The second-generation RAS MiniBendCenter represents a revolutionary advance in production technology for small bent parts. As the world's first fully automatic folding center, it enables the seamless, automated processing of sheet metal: from automatic tool set-up and feeding of the blanks to alignment and measurement. A sophisticated manipulator positions the sheet precisely for the bending process, which can be performed both upwards and downwards.
With the introduction of high-precision servo-electrics, the MiniBendCenter 2 sets new standards in terms of efficiency and precision. The integration of an intelligent robot revolutionizes the loading of punched or laser-cut blanks as well as the unloading of the finished bent parts, which it deposits or stacks unsorted as required. The newly implemented pallet changing station optimizes the material flow by providing a central point for feeding in new blanks and removing the processed parts. With these innovations, the MiniBendCenter 2 not only guarantees low unit costs, but also a quantum leap in productivity in automated sheet metal processing.
A camera system enables the intelligent loading robot to recognize the position of the blanks of a bulk material quantity on a pallet. The software calculates which blanks form the top layer and which parts the robot can access. The robot then picks up one of the available blanks and feeds it to the MiniBendCenter 2.
Of course, the robot can also grip the blanks in stacks. The blanks do not have to lie exactly on top of each other. And the best thing is that the robot does not need to be taught or programmed. Simply start a bending program and the machine does the rest.
The multifunctional vacuum gripper allows different blank geometries to be fed without changing suction cups. Each individual suction cup is programmable and can be controlled separately. Two suction cups are fixed and the position of two suction cups can be adjusted.
The fast and automatic tool changer places the clamping and bending tools into position. Tools not used for a job are stored in the tool magazine. Due to its rotation axis in the gripper, the tool changer can place a tool in the upper or lower clamping beam as well as in the upper and lower folding beam.
The blank scanner measures the exact pick-up position of the blank in the hundredths of a millimeter range. The blank will not be aligned a second time during the bending process.
In the new generation of the MinibendCenter 2, the manipulator clamps, rotates and positions the bent part using high-precision servo-electric drives. As it can even move between the tools, its design opens up an extremely wide range of applications.
The folding beams of the MiniBendCenter 2 can bend the sheet metal flanges up and down. The part does not need to be flipped when the bending direction changes. The workpiece always remains horizontal. There is no need to lift the part as with press brake bending.
The intelligent robot not only loads the blanks, but also unloads the bent parts. The robot knows the position of the provided pallets and unloads the finished parts there. The robot can set up several stacks next to each other.
If the bent parts are not sensitive, the robot can also place them unsorted in a bulk container.
The folded parts are discharged on a short conveyor belt. They drop into a container at the end of the belt
