Description

Technical Field

[0001] This utility model relates to the technical field of steel wire processing, and in particular to a steel wire surface phosphating and pickling processing device. Background Technology

[0002] Steel wire is a type of steel product, a reprocessed product made from hot-rolled wire rod through cold drawing. After annealing, the steel wire needs to be pickled to remove oxides from the metal surface. Dilute acid is used during pickling to both corrode the oxides and prevent excessive damage to the metal substrate. Then, it undergoes phosphating to enhance the steel's corrosion resistance and adhesion to coatings. Pickling and phosphating are both essential steps in the steel wire production process.

[0003] The patent publication number is CN215209638 U discloses a steel wire pickling and phosphating treatment device, which includes a box, a partition 1 inside the box, a partition 2 inside the box, a pickling tank between the side of partition 1 away from partition 2 and the box, a phosphating tank between the side of partition 2 away from partition 1 and the box, and a water washing tank between partition 1 and partition 2. This utility model uses the cooperation of the water washing tank, a blower 1, a water tank, a blower pipe, a support rod, a water pipe, and a nozzle to rinse the pickled steel wire, avoiding the mixing of surface acid and phosphating solution, which would affect the quality of the phosphating solution. The blower 1 dries the water-washed steel wire, preventing the water on the steel wire surface from mixing with the phosphating solution and changing the concentration of the phosphating solution, thereby improving the quality of the phosphating solution and the phosphating treatment effect. However, the above equipment cannot perform certain pretreatment on the surface of the steel wire. Some dust or other impurities attached to the surface of the steel wire will reduce the subsequent pickling and phosphating effect of the steel wire, thus reducing the practicality and functionality of the device. Summary of the Invention

[0004] In order to improve the problem mentioned above that the existing equipment cannot perform certain pretreatment on the surface of the steel wire, and that the dust or other impurities attached to the surface of the steel wire will reduce the subsequent pickling and phosphating effect of the steel wire, thereby reducing the practicality and functionality of the device, this utility model provides a steel wire surface phosphating and pickling processing device.

[0005] This utility model provides a phosphating and pickling processing device for steel wire surfaces, which adopts the following technical solution:

[0006] A steel wire surface phosphating and pickling processing device includes a processing box, a box cover installed on the top of the processing box, a drying component arranged in the middle of the box cover, a plurality of partitions connected to the inner bottom wall of the processing box, the processing box being divided into a pickling tank, a first water washing tank, a drying tank, a phosphating tank and a second water washing tank by the plurality of partitions, a drain pipe connected to the bottom of the pickling tank, the first water washing tank, the phosphating tank and the second water washing tank, openings on both sides of the processing box, a guide component arranged inside the processing box, a rotating component arranged on the left side of the processing box, and a cleaning component arranged on the left side of the rotating component;

Slide plates are installed inside both sets of reserved slots, and a cleaning block is connected to the side of each slide plate near the center of the disc. A return spring is connected to the end of each slide plate away from the cleaning block.

[0008] By adopting the above technical solution, the worker first pulls up the box cover and removes it from the top of the processing box. Then, the worker pushes the cleaning block to move, which in turn moves the sliding plate and squeezes the return spring. Subsequently, the steel wire enters the processing box through the opening at the left end and, guided by the guide assembly, passes through the pickling tank, water washing tank one, drying tank, phosphating tank, and water washing tank two in sequence, finally exiting the processing box through the opening at the right end. During the steel wire's transmission, the two sets of cleaning blocks adhere tightly to the surface of the steel wire under the elastic force of the return spring, facilitating the pretreatment of impurities on the surface of the steel wire entering the processing box. At the same time, the rotating assembly drives the disc to rotate, which in turn drives the two sets of cleaning blocks to rotate along the outside of the steel wire, making the steel wire more thoroughly cleaned.

A transmission rod is fixedly connected to the bottom of each bevel gear, and the bottom of the transmission rod is fixedly connected to the top of the second rotating rod.

[0018] By adopting the above technical solution, when the drive motor is working, it drives the second rotating rod to rotate, the rotation of the second rotating rod drives the first bevel gear to rotate, the rotation of the first bevel gear drives the second bevel gear to rotate, and thus the second rotating rod can be driven to rotate through the transmission rod.

[0019] Optionally, the top of the processing box and the bottom of the box cover are provided with positioning components. The positioning components include two sets of positioning blocks, which are respectively installed at both ends of the bottom of the box cover. The top of the processing box is provided with positioning grooves that are inserted and cooperate with the positioning blocks at both ends.

[0021] Optionally, the rotating assembly includes two sets of connecting blocks, both sets of connecting blocks are installed on the side of the disc near the processing box, and a large gear is installed on the end of the two sets of connecting blocks away from the disc. A stepper motor is installed at the lower left end of the processing box, and a rotating shaft is installed at the power output end of the stepper motor. A small gear is sleeved on the outside of the rotating shaft, and the top of the small gear meshes with the bottom of the large gear. An installation groove is provided on the left side of the processing box, and both the large gear and the small gear are located inside the installation groove.

[0022] By adopting the above technical solution, when the stepper motor is working, it drives the small gear to rotate through the rotating shaft. The rotation of the small gear drives the large gear to rotate, and the rotation of the large gear drives the disc to rotate through the connecting block, which in turn drives the cleaning block to rotate, thus cleaning the surface of the steel wire more thoroughly.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] By using a combination of a disc, a pre-drilled slot, a cleaning block, a sliding plate, and a return spring, surface impurities can be pre-treated before the steel wire enters the processing box. At the same time, the rotating assembly can drive the disc and the cleaning block to rotate, so that the outer side of the steel wire can be cleaned evenly, thus improving the practicality of the device.

[0025] By coordinating the fan blades, transmission components, cross plate, rotating rod, heating tube, and drying chamber, the pickled steel wire can be dried with hot air, preventing the water on the surface of the steel wire from mixing with the phosphating solution and causing changes in the concentration of the phosphating solution, thereby improving the quality of the phosphating solution.

[0034] Please refer to the attached diagram in the instruction manual. Figure 1A drying assembly 13 is provided in the middle of the cover 12. The drying assembly 13 includes a drying chamber 1306. The drying chamber 1306 is fixedly installed in the middle of the cover 12. Several heating tubes 1305 are horizontally connected to the bottom of the inner cavity of the drying chamber 1306. A horizontal plate 1303 is installed inside the drying chamber 1306 near one end of the heating tubes 1305, and the horizontal plate 1303 is located above the heating tubes 1305. Several rotating rods 1304 are rotatably connected to the bottom of the horizontal plate 1303. Fan blades 1301 are fixedly installed at the bottom of each of the rotating rods 1304. A transmission component 1302 is provided between the rotating rods 1304 and the drying chamber 1306. When the heating element 1305 is activated, it heats the inside of the drying chamber 1306. When the transmission component 1302 is working, it drives the rotating rod 1304 to rotate. The rotation of the rotating rod 1304 drives the fan blade 1301 to rotate, thereby blowing hot air onto the surface of the steel wire to dry the steel wire.

[0035] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 A baffle 13061 is fixedly installed on the top of the drying chamber 1306. This baffle 13061 can block dust and debris. The transmission component 1302 includes a second rotating rod 13024, which is rotatably connected to the upper end of the inner cavity of the drying chamber 1306. A drive motor 13025 is fixedly installed on the right side of the drying chamber 1306, and the power output end of the drive motor 13025 is fixedly connected to the right end of the second rotating rod 13024. Several bevel gears 13021 are fixedly sleeved on the outer side of the second rotating rod 13024. The bottoms of the several bevel gears 13021 are all meshed with bevel gears 13023.

When the drive motor 13025 is working, it drives the second rotating rod 13024 to rotate. The rotation of the second rotating rod 13024 drives the first bevel gear 13021 to rotate. The rotation of the first bevel gear 13021 drives the second bevel gear 13023 to rotate, which in turn drives the first rotating rod 1304 to rotate through the transmission rod 13022.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 The bottom wall of the processing tank 2 is fixedly connected to several partitions 7, which divide the processing tank 2 into pickling tank 3, water washing tank 1 5, drying tank 6, phosphating tank 8, and water washing tank 2 9. Each of the pickling tank 3, water washing tank 1 5, phosphating tank 8, and water washing tank 2 9 is fixedly connected to a drain pipe 4, and a control valve 10 is installed on the drain pipe 4. This allows for easy opening or closing of the drain pipe 4 via the control valve 10.

[0037] Please refer to the attached diagram in the instruction manual. Figure 1The processing box 2 has openings 15 on both sides. Inside the processing box 2 is a guide assembly 11, which includes several first guide wheels 1101. These first guide wheels 1101 are rotatably connected to the interiors of the pickling tank 3, the first water washing tank 5, the phosphating tank 8, and the second water washing tank 9. Mounting brackets 1102 are fixedly installed on the side walls of both sides of the inner cavity of the processing box 2. Second guide wheels 1103 are rotatably connected between the mounting brackets 1102. Support brackets 1104 are fixedly installed on the tops of several partitions 7. Third guide wheels 1105 are rotatably connected between the support brackets 1104. This allows for the guidance of the steel wire to be processed, and subsequently enables the phosphating and pickling treatment of the steel wire surface.

[0038] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 4 A rotating assembly 16 is located on the left side of the processing box 2, and a cleaning assembly 14 is located on the left side of the rotating assembly 16. The cleaning assembly 14 includes a disc 1401. The top and bottom of the inner cavity of the disc 1401 are provided with reserved grooves 1402. Slide plates 1404 are slidably installed inside the two sets of reserved grooves 1402. A cleaning block 1403 is fixedly connected to the side of the two sets of slide plates 1404 near the center of the disc 1401. A return spring 1405 is fixedly connected to the end of the two sets of slide plates 1404 away from the cleaning block 1403.

[0039] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 The rotating assembly 16 includes two sets of connecting blocks 1601. Both sets of connecting blocks 1601 are fixedly installed on the side of the disc 1401 near the processing box 2. A large gear 1602 is rotatably installed on the end of the two sets of connecting blocks 1601 away from the disc 1401. A stepper motor 1604 is installed at the lower left side of the processing box 2. A rotating shaft 1605 is installed at the power output end of the stepper motor 1604. A small gear 1606 is fixedly sleeved on the outside of the rotating shaft 1605, and the top of the small gear 1606 meshes with the bottom of the large gear 1602. An installation groove 1603 is opened on the left side of the processing box 2. Both the large gear 1602 and the small gear 1606 are located inside the installation groove 1603. When the stepper motor 1604 is working, it drives the pinion 1606 to rotate through the shaft 1605. The rotation of the pinion 1606 drives the large gear 1602 to rotate. The rotation of the large gear 1602 drives the disc 1401 to rotate through the connecting block 1601, which in turn drives the cleaning block 1403 to rotate, thus cleaning the surface of the steel wire more thoroughly.

[0040] Working principle: In use, the operator first pulls up the lid 12, which moves the positioning block 101 upward, separating the positioning block 101 from the positioning groove 102. This allows the lid 12 to be removed from the top of the processing box 2. Then, the cleaning block 1403 is pushed to move, which pushes the sliding plate 1404 to move and squeezes the return spring 1405. Subsequently, the steel wire enters the processing box 2 through the opening 15 at the left end and, guided by the first guide wheel 1101, the second guide wheel 1103, and the third guide wheel 1105, passes through the pickling tank 3, the first water washing tank 5, the drying tank 6, the phosphating tank 8, and the second water washing tank 9 in sequence. Finally, it exits the processing box 2 through the opening 15 at the right end. Pickling solution is then added to the pickling tank 3, phosphating solution is added to the phosphating tank 8, and sufficient water is added to the first water washing tank 5 and the second water washing tank 9.

[0041] During the wire conveying process, the two sets of cleaning blocks 1403 are pressed tightly against the surface of the wire by the elastic force of the return spring 1405, which facilitates the pretreatment of impurities on the surface of the wire entering the processing box 2. At the same time, the stepper motor 1604 is started. When the stepper motor 1604 is working, it drives the pinion 1606 to rotate through the shaft 1605. The rotation of the pinion 1606 drives the large gear 1602 to rotate. The rotation of the large gear 1602 drives the disc 1401 to rotate through the connecting block 1601, which in turn drives the two sets of cleaning blocks 1403 to rotate along the outside of the wire, so that the wire is cleaned more thoroughly.

[0042] When the steel wire passes through pickling tank 3, its surface undergoes pickling. After passing through washing tank 5, the steel wire undergoes its first water wash. Finally, after passing through drying tank 6, the steel wire is dried. At this time, drive motor 13025 is started. When drive motor 13025 operates, it drives bevel gear 13021 to rotate via rotating rod 13024. The rotation of bevel gear 13021 drives bevel gear 13023 to rotate, which in turn drives transmission rod 13022 to rotate, which in turn drives the transmission rod 13024 to rotate... The fan blade 1301 rotates, and at the same time the heating tube 1305 is activated to heat the wire, thereby blowing hot air onto the surface of the wire to dry it. This prevents water and phosphating solution from mixing and reducing the concentration of the phosphating solution, thus improving the quality of the phosphating solution. After drying, the wire passes through the phosphating tank 8 for phosphating. When it passes through the second water washing tank 9, the wire undergoes a second water washing. After the device finishes working, the control valve 10 is opened to drain the liquid inside the pickling tank 3, the first water washing tank 5, the phosphating tank 8, and the second water washing tank 9 through the drain pipe 4.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
