A
PURPOSE
Automatic line for production of grid VM2012 is intended for production of netting by electro-resistant welding, with following characteristics:
Diameter of chord:: Ø4 – Ø10
Distance of chord:
- longitudinal 100, 150 and 200
- cross-section 100, 150 and 200
Dimensions of grid:
- length 6000
- width 2150
B
Mechanical system
Mechanical system is made of the following mechanical assemblies:
1) Storage of longitudinal chord:
For accommodation of longitudinal chord cut on 6000 mm
2) Auxiliary arm:
Auxiliary arm enables transfer of longitudinal chord from the storage to the main arm.
3) Main arm:
Accepts longitudinal chord from auxiliary arm and puts it into the tool for electro-resistant welding of the press with preset stepping.
4) Press with the tools for electro-resistant welding:
On positioned longitudinal chords into the tool, and brought cross-section chord from the dispenser, press makes pressure with upper electrodes to formed nodes via pneumatic cylinders. By means of current through the booster, electro-resistant welding is done.
5) Dispenser of longitudinal chord:
Dispenser is consisted of storage of cross-section chord with drive mechanism for bringing out of chord from the storage and mechanism for dosing of cross-section chord into the press for electro-resistant welding.
6) Ejector:
It ejects netted chord from the press to the unloading mechanism for reception of finished chord.
7) Unloading mechanism:
Receives finished chord and packs it into transport trolley to the storage of finished chord.
C
Energy-controlled system
Energy-controlled system is made of the following assemblies:
8) Energetic mechanism:
Transformers with installed electro-motors on the line.
9) Controlling mechanism:
Controlling mechanism consolidates automatic activity of entire line with the possibility of programming by the dimension of grid and velocity of movement of mechanical and cinematic mechanisms of the line.
