Description
Technical Field
The utility model relates to a cable manufacture equipment technical field specifically is a sheath for producing combination fire resisting cable extrudes and uses aircraft nose.
Background
Common fire-resistant cables in the current market are mainly applied to elevators, subway power supply systems and public place building floors requiring higher fire-resistant grades. The mica tape is mainly used for wrapping, so that the integrity of a line can be realized under the condition of a fire disaster, and the normal operation of equipment is kept. However, in the prior art, a layer of mica tape is wrapped outside the conductor, and the structure with the fireproof effect has the defects that the mica tape has no coverage rate and is wrapped in gaps due to unstable tension during wrapping, and the phenomena of easy curling, breakage, falling of the mica layer and the like of the tape occur in the wrapping process.
Therefore, a novel combined fire-resistant cable appears in the market, and the production steps mainly comprise extruding a ceramic silicon rubber material on a conductor by an extruder to form a fire-resistant layer with the thickness of 0.5 mm; extruding an insulating material with a specified thickness on the fire-resistant layer through an insulating extruder; stranding the insulated wire cores into cables by a cable former, and injecting inorganic silicate fire-resistant glue into gaps of the cable cores; extruding the sheath material with a specified thickness through a sheath extruder.
An extruder is an essential device in the production of the new composite fire-resistant cable, which allows the melt to form a continuous, dense tubular coating around the core. The head of the cable extruder consists of an alloy steel inner sleeve and a carbon steel outer sleeve, and a forming die is arranged in the head. The machine head is used for converting the melt of the material to be extruded in rotary motion into parallel linear motion, uniformly and stably guiding the melt into the die sleeve and endowing the material to be extruded with necessary forming pressure.
The forming die arranged in the head of the extruder comprises an extrusion tube type die, a semi-extrusion type die and an extrusion type die.
Wherein, crowded tubular mould: the mould core is provided with a long nozzle, and the nozzle of the mould core is generally kept flat with the opening of the mould sleeve when being matched, so that the extrusion pipe type mould is formed. Compared with an extrusion type die, the drawability of the material to be extruded is utilized, and the extrusion type die has the advantages of high efficiency, easy deviation adjustment, good bending property of the extruded wire core, long service life, strong die matching interchangeability and the like, but is inferior to the extrusion type die in the aspects of extrusion compactness, extrusion quality and the like.
Semi-extruding a tubular mold: also known as a semi-extrusion die, the die core has a "short mouth", typically the die core die mouth is at 1/2 of the sizing area of the die sleeve. The semi-extrusion pipe type die is the same as the extrusion pipe type die in general, but the length of a die nozzle is shorter than that of the extrusion pipe type die, and the length of a sizing area of a die sleeve is slightly shorter than that of the extrusion pipe type die, so that the advantages of the extrusion pipe type die and the extrusion type die are absorbed, the applicability is wider, and the die is suitable for extrusion when the flexibility of a wire core is better or the wire core is straighter.
Extruding die: the die core and the inner side of the sizing area of the die sleeve are at a certain distance, the final sizing of the product is realized by using pressure, and the material to be extruded is directly extruded and wrapped on the wire core or the cable core through extrusion, so that the extrusion is compact and firm, and the surface is smooth and flat. But the core is easy to be eccentric, the service life is not long, the requirement on die matching is higher, and the bending performance of the extruded wire core is not good. The extrusion die is suitable for extruding small-size wire cores; the wire cores are compact in extrusion requirement, round and uniform in appearance requirement; and the material to be extruded has a smaller stretch ratio, and the like. Therefore, the extruding pipe type die, the semi-extruding pipe type die and the extruding die have the advantages and are suitable for different working conditions.
In the production of composite fire-resistant cables, different extruders are required in different steps to achieve the best product quality, and therefore, it is necessary to develop a machine head for an extruder that can be adjusted.
