铝型材生产过程的自动化改造

Automation transformation on aluminum profile production process

现阶段我国铝型材生产企业普遍存在着工作环境差、生产效率低、安全隐患多等问题。为了提高铝型材挤压生产效率、降低企业人工成本,对中小型铝型材企业的铝型材挤压成形生产过程的实际工艺流程进行了分析。结合企业现状与现有技术设计了坐标式机械臂、拉伸矫直定位机构、定尺锯切上料机构、自动装框与隔条定位机构以代替人工操作,并对生产线的相关机构进行了调整与优化。结果表明,重新设计优化后的生产线在不大幅度改变现有生产布局的前提下减少人工6名,保证生产过程的稳定性和可靠性,且提高了生产效率。利用Adams对主要功能模块进行运动学仿真验证,在理论层面对机械结构的合理性进行了验证。

At the present stage,there are common problems such as poor working environment,low production efficiency and many safety hazards in aluminum profile production enterprises in China.Therefore,in order to improve the extrusion production efficiency of aluminum profile and reduce the labor cost of enterprise,the actual process flow of aluminum profile extrusion forming production process for small and medium-sized aluminum profile enterprise was analyzed.Then,compared with the current situation of enterprise and the existing technology,the coordinate mechanical arm,positioning mechanism for stretching and straightening,feeding mechanism for fixed-length sawing,positioning mechanism for automatic framing and spacer were designed to replace the manual operation,and the relevant mechanisms of the production line were adjusted and optimized.The results show that the redesigned and optimized production line reduces six labor without greatly changing the existing production layout,ensuring the stability and reliability of the production process,and improving the production efficiency.The kinematics simulation of the main functional modules is verified by Adams,and the rationality of the mechanical structure is verified at the theoretical level.
