Description

Technical Field

[0001] This utility model relates to the field of pickling technology, specifically to a high-efficiency and uniform pickling mechanism for a disc-shaped surface. Background Technology

[0002] Pickling of coiled steel is a metal surface treatment process mainly used to remove impurities such as oxide scale, rust, and oil stains from the surface of coiled steel to improve its surface quality and subsequent processing performance. Cold-drawn bright round steel, also known as cold-drawn bright round steel, refers to round steel produced by cold drawing. This type of product has good electroplating performance, can replace copper products, and greatly reduces product costs. Its cutting and processing are very easy, so the processing efficiency can be greatly improved compared to ordinary steel, making processing easier. During the processing of bright round steel, it is necessary to pickle it to remove oxide scale and rust from the steel surface. The principle of sulfuric acid pickling is to use sulfuric acid to react with iron oxides to generate water-soluble ferrous sulfate and ferric sulfate, thereby removing oxide scale.

[0017] By adopting the above technical solution, the blade design increases the contact area with the solution, and the rotation generates eddies to accelerate the chemical reaction between the pickling solution and the disc surface, thereby increasing the pickling speed.

The cylindrical sealing plate fits tightly with the processing groove to prevent pickling solution leakage. The spherical and conical protrusions on the pusher slider push the coiled material in a point contact manner, avoiding scratching the surface and ensuring product quality while improving operational safety.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency and uniform pickling mechanism for a disc-shaped surface, comprising a bottom support 1, a processing shell 2, an inlet pipe 3, an outlet pipe 4, an electric push rod 5, a support baffle 6, an upper limit plate 7, a sealing plate 8, a cylinder body 9, a linkage slider 10, a pushing slider 11, a drive motor 12, a transmission gear 13, a linkage rotating block 14, and a stirring cylinder 15. The bottom support 1 has the processing shell 2 fixedly connected to its upper surface. The inlet pipe 3 and the outlet pipe 4 are respectively installed through the two sides of the processing shell 2. The upper surface of the processing shell 2... The processing housing 2 is equipped with processing grooves, and the bottoms of the processing grooves are interconnected. The inlet pipe 3 and outlet pipe 4 are respectively connected to the processing grooves on both sides of the processing housing 2. Sulfuric acid solution is injected into the processing grooves on the upper surface of the processing housing 2 through the inlet pipe 3. Since the bottoms of the processing grooves of the processing housing 2 are interconnected, the solution can be evenly distributed to each groove. The electric push rod 5 is activated, and its output end pushes the support baffle 6 down, which drives the upper limit plate 7 and the sealing plate 8 to press down, confining the coiled material in the processing groove. The sealing plate 8 is sealed with the groove to prevent solution leakage.

[0022] Electric push rods 5 are fixedly connected to the upper surfaces of both ends of the bottom bracket 1. Support baffles 6 are fixedly connected to the output ends of the two electric push rods 5. Upper limit plates 7 are fixedly connected to the lower ends of the support baffles 6. Sealing plates 8 are fixedly connected to the lower surface of the upper limit plates 7. A cylinder body 9 is fixedly connected to the lower surface of the bottom bracket 1. The upper limit plates 7 are disc-shaped, and the sealing plates 8 are cylindrical. The sealing plates 8 are correspondingly positioned to the machining grooves of the machining housing 2. The output end of the cylinder body 9 penetrates the bottom surfaces of the bottom bracket 1 and the machining housing 2. The output end of the cylinder body 9 is fixedly connected to the lower surface of the linkage slider 10. Block 10 is slidably connected to the processing shell 2. The pusher slider 11 passes through the bottom surface of the processing groove of the processing shell 2. The upper surface of the pusher slider 11 is provided with a spherical conical protrusion. When the drive motor 12 is started, its output shaft drives the transmission gear 13 on one side to rotate. Through the linkage block 14, multiple transmission gears 13 rotate synchronously. The transmission gear 13 drives the stirring cylinder 15 to rotate through the rotating shaft. Its lower blades form a vortex in the solution, uniformly stirring the pickling solution and accelerating the chemical reaction with the oxide scale on the disc surface. The stirring cylinder 15 is rotatably connected to the sealing plate 8 to avoid affecting the rotational flexibility due to the fixed sealing plate 8.

[0023] The processing shell 2 has an internal cavity, and a linkage slider 10 is provided on the inner wall of the cavity. A pusher slider 11 is fixedly connected to the upper surface of the linkage slider 10. The stirring mechanism includes a drive motor 12, which is fixedly connected to the upper end of the upper limit plate 7. A transmission gear 13 is installed on the upper surface of the upper limit plate 7, and a linkage rotating block 14 is provided on the upper surface of the upper limit plate 7. A stirring cylinder 15 is installed through the lower surface of the sealing plate 8. The output end of the cylinder body 9 pushes the linkage slider 10 upward, causing it to slide on the inner wall of the processing shell 2, which drives the pusher slider 11 to rise and insert into the bottom of the processing groove of the processing shell 2. The spherical conical protrusion on the upper surface of the pusher slider 11 pushes the disc in a point contact manner, causing it to move slowly in the processing groove of the processing shell 2, ensuring that the surface fully contacts the flowing pickling solution and achieving uniform pickling. The linkage slider 10 is slidably connected to the processing shell 2 to ensure a smooth pushing process.

[0024] A stirring mechanism is provided between the upper limit plate 7 and the sealing plate 8. The mechanism drives a transmission gear 13 on one side via a drive motor 12, which then drives the remaining transmission gear 13 and the stirring cylinder 15 to rotate via a linkage block 14, thereby stirring the solution. The transmission gear 13 is rotatably connected to the upper limit plate 7, and the transmission gear 13, sealing plate 8, and stirring cylinder 15 are correspondingly arranged. The output end of the drive motor 12 is fixedly connected to the shaft of the transmission gear 13 on one side. Blades are provided on the lower outer surface of the stirring cylinder 15. The upper end of the rotating shaft of the stirring cylinder 15 passes through the upper surface of the upper limit plate 7 and is fixedly connected to the rotating shaft of the transmission gear 13. After pickling, the waste pickling liquid is discharged through the liquid outlet pipe 4. The bottom of the processing groove is connected to ensure that the waste liquid is completely drained. The electric push rod 5 is started in reverse, which drives the upper limit plate 7 and the sealing plate 8 to rise, release the limit on the disc, the cylinder body 9 retracts, and the pusher slider 11 descends to facilitate the removal of the processed disc, thus completing the entire pickling process.

[0025] Working principle: When using this high-efficiency and uniform pickling mechanism for the disc surface, the pickling solution is injected into the processing groove connected to the processing shell 2 through the inlet pipe 3. The electric push rod 5 drives the support baffle 6, which in turn drives the upper limit plate 7 and the sealing plate 8 to press down and fix the disc. The sealing plate 8 seals with the groove. The drive motor 12 drives the transmission gear 13, which, through the linkage rotating block 14, causes the stirring cylinder 15 to rotate. The blades stir the solution and accelerate the reaction. After pickling is completed, the waste liquid is discharged from the outlet pipe 4. The electric push rod 5 and the cylinder body 9 are reset, and the disc is taken out, which increases the overall practicality.
