Metal Corrugating Machine

Metal Corrugating Machine

In the building industry, metal corrugated sheet steel is a popular construction material for walls and roofs.metal corrugating machine The wavy pattern of this type of steel creates a very strong material that is resistant to most impacts and weight loads. It is also an economical choice for roofing applications. Corrugated steel sheets can be made in a variety of colors and finishes to add beauty and style. In addition to its aesthetic value, this type of steel is highly resistant to corrosion and offers high strength-to-weight ratio. This makes it a great option for many different building applications.

The present invention relates to a machine for longitudinal corrugating of sheet materials, particularly of metal with stepwise folding/bending over free-running rollers and counter-rollers, so that alternating longitudinal convex and concave corrugations are formed.metal corrugating machine The profile heights and widths can be freely regulated with the use of simple standard equipment.

Existing roll-forming mills are based on a fixed setting for the profile and corrugation patterns, therefore they offer only a limited choice of profiles.metal corrugating machine Moreover, they are very time-consuming when changing from one profile to another. The invention can be characterized by the fact that the profile forming rollers are not located on juxtaposed pairs, but are arranged in a group of pairs in each forming step. In addition, there are preferably also movable special units for various means of shaping the profile edges, in particular the chamfered ones.

When a sheet of metal is fed into the machine it runs over the first forming roller unit with a smaller drive diameter than the other one. This causes a gap to be obtained between the sheet running in front and the subsequent sheet, which is caught by the main drive rollers. In this way the sheet can be guided to a receiving table without interruption and without risk of the corrugating process being interrupted, since the elastic feed-rollers are able to yield and slip with modest roller pressure.

In the preferred mode of construction the forming rollers are all located on an upper and an equivalent lower shaft. In this way a large number of different profile shapes can be produced.

The forming rollers are arranged in pairs and are not connected to each other, but the two forming rollers of each pair are positioned alternatively on the upper and the lower shaft. This ensures that a gap is always obtained between the sheets. At the same time it is possible to change from one profile to another by simply replacing a single set of forming rollers with a new set of laterally pre-adjusted ones.

This mode of construction eliminates the need to replace all of the forming rollers with new ones when switching from one profile to another. It is therefore considerably easier to reset from one profile to the next and it is also quicker. In addition, the length inaccuracy of the forming rollers can be reduced substantially. This is a very important advantage over known machines.
