Performance
◇ The frame is steel-welded construction,vibration to eliminate stress,with high strength and good rigidity.
◇ Forcing-torsion bar maintains synchronization for the two pistons ,with the higher parallelism to the table.
◇ Mechanical stop must ensure stable and reliable positioning accuracy.
◇ The ram is adopted hydraulic top-drive with two cylinders. Working pressure is stepless control and the time of retaining pressure can be easily adjusted by turning the knob,lower noise.
◇ The ram"s stroke and the back gauge"s position can be speedily adjusted by motor and fine adjusted by handwheel.
◇ The adjusted value is displayed on the numerator.
◇ Ram possesses three strokes i.e. inching, single ,continuity
◇ The main sliding pairs such as oil cylinders,piston rods, guide ways and etc.are all treated with wear-resisting measures.
◇ Heat-treated tooling is with the wearablilty. The satisfactory bending accuracy can be obtained through adjusting of deflection compensation unit of the slanting wedge installed on the top of the tooling.
◇ Crowned bottom die holder for deflection compensating is adopted for the machines above 4 rice.
◇ Full machine is guarded with safety interlocker that is set in the electric box by automatic cutting off main power when the box door is opened.protecting barrier with safety interlocker is mounted on the back of the machine. Another, there are travel limit and foot pedestal mounted emergency off switch.
Optional:
◇ Sectional tooling with different lengths may store forming a certain length to bend the closed frame workpiece.
◇ The adjusted value of the ram and the back gsuge can be displayed by digital readout (electronic displays).
◇ Pendant control box.
◇ Two-hand control device.
◇ Photo-electricity protection(infra-red light sensor to monitor load area).
◇ Any tailor-made are available on request.
