The Anerka KR-4 2050-230 is a four-roll plate rolling machine designed for precision bending of sheet metal. Manufactured in 2023, this robust machine features four large cylindrical rollers with diameters of 230 mm for the upper roll, 210 mm for the bottom roll, and 190 mm for the side rollers. It supports a working length of 2050 mm and can handle maximum sheet thicknesses of 10 mm for Ødx1.5, 13 mm for Ødx3, and 15 mm for Ødx5 materials. The machine's maximum distance between rollers is 30 mm, with a maximum passage thickness of 25 mm. Power is supplied by an 11 kW engine operating on a 3x400V / 50Hz power supply.
The rollers are made from high-grade carbon steel CK50 and are inductively hardened to a hardness of HRc 56±4. Roller bearings include spherical roller bearings and bronze plain bearings, ensuring durability and smooth operation. Drive is transmitted to two rollers—the central and lower rollers—via planetary gears. Roll positioning can be manually calibrated, with electronic synchronization available in the optional NC-CNC version. The locking pressure of sheet metal between rollers is adjustable through a hydraulic pressure system.
This machine measures approximately 3860 mm in length, 1160 mm in width, and 1180 mm in height, with a working height of 825 mm. It weighs around 4600 kg and contains 160 liters of oil in the system. The bending speed reaches up to 5 m/min.
Additional features include a standard PLC control system, with an optional NC-CNC upgrade available. The machine supports manual cone bending as a standard function and requires manual roller bearing lubrication, though an automatic lubrication system is recommended for the NC-CNC version.
The equipment includes a control panel with a display screen and buttons mounted on a separate stand connected to the machine by a cable, facilitating user operation. A vertical support structure with a red horizontal arm is positioned above the rolls, and a safety guard or protective bar is installed in front of the rollers to enhance operator safety. The brand name "ANERKA" and logo are prominently displayed on the machine.
