一种全电伺服数控折弯机的创新设计

摘要

设计了一种基于连杆机构的全电伺服数控折弯机，它采用伺服电机作为主传动系统的动力源，节能环保、柔性好、速度快、精度高。通过将折弯力在连杆机构内部传导而产生的分力作为补偿力，节省了补偿动力源，具有自适应挠度补偿能力和抗偏载能力。该设计能够为新型数控折弯机的研发提供参考。%A new type of electric servo CNC press brakes based on linkage mechanism is designed .The power source of the main driving system is a servo motor ,which is flexible ,productive and accurate .The flexibility compensation force is the component force of the linkage mechanism as the result of the transmission of the press force .This technology removes the power source of the com-pensation system ,furthermore ,has the capability of adaptive flexibility compensation and anti-deviation .The technical scheme could provide an important reference for the R & D of the model of CNC press brakes .
