Overcoming challenges Of 1000T, 1600T, 2000T, 3000T huge press brake bending large sheet metal parts
CNC Synchro press brakes can have some challenges, such as bending sheet angular accuracy, metal material springback after bending and deflection of top&bottom beam, but these are magnified by the sheer dimensions of the metal that these giant machines must bend.
With this situation, more and more press brake tooling manufacture develped a quick die-change upper tool system with rollers that minimizes friction and makes it possible to change large, heavy upper tools within minutes. This tool system can also be complemented with an upper tool holder for storing tools when they’re not in use.
China AHYW Yawei also offers a fully automatic CNC press brake lower die system, the multi-purpose variable bending die tool that adjusts the V opening and has rollers in the bed that make long, heavy bending tooling easy to push in and out of the press brake. Italy Rolleri ROLLA is a fully programmable lower die that can achieve setup reductions of 80 percent or more.
There are also has a non-contact laser angle measurement system that works with an advanced press beam positioning system. When forming high-tensile plates with a high degree of springback, the system can accurately adjust the bend angle, taking into account the springback. No matter the properties or thickness of the material, the system enables an exact determination of the bend angle with an accuracy of better than ±0.3 degrees.
This patented system is active throughout the bending cycle to ensure angular accuracy regardless of material variations and forming conditions.
The sheet angle is measured by scanning the projection of a laser beam to the surface of the sheet metal with a color camera. The angle between the laser and the viewing axis of the camera defines the correlation between the position of the line in the camera image and the angle between the sensor and the sheet. With a second sensor at the opposite site, the bend angle is calculated, it's fully auto setting in DELEM DA66T controller or DELEM DA69T 3D fully touch screen controller.
