Abstract
The utility model relates to a steel-wire or cable-wire pre-former, particularly relates to an all-steel cord bunch rolling pre-former. A deformed axle and ceramic wheels are movably arranged on the supporting plate; a deformed axle and two ceramic wheels are distributed in a triangular manner; a groove-shape hole is arranged in the axial direction of the two ceramic wheels; and the deformed axle is movably arranged in the groove-shape hole by a fastening device. The fastening device comprises a bearing housing, the deformed axle is movably arranged in the bearing housing through bearing-housing adaptation; the bearing housing mates the fastening nut and fixed at a proper position in the groove-shape hole. The pre-deformation of the utility model can increase or decrease according to the requirements of users and the material consumption is reduced; the utility model is simple in structure, easy to process and produce; in addition, the utility model is a necessary tool/die for reducing production cost and can be promoted and implemented easily.
Description
One, technical field:
The utility model relates to a kind of steel wire or steel wire rope pre-former, particularly a kind of steel cord plying roller pre-former.
Two, background technology:
At present, in tire for vehicles, add the steel cord, tire wear is decreased, thus the service life of improving tire.Existing steel cord adopts three high-carbon brass plating steel wires, after every steel wire forms waveform preformed with arc form, respectively according to identical sth. made by twisting to, the out of phase twisting forms, but when the calendering unwrapping wire,, cause between three steel cords closed because technology trouble causes anti-line tension to increase, rubber can't be infiltrated between each steel wire, thereby increased the wearing and tearing between the steel wire.In the process of producing steel wire rope, will be twisted into the steel wire or burst generation distortion of rope by pre-former, form consistent waveform, the lay pitch that is fit to steel wire rope, from produce debugging, find by dissecting the analysis of steel cord, when there was rips on the cord surface, the gap in its rope between thigh and the thigh was big, and the flexural deformation of sub-thread is also big, surely load with lotus and stretch rate also than height, when increasing steel cord surface rips, the gap in the rope between thigh and the thigh increases, and the flexural deformation of sub-thread also increases, surely load with the lotus rate of stretching also increases thereupon, analyze it in the twisting process, the twisting loss is bigger, thereby is difficult to control.There is shortcoming in existing fixed formula anamorphoser: 1, pre-variable can not be adjusted; 2, because hard friction prefabricated and deformed rod along with the fluctuation of laying tension, silk or fracture of wire occur jumping in the thigh easily.
Three, utility model content:
The utility model is to overcome the deficiency that prior art exists, and designs and produce a kind of steel cord plying roller pre-former.
Technical scheme:
A kind of steel cord plying roller pre-former, be movably installed with deformed shaft and wire-crossing wheel on its gripper shoe, a deformed shaft and two wire-crossing wheel distributions triangular in shape on gripper shoe, be provided with slotted hole on two wire-crossing wheel symmetry axis directions, deformed shaft is installed in the described slotted hole by device for fastening is movable.
Described device for fastening comprises bearing holder (housing, cover), and deformed shaft is installed in the bearing holder (housing, cover) by the bearing holder (housing, cover) match activities, bearing holder (housing, cover) with tighten up nut and cooperate and be fixed in the slotted hole on the certain position.
On two wire-crossing wheel center line connecting directions on the described gripper shoe, be respectively equipped with the strip shape regulating tank of two symmetries, two wire-crossing wheel axles are installed in the corresponding strip shape regulating tank by device for fastening respectively.
Described two wire-crossing wheels are movably arranged on the gripper shoe by the axle supporting way, and its position on gripper shoe is along the slotted hole center line symmetry of deformation wheel.
The beneficial effects of the utility model:
1, steel cord plying roller pre-former of the present utility model, pre-variable can increase with user's standard difference or reduce.
2, steel cord plying roller pre-former of the present utility model, in use, deformed rod is done 360 ° of rotations under the drive of pre-stranding, reduces deformed rod and the friction of stranding in advance to greatest extent, has overcome jumping silk and the fracture of wire defective in the twisting.
3, steel cord plying roller pre-former of the present utility model, the minimizing of adjusting frequency, completely the wheel rate increases, and the material consumption reduces.
4, steel cord plying roller pre-former of the present utility model, simple in structure, processing and manufacturing easily is a stabilized product quality, the requisite moulds of industrial equipment that reduce production costs, and is beneficial to very much promotion and implementation.
