Overhung decoiler

Device for uncoiling the metal sheets and their further feed into the rolling mill. Equipped with automatic control system.

Overhung decoiler

Technical specifications

Installed power, kW 7,5 (11)
Dimensions (L x B x H), mm 2 480 x 1 730 x 1 830
Load capacity, kg до 10 000
Roll width, mm 1 250
Internal roll diameter, mm от 480 до 620
Full diameter, mm 1 500
Thickness of rolled metal sheets, mm 0,3...2,0

Benefits of the decoiler

  • Possibility of operation as part of high-speed lines (7.5 kW is enough to quickly uncoil a heavy roll).
  • Extended service life; , designed for a load-carrying ability of 10 tonnes without a supporting frame.
  • Allows to uncoil rolls with internal diameter of 500 mm (made in PRC).
  • Does not damage the inner surface of the roll (in contrast to the double-beat decoiler).
  • Thrust bearings do not wear out.
  • Equipped with an automatic control system, which allows to monitor the slack, the speed and direction of movement

Additional options

The decoiler may be equipped with a mobile charging and lifting trolley. The trolley is required for unloading the crane equipment, which is constantly involved in the offloading of profiles and the engaging of new rolls.

The decoiler may be equipped with hydraulic unclamping device (for fast engaging of rolls) Roll decoilers (types and characteristics)

Cutting machine for quick roll change

Cuts the last sheet from the mill in order to quickly change the roll to another color.

Cutting machine for quick roll change

Before engaging another roll for the next order, it is necessary to wait until the sheet fully rolls out from the mill into the previous order (no waste).

To do this, the line halts the rolling mill in place where the last sheet must be cut. Cutting is carried out with the help of a cutting machine.

The shears can be equipped with a manual or electromechanical drive.

3

Sheet lamination unit

A device for fixing a roll of film for the lamination of smooth sheet before profiling.

Sheet lamination unit

Laminated profiles do not get scratched during transportation and installation; the protective film is removed after the installation so the surface is free of scratches and false images.

4

Profiling rolling mill

A profiling rolling mill performs its main function, i.e. it turns a smooth sheet into a corrugated steel sheet.

Rolling mill is a sheet metal processing machine that uses pressure between the rotating rollers to obtain the desired profile. The mill is a set of rolling stands with an electric drive mounted on a frame.

The geometric accuracy, the quality of production and mill service life depend on the tool manufacturing quality, selected rolling scheme, the number of working stands, the design features of the rolling mill, the power, and the drive design.

Profiling rolling mill

Benefits of the rolling mill

  • Rolling sped up to 50 m/min. We made a number of significant improvements in our rolling mill in order to achieve this speed, provided there is rapid acceleration, deceleration and the ideal profile quality.
  • Solidary roll forming scheme. This means that all the stands are full-crest (as opposed to wedge rolling when the middle part is formed first, and then the profile edges are formed). Solidary roll forming scheme allows to improve the profile quality (no herringbone along the edges of the profile as opposed to V-type rolling) and reduce the size of the rolling mill.
  • Fixing rollers and shafts via a keysteel, there is a key slot on the shaft and the roller (as opposed to wedge mounting where the roller is attached to the shaft with a screw).
  • Minimum shaft diameter — 100 mm. This ensures that the rollers will not deflect in the middle during the sheet profiling (0.10 mm deflection is enough to make the center of the profiled sheet look unrolled).
  • Manufacture of tools using the high-precision machining centers in the US – the high precision for thin metal profiling
  • There are no herringbone along the edges, no rerolls and false images
  • A tool with increased load undergoes obligatory heat treatment
  • The working tool is made of St40H steel. The working tool service (with heavy use of the mill in 3 shifts) – at least 10 years.
  • Our mills may be used for metal with different properties (we do not tie to a specific supplier). Our equipment is manufactured for a predetermined thickness range (for example, the quality profiling of sheets with a corrugation height of 60 mm and a thickness of 0.7-0.9 mm requires a mill with 20 work stands, and the same sheet with a thickness of 0.5-0.9 mm requires 23 stands). However, the profiling quality of metal produced by different manufacturers remains the highest.
  • The tool is equipped with levering feet for installation on an uneven surface.

Дополнительные опции

In order to form “Dome-type” shaped contours, there is a machine with manual feeding of the profiled sheet. The metal sheets rolled and decorated with the help of our machine are widely used in the construction of corrugated board fences with shaped contours. Custom contour shape (depends on the corrugated board geometry).

The equipment consists of a feeding table and electromechanical 3D-shears. Contour cutting is produced in a single pass.

The machine is supplied on the customer’s request in addition to the profiling line. Cost — 9573 EUR.
