BENDING & CUTTING TECHNOLOGIES

BENDING PROCESS Most of the processes sheet metal forming involve initial folding of the blank. Different bending processes are widely used in a wide range of products: automotive, furniture, doors, trains, construction, aeronautics, electronics, telephony, ships, etc.. We can say with good reason that the process of folding a sheet find a place in the vast majority of the products. Despite its apparent simplicity, the bending process is a highly complex manufacturing technique that must be understood, led and dominated. A bend is the permanent deformation of sheet metal under the effect of...

BENDING FORCE AIR BENDING Among the V-bending processes, air bending is the simplest one and it is commonly used in a wide range of productions. The Air Bending process involves the punch pressing the sheet metal down into a V-shaped die. This way sheet metal flanges are folded up, creating the angle at the contact point between punch and sheet metal. The sheet metal has 3 contact points with tool and die. The bending angle is determined by how deep the tool pushes the sheet metal into the die. The spring-back is compensated by a longer stroke, allowing the plate to return to the required...

BENDING FORCE BENDING FORCE RULER The bending force ruler is an easy tool to define the required bending force per meter (t/m), given the thickness (s), The value given refers to air bending process, mild steel and a 90° angle. However, the tool includes the correction factor to be applied, depending on angle, material and bending process. Schiacciata completa - Complete flattening Schiacciata parziale - Partial flatten. Bending force V Aperture cava - Die opening B Bordolnt. mln. - Min, flange lenght r Ragglo Interno - in ternai radius Plate of mild steel, thickness = 1.2 mm The square in...

ECO CONCEPT e X-PRESS ECO In line with our strategy based on the continuous innovation, we are proud to introduce the Eco Concept: a package of innovative and customer oriented solutions aimed at reducing machines’ consumptions. On X-PRESS eco, thanks to a new configuration of the hydraulic pump, we monitor the flow rate in the hydraulic circuit depending on the bending process. The motor is controlled by an inverter and it is activated only when the machine has to operate, always delivering only the power requested by the bending process. The right pressure on the circuit is granted also...

ACTIVE CROWNING SYSTEM ACSG REFLEX PROPORTIONAL FRAME DEFLECTION COMPENSATION SYSTEM Maximum accuracy and absolute repeatability are the trademark of X-PRESS eco series thanks to the systems ACSG, reflex and GPS4. The X-PRESS eco is equipped with the active crowning system family ACSG, simply one of the best crowning system on the market. No matter how you act your crowning system (mechanically with wedges, hydraulically with pistons, etc.) the key is how you manage your crowning system. ACSG simply does the job: ACSG bends the lower beam following in real time the bending of the ram no...

ANGLE CONTROL SYSTEM GPS4 FRONT SUPPORTS The new X-PRESS eco can be equipped with the patented angle and control system GPS4, simply one of the best angle control system on the market. GPS4 constantly controls and adjusts the bend angle throughout the bending process via the CNC. GPS4 ensures angular accuracy regardless of material variations and forming conditions as it eliminates the influence of bend length, press force and off center loads. The result is maximum precision, absolute repeatability. No material setting, no sheet length setting, no bending force setting, no sampling test,...

FRONT SUPPORTS BACK GAUGES: THE RANGE X-PRESS presses can be equipped with a wide range of back gauges to meet the most varied production needs. The series RPS, RPL and RPG are characterized by robustness, accuracy and repeatability. FSA-C This type of front support has a pneumatic height adjustment (dual positioning), controlled by the CNC. This function is useful both when working with hemming bottom tools, which require positioning the plate at a different height as needed. All back gauges*, also in the basic 4 axes configuration, can be moved and repositioned without having to access...

BACK GAUGE: SERIE RPS BACK GAUGES: SERIE RPL-3 The back gauge RPS consists of a one-piece structure, driven by rack & pinion travelling on recirculation balls linear guides. It includes an X and R axes (depth and height) in the standard configuration and is fitted with two reference back fingers, mounted on linear guides. The guide profile is made of an aluminum extruded part which design grant a high rigidity and thus precision. All axes of the back gauge are programmed for maximum speed for all movements and for deceleration when nearing requested distances. The back gauge has an...

BACK GAUGE: SERIE RPG UPPER TOOLS The back gauge type RPG is extremely sturdy and precise, suitable to making heavy work and any type of bending. In order to assure this level of performance the back gauges are designed and manufactured with high technology, sophisticated and reliable components, providing a wide handling range, an easy oblique positioning, a very high precision and the possibility to integrate back sheet followers. 8 axes fully indipendent The back gauge type RPG consists of two trolleys, each equipped with 3 axes X-R-Z which are moved by guides, ball screws and AC motors....
