Straight punches
General-purpose profiles for common air-bending work, selected by angle, tip radius, height and load rating.
Press brake tooling explained
The bend is only as good as the interface.
Punch profile, die opening, clamping and alignment determine bend radius, force, setup time and part quality. BENDRYX and Machinists Vault can configure new tooling or safely adapt compatible tools already in your shop.
Tooling fundamentals
Punch shape and die opening create the bend.
The correct combination depends on material thickness, desired inside radius, flange length, bend angle and available machine force.
Gooseneck punches
Relieved geometry provides clearance for return flanges, channels and previously formed features.
Acute and special profiles
Narrow or acute punches support smaller angles, hems and application-specific formed geometry.
V-opening selection
The die opening changes radius and required tonnage.
In air bending, a larger V-opening generally produces a larger inside radius and reduces required force. A smaller opening creates a tighter radius but raises tonnage and may limit minimum flange length.
- Confirm material type, thickness and tensile strength.
- Check the target inside radius and minimum flange.
- Verify tooling load rating against calculated force per metre.
- Store and handle precision tools to protect working surfaces.
Clamping systems
Faster changes with repeatable alignment.
The clamping interface secures tooling, establishes alignment and determines how quickly operators can change a setup.
Manual clamping
A straightforward solution for lower change frequency and controlled tooling budgets.
Hydraulic clamping
Fast, even clamping pressure supports frequent changes and consistent tool seating.
Automatic interfaces
Supports high-mix production and automated tool-change strategies where setup time drives output.
Adapters and safety clamps
Keep compatible tooling productive.
Replacing every tool is not always necessary. Machinists Vault can review the tooling already on your floor and engineer suitable adapters or safety-clamp solutions for a new BENDRYX installation.
- Document the existing tool style, tang, height and sectional lengths.
- Confirm load ratings and physical condition before reuse.
- Engineer adapters around the machine daylight and clamping interface.
- Add safety retention where required for handling and changeover.
Selection checklist
Specify tooling from the finished part backward.
- 01
Material
Identify grade, thickness, strength, grain direction and surface requirements.
- 02
Geometry
Review angle, inside radius, flange length, return flanges and collision risks.
- 03
Method
Choose air bending, bottoming, coining or staged forming as appropriate.
- 04
Load
Calculate force and confirm punch, die, clamp and machine capacity.
- 05
Changeover
Match segmentation, clamping and storage to the production mix.
Tooling questions
Common press brake tooling questions.
Can BENDRYX use our existing tooling?
Often yes, subject to style, dimensions, load rating and condition. Machinists Vault can review compatible tools and specify adapters or safety clamps.
How does die opening affect bend radius?
In air bending, the inside radius is influenced by the die opening and material behavior. A larger opening generally produces a larger radius.
When is hydraulic clamping worthwhile?
Hydraulic clamping is valuable when tools change frequently, setup time is critical or consistent seating across long tools is required.
Why segment press brake tooling?
Segmented tools let operators build the required working length, create clearance and handle sections more safely during setup.
