Press Brake Tooling (Bending Machine dies) Guide
Press brake tooling are dedicated forming tools paired with bending machines. As core parts for sheet metal bending, they consist of upper and lower tooling. When the machine slide moves against the worktable, metal sheets get pressed between two tooling. The material bends into set angles and shapes like right angle, U shape and V shape. These tooling serve widely in machinery manufacturing, sheet metal fabrication, hardware and cabinet making. We supply solid CNC press brake tooling and practical bending solutions for daily production.
Core Parts & Working Principle
Upper Tooling
It fixes on the moving slide and acts as the pressing part.
Different designs including straight edge, sharp corner, gooseneck and arc decide the final bending shape. We supply tough 4140 press brake punches for long time stable use.
Lower Tooling
It stays fixed on the worktable to hold work pieces.
V type groove is the main structure. Groove width directly affects bending force, corner size and finished appearance.
How It Works
Lay metal sheet flat on lower tooling
Upper tooling presses down steadily
Material forms permanent bend following tooling contour
Stop pressing once reaching required depth and pressure
Lift upper tooling and take out finished product
Product Features
-
Strong rigidity and wear resistance
Made from 42CrMo press brake tooling. Treated with quenching and tempering, hardness reaches HRC45 to HRC50. The tooling stand frequent squeeze and friction without easy damage.
-
Flexible custom service
We make gooseneck punch and V tooling, arc and special shaped tooling. Common groove sizes cover 8mm, 16mm and 24mm to fit sheets of different thickness.
-
Good fitting performance
All tooling match well with machine clamp structure, slide travel and standard pressure load. Dimension strictly follows actual processing drawings.
-
Standard and serialized specs
Regular tooling fit mainstream bending machine brands. Custom CNC press brake tooling are available to meet special production demands.
Common Product Types
Classed by bending shape
Straight edge tooling: Basic choice for regular flat bending
Sharp angle tooling: Used for narrow angle bending and springback adjustment
Gooseneck tooling: Ideal for deep U groove work, avoids collision during processing
Arc tooling: Makes round corners and curved parts
Special shape tooling: Produced according to customer drawings
Classed by processed material
Standard sheet metal tooling: Suits low carbon steel and galvanized steel, cost effective
High strength steel tooling: Thickened body fits stainless steel and hard alloy plate
Thin plate tooling: Fine machining prevents scratch, warp and deformation
Classed by installation style
Amada style press brake tooling: Compatible with Amada and Promecam equipment
Trumpf & Wila type: Matches corresponding brand bending machines
Universal standard type: Works with most local bending devices
Practical Tooling Selection Tips
1. Match raw material property
Mild steel bounces slightly. Use 86° to 88° punch for standard 90 degree bend.
Stainless steel and high strength steel have obvious rebound. Choose 85° punch to correct angle deviation.
42CrMo press brake tooling is the mainstream material, balanced toughness and hardness after heat treatment.
2. Follow 8 times thickness rule
Sheet 3mm to 8mm thick: V groove width equals 8 times material thickness
Sheet under 3mm: Set groove width as 6 times thickness for neat small corner
Sheet over 8mm: Adopt 10 to 12 times thickness, cut down bending force to protect tooling
3. Keep safe pressure range
Calculate required pressure based on material thickness, tensile strength and groove size. Leave 10% to 15% safety margin, never run press brake tooling over rated load. Use thickened or split tooling for thick and hard plates.
4. Pick proper punch style
Standard punch handles common bending jobs. Sharp angle punch fits precision angle work. Gooseneck punch and V tooling suit deep groove parts. Arc and irregular punches apply to curved and special shaped work pieces.
5. Check machine compatibility
Select matching mounting type including Amada style press brake tooling, Trumpf type and universal standard type. Confirm tooling height and slide travel before installation for smooth assembly and precise positioning.
Daily Use Notes
Take material springback into account to keep accurate bending angle.
Stick to thickness matching rule to avoid plate crack and tooling breakage.
Verify installation size to prevent assembly problems.
