Roll bender: characteristics and types for sale

When we talk about roll benders we refer to hydraulic industrial machinery called sheet metal calenders, that is, roll benders used for bending pipes and ducts. They are machines capable of bending a metal bar into a circular arc. These roll benders are available in two types depending on the number of rollers they are made of. There are three rollers and four rollers. So in this specific case we are talking about: 3 Rolls Plate Bending Machine and 4 Rolls Plate Bending Machine.

Let's see in detail the characteristics of the roll benders and what types of roll benders are on the market:

Calenders for sheets with 3 rolls

The 3 Rolls Plate Bending Machine , also called E79 from 1960Seravesi, is a CE certified three-roller hydraulic rolling machine composed of lower rollers and an upper roller with hydraulic vertical movement. The 3 Rolls Plate Bending Machine is available with capacities from 25mm up to 300mm and roll lengths from 1000mm up to 6000mm. Thanks to the high thrust of the upper roll, the 3 Rolls Plate Bending Machine guarantees an excellent quality pre-crease. Furthermore, the lower rollers move horizontally and are independent of each other while the motorized upper roll moves vertically.

The 1960Seravesi E79 roll bender, thanks to its small size, is a compact machine and ideal for medium and large thickness bending. This type of roll bender is also suitable for bending thin sheets to create small diameter tubes. Just decrease the distance between the reels and that's it. In practice, owning such a  versatile 3 Rolls Plate Bending Machine is like owning two machines in one. We are talking about a roll bender that is absolutely simple to use and extremely reliable for the safety of the operators, as it is equipped with an emergency button capable of stopping the machinery at any stage of processing.

The rollers are made of forged and hardened special alloy steel or carbon steel. The radial bearings are mounted on all rollers of the roll bender and the cylinders are fitted with excellent quality gaskets. The lubrication system is top of the range being equipped with a pump with autonomous tank programmable from the touch panel.

4 roll calenders for sheet metal

The 4 Rolls Plate Bending Machine, also called RI72 from 1960Seravesi, is a CE certified 4 roll bending machine with hydraulic drive with double pre-bending. The 1960Seravesi RI72 series roll benders are available with capacities from 25mm up to 300mm and roll lengths from 1000mm up to 6000mm.

The 1960Seravesi RI72 roll bender is easy to use and keep in perfect working order thanks to the easy accessibility of the hydraulic parts and the diagnostic lights on the control panel. The operator, therefore, will always have an eye on the operating status of the machine in order not to encounter problems of any kind.

In addition to the safety, speed and reliability of the 1960Seravesi RI72 roll bender is given by the positioning accuracy of the rolls which remains stable and unchanged over time thanks to the linear guide system that eliminates the possibility of play due to wear of the roll. bender.

We are talking about a roll bender whose precision and reliability derive from over fifty years of experience in the construction of hydraulic machines. A roll bender of exceptional strength given by the electro-welded steel crosspieces subjected to normalizing heat treatment. Furthermore, the cylinders are made of alloy steel and carbon steel with chromed rod and use seals of unsurpassed quality.
