Background technology
Steel bead wire is that the surface that high-carbon steel supports is coated with the steel wire of red copper or bronze, and it is high that steel bead wire has intensity, good toughness, and the excellent and linearity well of fatigue behaviour, is mainly used in tyre rim as enhancing share price material.
In traditional tempered bead steel wire manufacture process, in order to improve further the rustless property of steel bead wire, ageing resistace and and rubber between adhesion, steel bead wire first will carry out Steel Wire Surface process usually, and then carries out plating.
At present, one of the prior art is carried out surface-treated method to steel wire and is: carry out cathodic pickling process to steel wire, removes oxide-film and the greasy dirt of Steel Wire Surface.The shortcoming of the method is: because cathodic pickling exists the problem such as high pollution, high energy consumption, do not meet national industrial policies; In addition, change plating speed in steel bead wire production process fast, conventional electrolysis pickling is difficult to oxide on surface and the greasy dirt of fully removing steel bead wire, the binding ability of metal deposition process and coating and steel wire when being unfavorable for that follow-upization is plated.
Summary of the invention
The embodiment provides a kind of device steel wire being carried out to polishing, to realize carrying out effective surface treatment to steel wires such as steel bead wires.
Steel wire is carried out to a device for polishing, comprising:
Duct mould, at steel wire through duct mould inside, the micro-sword tooth utilizing duct mould inside to arrange carries out prestripping to the oxide skin of Steel Wire Surface;
Sized flap wheel, for passing described duct mould through sized flap wheel at steel wire, utilizing the surface of the steel wire of the wheel of the sized flap wheel rotated after prestripping to carry out polishing, removing the oxide skin of Steel Wire Surface.
The technical scheme provided as can be seen from the embodiment of the invention described above, the mode that the embodiment of the present invention combines by adopting micro-sword tooth and sized flap wheel, carry out comprehensive physics to the surface of steel bead wire to peel off at a high speed, fully can remove surface scale of steel wire, realize Steel Wire Surface mirror-polishing.Wire-drawing lubrication film residual for Steel Wire Surface can also be removed, to guarantee that steel wire obtains good bonding force.

In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
A kind of concrete structure figure steel wire being carried out to the device of polishing that Fig. 1 provides for the embodiment of the present invention, in FIG, 1: steel bead wire, 2: control power unit, 3: duct mould, 4: micro-sword tooth, 5: sized flap wheel.
Detailed description of the invention
For ease of the understanding to the embodiment of the present invention, be further explained explanation below in conjunction with accompanying drawing for several specific embodiment, and each embodiment does not form the restriction to the embodiment of the present invention.
The embodiment of the present invention goes for the steel wires such as steel bead wire, for steel bead wire, the embodiment of the present invention is described below.
A kind of concrete structure steel wire being carried out to the device of polishing that the embodiment of the present invention provides as shown in Figure 1, comprises following unit:
Control power unit 2, for carrying out the diameter of the steel bead wire 1 of polishing as required by PLC(Programmable Logic Controller, programmable logic controller (PLC)) calculate the scale thickness estimator of steel bead wire, calculate the rotating speed of sized flap wheel and the active force of micro-sword tooth according to this scale thickness estimator.Rotating speed according to the sized flap wheel calculated sends rotating speed control instruction to sized flap wheel, and the active force according to the micro-sword tooth calculated sends active force control instruction to micro-sword tooth.
In actual applications, the scale thickness of above-mentioned steel bead wire is larger, and the rotating speed of above-mentioned sized flap wheel is larger, and the active force of micro-sword tooth is larger.The thickness of oxide skin is generally at 70 μm, and the rotating speed of sized flap wheel is generally 90-200r/min, and the active force of micro-sword tooth is generally 30-80N.
Duct mould 3, adopts carbide alloy structure, is rectangle, is provided with a lot of micro-sword tooth 4 therein.During steel bead wire straightaway, first through the inside of duct mould being covered with micro-sword tooth, make micro-sword tooth act on trying hard to keep in Steel Wire Surface according to the active force control instruction of control power unit transmission to hold constant, utilize micro-sword tooth to carry out prestripping to the oxide skin of Steel Wire Surface.The diameter of above-mentioned micro-sword tooth can be 8cm, and space width can be 0.5cm.
Sized flap wheel 5, for passing described duct mould through sized flap wheel at steel wire, utilizing the surface of the steel wire of the wheel of the sized flap wheel rotated after prestripping to carry out polishing, removing the oxide skin of Steel Wire Surface.Comprise the sized flap wheel of the different polishing precision of many groups.Steel bead wire through after the mould of duct first through the sized flap wheel that polishing precision comparison is low, then through the high sized flap wheel of polishing precision comparison.The rotating speed of each group of sized flap wheel is adjusted according to the rotating speed control instruction of control power unit transmission, the steel bead wire surface of wheel after prestripping of above-mentioned many group sized flap wheels is utilized to carry out progressive polishing, finally fully remove surface scale of steel wire, realize Steel Wire Surface mirror-polishing.The diameter of above-mentioned sized flap wheel can be 25cm, and blade gap distance can be 0.7cm.
One of ordinary skill in the art will appreciate that: accompanying drawing is the schematic diagram of an embodiment, the module in accompanying drawing or flow process might not be that enforcement the present invention is necessary.
One of ordinary skill in the art will appreciate that: the unit in the equipment in embodiment can describe according to embodiment and be distributed in the equipment of embodiment, also can carry out respective change and be arranged in the one or more equipment being different from the present embodiment.The unit of above-described embodiment can merge into a unit, also can split into multiple subelement further.
In sum, the mode that the embodiment of the present invention combines by adopting micro-sword tooth and sized flap wheel, carries out comprehensive physics to the surface of steel bead wire and peels off at a high speed, fully can remove surface scale of steel wire, realize Steel Wire Surface mirror-polishing.Wire-drawing lubrication film residual for Steel Wire Surface can also be removed, to guarantee that steel wire obtains good bonding force.
The embodiment of the present invention, compared with existing steel bead wire surface acid-washing technique, has pollution-free, the advantage such as surface is cleaner, cost reduction, especially overcomes cathodic pickling in existing technique and there is the problem such as high pollution, high energy consumption.
Steel wire surface when patenting can cause hanging lead, traditional cathodic pickling or salt pickling, all cannot solve well and hang plumbous problem.When follow-up plating, cause coating not good, thus affecting steel wire and rubber adhesion power, lead residual for Steel Wire Surface can be carried out comprehensive physics by micro-sword tooth and multistage sized flap wheel and peel off at a high speed by the embodiment of the present invention, thus solution steel bead wire existence surface hangs plumbous problem.
