Large radius sheet metal forming.

Easy to use fast and repeatable results. 18 84955592 x 137 360. This method will have advantages over using a roller because the length of the rolled section can be controlled more precisely with high repeatability. Compared with the arc segment the forming effect of the polyline segment is positively related to the number of polyline segments.

The next step is to determine the radius pitch which is the distance between the bends or the number of steps required. Step bending large radii. 3 000 inch radius at 45 degrees. Radius forming sheet metal with custom die retainer punches and urethane forming pad in 90a durometer.

Protocase tech tip video. There are two significant factors which characterize large radius bending the first is the multi breakage phenomena and the second is an increased amount of spring back. Bend radii minimum bend sizes. Contact acrotech inc if you would like to learn.

The basic principle of the multi step forming process is to roughly divide the arc segment into polyline segments as shown in figure 1 so as to achieve the purpose of bending sheet metal with large radius with small radius punch. Our custom made die retainer holds the urethane die pad in place and punch is specifically made for your application. Step bending or bump bending is a method for forming a large bend radius in a sheet metal part without the need for special tooling by creating a series of highly open bends in close proximity.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
