FORMING AND BENDING EQUIPMENT: PRESS BRAKES

AUTOMATIC BEND SEQUENCES SIMPLIFY OPERATIONS
Bystronic Inc. (Hauppauge, NY) presents a new version of their popular mid-range press brake, the EP series. The EP series press brake, equipped with the Cybelec DNC 880S 2D control, is capable of automatically selecting bend sequences to simplify operations. The EP also features standard active hydraulic crowning which is capable of delivering exact bend angles across the entire length of the bed, reducing operator setup times and bend angle adjustments.

Bystronic Inc. has offered customers single source service expertise for over 30 years. They provide innovative laser cutting, waterjet cutting and press brake systems, system software and comprehensive customer training and support. The company?s North American headquarters is located in Hauppauge. Offices are also located in Chicago, Toronto, Canada and Guadalajara, Mexico. www.bystronicusa.com, sales.us@bystronic.om

HIGH-END FEATURES, AFFORDABLE PRICE
Cincinnati Incorporated's (Cincinnati, OH) Proform press brakes have been enhanced with features traditionally found on higher-priced, high-performance machines. Upgrades include:
? A bolt-on "quick clamp" ram nose as standard equipment.
? An optional bolt-on power clamp system designed to accommodate major manufacturers' die designs.
? An innovative, optional 5-axis backgage replaces the previous 4-axis backgage option.
? Enhanced software capabilities.

The Proform's powerful, PC-based control combines 3D graphics interface with simple touch-screen operation to speed setup and programming times, as well as optimize throughput. Precision servo hydraulics on a proven, rigid press brake platform allow the Proform to hold ram repeatability to ±0.001 in (0.025 mm) along its entire length. The Proform is available in 60 ton to 350 ton versions, in overall bed lengths from 6 ft to 14 ft.

The bolt-on "quick clamp" and optional bolt-on power clamp dramatically reduce setup time, while the optional 5-axis backgage ? with fast positioning speeds, flip backgage fingers with hardened dowel pins, 40 in gage points and auto flange correction ? provides the capability to handle a wide variety of complex parts.

The Proform's 15.1 in LCD touch-screen control uses simple icon-driven Windows® operating system, eliminating the need for keypads and key switches. Advanced control software allows helpful 3D rotational viewing of the part, detailing part shape and gage fingers. New part programs can be generated through manual data entry or by drawing the part in cross-section or flat pattern, and then selecting tooling and bend sequence. A special job setup page displays tool segment lengths and tool locations, as well as notes to reduce setup time.

Absolute linear transducers mounted on both ends of the machine provide automatic leveling control by maintaining parallelism between the bed and ram. The transducers are referenced below the neutral axis of the throat to avoid ram reversal errors due to side housing deflection. Each Proform press brake is tested before shipping to ensure ram repeatability to ±0.001 in (±3 Sigma).

Cincinnati has also integrated a number of its proven press brake design principles in the Proform to ensure reliable, long-lived operation. These include:
? Clevis-mounted cylinders and centerline loading that confine operating stress within the main housing to eliminate cylinder misalignment.
? Variable Volume Load Sensing (VVLS) hydraulic system for lower maintenance costs and greater energy efficiency.
? Hardened piston rods with precision guiding to eliminate cylinder oil leaks.
? Rigid interlock construction for maximum durability.
? Precision-engineered Microcrown machined into the press beds of 90 ton to 350 ton versions to reduce die shimming.

All Cincinnati press brakes are U.S.-made, manufactured in Cincinnati and customized machine orders are turned around quickly with Cincinnati's new demand-based, JIT manufacturing system. The company backs its Proform with five-year parts and one-year labor warranties. www.e-ci.com, info@e-ci.com

IDEAL FOR LESS CHALLENGING FORMING APPLICATIONS
LVD Strippit (Akron, NY) offers a line of PPEC press brakes designed as a mid-range bending solution to offer a balanced mix of performance and value for less challenging forming applications. PPEC press brakes, including PPEC-6 and PPEC-7 models, provide capacities from 80 tons, 2 m up to 220 tons, 4.2 m with four to seven CNC controlled axes, depending upon machine model.

PPEC press brakes provide a rugged, welded one-piece frame machined without repositioning guaranteeing machine precision. Hydraulic cylinders are machined from a solid steel billet. Pistons are steel forgings, precision ground and micropolished for years of trouble-free service.
Microprocessor Technology is linked to servo-controlled state-of-the-art hydraulics and electronics to ensure perfect control of the bending process and optimum precision. Double bed referenced encoders are connected to the bed in such a way that deformation of the side frames during bending does not influence the positioning accuracy of 0,01 mm of the upper beam (Y1-Y2).

The PPEC?s two-axis backgauge allows depth (X-axis) and height (R-axis) positioning of the two standard backgauge fingers. PPEC-6 and PPEC-7 models offer the additional flexibility of Z1 and Z2 motorized backgauge movement. The standard PPEC backgauge fingers allow gauging to 39.4 in (1000 mm) and also serve as material supports. PPEC-4 and PPEC-5 models can be fitted with an additional third finger support, which is ideally suited to the bending of channels.
A V-axis crowning system fitted to PPEC-5 and PPEC-7 models ensures parallel and consistent bending results on longer bending length over the different tonnage levels.

All new PPEC press brakes are equipped with LVD Strippit?s CADMAN® Lite control. Based on the same easy-to-use platform as the full-featured CADMAN® Touch control, CADMAN Lite offers a number of the same key features, including 2D graphic programming with automatic collision detection, direct angle or Quick Bend programming, and connection with LVD Strippit?s CADMAN-B offline programming software. The LVD Group is a leading manufacturer of a comprehensive range of sheet metal/plate working machine tools and software solutions, including laser cutting systems, punch presses, press brakes, guillotine shears and mid-level automation systems, integrated and supported by its CADMAN® PC-based Windows® compatible software. www.lvdgroup.com

HIGH SPEED RAM
Bystronic introduces a new high speed ram option for the standard range Xpert series press brake. The new high speed ram positioning system is capable of reducing bend cycle times by 15 percent to 35 percent, in reaching approach speeds of up to 600 ipm and bending speeds up to 47 imp without sacrificing accuracy. It is the only press brake that introduces no angle errors itself with a ram positioning accuracy of .00015 in. Xpert technology dynamically adjusts ram position and crowning in response to material properties, achieving unmatched accuracy. The Xpert series covers 60 tons to 4000 tons and bed lengths from 6 ft to 60 ft in length. The Xpert series is available in Standard, Large, Mammut, Tandem, and Robot configurations.www.bystronicusa.com, sales.us@bystronic.om

CNC PROGRAMMABLE SHEET SUPPORT SYSTEMS INCREASE PRESS BRAKE PRODUCTIVITY
LVD Strippit offers T-axis CNC programmable sheet supports for its PPEB and Easy-Form® series of precision hydraulic press brakes. The use of T-axis programmable CNC sheet supports facilitates one-person operation and enhanced angle repeatability, part quality and ease of material handling, improving overall press brake productivity. Unlike traditional pneumatic type sheet supports that typically do not support the part during the entire bending process, LVD Strippit?s T-axis system features synchronous brushless motors to follow and support the sheet before, during and after bending.

LVD Strippit?s T-axis sheet supports are fully synchronized with the bending speed of the press brake, providing smooth operation and facilitating an accurate, consistent bending process. T-Axis trajectories are calculated automatically by the press brake control depending upon the size of the V-die. The sheet is completely supported during bending by the synchronized action of the rotation movement and the vertical movement of the CNC support units. Two types of T-axis sheet support system are available: a unit for machines from 80 tons to 220 tons able to support up to a 100 kg/221 lb sheet, and a heavy-duty system suitable for press brakes 320 tons and higher able to support up to 200 kg/441 lb.www.lvdgroup.com
