MG mh hydraulic 4 roll plate bending machine

MG MH Hydráulic 4 roll plate bendíng machines
TECHNICAL SPECIFICATIONS
» Frames made out of welded steel and worked on CNC-milling machines
» Rolls made out of forged steel C45
» All movements are hydraulic powered - this means no maintenance needed at all
» Power transmission of top and lower roll dírect on rolls with planetary gear box without secondary transmission
» Movement of side rolls on swing guídes to produce minimum díameters of 1,1-times to
roll diameter
» Pinching of material in both sides - prebending
» Levelling of side ro11s by torsion bars
» Conical bending system with conical movement of side ro11s and hardened cone attach block or hardened wheel
» Hardened rolls on 53-55 HRC Rockwell
» Control panel with digital read out for side roll position
» Hydraulic yoke to unload closed tubes
» CE safety device with security rope around the frame
» CE marc and letter of conformity

​​SW1NG BEAM SIDE ROLLS MOVEMENT
» The side rolls movement ís gııided by swing beams
» better power setting
» Less leg of power
» More bending quality

BENDING SVSTEM 3-ROLLS
» The material is pinched between the top Toll and the left side roll
» The first prebending is done by the right side roll
» Bending cycle with rotation powered by all 3 rolls until final position
» second prebending with the right síde roll
» The same working cycle can be done the other way round

SMALLEST DIAMETER:
On a capacity of 65 % of prebending 1, 1-times top roll diameter can be reached

SWING BEAM SIDE ROLLS MOVEMENT
» The side rolls movement is guided by swing beams
» better power setting
» Less leg of power
» Moгe bending quality

4 roll bendíng system
BENDING SVSTEM 4-ROLLS
» Use opposite side roll to square the material by feeding into the machine
u The materíal is permanent pinched between the top roll and the lower roll,no loose of control possible
» To reach the right cambering the pressíng power of the lower roll can be adjusted
» The first prebending is done by the right side roll
» Overtaking the bending process to the left side roll
» Bending cycle with rotation powered by top and lower roll until final positíon
» Second prebending with the left side roll
» The same working cycle can be done the other way round
