Technical Field

[0001] This utility model relates to the field of phosphating treatment technology for metal workpieces, specifically a phosphating treatment device for the back surface of brake steel. Background Technology

[0002] Metal phosphating is a process that forms a phosphate conversion film through chemical and electrochemical reactions. The resulting phosphate conversion film is the phosphating film. The main purpose of phosphating brake steel backing is to provide protection for the brake steel backing, prevent corrosion to a certain extent, and serve as a primer before painting to improve the adhesion and corrosion resistance of the paint film. The current general process for phosphating brake steel backing is as follows: degreasing and derusting—pickling—surface conditioning and activation—phosphating—water washing—drying. After a certain period of use or number of uses, the phosphating solution needs to be replenished or replaced before reuse, otherwise it will affect the film quality. Frequent replenishment of the solution is time-consuming and labor-intensive, and the continuity and stability of the phosphating process are difficult to guarantee. Utility Model Content

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figures 1-8 As shown, a phosphate treatment device for brake steel back surface includes: a phosphate tank 1, a placement rack 101 disposed inside the phosphate tank 1, an equipment platform 2 installed on one side of the outer end of the phosphate tank 1, and an aeration assembly disposed inside the phosphate tank 1. The aeration assembly includes: a perforated pipe 3, a main air pipe 301, a perforated air distribution pipe hole 302, a branch air pipe 303, a blower 304, and an exhaust pipe 305.

[0027] The placement rack 101 has two support plates 102 installed inside. Multiple partitions 103 are fixedly installed on the top sides of the two support plates 102. When phosphate treatment is performed on the brake steel backing, the brake steel backing is placed in the placement rack 101. The support plates 102 provide support for placement, and the multiple partitions 103 can limit and clamp multiple brake steel backings in the placement rack 101 to prevent the brake steel backing from loosening and falling off. There are gaps between the multiple partitions 103. After the placement rack 101 is placed into the phosphate tank 1, the phosphate can flow between the multiple partitions 103 and contact the surface of the brake steel backing to perform phosphate treatment on the surface of the brake steel backing.

[0028] The placement frame 101 has support rods 104 fixedly installed on both sides of its top. The top of the support rods 104 is welded with lifting rings 105. After the brake steel back is placed and fixed on the placement frame 101, the placement frame 101 can be lifted by a hoisting device. That is, the hook on the hoisting device is hooked at the lifting ring 105, and the lifting ring 105 is subjected to force to lift the placement frame 101, which makes it easy to put the placement frame 101 into the phosphate bath 1. After the surface of the brake steel back is phosphated, it is also easy to lift the placement frame 101 out of the phosphate bath 1, which facilitates the loading and unloading of the brake steel back for phosphate processing.

[0029] The phosphating tank 1 has perforated pipes 3 at each of its four corners. One of the perforated pipes 3 has a main vent pipe 301 installed at its top. The main vent pipe 301 is made of rubber hose material. Multiple air distribution pipe holes 302 are opened on the outside of the four perforated pipes 3. Branch vent pipes 303 are installed between the four perforated pipes 3. The branch vent pipes 303 are connected to the air distribution pipe holes 302 by adhesive connectors. A blower 304 is fixedly installed on the top of the equipment platform 2 by bolts. An exhaust pipe 305 is installed inside the blower 304. The other end of the main vent pipe 301 is connected to the exhaust pipe 305.

[0030] When using the phosphating tank 1, the existing phosphating tank 1 is equipped with a heating device, which is common knowledge in the field. After pouring the phosphating solution into the phosphating tank 1, the phosphating solution can be heated to a higher temperature, so that the phosphating solution can perform phosphating treatment on the surface of the brake steel backing on the placement rack 101. During the phosphating treatment of the brake steel backing, the four perforated tubes 3 are driven to move down into the phosphating tank 1 at the same time and fit tightly against the four corners of the phosphating tank 1, so that the four perforated tubes 3 are immersed in the phosphating solution, making the liquid level of the phosphating solution higher than the four perforated tubes 3. At this time, the blower 304 is started to work, and the blower 304 generates negative pressure suction to draw in the solution. External air is blown into the exhaust pipe 305 and the main vent pipe 301 to increase airflow. The four perforated pipes 3 are connected through the branch vent pipes 303. Compressed air is added inside the four perforated pipes 3 and discharged into the phosphating tank 1 through the air distribution pipe hole 302. The compressed air is used to aerate and stir the phosphating solution in the phosphating tank 1, so as to achieve the purpose of stirring the chemical solution in the phosphating tank 1, making the chemical solution in the phosphating tank 1 fully mixed and heated evenly, thereby shortening the reaction time, increasing the reaction yield, extending the use time and number of times the phosphating solution can be used, and solving the problems of frequent replenishment and unstable phosphating treatment.

[0031] Among them, a lifting platform 4 is installed at the outer end of the phosphating tank 1. Lifting cylinders 401 are fixedly installed on both sides of the top of the lifting platform 4 by bolts. A telescopic rod 402 is connected to the top of the lifting cylinder 401. A lifting frame 403 is installed on the top of the telescopic rod 402. A connecting block 404 is installed between the two perforated pipes 3. The bottom side of the lifting frame 403 is fixedly installed with the connecting block 404 by bolts.

[0032] After the perforated tube 3 is used, the lifting cylinder 401 is activated to drive the telescopic rod 402 to move upward. The telescopic rod 402 pushes the lifting frame 403 to move the connecting block 404 and the perforated tube 3 upward. Since the connecting block 404 and the branch air pipe 303 are installed between the perforated tubes 3, the four perforated tubes 3 can be moved out of the phosphating tank 1 at the same time, so that the four perforated tubes 3 are placed on the top of the phosphating tank 1. The residual phosphating liquid in the perforated tubes 3 can be discharged from the air distribution pipe hole 302 and fall into the phosphating tank 1. When it is necessary to aerate and stir the phosphating liquid inside the phosphating tank 1, the perforated tubes 3 can be driven down into the phosphating tank 1 again, so as to avoid the perforated tubes 3 being soaked in the phosphating liquid for a long time and wasting it.

[0033] When the perforated tube 3 moves up and down, the main vent tube 301 is made of rubber hose material, which has good flexibility to avoid affecting the up and down movement of the perforated tube 3. In addition, the main vent tube 301 has sufficient movement length to prevent it from breaking after being pulled.

[0034] Among them, the top two sides of the lifting frame 403 are equipped with sliding sleeves 405, and the top two sides of the lifting platform 4 are equipped with positioning rods 406 that are slidably connected to the sliding sleeves 405. During the up and down movement of the lifting frame 403, the lifting frame 403 slides synchronously on the positioning rods 406 through the sliding sleeves 405, thereby positioning and moving the lifting frame 403 to ensure that after the four perforated tubes 3 move into the phosphating tank 1, they fit with the four corners inside the phosphating tank 1.

[0035] The bottom side of the phosphating tank 1 is equipped with a waste discharge pipe 5. The outer end of the waste discharge pipe 5 is threaded with a sealing cap 501. After the phosphating solution inside the phosphating tank 1 becomes ineffective, the sealing cap 501 at the outer end of the waste discharge pipe 5 is loosened and opened. The waste discharge pipe 5 can discharge the phosphating solution inside the phosphating tank 1 and clean the inside of the phosphating tank 1 before dropping new phosphating solution into the phosphating tank 1.

[0036] Working principle:

[0037] After the brake steel backing is fixed on the mounting frame 101, the mounting frame 101 can be lifted using a hoisting device. Specifically, the hook on the hoisting device is hooked onto the lifting ring 105, and the lifting ring 105 is subjected to force to lift the mounting frame 101, making it easy to place the mounting frame 101 into the phosphating tank 1. The existing phosphating tank 1 is equipped with a heating device, which is common knowledge in the field. After pouring phosphating solution into the phosphating tank 1, the phosphating solution can be heated to allow it to phosphate the surface of the brake steel backing on the mounting frame 101. During the phosphating process, four perforated tubes 3 are simultaneously driven down into the phosphating tank 1 and tightly fitted to the four corners inside the phosphating tank 1, immersing the four perforated tubes 3 in the phosphating solution. This ensures that the phosphating solution level is higher than the four perforated pipes 3. At this point, the blower 304 is started, generating negative pressure to draw in external air and blow air into the exhaust pipe 305 and main vent pipe 301 to increase airflow. The four perforated pipes 3 are connected through branch vent pipes 303, and compressed air is added inside the four perforated pipes 3. This compressed air is then discharged into the phosphating tank 1 through the air distribution pipe hole 302. The compressed air is used to aerate and agitate the phosphating solution in the phosphating tank 1, achieving the purpose of stirring the solution in the phosphating tank 1. This ensures that the solution in the phosphating tank 1 is fully mixed and heated evenly, thereby shortening the reaction time, increasing the reaction yield, extending the usage time and number of times the phosphating solution can be used, and solving the problems of frequent replenishment and unstable phosphating treatment.

[0038] After the perforated tube 3 is used, the lifting cylinder 401 is activated to drive the telescopic rod 402 to move upward. The telescopic rod 402 pushes the lifting frame 403 to move the connecting block 404 and the perforated tube 3 upward. Since the connecting block 404 and the branch air pipe 303 are installed between the perforated tubes 3, the four perforated tubes 3 can be moved out of the phosphating tank 1 at the same time, so that the four perforated tubes 3 are placed on the top of the phosphating tank 1. The residual phosphating liquid in the perforated tubes 3 can be discharged from the air distribution pipe hole 302 and fall into the phosphating tank 1. When it is necessary to aerate and stir the phosphating liquid inside the phosphating tank 1, the perforated tubes 3 can be driven down into the phosphating tank 1 again, so as to avoid the perforated tubes 3 being soaked in the phosphating liquid for a long time and wasting it.
