Application of press brake

Choosing a specific type mainly depends on the material to be used, the type of operation, as well as the rate of output. This versatile press brake is utilized for various types of forming operations using different kinds of dies. Ordinary mold bend angle and forming mold can can be used to produce the metal plates of front, back,so we can use this press brake mold to produce panels of a computer and much of household appliances shell like the shell of air condition and washing machine.various sheet metal form piece require different forming mold.we can spend some time to watch below video which shows you various sheet metal bending designs.

The top punch of press brake is divided into two types:

integral type and segmented type

• Integrated top punch: 835mm and 415mm
• Segmented top punch: a segmentation and b segmentation

A split length: 10,15,20,40,50,100 (right horn),100(left horn),200,300=835

B split length: 10,15,20,40,50,100(right horn),100(left horn),165,300=800

Standard Gooseneck Punch

Processing characteristics:

1. The application of the standard punch in the bending is mainly the avoidance of the W direction, and the bending diagram is as follows:

2. X direction: when Xmin>4mm, it can be bent (when the size is required in the W direction)
3. Y direction:when 0<Y< 30mm, the Z direction cannot be avoided. When Y≥30mm, Z=Y-300Split graph:A split

Gooseneck Punch

Processing characteristics:

1. The application of the standard punch in the bending is mainly the avoidance of the W direction, and the bending diagram is as follows:

2. X direction: when Xmin> 9mm, it can be bent (when the size is required in the W direction)
3. Y direction: when 0<Y<85mm, the Z direction cannot be avoided. When Y≥85mm, Z=Y-85
4. Split graph:A split

Straight Punch

Processing characteristics:

1. Suitable for bending symmetrical products. Both front and rear directions can be avoided.
2. When Xmin> 10mm,W and X direction can increase in proportion.
3. When 0<Y< 20mm,Z=0.
4. When Y> 20mm, Y and Z directions can increase in proportion.
5. The bendable length in the W direction is greater than the bendable length in the Z direction.

Arrow Punch

Processing characteristics:

1. Suitable for bending symmetrical products, both the front and rear directions can be avoided,

and the bending opening can be as small as 6mm.

2. When X< 50mm,Y<50mm,W and X direction can increase in proportion.

Acute Punch

Processing characteristics:

1. Applicable range is between 30° and 180。
2. Use a small angle of the tip of the tool to avoid the tapped hole and other work pieces that need to be avoided.
3. It is used for deep bending, and the insertion depth is suitable for bending angle as shown in .the following fgure:

Acute Punch II

Processing characteristics:

1. Suitable for angles between 45 and 180
2.  Use a small angle of the tip of the tool to avoid the tapped hole and other workpieces that need to be avoided.
3. bending angle as shown in .the following figure:

Radius Punch

Processing characteristics:

1. Radius punch is often used as bends for the upper cover
2. Sometimes used for shaping the workpiece with a small angle.

Split graph:B split

Large Radius Punch

Processing characteristics:

1. this large radius punch is mainly used for bending the inner arc angle of R,and the radius of the arc angle  is R3-R10

2.The radius punch is matched with the corresponding V groove

1.Hemming Punch

Processing characteristics:

1.1  The figure diagram shows the shape of the product after bending and flattening. All similar shapes can be bent. It should be used with 30° upper and lower molds.

2.2 The radius punch can also be used for pressing,riveting,shaping,etc

2.Offset Punch

Processing characteristics:

1.1 used for Z bending which can’t be folded by common press brake dies . H=1-10mm

2. 2 The shape of the bend product is as shown in the upper right figure, usually called Z bend or offset.

Also press brake are widely used in Heavy equipment manufacturing industry
