WORKING UNITS

1. Working units base

· This base can hold the two punching units, the shear and the marking unit.

2. Marking unit with 4 marking groups

· Hydraulic marking unit having the following main technical features:

3. Punching units

· Two hydraulic punching units: 1 unit to punch the angle bar right-hand flange, and 1 unit to punch the angle bar left-hand flange.

· Each punching unit is fitted with three (3) special removable punching tools and each of them is positioned thanks to ball screws and servomotor on an infinite number of gauge lines selected by the CNC.

· Each punching unit is fitted with a hydraulic multiple hold-downs system to clamp the angle bar thus ensuring the punch extraction.

· Main specifications of each tool:

Each punching unit is fitted with nr. 3 punches and nr. 3 dies for the maximum round hole diameter.

4. Shearing unit

· The shearing unit is made of one hydraulic Double-CUT shear for angles complete with hold-down.

· Shearing capacity Max. available shearing Force 750KN

OUTFEED CONVEYOR

Idle rolls outfeed table for 6 mt long bars (one-side tiltable)
