China Rolla v dies is a newly press brake V dies for  no marking bending.Sheet Metal Rolla V Tooling for press brakes creates bending dies that won't scratch stainless steel and aluminum. These spring-loaded Rolla v press brake die are easy and safe to use. They're designed to resist distortion or damage when bending flanges.

Principle:

The roll v die also called wing bend tools,because when bending ,the two flap plates like wing flaps.

The Rolla Vee Die is a unique bending tool equipped with two partially rotating metal pads positioned at the top of the die Rolla. It works by using the press brake punch to press the metal sheet while the pads rotate the workpiece. This tooling accommodates various styles including American style press brake tooling, European-style tools,  and Willson. Rolla V Dies. Rolla V press brake tooling is highly regarded for bending small edges without leaving marks

Configuration：

The rolla v die is consist of  tooling body,two flaps ,spring and pin.

The tooling body is made of 42CrMo,its hardness is HRC50-52°.

The flap is made of Cr12Mov,the hardness is  HRC55-58.

What material is it suitable for using

1.Stainless steel plate bending

2.Copper Plate Bending:Bus Bar

3. Galvanized sheet metal bending

4.Aluminum sheet bending

5.Mirror-finish stainless steel bending

6.Ribbed anti-slip plate bending

7.Copper sheet bending

8.Aluminum starry sky panel bending

9.Sandblasted steel plate bending

10.Aluminum-zinc alloy coated sheet bending

These sheets are commonly used in construction and manufacturing industries for various applications such as roofing, wall cladding, and piping due to their excellent corrosion resistance and weathering properties.

Advantage:

1.high precision grounded

2.Assures parts can be swapped without a problem

3.Perfect alignment reduces marks on metal sheets

4.Even close edges bend without leaving marks

5.No contamination from tools when bending galvanized or aluminum sheets

6.Precise edges, even near holes, without distortion

7.Fewer tool changes needed

8.Great for bending diagonal or tapered edges
