Digima prism die for the AMADA press brake, 120x120x4000 mm, 200T, M16
Digima multi-groove prism die for an AMADA press brake, 120 x 120 x 4000 mm, 200T
We are pleased to present a professional Digima lower die with a four-sided design, engineered for heavy-duty use on press brakes utilising the Amada clamping system. This tool has been optimised for use with machines with a pressing force of up to 200 tonnes, enabling the precise bending of thick sheet metal whilst maintaining full process stability. Manufactured from high-grade T8A tool steel, it guarantees extreme resistance to compression and a long service life for the cutting edges, even during intensive industrial use
The die features a universal multi-groove design with a cross-section of 120 by 120 millimetres, offering the operator access to a wide range of bending channels without the need to dismantle or replace the tool. The use of such a solid profile ensures excellent die rigidity, which directly translates into high angular repeatability and the elimination of tool deformation under high pressure. Each working channel has undergone precision grinding, which protects the surface of the material being bent and ensures a clean bend line along the entire length of 4,000 millimetres.
Suitable for the PBH-200-4000 press and others of these dimensions
Technical parameters and design specifications
Below is a detailed summary of the technical specifications for the multi-row die, compiled directly from the design documentation:
Overall dimensions and tolerances of the body:
- Total length of the tool: 4,000 millimetres.
- Cross-sectional profile: a square with a side length of 120 millimetres.
- Tolerance on the external dimension: 120 millimetres, with a deviation ranging from minus 0.1 millimetres to minus 0.05 millimetres.
- Geometric precision: the error in parallelism and straightness of the die along its entire length does not exceed 0.05 millimetres.
Geometry of the bending channels and V-grooves:
- Main upper channel: a wide opening measuring 90 millimetres with side sections of 30 millimetres each.
- Main lower channel: an opening 60 millimetres wide.
- Set of side channels: the tool is equipped with a series of grooves with widths of 45 mm, 36 mm, 24 mm, 16 mm, 12 mm, 10 mm and 8 mm.
- Bending angles: all standard V-channels have an opening angle of 86 degrees.
- Working edge radii: R9 and R5 radii are used for the largest channels. The remaining edges are finished with R4, R3 and R2 radii to protect the material from damage.
Installation details and finish specifications
- Stabilisation system: the die has two mounting holes for M16 bolts, 40 millimetres deep.
- Final machining of the body: sharp edges at both ends of the die have been safely rounded off with a wide 5 by 45-degree chamfer.
- Finish of external edges: a longitudinal external chamfer on the body, type 1 at 45 degrees, applied at four points along the profile.
- Additional technical parameters: relief channels measuring 2 by 2 millimetres have been machined in the bottoms of the working channels. All channel radii not marked on the drawing are R 0.5 millimetres.
