9.7. BENDING OPERATION LINE OF THE MATERIAL
Ş EK İ L 1 : Bring down the top rolls low and rear shaft according to the bending material
thicknees .
Ş EK İ L 2 : Ride the material which will bending between the top rolls shaft.
Ş EK İ L 3 : Put into place the sheet according the top rolls on the page 23 determine at the figure.
The top rolls shaft bring up and tight the material.
Ş EK İ L 4 : Pull the material near the side top rolls axis.
Ş EK İ L 5 : To make the prebending, bring up the rear top rolls shaft at the required diameters.
Ş EK İ L 6 : Press the foot pedal(turn the button)turn slowly the material.
Turn the arm at the type of the machine with arm.
According the requiring diameter, control the prebending operation with the preparing stencil.If
the prebending operation is right,turn the sheet metal backword side,and the same operation
repeat at the edge of the other side.
RE
Ş EK İ L 7 : To reaching the require diameter, rotate the rear shaft top rolls up.
Ş EK İ L 8 : Reaching to the requiring diameter, one or two time rotate the material and make the
calibre.
The important component for the right measured bending material, is the development sheet
metal.According the bending form the development of the sheet metal must correct accounting
and cutting.
At the bending operation the other important component for the material ,is between the lower
and upper rolls is the pressing strength.The pressing of the lower and upper rolls with the
standard machine is done with hand arm,and the requiring special equipments with motor.
If the lower pressing strenght is possible bigger,the sides of the bending material will touching
and the middle will be separated. For this kind of defect,it is say the barrel mistake.If the lower
strenght is possible small ,the sides of the bending material will separated,and the middle will be
touching.For this kind of defect,it is say the opposite barrel mistake.
Barrel Mistake Opposite Barel Mistake
