CNC SHEET BENDING PRESSES

CNC sheet bending presses provide cutting edge bending technologies. Sheet bending presses manufactured by the open joint-stock company “KUZLITMASH” meet highest standards for equipment used for sheet material products. They allow manufacturing the widest range of metal sheet products.
Designed features of presses.
  • body of the press is a welded annealed structure, with minimal deformation under load;
  • drive of the bending ram is powered by two hydraulic cylinders and hydraulic system, made of component parts supplied by the “Rexroth” company;
  • there are three speed options for a bending cycle, which ensure fast feed for punch stamp, optimal bending speed and fast return of the ram to the initial position;
  • control over synchronous running of rod stokes of hydraulic cylinders is provided by two optical-electronic rules fixed along the ram sides, by CNC system and proportional hydraulics;
  • Y1 and Y2 axis motion is executed with positioning accuracy ± 0.01mm. This ensures the accuracy of angle bending irrespective of work position in the working area. (NC-operated back stop motions: X axis horizontal (forward-backward), R axis vertical (up - down), Z1 and Z2 horizontal (left-right) with positioning accuracy ± 0.1mm).

Delem DA-66T CNC system

The press is equipped with the Delem DA-66T CNC system, which guarantees high reliability, efficiency and ease of operation and is one of high performance control systems used in sheet bending presses. Its real time operation is based on Windows R.
Electronics, meeting the state of the art technical requirements and widespread modular hardware, provide additional advantages;

  • support of user friendly  applications (standard Windows programmability); access to this function during technological process is secured thanks to  multitask control system software shell;
  • large memory;
  • keyboard and mouse interface (USB);
  • sensor interface for bending and correction to meet highest requirements for sheet bending presses;
  • 2-dimensional modeling

Standard equipment supplied with the press:

  • bending tools: sectional punch and sectional die with impressions 16, 22, 35 and 50 mm wide (for molders having up to 1600 kNinclusive);
  • tool clamping according to European standard (such as PROMECAM-AMADA) with mechanical lock;
  • remote control panel;
  • foot pedal;
  • two adjustable supports in front;
  • photoelectric protection of working space on the press brake rear;
  • pendant;
  • side guards
  • тwo safety blocks.

Standard equipment depending on configuration:

- table deflection off-set mechanism (bombardment mechanism) – NC manual or automatic
- back stop with programmable number of axes: 1(Х); 2(X;R); 4(X;R;Z1;Z2); 5(X1;X2;R;Z1;Z2); 6(X1;X2;R1;R2;Z1;Z2).

Options available at additional charge:

  • вending tools for pressing machines with more than 1600 kN
  • special tool
  • quick and easy tool change
  • laser-based protection of working space
  • NC Delem DA-69Т– 3D modeling
  • еquipmentforsheetmaintenance
