Press Brake Die With Rollers

In traditional press brake bending dies, sliding friction occurs between the sheet metakl work piece and the die's groove during bending. This friction can cause scratches on the outer surface of the work piece. The smaller the bending radius, the more severe the scratching tends to be.

How to bend without marks with press brake?

There are 3 ways for press brake bending without mark.

One is press brake tooling with film.

One is press brake rolla v die.

One is press brake tooling with rollers.

Press brake die with rollers is a special tool used in press brake machines to perform bending operations on metal sheets. Unlike traditional dies, which have fixed surfaces, roller dies incorporate rollers that can rotate. These rollers reduce friction between the die and the  sheet metal work-piece, which can provide several benefits in metal forming processes.

Benefits of press brake tooling with rollers

Reduced Friction: The rollers minimize friction between the die and the metal sheet, reducing wear and tear on both the tool and the material.

Improved Surface Finish: Lower friction results in a smoother surface finish on the bent metal.

Extended Tool Life: Reduced wear on the die prolongs its service life, making it more economical over time.

Reduced Marking: Rollers decrease the likelihood of tool marks on the workpiece, which is particularly beneficial for aesthetic applications.

Increased Accuracy: Consistent bending results due to reduced material deformation during the bending process.

Applications:

High-precision bending: Ideal for applications where tight tolerances and high surface quality are critical.

Sensitive materials: Beneficial for materials prone to marking or scratching, such as aluminum or pre-painted metals.

Production efficiency: Suitable for high-volume production due to the extended tool life and reduced maintenance needs.

Aesthetic Components: Ideal for parts where surface finish is critical.

Thin or Delicate Materials: Helps in reducing damage or marking on the workpiece.

How to choose the press brake low die with rollers?

The roller rotates when bending ,rolling friction between the outer side of the product and the roller is very small.So scratch marks are significantly reduced after forming. And the roller is made of high hardness material, which greatly improves the service life of the mold.
