Abstract
In the past in coining clearance groove rush of notching machine,electromechanical device was used to control the coining of punch,which had slow speed,great loss,low efficiency. An innovative design was carried out in the PLC control program design to improve efficiency and reduce loss. That is,the new control program is adopted to replace the original clearance mode. New calculation formula and control mode were designed according to the clearance process characteristics. In the new de-sign,the remainder pulse is reasonably distributed and stamping accuracy is guaranteed. The design improved the running speed of notching machine and increased the product qualified rate to 99.3% from original 91.5%. The processing speed increased by 18%. The equipment reliability was improved because some of the electrical and mechanical hardwares got rid of. The reform re-sult shows good PLC program design can completely replace the original hardware control function.关键词
