What are the types of rolling machines?

With the rapid development of intelligent manufacturing and high-end equipment manufacturing, the intelligent level of sheet metal forming equipment is constantly improving. As one of the key processing equipment, plate rolling machine, is ushering in the double opportunity of technological upgrading and market expansion. Whether in the traditional manufacturing industry, or in the aerospace, shipbuilding, pressure vessels and other high-precision fields, the application of the coiler is increasingly diversified, and its performance is gradually to the direction of high precision, high efficiency and intelligent control.

What is a plate rolling machine?

Plate rolling machine, also known as metal rounding machine or plate bending machine, is a kind of machinery and equipment used to process metal plates and sheets into curved or cylindrical shapes. Plate rolling machine consists of a set of rolls, when the metal plate passes through, the rolls exert pressure on the metal plate, gradually changing the form of the metal plate, rolling it into the desired shape.

Plate rolling machine can be divided into the following three main categories according to the driving method and function: 

Currently on the market a wide range of plate rolling machine can be divided into the following three main categories according to the different driving methods and control precision: 

1. Mechanical plate rolling machine 

Mechanical plate rolling machine using gears, sprocket wheels, worm gears and other traditional mechanical structure to transfer power, the structure is relatively simple, the manufacturing cost is relatively low. This type of equipment is suitable for small and medium-sized metal processing enterprises, especially suitable for the product precision requirements are not high plain carbon steel plate coil production industry.
Advantages: low price, simple maintenance, easy to use; 
Disadvantages: lower adjustment accuracy, suitable for low precision requirements of plain carbon steel processing.

2. Hydraulic plate rolling machine 

Hydraulic plate rolling machine through the hydraulic system to control the movement of the rollers, can provide stronger pressure and more accurate positioning control, especially suitable for thick plate (20-60mm) and high-strength metal materials (such as stainless steel, titanium alloys, etc.) of the curved roll forming.
Main advantages: uniform pressure, flexible adjustment, high stability; 
Application areas: shipbuilding, energy equipment, military manufacturing and other occasions requiring high precision and strength.

3.CNC Plate Rolling Machine 

With the development of science and technology, CNC plate rolling machine has gradually become an important part of high-end manufacturing. This kind of equipment integrates advanced CNC system, supports three-dimensional modeling, automatic compensation, remote debugging and monitoring and other functions, which significantly improves processing accuracy and production efficiency.
Technical advantages: support one-key forming and intelligent identification in mass production to improve production consistency; 
Applicable industries: widely used in aerospace, rail transportation, wind power equipment, bridge manufacturing and other fields.

Distinguished according to the mechanical structure and the number of rolls: 

According to the number of rolls and the arrangement of different structures, the coiler can be subdivided into two categories: 

1. Three-Roll Plate Rolling Machines

There are a pair of side rolls and an upper roll in the three-roll plate rolling machine, in which the upper roll can move up and down.

Most three-roller plate rolling machine are equipped with three rollers and are more flexible in terms of output shape control than two-roller coilers. The most common types of equipment in this category are single-clamp and double-clamp structures.

2. Four-Roll Plate Rolling Machines

The four roller coiling machine makes the process of rounding steel plates easier and more convenient, but the structure is also more complex. It has a pair of side rollers, as well as an upper roller and a lower roller. The four-roll plate rolling machine not only accomplishes all the functions of the three-roll machine, but also creates square and rectangular workpieces in the rounding process. It is faster and more accurate in operation and does not have the problem of material slipping during the rounding process, but it is relatively expensive.
