Press brake with automatic tool changer
- Published: March 16, 2017
Amada's new HG ATC press brake with automatic tool changer was designed as a solution for variable lot sizes to eliminate costly delays associated with manual tool setups, says the company.
The patented Automatic Tool Changer (ATC) with patented Amada tooling can load the most complex tool setups within three minutes and allows operators of varied experience levels to efficiently utilize this bending system.
Quick tool setups achieved by the ATC gives users the ability to seamlessly introduce rush jobs and triple or quadruple the amount of setups performed each day.
Depending on the HG ATC model, the ATC is capable of storing up to 112.8 ft of patented, high-precision tooling and is equipped with four tool manipulators that place punches and dies along the length of the press brake. Additionally, tooling can also be installed in reverse orientation.
Other standard features on the HG ATC include an AMNC 3i Control, an integrated bend sensor (Bi-S) that guarantees consistent bend angle accuracy, and a servo/ hydraulic drive system that consumes less energy than a conventional press brake.
Many factors were considered in the engineering of Amada's Modular Tooling System (AMTS) — including tool balance, verticality, and acute tolerances. In addition to the standard requirements of press brake tooling, Amada's patented tooling design accounts for motion during loading/unloading and accurate punch tip alignment, which is magnified depending on the height of the tool. All of these crucial tooling characteristics were thoroughly tested and attained by leveraging new tool manufacturing methods to ensure accurate, repeatable, and rapid tool changes with the ATC.
The ATC can load the most complex tool setups within three minutes. Full tool stockers of 100 mm tooling can easily be loaded at once to further decrease setup times for long parts.
Amada's latest control features an easy-to-use graphical interface that minimizes the learning curve and maximizes machine productivity.
Other key features include:
- Bi-S - Bend Indicator Sensor with automatic detection and compensation of material springback. It eliminate test bends and reduce setup. An automatic angle adjustment ensures high quality production bending even when material thickness and hardness varies from part to part. It's compatible with 1V-dies (0.236 – 1.57 in.)
- Dynamic hydrdaulic crown bed: Hydraulic cylinders located in the lower beam of the machine automatically compensate for any ram deflection and achieve consistent bend angles throughout the entire length of the machine. Operators can program a complete workflow by staging multiple tool setups along the bed. Model HG 1003 ATC has two hydraulic crowning cylinders and HG 2204 ATC has three Hydraulic crowning cylinders
- Multi-axis backguage is equipped with L-shift functionality to gauge complex part geometries. High speed movement on all axes ensures the gauge fingers are positioned as quickly as the operator positions the part. Positioning repeatability is +/- 0.0001 in.
