Cassettes for compacting heads

The basic condition that must be met is that the pairs of rollers are in the smallest distance which is possible. This requirement is particularly important when, system pairs of rollers, compacted conductor of round shape.

Another important requirement is that the carriers of rollers (jaws), always hold the rollers completely centric  one to the another. Of course, it is necessary and must be a absolute parallelism of the sides of the rollers and that this situation can not distort during tightening at the desired distance and regardless of the pressure force which can be realized.

Jaws of rollers are designed so that the bearings are an integral part of the carrier of roller. In this way is a greater body of roller and with the possibility that may be submitted by high pressures during the compaction of large cross-section.

 BASIC TECHNICAL CHARACTERISTICS OF ROLLER CASSETTES FOR COMPACTING HEADS

 

The construction of the cassettes is based upon many years of practical work with world class manufacturers of various types of cassettes on the vide range machinery for stranding and compaction the conductors for power cables.

 

1. The basic condition that must be met is that the pairs of rollers are in the smallest possible distance. This requirement is particularly important when, system pairs of rollers, compact conductor of round shape.

2. Another important requirement is that the carriers of rollers (jaws), always hold the rollers completely centric one to the other. Of course, it is necessary and there must be an absolute parallelism of the sides of the rollers and this situation can not be distort during tightening at the desired distance  regardless the pressure force which can be realized.

3. Dimensions of rollers are designed to the optimal diameter and width so that compaction of all dimensions of conductor’s cross-sections from 50 to 1000 mm2 round shape and all cross-sections to form segments for cross sections up to 3500 mm2 can be successfully performed.

4. Carriers of rollers are designed so that the assembly and disassembly of the rolls is done easily and without special efforts. Installation and removal does not require any special setting of centricity. It is sufficient that bearings are properly tighten after setting. The special seat washers are sufficient to provide the centric position of the rollers in relation to the carrier of rollers and a cassette without any adjusting and special setting.

5. There has been a complete protection against loosening of assembled elements on carrier of roller while working on the stranding machine.

6. Adjusting the centricity of neighboring pairs of the rolls is carried out easily because they are still visible to the position of each roll in relation to the center line of the machine. A millimeter division on each cassette is built so that the operator can clearly see the position of each pair of rollers relative to the center line at any moment.

7. Set of assembled cassettes is designed so that the connection of cassettes is simple and easy to connection between the coupling element and the carrier on the stranding block, which can be different and depends on the structure and type of stranding block. In this way application of cassettes on almost all types of machines for stranding can be easily performed and receives the possibility that the same type of rollers can be used in producing all types of machines for stranding in compaction process. This facilitates the planning of tasks and facilitates the operational work in the production plant.

8. Each Compaction head (set of assembled cassettes) has the die carrier to set of dies with 80 mm outer diameter.

9. Installation and relocation of rollers with bracket is quick and easy. A time line setting for the operational work is shortened several times in relation to the operation with the cassettes type “Cortinovis” and the similar ones.

10. The operator of the machine should be adjusted centric pair of rollers in relation to a designated position on the cassette and to make tightening on the necessary distance. Simplifying of handling is given an opportunity to relatively poorly trained operators to successfully set up the machine for a good quality production.
