Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically to a high-speed small wire phosphating device. Background Technology

[0002] In the wire drawing process of stainless steel wire and other metal wires, the initial surface treatment of the wire involves pickling, phosphating, saponification, and drying. Due to the cumbersome process, the wire drawing speed is generally low. With the advent of high-speed (above 10m / s) wire drawing technology, its extremely high efficiency has led to the increasingly widespread application of high-speed wire drawing. However, with the increase in wire drawing speed, higher requirements are placed on wire lubrication and die precision. Otherwise, problems such as die jamming, wire breakage, and excessive die wear can easily occur. Especially when drawing small-diameter wires below 2mm, excessively high wire breakage frequency can seriously affect production efficiency and wire quality.

[0003] In existing technologies, phosphating treatment for 6.5mm and 8.5mm thick wires in low-speed environments typically employs a phosphating bath. The phosphating solution in the bath is heated to above 80°C, and the metal wire slowly passes through the solution. After a certain reaction time, a phosphating film forms on the surface of the metal wire. This results in a relatively thick phosphating film, which provides protection to the wire surface and also has a lubricating effect, offering some assistance during wire drawing. However, this phosphating method is unsuitable for processing small-diameter wires. The thick phosphating film can accumulate in the drawing die, causing die jamming, which is particularly detrimental to small wire dies. Furthermore, the low phosphating speed cannot be integrated into high-speed wire drawing production lines, making it unsuitable for high-speed fine wire drawing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a high-speed fine wire phosphating device that is suitable for the phosphating treatment of high-speed fine wires.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-speed small-wire phosphating device, comprising a phosphating tank and a phosphating wheel;

[0006] The phosphating tank has an inlet and an outlet at both ends, and the inlet and outlet are located on both sides of the phosphating tank.

[0007] The phosphating wheel is disposed in the phosphating tank, with its two ends rotatably connected to the inner walls of both sides of the phosphating tank, and its bottom located in the phosphating solution.

[0008] The wire enters the phosphating tank through the inlet and is wound onto the phosphating wheel. The phosphating tank contains heated phosphating solution. The wire wound on the phosphating wheel is phosphated in the phosphating solution as it passes the bottom of the phosphating wheel, and then exits the phosphating tank through the outlet to proceed to the next wire drawing process.

[0009] The beneficial effects of the above-mentioned high-speed small wire phosphating equipment are: the high-speed moving fine wire is wound on the phosphating wheel, which can enter the phosphating solution multiple times to ensure that there is enough time to complete the phosphating reaction, and can also control the time of each entry into the phosphating solution to avoid the formation of a thick phosphating film. Thus, it is possible to complete the phosphating of fine wires below 2mm in high-speed wire drawing production at 10m / s.

[0010] Furthermore, the phosphating wheel is provided with a spiral groove formed on its surface along the axial direction.

[0011] When there is only a single phosphating wheel, the wire is wound from one end of the phosphating wheel to the other end, and the spiral groove can guide it, so that the wire can enter the phosphating solution multiple times for short periods of time for phosphating treatment.

[0012] Furthermore, there are two phosphating wheels with the same height. One of the phosphating wheels has a smooth surface, while the other phosphating wheel has grooves circumferentially on its surface and multiple grooves distributed parallel to each other along the axial direction.

[0013] Two phosphating wheels can increase the number of phosphating cycles and the duration of phosphating, thus improving the phosphating effect. One phosphating wheel has grooves on its surface to limit the wire's movement, allowing it to be wound multiple times on the surface. The other phosphating wheel has a smooth surface, which allows the wire to have some turning space while tightening it.

[0014] Furthermore, it also includes a guide wheel assembly, comprising multiple guide wheels, which are rotatably disposed on the outer side of the phosphating tank having an outlet end, and are arranged sequentially up and down along the wire direction.

[0015] The guide wheel is used to guide the phosphated wire towards the wire drawing machine for the next wire drawing process.

[0016] Furthermore, it also includes a pressure roller assembly, comprising multiple pressure rollers, which are rotatably disposed on the outer side of the phosphating tank having an inlet end, and are arranged sequentially up and down along the wire direction.

[0017] Since the annealed wire is relatively hard, it can be wound around a wire pressing wheel to soften it and prevent subsequent wire skipping or breakage.

[0018] Furthermore, the top of the phosphating tank is provided with an openable and closable cover.

[0019] A cover plate is installed on the phosphating tank to form a sealing barrier, ensuring that the phosphating solution will not splash to the outside during the phosphating process.

[0020] Furthermore, an air duct is connected to the outlet of the phosphating tank, and the air duct is connected to a blower.

[0021] The phosphated wires are dried by blowing air through the duct.

[0022] Furthermore, the phosphating tank is equipped with a heating mechanism.

[0023] The heating mechanism is used to heat the phosphating solution.

[0024] Furthermore, it also includes a drive motor, which is located outside the phosphating tank and connected to the phosphating wheel.

[0025] The drive motor is used to drive the phosphating wheel to rotate.

[0026] Furthermore, it also includes a pressure assembly, comprising a lower pressure roller and a connecting rod, wherein the lower pressure roller is rotatably connected to the inner wall of the phosphating tank via the connecting rod and is located between two phosphating wheels.

[0027] By pressing the wire between the two phosphating rollers with the pressure roller, the wire can be self-tensioned and prevent violent shaking and wire skipping under high-speed movement. Attached Figure Description

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1 and Figure 2 This utility model provides a high-speed small wire phosphating device, including a phosphating tank 10 and a phosphating wheel 20. After the wire enters the phosphating tank 10, it is phosphated by winding it on the phosphating wheel 20.

[0039] Specifically, the phosphating tank 10 has an inlet 11 and an outlet 12 at both ends, through which wires can pass, and the inlet 11 and outlet 12 are located on both sides of the phosphating tank 10. The phosphating wheel 20 is disposed inside the phosphating tank 10, with both ends rotatably connected to the inner walls of both sides of the phosphating tank, and its bottom is located in the phosphating solution.

[0040] After the wire enters the phosphating tank 10 through the inlet 11, it is wound multiple times onto the phosphating wheel 20, from one end to the other, corresponding to the inlet 11 and outlet 12 respectively. The phosphating tank contains a heated phosphating solution. The wire wound on the phosphating wheel 20 undergoes a phosphating reaction as it passes the bottom of the wheel. Finally, it exits the phosphating tank 10 through the outlet 12 to proceed to the next drawing process. By winding the high-speed moving fine wire onto the phosphating wheel, it can enter the phosphating solution multiple times, ensuring sufficient time for the phosphating reaction to complete, while also controlling the time spent in the phosphating solution each time to prevent the formation of an excessively thick phosphating film.

[0041] Specifically, one or more phosphating wheels can be provided. In this embodiment, two phosphating wheels 20 are provided, and the two phosphating wheels are set at the same height. The surface of the phosphating wheel 20 near the wire inlet 11 is smooth, and the surface of the phosphating wheel 20 near the wire outlet 12 has circumferential grooves 21, and multiple grooves are distributed parallel to each other along the axial direction. Two phosphating wheels can increase the number of phosphating cycles and time, thereby improving the phosphating effect. The grooves on the surface of one phosphating wheel are used to limit the wire and can be wound multiple times on the surface. The surface of the other phosphating wheel is smooth, which can tighten the wire while allowing the wire some turning space. After the wire enters the phosphating tank, it first passes over the two phosphating wheels in sequence, then winds down from the grooves, then passes under the two phosphating wheels in sequence in the opposite direction, winds up from the smooth surface of the phosphating wheel and turns, and so on, winding multiple times in a repeated cycle.

[0042] Specifically, it also includes a guide wheel assembly and a wire pressing wheel assembly. The guide wheel assembly includes 3-5 guide wheels 30, all of which are rotatably arranged on the outer side of the end of the phosphating tank 10 with the wire outlet 12, and are arranged sequentially up and down along the wire direction. The guide wheels 30 are used to guide the phosphated wire to the direction of the wire drawing machine for the next wire drawing process.

[0043] The wire pressing wheel assembly includes 3-5 wire pressing wheels 31, all of which are rotatably arranged on the outer side of the phosphating tank 10 with the wire inlet 11, and are arranged sequentially up and down along the wire direction. Since the annealed wire is relatively hard, it can be wound around the wire pressing wheel 31 to soften the wire and prevent subsequent wire skipping or breakage.

[0044] Specifically, the top of the phosphating tank 10 is equipped with an openable and closable cover plate 40. When the cover plate 40 is closed, it forms a sealed barrier to ensure that the phosphating solution does not splash to the outside during the phosphating process. An air duct 50 is connected to the outlet 12 of the phosphating tank, and the air duct is connected to a blower. The blower dries the phosphated wire. A heating mechanism is provided inside the phosphating tank to heat the phosphating solution; in this embodiment, a heating pipe built into the tank wall is used for heating. A drive motor 60 is located on the outside of the phosphating tank 10 and is connected to the phosphating wheel 20. The drive motor 60 drives the phosphating wheel to rotate, thereby reducing friction with the wire.

[0045] Specifically, it also includes a wire pressing assembly, comprising a lower pressing roller 70 and a connecting rod 71. The lower pressing roller 70 is rotatably connected to the inner wall of the phosphating tank 10 via the connecting rod 71 and is located between two phosphating wheels. By pressing the wire between the two phosphating wheels with the lower pressing roller 70, the wire can be self-tensioned, preventing violent shaking and wire skipping under high-speed movement.

[0046] Example 2

[0047] This embodiment is basically the same as Embodiment 1, except that there is only one phosphating wheel, such as... Figure 3 As shown, when there is only one phosphating wheel 20, a spiral groove 22 is formed on the surface along the axial direction. Since there is only one phosphating wheel, the spiral groove 22 can play a guiding role, allowing the wire to be wound from one end of the phosphating wheel to the other end, thereby allowing the wire to enter the phosphating solution multiple times for phosphating reaction and avoiding excessively long immersion time.

[0048] The working principle of the above-mentioned high-speed small wire phosphating equipment is as follows: After the wire passes through the pressure rollers 31, it enters the phosphating tank 10 through the inlet 11 and is wound around the phosphating rollers 20 multiple times. The phosphating tank contains heated phosphating liquid. When the wire wound on the phosphating rollers 20 passes the bottom of the phosphating rollers, it can undergo phosphating reaction in the phosphating liquid. Finally, it exits the phosphating tank from the outlet 12, is dried by air blowing through the air duct 50, and is guided by the guide roller group to the next wire drawing process.

[0049] The high-speed wire phosphating equipment described above is suitable for high-speed drawing of fine wires, especially wires under 2mm in diameter at 10m / s. By winding the wire onto the phosphating wheel, it can be immersed in the phosphating solution multiple times to ensure sufficient time for the phosphating reaction to complete, while also controlling the time spent in the phosphating solution each time to avoid the formation of a thick phosphating film.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
