Problems solved by technology

However, because the flow stress of such high-light materials is greatly affected by temperature, the forging temperature range is narrow, and combined with the characteristics of the size and shape of the hub itself, the traditional forming process is no longer applicable, so special processing and forming methods are required for forming. The parameters of the pressing process have a great influence on the quality of the formed workpiece. The unreasonable selection of the parameters will make the spinning process unstable and cannot be carried out smoothly.

Abstract

The invention discloses a spinning forming numerical analysis method and system. The method includes the following steps of acquiring a spinning numerical analysis model; importing the spinning numerical analysis model into a simulation software; defining the attribution of blank and motion curve of spinning wheels; simulating the spinning numerical analysis model in the simulation software to determine a technological parameter of the wheel hub spinning forming according to the simulation results. The method can provide accurate and reliable the wheel hub spinning forming technological parameter for the wheel hub spinning forming, and accordingly improves the matters that in the process of the wheel hub spinning forming, high reject rate, double heating, product defect and the like causedby high-strength materials characters are improved, and the rate of finished products of the wheel hubs and the efficiency of the finished products are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a numerical analysis method and system for spinning forming. Background technique [0002] Automobile lightweight is the direction of the future development of the automobile industry. Automobile wheels have a large proportion in the whole vehicle, especially in heavy truck models. Therefore, the application of high-strength, light-weight high-light materials on the wheel hub has become the direction of future wheel hub manufacturing. However, because the flow stress of such high-light materials is greatly affected by temperature, the forging temperature range is narrow, and combined with the characteristics of the size and shape of the hub itself, the traditional forming process is no longer applicable, so special processing and forming methods are required for forming. The parameters of the pressing process have a great influence on the quality of the formed workpiece, and...
