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] In the process of steel wire production, various coatings are added to the steel wire due to different use conditions so that the steel wire can meet the use requirements. However, in the coating process, the oxide layer attached to the surface of the steel wire needs to be removed, and the existing removal method is not effective. Summary of the invention

[0003] In view of the shortcomings of the prior art, one of the purposes of the present 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 the present application is achieved through the following technical solutions:

[0005] A galvanized steel wire production process comprises the following steps: a wire unwinding step, unwinding the steel wire; a removal step, breaking the oxide layer on the surface of the steel wire; a pre-washing step, brushing the oxide layer on the surface of the steel wire and washing with acid at the same time; a pickling step, pickling the steel wire with acid; a water washing step, washing the steel wire with water; a wire drawing step, drawing the steel wire; a pickling step, pickling the steel wire; a water washing step, washing the steel wire with water; a coating step, coating the steel wire; a water washing step, washing the steel wire with water; a drying step, drying the steel wire; and a coiling step, 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 washed, and then pickled again, so that 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 both 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 removed well.

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

[0010] By adopting the above technical solution, the brush barrel is rotated to drive 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 arranged on the lower convex part, and the lower convex part forms a chamber for accommodating acid liquid.

[0012] By adopting the above technical solution, the existence of the lower protrusion for accommodating the acid liquid enables the steel wire to be immersed in the acid liquid both before and after contacting the bristles, thereby further enhancing the removal effect of 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 send out deformation, so that the acid is discharged.

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

[0016] By adopting the above technical solution, the existence 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 bristles arranged obliquely 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 to perform redundant settings on the steel wire.

[0020] By adopting the above technical solution, the existence of redundant steps makes it possible to redundantly store the steel wire, 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 liquid enters the lower protrusion at the upper end through the booster cylinder, and increases the pressure at the lower protrusion at the upper end, and enters the brush cylinder to rinse the bristles, and is finally discharged from the lower protrusion at the lower end.

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

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

[0026] The present application discloses a galvanized steel wire production process, comprising the following steps: a wire-unwinding step, in which the steel wire is unwound; a removal step, in which the oxide layer on the surface of the steel wire is broken by a shelling device; a pre-washing step, in which the oxide layer on the surface of the steel wire is brushed off and acid cleaning is performed at the same time; a redundant step, in which the steel wire is redundantly set, that is, the steel wire is pre-stored. 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 workstation for use in subsequent steps; a pickling step, in which the steel wire is pickled by acid; a water washing step, in which the steel wire is water washed; a wire drawing step, in which the steel wire is drawn; a pickling step, in which the steel wire is pickled; a water washing step, in which the steel wire is water washed; a coating step, in which the steel wire is coated; a water washing step, in which the steel wire is water washed; a drying step, in which the steel wire is dried; and a coiling step, in which the steel wire is coiled.

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

[0028] The brush cylinder 1 can also be detachably connected with a booster cylinder 4, which is connected to the outside world through a pipeline, and is sealed with the brush cylinder 1 and the steel wire. The booster cylinder 4 is used to increase the acid pressure at the lower convex part 3. The booster cylinder 4 is composed of two semicircular cylindrical structures (which can be spliced ​​manually or driven by actuators such as cylinders to move), and is provided with a clearance hole for the steel wire to pass through. The contact between the booster cylinder 4 and the brush cylinder 1 and the contact with the steel wire (the clearance hole) are both provided with rubber or silicone sealing pads.

[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 and seals the brush cylinder 1 and the steel wire, and the acid enters the lower protrusion 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 protrusion 3, and the pressure at the lower protrusion 3 at the upper end is increased, and the acid enters the brush cylinder 1 to rinse the bristles 2, and is finally discharged from the lower protrusion 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 protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
