Description

Technical Field

[0001] This utility model relates to a rotating body lubrication device for acid-free wire drawing, and belongs to the technical field of metal deep processing pre-coating equipment. Background Technology

[0002] When using online coating surface pretreatment process for prestressed spiral steel wire, water must be strictly prohibited from directly contacting the coating surface of the wire during rotation forming. A large amount of heat will be generated during the rotation forming process, which will affect the drawing speed.

[0003] The prestressed spiral steel wire adopts the following online pre-coating process: wire surface bending and peeling for rust removal – wire brush cleaning – high-pressure water rinsing – metal coating – drying – diameter reduction drawing – spiral forming – stabilization treatment – ​​water cooling – winding. The original manufacturer's rotating die box uses a water-resistant sleeve to cool the spiral die, and the wire surface lubrication relies solely on the residual drawing powder from the previous drawing stage for lubrication of the rotational forming stage. This method has several disadvantages: First, relying solely on the residual drawing powder from the previous drawing stage for lubrication of the wire surface during rotational forming is ineffective, causing a rapid increase in die temperature that damages the coating and necessitates a reduction in production speed. Second, cooling water still splashes out from the gap between the rotating body and the fixed outer shell, damaging the coating and affecting the lubrication effect. Therefore, a rotating body lubrication device for acid-free wire drawing is proposed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies or shortcomings in the existing technology by providing a rotating body lubrication device for acid-free wire drawing. By adding a wire drawing powder box in front of the rotating body mold, the surface of the drawn steel wire is pre-lubricated with powder. A mold is added at the powder box outlet to facilitate the adhesion of the wire drawing powder to the steel wire surface. A water-blocking ring is added to the rotating mold seat to prevent the mold cooling water from splashing onto the wire surface and damaging the coating layer. This greatly reduces the heat generated during the rotating wire drawing process, thereby increasing the drawing speed of the rotating wire drawing passes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a rotating mold box 1 and a mold box 3. The front end of the rotating mold box 1 is a wire drawing powder box 2. The mold box 3 is located inside the wire drawing powder box 2 and connected to the rotating mold box 1. The side of the rotating mold box 1 away from the wire drawing powder box 2 is connected to the rotating mechanism 6. A waterproof plate 4 is provided on the rotating mold box 1 near the rotating mechanism 6. A support plate 5 is provided in the middle of the rotating mold box 1.

[0006] Furthermore, the waterproof membrane 4 is provided with a conduit hole 4-1 in the middle, and an expansion groove 4-2 is provided below the conduit hole 4-1.

[0007] Furthermore, the support plate 5 has a wire groove 5-1 formed upwards.

[0008] Furthermore, the cross-section of the mold box 3 is circular, and a groove 3-1 is formed on the upper part of it.

[0009] Furthermore, the side of the rotating body mold box 1 connected to the rotating mechanism 6 is a fixed plate 1-1, and the fixed plate 1-1 is provided with a mounting groove 1-11 to cooperate with the rotating mechanism 6.

[0010] Furthermore, the contact end between the rotating body mold box 1 and the drawing powder box 2 is a mating plate 1-2, and a mating groove 1-21 is provided on the mating plate 1-2.

[0011] Furthermore, the powder box 2 has wire outlet grooves 2-1 at both ends, and the width of the wire outlet grooves 2-1 is smaller than the width of the wire grooves 3-1.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by adding a wire drawing powder box in front of the rotating die box, the surface of the drawn steel wire is pre-lubricated with powder again, and a mold is added at the powder box outlet, which is conducive to the wire drawing powder adhering to the surface of the steel wire. A water-blocking ring is added to the rotating die seat to prevent the mold cooling water from splashing onto the surface of the wire and damaging the coating layer, which greatly reduces the heat generated during the rotating forming and drawing process of the wire, thereby achieving the purpose of increasing the drawing speed of the rotating forming pass of the steel wire.

Detailed Implementation

[0022] See Figures 1-7 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a rotating mold box 1 and a mold box 3. The front end of the rotating mold box 1 is a wire drawing powder box 2. The mold box 3 is located inside the wire drawing powder box 2 and connected to the rotating mold box 1. Traditional rotating mold boxes use a water-proof sleeve to cool the spiral mold. The lubrication of the wire surface relies solely on the wire drawing powder remaining on the surface of the previous drawing to lubricate the rotating forming pass. However, the lubrication effect of the residual wire drawing powder is not good, and the mold heats up quickly, which will damage the coating. Therefore, in this embodiment, a wire drawing powder box is set up. During the production process, the surface of the drawn steel wire is pre-lubricated with powder in the wire drawing powder box, thereby improving the overall lubrication effect of the steel wire.

[0023] More specifically, the rotating mold box 1 is connected to the rotating mechanism 6 on the side away from the wire drawing powder box 2. A waterproof plate 4 is provided on the rotating mold box 1 near the rotating mechanism 6. The waterproof plate on the rotating mechanism side can effectively prevent the mold cooling water from splashing onto the wire surface, ensure that the coating is not wetted by the cooling water, improve the drawing lubrication effect on the wire surface, and thus greatly improve the drawing speed of the steel wire rotation forming pass.

[0024] A support plate 5 is provided in the middle of the rotating mold box 1. The support plate supports the steel wire to prevent it from sinking and ensures the overall flatness of the steel wire, thereby ensuring the powder addition effect.

[0025] More specifically, the waterproof membrane 4 has a conduit hole 4-1 in the middle, and an expansion groove 4-2 is provided below the conduit hole 4-1. The conduit hole is designed to better cooperate with the rotating mechanism, and the expansion groove can prevent deformation when the temperature is too high.

[0026] More specifically, the support plate 5 has an upward-facing wire groove 5-1, which works in conjunction with the steel wire to provide support and ensure the smooth rotation of the steel wire.

[0027] More specifically, the cross-section of the mold box 3 is circular, and a groove 3-1 is opened upwards, which is used for the placement and passage of steel wire.

[0028] More specifically, the side of the rotating body mold box 1 connected to the rotating mechanism 6 is a fixed plate 1-1. The fixed plate 1-1 is provided with an installation groove 1-11 that cooperates with the rotating mechanism 6. It can be understood that the middle of the installation groove is a hollow structure. The fixed part of the rotating mechanism is fixed through the installation groove, and the rotating wire part enters the hollow part and extends to the front end of the rotating body mold box.

[0029] More specifically, the contact end between the rotating mold box 1 and the wire drawing powder box 2 is a mating plate 1-2, and the mating plate 1-2 is provided with a mating groove 1-21. The mating groove cooperates with the wire drawing powder box to increase the support effect on the steel wire.

[0030] More specifically, the wire drawing powder box 2 has wire outlet grooves 2-1 at both ends. The width of the wire outlet groove 2-1 is smaller than the width of the wire groove 3-1. After the steel wire enters the wire drawing powder box, since the width of the wire outlet groove is greater than the width of the wire groove, the surrounding lubricating powder will exert a certain pressure on the surface of the steel wire during the powder addition process. This is beneficial for the wire drawing powder to adhere to the surface of the steel wire and improve the lubrication effect of the steel wire rotation forming.

[0031] The working principle of this utility model is as follows: The wire drawing powder box 2 is filled with lubricating powder. The steel wire enters the wire exit groove 2-1 and the wire groove 3-1 from the wire passage groove 5-1 and enters the wire drawing powder box 2, where it is submerged in lubricating powder. When the rotating mechanism 6 rotates, the surface of the drawn steel wire is lubricated again with powder. Since the width of the wire exit groove 2-1 is smaller than the width of the wire groove 3-1, a certain pressure is generated on the surface of the steel wire during the powder addition process, which is conducive to the adhesion of the wire drawing powder to the surface of the steel wire and improves the lubrication effect of the steel wire rotation forming. A waterproof plate 4 is set near the rotating mechanism 6 on the rotating mechanism 1, which can effectively prevent the mold cooling water from splashing onto the surface of the wire, ensuring that the coating is not wetted by the cooling water, improving the drawing lubrication effect of the wire surface, thereby greatly increasing the drawing speed of the steel wire rotation forming pass.

[0032] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
