Yawei PBH CNC Press Brake machine

Standard configuration

• CNC controller is DELEM  DA53T, the Netherlands, 2D graph programming and display
• Hydraulic system is from HAWE, Germany, a full loop electric-hydraulic proportional servo control; ( Complete set means that pressure valves block, synchronizing valves block, prefill valves block are all imported); oil pump is VOITH/ECKERLE(110T), Germany and main motor is WN brand.
• Worktable is equipped with automatic CNC controller controlled hydraulic crowning system
• Backgauge for 80-250 tonnes is equipped with B type backgauge. Standard backgauge has two CNC axis (X, R) which can move integrally up and down . For X axis, the stroke is 500mm, the speed is 400mm/s, For R axis: stroke is 200mm, speed is 60mm/s; which is driven by AC servo motor, moved with ball screw-shaft, guided by linear guide; equipped with three finger-stops which can manually move leftward and rightward along the linear guide
• Supplying one set of European type mechanical fast clamp for machine 80-250T, die installation is 2-V+T slot quick change type (including one set of  domestic standard tooling). Supplying one set of European type mechanical fast clamp for machine 80-250T, die installation is 2-V+T slot quick change type (including one set of  domestic standard tooling)
• Supplying two fixed  front sheet support (can be moved leftward and rightward by the screws with standard distance)
• Supplying two sides door-type safety guard and rear safety guard with rear door; equipped with inside and outside main oil cylinder covers and covers for front and back crowning oil cylinder (safety guard and oil cylinder covers of 300T pressbrake are options)
• Machine paint is polyurethane paint, principle color: light grey with orange peel painting and covers are blue
• Supplying often-use internal hexagonal key spanner for adjusting tools

Main Specification

Equipment model：PBH-220/3100

Frame structure

• Structural feature of machine(it is new designed model after joint venture with SMS,Switzerland) Adopt the steel structure, wipe off the internal force through backfired after welding by quenching
• totally European new design, streamlined looking
• Complete steel plate welded structure, good anti-vibration
• Remove rust with sand-blast and coated with anti-rust paint
• Machine body is machined with once clamping for all machining surface from Spain five faces machining center, which assure parallelism and verticality between/among surface of the machine body.
• fornt support move manually by step
• Finish of Nippon Polyurethane paint

Ram structure

• Upper stroke design for bending, low noise, stable operating situation
• Double guide-way make ram to move more stable
• 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
• Able to move the ram up slowly, which allow the operator to control work piece conveniently
• Able to move the ram up slowly, which allow the operator to control work piece conveniently

Hydraulic system

• Close loop electro-hydraulic synchronized servo-control system, the most advanced
• Hydraulic system is from Rexroth, Germany
• Imported Heidenhain 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
• 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.
• Pipe fitting and seals of hydraulic system is imported from foreign country, good quality and high performance
• Overload overflow protection is outfitted to hydraulic system, which can assure no leakage
• Oil level can be read or seen directly

Back gauge position system

• Good for work piece needing multiple steps of bending with high precision requirement
• the speed of backgauge is fastest,and the precision is best in the domestic market
• X axis of back gauge is moved with ball screw, guided by linear guide, and driven by digital AC servo-motor. Back gauge is driven by digital AC servo motor
• Back gauge beam is box structure，with good enough mechanical strength and rigidity

Electrical system

• Electrical components are imported or from Sino-foreign joint Venture, in accordance with international standards, reliable safety, long life, good anti-interference ability
• Movable foot panel, with emergency stop button
• Special design about the worktable to decrease the deform of worktable
