2. Punches
In contrast to dies, punches are used to exert force on the material while it is being bent. Depending on the kind of bend that is needed, punches come in a variety of sizes and forms. Hemming punches, single V-punches, and multi-V-punches are common punch types. To get the proper bend, punches are usually used in conjunction with V-dies.
- Function: Produces a bend by applying force to the material.
- Frequently Used: For precisely and carefully bending sheet metal.
- Benefits: Comes in a range of sizes and forms to accommodate varied bending degrees and materials.
3. Specialty Tooling
Custom tooling made to satisfy, intricate, or unusual bending needs is known as specialty tooling. Tools made for certain materials (such as heavier metals or materials that are difficult to bend) or for specialized tasks like punching, notching, or creating complex shapes can fall under this category.
- Function: Made to do bending jobs that are beyond the capabilities of conventional tools.
- Frequently Used: For extremely specialized or difficult applications.
- Benefits: Offers customized solutions for certain manufacturing requirements, increasing accuracy and flexibility.
4. Gooseneck Tooling
Deep bends or pieces with narrow interior radii are bent using gooseneck tooling. These tools include a characteristic gooseneck shape, allowing the punch to reach portions of the material that are difficult to access with standard tooling.
- Function: Provides access to difficult-to-reach places, enabling deep or tight bends.
- Frequently Used: For intricate, very precise tasks like creating deep bends.
- Benefits: Increases bending flexibility without sacrificing material integrity.
5. Folding Tooling
The purpose of folding tooling is to bend sheet metal without producing a large bend radius. These tools are employed in folding operations, which are often used to create boxes or enclosures, where the metal is bent so that the material folds over itself.
- Function: Enables a folding action without the formation of a conventional bend.
- Frequently Used: Often used in the construction of boxes or enclosures and pieces that don't have sharp edges.
- Benefits: Increases material efficiency by enabling complex folds and low-radius bends.
