Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing steel pipe processing technology, and in particular to a pickling and drying device for bearing steel pipe processing. Background Technology
[0002] Bearing steel pipe refers to hot-rolled or cold-rolled (cold-drawn) seamless steel pipe used to manufacture ordinary rolling bearing rings. In order to prevent the surface of bearing steel pipe from rusting, pickling is used to remove the oxide scale or burrs on the metal surface and to check for defects on the metal surface.
[0003] According to CN207918963U, a pickling device for processing bearing steel pipes includes a housing containing, from left to right, a pickling tank, a clear water tank, a neutralization tank, and an alcohol tank. The device involves pickling and rust removal using a rotating container within the pickling tank, followed by thorough cleaning in the clear water, neutralization, and alcohol tanks, and then drying under the action of a fan. In the aforementioned document, multiple bearing steel pipes are moved using material bags. However, the accumulation of a large number of bearing steel pipes makes it difficult for the surface of some pipes to come into contact with the pickling solution. Furthermore, the fan can only dry the surface of the bearing steel pipes, preventing the inner rings from contacting the drying airflow, thus affecting subsequent processing. Utility Model Content
[0004] The purpose of this invention is to solve the problem of incomplete pickling of bearing steel pipes in the prior art, and to propose a pickling and drying device for processing bearing steel pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pickling and drying apparatus for processing bearing steel pipes includes a processing box for pickling bearing steel pipes, and a drying nozzle for drying bearing steel pipes on the processing box. Symmetrically arranged telescopic rods are fixedly installed on the processing box, and the output ends of the two telescopic rods are integrally connected to a bracket. Rotary shafts that are evenly distributed and connected to the bracket are rotatably installed, and an installation structure for installing bearing steel pipes is integrally connected to the rotating shafts.
[0007] Preferably, the bracket is horizontally positioned above the processing box, and the rotating shaft is correspondingly vertically positioned.
[0008] Preferably, the installation structure includes a storage bag for surrounding the bearing steel pipe, an installation plate is fixedly installed on the rotating shaft, and symmetrically arranged positioning columns are fixedly installed on the installation plate. The upper end of the storage bag is provided with a connecting ear that cooperates with the positioning column. The drying nozzle consists of nozzle one and nozzle two.
[0009] Preferably, the mounting plate and the rotating shaft extend to the lower end of the bracket, and the storage bag has an annular hollow structure with an opening at the top.

[0011] Preferably, a motor connected to a rotating shaft is fixedly mounted on the bracket, and a gear for transmission is fixedly mounted on the rotating shaft.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. This utility model sets multiple evenly distributed rotating shafts on the bracket, so that the storage bag below the rotating shaft can independently store the bearing steel pipe, thereby increasing the contact degree between the bearing steel pipe and the pickling solution during pickling.
[0014] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3A pickling and drying apparatus for processing bearing steel pipes includes a processing box 1 for pickling bearing steel pipes, and a drying nozzle for drying bearing steel pipes is provided on the processing box 1.
[0021] The processing box 1 is fixedly installed with symmetrically arranged telescopic rods 2, and the output ends of the two telescopic rods 2 are integrally connected to the brackets 3. The brackets 3 are rotatably installed with evenly distributed and transmission-connected rotating shafts 4. The extension and retraction of the output ends of the telescopic rods 2 can drive the brackets 3 to move up or down. During the process of moving up or down, the brackets 3 can adjust the height of the bearing steel pipe.
[0022] The bracket 3 is horizontally positioned above the processing box 1, and the rotating shaft 4 is vertically positioned correspondingly. A motor connected to the rotating shaft 4 is fixedly mounted on the bracket 3, and a gear for transmission is fixedly mounted on the rotating shaft 4, according to the instruction manual. Figure 1 As shown, after the motor is powered on, it drives one of the rotating shafts 4 to rotate. By setting a gear for transmission connection on the rotating shaft 4, multiple bearing steel pipes can rotate during pickling or drying. This not only increases the contact between the pickling solution and the bearing steel pipes, but also enables the surface of the bearing steel pipes to be thoroughly dried. In addition, the rotating shaft 4 is integrally connected to an installation structure for installing the bearing steel pipes.
[0023] The mounting structure includes a storage bag 6 for surrounding the bearing steel tube, a mounting plate 5 fixedly mounted on the rotating shaft 4, and symmetrically arranged positioning posts 7 fixedly mounted on the mounting plate 5. The upper end of the storage bag 6 is provided with a connecting ear that mates with the positioning post 7. The mounting plate 5 and the rotating shaft 4 extend to the lower end of the bracket 3. The storage bag 6 is a ring-shaped hollow structure with an open top. The drying nozzle consists of a first nozzle 9 and a second nozzle 11. The storage bag 6 can be installed by the interaction of the positioning post 7 and the mounting hole on the connecting ear, so that the bearing steel tube is in a vertical state after installation. The multiple storage bags 6 can completely separate the bearing steel tube, which can prevent the bearing steel tube from colliding during pickling.
[0024] A frame 8 is fixedly mounted on the processing box 1, and the frame 8 is equipped with a fan that cooperates with the nozzle 9. The frame 8 has a U-shaped structure, as per the instruction manual. Figure 2 As shown, the U-shaped structure of frame 8 has an enclosing tendency, which increases the contact between the bearing steel tube and the drying airflow when rotating. A clamping plate 10 is fixedly installed on the rotating shaft 4, and a second fan that cooperates with the second nozzle 11 is provided on the clamping plate 10. The clamping plate 10 has through holes 12 corresponding to the second nozzle 11, and the through holes 12 correspond to the center hole of the bearing steel tube. According to the instruction manual... Figure 3 As shown, nozzle 2 11 is positioned above the through hole 12 and corresponds to the center hole of the bearing steel tube, so that the drying airflow will flow into the center hole of the bearing steel tube through the through hole 12, thereby drying the inside of the bearing steel tube.
[0025] It should be noted that the specific models and specifications of telescopic pole 2, motor, fan 1, and fan 2 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.
[0026] The functional principle of this utility model can be explained through the following operation methods:
[0027] Place the bearing steel tube inside the storage bag 6. The two ends of the storage bag 6 drive the connecting ears to extend to the positioning post 7, so that the bearing steel tube is in a vertical position.
[0028] The extension end of the telescopic rod 2 retracts, causing the bracket 3 to move downwards. This movement of the bracket 3 causes the bearing steel pipe to extend into the processing box 1 for pickling.
[0029] The motor output drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives another rotating shaft 4 to rotate through the meshing gear, thereby increasing the pickling degree of the bearing steel pipe and the pickling solution.
[0030] When the bearing steel tube needs to be dried after pickling, the output end of the telescopic rod 2 extends and retracts, causing the bearing steel tube to move away from the processing box 1, and the bearing steel tube continues to rotate under the drive of the motor.
[0031] Once the fan is turned on, the drying airflow passes through nozzle 9 to dry the outer wall of the bearing steel pipe.
[0032] When the second fan is turned on, the drying airflow passes through the second nozzle 11 and the through hole 12 to dry the inner wall of the bearing steel tube. The dried bearing steel tube is then removed. The above steps are repeated to dry the next batch of bearing steel tubes.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
