【摘要】：纤维缠绕的罐形容器由于具有优良的性能,使其广泛地应用于化工、能源、冶金、航天等领域,在国民经济中发挥着重要作用。对于单一大批量罐形容器的生产,结构简单、传动可靠、维修方便、成本低的机械式缠绕机具有较大的优势。本文就是在现有的机械式缠绕机的基础上,结合罐形容器的结构特点,设计一台适用于缠绕罐形容器的机械式缠绕机。机械式缠绕机由小车、床头箱、尾座等组成,主轴带动芯模转动,环链带动小车运动,通过主轴与小车间的传动比,完成罐形容器的缠绕。在缠绕过程中,为了保证缠绕线型的稳定,导丝头与芯模间的距离要保持不变。由于罐形容器筒身段是圆柱体,导丝头在往复运动过程中,与芯模间的距离是恒定的。但罐形容器的封头是椭球形的,为了保证导丝头与芯模间距离的恒定,需要设计一伸臂机构,使其在缠绕封头时推动导丝头前进后退,完成封头的缠绕。本课题的关键就是设计出能完成封头缠绕的伸臂机构。本文是在研究罐形容器的结构特点及对现有缠绕机进行研究的基础上,最终以Pro/E为平台,设计出了缠绕机的小车、床头箱、尾座及伸臂机构,给出了缠绕机的各个零件的结构图,最终建立了缠绕机的三维模型。同时,为了对所设计的缠绕机有直观的认识,能比较真实地反映缠绕机的结构特点及运动过程,检验各个机构是否达到设计要求,以Pre/Mechanism为平台完成缠绕机的机构运动仿真。最后,为了保证缠绕机中零件结构合理可靠,缠绕机能安全地工作,运用ANSYS软件,对缠绕机中重要零件如槽轮,小车底板等进行机构分析,对出现的问题进行修改。
[Abstract]:Because of its excellent performance, fiber winding can descriptor is widely used in chemical, energy, metallurgical, aerospace and other fields, and plays an important role in the national economy. The mechanical winding machine with reliable transmission, convenient maintenance and low cost has great advantages. This paper combines the structural characteristics of the can descriptor on the basis of the existing mechanical winding machine. A mechanical winding machine is designed for describing the winding tank. The mechanical winding machine consists of a small car, a headbox and a tail seat. The spindle drives the core mold to rotate, and the ring chain drives the car to move. Through the transmission ratio between the main shaft and the small workshop, the winding of the can descriptor is completed. In order to ensure the stability of the winding line, the distance between the guide wire head and the core die should be kept unchanged. Because the cylinder section of the can is a cylinder, the guide wire head is in the process of reciprocating. The distance from the core die is constant. However, the head of the can descriptor is ellipsoid. In order to ensure the constant distance between the guide wire head and the core die, an arm extension mechanism is designed to push the guide head forward and backward when winding the seal head. The key of this subject is to design the arm extension mechanism which can finish the winding of the head. Based on the study of the structure characteristics of the can descriptor and the research of the existing winding machine, the car, the headbox, the tail seat and the outstretched arm mechanism of the winding machine are designed on the platform of Pro/E. The structure diagram of each part of the winding machine is given, and finally the three-dimensional model of the winding machine is established. At the same time, in order to have an intuitive understanding of the designed winding machine, it can truly reflect the structure characteristics and motion process of the winding machine. In order to ensure that the structure of winding machine is reasonable and reliable, and the winding function works safely, the software ANSYS is used to verify whether each mechanism meets the design requirements and use Pre/Mechanism as the platform to complete the mechanism motion simulation of winding machine. The mechanism of the important parts of winding machine such as grooves and carts are analyzed and the problems are modified.
