Bending machine dies are tools used in bending machines to bend and shape metal sheets during processing. Bending machine dies are usually made of high-strength alloy steel or other special materials, with high wear resistance and durability.

Bending machine dies usually consist of an upper die and a lower die. The upper die is fixed to the upper part of the bending machine, and the lower die is fixed to the lower part of the bending machine. During operation, the metal sheet is placed between the upper die and the lower die, and the upper die and the lower die are contacted and pressure is applied through the operation of the bending machine, so that the metal sheet is bent and deformed.

The design and selection of bending machine dies depend on the material, thickness, and required bending shape and angle of the metal sheet to be processed. According to different needs, bending machine dies can have various shapes and curves.

Bending machine dies are widely used in the metal processing industry, and are commonly found in metal manufacturing, automobile manufacturing, aerospace, machinery manufacturing and other fields. They play a key role in the precise control and shape forming of metal sheets, helping manufacturing companies achieve efficient and precise production and processing.
