Structure Design And Simulation Analysis For Transmission Mechanism Of Two-point Servo Press

As an important processing equipment, the stamping equipment and its rigid processing production line are difficult to meet the requirements of modern industry with regard to processing flexibility, processing accuracy and processing quality, under the background of that production model is changing into multi-varieties and small-batch production. Intelligent stamping equipment which has strong controllability, high automatization and processing adaptability is badly needed in some related manufacturing field. As a new generation of stamping equipment, the servo press which uses high power ac servo motor as power supply, which not only maintains the advantages of mechanical transmission, but greatly improves the processing flexibility and adaptability of the equipment. Moreover, the machining precision and machining quality of the product are improved. The servo press satisfies the requirements of relevant industry and has obtained great promotion and application in related field.In this paper, according to the design of a 5000 KN servo press, the optimization design of no-flywheel transmission system is studied. On this basis, a main transmission mechanism structure design scheme of 5000 k N servo press is proposed. Furthermore, a virtual prototype model of the scheme is established and the machine dynamic performance of the system is studied combining with the different servo press machining modes and characteristics, the machine dynamic performance of the system is analyzed. The main research content of this article is organized as follows:First, the kinematics and dynamics characteristics of a composite transmission system is analyzed, and the mathematical model of the organization is established. The results show that the composite power transmission mechanism can significantly reduce the motor torque. At the same time, the fluctuation of the slider velocity in processing travel is smaller compared with the traditional crank slider mechanism, which can help improve the forming quality of machining.Second, the parameterized simulation model of the power transmission system is set up, the influence of the system’s output performance in the condition of different structure parameters combination are discussed. According to the design requirements, the optimal design parameter combination is given eventually. Furthermore, with the help of 3D CAD software, the components of the transmission are designed and assembled. Compared with the traditional design of the servo press, the overall stress distribution of this design is more reasonable and the ability of press load and partial load resistance are enhanced.Third, combined with experimental data of the virtual prototype, the strength check of carrying parts in this double point servo press is carried out using finite element analysis software ANSYS. In addition, with the help of ANSYS Design Xplorer optimization function module, the geometric feature parameters of important components are further optimized, ensuring structure stiffness and strength and saving equipment production costs.Finally, the virtual prototype model of the double point servo press is established by using multi-body dynamics software ADAMS. Furthermore, the data of motor speed and torque under different working mode are observed through the reverse way. Therefore, the control parameters of servo motor are observed through this way.
