Coil-punching line ALPI DECA

Coil-punching line ALPI DECA

The coil-fed cutting/punching lines of DECA series reach high-productivity performances and extreme usage flexibility. The interpolation of the machine movements – sheet advance, transversal motion of the tools units, units continuous rotation of 360° – and the detection of hammer position allow to cut any shapes or geometrical shapes from coils of any metal materials (i.e., iron, stainless steel, copper, aluminium, etc.) and non-metal materials (i.e., PVC, nylon, teflon, etc.). Also, it is possible to make holes, oblongs and notches – with small or big dimensions – by means of punches or nibbling operations. The punching machine can be equipped with up to 20 tools, in station A, B and C, with fast automatic change (less than one second) controlled by the machine CNC. The tools hammer is activated by a reliable latest-generation mechatronic system reaching high positioning precision through a low electric power supply. This system allows ALPI DECA to convey to the punches only the necessary force for cutting materials (maximum force: 10 tons), thus saving a lot of energy and setting tools within few hundredths of a millimitre. Three couples of rubber-coated rollers are overlapped and motorised, in order to push sheet with a fast advance and without restarts; furthermore, they allow processed-parts automatic unload. Specific forming tools allow to mark processed parts, deep draw, make ribs and small borders, make references for folds. All working processes – also the cutting ones – are carried out with mechanical tools avoiding any fumes and incandescent slags; so, the cutting procedure does not damage the material surface or any protective film. The coil-fed cutting/punching lines can substitute traditional punching lines, cutting lines and plasma-cutting lines, without previously cutting sheets, loading and unloading them from the working area. The lines run without interruptions and without any operator’s interventions, because several programs can be uploaded, the line is coil-fed and processed parts are automatically unloaded. The usage of linear and torque motors brings high speed, positioning precision, absence of transmissions or wear, and reduced maintenance: all these factors are fundamental for a perfect punch/die match.

ALPI DECA lines can be supplied according to three different versions:

  • DECA N: machine equipped with a manual opening on the tool holder; it is really suitable for customers that don’t need to change the multitool configuration frequently.
  • DECA A1: Motorized multitool opening; this is a good solution for customers that often substitute the tools in the tool holder.
  • DECA A2: Double motorized multitool; this is the perfect solution for customers using a large tools number. All the tools are indexed and completely managed by the CNC.
