Cage assemblers and cage making machines

Cage assemblers and cage making machines
Machines which carry out the electrowelded assembly of cages and ringed piles. The construction phase i.e. the welding of the elements, may be done manually or, depending on the machine model, by means of automatic and programmable robots.

PRATICA 240
Plant for the assembly of reinforcement steel cages. Because of its patented system, the plant can be used to assemble cages of varying shape and size. It eases the positioning of all the elements (stirrups, bars and bent bars) which make up the reinforcement cage, before the welding or tying phase, depending on the method adopted.

-Maximum dimensions of the cage: 2400 x 1000 x 1400mm.
-Minimum dimensions of the cage: 140x140mm (100x140mm).
-Closed stirrups wire diameter sizes: from 4 to 16mm.
-Longitudinal bar and/or bent bar wire diameter sizes: from 4 to 40 mm.

PREFORM C
Electronically programmable machine for the automatic production of iron cages to be used in reinforced concrete. It is possible to assemble pre-cages having a great variety of shapes and dimensions, automatically welding the stirrups to two or three longitudinal support wires. Allows the use of different diameter stirrups within the same pre-cage assembly, separated by constant or variable distances/steps, which guarantees the maximum flexibility and quality according to the specific production requirements.

Diameters of closed stirrups: from 4 to 16mm. Diameters of longitudinal support wires: from 4 to 8mm.
Maximum dimensions of the cage/pre-cage: 1000x1000x8000mm (other dimensions on request with consequent price difference). Minimum dimensions of the cage: 150x150mm.

GAM 1500
The plant automatically produces cylindrical cages (ringed poles) by means of a procedure which is based on the formation of a wire spiral which is wound around a series of longitudinal bars, positioned in a circular order and supported in the horizontal plane by a special fixed head and other mobile heads which can translate along guides. The spiral formation system is fed from coil on an adjacent payoff wire-unwinding unit. The spiral pitch is programmable and its attachment to the longitudinal bars is attained by continuous wire welding. This is carried out manually or completely automatically by a special welding robot.

- Plant dimensions extremely contained, in proportion to the maximum dimensions of the cages which may be produced, hence allowing correct optimization of the area destined for production.

- Lateral unit for longitudinal bar storage located adjacent to the loading point, with benefits in terms of:
- reduction in machine size;
- reduction in bar loading and positioning times;
- reduction in operator fatigue.
- Hydraulically powered vices for bar blocking with consequent diminution in preparation time.

- Independent dyes for bar support which allow:
- selection of the number of bars to be used (even or odd) and their positioning at the right distances from each other;
- attainment of optimal welds resulting from the absolute mechanical stability in so far as there is a contrast base between the bars and the spiral;
- optimization of machine preparation for successive jobs, which can take place even with production in progress.
- Highly efficient and flexible automatic welding robot (external cage diameters from 100 mm to 1500 mm).
- The longitudinal translation of the support heads provides only the rotational movement of the cage; the fact that this latter does not translate determines the significant containment of the plant dimensions.
- Great simplicity of system management by means of a dedicated PLC.
