Abstract
In this paper, the historical background of press machine is analyzed, and the article literature of various press machines has been read, and the design idea of this design is basically established. The design of this design is the design of the main engine and transmission system of the DP31-250 mechanical press. The main structure of this design is crank slider. Its main design contents include the composition, classification and working principle of the press machine. The movement analysis of the slider, the design and calculation of the eccentric gear core shaft, the selection and determination of the motor, the design of the flywheel, the completion of the design and calculation of the shaft and gear in the transmission system, and the calculation of the force analysis and strength checking of the press, so that the parameters of the components can meet the requirements of the design. It is proved that the structure of each part is reasonable and feasible.
Finally, the design and drawing of 3D solid modeling, assembly drawing and main parts drawing of press are completed by CAD and Creo, and a press and instructions which meet the requirements of the design are designed flexibly with various knowledge, and the design of the press machine is feasible.
