Description
Technical field
The present invention relates to steel cord or steel wire rope manufacturing technology, particularly a kind of pre-former for steel cord or steel wire rope.
Background technology
Existing engineering tyre steel cord or for lifting, the purposes steel wire ropes such as transmission are twisted with the fingers in stock technology, because cord structure is complicated, diameter is thicker, generally be not out of shape at Cheng Shengqian, between Cheng Shenghou by straightener be used for regulate Residual torsion and improve into rope form condition, production process extremely unstable, especially steel cord requires tighter structure to becoming rope quality and Residual torsion, all the more so, and strand is not out of shape, reverse and all increase intrusion adjustment by straightener, the cord that result is produced is easily loose, strike-through poor performance, not only affect production efficiency and the quality of tire producer, affect the service life of tire especially,
Some producer has recognized above-mentioned production defect, use a kind of discoid anamorphoser, this anamorphoser size is greater than a point string holes, so cord out can form a difference in height afterwards from point string holes, cord is twisted into rope after disk, has again a difference in height, thus realize distortion, the advantage of this anamorphoser is the strand that can be used for all quantity, and shortcoming is that deflection is fixed, and deflection is non-adjustable.
Also has a kind of predeformation of three-vane of flat, this predeformation is by spacer ring Heterogeneous Permutation by three of otch alloy sheets, steel wire is badly deformed before sth. made by twisting stock on distortion sheet, obtain certain deflection, this predeformation, although adjustable on wavelength and wave height deflection, but three carbide alloy sizes are completely the same, during steel wire distortion on a horizontal plane, inconsistent with steel wire shaping state, cause through last a slice anamorphoser steel wire different from front two panels with the friction of anamorphoser, in addition, steel wire directly contacts with anamorphoser, very large to Steel Wire Surface damage, above-mentioned two kinds of anamorphosers all can not realize the comprehensive adjustment to steel wire, the especially adjustment of deformation wave radian, and adjustable range is little, so limited to the regulating action of steel wire Residual torsion.
Summary of the invention
The object of the present invention is to provide a kind of pre-former for steel cord or steel wire rope, not only can realize omnibearing free adjustment, significantly can also reduce the wearing and tearing to steel wire.
For achieving the above object, technical scheme of the present invention is:
For a pre-former for steel cord or steel wire rope, it comprises, base, and on it, central authorities establish through hole, arranges a quill shaft in through hole; Upper, middle and lower adjustment plate, is respectively the Rotary-table of band centre bore, and three adjustment plate outer surfaces, form a up big and down small Rotary-table structure point-blank; Upper, middle and lower adjustment plate is sheathed on described base quill shaft, and upper and lower adjustment plate is fixedly connected on quill shaft, and middle adjustment plate is rotary structure; Each adjustment plate lateral surface circumferentially evenly arranges at least one row's screw, and the screw correspondence in upper and lower adjustment plate is arranged, namely on same straight line; Some studs, each stud wear a deformation wheel, and are locked by nut; Described stud one end is arranged at the arbitrary row's screw on the adjustment plate lateral surface of described upper, middle and lower respectively.
Further, described lower adjustment plate and quill shaft threaded engagement, and also establish a lock nut under lower adjustment plate, promote lower adjustment plate adjustment plate upwards thus in locking by twist-lock nut.
Preferably, described upper and lower adjustment plate lateral surface circumferentially evenly arranges 2 ~ 3 row's screws.
Preferably, described upper, middle and lower adjustment plate often being arranged screw quantity is 3 ~ 15.
Preferably, point-blank, its outer surface becomes 15 ° ~ 30 ° angles to described upper, middle and lower adjustment plate outer surface with central axis.
Preferably, on described each stud around its deformation wheel lateral surface freely rotated be arcs of recesses.
Preferably, described deformation wheel two ends diameter 7 ~ 11mm, deformation wheel mid diameter 5 ~ 7mm.
Preferably, described stud, deformation wheel are carbide alloy material.
The present invention's upper and lower adjustment plate deformation wheel position point-blank, between the position of intermediate deformation wheel and this straight line, shape has a certain degree, steel wire or cord planar become trigonometric function graph shape by distortion successively after the deformation wheel in lower adjustment plate, middle adjustment plate, upper adjustment plate, if steel wire or strand rotate, and curl in space.
Cord is before twisting, successively respectively through the deformation wheel in lower adjustment plate, middle adjustment plate, upper adjustment plate, wherein up and down adjustment plate be symmetrically distributed with 2-4 can fixed bolt screw, on be fixed therein screw of stud symmetry, stud in middle adjustment plate is fixed in adjustment plate, makes to have different angles between its from the deformation wheel in upper and lower adjustment plate by the rotation of adjustment plate.Therefore the present invention is by adjustment plate in rotation, steel wire or strand is made to obtain the deflection of different wave height, adjust the position of upper and lower adjustment plate upper stud, obtain the size of the deflection of different wave length, adjustment deformation wheel diameter, obtain crest and the trough of different radian, thus reach steel wire or strand deflection is omnibearing freely controls, in addition because steel wire or strand are out of shape in deformation wheel, the coefficient of friction of steel wire or strand and anamorphoser is little, improves the damage of anamorphoser to steel wire.
The present invention compared with prior art has following features and advantage:
1. deflection is comprehensive adjustable, can be regulated the wavelength of steel wire or strand by the position of the stud of the upper and lower adjustment plate of the change of symmetry; The wave height of monofilament or strand can be regulated after then certain position is fixed by adjustment plate in rotating; By adjusting the diameter of deformation wheel, the radian of steel wire or strand crest and trough can be regulated.
2. the present invention's three adjustment plate outer surfaces point-blank, 15 °-30 ° are become to spend with the center line of cord traffic direction, steel wire state when this out becomes to restrict from noseplate with cord is afterwards consistent, and deformation wheel also has certain free degree up and down at stud, make cord further and become rope form state and mate, be conducive to the one-tenth rope quality stability of cord.
3. present invention uses the deformation wheel freely can rotated on stud, steel wire or strand were changed over rolling friction by former sliding friction, decrease the damage to steel wire or strand, reduce intensity and coating loss.
4. the present invention is because can comprehensively regulate, and well can control in actual production to the Residual torsion of cord or steel wire rope.
