Research And Design Of The Removable Vehicle For Die Change System In Sheet Metal Hot Forming Processes

Along with our country automobile, aerospace, rapid development of the industry, thesheet metal hot forming parts manufacturing equipment put forward more and more highlydemand, especially because of the domestic aviation enterprise sheet metal hot formingsystem equipment automation degree is low, the supporting facilities is not complete, changemould process is too time-consuming, mould remove way backward, caused the valuemillions of sheet metal hot forming equipment utilization rate is low, which seriously restrictthe sheet metal hot forming system productivity. In view of the above questions, combiningaviation enterprise belongs to the sheet metal hot forming production situation, this paperproposes a high degree of automation under the high temperature of mould and the designscheme of the automatic loading.This paper mainly introduces the mould and loading the overall design, includingmechanical system design, running system design, control system design pole, body center ofgravity balance and heat insulation measures. The mould and loading mechanical systemdesign, the main design L high temperature alloy holding arm, telescopic frame and liftingtable structure, motion accuracy, transmission mode, etc., and to the implement themechanical parts of the mechanical analysis and checking calculation. Mould and loadingrunning system design, including application is a mature AGV technology, according to thejob site planning, select the guide way, walk design route and positioning. Mould and loadingcontrol system design including embedded microcomputer machine as a platform, to realizethe real-time control, drive servo motor, data collection, wireless communication, timelycorrection position deviation value, etc., at the same time include security module, involvingobstacle avoidance of detection system, parking system, alarm system and so on.Finally, by using CATIA and DELMIA software to high temperature mould and loadinga three dimensional geometry model and sheet metal hot forming process simulation toanalyze the motion of the scheme.
