【摘要】：DMC复合材料广泛应用于各个行业,如信号盒外壳、车厢窗框、窨井盖等等。根据公司生产要求,本文设计研发一套DMC复合材料混合自动生产线。本文对DMC复合材料混合生产工艺进行了详细分析研究,大致分为搅拌工艺、送料工艺和捏合成型工艺。搅拌工艺包含固液搅拌和液液搅拌。液液搅拌的溶液粘度较高,采用框式桨叶。固液搅拌是聚苯乙烯粒子在苯乙烯中的搅拌溶解,耗时较长。搅拌器类型及工作形式对整个搅拌效率影响至关重要,通过ANSYS数值模拟和试验论证,研发出有利于固液搅拌混合的搅拌器类型及工作形式。最终,选取四块挡板均布,三层六折叶开启涡轮式搅拌器对中搅拌。送料工艺主要包括对石粉和玻璃纤维这两种特殊物料进行输送,要求高度自动化、精确配料、高效运输等。为此,设计研发出石粉塔加料机构、玻璃纤维投料机,能够实现自动配重且加料,按时间要求合理控制加料时间、加料量。捏合成型工艺主要是对捏合机的选型,并加以改造,使其符合整套生产线;为满足企业要求获得DMC复合材料形状,设计成型装置。针对各工艺要求,设计研发机构,并通过Solidworks软件对整个生产线进行实体建模,计算时间节拍,优化设计,完善生产线装置的结构、布局,使之符合生产要求。DMC复合材料自动化生产线的实施,可有效提高产品质量和生产效率,并改善劳动环境及减轻劳动强度,这对企业长远发展及经济效益具有重大意义。
[Abstract]:DMC composite materials are widely used in various industries, such as signal box housing, car window frame, manhole cover and so on. According to the production requirements of the company, this paper designed and developed a DMC composite material hybrid automatic production line. In this paper, the mixed production process of DMC composite is analyzed in detail, which can be divided into mixing process, feeding process and kneading process. The mixing process includes solid-liquid stirring and liquid-liquid stirring. The solution viscosity of liquid-liquid stirring is high, and the frame blade is adopted. Solid-liquid stirring is the stirring dissolution of polystyrene particles in styrene, which takes a long time. The type and working form of agitator are of great importance to the whole agitation efficiency. Through ANSYS numerical simulation and experimental demonstration, the type and working form of agitator are developed in favor of solid-liquid mixing. Finally, four baffles are evenly distributed and three layers of 40% discounted blades are opened to center the turbine agitator. The feeding technology mainly includes two kinds of special materials, stone powder and glass fiber, which require high automation, accurate proportioning, high efficiency transportation and so on. Therefore, the design and development of the stone powder tower feeding mechanism, glass fiber feeder, can achieve automatic weight and feeding, according to the time requirements of reasonable control of the feeding time, feeding quantity. The kneading process is mainly to type the kneading machine and make it fit the whole production line. In order to meet the requirements of the enterprise to obtain the shape of DMC composite material, the molding device is designed. According to the process requirements, the research and development organization is designed, and the whole production line is modeled by Solidworks software, the time beat is calculated, the design is optimized, and the structure and layout of the production line device is improved. To make it meet the requirement of production. DMC composite material automation production line can effectively improve the product quality and production efficiency, and improve the labor environment and reduce labor intensity, which is of great significance to the long-term development and economic benefits of enterprises.
