic and wide prospectmarket, which open a new direction for this kind of machine tool development.
