The whole structure of Press Brake: -Totally European design, streamlined looking, Monoblock, Welded steel frame rigid to deflection moment and high tensile with ST44 A1 material. -PRESS BRAKE is Equipped with the Estun user-friendly interface, the E21 provides all main press brake functionality. -Automatic tonnage and stroke adjustment for bending angles. Perfect bending results with easy angle input and operation of machine. 1. Hydraulic system -Adopt integrated hydraulic control system, more reliable and easy for maintenance. Hydraulic system is from Rexroth, Germany. -All pipes, flange and joint with vibrations proof and leakage proof design and setting. -All seals in cylinder is DZ from Taiwan, the most famous brand, good quality and high performance. -Overload overflow protection is outfitted to hydraulic system, which can assure no leakage, and the oil level can be read or seen directly. -The hydraulic system is made in compliance with current regulations. 2. Electrical system -Electrical Cabinet under the standard of IP55, Electrical under international CE Standard, safe and reliable, strong anti interference capability. -Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate. -Front Side and back safety guards, Foot pedal conforming to CE regulation. 3. Synchro control system -Patented hydro-mechanical system for exact parallelism and a high repeat accuracy. -The worktable adopts the particular design, reducing the crowning distortion amount of lower tool effectively. -Adopt steel torsion bar synchro system, simple in structure and high in accuracy, ensures the parallelism between beams is used for the synchronism. 4. Mould and dies -The equipped standard Dies, special non-standard mold is available under client's requirement according to real workpiece situation. -Upper and buttom die can be sectioned according to customer’s requirement. 5. Backgauge -Back gauge fingers with two gauging steps used one for short and the other for long bending depths. -Back Gauge positioning fingers move along linear bearings with ±0.05 mm. positioning tolerance. 6. E21 NC Controller -Backgauge and block control -Control for AC motors, frequency inverter -Intelligent positioning -Stock counter -Holding/decompression time setting -Program memory of up to 40 programs, up to 25 steps per program -One side positioning -Retract function -One key backup/restore of parameters -mm/inch -Chinese/English
