Description

Technical Field

[0001] The present application relates to the technical field of steel wire production, and in particular to a galvanized steel wire production process. Background Art

[0002] During the production of steel wire, various coatings are added to the wire to meet different usage conditions. However, during the coating process, the oxide layer attached to the surface of the steel wire needs to be removed, and existing removal methods are not effective. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a galvanized steel wire production process, which has the advantage of better removal of the oxide layer.

[0004] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0005] A galvanized steel wire production process comprises the following steps: a pay-off step of unwinding the steel wire; a removal step of cracking the oxide layer on the surface of the steel wire; a pre-washing step of brushing the oxide layer on the surface of the steel wire while performing acid cleaning; a pickling step of pickling the steel wire with acid; a water washing step of washing the steel wire; a wire drawing step of drawing the steel wire; a pickling step of pickling the steel wire; a water washing step of washing the steel wire; a coating step of coating the steel wire; a water washing step of washing the steel wire; a drying step of drying the steel wire; and a coiling step of coiling the steel wire.

[0006] By adopting the above technical solution, that is, by adding a pre-washing step when removing the oxide layer, the steel wire surface is brushed and then acid-cleaned, and then pickled again, the oxide layer is well removed.

[0007] In a preferred example, the present application can be further configured as follows: in the pre-washing step, it includes a brush barrel, which is vertically arranged and has bristles inside. The upper and lower ends of the brush barrel are provided with through holes for steel wire to pass through, and the acid enters the brush barrel from the through hole above the brush barrel.

[0008] By adopting the above technical solution, that is, the acid flows from top to bottom, under the action of the bristles, the oxide layer can be effectively removed.

[0009] In a preferred example, the present application can be further configured as follows: it also includes a bracket, the brush barrel is rotatably connected to the bracket, and the bracket is further provided with a driving member for driving the brush barrel to rotate.

[0010] By adopting the above technical solution, the rotation of the brush barrel drives the bristles to rotate around the steel wire, thereby removing the oxide layer.

[0011] In a preferred example, the present application can be further configured as follows: the upper end and the lower end of the brush barrel both include lower convex parts, the through hole is provided on the lower convex parts, and the lower convex parts form a chamber for accommodating acid liquid.

[0012] By adopting the above technical solution, the presence of the lower protrusion for accommodating the acid solution allows the steel wire to be immersed in the acid solution both before and after contacting the bristles, thereby further enhancing the effect of removing the oxide layer.

[0013] In a preferred example, the present application can be further configured as follows: the lower protrusion is made of a deformable material.

[0014] By adopting the above technical solution, when there is a lot of acid in the brush barrel, the lower convex part at the lower end of the brush barrel will be deformed, thereby discharging the acid.

[0015] In a preferred example, the present application can be further configured as follows: a booster cylinder is detachably connected to the brush cylinder, and the booster cylinder is sealed with the brush cylinder and the steel wire, and the booster cylinder is used to increase the acid pressure at the lower convex part.

[0016] By adopting the above technical solution, the presence of the booster cylinder increases the pressure of the acid liquid at the lower convex part, thereby accelerating the flow speed of the acid liquid.

[0017] In a preferred example, the present application can be further configured as follows: the bristles are arranged at an angle and the lower end is used to contact the steel wire.

[0018] By adopting the above technical solution, the inclined bristles are easier to rinse.

[0019] In a preferred example, the present application can be further configured as follows: a redundant step is provided between the pre-washing step and the pickling step, and the steel wire is redundantly set.

[0020] By adopting the above technical solution, the existence of redundant steps enables redundant storage of steel wires, thereby reducing the probability of downtime.

[0021] In a preferred example, the present application can be further configured as follows: the redundant steps are executed periodically, and when the redundant steps are completed, the wire-laying step is stopped, the brush cylinder stops rotating, the booster cylinder, the brush cylinder and the steel wire are in contact and sealed connection, the acid enters the lower convex part at the upper end through the booster cylinder, and increases the pressure at the lower convex part at the upper end, and enters the brush cylinder to flush the bristles, and is finally discharged from the lower convex part at the lower end.

[0022] By adopting the above technical solution, that is, after the redundant step is executed, the acid enters the lower convex part at the upper end through the booster cylinder and fills the brush cylinder. Under the action of pressure, the lower convex part at the lower end is deformed, so that the acid flows out quickly, thereby cleaning the bristles and the oxide layer attached to the lower convex part.

[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] The present application discloses a galvanized steel wire production process, comprising the following steps: a pay-off step of unwinding the steel wire; a removal step of breaking the oxide layer on the surface of the steel wire by a shelling device; a pre-washing step of brushing the oxide layer on the surface of the steel wire while performing acid cleaning; a redundant step of redundantly setting the steel wire, that is, pre-storing the steel wire. For example, in normal use, the steel wire is horizontal, and the pre-storage means that the steel wire is distributed in an S shape. Therefore, after the redundant step is executed, there will be more steel wires at the corresponding work station for use in subsequent steps; a pickling step of pickling the steel wire with acid; a water washing step of washing the steel wire; a wire drawing step of drawing the steel wire; a pickling step of pickling the steel wire; a water washing step of washing the steel wire; a coating step of coating the steel wire; a water washing step of washing the steel wire; a drying step of drying the steel wire; and a coiling step of coiling the steel wire.

[0027] Reference Figure 1 During the pre-washing step, a brush barrel 1 and a bracket are rotatably connected. The bracket is provided with a driving member, such as a motor, for driving the brush barrel 1 to rotate. The motor drives the brush barrel 1 to rotate via a gear drive or belt drive. The brush barrel 1 is vertically arranged, and an internal annular array of bristles 2 is arranged at an angle. The lower ends of the bristles 2 are used to contact the steel wire. The upper and lower ends of the brush barrel 1 each include a lower protrusion 3. The lower protrusion 3 is made of a deformable material, such as rubber or silicone. The lower protrusion 3 forms a chamber for containing acid liquid. The lower protrusion 3 is provided with a through hole 31 for the steel wire to pass through. The acid enters the brush barrel 1 through the through hole 31 above the brush barrel 1. In this embodiment, the lower protrusion 3 is truncated cone-shaped. The contact between the lower protrusion 3 and the steel wire can be surface contact, point contact, or line contact. In this embodiment, the lower protrusion 3 and the steel wire have contacting and non-contacting portions. For example, the through hole 31 is provided with multiple protrusions for contacting the steel wire.

[0028] A booster cylinder 4 is detachably connected to the brush cylinder 1. This cylinder is connected to the outside world via a pipe and is sealed to the brush cylinder 1 and the steel wire. This cylinder is used to increase the acid pressure at the lower protrusion 3. The booster cylinder 4 is composed of two semicircular cylindrical structures joined together (either manually or by actuators such as cylinders). A clearance hole is provided for the steel wire to pass through. Rubber or silicone sealing gaskets are installed at the points where the booster cylinder 4 contacts the brush cylinder 1 and the steel wire (at the clearance hole).

[0029] The redundant steps are executed periodically. When the redundant steps are completed, the wire-laying step is stopped, the brush cylinder 1 stops rotating, the booster cylinder 4 contacts the brush cylinder 1 and the steel wire and is sealed, and the acid enters the lower convex part 3 at the upper end through the booster cylinder 4. The acid entering the booster cylinder 4 per unit time is greater than the acid discharged from the lower convex part 3, and the pressure at the lower convex part 3 at the upper end is increased, and enters the brush cylinder 1 to flush the bristles 2, and is finally discharged from the lower convex part 3 at the lower end.

[0030] The implementation principle of this embodiment is: by using acid to clean the steel wire during the brushing process, the oxide layer can be removed more effectively.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
