In the bending operation of the bending machine, the following types of molds are usually required:

Standard upper die and lower die:

The standard upper die is usually used to press the sheet into the lower die to create the desired corner.

The lower die is used to support the sheet and works with the upper die to complete the bending process.

Sharp knife die:

The sharp die is used to bend smaller angles and sizes, allowing for more accurate acute angles.

It is suitable for applications where high precision bending is required.

Large bending mold (Gooseneck mold) :

Large bending dies, also known as gooseneck dies, are used to bend large angles, usually for bending "U" shaped products.

This mold provides greater flexibility to meet complex bending requirements.

Flattening die:

The flattening die is mainly used for the operation of the dead edge, and is used in conjunction with the sharp die.

The workpiece is first bent to an Angle of less than 45° with a sharp die, and then pressed to a dead edge with a flattening die to enhance the reinforcement effect of the border.

Break differential mode:

The break die, also known as the "Z" die, is used for the one-time bending of small size "Z" workpieces.

This mold can improve production efficiency and ensure bending accuracy.

Forming die:

Forming die including arc die, door frame molding die, U forming die and so on.

These molds are used for more complex product bending and can meet the needs of a variety of bending angles and styles.

Same core mold:

The same core die usually refers to the lower die used in the matching CNC bending machine, which is composed of the die support and the segmented lower die.

Using the same core mold can easily change the mold and improve the machining accuracy.

In addition, the material of the bending machine die is also very important, usually using 42CrMo, Cr12MoV(SKD11), T8A, T10A, 9CrSi and other high-quality die steel manufacturing. These materials have high wear resistance and toughness to meet different bending needs.

In general, the bending machine needs a wide variety of molds, the specific choice of molds depends on the specific needs of the product and the type of bending machine. When choosing a mold, factors such as the thickness of the plate, the required bending Angle, and the shape and size of the product should be considered.
