Introduction of bending tools and points of attention when formulating bending technology:

1. Classification of bending tools:

1. Upper die:

Tooling Type  Function and Usage
Straight knife Processing angles greater than or equal to 90°
Gooseneck Knife 
Processing angles greater than or equal to 90°
Acute Knife  Processing angles greater than or equal to 30°

Gooseneck Knife

2. Down Die 

Tooling Type 

Main Usage 

Singe V Die  1. When the V-shaped angle is equal to 88° (reference value), it can be bent equal to or greater than 90°Angle;
Double V Die 1. When the V-shaped angle is equal to 88° (reference value), it can be bent equal to or greater than 30°Angle;

Press Brake Single V die and Double V die

3. The division of the bending tool:

Under normal circumstances, the standard length of the tool (upper and lower die) is 835mm; to facilitate the bending of different lengths, the entire tool is often divided

The following paragraphs: 10+15+20+40+50+ 100+ 100+200+300=835mm

4. The relationship between the thickness of the plate and the width of the lower die groove (generally the groove width is 6 times the thickness of the plate):

Plate Thickness  Below 0.6mm  1.0mm 1.2mm 1.5mm 2.0mm 2.5mm 3mm
Lower die Slot width 4 6 8 10 12 16 18

In special cases, if you want to use small slot bending, you should increase 0.2mm per knife.

5.Minimum bendable size (bending size including plate thickness):

General minimum bendable size: L-shaped groove width / 2+ plate thickness

Z type

Slot width/2+2*board thickness

Reference:

Material Thickness Below 0.6 1.0 1.2 1.5 2.0 2.5 3.0
L Shape Min. Bending Size 4 4.5 5 6 8 10.5 12
Z Shape Min. Bending Size 5 5.5 6 8 10 13 15

6. U-shaped bending:

The U-shaped bend should use a machete. At present, our commonly used machete is divided into small, medium and large:

U-Shaped Bending

7. U-shaped bending size range
