Description

Cable forming machine

Technical field

The present invention relates to a kind of instruction cable fabrication machine, described cable is especially made by steel wire.It in a plurality of application of these cables, is the replacement cable for the rack of motor vehicles.

Background technology

By manufacturing wirerope from being supplied to the bobbin of the steel wire weaving unit, steel wire is wrapped on weaving unit with specific spacing, and normally (non-limiting) is around wound around by they being wrapped in to plastic core.Bobbin is arranged on the one or more spool carrier frames in planet spool system around the common trunnion axis that is coaxially installed to braiding machine there, and framework rotates so that a plurality of line little by little adopts their knitting position about weaving unit around common trunnion axis.Can coaxially supply plastic core with described axle, line weaves around described plastic core.The cable being woven into is thus fed on the collection spool that is arranged in machine end.

The spool carrier frame forming section that the present invention be more particularly directed to feeder device, it is supplied to cable forming machine by line.

When planet spool rotates around braiding axle, be easily, they are side by side rotated along contrary direction with identical angular speed, to avoid line around they self axle distortion, this distortion will be in cable inner accumulated distorting stress, and generation may destroy their mechanical strength and the inner tensions in service life.Therefore, when each, independently the nearest pattern of these machines is to have certain mechanism that is intended to make the reverse rotation of spool to synchronize with the rotary speed of spool carrier frame in order to keep the position, angle of described line and consistent with cable line when rotation.

Known mechanism is by utilizing the rotatablely moving by means of gear by spool reverse rotation is carried out synchronously of framework self, and what described gear made by intermediate conversion gear that each spool is engaged to spool carrier frame has the central gear of same diameter with the former.Although this mechanism guaranteed spool and will keep with respect to machine their orientation together with framework when rotating, except the cost of gear train with safeguard they have also increased the energy requirement installing widely.

Summary of the invention

The present invention has improved cable fabrication machine in this respect by being provided for the reverse rotation system of spool, and reverse rotation system does not require from its energy and do not require auxiliary energy.Alternatively, because braiding axle is level, therefore new system is utilized gravitational field.According to the present invention, spool is arranged on framework with free rotating manner and is provided with the directed eccentrically mounted weight part that keeps spool balance weight assembly, has avoided thus the aspect-stabilized rotation of line when line is supplied to weaving unit.By this kind of mode, especially without any additional-energy load in the situation that (owing to comparing with the quality of gear train, the additional mass being embodied by counterweight does not mean that significant driving-energy load), spool will keep their vertically-oriented and line non-warping in the situation that, to weave progressively, and the cable therefore forming is without any structural internal tension.

The specific embodiment

La cable forming machine shown in Fig. 1 is formed by the unit of three sharp outlines.First module is feeder unit 11, and it supplies with a plurality of lines 13 for the manufacture of cable 15.These lines 13 offer braiding machine device 17 with the form of bundle, and braiding machine device consists essentially of ring 19, and line 13 passes described ring together with center plastic core 21.Unit the 3rd is collector unit 23, and it little by little pulls and is wrapped in the cable of collecting on spool 25, and described cable is by forming from encircling 19 weaving threads out.

For line being supplied to the device of weaving unit 19, comprise by two rotating frames or

wheel

27A and 27B(assembly 27) feeder unit that forms, as better shown in Figure 2, described in each, rotating frame or wheel are formed by nine spokes that formed by the vertical smooth elongate rod 29 of radially giving prominence to from hollow tubular axle 31 or equidistant arm, described hollow tubular axle 31 is shared by two frameworks, and in its hole, have the plastic core for cable 15, described cable is supplied with by single spool 33.Spool 35 is arranged on the end of spoke 29, and it keeps up to 18 bobbins 15.

Axle 31 joins only 1HP(1 horsepower to by gear 37, and this is to make to take turns 27 related their enough energy of spool 35 rotations) gear motor 39.When spool is empty, heavily about 4.5kg, and as the heavily about 6kg of full load bobbin, they form the initial gross weight of similar 11kg on the end of each arm 29.Ideally, due to being uniformly distributed of these load, each momentum of taking turns the increase of nine arms 29 of 27 is compensated, but this system predicted when the line 13 with lesser amt is manufactured cable 15, may there is the resultant load except zero.The diameter of spool 35 is enough large so that the inner wire 13 of bobbin can be exceedingly crooked, avoids thus in braiding process the inner tensions of accumulation on online 13.

According to the preferred embodiment of the present invention shown in Fig. 3, each spool 35 is arranged on the arm 41 of support 43 in the mode of freely rotating around rotating shaft 45, rotating shaft 45 has nut 47 on its end, described nut is fastened on described rotating shaft on support 43, and except for fastening, this nut also has the additional function as the brake of spool 35 in online 13 situations that should rupture, and has avoided thus residue line to discharge by inertia.The arm 41 of support 43 is connected to horizontal element 49, described horizontal element is with free rotating manner pivotable on the axle sleeve 51 that crosses spoke 29 ends, on its opposed end, have vertical lever arm 52, vertically lever arm 52 has the eccentrically mounted weight parts 53 that dangle therefrom, and it is as counterweight.Lever arm 52 is for example by welding 54 nut or the sleeves 55 and fixing by flat head screw 57 that are attached on the end that is positioned at pivot member 49.

Verified, the counterweight 53 of 1.2kg is enough to form sufficient moment of inertia to keep spool 35 to be pivotally fixed on the end of corresponding swiveling wheel 27.The effect of expectation has been shown in Fig. 4, it shows in spool 35 with solid line, its counterweight 53 Shang given position, end pivotable of spoke 29 of in wheel 27, then the identical spoke of locating at diverse location 29 ' has by wheel 27 and rotates to the different deflection that special angle forms, this illustrates spool 35 and will keep identical given spatial orientation, whichever can be initial, it is proved to be for wheel 27 and rotates completely with 360 °, is the unbalanced result producing with respect to pivotal axis 49 by eccentrically mounted weight 35.

The ring of knit unit 17 comprises sleeve pipe 19, its be in this case fix and with tubular shafts 31 coaxially to directly, to receive the plastic wire 21 that forms cable core 15 in its hole, described cable core 15 is collected spool 25 and longitudinally pulls with uniform speed.Meanwhile, the through hole 59 of the equal number of making on 18 lines of spool 35 or the circle of filament 13 by the same diameter on rotating disc 61, described rotating disc be attached to tubular shafts 31 front end or with continuously so that its by with wheel 27 identical angular speed rotations.Line 13 from arbitrary arm 27 all alternately passes described hole 59, and the former is arranged as their spoke 29 is scattered.

In this way, when line 13 approaches ring or sleeve pipe 17 line 13 spread equably and, due to rotatablely moving of feeder device 11, they are to be little by little wound around and to be enclosed in by the definite pitch of longitudinal velocity/rotary speed ratio around plastic core 21.Easily, drive the identical power source 39 of rotating frame 27 that cable is moved to and collected on spool 25.

Self-evident, when the present invention is put into practice, in the situation that not departing from spirit of the present invention, the difference about material, size and layout can be revised and is incorporated in embodiment described herein.In addition, counterweight may optionally comprise the discrete portions 53 of the end of the pivotal axis 49 that is connected to spool 35, but by make the spool unbalanced any device of setovering all will be enough to realize the object being intended to of the present invention with respect to spool pivotable 35.
