Hemming Bending Solutions
Hemming can eliminate sharp edges and burrs of the product, another advantage is the thickness of product can be increased with the hemming of edge and strengthen the final product.
Advantage: production of the hemming area in two strokes; active components are hardened.
Hydraulic Hemming Bending
Controlled via hydraulic cylinders, can hem various material thickness and weights
Spring-loaded Hemming Bending
The dies adopt the structure with polyurethane insert, which can completely eliminate the marking on the outside of the product, but the bending angle is difficult to control. So it is only suitable for bending products with low bending dimensional accuracy.
Pneumatic Hemming Bending
The structure of the Rolla-V die is changed from a fixed overall V-groove structure to a symmetrical left and right rotating flap, so that the product does not slide relatively to the left and right rotating flap during the bending process.
The advantages of the Rolla-V die:
★ Modular structure, precision manufacturing and high tooling precision;
★ Avoid mark on the workpieces;
★ Bending the laser-cut sheet without causing damage to the tooling;
★ Short flange bending;
★ Bending around holes and grooves without deformation.
U- shapedH Hemming Bending
A combination of punch and die that can be used for both pre-bending and closing.
