The bending die typically consists of components like the intermediate plate, upper die, lower die, guide rails, and lower die seat, offering strong versatility to handle a wide range of machining tasks.
Selecting the appropriate bending die is crucial for processing different parts. Understanding the machining parameters of the machine tool and die is essential to ensure a compatible die selection.
Machine tool parameters such as stroke, processing capacity, open height, and intermediate plate type, along with die parameters like upper die shank type (matched with the intermediate plate) and pressure tonnage (maximum bending pressure), play key roles in die selection.
In terms of machine tool parameter selection:
- Choosing the die height involves calculating the stroke based on various heights to ensure proper alignment for different machining needs.
- Different combinations of dies yield varying die heights for processing different parts effectively.
Regarding die parameter selection:
- The upper die shank comes in three forms to match different intermediate plates.
- Common standard upper die shapes include various tip radii like 0.2R, 0.6R, 0.8R, 1.5R, and 3.0R, with suitable choices based on the material thickness.
- Standard upper die tip angles include 90°, 88°, 86°, 60°, 45°, and 30°, ensuring the die angle is slightly less than the bending angle for precision.
Different types of lower dies, such as single V and double V, with segmented or solid variations, cater to diverse machining needs. Generally, the versatility of single V dies surpasses that of double V dies, with segmented options being more versatile than solid ones. Our company typically employs double V and triple V lower dies, ensuring efficient processing based on material thickness and die angle alignment with the upper die.
