Plate Bending Machines 1960 Seravesi

Plate bender: discover the technical characteristics

A plate bender is an industrial machine that uses hydraulic power to carry out sheet bending and rolling different types of sheet metal into a circular or conical shape.
A plate bender, which we could also define as a "plate bender" or "calender for sheet metal", can be used in various industrial sectors and its manufacturing models differ according to the rollers of which the plate bender is made.

There are 3-roller plate benders and 4-roller plate benders , each with different technical specifications. So let's go now to see the main characteristics of plate benders.

3-roller plate bender (model E79 from 1960Seravesi)

The 1960 Seravesi model E79 3-roller plate bender is a CE-certified three-roller plate bender consisting of lower rollers and an upper roller with hydraulic vertical movement.

The 1960 Seravesi 3-roll plate bender model E79 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 roller, the 1960 Seravesi model E79 3-roller plate bender guarantees an excellent quality pre-fold. Furthermore, the lower rollers move horizontally and are independent of each other. The motorized upper roller, on the other hand, moves vertically.

The 3-roll plate bender model E79 from 1960 Seravesi , thanks to its small size, is a compact machine and ideal for medium and large thickness bending. This type of plate bender is also suitable for bending thin plates to create small diameter tubes . We are talking about a plate 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 every most delicate moment of processing.

The rollers of the plate bender model E79 of 1960 Seravesi are in special forged and hardened alloy steel or carbon steel. Radial bearings are mounted on all rollers and cylinders are fitted with excellent quality seals. The lubrication system is top of the range as it is equipped with a pump with autonomous tank programmable from the touch panel. Obviously, in the event of a breakdown, each component of the machinery can be replaced in a very short time thanks to the development of e-commerce for spare parts of industrial machines.

4-roller plate bender (model RI72 from 1960Seravesi)

The 1960Seravesi model RI72 4-roller plate bender is particularly suitable for calendering work. It can be equipped with two to six pumps for maximum linear and rotational thrust. A multi-pump system guarantees, in case of pump failure, an infallible operation of the machine even at reduced performance.

The crossbars of the 1960Seravesi model RI72 4-roller plate bender , as well as the support frames for the roller movement cylinders, are made of electro-welded steel and subjected to normalizing heat treatment. The rollers are made of special carbon steel and their rotation system is formed by two coupled hydraulic motors and two planetary gearboxes mounted directly on the rollers.

Linear potentiometers are mounted on each roller of the 1960Seravesi model RI72 model plate bender to allow electronic control of the parallelism between the rollers. The cylinders are made of alloy steel and carbon steel with chromed rod and use seals of primary brands, while the hydraulic unit is composed of a motor pump unit, solenoid valves and maximum pressure valves that guarantee overload protection .

By analyzing the characteristics of the 1960Seravesi RI72 model 4-roll plate bender, it is possible to understand what the right model is for specific industrial jobs. It is a powerful machine whose maximum efficiency is able, thanks to a hydraulic opening handle , to allow the removal of the product tube in a horizontal position.

In addition, the 1960Seravesi model RI72 4-roller plate bender is equipped with an automatic centralized lubrication system with pump equipped with an autonomous tank, programmable from the touch panel. Another feature of fundamental importance is the modem to remotely control the PLC in the event of software changes to immediately resolve machine failures. Also worth mentioning is the independent SIEMENS KTP1200 PN Touch Panel control with 12 ”color touch screen display.
In practice, it is possible to view on the display the position, the balancing of the rolls, set and read the inclination of the rolls, set the speed (two rotation speeds), the diagnostic functions and the machine alarm.

These were the main technical characteristics of the 1960Seravesi plate bender models that we invite you to contact at any time to learn more about the peculiarities of their plate benders.
