Title: diy press brake
Post by: Andrew Wildman on August 16, 2015, 02:34:41 PM
I have a number of project updates.  The first project is a diy press brake.  I was fed up of using the hammer and vice method of folding sheet so I purchased some 20X100 plate from a local fabricator and build a press brake to fit in my 20T press.

Beautiful work.  That should be really handy.

Is punch/die combination bolt-on business? There seems to be extra hardware under the die.

The punch *(upper bit) is one piece but the die* (lower bit) is a bolt on part so that I can change it to better suited for smaller bends.

* probably not correct terms!

Hi there Andrew,

Is that miller an Elliott, the table apron and base configuration looks similar to mine...

If it is, what model is it please...

mill is an omnimil 01 based on a U2 with an Elliott/victoria turret head.

Handy machine but could do with a rebuild.  when I bought it the power down feed on the head was bust so rebuild that  (may post some pics when I find them)

Looks a nice piece of sturdy kit, I would venture more rigid than a Briddy.

Pictures would be welcomed, I had to make a cross feed nut for mine several years ago, sadly no pics though...

** Indeed, the correct terms, despite the fact that many in the metal fabrication business indiscriminately refer to both the upper and lower chunks of shaped metal as "the die".  I've had funny looks when I mention anything about a "punch", even though most catalogues and technical publications use these terms.

This design, couldn't be adapted for a shear as well? *just thinking*

two pieces of O1 tool steel with a 45 degree on one side and a straight on the other mounted to a "jig" that can be fitted between the bending die and the head. you dont need more than 2mm clearance.. unless you want pieces of steel flying, and u wanna cut something thicker.
