【摘要】：传统花岗石锯解设备不仅很难满足日益增长的市场需求还要受到资源、环保相关政策的约束,新型高效绿色的花岗石框架式锯解设备正是解决此问题的关键。尽管锯解设备已经试制成功,但仍然存在着结构冗余与不合理、设计缺乏理论指导等问题。同时,花岗石大板高加工质量也对锯解设备的性能提出了更高的要求。因此,创新设计锯解设备总体方案并研发承载能力及稳定性出众的导向机构具有重要意义。课题基于模块化设计理论,结合相关行业标准及生产实际,确定了锯解设备的设计原则及加工要求,创新设计一种新型框架式锯解设备总体方案。通过模块化设计,确定各模块、子功能间的能量、物料、信息的传递方式及实现方式,为优化设计锯解滚动导向机构模块的相关结构奠定基础,有助于适应锯解设备谱系化要求、增强市场竞争力。结合框架锯锯解花岗石的载荷特征,提出一种新型滚动导向机构,研究确定了导向机构结构设计参数对其动态特性的影响,为优化导向机构参数、改善导向机构动态特性提供理论基础。通过模态试验,获得锯框各构件前十阶固有频率,并与有限元仿真结果进行对比,得出有限元模型和分析方法的准确性。同时应用ANSYS Workbench的DOE模块对锯框进行轻量化设计,有效降低生产成本。课题功能模块的分析与模块划分的研究为新型锯解设备的研发奠定了技术基础,同时,新型锯解设备的研发将会促进石材行业的绿色生产技术的发展。本课题受到山东省自主创新成果转化专项"石材制品高效绿色生产成套数控装备产业化及示范应用"项目(项目编号2014CGZH0802)和泰山产业领军人才工程"石材绿色高效切割技术及数控设备研发与推广应用"项目经费资助。
[Abstract]:Traditional granite sawing equipment is not only difficult to meet the growing market demand, but also subject to the constraints of resources, environmental protection related policies. A new type of high efficient green granite frame sawing equipment is the key to solve this problem. Although the sawing equipment has been trial-produced successfully, there is still structural redundancy and irrationality. At the same time, the high quality of granite plate also put forward higher requirements for the performance of sawing equipment. It is of great significance to innovate the overall scheme of sawing equipment and to develop a guiding mechanism with outstanding bearing capacity and stability. Based on modular design theory, combining with relevant industry standards and production practice. The design principle and processing requirement of sawing equipment are determined, and a new frame sawing equipment overall scheme is designed. Through modularization design, the energy and material between modules and sub-functions are determined. The transmission and realization of the information lays a foundation for optimizing the design of the relevant structure of the saw cutting rolling guide mechanism module, and is helpful to meet the requirements of the sawing equipment pedigree. According to the load characteristics of sawing granite by frame sawing, a new rolling guide mechanism is proposed, and the influence of structural design parameters of guide mechanism on its dynamic characteristics is studied. This paper provides a theoretical basis for optimizing the parameters of the steering mechanism and improving the dynamic characteristics of the steering mechanism. Through modal tests, the first ten natural frequencies of each component of the saw frame are obtained, and the results are compared with the results of finite element simulation. The accuracy of the finite element model and the analysis method is obtained. At the same time, the light weight design of the saw frame is carried out by using the DOE module of ANSYS Workbench. The analysis of functional modules and the research of module partition have laid a technical foundation for the research and development of new sawing equipment. The research and development of new sawing equipment will promote the development of green production technology in stone industry.
