Background technique
Cable wire is referred to as with parallel wire unit, steel strand wires or the wirerope that high tensile steel wire forms.Cable wire is in building structure work
The industry fields such as journey, mechanical lifting, elevator play an important role.Previous cable wire needs more steel wire to twist to reach high-intensitive
System, leads to cable wire preponderance itself, causes construction weight load.Therefore, it produces a kind of closed cable wire of high intensity and weight is negative
The small cable wire of lotus is market trend.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of closed cable wire of high intensity.
The present invention adopts the following technical scheme that in order to achieve the above object：
A kind of preparation method of the closed cable wire of high intensity, includes the following steps：
(1) pretreatment；
(2) high-tensile steel wires drawing；
(3) tempering；
(4) steel spool, the large-scale stranding machine of feeding on steel wire coil；
(5) before steel wire twines into one, toward steel wire on pour leaching lubricant；
(6) steel wire for twining into one imports punch die, forms cable wire；
(7) cable wire passes through a succession of straightener, by the pressure at right angle that straightener applies, effectively eliminates steel wire before winding
By the memory of volume upper bobbin, prevent steel wire from scattering；
(8) cable wire carries out 2 pre- tensioning, and pre- tensioning for the first time is cable wire minimum breaking force to the tension that cable wire applies
40-50% keeps 50-60min, then relaxes 10-15 minutes, and second of pre- tensioning applies tension to cable wire and breaks for cable wire minimum
The 30-45% of disconnected tension, keeps 80-100min, then gradually relaxes；
(9) stabilization processes are tempered, under the tension for granting cable wire 40%-50% minimum breaking load, carry out 360-375 DEG C
Tempering；
(10) to cable wire coating.
Further, the pretreatment of the step (1) includes pickling, phosphatization.
Further, the concrete operations of the step (3) are：Steel wire is carried out simultaneously to apply tension and tempering,
Power is the 25-30% of its rupture pull force, and tempering temperature is 360-375 DEG C.
Further, step (3) tempering is divided into 2 stages, and the first stage is 360-370 DEG C, second stage
It is 370-375 DEG C.
The advantage of the invention is that：2 pre- tensioning processing extends steel cable structure effectively, improve steel cable structure high intensity and
Stability, tempering can reduce cable wire stress, help improve wirerope intensity.
