How to bend an arc with a press brake?

Bend the arc on the press brake machine. If there is no arc blade, you can use the die with small V mouth of the upper die.

First draw a line and fold it according to the scribed line, so that you can fold out an arc.

When there is no mold, it is still possible, just a little more complicated.

First calculate the arc length, chord length, arc height and center angle of the workpiece, and then divide and scribe according to these data. At the same time, control the stroke and pressure, so that the arc can be folded from both ends of the arc to the arc height, so as to process the arc.

Here are the specific steps:

1. As shown in the red circle in the figure, put the place where you want to bend the arc under the press brake machine.
