TECHNICAL FEATURES


FRAME
Project and verification of main elements with FEM system.
High strength normalized welded steel construction.

MOTOR
The main motor with variable speed on each model.

DRIVE
Simple or double gear reduction.
Fast shaft with spiral milling cutter made from the shaft itself.
Gear reduction in oil bath.
The eccentric shaft, made in chrome-molibdenum steel, has the following options:

  • Eccentric shaft fixed stroke length;
  • Eccentric shaft variable stroke length, semi automatic or automatic;
  • C-link with slow down speed of slide to the B.D.C;

SLIDE
Made in cast iron , adjustment of die space with brake-motor and mechanical display with decimal resolution 0,1mm.
Guiding system with 8 bronze gibs to get a perfect allignement of slide in each point of stroke length.
Low pressure adjustable cylinders to balance slide weigt and clearances of parts working in alternate motion.

HYDRAULIC OVERLOAD SAFETY
All models are equipped with hydraulic overload safety.

LUBRICATION PLANT
Composed by gear oil pump and progressive oil distribution unit.
The plant is monitorized with oil level alarm and pressure oil alarm.
The plant is also studied with total recovery of lubricant.
