5 8 9 Va r i o P r e s s At the right angle safely. A new safety solution and a highly accurate angle measurement system effortlessly ensure the success of every bending task. Maximum precision from the very first bended part is a matter of course with the VarioPress. The highly sensitive Operator Safety Guard productive (OSG pro) safety technology, the tool-independent Laser Controlled Bending (LCB) angle measurement system, and the dynamic hydraulic drive assist you in every bending task and help optimize your internal production processes. EVERYTHING UNDER CONTROL. Safety has always been a major concern for EHT together with Pilz GmbH & Co. KG we have now developed a new camera-based safety solution, the OSG pro (Operator Safety Guard productive), that makes press brakes, and particularly the VarioPress, even quicker and safer. The dynamic muting function of this safety system shortens the bending cycle time considerably because the upper tool can travel almost to the workpiece at maximum speed whilst maintaining enhanced safety. AT THE OPTIMUM ANGLE. The EHT LCB (Laser Controlled Bending) angle measurement system optimizes your bending results from the very first bended part because it prevents a complicated adjustment process and reduces the number of rejects to a minimum. The latest developments in laser and optical electronics form the basis for a highly precise and powerful device that offers flexible use. As a result of its design as a tool-independent unit, the LCB can be used with many tool geometries and special tools, and offers the right response to rising cost pressure and increasing quality demands. OSG AND LCB YOUR ADVANTAGES: 1. Shorter bending cycle time and increased safety thanks to dynamic muting 2. Maximum angle measurement accuracy for high-quality parts from the very first bend Flexibility made easy: The angle measurement system can be freely positioned over the entire work length, either manually or as an optional NC axis. Dynamic muting: While with normal muting processes the upper tool can only travel the final millimeters to the sheet at the permitted speed of 10 mm/s, with dynamic muting it travels at maximum speed until it almost touches the workpiece. The path that the upper tool travels with reduced speed is thus decreased to a minimum.

6 10 11 Va r i o P r e s s Intelligent and flexible. The clever VarioPress tool concept and the precise crowning system ensure easy handling and optimum bending results. The intelligent tool concept of the VarioPress stands for maximum flexibility and economic efficiency. By combining the fully automatic CNC with the point-based crowning system you can balance tool accuracy and tool wear. You thus have the press brake totally under control. INTELLIGENT TOOLS. The VarioPress lives up to its name regarding its tool system: differing bottom tool clamping variants one mechanical (basic configuration), one pneumatic and one hydraulic design permit tool technology that is precisely coordinated to your range of part production. Moreover the bottom tool shift of the VarioPress combined with the Multi-V tool offer a major advance in efficiency: Two different bending operations can be carried out with just one tool. Even the most complicated geometries can be implemented in one pass. And it is child s play to integrate even special tools, thanks to the CNC-controlled incremental bottom tool shift. MULTI-V YOUR ADVANTAGES: 1. Low tool costs 2. Short equipping times through combination with bottom tool shift 3. Less storage space required PINPOINT PRECISION. The VarioPress crowning system offers the possibility of achieving pinpoint calibration independent of the fully automatic CNC crowning system of even the most varied of forming zones, e.g. blowouts in the bending zone. In this way, accurate and consistent bending angles can be achieved effortlessly. In addition, the crowning curve can be individually adapted for centralized or off-center bending. Pneumatic design: System for accepting Multi-V dies with pneumatic tool clamp. Single-V dies (13 mm acceptance size) can be used with supplementary adapter bar. Mechanical design: System for accepting block dies with mechanical tool clamp. Single-V dies (13 mm acceptance size) can be used without supplementary adapter bar Selective crowning system: The crowning curve can be individually adjusted every 250 mm. Bottom tool shift: Folding or pre-bending without tool change is possible with the VarioPress thanks to bottom tool shift. Great bending freedom: The VarioPress offers you a free choice and maximum flexibility regarding the desired tool. Because, thanks to the bottom tool shift in combination with Multi-V tools it is possible, for example, to achieve pre-bending and folding without changing the tool.

7 12 13 Va r i o P r e s s Perfectly positioned. The correct stop system and optimum material handling completes the VarioPress. Totally in line with customer requirements: regardless of whether 2, 4, 5 or 6 axes, whether a support bracket or bending aid you decide what your VarioPress looks like. We thus guarantee that your VarioPress is precisely configured to your needs and bending demands. A PERFECT FIT. The VarioPress offers differing back gauge systems depending on part geometry and complexity. They are both particularly precise thanks to a special rack and pinion drive and high axis dynamism. You can choose from between three different systems for your VarioPress: System I (the standard system) is available with 2, 4 or 5 axes and can be positioned in the X-, R- and Z-directions. The same applies for system II which, however, is ideally suited for the use of back bending aids and sheet supporting systems. With system III (6-axis system) every stop finger can be independently moved to any desired position offering maximum freedom for flexible production, for example with bending lines running diagonally to the stop edge. GRASPING THE CHALLENGE. The VarioPress can be equipped with support brackets or supplementary bending aids depending on the application. Even handling-intensive, heavy or unstable bending parts can thus be worked on by a single operator. The bending aids can be moved laterally over the entire bending length and are adjustable according to the particular bottom tool height. The bending aid can withstand a load of up to 3000 N. YOUR EHT OPTIONS YOUR ADVANTAGES: 1. Maximum precision and dynamism with all stop systems up to 1200 mm/s (up to a bending length of 6050 mm) 2. Stop systems selectable according to requirement: 2, 4, 5 or 6 axes 3. Optional bending aids save time and energy 4. Supplementary support brackets for light and thin metal sheets Maximum freedom if required by customer: The 6-axis stop system for particularly flexible production. Optimize your VarioPress: All EHT stop systems and bending aids (optional) offer maximum precision and dynamism and thus permit perfect bending results from the very first part. Standard bar system for 2 to 5 axes. Bar system for 2 to 5 axes (especially for bending aids and sheet support systems at the back). Modular system for 6 axes. X-axis R-axis X1-axis Z1-/Z2-axes X-axis R-axis X1-axis Z1-/Z2-axes X1-/X2-axes R1-/R2-axes Z1-/Z2-axes

8 14 15 Va r i o P r e s s More than just options. You have ambitious plans? Manual tool changes take too long? Our tandem machines and EHT ToolShuttle are the solution. With our premium press brake we place the greatest value on flexibility and customerspecific configurations. Our tandem press thus allows you to produce an extraordinary range of part lengths and change tools particularly rapidly and safely with the ToolShuttle. QUICKER AND LESS COMPLICATED TOOL CHANGES. Tool changes on large press brakes do not just involve a lot of physical effort they are also very time-consuming. Companies that produce in small and medium-sized batches, in particular, thus waste valuable hours re-equipping several times a day. The EHT ToolShuttle shortens equipping times immensely and ensures considerably increased safety at work. The tools drive into your machine easily and rapidly on ball-bearing-mounted guide rails and ensure the immediate operational readiness of your VarioPress. A POWERFUL DUO. It is not the machine that should determine the part length but quite the reverse. For this reason, the usual maximum machine length of about 10 meters cannot be the last word. EHT offers you tandem press brakes that can be used and operated either individually or together for maximum bending freedom! TANDEM, TOOLSHUTTLE, FLOOR- MOUNTED YOUR ADVANTAGES: 1. Bending on up to 20 meters thanks to tandem design 2. Increased productivity through individual or tandem operation 3. Quicker and easier tool changes thanks to ToolShuttle 4. No expensive foundations thanks to floor-mounting STRONG EVEN WITHOUT FOUNDATIONS. Large heavy machines mostly have only one optimum position if they are anchored in a foundation. The VarioPress, however, is also available as a floor-mounted machine even with a bending length of up to 6 meters and a bending power of 400 tons. The advantages are obvious: freely selectable and changeable installation location, no costs for complicated foundations, and high price stability on the second-hand market. Heavy equipment: A tool change can be a major time and cost factor particularly with small batch sizes and heavy tools. The EHT ToolShuttle is your path to more efficient and safer production. A press power of up to kn and a bending length of 20 meters: The VarioPress as tandem machine is a customized, highly accurate, giant.
