650 Ton Synchro Semi Automatic Mast pole CNC Tandem Press Brake Manufacturer
electric tandem Press Brake Machine,automatic press brake
Features of press brake forming:
1. Overall welded and processed structure.
2. Closed loop control mode composed of electric-hydraulic servo valve and measure ruler.
3. Ensure the highest control precision, bending accuracy and repositioning accuracy are
also reach to the highest level.
4. Back gauge mechanism can be multi-axes controlled.
5. Integrated hydraulic system decrease the pipe connections, oil leakage, and increase the
stability and overall beautifies.
6. Worktable equipped with hydraulic and mechanical compensation to avoid the deformed
upper beam from affecting the quality of the work piece, it is adjusted automatically by the
CNC controller with convenient and accuracy.
7. CNC controller normally uses Holland DELEM, Italy ESA, Swiss CYBELEC, all with
Description of press brake bending machine:
1. The frame of mini press brake machine is composed of tank, worktable, left and right housings
and RAM. So it has high strength and good rigidity. Also it takes vibration to eliminate
2. Synchronization working principal of both machines: Adopting electric-hydraulic
Proportional valve to ensure the synchronization of both machines. The proportional
valve is made by BOSCH company with very good performance such as small friction
between mechanic action pairs, fine electronic amplifier and electric magnet with high
controlling force and continuous action. There are two raster displayers on both sides
of machine to inspect the position of RAM continuously and feed back the signal to
control system, then the control system will control electric-hydraulic valve to make
two cylinders synchronization on one machine. Because the raster displayers are
installed to "C" plates, not on housing
plates directly, the deflection of RAM and frame when working will not effect its measuring
and controlling precision. When two machines working together, the differential potentio
meter installed between two machines will transfer the mechanic synchronizing signal
into electronic one and feed back to synchronization plate and control system.
The signal will be enlarged by BOSCH amplifier to control the synchronization of
both machines by controlling electric-hydraulic proportional valve. So the
synchronization of two machines is achieved with high precision.
3. Through computer, the operator could communicate with machine. The computer has
several service language, calculate and adjust the bending force automatically. Also it could
calculate and control the dead point, speed changing point. The strokes (Y1, Y2) of RAM
could make a small tilt to meet the special requirement of user.
4. Equipped with good guiding system, position measuring system and hydraulic balance
systemto meet the requirements of full length job and eccentric job.
5. Worktable compensation unit is adopted to make up for deflection of machine when
working to make sure the precision of work piece.
6. The surface of cylinder has good wearing and heat treatment, so it has good lubrication
and long service life.
