[Abstract]:Aiming at the influence of mechanical press braking performance on its safety performance, the testing technology of mechanical press braking performance is studied according to the standard, and a mechanical press braking performance testing system based on virtual instrument is put forward. The system adopts the rotating state of the crank shaft of the incremental photoelectric encoder induction press and the emergency brake switch state of the Hall sensor. The LabVIEW software based on the virtual instrument technology is used as the programming tool. A set of testing software for brake performance of mechanical press is designed. The testing of brake response time and crank braking angle of press is realized, and the theory and example are verified in the actual testing of press. The research results show that the system can accurately detect the braking response time and crank braking angle of the press, and this scheme can effectively reduce the programming workload, improve the reliability and stability of the system, and evaluate the braking performance of the press. The safety protection performance provides the reliable guarantee.
