Cincinnati Incorporated has upgraded its Proform press brake with the introduction of the Proform+ model. The Proform+ adds dual pressure transducers on its hydraulic cylinders for increased tonnage accuracy, and digital encoders provide ±0.0004" (0.01 mm) ram repeatability for close tolerance forming and higher part quality.
The press brake's PC-based control is now bed-mounted to the machine with a swinging pendent arm mount, and has been upgraded to include a trackball and keyboard. An optional Wila crowning system compensates for bed and ram deflections during bending, and, according to the company, eliminates the costly trial-and-error approach used in traditional die shimming.
The Proform+ is also available with factory-installed LazerSafe guarding that provides users with another choice for safeguarding operators. Available Proform+ models include 90 to 350 ton capacity and overall bed lengths from 8' to 16'.
"Clevis-mounted cylinders and centerline loading confine operating stress to the main housing, eliminating cylinder misalignment," said a company spokesperson. "The Machine's Variable Volume Load Sensing (VVLS) hydraulic system is designed to lower maintenance costs and increase energy efficiency. Hydraulic cylinders use hardened piston rods with precision guiding to minimize oil leaks, and the machine's heavy plate frame is precision machined and rigidly interlocked - not welded - to better resist deflection."
The digital encoders mounted on both ends of the machine provide automatic leveling control by maintaining parallelism between the bed and ram. Automatic deflection compensation is designed to avoid ram reversal errors due to side housing deflection. Precision servo hydraulics on a rigid platform, along with the high-resolution encoders, allow the Proform+ to hold ±0.0004" ram repeatability along its entire length.
The Proform+'s PC-based control combines 3D graphics interface with touch-screen operation to speed set-up and programming times, as well as optimize throughput. 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 job set-up page displays tool segment lengths and tool locations, as well as notes to improve part consistency.
The 15.1" LCD touch-screen control uses an icon-driven Windows-based application compatible with other Cincinnati press brake models.
The Proform+ is available with a variety of tool holders, filler blocks and clamps to accommodate most major tooling types, including American or European-style tooling. The press brake includes standard bolt-on manual quick clamp or optional bolt-on hydraulic clamps to accommodate major manufacturers' die designs. Both clamps are designed to reduce set-up time. An optional 5-axis backgage features fast positioning speeds, flip backgage fingers with hardened dowel pins, 40" gage points and auto flange correction to handle a variety of complex parts. In addition to the Wila crowning system, the Proform+ is also available with Cincinnati's Auto Crown, an automatic, hydraulically-powered crowning device that can produce angles within ±1/2° variation along the bend line.
All Proform+ models have a quick-access emergency-stop button in the center of the operator station, with an additional palm button and footswitch available for two-operator jobs.
