The coil punching machines of ALPI model are innovative, flexible and have high productivity rates.
The coil punching machine ALPI presents three series, all with different tonnage, for better satisfying the needs of the different productive sectors: ALPI ESA, DECA and VENTI.
The coil-fed punching machine ALPI ESA (power: 5 tons) is the ideal line for sectors like insulation, thinsmithery and ducts production.
The coil-fed punching machine ALPI DECA (power: 10 tons) can be equipped with up to 8 tools in stations A, B and C, running with fast automatic change (less than one second) controlled by the machine CNC.
The coil-fed punching machine ALPI VENTI (power: 20 tons) is the top-of-the-range product of Produtech punching technology: thanks to high power, up to 10 tools in stations A, B, C and D can be installed, for high productivity and extreme usage flexibility.
Through the interpolation of all the machine movements (i.e. sheet advancement, transversal motion of the working units, tools holder rotation and control over hammer position), any shapes or geometric figures can be cut out of coil, both in case of metal materials (carbon steel, stainless steel, copper and aluminium) and other materials (PVC, nylon, teflon). There are no limits in the production of holes, slots and notches, which are carried out by means of one tool in case of processes with reduced dimensions, or nibbling in case of processes with large dimensions.
Also, the processed parts can be marked with logos, and it is possible to make deep-drawing, air vents, ribs (even curvilinear, by means of suitable wheel-tools), small beads and references for folds. All the processes - including cutting - are made with mechanical tools that do not produce fumes or incandescent scraps, so they do not affect superficial finishing or any potential protective films on the processed materials.
All tools rotate and are operated by a hammer. The hammer is run by a reliable latest-generation mechatronic system providing high positioning precision with reduced electric power: thanks to this device, ALPI confers to the punches only the necessary strength for cutting the material, with high energy savings and accuracy (few hundredths of a millimeter) while positioning tools.
Last, linear and torque motors assure high speed, positioning precision and absence of backlashes and wear, as well as minimum maintenance: all these factors are fundamental in order to keep perfect punch&die match.
