Description

Technical Field

[0001] This application relates to the technical field of cage manufacturing, and in particular to an acid pickling apparatus for forming the inner slope of a needle roller bearing cage. Background Technology

[0002] Cage pickling is a key process in bearing manufacturing and maintenance. It is mainly used to remove surface oxides, oil stains, burrs and other impurities to ensure surface smoothness and electrical conductivity, thereby guaranteeing the service life and safety of the bearing.

[0003] After the inner slope of the needle roller bearing cage is formed, there is oil and oxide on the inner wall of the cage groove, which needs to be pickled to ensure its surface flatness.

[0004] Existing pickling equipment has a relatively simple structure, generally consisting of a production line with an acid soaking tank, a rinsing tank, a neutralization tank, and a spray washing tank arranged sequentially. The holders are manually placed into each tank and then retrieved. The overall labor intensity is high, and the long production line requires a large amount of space.

[0005] Therefore, there is an urgent need to improve the existing pickling equipment. Utility Model Content

[0006] The purpose of this application is to provide an acid pickling apparatus for forming the inner slope of the needle roller bearing cage, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides an acid pickling apparatus for forming the inner slope of a needle roller bearing cage, employing the following technical solution: A pickling device for forming the inner slope of a needle roller bearing cage includes a central support mechanism and acidic soaking tank, rinsing tank, neutralization tank, spray washing tank, and air drying tank evenly arranged around the central support mechanism. The central support mechanism includes a base, a cam divider, a turntable, a mounting frame, and a lifting assembly. The cam divider is installed at the bottom of the base, and the turntable is rotatably connected to the top of the base. The cam divider drives the turntable to rotate. The mounting frame is vertically fixed on the turntable. The lifting assembly includes a winch and a lifting frame. The lifting frame is slidably connected to the side of the mounting frame. The winch drives the lifting frame to lift. A storage basket is matched inside the lifting frame.

[0008] The bottom of the acidic soaking tank is equipped with multiple ultrasonic transducers, and each ultrasonic transducer is externally connected to an ultrasonic generator.

[0009] Spray pipes and water-cutting air pipes are installed on the inner walls of both the rinsing pool and the spraying pool.

[0010] A blower is installed on the inner wall of the drying tank.

[0011] The storage basket is made of wire mesh, and multiple placement slots are evenly arranged on the surface of the storage basket.

[0012] Preferably, the bottom surface of the lifting frame is provided with a permeable grid groove.

[0013] By adopting the above technical solution, the permeable grid channel can facilitate the passage of liquid, thereby reducing the resistance when the lifting frame enters and leaves the liquid, and thus better immersing the storage basket in the liquid.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the pickling device for the inner slope forming process of the needle roller bearing cage is arranged in a ring around the central bearing mechanism, with an acid soaking tank, rinsing tank, neutralization tank, spray washing tank and air drying tank arranged in sequence. The whole is circular, and multiple pickling devices can be arranged in the workshop, which greatly saves workshop space. At the same time, the pickling device has a high degree of automation and low labor intensity for workers during operation. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses an acid pickling apparatus for forming the inner slope of a needle roller bearing cage, referring to... Figure 1-4The system includes a central support mechanism 1 and acidic soaking tank 2, rinsing tank 3, neutralization tank 4, spray washing tank 5, and air drying tank 6 evenly arranged around the central support mechanism 1. The central support mechanism 1 includes a base 11, a cam divider 12, a turntable 13, a mounting frame 14, and a lifting assembly. The cam divider 12 is installed at the bottom of the base 11, and the turntable 13 is rotatably connected to the top of the base 11. The cam divider 12 is used to drive the turntable 13 to rotate. The mounting frame 14 is vertically fixed on the turntable 13. The lifting assembly includes a winch 15 and a lifting frame 16. The lifting frame 16 is slidably connected to the mounting frame 14 on its side. The winch 15 is used to drive the lifting frame 16 to lift. A storage basket 7 is matched and installed inside the lifting frame 16.

[0022] Multiple ultrasonic transducers 21 are installed at the bottom of the acid soaking tank 2. An ultrasonic generator is connected to the ultrasonic transducer 21. Spray pipes 31 and water-cutting air pipes 32 are installed on the inner walls of the rinsing tank 3 and the spray washing tank 5. A blower 61 is installed on the inner wall of the drying tank 6.

[0023] The acidic soaking tank 2 enables ultrasonic washing, which can quickly remove oil and oxides adhering to the surface of the cage.

[0024] Reference Figure 4 The storage basket 7 is made of mesh plate, and multiple placement slots 71 are evenly arranged on the surface of the storage basket 7.

[0025] The bottom surface of the lifting frame 16 is provided with a water-permeable grid groove 161, which allows liquid to pass through easily, thereby reducing the resistance when the lifting frame 16 enters and leaves the liquid, and thus better immersing the storage basket 7 into the liquid.

[0026] The implementation principle of the pickling device for forming the inner slope of the needle roller bearing cage according to an embodiment of this application is as follows: During use, the staff places the storage basket 7 filled with retainers into the lifting frame 16 from the top of the drying tank 6. The cam divider 12 drives the turntable 13 to rotate once, causing the lifting frame 16 to rotate to the top of the acid soaking tank 2. At this time, the winch 15 lowers the lifting frame 16 into the acid soaking tank 2, immersing the retainers in the acidic solution. After soaking for a certain period of time, the winch 15 drives the lifting frame 16 to rise. The cam divider 12 rotates once again, causing the lifting frame 16 to rotate to the top of the rinsing tank 3. The winch 15 lowers the lifting frame 16 into the rinsing tank 3 again, and the spray pipe 31 rinses the retainers to wash away the acidic solution remaining on their surface, preventing them from entering the subsequent neutralization tank 4. Subsequently, the cam divider 12 drives the lifting frame 16 into the neutralization tank 4, the spray washing tank 5, and the drying tank 6 in sequence. During this process, the retainer in the neutralization tank 4 undergoes an acid-base reaction to adjust the pH value, remove acid washing residue, reduce corrosivity, and promote the precipitation of heavy metals, thereby achieving clean production and environmentally friendly emissions. Afterward, it enters the spray washing tank 5 for cleaning and finally enters the drying tank 6 for drying. Finally, the staff replaces a new batch of retainers and repeats the above actions. The cleaning efficiency is high and the labor intensity of the staff is low.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
