Rolling Radius On Sheet Metal Edge

Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

Rolling radius on sheet metal edge.

It is better to leave a small radius inside the hem. Still some advice applies. Therefore the bending inner radius of our sheet metal parts is basically 0 2. Of jamey jordan series 5 8 inch radius rolls allows you to make a full 90 degree radius bend on the edge of sheet metal.

Good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry. For ordinary low carbon steel plates rust proof aluminum plates brass plates copper plates etc the inner radius 0 2 is no problem. Completely crushing the radius needs great power and tonnage. This is perfect for forming.

Visualize if you will rolling the edge of a piece of paper. Sheet metal locking crimpers. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. Turn your impact driver into a power crimper and create raised edges on sheet metal more quickly than hand crimpers.

Jamey jordan radius roll set 5 8 inch radius. Create a raised edge in sheet metal that locks into the rolled edge of another piece. This is because the metal is simply being bent on one plane. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

The smaller radius is formed first to allow the material to finish inside itself. No stretching or compressing is needed to achieve this shape. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. If you want to strengthen the edges of your metal sheet hemming is a great option.

Leaving a radius on the other hand relieves this danger. The desired radius is created by step bending a progressively larger radius into the sheet beginning with the desired curl radius minus the material thickness and ending with the desired curl radius.
