【摘要】：玻璃模具是玻璃制品成型的重要工具,其质量直接影响本身的使用寿命、玻璃制品的外观和生产成本。等离子焊接(本文主要指等离子喷焊)作为玻璃模具生产中的关键技术在行业中已经取得广泛的应用。然而,玻璃模具等离子焊接工艺却发展缓慢,目前普遍采用传统的手工操作来完成工件上下料、高温预热和等离子焊接等过程,直接导致产品质量一致性差、安全风险高、生产效率低、工作环境恶劣、劳动强度大、高温热害和能源浪费严重等一系列问题。本文对玻璃模具等离子焊接自动生产线进行研究与开发,设计出一套适用于多品种、小批量的玻璃模具等离子焊接生产线,可有效解决目前玻璃模具等离子焊接工艺中存在的问题。论文的主要工作成果如下：首先,分析玻璃模具等离子焊接生产线的技术特点以及功能需求。结合玻璃模具的特点、企业对生产线要求和现有条件,提出本文的设计目标,根据设计目标制定设计方案。其次,对玻璃模具等离子焊接生产线整体机械结构进行设计,完成玻璃模具的自动上料、自动预热、自动送料和焊接下料等工作。机械结构设计包括自动上料机构、转运机构、高效节能加热炉整体结构以及焊接下料机构等结构设计。再次,进行高效节能加热炉整体流-固耦合传热分析和炉门热-结构耦合分析。利用FLOTRAN模块对加热炉整体结构进行流固耦合共轭传热分析来模拟加热炉整体温度场分布的,并以流-固分析结果为基础,进行加热炉炉门结构的热-结构耦合分析及优化,验证改进方案的合理性。最后,基于PLC的自动生产线整体控制系统设计。生产线控制系统可分为硬件电路设计和软件设计,硬件电路设计指各个控制电路模块的设计；系统软件设计是指与控制电路模块相对应的PLC程序设计。
[Abstract]:Glass mould is an important tool for forming glass products. Its quality directly affects its service life, appearance and production cost of glass products. Plasma welding (this paper mainly refers to plasma spray welding) as the key technology of glass mold production has been widely used in the industry. However, the plasma welding technology of glass mould is slow to develop. At present, the traditional manual operation is widely used to finish the process of workpiece loading and unloading, high temperature preheating and plasma welding, which directly leads to poor product quality consistency and high safety risk. A series of problems, such as low production efficiency, bad working environment, high labor intensity, high temperature heat damage and serious energy waste, etc. In this paper, the automatic production line of glass mould plasma welding is researched and developed, and a set of glass mould plasma welding production line suitable for many kinds and small quantities is designed. It can effectively solve the problems existing in plasma welding process of glass mould. The main achievements are as follows: firstly, the technical characteristics and functional requirements of glass die plasma welding production line are analyzed. According to the characteristics of glass mould and the requirements of production line and existing conditions, this paper puts forward the design goal and formulates the design scheme according to the design goal. Secondly, the whole mechanical structure of plasma welding production line of glass mould is designed to finish the automatic feeding, automatic preheating, automatic feeding and welding cutting of glass mould. Mechanical structure design includes automatic feeding mechanism, transfer mechanism, high efficiency energy saving heating furnace integral structure and welding cutting mechanism and so on. Thirdly, the flow-solid coupling heat transfer analysis and the thermal-structure coupling analysis of high efficiency energy-saving reheating furnace are carried out. The fluid-solid coupling conjugate heat transfer analysis of the whole structure of the furnace is carried out by using FLOTRAN module to simulate the whole temperature field distribution of the furnace. Based on the results of the fluid-solid analysis, the thermal-structural coupling analysis and optimization of the furnace door structure are carried out. Verify the rationality of the improved scheme. Finally, the whole control system of automatic production line based on PLC is designed. The production line control system can be divided into hardware circuit design and software design, hardware circuit design refers to the design of each control circuit module, and the system software design refers to the PLC program design corresponding to the control circuit module.
