PLANETARY GUIDES Various types of profiles are easily rolled with the power applied from side rolls while pinched between top and bottom rolls. The side rolls are driven by hydraulic cylinders which are the main source of the rolling power. Since the side rolls approach to the top roll with a slightly wider angle, less power is consumed for the same unbent flat ends, thus saving energy. The planetary guiding system therefore provides excellent pre-bend with less power. ROLLS The shafts and rolls on the APK machines are made of 42CrMo4 alloyed steel. The rolls are also induction hardened between 50-55 HRC and polished proving high quality of materials used. The bigger roll diameters enable the APK series have minimum flexion and hence less deformation. Beside employment of bigger size bearings also results in longer product life. BEARINGS All the rolls are supported with roller bearings. The roller bearings are suitable for carrying very heavy loads. The roller bearings operate with high precision even under difficult working conditions and are long lasting. Thanks to the use of rolling bearings, friction forces are reduced and thus energy is saved. This means that the drive force is not reduced by the frictional forces, but the whole power is used to shape the material. BODY STRUCTURE The frames of these Angle Rolls are designed to obtain a maximum strength and rigid structure. In this way, tensions that occur during bending are minimized to provide safer and longer machine life. The bodies of these Angle Rolls consist of certified St-52 quality steel construction. CONTROL PANEL Because of its mobility, it is possible to control the rolling process from all sides of the machine. On the digital display offered on the standard machines, values of present and the maximum positions of the right and left rolls are displayed. In addition, the number of control buttons in the control panel can be increased according to the preferred optional features. DIGITAL DISPLAY The digital display shows positions of the bottom rolls. The upper positioning limits of side rolls can also be adjusted. This way, it can be ensured that the side rolls do not go beyond the maximum position. MANUAL GUIDE ROLLS The manual guide rolls are provided as standard. The guide rolls are adjustable manually in one direction. HYDRAULIC SYSTEM The hydraulic system is designed to carry out all the movements of the machine. The hydraulic tank is isolated from the outside to keep the oil clean. The return filter (pressure filter if necessary) ensures that the oil remains clean. The piping system is designed to create minimal pressure loss, to be easily dismantled and to provide the best possible leak-tightness. The hydraulic protection system against overloads ensures keeping the hydraulic pressure at a safe level and provides safety. ELECTRICAL SYSTEM The power circuit and the control circuit are isolated from each other. Installation entrances of the electrical panel are isolated from the outside by adapters. A gasket is used on the cover for preventing dust entry into the electric panel. Measures have been taken against overloading. MEASURES Equipment is used where the operator could easily reach to stop the machine in any adverse situation during the rolling operation. These are the emergency stop buttons on the control panel. In addition, electrical and hydraulic measures have been taken against overloading. MAINTENANCE Thanks to the long-life parts used in our machine that do not require lubrication, maintenance time and cost have been reduced to a minimum, so premature wear has been avoided. PACKAGE The rolls, dies and processed surfaces are lubricated with special lubricant against corrosion. Attachments and additional dies are placed in either wooden or metal box or on palette as stretch wrapped based on tonnage and size. Based on size and tonnage, the machines are stretch wrapped and wooden pallets are attached to the base of the machines (foot parts), and nails are driven to these pallets to secure them on the truck, or the machines which shall to be loaded in a flat rack container or lowbed truck are fixed by steel rope and ratchet strap and welded on the carriers’ base from the underneath supports to prevent any slippage and also covered by nylon canvas. The machines are placed in a wooden box in accordance with ISPN 15 norms, when deemed necessary and with certain dimensions, for damage that may occur during transport.
