【摘要】：新型整体成型排气道为内圆外方的结构，相比于传统的内方外方结构的排气道，它的通风性能更好，结构强度更高，具有较大的市场前景。新型整体成型排气道的自动化生产线是用于大批量生产新型整体成型排气道的关键的设备，可以有效的提高排气道的生产效率、提高企业的经济效益和节省工人的劳动力。本文就新型整体成型排气道的自动化生产线的设计进行了研究。首先分析了新型整体成型排气道的结构、材质，然后提出以模具作为排气道大批量生产的主要装备，在此基础上进一步进行了脱模力分析、水泥砂浆的浇注性能分析、生产线的工作流程分析等。再根据上述分析，提出二套自动化生产线的总体设计方案并进行对比以选出最优方案。由整体设计方案将生产线分为5个模块：模具、模具浇注系统、排气道脱模系统、模具输送线、PLC控制系统。然后用Pro/ENGINEER软件为各个模块建立了各自的主要零部件模型，对各模块的标准件进行了计算、选型，建立各功能模块的数字样机。对主要的模具模块进行添加材料属性、驱动属性、约束属性并进行了运动分析及仿真，，验证了模具机构的各项功能并对模具中的关键零件进行了有限元分析及优化。最后了设计生产线的PLC控制系统及梯形图程序并给出生产线的总体结构图。本论文主要工作集中在机构设计与结构优化、运动学分析与仿真和自动化控制三个方面，所设计的生产线有很大的实用价值，在设计过程中所用的方法和思路对其他机械设计有一定参考价值。
[Abstract]:A new integral forming exhaust structure inside the circle, the exhaust passage inside foreign structure compared to the traditional, its better ventilation structure, higher strength, greater market prospects. Automatic production line of the new integrated exhaust equipment for the production of new key is integrally formed exhaust mass an effective, can improve production efficiency, improve the economic efficiency of enterprises and workers to save labor.
This paper makes a study of the design of automatic production line of the new integrated exhaust duct. The paper introduces the structure, the overall model forming an exhaust passage of the material, and then put forward to die as the main equipment exhaust mass production, further the demoulding force analysis, analysis the casting properties of cement mortar, production line the work flow analysis. According to the above analysis, put forward two sets of automatic production line of the overall design scheme and compared to select the optimal solution. The overall design of the production line is divided into 5 modules: mold, die casting system, exhaust ejection system, mold conveying line, PLC control system and using the Pro/ENGINEER software. For each module to establish the main components of the respective models, each module of standard parts are calculated, selection, establishment of digital prototype of each functional module. The main module A module to add material properties, drive properties, analyze and simulate the motion constraint and attribute, verify that the function of the mold mechanism and finite element analysis and optimization of key parts of the mould. Finally, the overall structure of the design of the production line PLC control system and program and gives the production line.
In the mechanism design and structure optimization on the main work of this paper, the kinematics analysis and simulation and automatic control of the three aspects of the design, the production line has great practical value, the methods and ideas used in the design process has a certain reference value for other mechanical design.
