Adaptive bending system for robotic bending cell
- November 26, 2019
The LVD Strippit Dyna-Cell robotic bending cell is now available with LVD’s Easy-Form Laser in-process adaptive bending system.
Easy-Form establishes the desired angle from the first bending operation. Dyna-Cell also features a new intelligent automatic programming wizard for programming the bending cell.
LVD Strippit says these features advance Dyna-Cell’s capacity to automate the bending of small- to medium-sized parts in varying batch sizes at bending speeds up to 25 mm (1 in.)) per second.
LVD’s 10-10 rule means that CAM generation of the bending and robot program takes 10 minutes and setup and first part production takes the same amount of time.
Dyna-Cell is equipped with an intelligent automatic programming wizard. CAM program preparation of the press brake and robot is handled offline with no need to physically teach the robot. This cuts setup time and speeds up ‘art-to-part’ times for batches of all sizes.
After importing the 3D drawing, the software automatically generates the bending and robotics program. The software calculates a complete collision-free path through all positions, while also providing easy programming of “standard” product families, such as multi flange, brackets and profiles.
The software automatically generates the press brake bending program and the robot’s movement, directing it from one bend to the next to form the part and then to offload or stack the part.
LVD’s Easy-Form Laser adaptive bending system adds process consistency to Dyna-Cell. Easy-Form is an option on the Dyna-Press Pro 40-ton electric press brake that is at the heart of the Dyna-Cell. Easy-Form transmits the digital information in real time to the CNC control unit, which processes it and adjusts the position of the ram/punch to achieve the correct angle. The bending process is not interrupted and no production time is lost. Easy-Form allows the machine to adapt to material variations, including sheet thickness, strain hardening and grain direction, automatically compensating for changes.
Dyna-Cell is designed to work in automated bending mode or as a standalone press brake when the application does not warrant automation.
A patent-pending universal gripper handles a wide range of parts, eliminating the need for different-sized grippers and reducing part regripping and changeover time. LVD’s universal gripper accommodates part sizes from 35 X 100 mm (1.37 X 3.93 in.) up to 350 X 500 mm (13.78 X 19.68 in.) and manages parts as heavy as 3 kg (6.6 lbs.).
The Dyna-Cell compact bending cell has a footprint of 5 X 5 m (16 X 16 ft.).
