Description
Technical field
The present invention relates to cable production field, more particularly, it relates to a kind of self-supporting cable manufacture mould and
Manufacturing process.
Background technology
At present, self-supporting cable is as the connection of driving electric block and control cable, suitable for dry or moist interior
It is various electrically installation；In view of its special flexible design, it apply also for unstressed sustained release can mandatory guidance left and right Fei Lian
Installation or fixed laying under continuous property motion, but existing self-supporting cable is unable to reach requirement at low temperature, at low temperature
When separating cable, easily leader cable is torn, phenomena such as causing shield effectiveness to reduce.
The content of the invention
It is existing above-mentioned it is an object of the invention to solve the problems, such as, there is provided a kind of self-supporting cable manufacture mould and manufacture
Technique.
To realize object above, the technical scheme is that a kind of self-supporting cable manufactures mould, including cable punch-pin
With cable cavity plate, punch chamber is set on described cable cavity plate, sets master to portal on described cable cavity plate end face, it is described
Main side of portalling, which is set, time portals, and described master is portalled and sets passage between time portalling, the connection of described passage is main portal with
It is secondary to portal, go out nose end setting chamfering close to time on described passage.Portal in the master of self-supporting cable manufacture mould and portal with secondary
Between passage on, close to time go out nose end set chamfering, thus make on the dowel of messenger wire and main line formed a tear it is thin
Weakness, when tear, it can be torn along the weak spot, a guiding function played, so as to ensure that the sheath skin of main line
Be not torn and be not in tear depression.
Optionally, the width for the sharp corner that the chamfering of described passage is formed with passage is L, and described L scope is
0.28mm-0.35mm.L is most narrow width after passage chamfering, the data minimum data 0.28mm obtained through overtesting, less than
In the case of 0.28mm, self-supporting cable easily causes messenger wire and is automatically separated with main line during transport or carrying, loses
The effect of self-supporting cable has been gone, in the case of more than 0.35, when separating messenger wire with main line, has easily been torn out main line recessed
Fall into, or even tear, decline the function of shielding of cable, and through overtesting, when L numerical value is 0.32mm, can effectively prevent
Only messenger wire automatically disengages with main line, and and can ensures that depression or even the situation of tear occurs in main line.
Optionally, described cable punch-pin includes convex mould base and punch-pin mouth, and described punch-pin mouth is corresponding with punch chamber, institute
The punch-pin mouth stated is fixedly connected with convex mould base.Convex mould base is used for solid punch mouth, and punch-pin mouth is engaged to form plastic cement with punch chamber
Chamber, for manufacturing the external insulation layer of cable.
Optionally, main line hole and time string holes be set on described cable punch-pin, described main line hole with lead portal it is corresponding,
Described secondary string holes is corresponding with time portalling.It can so ensure that cable fast and effectively manufactures.
Optionally, described main line chamber is arranged on forming cavity including forming cavity, parcel chamber and feed cavity, described parcel chamber
Between feed cavity.Feed cavity is used for armor and the material of clad enters, and parcel chamber is used to be wrapped up on cable, is molded
Chamber is used for the shaping of cable and packed tightly.
A kind of cable manufacturing process that mould is manufactured using above-mentioned self-supporting cable, it is characterized in that, comprise the following steps：
71）Raw metal is continuously suppressed by compacting tool set, the wire of size needed for acquisition；
72）Inner insulating layer will be coated by extrusion molding mode outside the wire；
73）By step 72）Outside the product of acquisition armor is coated by working out armoring machine；
74）By step 73）The product and self-supporting line of acquisition manufacture mould by self-supporting cable and coat external insulation layer.
Optionally, described armor includes internal shield, outer conductor layer and water blocking layer.
Optionally, external shielding layer is set inside described external insulation layer, and described external shielding layer is fixed with external insulation layer to be connected
Connect.
The invention has the advantages that：Self-supporting cable manufacture mould master portal and it is secondary portal between passage
On, go out nose end setting chamfering close to time, thus make to form a tear weak spot on the dowel of messenger wire and main line, tearing
When, can along the weak spot tear, play a guiding function, so as to ensure that the sheath skin of main line be not torn and
It is not in tear depression.
