Attachment with the machine& Machine key components list

The Whole Structure of Press Brake

1. Totally European design, streamlined looking.
Taking off inner-stress of welded parts by tempering, good stability.
2. Remove rust with sand-blast and coated with anti-rust paint
Adopt Spanish pentahedron machine center, once clamping can finish all working surfaces which will guarantee dimension precision and position precision.
3. The design of the machine frame is a critical part of any machine with relation to its ability to produce accurate parts for a long period of time.
4. Frames, assembly surfaces and connection holes are machined after the welding process, up to 60′ in a single pass.
5. Supplying three front sheet supports , Finish of Nippon Polyurethane paint.

Ram structure

Upper stroke design for bending, low noise, stable operating situation , Parallel tolerance of Y1 and Y2 is 0.01mm
Y1,Y2 can be programmed separately can work under non-balance load, can bend cone-shape work piece
At bottom dead center a pressure-keeping time is offered, and can be programmed to assure precision of all kinds of work piece. Can move the ram up slowly, which allows the operator to control work piece conveniently Universal fixing-surface of the upper tool can be meeting with the clamping requirement of the tool farthest！

Hydraulic system

1. Close loop electro-hydraulic synchronized servo-control system, the most advanced Hydraulic system is from Rexroth, Germany, a full loop electric-hydraulic proportional servo control, Sumitomo oil pump, Japan.
2. Imported linear optical reader, guiding system, positioning system and hydraulic balancing system with high precision, which all can permit the processing work piece of full length or with eccentric.
3. An outfit with “C” is at throat, as deformation compensation on throat, directly measuring the distance between upper tool and low die, assuring the precision of work piece.
4. All seals in cylinder is imported, the most famous brand, good quality and high performance.
5. Overload overflow protection is outfitted to hydraulic system, which can assure no leakage, and the oil level can be read or seen directly.
6. Being able to work under rated load continuously, stable working and high precision.

CNC Back gauge

1. Close loop electro-hydraulic synchronized servo-control system,the most advanced Good for work piece needing multiple steps of bending with high precision requirement.
2. X is moved with ball screw,guided by linear guide,and driven by digital AC servo-motor.
3. Back gauge has well enough mechanical strength and rigidity with tank-type gauge structure.
4. Two fingers are moving alone swallow guide,operate easily with high precision
5. Particular finger-stop design,enlarge the range of back gauge.

Electrical system, SCHNEIDER Electrical

1.Electrical components are imported or from Sino-foreign joint Venture,in accordance with international standards,reliable safety,long life,good anti-interference ability,a radiation unit is fitted in electrical cabinet.
2. Having a movable single-hand pedal switch with emergency stop,easy to operate.

Crowning compensation, To avoid right conditions

1. Low worktable has an automatic crowning compensation uint; compensation amount is automatically set up by CNC system, with guarantee a same bending angel on full length.
2. The worktable adopts the particular design, reducing the crowning distortion amount of lower tool effectively.
