Description

Technical Field

[0001] The utility model relates to the technical field of steel wire surface treatment, in particular to a borax drying device for the steel wire surface. Background Art

[0002] The manufacturing process of steel wire is divided into rolling and drawing process, and the drawing process is further divided into dry drawing and wet drawing. When using the dry drawing process to produce steel wire products, it is generally necessary to use wire drawing powder for lubrication. However, wire drawing powder is relatively slippery and has poor adhesion performance, so it is difficult to adhere to the surface of the steel wire. Therefore, the borax coating process is generally used before wire drawing. After the aqueous borax solution dries, a rough surface is formed on the surface of the steel wire, so that the wire drawing powder can be brought into the wire drawing die, which plays a lubricating role during the drawing process, reduces die loss, reduces power loss, etc.

[0003] Borax is dissolved in hot water at 90°C. When the steel wire passes through the borax solution, the borax solution adheres to the surface of the steel wire. Use air blowing to partially blow off the borax solution on the surface of the steel wire and partially blow dry it, so that a uniform borax film is formed on the surface of the steel wire. The uniform thickness of the borax film meets the required standards, which is an important process control point of this process, so the blowing device determines the process effect of this process. If the wind pressure is too high, the surface will be blown very clean, or the air volume is too small, the surface is wet, or the surrounding wind speed and air volume are unbalanced, resulting in uneven borax adhesion on the surface of the steel wire, etc., which will lead to poor drawing effect in the drawing process, increased mold loss, poor surface quality of the steel wire and other defective products.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Example 1: Figure 1 , 2 As shown, the outer sleeve 1 is made of 316 stainless steel, with an internal inclination angle of 60°, and a G3 / 8 threaded hole a102 at the top for installing the air pipe joint, which is threadedly connected to the inner core 2. The mouthpiece 3 is made of cemented carbide powder metallurgy, with high hardness and good wear resistance. The fluororubber O-ring 7 is high temperature resistant and has a good sealing effect. The locking nut 6 is made of 316 stainless steel and is threadedly connected to the inner core 2. The inner core 2 is made of 316 stainless steel, and the front end is brazed with the alloy mouthpiece 3. The insulating support frame 4 is made of high-strength ABS plastic, which plays an insulating role and fixes the conductive ring 5.

[0037] like Figure 3 , 4 As shown, the outer diameter of the jacket 1 is 65mm, and there is a step with a diameter of 35mm and a length of 13mm at the front end. There is a cavity 101 with a diameter of 46mm inside, and the front angle S is 60°. The front end is a cylindrical hole 105 with a length A of 1 to 5mm and a diameter B. There is a sealing ring groove 107 with a width of 5mm and a depth of 2.5mm and a fine thread of M48*1.5 at the rear end. There is a plane with a width of 30mm at the top, and there is a G3 / 8 threaded hole a102 on the plane for installing the air pipe joint.

[0038] like Figure 5 , 6 As shown, the inner core 2 is made of 316 stainless steel, with a flange 201 of 6mm diameter and 5mm thickness at the rear end, an M32*1.5mm internal thread in the middle, a cylindrical cavity on the inside, and a tapered hole to the right, with a taper of 20°. The front end is a stepped hole 203 of 20mm diameter and 8mm depth, which is used to install the mouthpiece 3. The inner core 2 has an outer diameter of 30mm, a circular arc transition of 20mm radius at the front end, and an M48*1.5 fine-pitch external thread at the rear end, which is used to match the outer sleeve 1. There is a cylindrical surface with a diameter of 44.80mm and a width of 8mm at the front end of the thread, which is used to seal with the O-ring 7.

[0039] like Figure 7 As shown, the blowing nozzle 3 is made of cemented carbide, with an inner hole of 10 mm, an outer diameter of 20 mm, a width of 15 mm, a front end diameter of 10.8 mm, a cone angle of 60 degrees, and a chamfered corner of the inner hole at the rear end of R1 mm.

[0040] like Figures 8 to 10 As shown, the insulating support frame 4 is made of high-strength ABS plastic, which can play an insulating and supporting role. The part is a conical structure, with the materials on both sides removed from the conical surface, a 12mm diameter inner hole at the rear end, an m32*1.5 outer thread at the front end, and a 24mm inner hole diameter at the front end.

[0041] The specific working principle of the utility model is as follows:

[0042] like Fig.11 As shown, the drying device is installed at the outlet on the right side of the steel wire 8. The steel wire 8 with a diameter of 5.5 mm enters the borax tank 9 from the right side. The borax solution at a temperature of 95°C is sprayed on the surface of the steel wire 8 through the nozzle 10 through the circulating pump 11, and the steel wire 8 leaves the borax tank 9 to the left. The compressed air enters through the G3 / 8 threaded hole a102 on the outer jacket 1, and first enters the annular buffer cavity formed between the outer jacket 1 and the inner core 2 to stabilize the air flow rate and pressure. The compressed air blows toward the surface of the steel wire 8 along the circumferential gap between the outer jacket 1 and the inner core 2 at an angle of 60°, and meets at the outlet, i.e., the cylindrical hole 105, and blows to the right along the surface of the steel wire 8. By rotating the inner core 2, the size of the gap between the inner core 2 and the outer jacket 1 can be changed, and then locked by the locking nut 6, thereby changing the thickness of the borax layer remaining on the surface of the steel wire 8. If the steel wire 8 is not in the center position, the air blown to the surface of the steel wire 8 cannot be kept uniform, and the thickness of the borax layer is uneven. In order to avoid this situation from happening, a copper conductive ring 5 is installed at the right end of the insulating support frame 4. The conductive ring 5 is connected to a 5V voltage. When the eccentric distance of the steel wire 8 exceeds the allowable range, the 2.5V voltage of the conductive ring 5 will be grounded, and the equipment will alarm and adjust the position of the steel wire 8 to prevent the production of defective products.

[0043] In addition Fig.11 In the figure, the hollow arrows indicate the flow direction of the compressed air, and the solid arrows indicate the movement direction of the steel wire 8.

[0044] The above implementation is only to illustrate the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
