Description
Technical field
The utility model relates to a kind of pressurizing unit of producing the facial-contracted wire rope rope strand.
Background technology
In the prior art, producing facial-contracted wire rope rope strand mode has following several:
1, fixing whole mould hubbing
With fixing whole mould thigh is carried out plastic compression deformation line contact thigh is become face contact thigh.Warp tool generally is installed in the relevant position between Bunching machine Forming die and the draw-gear.Steel wire becomes thigh and compression almost to carry out simultaneously.Adopt this method tube reducing compression, be easy to before mould, occur " lantern " phenomenon.
2, rotary integral mould hubbing
This method is with two whole moulds that rotate in the opposite direction thigh to be carried out the plastic pulling compression, thereby line contact thigh is become face contact thigh.Adopt this method that thigh is carried out plasticity crimp, compare with fixing whole mould, traction wheel tractive force reduces by 30% approximately, can improve 2～9 times life of the die, and, thereby the face contact is improved about 30% a burst fatigue life because the surface quality of the face of making in this way contact thigh is more much better than fixed die drawing.The shortcoming of this method is a flow of metal stress state complexity, and required Bunching machine tractive force is still bigger, and compressible strand diameter is less, and whole mould spin friction power is big, and speed ratio is difficulty, and practical application is restricted.
3, forge method
To steel wire rope or strand implement to forge and be strand and steel wire rope carries out the new technology that plasticity is compressed.The method that employing forges thigh is used for production face contact strand, can avoid whole die drawing to pull out and roller draws in many troubles of equipment apolegamy and technological operation aspect; Comparatively speaking, simple, convenient, the deformation ratio of steel wire is more even in strand.It strand is that the thigh that will be twisted into directly enters and carries out plastic compression deformation in the swager and become face contact strand that line contact thigh forges into the face contact.Because drum speed is very high when forging, can make that steel wire produces uniform plastic deformation in the thigh, strand diameter tolerance be easy to control.But this mode of production need have the tool of production-swager of specialty, the restriction that is subjected to the position is installed on existing equipment, and input is bigger, and production efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, easy to operate, three roller pressurizing units of the production facial-contracted wire rope rope strand that yield rate is high, this device has overcome produces the plastic deformation of facial-contracted wire rope rope strand steel wire inhomogeneous, burst footpath tolerance and the uppity problem of ovality in the prior art
For achieving the above object, the utility model is by the following technical solutions:
A kind of three roller pressurizing units of producing the facial-contracted wire rope rope strand, this device is made of a plurality of squeeze unit, each squeeze unit is made of chuck, roller frame, pressure roller, and the roller frame is installed on the chuck jaw of each chuck, and pressure roller is installed on the roller frame and can rotates around roll shaft by roll shaft; A plurality of squeeze unit are connected and fixed by connecting plate, and the pressure roller center that makes each squeeze unit is on same axis, and the pressure roller pass is 1/3rd circles, and the pass of three pressure rollers forms whole round pass.
Described squeeze unit is 2～8.
The pressure roller difference angle of the adjacent squeeze unit that connects on the described connecting plate is 30-60 °.
Rolling bearing is installed in the described pressure roller to be cooperated with roller bearing.
Compared with prior art, the beneficial effects of the utility model are:
1, the rack section of this pressurizing unit adopts lathe chuck, and it has precession simultaneously of three rollers and self-locking property, design easyly, need not to increase external equipment, can be directly use having now to make on the equipment, greatly reduces equipment cost
2, the design of this pressurizing unit can satisfy that steel wire produces uniform plastic deformation in the strand wire, the diameter tolerance of thigh and ovality are easy to control, and the deformation extent of rope strand can satisfy the technological requirement of steel wire rope, are convenient to operation adjustment, need not repeatedly to adjust the production efficiency height in the production process.

Fig. 4 is the installation diagram of roller frame and chuck.
The specific embodiment
See Fig. 1-Fig. 4, a kind of three roller pressurizing units of producing the facial-contracted wire rope rope strand, this device is made of 2～8 squeeze unit, each squeeze unit is made of chuck 1, roller frame 2, pressure roller 4, on the chuck jaw 3 of each chuck, be welded with roller frame 2, pressure roller 4 is installed on the roller frame 2 by roll shaft 5 can rotate (Fig. 2, Fig. 3) around roll shaft, and rolling bearing 6 is installed in the pressure roller 4 cooperates with roller bearing 5.
A plurality of squeeze unit are connected and fixed by connecting plate, and the pressure roller center that makes each squeeze unit is on same axis, and the pressure roller pass is 1/3rd circles, and the pass of three pressure rollers forms whole round pass.Squeeze unit makes all pressure rollers all in the same direction along the fastening connection of same axis, the pressure roller of adjacent chuck staggers 30～60 ° mutually, this angle is decided according to the number of squeeze unit, in the time of chuck jaw 3 inside precession drive pressure roller 4 inwardly extruding reach compacting strand purpose.
During work, the pass center of three pressure rollers 4 of each squeeze unit is adjusted by screw mandrel screw regulator, made it on same center line, and overlap with the Operation Centre line of rope strand.Determine the drafts and the extruding passage of good every time pressure roller 4.Draw the rope strand motion by traction wheel, chuck jaw 3 inside precessions reach compacting strand purpose, and each squeeze unit that is crisscross arranged by different angles makes the surperficial generation of rope strand plastic deformation successively, form face contact thigh even, polishing.
