Plate bending machine: choose the right model for your industry

A plate bending machine is a plate bending machine, i.e. a hydraulic industrial machinery used to bend and roll different types of sheet metal into a circular or conical shape. In the hydraulic industrial sector, plate bending machines are divided according to the rollers they have. So we will have three-roller machines ( 3 Rolls Plate Bending Machine ) and four-roller machines ( 4 Rolls Plate Bending Machine ).

For both types of machines there are different manufacturing models. In this case, so that you can choose the one that best suits your industrial needs, we will take care of analyzing the models of four-roller machines, that is, the 4 rolls plate bending machines .

4 rolls plate bending machines: RI72 from 1960Seravesi

In the field of 4-roller plate bending machines, the 4 Rolls Plate Bending Machine , also called RI72 of 1960Seravesi, is one of the most manageable and simple to use thanks to the possibility of comfortably accessing the hydraulic parts and the opportunity to always have it under control. state of efficiency of the machine with a quick glance at the control panel always within reach of the operator, so as not to encounter problems of any kind and have an excellent business digitization .

Perfect pre-curvature, speed and reliability, easy to use, precision positioning. These are the main characteristics of a 1960Seravesi RI72 characterized by solid metal carpentry and linear structures. But let's go into detail and take a closer look at the machine for a complete overview of its features.

The 1960Seravesi RI72 series roll benders are available with capacities from 25mm up to 300mm and roll lengths from 1000mm up to 6000mm. Roll positioning accuracy is guaranteed over time thanks to a linear guide system. The lower rollers are guided inside the machine structure, eliminating the possibility of play due to machine wear, unlike what happens on other machine models.

The pre-bending is carried out without using any lever system but following a minimal straight section thanks to the high force of the cylinders on the lower rollers. So we are talking about a perfect pre -bend also thanks to the elimination of the friction of the rollers guaranteed by a system of lubricated bronze guides. In addition, each roller of the 4 Rolls Plate Bending Machine uses two linear potentiometers that guarantee the parallelism of the rollers that are independently adjustable and tilt with comfort to allow the execution of the bending of the cone.

Plate bending machine: structure of the 1960Seravesi RI72

It deserves particular attention to describe the structure of the 4 Rolls Plate Bending Machine to give you an idea of how effective and technically perfect this 1960Seravesi model RI72 machine is .

The crosspieces, like the supporting frames of the rollers movement cylinders, are made of electro-welded steel and subjected to a 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. Furthermore, linear potentiometers are mounted on each roller of the 4 Rolls Plate Bending Machine to allow electronic control of the parallelism between the rollers.

The 1960Seravesi RI72 can have from two to six pumps for maximum linear and rotational thrust. A system with several pumps guarantees, in the event of a pump failure, an infallible operation of the machine even at reduced performance.

The cylinders of the 4 Rolls Plate Bending Machine 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. .

As you can see, it is a pleasure to analyze every detail of the 1960Seravesi RI72 because it allows us to understand what the right model is for your industrial works. We are talking about a machine with maximum efficiency able, thanks to a hydraulic opening handle , to allow the removal of the product tube in a horizontal position. In addition, the 4 Rolls Plate Bending Machine uses an automatic centralized lubrication system with a 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. The control also deserves a mention SIEMENS KTP1200 PN independent Touch Panel with 12 ”color touch screen display. Basically 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.

An extremely versatile machine that we invite you to discover more closely by asking for information directly to 1960Seravesi.
