For decades, major manufacturers of sheet-bending machines and folding presses around the globe have been using gearmotors of the renowned Compacta series or custom adaptations based on its principle. Common to all of the drives is a high power density, which is achieved by a compact design with an integrated slide potentiometer, which enables easy activation. The lifting spindle drives of the mini-series or the wide variety of types and sizes from the line of planetary gears by Framo Morat are used in metal processing and machine building.
All standard transmission series are continuously being further developed and improved and serve as an ideal foundation for numerous applications. With appropriate quantities, it is frequently advantageous to design a drive individually in accordance with the required specifications according to the modular principle, or to develop it entirely according to customer specifications. Here, you benefit from Framo Morat’s decades of development experience.
Press brakes are used for bending sheet metal. For this purpose, a bending punch presses the sheet metal into a die which determines the bending angle. Modern press brakes, which are often CNC-controlled, can be used to fold and bend steel sheets several centimetres thick. The multi-axis backgauge used in the planetary gear of the GSA070 series ensures the exact positioning of the plates. This can be controlled to move repeatedly between bends to produce complex parts.
High levels of bending forces in the bending process lead to an elastic deformation of the bending machine’s frame. This results in different bending angles, which leads to faulty workpieces. The crowning unit developed by Framo Morat, which reliably supplies the required adjusting forces, provides the compensation for different bending angles. This development focused on this unit’s ability to be easily integrated into existing control systems. Smooth integration into CNC control systems is ensured using the integrated feedback system.
The Compacta MS12 drives precisely adjust the crowning systems on folding presses (sheet metal bending machines). This compensates for the sagging of the table and press bar.
The Mini linear actuator type 2 is used in a rim production machine.
