 Three roller coiling machine 
 Three Roller Bending mechanical and hydraulic: Mechanical three roller coiling machine is divided into symmetric and asymmetric mechanical three rollers symmetric rolling machine: mechanical three rollers symmetric rolling machine performance characteristics: the machine structure type three-roll symmetrical central symmetrical position in the two lower rollers on the roller moves vertically through the worm drive of the lead screw mother, two rollers rotates through the reducer output gear and roll gear meshing, provide torque to the roll sheet. The shortcomings of the aircraft requires the use of other equipment is the plate end of the pre-bent. 
 Mechanical three rollers symmetric rolling machine 
 Mechanical three rollers symmetric rolling machine main feature: the aircraft structure type for the non-symmetric three-roll, roll on the main drive roller moving vertically, so that the clamping plate, and under the roller gear roller gear meshing , at the same time as the main drive; side roller shall be poured down movement with the pre-bending and rolling of the dual function. Compact structure, easy operation and maintenance. Technical parameters: Model Coil thickness 
 Machine features: A. PLC control, machine operation is very stable. 
 B. arbitrary choice of manual, automatic, semi-circle, the whole cycle a variety of functions. 
 C. two kinds of angle setting (0 to 185 randomly selected) single selection can also be two kinds of continuous selection. 
 D. Mobile pedal switch, with automatic start, emergency stop, tight stop to continue the three functions, safe. 
 E. The high-capacity cooling system, make the machine run more stable. 
 F. mold replacement is simple and convenient, easy and flexible production. 
 G. nose, elbow sleek design to provide maximum elbow space.
