The object of the invention is to solve existing above-mentioned problem, provide a kind of self-supporting cable mfg. moulding die and manufacturing process.
For realizing above object, technical scheme of the present invention is a kind of self-supporting cable mfg. moulding die, comprise cable punch and cable die, described cable die arranges punch chamber, described cable die one end face is arranged main portalling, described master side of portalling arranges and time to portal, described master portal and secondary portal between passage is set, described channel connection master is portalled and time to be portalled, and described passage arranges chamfering near time going out nose end.The master of self-supporting cable mfg. moulding die portal and secondary portal between passage on, go out nose end close time and chamfering is set, so just make that the dowel of messenger wire and main line forms one and tear weak spot, when tearing, can tear along this weak spot, play a guiding function, thus ensure that the sheath skin of main line is not torn and there will not be and tear depression.
Optionally, the width of the sharp corner that the chamfering of described passage and passage are formed is L, and the scope of described L is 0.28mm-0.35mm.L is width the narrowest after passage chamfering, through the data minimum data 0.28mm that overtesting obtains, when being less than 0.28mm, self-supporting cable is in the process of transporting or carry, messenger wire is easily caused automatically to be separated with main line, lose the effect of self-supporting cable, when being greater than 0.35, when being separated messenger wire and main line, easily main line is torn out depression, even tear, the function of shielding of cable is declined, and through overtesting, when the numerical value of L is 0.32mm, can effectively prevent messenger wire and main line from automatically disengaging, the situation that main line there will be depression and even tears can be ensured again.
Optionally, described cable punch comprises convex mould base and punch mouth, and described punch mouth is corresponding with punch chamber, and described punch mouth is fixedly connected with convex mould base.Convex mould base is used for solid punch mouth, and punch mouth matches with punch chamber and forms plastic cement chamber, for the manufacture of the external insulation layer of cable.
Optionally, described cable punch is arranged main line hole and time string holes, described main line hole with main portal corresponding, described secondary string holes with secondary portal corresponding.Can ensure that cable manufactures fast and effectively like this.
Optionally, described main line chamber comprises forming cavity, parcel chamber and feed cavity, and described parcel chamber is arranged between forming cavity and feed cavity.The material that feed cavity is used for armour and coating layer enters, and parcel chamber is used for cable to wrap up, and forming cavity is used for the shaping of cable and packs tightly.
Utilize a cable manufacturing process for above-mentioned self-supporting cable mfg. moulding die, it is characterized in that, comprise the following steps:
71) raw metal is suppressed continuously by compacting tool set, obtain the wire of required size;
72) by extrusion molding mode by outside for described wire coated inner insulating layer;
73) by step 72) product that obtains outside is by the coated armour of establishment armoring machine;
74) by step 73) product that obtains and self-supporting line be by the coated external insulation layer of self-supporting cable mfg. moulding die.
Optionally, described armour comprises internal shield, outer conductor layer and water blocking layer.
Optionally, described external insulation layer inside arranges outer shielding layer, and described outer shielding layer is fixedly connected with external insulation layer.
The present invention has following beneficial effect: the master of self-supporting cable mfg. moulding die portal and secondary portal between passage on, go out nose end close time and chamfering is set, so just make that the dowel of messenger wire and main line forms one and tear weak spot, when tearing, can tear along this weak spot, play a guiding function, thus ensure that the sheath skin of main line is not torn and there will not be and tear depression.
