The flow chart of the cable jacket external diameter method of adjustment that Fig. 1 provides for the embodiment of the present invention；
Fig. 2 adjusts the structural representation of system for the cable jacket external diameter that the embodiment of the present invention provides.
Detailed description of the invention
The embodiment of the invention discloses a kind of cable jacket external diameter method of adjustment, to efficiently solve cable jacket external diameter very
The uniform problem of difficult control.The embodiment of the invention also discloses a kind of cable jacket external diameter and adjust system.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to the flow chart of the cable jacket external diameter method of adjustment that Fig. 1, Fig. 1 provide for the embodiment of the present invention, need
Bright, the step 100 in Fig. 1 represents precedence relationship with step 200, it is also possible to be inverted or arranged side by side.
In a kind of specific embodiment, present embodiments provide a kind of cable jacket external diameter method of adjustment, i.e. pass through the party
Method, the extrusion molding set diameter that the adjustment later stage extrudes.Concrete, the method comprises the steps:
100: obtain sheath internal diameter R3, set sheath target external diameter R2。
Wherein R3The internal diameter of cable jacket referred to, and the outside of the inner side of cable jacket and cable core fits, so R3Should
Equal with the external diameter of cable core, because conductor assembly outer diameter is changeless, so one-shot measurement or directly obtained by other approach
Take.Wherein R2Should determine according to being actually needed of jacket thickness.Internal diameter and external diameter refer to diameter herein, so R2
R should be equal to3Target thickness plus twice sheath.
200: measure sheath current external diameter R1。
Wherein R1Refer to the external diameter that sheath is current, need to use survey tool to measure acquisition.Metering system has
Multiple, can be with hand dipping, it is also possible to measurement equipment is measured automatically.The position of concrete measurement can be attached at extrusion molding die sleeve
Closely, it is contemplated that, shape the most completely from extrusion molding die sleeve sheath out, it is generally required to carry out cooling and shaping through tank,
So the most preferably measure the diameter of sheath in tank rear end, even if sheath current external diameter R1For being positioned at tank rear end on sheath
The diameter at place.Wherein tank rear end refers to the one end on tank away from extrusion molding die sleeve, and is front near one end of extrusion molding die sleeve
End.It should be noted that work as R1With R2Equal, the most then without adjusting external diameter, then should be adjusted when both are unequal.Need
It is noted that this step can also perform after step 100 has performed.
300: calculate screw rod rotating speed of targetAnd control screw rod and turn by described screw rod rotating speed of target
Dynamic, or calculate cable target translational speedAnd control cable by making described cable target translational speed
Mobile, described N0For the current rotating speed of screw rod, described V0For the current translational speed of cable.
Typically when obtaining for the first time, N0、V0It is all setting speed, causes existing between extrusion molding amount and rotating speed certain inclined
Difference, therefore realizes data according to repetitive measurement and is corrected, and to obtain correction coefficient, in order to ensure the precision controlled, can make
N0For the product of the current setting speed of screw rod Yu correction coefficient, described V0Migration velocity and correction coefficient is currently set for cable
Product.
Concrete, obtaining R1、R2、R3Afterwards, it is possible to obtain the target cross section of sheath:
And obtain the departure of the sheath of sheathIf now screw speed being modified, then screw rod
The correction of rotating speedShould be by adjustment of rotational speed current for screw rod then
If now cable hauling speed being modified, then correctionThen the hauling speed of cable should be adjusted toN0For the current rotating speed of screw rod, it should be noted that the current rotating speed of screw rod can be actual
Setting value, it is also possible to be measured value；Similarly for V0Can be actual setpoint, it is also possible to be measured value.From the aforegoing it can be seen that
The most above-mentioned both of which is by being adjusted the key factor affecting cable jacket external diameter, so both is based on same
Individual inventive concept.
In the present embodiment, when extrusion molding moulds set outside cable core, R can be obtained by said method1、R2、R3Afterwards,
When needs are adjusted, side-play amount can be effectively eliminated by the adjustment of screw speed, it is also possible to by adjusting cable
Translational speed effectively eliminate side-play amount, screw speed after concrete adjustment, or the cable migration rate after adjusting is all
Can be obtained by above-mentioned formula.In sum, it is recognised that use the method, by screw speed or cable are migrated speed
Degree is accurately revised, and can effectively eliminate the side-play amount of outer diameter sheath, it is to avoid the outer diameter sheath side-play amount of cable is bigger,
And then the cable jacket external diameter uniform problem of very difficult control can be efficiently solved.
In view of a volume length of cable typically more than hundred meters, the most longer, in order in order to ensure precision, outside performing
After step 300, it is also possible to after the scheduled duration of interval, remeasure the current external diameter of above-mentioned sheath, i.e. obtain new R2.Obtaining
After taking the current external diameter of new sheath, according to this row measured value, recalculate screw rod rotating speed of target, and adjust current screw speed extremely
New screw rod rotating speed of target, or, recalculate cable target translational speed, and adjust present cable translational speed to new
Cable target translational speed.Herein it should be noted that recalculate, it should according to formulaOr
FormulaCalculate, wherein R2、R3The most constant, also should use and be originally taken value.It should be noted that predetermined
Duration should be different according to the frequency surveyed, and different.But it should be recognized that after in order to ensure that the second measured value is for adjusting
Value, when tank rear end measure external diameter time, it should make scheduled duration be not less than cable and out move to tank from extruding machine
Rear end the duration of process, to ensure that cable adjusts rear portion and is divided into the part of current measurement.
Refer to Fig. 1, Fig. 1 and adjust the structural representation of system for the cable jacket external diameter that the embodiment of the present invention provides.
In another kind of specific embodiment, present embodiments provide a kind of cable jacket external diameter and adjust system, concrete, should
Cable jacket external diameter adjusts system and includes extruding machine 1, traction machine 2, external diameter measurer 3 and controller 4.Wherein extruding machine 1 is used for
At the outside extrusion molding sheath of cable, extruding machine 1 mainly carries out extrusion molding by extrusion screw.Wherein traction machine 2 is used for drawing
Cable at the uniform velocity moves.Wherein external diameter measurer 3 is used for measuring sheath current external diameter R1.Controller 4 therein is then used for calculating
Screw rod rotating speed of targetThen control screw rod to rotate by this screw rod rotating speed of target；Or this controller 4 is used for
Calculate cable target translational speedThen control described traction machine 2 and move speed by making described cable target
Degree migrates cable and moves, it should be noted that wherein R3For sheath internal diameter, R2For the sheath target external diameter set, N0Work as screw rod
