Technical Field
[0001] The invention relates to a technique for using a pneumatic gun for tire maintenance, and in particular to a wire-corroding liquid, a device and a method suitable for rapid corrosion of steel wires. Background Art
[0002] As the requirements for single-filament strength in the steel cord industry become higher and higher, the wire diameter becomes thinner and thinner, and products are constantly upgraded and iterated, UT-strength steel wire has been industrialized, and MT-strength steel wire has also become a research hotspot for the next generation of products.
[0003] As the single wire strength increases, the carbon equivalent of the steel wire gradually increases. At the same time, the plasticity of the steel wire also tends to decrease.
[0004] At present, the existing method of sharpening is that the front-line production personnel put the steel wire on the existing sharpening column of the water tank drawing platform and rub the steel wire back and forth with force, so that the steel wire is heated and then pulled thin and broken under the action of external force. With the increase of carbon equivalent and strength of steel wire, the success rate and efficiency of traditional sharpening operation have been greatly reduced, and it also poses certain challenges to the physical fitness and operating skills of front-line production personnel. Summary of the invention

[0011] Based on the above solution, preferably, the bottom of the reaction spoon is hollowed out to hold CaO particles.
[0012] Based on the above solution, preferably, the bottle stopper is made of glass.
[0013] A method for sharpening a steel wire, using the aforementioned wire-curing liquid and device, Add the silk solution into the solution bottle; Put the CaO particles into the reaction spoon, pass the pull rod with the reaction spoon through the bottom of the bottle stopper, and then insert it into the mouth of the solution bottle together with the bottle stopper. The reaction spoon does not contact the silk solution. Grind the part of the steel wire to be reacted to remove the brass coating on the surface of the steel wire; Insert the reaction spoon into the silk-making solution, and let the CaO in the reaction spoon react with the sulfuric acid in the silk-making solution to generate heat, so that the temperature of the silk-making solution rises to 50±5℃, and quickly lift the telescopic rod until the reaction spoon is no longer in contact with the silk-making solution to stop the reaction; Insert the polished and plated steel wire into the wire-making liquid through the corresponding hole of the bottle stopper.

[0015] It has fast response, high efficiency, reduces the labor intensity of front-line production personnel, and reduces safety risks. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 is a cross-sectional view of the present invention; Figure 2 It is an overall diagram of the present invention. DETAILED DESCRIPTION
[0017] The present invention will be further described below by way of examples, but the scope of the present invention is not limited thereto.
[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0019] A wire-corroding liquid and device suitable for rapid corrosion of steel wire, such as Figure 1-2As shown, it includes a steel wire 1, a pull rod 2, a solution bottle 3, a bottle stopper 4, a silk-making solution 5, a vent hole 6, and a reaction spoon 7.
[0020] The steel wire 1 is a brass-plated steel wire. After being polished to remove the plating layer, it is inserted into the silk-making liquid 5 through the corresponding hole of the bottle stopper 4 to react. The reaction chemical formula is: Fe+H2SO4=FeSO4+H2↑, H2+H202=2H20.
[0021] The pull rod 2 is connected to the reaction spoon 7 through the pull rod mounting hole of the bottle stopper 4. The material is polytetrafluoroethylene. The pull rod can move up and down relative to the bottle stopper. It can be manually held or raised and lowered by gas-assisted tooling. The reaction of CaO in the reaction spoon 7 and the silk-making liquid 5 is controlled by the up and down movement of the pull rod. The reaction chemical formula is CaO+H2SO4=CaSO4+H2O. It is an exothermic reaction. The silk-making liquid 5 is heated to 50°C, which can be slightly higher or slightly lower than this temperature. Provide conditions for the subsequent rapid reaction of steel wire and sulfuric acid.
[0022] The solution bottle 3 is made of transparent polytetrafluoroethylene and is used to contain the silk-making solution 5 .
[0023] The bottle stopper 4 is made of glass and has a wire insertion hole, a vent hole 6 and the pull rod mounting hole. The bottle stopper 4 is nested and sealed with the mouth of the solution bottle 3.
[0024] The silk-making liquid 5 is peroxysulfuric acid, and its specific composition (mass fraction) is 50%-70% sulfuric acid, 5%-10% hydrogen peroxide, and the balance is water. Hydrogen peroxide can enhance the oxidizability of sulfuric acid and increase the reaction rate. At the same time, the heat generated by the reaction of CaO and H2SO4 in the early stage promotes the temperature of the silk-making liquid 5 to further increase the reaction rate.
[0025] The vent hole 6 is used to discharge a small amount of H2 generated by the reaction between the steel wire 1 and the chemical liquid 5.
[0026] The bottom of the reaction spoon 7 is hollowed out for containing CaO particles.
[0027] How to use silk liquid to tip: 1. Mix 50%-70% sulfuric acid, 2%-8% hydrogen peroxide and the rest of water into a silk solution and add it into the solution bottle.
[0028] 2. Put the CaO particles into the reaction spoon, pass the telescopic rod with the reaction spoon through the bottom of the bottle stopper, and then insert it into the mouth of the solution bottle together with the bottle stopper. The reaction spoon does not contact the silk solution.
[0029] 3. Grind the area of the steel wire to be reacted to remove the brass coating on the surface of the steel wire.
[0030] 4. Insert the reaction spoon into the silk-making liquid, let the CaO in the reaction spoon react with the sulfuric acid in the silk-making liquid to generate heat, so that the temperature of the silk-making liquid rises to about 50°C, and quickly lift the telescopic pull rod until the reaction spoon is no longer in contact with the silk-making liquid to stop the reaction.
[0031] 5. Insert the polished steel wire into the wire-making liquid through the corresponding hole of the bottle stopper. The steel wire and the wire-making liquid react quickly. During this process, the steel wire immersed in the wire-making liquid gradually becomes sharper and thinner. Observe the state of the steel wire with the naked eye from the outside.
[0032] 6. After reacting for 3-5 minutes, the part of the steel wire immersed in the sulfuric acid solution is corroded and becomes sharp. After corrosion cleaning and polishing, it becomes a white needle. Take out the steel wire, clean it, and then pierce the mold. Example
[0033] The steel wire with a diameter of 1.8 mm was pointed with a wire-making liquid.
[0034] 1. Mix 65% sulfuric acid, 5% hydrogen peroxide and 30% water into 200ml of silk-making solution and add it into the solution bottle.
[0035] 2. Put 20g of CaO particles into the reaction spoon, pass the telescopic rod with the reaction spoon through the bottom of the bottle stopper, and then insert it into the mouth of the solution bottle together with the bottle stopper.

[0039] 6. After 4 minutes of reaction, the part of the steel wire immersed in the sulfuric acid solution is corroded and becomes sharp. After corrosion cleaning and polishing, it becomes a white needle. Take out the steel wire, clean it, and then pierce the mold. Example
[0040] The steel wire with a diameter of 1.40 mm was pointed with a wire-making liquid.
[0041] 1. Mix 60% sulfuric acid, 3% hydrogen peroxide and 37% water into 200ml of silk-making solution and add it into the solution bottle.
