STANDARD EQUIPMENT INCLUDED
STANDARD EQUIPMENT INCLUDED
The S-bend included in the hydraulic press brake design enables complex pieces to be produced, facilitating bending at both ends of the machine.
The LED directional light strip for lighting the bending zone permits the operator to work in optimum visibility conditions.
PUNCH PARALLEL ALIGNMENT
High precision can be obtained with the mechanical punch parallel alignment adjustment system.
The front arms which slide by means of recirculating ball screw guides enable the sheet metal to be held in position securely and can be fully adjusted both horizontally and vertically by hand.
The side doors of the hydraulic press brake have an electronic safety control device to manage their position and give information to user at all times via onscreen messages, and offer a large opening angle which makes it easier to change punches and dies whenever necessary. In addition, their design combines steel plate with a methacrylate viewing window so precision bending operations can be inspected in complete safety.
For maximum bending precision a GIVI MISURE high resolution (0.00020” / 0.005mm) optical encoder is used, which controls the vertical position of the bending axis (Y axis) for excellent reliability in each operation. Combined with control of lowering speed, this ensures punch holder plate vertical axis precision for bending operations and gives positioning error of less than 0.00040” (0.01mm).
The back gauge is fitted with ESA servo motors and precision BOSCH REXROTH recirculating ball screw guides which permit automatic positioning of X and R axes with 0.05 mm precision. It also has a manual adjustment system for the Z axis which enables the gauge callipers to be slid easily along a guide with recirculating ball screw system. The parallel alignment of the gauge callipers with the press brake punch holder plate is adjusted manually using micrometers to ensure maximum precision. In addition there is a mechanical offset system for Z axis curvature so that deviations can be corrected. • High speed measurement search: 565 mm/seg • Servo motor 1 Nm to 5000 rpm. • Back gauge displacement 600 mm.
Centralizing all the hydraulic components in a single unit improves their maintenance and management, giving a self-monitoring, redundant hydraulic system which provides working pressure information at all times by means of a manometer, and optics indication of the status of valves and sensors. In addition to the mechanical pressure limiter, electromagnetic safety valve and electromagnetic control valves for raising and lowering the punch holder plate,the hydraulic unit is fitted with two proportional servo valves, one for dynamic pressure regulation (servo valve E1) according to the requirements of each bending operation, and another for regulating the speed of the vertical bending axis (servo valve D1) to ensure highest working precision at all times. The electromagnetic valves are controlled at 24 VDC and have an LED light indicating activation status and an inductive position sensor with LED light for safety control.
The laser sensor system built in to the press brake has a metric guide to facilitate vertical adjustment and can easily be lifted up and removed when work tools (punches and dies) need changing. The system includes two electronically controlled high frequency laser emitters and receivers which are able to recognize and ignore any external light source and are thus protected from interference by any other lighting, whether natural or artificial. In addition, for complex bending operations on sheet metal with protruding areas which prevent the piece from being produced in the normal way, the laser sensor can be disabled by means of a push-button on the front of the machine which causes the press brake to operate at low speed. Moreover, the inclusion of electronic muting enables the laser sensor sweep extremities to be replaced with a novel parameterised system, where CNC control software controls the activation position of muting automatically at all times in relation to punch size and sheet metal thickness.
THE NARGESA CNC CONTROL
The powerful ESA S630 CNC control system has outstanding processing capacity which permits up to four axes to be managed, interpolated in any combination Y, X, R and Z, providing solutions for the most complex bending operations, and a flash memory for 5000 programs and a full library of Promecam punches and dies. CNC control is the core which runs all the systems and which now includes, amongst other innovative solutions, the adaptive electronic pressure control which calculates the force required for each operation and thus lengthens the life cycle of punches and dies; the electronic chassis bending compensator which plays a part in optimising bending precision with different lengths of sheet metal; and the efficient electronic system for hydraulic oil temperature compensation, permitting repeat bending operations to be performed at different working temperatures. The 10” high-resolution (1024 x 600 pixels) colour graphics touchscreen responds efficiently to user operations and provides clear and detailed information at all times. It enables programs to be edited graphically or numerically, new dies and punches to be managed, edited and added to existing libraries, bending sequences to be controlled, bending collisions to be controlled, bending simulations to be done, sheet metalwork to be calculated and machine sensors and inputs/outputs to be diagnosed in an intuitive and straightforward manner. Moreover it offers 20+ display language options, so the requirements of the majority of users are covered. In terms of connectivity, the CNC ESA S630 control turns the new Nargesa CNC hydraulic press brakes into just another item of equipment in the company LAN thanks to the Ethernet 10/100 Mbit port which enables remote control, management, software updates and diagnosis to be performed. In addition, USB 2.0 ports and a VGA connector allow CNC software to be updated locally and external peripherals to be connected, such as backup units, QWERTY keyboards, mouse or external display screen.
Sheet Metalwork and Bending Sequence Calculations
The complex algorithms processed by the CNC control enable the total worked length of the sheet metal to be obtained accurately according to the bending program. Furthermore, bending sequence management makes it possible to select the most suitable option for producing each piece, ensuring greatest ease for user who also has invaluable help in the form of the efficient 2-D visual bending simulator, which displays the positioning of the sheet metal in the press brake during each stage of the process, in addition to graphics display of the progress of different bending operations being performed. Naturally, the CNC control also takes care of running collisions calculation at all times, thus providing precise indication of any potential collision problem between the sheet metal to be bent, the punch and dies used, and the structure of the CNC ESA S620 control software can also be installed on any computer running the current version of the Windows operating system and has the same interface as the machine, thus minimizing the time required to become familiar with how it works and permitting two-way export of programs and tools between PC and machine.
Fitted with high-specification CNC control, the operation of these complex machines is now easier and more intuitive than ever before. It's color, high-resolution touchscreen graphics interface and powerful CPU enable the most complicated bending operations to be processed effortlessly and sophisticated algorithms to be calculated in mere microseconds, so you get the highest performance out of these pieces of engineering excellence.
