OPERATION PROCESS
Material you want to bend is placed between the rolls on the center so that it shall be as
near as possible to the own axes of the rolls. Try to achieve the best alignment at this time.
All following operations is the same as the normal bending procedure. You shall clean and
prepare the plate before the start of the operation as conical bending is a difficult procedure
and machine works under a specific pressure.
Side supports of the machine slightly opens as the cones are pushed during conical bending.
If this happens, check the dimensions of the cone again and ensure machine may perform
this operation.
POINTS TO BE CONSIDERED DURING CONICAL BENDING AND PLACEMENT OF CONE
MATERIAL
The small diameter of the material shall be leaned on the cone support roll. Bring the side of
the angled cone plate that you will start to bend in parallel with the axes of lower and upper
shafts. Cone is compressed by pressing the lower roll up button after bringing the lower roll
cone button on the control panel to the cone position when 5 to 8 mm is left to the
compression of the plate after raising the lower roll. Compression shall be visually inspected
in this operation. Plate shall be rotated from the bigger diameter side of the plate that shall
be bent conically for bending operation. Side shaft is slightly raised in parallel position. Then,
side shaft cone button is brought to cone position. Bending operation is started when the
desired cone angle is achieved by pressing the lifting button.
When the shaft comes over the other side shaft, the other side shaft also brought to conical
form in the same way. When the ends of the plate come together in conical bending
operation, plate is spot welded from the inside and outside. After the machining of weld
surfaces, calibration is performed. Lower cone is closed when this operation is completed.
Lower roll is lowered. Cover is opened using the cover opening/closing button. Upper shaft is
raised and operation is completed.
If these operations are not followed:
• You compress it further instead of adequately compressing with the lower shaft from
the bigger cone side of the plate.
• You may inadvertently compress the cone plate as parallel instead of the cone.
