【摘要】 以全自动注塑成型机为例,将注塑机整体构造及其工作过程移至虚拟环境中,再利用NX软件中的机电概念设计(MCD)模块对注塑机模型进行基本机电对象、信号适配器、外部信号配置和信号映射等设置。S7-PLCSIM Advanced软件作为高级虚拟控制器,是连接MCD模型和TIA博途软件的纽带,通过创建虚拟PLC将博途软件中的PLC程序和MCD模型连接起来,PLC的选型和程序的编写是在博途软件中完成的,最终通过PLC程序来完成注塑机模型工作过程的仿真。该试验为注塑机和其他自动化设备的设计与调试提供了一种思路,能够缩短机电设备设计调试过程中所需要的时间,提高现场调试的效率,降低调试风险,节约成本。对注塑机的整体构造和其注塑过程也进行了充分的分析,有利于对其进一步研究开发。更多还原

【Abstract】 Taking the automatic injection molding machine as an example, the overall structure and working process of the injection molding machine were moved to the virtual environment, and then the electromechanical conceptual design(MCD) module in NX software was used to set the basic electromechanical object, signal adapter, external signal configuration and signal mapping of the injection molding machine model. As an advanced virtual controller, S7-PLCSIM Advanced software was the link between the MCD model and the TIA Portal software. By creating a virtual PLC, the PLC program in the Portal software and the MCD model were connected. The selection of the PLC and the programming of the program were completed in the Portal software, and finally through the PLC program to complete the simulation of the working process of the injection molding machine model. The test provides an idea for the design and commissioning of injection molding machines and other automation equipment, which can shorten the time required for the design and commissioning of electromechanical equipment, improve the efficiency of on-site commissioning, reduce commissioning risks and save costs. The overall structure of the injection molding machine and its injection process have also been fully analyzed, which is conducive to its further research and development.更多还原
