Description

Technical Field

[0001] The utility model relates to the technical field of pickling and phosphating, and particularly relates to a pickling and phosphating device for cold-drawn steel sections. Background Art

[0002] Pickling and phosphating is a process for metal surface treatment. Metal is cleaned with acid of a certain concentration to remove rust on the surface, and phosphating is to soak the metal with a phosphating solution to form an oxide film on the surface, which can prevent rust and improve the adhesion of paint, preparing for the next process. Cold-drawn steel sections generally use pickling and phosphating equipment for pickling treatment during production. After pickling, the metal surface is silver-white, improving the corrosion resistance of cold-drawn steel sections.

[0003] The pickling and phosphating equipment mainly consists of parts such as pickling and phosphating tanks. During pickling and phosphating, a lot of large-particle pickling and phosphating impurities will be generated. To prevent these impurities from adhering to the surface of cold-drawn steel sections, in the prior art, such as the pickling and phosphating equipment for cold-drawn steel sections disclosed in the publication number CN219508030U, a filter frame is used to soak and filter impurities. Although most of the impurities can be filtered, when the cold-drawn steel section is lifted, large particles of impurities still exist on the upper surface, making it difficult to manually remove them and resulting in poor pickling and phosphating effects. Therefore, we propose a pickling and phosphating equipment for cold-drawn steel sections. Summary of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide a pickling and phosphating equipment for cold-drawn steel sections, which includes a pickling and phosphating tank. Connecting platforms are installed on both sides of the pickling and phosphating tank. A movable first C-shaped frame is installed on the connecting platform. A cylinder is installed on the first C-shaped frame. The output end of the cylinder is connected with a filter frame through a connecting plate. The filter frame is used to place cold-drawn steel sections for pickling and phosphating. A second C-shaped frame is movably installed on the pickling and phosphating tank. A movable spray head is provided on the second C-shaped frame. The spray head sprays pickling and phosphating solution on the pickled and phosphated cold-drawn steel sections to remove surface impurities.

[0005] Preferably, a driving motor is fixed on the outer side of the second C-shaped frame. The output end of the driving motor is fixed with a bidirectional lead screw. A rectangular block is threadedly connected to the bidirectional lead screw. The spray head is fixedly installed on the upper surface of the rectangular block. A guiding slide rail is fixed inside the second C-shaped frame. The rectangular block is slidably connected to the guiding slide rail through a guiding slider.

[0006] Preferably, a pump is installed on the connecting platform. The input end of the pump is communicated with a suction pipe extending into the pickling and phosphating tank, and its output end is communicated with a delivery pipe connected to the spray head.

[0007] Preferably, first electric push rods are installed on both sides of the upper edge of the pickling and phosphating tank. The output ends of the first electric push rods are hinged and slidably installed with the second C-shaped frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-4As shown in the figure, a pickling and phosphating device for cold-drawn steel profiles includes a pickling and phosphating tank 1. Connecting platforms 2 are installed on both sides of the pickling and phosphating tank 1. A movable first C-shaped frame 3 is installed on the connecting platform 2. A cylinder 4 is installed on the first C-shaped frame 3. The output end of the cylinder 4 is connected with a filter frame 5 through a connecting plate. The filter frame 5 is used to place cold-drawn steel profiles for pickling and phosphating. A second C-shaped frame 6 is movably installed on the pickling and phosphating tank 1. A movable spray head 7 is provided on the second C-shaped frame 6. The spray head 7 sprays pickling and phosphating solution on the pickled and phosphated cold-drawn steel profiles to remove surface impurities. A driving motor 8 is fixed on the outer side of the second C-shaped frame 6. The output end of the driving motor 8 is fixed with a bidirectional lead screw 9. A rectangular block 10 is threadedly connected to the bidirectional lead screw 9. The spray head 7 is fixedly installed on the upper surface of the rectangular block 10. A guiding slide rail 11 is fixed inside the second C-shaped frame 6. The rectangular block 10 is slidably connected to the guiding slide rail 11 through a guiding slider 12. A pump 13 is installed on the connecting platform 2. The input end of the pump 13 is communicated with a suction pipe 14 extending into the pickling and phosphating tank 1, and its output end is communicated with a delivery pipe 15 connected to the spray head 7.

[0019] When pickling and phosphating cold-drawn steel profiles, the cold-drawn steel profiles are placed into the filter frame 5, and the cylinder 4 is used to push and convey the filter frame 5 into the pickling and phosphating tank 1 for pickling and phosphating. After pickling and phosphating, the cold-drawn steel profiles are driven by the cylinder 4 to extend out of the pickling and phosphating tank 1. First, the filter frame 5 filters to prevent the cold-drawn steel profiles from adhering to more impurities in the pickling and phosphating solution. However, when extending out, a small amount of impurities will still adhere to the upper surface of the cold-drawn steel profiles. At this time, the pump 13 is started to extract the pickling and phosphating solution in the pickling and phosphating tank 1 through the suction pipe 14. A filter screen cover is arranged at the extraction end of the suction pipe 14 to prevent any impurities from being extracted. The extracted pickling and phosphating solution is used to wash the impurities adhering to the surface of the cold-drawn steel profiles through the delivery pipe 15 and the spray head 7, so as to completely remove the impurities, improve the pickling and phosphating efficiency, and at the same time, the driving motor 8 is started synchronously to drive the bidirectional lead screw 9 to rotate. Under the limiting action of the guiding slide rail 11 and the guiding slider 12 on the rectangular block 10, the bidirectional lead screw 9 drives the rectangular block 10 to reciprocate, thereby driving the spray head 7 to reciprocate to wash各处 on the surface of the cold-drawn steel profiles, improving the comprehensiveness and cleanliness of the cleaning.

[0020] First electric push rods 16 are installed on both sides of the upper edge of the pickling and phosphating tank 1. The output ends of the first electric push rods 16 are hinged and slidably installed with the second C-shaped frame 6.

[0021] By setting the first electric push rods 16, the second C-shaped frame 6 can be pushed to be inclined at a certain angle by synchronously controlling the first electric push rods 16, thereby driving the spray head 7 thereon to be inclined. By the inclination of the spray head 7, the spraying range for the cold-drawn steel profiles can be expanded, further improving the comprehensiveness of the cleaning.

[0022] Sliding grooves 17 are respectively formed in the connecting platforms 2, sliders 18 are slidably mounted in the sliding grooves 17, the bottom of the first C-shaped frame 3 is connected to the sliders 18, and second electric push rods 19 are respectively installed in the sliding grooves 17. The output ends of the second electric push rods 19 are connected to the sliders 18.

[0023] After the cold-drawn steel is cleaned, by controlling the synchronous operation of the two second electric push rods 19, the first C-shaped frame 3 is driven to move by pushing the sliders 18 to move, so that the cold-drawn steel in the filter box 5 gradually moves away from the pickling and phosphating pool 1, and then it can be taken out.
