Automation of sheet lines

Distributed to Spain by representations techniques Corominas, S.L, specialised in machines for deformation, assembling and automatic mounting, Cisam Impianti engineering focuses on the development of the sheet. The Italian firm specializing in the automation of the work in steel processes, integrates different lines of production, standard modules and flexible and modular fully automatic lines developed based on the specifications of the sector.

The compact power lines were planned, in order to feed presses and/or shears, occupying spaces reduced with respect to the facilities. The main feature of these machines is the compact concept. The configuration type, composed by Unwinder, console's introduction, enderezador/feeder, occupies a space of only 4 m. The desenrolladores can be fixed or mobile, with or without a trolley load of coil, and offer the possibility of selecting the type of de-coiling which is determined according to the typology of the material to develop. It can be tricky, very thick or rather high resistance.

Enderezadores/feeders are manufactured in five different models. A range that offers the possibility of working bands with thicknesses ranging from 0.5 mm to 14 mm, width of 300 mm to 2000 mm and weight of coils of 3000 kg up to 30000 kg.

Guaranteed food accuracy is ± 0.1 mm, may not be combined with gear motor and small game brushless. All lines are supplied with a special system of CNC hydraulic piloting of 99 programs.

Compact lines are especially suitable to be mounted on a movable structure on Rails to feed more than a press, or insert a charger of formats for a transfer system. Available numerous optional elements, are to ask for order. All lines can provide with regulations manual, motorized or programs and can be accompanied by shears, lubrificadores band, food group to transfer systems and security fences.

Long food lines are especially suited to work materials sensitive and pretreated, such as stainless steel, aluminum, prebarnizados and pretratados. During the development of delicate or pretreated material, it is not possible to stop the band in the enderezador, it could damage (mark) superficially leaving shadows.

Its configuration achieves higher speeds work, mainly working with long progress. Its standard range provides a range of facilities capable of working with bands whose thickness is 0.5 mm to 10 mm, width of 300 to 2000 mm and weight of the coil of 3000 kg to 30000 kg.

The enderezadoras integrated in these lines is equipped with 7-9-11-17-21 rollers that can be covered by block, or rather is sectioned with simple or double system of roller and on request with the removable full block.

The provision of traction rollers are all motorized while straightening roller can be motorized or only those in the lower block.

The control of the loop, via solar cells or sonar, is done with the system on/off, or by autoregulable Dynamics depending on the speed of the press and the rate of progress.

This series of machines, called Saet, has been made in order to automate the process of welding line of die-cutting, profiling, lamination and rolled, cut longitudinal and winded, allowing work continuously either form coils of large formatby welding with TIG procedure the head and tail of the band, quickly and without manipulation by the operator. In order to reduce the time in the change of bobbins operation Cisam Impianti has made a special desenrolladores that allow the operator to prepare this coil outside a by area of work, liberating it from strapping or other fixationswith the end of list head to be introduced and positioned automatically to the junction of welding. This system is advised mainly where there is the need to feed rotating warehouses of accumulation, or when it is necessary to change reels often.

Obtained welds prevents the breakdown of the band during successive processing operations.

This machine is manufactured in several models: Series C, used for welding of bands whose maximum width is 400 mm and 0.2 to 3 mm thick, and that the band be drawn laterally after welding; the L series, used for welding of bands whose maximum width is 1000 mm and 0.4 to 3 mm thick and the P series, used Parthian welding of bands with maximum width of 2000 mmm and thickness from 0.6 to 10 mm.

The compact automatic welding, straightening and feeding lines have been studied especially for stamping with the use of progressive step dies, with delicate and expensive equipment that allows to work continuously with large format rolls, welding head and tail quickly and without manipulation by the operator.

They are equipped with a high precision mechanics that cut and perfectly positioned the edges to be welded forming an entre-hierro between the head and the tail of the variable band depending on the thickness, facilitating the penetration and leaving a slight collapse for a welding of high-quality without overlap and without highlights of material to remove.

The possibility of carrying out welding without losing the band's position in a progressive die are also planned. This series is manufactured in various models.

The line for magnetic sheet has been projected for bands of little thick magnetic sheet feeding, to minimize downtime of change of coil and obtain an optimal flatness of the band feeding them at high speed (80 m/min).

The series is equipped with Unwinder cantilever, carriage of cargo, pinch - roll (roll of introduction) that have the function of preparing the roll out of line, guaranteeing a stoppage of the installation by change of coil of 20 seconds approximately.

The welder (optional), allows the Union of the head and tail of the coils quickly and without overlap.

On the line for fixed Court Cisam Impianti has designed and conducted a series of specific facilities for the preparation of bands of very thick to thin cutting presses, manufactured in three models. One of the ranges offers the possibility of developing bands with thickness of 2 mm to 14 mm width of 50 mm to 600 mm and weight of coils up to 10000 kg. The modularity of this line allows to configure it with various combinations from the simplest.

This type of feeders are especially suitable to feed transfer presses which require very high performance, ensuring the maximum precision of both axes.

Multiple feeding CN systems operating in zig-zag, equipped with advanced electronics and a special system of optimization of the parameters, enable an economic use of the bands, entering the corresponding keyboard programming, data relating to the diameter of the workpiece to producethe width and the thickness of the band.

They can provide in two versions: configuration long, suitable for the work of bands of stainless steel and pre-barnizadas plates, and compact, perfect for working with bands that are not particularly sensitive and when it is needed to reduce the working area. Both can be complemented by numerous stacked devices, locking jaws, transfer and support of the cut pieces. Its range of production covers lines of court for bands of width between 300 to 2000, thickness from 0,5 up to 10 m and weight of coils of 3000 to 30000 kg.

Also available lines of e-management for the winding of steel and non-ferrous metals, are provided with a change of bobbins in auto, welding of head and tail of band rebordeando with rollers or tools and winding reels or disposable cardboard.
