Two different trapping zones
Closing between the punch and die can cause severe injury. A sheet rising or rotating during a bend can also press a hand against the beam or frame. Keeping fingers away from the tooling edge does not necessarily eliminate this second hazard.
Large components may need supports or mechanical handling aids. Where two people work together, the safeguarding and working method must cover both. A control that protects only the person operating it does not resolve a helper’s exposure during the same cycle.
Select and verify the safeguarding
Machine guards, Interlocking devices and presence-sensing devices must be integrated according to the machine’s design and stopping capability. A system fitted to another press brake is not evidence that it suits this one.
Review side and rear access, transmissions and back-gauge movement too. A front sensor can leave hazards outside its field. The foot pedal should be positioned and protected against unintended operation without obstructing the workplace or encouraging an unsafe operating position. The whole working area matters, not simply the line between the tools.
Changes to parts and tooling
A different part length, thickness or bending sequence can change how it is supported and where it moves. Before production, review whether the intended method retains protection throughout the cycle, including removal of the finished component.
Installing heavy tools requires appropriate handling means and a planned intervention. Maintenance, jam clearing and access to hazardous energy require the applicable Lockout/Tagout (LOTO) procedure, including movement and energy that may remain after the machine stops. These tasks must not be treated as ordinary production strokes.
Cuts, checks and operating limits
Sheet edges can cause cuts. Selecting suitable Protective gloves for handling sheet metal does not make gloves protection against crushing or permit hands inside the closing zone.
Record inspections and functional checks, faults and configuration changes. If a component cannot be made with the specified safeguarding in place, stop and review the process with competent personnel. Establish a safe method or choose suitable equipment. Improvising a sensor bypass to finish a batch is not an acceptable response to a production difficulty.
