Roll bending machines: all areas of application

Roll bending machines: all areas of application

Bending machines are machine tools used in the paper industry, in the metallurgical, textile and rubber production sectors. They consist of two or more rotating cylinders made of cast iron or steel: the material to be worked is passed right through the cylinders. Thanks to the bending machine, the industrial production process is given life, which takes the name of calendering, which requires a plastic deformation for which it is possible to create, transform metal profiles or sheets of material. Depending on each case, we talk about calendering of metal sheet, calendering of plastic or calendering of rubber.

How roll bending machines work

A bending machine works in a very simple way, since it is based on the change in the shape of the sheet that occurs when it bends as it passes through the rollers. To perform the calendering of plastic and rubber, reference is made to calenders consisting of rollers that rotate at reduced speeds and characterized by parallel axes whose distance is adjusted according to needs.

Among the companies in the sector active in the production of bending machines, the 1960 Seravesi company specializes in the manufacture of 3/4 roll bending machines , presses for shipyards, edge banding machines, alongside the construction of these manufacturing machines, internal design is foreseen up to testing. final with expert operators, assembly at the end customer with maximum precision and care.

Roll bending machine: the E79 AND RI72 models of 1960 Seravesi 

E79 of 1960 Seravesi

Among the production peculiarities of 1960 Seravesi stands out, among others, the E79 model, a 3 rolls bending machine with total invitation, characterized by the lower rollers with variable axes and the motorized upper roll with hydraulic vertical movement .

The 1960 Seravesi E79 series bending machines are available with capacities from 25 mm up to 300 mm and roller lengths from 1000 mm up to 6000 mm.

The invitation of these bending machines is excellent, thanks to the high thrust of the upper roller, used in this phase as a press brake. Furthermore, the lower rollers can be translated horizontally and independent of each other with a variable pitch, while the motorized upper roller translates vertically.

The fields of application of a 3 rolls bending machine are: oil platforms, the marine industry, reactors, turbines, boilers and earth moving machines.

RI72 of 1960 Seravesi

The RI72 is an integral oleodynamic drive rolling machine characterized by 4 rollers with double infeed with linear movement and with bronze guides.

The 4 rolls bending machines of the RI72 series are available with capacities from 25 mm up to 300 mm and roll lengths from 1000 mm up to 6000 mm.

Among the strengths of this model, to highlight the positioning accuracy of the rollers maintained over time thanks to the linear guide system. The lower rollers are guided inside the machine structure, eliminating the possibility of play due to wear of the machinery, as opposed to what happens on machines with planetary system (PSG ”) / levers.

Furthermore, they are easy to use, thanks to an easy accessibility of the hydraulic parts and thanks to the diagnostics present in the control panel within easy reach of the operator.

The fields of application of a 4 rolls bending machine are: oil platforms, the marine industry, reactors, turbines, boilers, earth moving machines and tankers for trucks.

After sales: the plus for an impeccable service

A plus for those who work in the world of industry and in the production of special systems such as bending machines, after-sales takes on a fundamental role. In this regard, 1960 Servasi offers a 24-hour assistance service, on the national and international territory, for new and used bending machines of Sertom and non-Sertom brands. This service also satisfies any request for spare parts, such as, for example, oil filters, maximum pressure valves, safety valves, check valves, flow control valves, solenoid valves, gear pumps, pressure switches, gaskets, gaskets for cylinders. hydraulic, PLC batteries, linear transducers, for EMO and RIMI calenders and for bending machines of all types and of any brand.

The after-sales service avails itself of the support of qualified and specialized operators, who carry out quick and efficient interventions at your premises on request. The maintenance service is scheduled , in compliance with current legislation, allowing a reliable and constant control on the machinery, in order to identify in advance the conditions of wear and anticipate the risk of inconvenience of machine downtime.
