1.All parts of sheet bending machine use CAD/CAE/CAM software to
design so as to ensure the strength and rigidity of
2. our cnc bending machine machine is hydraulic upper driven.
3. our bending machine is mainly comprised of machine frame,
working table, ram, and main oil cylinder. The perfect design and manufacturing technology can
ensure the manufacturing and using precision of machine. The technological procedures of
main parts are as follows
4. Steel plate to warehouse → physical and chemical inspection →
steel plate ball blasting (dustproof) processing → cutting through CNC flame cutting
machine → cutting and processing to each welding junction plate → compound
welding → air protection welding → vibration aging treatment → processing through heavy-duty floor
type boring and milling machine, heavy-duty gantry milling machine → fabrication.
5.our bending machine is the frame type structure, whose the
installing faying surfaces of oil cylinders, lead rails, working table are processed at one time
work holding through the technological procedures of heavy duty floor type boring and
milling machine so as to ensure the parallelism and perpendicularity for each installing
6. The lead rails of machine users the advanced self-lubrication
material which does not need the regular lubrication and care.
7. The moving and positioning of left, right oil cylinder are
controlled by CNC system (Y1, Y2), which is composed by the electrical hydraulic
proportional valves, optical scales, CNC system. Each axis can be programmed individually, and
can be worked under programming so as to get the higher moving and positioning
precision when pressing the work piece.
8. The cnc bending machine can work normally under the eccentric
loading state because of using the electrical-hydraulic proportional synchronization which
can enhance the anti-torque, anti-eccentric-loading capacity extremely. The deformation
of working table and ram is very little when pressing because of the higher designing
rigidity of working table,
uprights, cross-beam and ram. So, the work piece can get the
perfect alignment and same pressing angle
9. The bending machine has the motorized back gauge, which is
driven by variable-frequency motor.
10. Tt has the front and rear supporting frame, on which has the
roller so as to feed conveniently.
11. steel bending machine has the side out-feeding mechanism so as
to effect the out-feeding conveniently.
12. CNC system is the suspended operating station which can swing
freely within the operating area, which also have the free movable foot/manual
13. Hydraulic System Y1, Y2 axes use the electrical-hydraulic proportional servo valve technique. Hydraulic system is made in Rexroth, Germany. The oil pump: internal gear pump, Rexroth.The dynamic seal rings for main oil cylinder is made in VALQUA,
Japan, which have the perfect sealing effect and long life,The oil level can be displayed clearly by the oil level meter set on oil tank, which has the oil filter mechanism and
blocking alarm function.Extra loading overflow protecting function on hydraulic
system.WC67Y Hydraulic Steel Sheet bending machine and Metal Plate Sheet Bending Machine
