Description
Technical field
The present invention relates to a kind of cable or heating tape Product processing equipment technical field, particularly a kind of accompanying-heat cable crosslinking
Polyolefin insulation layer extrudes technique.
Background technology
The processing technology of the product such as cable or heating tape mainly includes drawing, process and cladding：Drawing is mainly used in processing
The conductor wire core of cable or heating tape, makes metal bar by pulling force effect or thicker metal wire is forced through mould, metal bar
Or the sectional area of metal wire is compressed and obtains required section shape and size；Process is to improve cable or heating tape
The pliability of core, entirety degree, and the Kelvin effect for overcoming single cable or heating tape core to exist, and many single lines are pressed
According to predetermined direction weave in；Cladding be primarily referred to as the product such as cable or heating tape one layer of conductor thread core outer wrapping or
Multi-layer insulation and jacket material, thermoplastic superior performance, with good process industrial art performance, in particular for electricity
Technique is easy when cable or heating tape extrude insulating barrier and sheath production, cable or heating tape plastic insulating layer and the base of sheath production
The manner is using the continuously extruded progress of single screw extrusion machine, the characteristics of having continuous extrusion due to extruder, so plastics
The production process of insulation and sheath is also what is be carried out continuously.
The product such as cable or heating tape is when carrying out cladding procedures, it is usually required mainly for one of technical barrier overcome is
The degree of eccentricity of insulating barrier is kept, i.e. the deviation of basic thickness of insulating layer can not be excessive, and the insulating barrier of cable or heating tape is same
Radial thickness at one cross section and varying cross-section should be consistent.Influence the bias of the product insulating barrier such as cable or heating tape
The factor of degree is broadly divided into two pieces：One is the plasticizing situation of insulating materials in itself, specifically mainly plastic molten melt temperature, insulation
The technological parameter such as material shear strain rate and plastic molten melt heating and incorporation time；Two be insulating materials cable in extrusion
With the concentricity of mould, when cable tension force not enough or it is poor with the concentricity of mould, although in the position-limiting action of inner mould core
Under, concentricity of the cable at inner mould core extrusion can be guaranteed, but cable and the concentricity at outer die casing extrusion
Can occur relatively large deviation, so as to influence the degree of eccentricity of insulating barrier.
