Sheet metal should be bent at the minimum bend radius possible.
Punched bent sheet metal frc.
When we air bend sheet metal the size of the die v opening determines the inside radius of the bend.
The punch tip radius usually has little influence.
Minimum punch radius 63 of the material thickness.
Troy products is a subsidiary of troy sheet metal works inc.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
With bottoming the inner radius of the angled sheet depends on the die s radius.
The metal forms to a natural radius based on the size of the die v opening.
As with any mechanical parts cutting and shaping process sheet metal punching can create sharp edges and burrs from time to time.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
Using rotational dies the punch secures the perforated sheet as it initiates bending just as with tread plate.
Another way of strengthening the sheet metal is by punching holes and slots.
Troy products focuses on products geared toward public safety vehicles and similar apparatus.
Material bend radii and minimum bend size charts please note.

Bottoming is also known as bottom pressing or bottom striking.
In principle does not seem that this operation is complicated and difficult.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
Hillman 12 in x 24 in cold rolled steel expanded sheet metal.
As the name bottom pressing suggests the punch presses the metal sheet onto the surface of the die so the die s angle determines the final angle of the workpiece.

Does this mean that one size punch tip radius will work well with every application.
Metal of extremely high tensile strength may move regardless but in most situations as long as the clamping pressure is adequate to overcome the resistance your bend will be accurate wold said.
