Can a robot tend a press brake?

This is the deepest integration in the catalog. When it fits it fits very well, and when it does not, no amount of robot solves it.

What the job actually is

An operator loads a blank into a press brake, holds it against the backgauge, follows the sheet up as it bends, then removes and stacks the part. On heavy or awkward blanks it is physically punishing, and on repeat parts it is highly consistent work.

Signs it is worth automating

What the cell looks like

A 20 to 35 kg class arm with sheet grippers, usually a regrip station so the part can be reoriented between bends, and a real interface to the brake controller. The bend sequence, tooling and regrip strategy have to be designed together.

A robotic bending cell, the deepest integration we deal with. The regrip station and the tooling changeover strategy decide whether the project pays, not the arm.

This is one job inside a bigger family. The press brake tending guide covers the equipment classes, the cost ranges, and the disqualifiers for all of it.

When the answer is no

Read this part first

We would rather talk you out of a bad purchase than into one. If any of these describe your version of this job, the honest answer is probably not yet.

What an engineer has to verify

Safety is not on that list because it is not ours to determine. Cell design, guarding and the risk assessment belong to an independent certified integrator, every time.

See it run

Two clips of this job actually running, from two different manufacturers. Both are the makers' own marketing footage, showing a cell under good conditions with a part it was set up for, so watch them for what the motion looks like rather than as evidence of what your rate would be.
