Sheet Metal Brake

For a while I have been planning to make a sheet metal brake that could bend parts up to 125 cm wide that is the common

well done!!! how is it holding up with deflection in the top beam?
what size angle did you use?

At first I did not make the adjustable preload bar on the top beam and then there was a slight deflection problem. After adding the preload bar the deflection is no longer a problem. Mostly I need to bend materials with thicknesses of 0,8 - 1,2mm, occasionally 1,5mm. For thicker materials I have this small hydraulic bender but the max. width is only 160mm.



The angle bar is 100 x 100mm with a material thickness of 10mm. It is strengthened with a 80 x 8mm flat bar welded to the bottom of the top beam angle as you can see from one of the pictures.

The bed is made of a U-bar 60 x 140mm with an average material thickness of 8mm. The moving bending angle is 80 x 80mm with material thickness of 8mm. It is also strengthened with a 80 x 8mm flat bar.
