Technical Field

[0001] The invention relates to the field of steel wire processing, in particular to a pickling and phosphating device for surface treatment of steel wire. Background Art

[0002] Steel wire is one of the steel varieties. It is a reprocessed product made from hot-rolled wire rods and cold-drawn. After annealing, the steel wire needs to be pickled to remove the oxides on the metal surface. The purpose of pickling with dilute acid is to corrode the oxides while ensuring that the metal matrix is ​​not excessively affected. Then it needs to be phosphated to enhance the corrosion resistance of steel and the bonding strength with the coating.

[0003] Before phosphating treatment, in order to ensure the effective cleaning of the steel wire surface during the pickling process, auxiliary cleaning is often performed with a cleaning brush to avoid the presence of firm stains on the steel wire surface. However, in order to avoid damage to the metal matrix of the steel wire, the cleaning force cannot be too large, and the problem of inadequate cleaning still exists.

[0004] Therefore, a new type of pickling and phosphating equipment for steel wire surface treatment is needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a pickling and phosphating equipment for steel wire surface treatment.

[0006] To achieve the above object, the present invention provides the following technical solutions: A pickling and phosphating device for surface treatment of steel wire comprises a pickling tank and a phosphating tank. A cleaning tank is connected between the pickling tank and the phosphating tank and at the end of the phosphating tank. The pickling tank comprises a tank body. A guide wheel for the steel wire to pass through is arranged along the inside of the tank body. A cleaning brush driven by a driving motor is provided on one side of the guide wheel. The steel wire passes through four directions of bending in sequence at obtuse angles along the top, bottom, left and right directions between each group of guide wheels and the cleaning brush.

[0007] As a further solution of the present invention: the pickling tank also includes a feed chuck, which consists of a sleeve and a jacket. The sleeve is a C-shaped tube structure with an opening facing upward, which is clamped and fixed at one end of the tank body, and an O-type jacket with a top breakpoint opening is nested inside.

[0008] As a further solution of the present invention: an arc-shaped guide groove is provided between each group of guide wheels and the cleaning brush and is connected to the pool body, and a steel wire is passed through the guide groove and enters between the guide wheel and the cleaning brush.

[0009] As a further solution of the present invention: both ends of the guide groove are arranged along the tangent direction of the front and rear guide wheels.

[0010] As a further solution of the present invention: the guide groove is composed of a guide tube and a limiting tube. The limiting tube is arranged at the front end of the guide wheel. A semicircular guide tube is fixedly sleeved on the outside of the limiting tube. The inner wall of the guide tube is opposite to the tangent direction of the front end guide wheel.

[0011] As a further solution of the present invention: the end faces of the limiting tubes are all concave cone-mouth structures.

[0012] As a further solution of the present invention: the cleaning brush is rotatably arranged on the guide groove, and a transparent window is opened at a corresponding position of the guide groove for the cleaning brush structure to pass through.

[0013] As a further solution of the present invention: three groups of guide wheels, two high and one low, are arranged in the cleaning pool, wherein a cleaning nozzle is arranged along the tangent direction from the low guide wheel to the tail guide wheel and across the cleaning pool.

[0014] As a further solution of the present invention: the cleaning nozzle includes a water pipe and a spray chuck. The water pipe is arranged across the cleaning pool. An inverted C-shaped spray chuck is installed on the water pipe. A steel wire passes through the spray chuck.

[0015] 1. In the pool body of the present invention, guide wheels for the steel wire to pass through are arranged along the line, and a cleaning brush driven by a driving motor is provided on one side of the guide wheel. The steel wire is bent and passed in four directions in sequence at obtuse angles along the top, bottom, left and right sides between each group of guide wheels and the cleaning brush. By arranging a cleaning brush at the position where the guide wheel guides the steel wire, the guide wheel guides the steel wire to bend and deform, resulting in separation of surface dirt from the steel wire structure, and cleaning with the cleaning brush, thereby ensuring its cleaning ability for dirt, thereby improving the pickling effect, and finally ensuring the phosphating effect.

[0016] 2. In the present invention, there is an arc-shaped guide groove between each group of guide wheels and the cleaning brush connected to the pool body. The steel wire is passed through the guide groove and enters between the guide wheel and the cleaning brush. The steel wire is guided by the guide groove, which reduces the difficulty of passing the steel wire between the various structures in the pool body.

[0028] The present embodiment provides a pickling and phosphating device for surface treatment of steel wire, 1 comprising a pickling tank 1 and a phosphating tank 3, a cleaning tank 2 is connected between the pickling tank 1 and the phosphating tank 3 and at the end of the phosphating tank 3, the pickling tank 1 comprises a tank body 16, a guide wheel 13 for the steel wire to pass through is arranged along the tank body 16, a cleaning brush 14 driven by a driving motor 15 is provided on one side of the guide wheel 13, and the steel wire passes through in four directions in sequence along the top, bottom, left and right at an obtuse angle between each group of guide wheels 13 and the cleaning brush 14; By equipping the guide wheel 13 with a cleaning brush 14 at the position where the steel wire is guided, the guide wheel 13 guides and bends the steel wire, causing the surface dirt to be separated from the steel wire structure and the cleaning brush 14 to clean it, thereby ensuring its ability to clean dirt, thereby improving the pickling effect and finally ensuring the phosphating effect.

[0029] The pickling tank 1 further comprises a feed chuck 11, which is composed of a sleeve 111 and a jacket 112. The sleeve 111 is a C-shaped tube structure with an opening facing upward, which is clamped and fixed at one end of the tank body 16, and an O-shaped jacket 112 with a top breakpoint opening is nested inside. The feeding chuck 11 with a top opening is used to quickly clamp and fix the feeding steel wire, ensuring that the steel wire material entering the pickling tank 1 is stable and does not shake.

[0030] Among them, there is an arc-shaped guide groove 12 connected to the pool body 16 between each group of guide wheels 13 and the cleaning brush 14. The steel wire is passed through the guide groove 12 and enters between the guide wheels 13 and the cleaning brush 14. The steel wire is guided by the guide groove 12, thereby reducing the difficulty of passing the steel wire between the various structures in the pool body 16.

[0031] Furthermore, both ends of the guide groove 12 are arranged along the tangent direction of the front and rear guide wheels 13, thereby ensuring that the overall curvature of the steel wire changes evenly during the guidance of the guide groove 12, thereby avoiding bending or jamming of the steel wire.

[0032] Furthermore, the guide groove 12 is composed of a guide tube 121 and a limit tube 122. The limit tube 122 is arranged at the front end of the guide wheel 13. The outer side of the limit tube 122 is fixedly sleeved with a semicircular guide tube 121. The inner wall of the guide tube 121 is opposite to the tangent direction of the front guide wheel 13. The steel wire is limited by the limiting tube 122 to improve the accuracy when passing through the guide wheel 13 and the cleaning brush 14, while the remaining positions are guided by the semi-open guide tube 121, which increases the contact between the steel wire and the acid liquid outside the guide groove 12 while completing the guiding function, thereby improving the cleaning effect.

[0033] Furthermore, the end faces of the limiting tube 122 are all concave cone structures, thereby reducing the resistance of the steel wire when passing through the end face position of the limiting tube 122, avoiding jamming or scratching.

[0034] Furthermore, the cleaning brush 14 is rotatably arranged on the guide groove 12, and a transparent window is opened at a corresponding position on the guide groove 12 for the cleaning brush 14 structure to pass through, so as to provide support for the cleaning brush 14 at the position other than the two sides contacting the pool body 16, thereby improving its running stability.

[0035] Among them, three groups of guide wheels 13, two high and one low, are arranged in the cleaning pool 2. A cleaning nozzle 21 is arranged along the tangent direction from the low-position guide wheel 13 to the tail-end guide wheel 13 and spans the cleaning pool 2. The three groups of guide wheels 13 guide the steel wire in a triangular path, and the cleaning nozzle 21 sprays on its ascending path, so that the waste liquid after flushing automatically drips along the steel wire to the bottom of the cleaning pool 2, thereby reducing the acid liquid entering the phosphating pool 3 and affecting the composition of the phosphating pool 3.

[0036] Specifically, the cleaning nozzle 21 includes a water pipe 211 and a spray chuck 212. The water pipe 211 is arranged across the cleaning pool 2. An inverted C-shaped spray chuck 212 is installed on the water pipe 211. The steel wire passes through the spray chuck 212. The top of the spray chuck 212 has a through hole connected to the liquid path in the water pipe 211. The steel wire is covered at all angles by the C-shaped spray chuck 212 to avoid spray dead angles and achieve comprehensive spray flushing and cleaning. At the same time, the spray chuck 212 structure can also scrape the water liquid to reduce the amount of water brought into the phosphating pool 3.

[0037] When implementing the technical solution of this embodiment, the steel wire is inserted into the top opening of the feed chuck 11 of the pickling tank 1, and then the steel wire is bent and passed in four directions along the guide groove 12 and between each group of guide wheels 13 and the cleaning brush 14 at an obtuse angle along the up, down, left and right directions respectively, and then it is passed through the cleaning tank 2, the phosphating tank 3, and the guide wheel 13 group in the cleaning tank 2 in turn. After starting the equipment, the steel wire moves under the action of the unwinding and winding equipment. When passing through the position of the guide wheel 13 and the cleaning brush 14, the guide wheel 13 guides and bends the steel wire to deform, resulting in the separation of surface dirt and the steel wire structure, and the cleaning brush 14 is used to clean the steel wire, thereby ensuring its ability to clean dirt, thereby improving the pickling effect, and finally ensuring the phosphating effect.
