Bending Cell: ระบบพับโลหะอัตโนมัติเต็มรูปแบบ
Bystronic has enhanced the Xpert Pro press brake to create the fully automatic Bending Cell. The Bending Cell enables users to handle large series and even changing order levels efficiently and without errors. This manufacturing solution won an MM Award at EuroBLECH 2018.
The Bending Cell fully automatically bends sheet metal parts. For this, Bystronic expands the high-end Xpert Pro press brake with an agile robotics system. A 7-axis robot picks up the sheet metal parts that are to be bent, places them with high precision on the Xpert Pro for bending, and subsequently sorts them according to jobs. The Bending Cell can handle sheet metal parts up to 270 kilograms.
With high precision, the robot also automatically sets up the press brake with the appropriate tools. To achieve this, Bystronic has integrated a tool magazine into the Bending Cell that keeps a range of required bending tools on standby. Thanks to its maximum press capacity of 320 tons, the bending automation solution can process a wide range of sheet metal products. The Bending Cell is ideally suited both for the efficient processing of high-volume repetitive jobs and for changing job lists with small batch sizes.
At EuroBLECH 2018, Bystronic received an MM Award for the Bending Cell. The expert jury consisting of the editors of the “blechnet” and “MM Maschinenmarkt” trade magazines was particularly impressed by the concept behind the new bending automation solution. In their statement, the jury highlighted the following aspects of the Bending Cell: “Jobs that previously had to be performed manually are now automated, including tool changes and transitions between jobs. This makes 24/7 unmanned production possible.”
Intelligent System for Precise Bending
Haco’s PressMaster series hydraulic CNC press brakes features a full integration of high level machine specifications, control, software, safety and tooling technology for the benefit of short set up times, high part accuracy and safe operation without compromising on productivity.
The state-of-the-art Multi Touch FastBEND-3D MT Premium control offers Automatic Tool Search during designing your part along with instantaneous calculation of bending sequence and NC program.
Precise Bending is guaranteed by:
New Standard Tooling system offers the highest accuracy and durability. Vertical loading together with the unique self-seating, self-aligning hydraulic clamping characteristics guarantee short set up times.
The machine can be optionally equipped with the ‘Smart Tool Locator’ system indicating the correct tooling position as well as the active tooling during the bending process.
Automatic AngleMeasurement and Automatic Correction of the bending Angle.
Haco PressMaster seriesoffers two alternative systems:
1) Alfa-F Angle Measurement System
A system consisting of 2 laser beam transmitters and 2 camera’s on both sides of the work piece.
This system ensures each angle is bend properly from the first bend, without the operator having to correct the angle manually to eliminate effects such as spring back and/or tolerances in material thicknesses and mechanical properties.
2) Optical Light Guard Iris Plus with Active Angle Control
Active Angle Control with Lazersafe’s Optical Safety Guardsystem IRIS Plus guarantees safe operation controlling the entire area around the top tooling, discontinuing the fast downward movement of the beam instantaneously when detecting any safety hazard in the protected area.
This optical Safety Guard IRIS Plus comprise a laser transmitter and receiver set mounted to the upper beam of the press brake. Each model includes a high speed digital camera and image data processing system contained within the receiver unit.
The data collected with the Iris Plus system is processed to compensate the unpredictable value of spring back.
This Active Angle Control is a highly accurate process that ensures prediction of spring back for each individual bend in order to obtain the correct angle from the first bend.
The symbiosis of the above technologies results in an unprecedented flexible press brake operation offering short set up times and high accuracy parts with +/- 0.1mm dimensional and +/- 20’ angle precision.
