tl;dr - Not without a little work to reconfigure the 3-in-1 for this particular part.
3-in-1 machines like we have in the metal shop can be configured for box and pan work, or outside flanges, but without a segmented die, they don’t work well for internal flanges. A segmented die on a press brake, or using an apron brake, a segmented apron allows an internal flange to be made. So, as it is built, no, the brake in the metal shop won’t work.
However, a separate die could be made to straddle the existing die. The punch will do as is (mostly, more on that later) because the main part of the material would be be pushed away from it. That isn’t particularly hard to make, especially for a light part like you have. Typically a punch and die made of mild steel would be fine for light duty or low volume parts. If you want to get into making thousands, tool steel is required as the punch and die will wear out eventually.
The other part of the equation is clearance for the part. Whatever you are bending has to have room for the unbent part to be positioned and for the bent part to bend into. There is little above the die to get in the way on an open part like this. However, because this is a 3-in-1, the shear has to have a truss to keep from deflecting while shearing material. This truss can be seen going across the back side of the shear blade. Across the front is the bed of the shear that the material being sheared would rest on while being sheared. Depending on the order of operations many parts can still be bent on a 3-in-1 keeping in mind that the material can’t occupy the same space as the tool.
In the case of this part, the acute angle is hard to do on the 3-in-1 as it sits because the existing punch and die will not support bends beyond 90 degrees (or close to it). Couple that with the internal flanges and I would probably try to bend this a different way. How many do you intend to make? For a prototype, I would be inclined to make a punch and die that can be placed on the existing die and in place of the existing segmented punch. That could be made to bend up or down, depending on how you order the operations. If you think the bending is pretty close to what the final product will be, you could make dies to do all of the flanges in one stroke, and then bend the W shape in a second or second/third operation. Not terribly difficult to do, but it does require some materials and time.
