The trade of a boilermaker involves handling sheet metal, welding, and operating heavy machinery such as press brakes and shears. The risks are numerous: cuts, burns, entrapments, exposure to fumes, and falls. 3D process simulation offers an advanced solution to recreate these hazardous environments without exposing the worker, allowing each movement to be analyzed and accidents to be anticipated.
Virtual modeling of press brakes and shears to prevent entrapments 🛠️
In a digital twin, we can simulate the operation of a hydraulic press brake. The 3D model accurately reproduces the machine's kinematics, the pinch points, and the trajectory of the sheets. By introducing a human avatar, the exact point where a finger or hand would be trapped if safety distances are not respected is visualized. The same applies to the shear: the simulation shows how improper material placement causes cuts or chip projections, allowing for the design of more effective lockout and signaling protocols.
Training in welding and load handling environments 🔥
Welding exposes workers to toxic fumes and radiation. In the simulator, virtual ventilation can be adjusted, and the operator can be taught to position themselves optimally to minimize inhalation. Additionally, by modeling the lifting of heavy parts, the forces on the spine are calculated, preventing strain injuries. This approach turns risk into an interactive lesson, improving the prevention culture without a single real accident.
How can 3D simulation reduce the risk of entrapment in press brakes and shears during the training of new boilermakers?
(PS: Simulating industrial processes is like watching an ant in a maze, but more expensive.)
