640/5000 X-Press for machining


Gasparini-Industries-Compagnia-Siderurgica-640-5000-2

For Compagnia Siderurgica S.P.A., a leading company in the cutting, marketing and processing of sheet metal, we built a hydraulic press brake with Design Easy, a capacity of 640 tonnes and a worktable length of 5100 mm. The open-height is 950 mm, with a stroke of 600 mm.

 

This press brake is designed to be placed side by side with another 1000 ton / 7000 mm machine, which Compagnia Siderurgica already has at its disposal. In this way the two presses can work individually or in combination.

Tandem

This technological solution allows the press brakes to be used either individually or in tandem and thus be able to bend parts up to 12 metres long.

Crowning System

This press brake is equipped with Gasparini Adaptive Crowning system: to adapt in real time to the ram deformation, Gasparini relies on two precision sensors. The first one detects the ram bowing since the start of the bend. The CNC activates the cylinders in the lower ram until the reading of the second sensor is equal to the first one. The CNC drives the pistons in the lower crossbeam until the measurement of the second sensor is equal to that of the first. In this way, the two cross beams are perfectly parallel. The result is total control of the angle, with maximum precision and absolute repeatability, with all materials.

Safety System

The machine is equipped with the DSP laser safety system with PLC and Gasparini’s DSP-AP laser holders.

 

This allows the speed change point to be lowered by up to 4 mm from the sheet. The result is that the upper ram moves at high speed for longer, limiting the part of the bending sequence where speed is reduced to a minimum. The DSP-AP laser protection also supports auto blanking for automatic recognition of box and side wall profiles.

 

When the machines work in tandem, the front barrier is active.

Ram protection

To overcome the problem of parts of a certain size/size colliding with the upper ram, protective strips have been applied to the ram. In this way, longer metal sheets or special boxes do not collide directly with it and the machine remains protected from scratches and other resulting damage.

Clamping system

The upper clamping system is hydraulic self-aligning type H-GG for punches or intermediates (hardened plate on upper ram).

 

The lower clamping system is also hydraulic.

Backgauge

The backgauge has 4 axes (X-R-Z1-Z2) controlled by CNC, and an additional reference has been added.

CNC on mobile pulpit

The CNC is the Delem DA-66T, equipped with DM10x modules (for uniformity with the existing machine), and is mounted on a mobile pulpit. The offline software is Delem Profile Lite TL 2D.

 

Foot pedals

The machine has two standard foot pedals.

Other systems and accessories

Compagnia Siderurgica has chosen to set up the press brake for Tele-Link remote assistance and install the Industry 4.0 package.

 

In addition, this press brake features:

  • Stand-by energy-saving system
  • 2 standard front supports
  • LED lighting of the working area
  • Electrical and CNC cabinet on the left side
