Design And Research Of Automatic Grinding Equipment For Circular Sawblade

With the persistent development of cutting techniques,client’s requirement for circular saw blades are also improving.One of the machining difficulties of circular saw blade is grinding,which have the problems of low production efficiency and unstable machining accuracy.It’s a test for grinding equipment.Therefore,the development of circular saw blade matrix automatic grinding equipment has been one of the hot spots in the industry.Combined with the manufacturers demands,this study analyzed the grinding characteristic of circular saw blade matrix,and adopted the modularization and virtual modeling technology to complete the design of automatic grinding equipment for circular saw blade matrix.On this basis,static analysis,modal analysis,optimization design,prototype preparation test and beat optimization of the machine tool module structure are carried out,which has reduced the product development cycle and laid the root for the product series development in the future.The main contents of this paper are as follows:By analyzing the technological characteristics of circular saw blade substrate structure,the machine tools,grinding tools types and technological parameters of circular saw blade substrate grinding with diameter less than 400mm are determined.According to the standards and manuals,the design requirements of complete sets of equipment for circular saw blade substrate grinding are put forward.The functions of the whole set of equipment are divided modularly by demand analysis,and the combination forms of various modules are put forward.Then the combination scheme is optimized through analysis,and the equipment layout and technical parameters are confirmed in combination with the actual conditions.According to the scheme design,the machine tool function modules such as main motion module,rotary table feed module,machine body module and automatic auxiliary function modules are designed and selected.Then the whole virtual prototype model is output,and the design template is provided,which lays the model foundation for the following finite element optimization analysis of machine tools and the optimization analysis of automatic auxiliary modules.Based on the finite element analysis method,using ANSYS WORKBENCH platform,the static and dynamic characteristics of the whole machine and fuselage components are analyzed in turn to find out the weak links in the design,and the corresponding structure is optimized and improved,and the optimization results are verified.According to the design requirements and the needs of enterprises,the test prototype was prepared,including the overall layout of the design and the workflow planning.About the practice results,from the perspective of lean production,the beat was improved,with 240 pieces per shift being roughly ground and 200 pieces per shift being finely ground,which improved the equipment utilization rate.
