The Essential Guide to Press Brake Dies: Types and Uses

What is a Press Brake die?

Metalworking dies play a crucial role in industrial production. They are indispensable tools in the manufacturing process and find widespread applications in various fields such as automotive, electronics, aerospace, and more. The design, manufacturing, and application level of dies directly affect product quality and production efficiency. Therefore, in-depth research and exploration of the diversified applications of metalworking dies are highly important.

A bending die is a tool used in metalworking, specifically designed to bend metal materials into desired shapes on a press brake or bending machine. They are typically made of wear-resistant alloy steel and possess specific shapes and dimensions to accommodate the bending requirements of different shapes and sizes of metal parts. The primary function of bending dies is to provide support and positioning, ensuring the stability of metal materials during processing and ensuring the accuracy of the desired bending angles and shapes.

What are the types of press brake dies?

There are various classifications of dies, generally categorized based on their roles in the machining process as upper dies and lower dies. Upper dies are primarily used for pressing, cutting metal materials, and other machining operations, while lower dies are mainly used for supporting and positioning metal materials to ensure stability and precision during processing. In metalworking processes, the main machining functions are performed by upper dies. For example, sharp cutting dies are used for cutting metal sheets, arc dies are used for forming bends or arcs, and bending dies are used to bend metal materials into desired shapes. Forming dies are also commonly used as upper dies to stamp metal sheets into specific shapes, such as automotive body panels. Correspondingly, the role of lower dies is to support and position metal materials to ensure stability and precision during processing. Lower dies come in single-V, double-V, and multiple-V types, with different shapes and structures to handle various shapes and sizes of metal materials. By providing support and positioning for lower dies, it is possible to effectively control deformation and errors during metalworking processes, thus improving machining accuracy and quality.

Specific types of upper dies

Shearing dies: Shearing dies are widely used in the cutting and stamping processes of metal materials. In addition to general stamping parts, they can also be used for cutting non-metal materials such as plastics and rubber.
Arc dies: Arc dies are essential for forming curves and arcs in metal materials. They are used not only for automotive body surfaces but also for areas requiring curved parts such as furniture and architectural structures.
Bending dies: Bending dies play a crucial role in sheet metal bending and are commonly used in various industries such as aerospace and construction, which require manufacturing parts with irregular curves and angles.
Forming dies: Forming dies are widely used in industrial fields such as automotive manufacturing to stamp metal sheets into various specific shapes of parts, such as body parts and engine parts.

Specific types of lower dies

Single-V dies: Single-V dies are commonly used for processing metal materials with simple shapes, providing basic support and positioning functions suitable for simple stamping and cutting processes.
Double-V dies: Double-V dies offer higher precision and stability than single-V dies and are suitable for occasions requiring high-precision processing, such as manufacturing precision equipment parts.
Multiple-V dies: Multiple-V dies provide greater flexibility and can adapt to the processing needs of complex-shaped metal materials such as pipes and profiled materials. They provide more support points to ensure the stability and precision of materials during processing.

The Difference and Characteristics between Single and Multi-Purpose Dies

Single Dies

Strong specificity: Single dies are designed for specific machining tasks and can usually only accomplish a single function or process for a particular shape.
Relatively lower production efficiency: Each die can only perform one or a limited number of machining tasks, requiring the replacement of different dies for different processes, thus leading to lower production efficiency.
Relatively lower cost: Due to their singular function, the manufacturing and maintenance costs of single dies are relatively lower.
