Description
Technical field
The present invention relates to a kind of cable or heating tape product technical field of processing equipment, especially a kind of automatic adjustment is concentric
The cable insulation extrusion process of degree.
Background technique
The processing technology of the products such as cable or heating tape mainly includes drawing, process and cladding: drawing is mainly used for processing
The conductor wire core of cable or heating tape makes metal bar or thicker metal wire be forced through mold, metal bar by pulling force effect
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 overcome skin effect existing for single cable or heating tape core, and more single lines are pressed
According to scheduled direction weave in；Cladding be primarily referred to as outside the conductor thread core of the products such as cable or heating tape wrap up one layer or
Multi-layer insulation and jacket material, thermoplastic superior performance have good process industrial art performance, in particular for electricity
Simple process when cable or heating tape extrude insulating layer and sheath production, the base of cable or heating tape plastic insulating layer and sheath production
The method is using the continuously extruded progress of single screw extrusion machine, since extruder has the characteristics that continuously to squeeze out, so plastics
The production process of insulation and sheath is also to be carried out continuously.
The products such as cable or heating tape are when carrying out cladding procedures, it is usually required mainly for one of technical problem overcome is
The degree of eccentricity of insulating layer is kept, i.e. the deviation of basic thickness of insulating layer cannot be excessive, and the insulating layer 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 products insulating layer such as cable or heating tape
The factor of degree is broadly divided into two pieces: first is that the plasticizing situation of insulating materials itself, specifically mainly plastic molten melt temperature, insulation
Material shear strain rate and the technological parameters such as plastic molten melt heating and incorporation time；Second is that insulating materials cable when squeezing out
With the concentricity of mold, when cable tension not enough or with the concentricity of mold it is poor, although in the position-limiting action of inner mould core
Under, the available guarantee of concentricity of the cable at inner mould core extrusion, but the concentricity at cable and outer die casing extrusion
Relatively large deviation can occur, to influence the degree of eccentricity of insulating layer.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of cable insulations of automatic concentricity adjusting to squeeze out work
