380V/60Hz/3 Phase

Note:Y1,Y2 axis- controlling the movement of arm

X axis- controlling the movements forward and backward to back gauge

V axis-automatically hydraulic crowning compensation to the worktable

2) Structural feature of machine:

Totally European design,streamlined looking

Taking off inner-stress of welded parts by tempering,good stability

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

Supplying three front sheet supports

Finish of Nippon Polyurethane paint

3) 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

whole structure of the hydraulic press brake:

1.Totally European design, streamlined looking,Monoblock,Welded steel frame rigid to deflection moment and high tensile with ST44 A1 material.

2.AccruL PRESS BRAKE incorporates ESTUN E210 NC controls offer not only failsafe operation of the vital operations of the machine,but also offer the operator considerable assistance in carrying out the entire bending process.

3.High accuracy,high efficiency,simple and convenient operation,good performance, favorable price and best service.

1. Hydraulic system:

1. Adopt integrated hydraulic control system, more reliable and easy for maintenance.Hydraulic system is from Bosch – Rexroth,Germany.

2.Extremely reliable and precise Bosch – Rexroth valves are used for the regulating circuit. Every complete working cycle can be achieved through the control of hydraulic valve.

3.Overload overflow protection is outfitted to hydraulic system,which can assure no leakage,and the oil level can be read or seen directly. Being able to work under rated load continuously,stable working and high precision.

4All seals in cylinder is PARKER from USA,the most famous brand,good quality and high performance

2. Electrical system and the safety interlock:

1.Electrical panel with cooling system designed to meet CE Standards and composed of automation and electrical equipments with SIEMENS brand.

2.Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.

3.Front Side Covers with safety switches, Back light safety guards (Category-4),Foot pedal conforming to CE regulation.

4. The machine by the European Union CE certification and ISO quality system certification

3. Synchro control system:

1. Slide synchro system:adopt steel torsion bar synchro system, simple in structure and high in accuracy,ensures the parallelism between beams is used for the synchronism

2. ends of slide has 2 synchro fork which make,The system uses upper die compensation to improve the brake precision.

3.The worktable adopts the particular design,reducing the crowning distortion amount of lower tool effectively.

4. Ram Structure and Bending precision:
