[Abstract]:Spinning is a combination of extrusion, stretching, and bending. Plastic forming technology for various forming methods, such as rolling. As a new type of strong spinning forming technology, synchronous rotary die ring spinning technology solves the problem of spinning large thin-walled cylindrical parts on the basis of increasing adaptive tension. Material bulging. Based on the principle of synchronous rotation die ring spinning, the super length of large strength spinning machine is designed according to the machining requirements of large space cylinder parts. The overweight longitudinal feed drive mechanism. This paper focuses on the following content: 1) based on the spinning mechanism of synchronous rotary die ring, the overall layout of the large spinning machine is designed, and. The longitudinal feed drive mechanism of the large strength spinning press is selected and arranged. 2) according to the structure of the selected drive mechanism, the force is studied. The influence factors of deformation provide a theoretical reference for the calculation and selection of the core parameters of the subsequent drive mechanism. Furthermore, the designed drive mechanism is checked and calculated. At the same time, the design calculation of other key parts of the longitudinal drive system is completed.) the vibration model of the drive system is established in this paper. The vibration deformation of the system is analyzed theoretically, and the finite element model of the drive system is established. The mode of the drive mechanism is analyzed by the finite element analysis software ansys workbench, which provides the necessary technical support for the design of the drive system. The finite element analysis model of driving mechanism is established. With the help of finite element analysis software, the static analysis is carried out. The deformation and stress distribution of the driving mechanism under the maximum working load are studied, and the characteristics of the force and deformation are analyzed.
