Research And Development Of Numerical Control Double-Ears Rilling Equipment

In this condition, a type of numerical control double-ears rolling equipment is developed, whichcombines the technology of the computer, PLC, machinery, electric and hydraulic. According to the size, theear form, the parameters are prescribed. The rolling method without pull, the automation of more-ears type,the incorporation of double ends calefaction, shearing and bending, rolling are achieved.The research condition of the numerical control double-ears rolling equipment is firstly analyzed, andthen the motion model of the main rolling system is advanced, the problems in the machining course of theleaf spring are analyzed, and the correspond methods are listed to solve these problems. At one time, thestress in the machining course is discussed. Through the high temperature mechanics capability experiment,the changing rule of 60Si2Mn yielding strength with changing of temperature is gained. On this base, thechanging rule of common leaf spring material yielding strength with changing of temperature is summarized.The work principle of the mechanism system is expounded, and the motion project is confirmed, the detailedstructure design of each relate part is completed. The solid drawing of the whole and each part are drawn, thestandard parameter and size of all elements are confirmed. The controlling project is put forward, whichconsist of Industrial Personal Computer and Programmable Logic Controller. The IPC is used to set down andamend the parameters, automatically control, surveillance on line, transmit information and so on, and thePLC is used to incepted information and control the motion of the mechanism system. The design andrealization of PLC controlling software is completed, the serial communication between IPC andC200Hα PLC of OMRON SYSMAC C series is realized with VB 6.0 developing tool. In the end, theconsummation of the whole leaf spring product line is prospected.
