In research, the high failure rate of indigenously produced mold die of an industrial punching machine utilized for the production of cable trays was investigated. This was aimed at discovering the reason(s) for the disparity in the service life of the indigenously produced die as against the imported ones that had a longer service life.
Big press brake bending, high throughput.It’s tough for a press brake department to keep up when jobs coming through are for small quantities, each requiring tooling changeover time.
Better bump radius bending.The chapter on bump radius bending, excerpted here, explains how to calculate the best approach for your large-radius bend without employing special tooling.
Years ago an operator might install a single punch and die set on a press brake and keep that tooling setup for days, even weeks. It exemplified the traditional view of production efficiency at its finest.
Over the past three decades, as press brake technology evolved, precision bending evolved with it. In the early 1970s, bottoming with penetration with a mechanical press brake was the only way to attain a bend ±1 degree.
