Punching machines from coil


Automated punching process from a coil

DECA is a CNC machine specially designed for cutting, punching and stamping sheet directly from coils. The DECA rotation head can hold up to 20 tools. The CNC rotation the head allows an automatic and very fast change of the working tool, less than a second. Each of the ten tools has the possibility to rotate of 360°, the rotation is CNC controlled. The vertical run of the hammer of the hydraulic head is CNC controlled. The interpolation of the machine movements, such as the CNC controlled longitudinal strip movement, the CNC controlled transversal head movement, the CNC controlled 360° head rotation and the run of the vertical run of the hammer position allows the execution of any shape or geometrical figure. The ALPI -DECA machine can process every metal as for example carbon steel, stainless steel, pre-painted steel, copper and aluminium.

HYDRAULIc PLATFORM

Lift table tandem scissor for evenly distributed load to put between the cutting –punching machine and the feeding-straightening unit to make easier introduction of the sheet into the cutting –punching machine.

CAPACITY:                             1000 kg
HEIGHT:                                   800 mm
PLATFORM DIMENTIONS:  2500 x 1000 mm
MOTOR:                                   380V – 50 Hz, 0,75 kW
WEIGHT:                                  360 kg



feeding and straightening unit


The feeding and straightening unit mod. P.UR is a heavy-duty straightening unit. The structure is designed and built using high thickness electro-welded steel sheets, annealed and machined with high- precision automatic CNC machine-tools.







COIL HEAD FEEDING AND GUIDING GROUP


MAX. WIDTH    
                                1500 mm
RECOMMENDED THICKNESS:  from 1,5 mm
DRIVE:                                               Hydraulic pistons

The unit consists of two parts, one guiding the strip from the decoiler to the feeding and straightening unit and the second guiding the strip from the straightening to the cutting/punching machine. The unit is made of mobile supporting tables and coil pressing rolls. The strip supporting tables come into position in automatic by means of hydraulic cylinders when starting a new coil and go back to a stand-by position during the machines working cycle. The coil pressing rolls allow an easy passage of the head of the coil through the line.


motorized LOADING COIL CAR SYSTEM


COIL WIDTH:
                        1500 mm
OUTER COIL DIAMETER: 1200 mm
CAPACITY:                           10.000 Kg
VERTICAL STROKE:          200 mm
HORIZONTAL STROKE:    1300 mm
DRIVE:                                    HYDRAULIC PISTONS
DIMENSIONS:                       1000 x 1200 x h 600 mm
WEIGHT:                                 1000 KG

The structure is designed and built using high thickness electro-welded steel sheets, annealed and machined with-precision automatic CNC machine tools. A hydraulic system allows the vertical movement of the coil car and lifts the coil to the programmed height. When the hole of the coil is in line with the mandrel of the decoiler the coil car moves horizontally until when the mandrel is completely inside the coil hole. The coil
car goes then back to the stand-by position ready to be loaded with a new coil.


HYDRAULIC SHEAR

Assembled in front of the cutting-punching machine can cut carbon steel with a max thickness of 4mm.
