SKZX□□□×□□□Full servo CNC Spreading Machines are the third generation of coil spreading machines newly developed by our company. They are with higher precision, faster speed, better coil forming and more convenience comparing to our second generation spreading machines. A number of independently-developed proprietary technologies of our company have been used. Control of parameters such as the coil length, end height, coil span and angle are controlled accurately by servo motor. This machine has been granted a Certificate of Utility Model Patent by the State Intellectual Property Office. Blanks in the types represent the shuttle length and the coil span.
The machine mainly consists of stationary body, moving body, guide rail, hydraulic station, digital control & detection system and 4 spreading arms.
To start operation, place the coil onto the machine, press START, the coil will be straightened and centered quickly. Next, the manipulators on 4 spreading arms grasp respectively the straight edge part of the coil; during spreading, 4 spreading arms go outwards and the end nose go up and inwards, the manipulators rotate and finish the movement to form the coil to the right span, length, end height and angle.
After the forming movement, the add-on lower arc push up unit moves upwards and inwards to form coil arc.
Upon completion of coil spreading, the manipulators get released, unload the coil,reset the machine and proceed with the next coil.
