航天阀门是运载火箭压力输送系统的关键零部件，其可靠性的高低将直接影响火箭发射的成败以及相关人员、设备的安全，因此阀门密封结构的品质对于火箭的安全发射极为关键。目前，航天阀门密封结构件的塑性变形滚压成型时在普通车床上通过配备定制滚压刀具的方式完成的。由于加工是人工手动进给，因此不能保证生产节拍和生产效率。文章设计并研制了滚压加工的自动化设备，应用PMAC运动控制卡为核心，结合LabVIEW完成了加工平台的数控系统的编写，并进行了控制系统PID参数调节和传感器的标定。应用该滚压加工平台进行试验加工表明，该加工平台能够实现恒速进给、恒扭矩进给的加工功能，并且能够完成密封结构件的滚压加工，加工后的零件经过检验能够满足密封要求。

Aerospace rocket valve is a key component of the pressure delivery system, its reliability will di-rectly affect the safety of the success of the rocket launch and related personnel, equipment, and therefore the quality of the valve seal structure is critical for the safety of launching rockets. Currently, theroll forming process of sealing partiscompleted by lathe tool with customized tools. Because the process is manually feed, and therefore it can not guarantee the tact and productivity. Designed and developed In this paper, the rolling process automation equipment had been completed, and the control system was been designed by PMAC and LabVIEW. Then the PID parameters of control system were set and the sensors were calibrated. Finally, the seal part rolling finished in the equipment, which indicated this equipment can produce the seal part with the constant feeding rate or the constant torque method, and the quality of sealpart satisfied the design.
