Title Design of Sheet Feeding Mechanism for Large Milling Machine

Abstract

At present, the feeding operation of the domestic milling machine is mainly done by manual operation, the production efficiency is low, the labor intensity is large, the work environment is bad, and the safety hazard is large.. This project is based on the cooperation project, CNC milling steel plate for large sheet groove processing machine design auxiliary feeding device. This mechanism is reasonable, easy to manufacture, easy to operate, and can not only finish the feeding work of the milling machine, but also can change the components to the milling edge machining of different size sheet..

In this paper, the development status and trend of the feed mechanism of the mill is firstly introduced, and the overall design scheme is determined by the analysis of the milling edge machining and the machining requirements.. After the completion of 3D modeling, the finite element analysis is used to analyze the linkage mechanism and verify its rationality..

Through the design, the plate feeding structure design and reliability analysis of the feeding mechanism, is a certain significance of milling processing auxiliary operation improvement, optimization and innovation of the has a certain significance.
