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° |
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; |
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 |
L Shape Min. Bending Size Z Shape Min. Bending Size
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:
