Description

Technical Field

[0001] This utility model belongs to the field of forging production technology, specifically relating to a device for removing impurities from the surface of annular forgings. Background Technology

[0002] A ring forging is a ring-shaped metal part formed during the forging process. The shape of this forging resembles a circular ring or ring structure. Common ring forgings include gear rings, bearing rings, flanges, and other ring-shaped parts. After casting, ring forgings have a large amount of oxide scale, stains, and residue on their surface, which usually needs to be cleaned to facilitate further processing.

[0003] The current methods for cleaning ring forgings generally include grinding, pickling, and sandblasting. While these methods can achieve the desired cleaning effect, they often cannot clean multiple sides of the ring forging simultaneously. After cleaning one side, the forging needs to be flipped over to clean the other side. Therefore, the cleaning process takes up a lot of processing time. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing impurities from the surface of annular forgings, which can simultaneously clean multiple sides of the annular forgings without requiring multiple flipping, resulting in high cleaning efficiency. It is highly practical.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A surface impurity removal device for annular forgings includes a fixed cylinder and an adjusting cylinder, both of which are L-shaped. The adjusting cylinder is movably connected inside the fixed cylinder and is interconnected with it. An adjusting assembly is provided between the fixed cylinder and the adjusting cylinder. A movable plate is movably connected to the side wall of the adjusting cylinder. The movable plate has a hollow structure. The fixed cylinder, adjusting cylinder, and movable plate are each provided with several through holes. A flexible hose is fixedly connected between the movable plate and the adjusting cylinder. Guide wheels are respectively mounted on the side walls of the fixed cylinder, adjusting cylinder, and movable plate.

[0007] The adjusting assembly includes a fixing plate fixedly connected to the side wall of the fixing cylinder near the top. A screw is rotatably connected to the side wall of the fixing plate. A connecting plate is fixedly connected to the side wall of the adjusting cylinder. A screw hole is opened on the side wall of the connecting plate. The screw is threadedly connected to the screw hole. A rotating wheel is fixedly connected to the bottom end of the screw.

[0008] The movable plate is rotatably connected to a pin on its side wall. Both ends of the pin are rotatably connected to the adjusting cylinder. Two torsion springs are mounted on the side wall of the pin.

[0009] A connector is fixedly connected to the top surface of the regulating cylinder, and the connector communicates with the inner cavity of the regulating cylinder.

[0010] A handrail is fixedly connected to the side wall of the fixed cylinder.

[0011] All through holes are opened towards the inside of the fixed cylinder.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a surface impurity removal device for annular forgings. Through the cooperation of a fixed cylinder, an adjusting cylinder, a movable plate, a through hole, and an adjusting component, the distance between the fixed cylinder and the adjusting cylinder can be adjusted according to the thickness of the annular forging, making it easy to hold the device on the annular forging. It can use the impact force of airflow or water flow to clean impurities on the surface of the annular forging, achieving the purpose of multi-face simultaneous cleaning. This solves the problem of wasted time in traditional cleaning methods and effectively improves its practicality. Attached Figure Description

[0020] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a surface impurity removal device for annular forgings includes a fixed cylinder 1 and an adjusting cylinder 2. Both the fixed cylinder 1 and the adjusting cylinder 2 are L-shaped. The adjusting cylinder 2 is movably connected inside the fixed cylinder 1 and is interconnected with each other. An adjusting assembly is provided between the fixed cylinder 1 and the adjusting cylinder 2. A movable plate 7 is movably connected to the side wall of the adjusting cylinder 2. The movable plate 7 is a hollow structure. Several through holes 9 are opened in the fixed cylinder 1, the adjusting cylinder 2, and the movable plate 7. A flexible hose 8 is fixedly connected between the movable plate 7 and the adjusting cylinder 2. Guide wheels 13 are respectively installed on the side walls of the fixed cylinder 1, the adjusting cylinder 2, and the movable plate 7.

[0022] During cleaning, the annular forging can be placed vertically or in other ways so that the device can move along the annular track; or the device can remain stationary while the annular forging is driven to rotate by other means.

[0023] like Figure 1 and Figure 2 As shown, the adjustment assembly includes a fixed plate 3 fixedly connected to the side wall of the fixed cylinder 1 near the top. A screw 5 is rotatably connected to the side wall of the fixed plate 3. A connecting plate 4 is fixedly connected to the side wall of the adjustment cylinder 2. A screw hole is opened on the side wall of the connecting plate 4. The screw 5 is threadedly connected to the screw hole. A rotating wheel 6 is fixedly connected to the bottom end of the screw 5.

[0024] The adjustable component allows for easy lifting and lowering of the adjusting cylinder 2, which is used to adjust the distance between the fixed cylinder 1 and the adjusting cylinder 2, thereby accommodating ring forgings of different thicknesses. It can also be used to clean the surface of ring forgings of different sizes and specifications, thus expanding its application range.

[0025] like Figure 1 and Figure 3 As shown, a pin 10 is rotatably connected to the side wall of the movable plate 7. The two ends of the pin 10 are rotatably connected to the adjusting cylinder 2. Two torsion springs 11 are assembled on the side wall of the pin 10.

[0026] Specifically, the torsion spring 11 is used to give the movable plate 7 the force to return to its original position. When the fixed cylinder 1 and the adjusting cylinder 2 are inserted into the annular forging, the movable plate 7 needs to be opened outward first, and the torsion spring 11 is compressed at the same time. After being inserted into the forging, the force of the torsion spring 11 can drive the movable plate 7 and the guide wheel 13 on the movable plate 7 to be tightly attached to the inner wall of the annular forging. This does not affect the installation of the device on the forging, nor does it affect the cleaning of the inner surface of the forging.

[0027] like Figure 1 and Figure 2 As shown, a connector 12 is fixedly connected to the top surface of the regulating cylinder 2, and the connector 12 communicates with the inner cavity of the regulating cylinder 2. The connector 12 is a quick connector, which is convenient when connecting to external pipelines. The cleaning medium can be gas, liquid, pickling solution or other media. When the cleaning medium enters the regulating cylinder 2, it can be delivered to the movable plate 7 through the hose 8 to achieve the purpose of simultaneous cleaning on all four sides.

[0028] like Figure 2 and Figure 4 As shown, a handrail 14 is fixedly connected to the side wall of the fixed cylinder 1. The handrail 14 facilitates the movement of the device along the trajectory of the forging when cleaning the annular forging, increasing the flexibility and convenience of the cleaning process.

[0029] like Figure 1 and Figure 2As shown, all through holes 9 are opened towards the inside of the fixed cylinder 1. The opening angle of the through holes 9 is not limited to that shown in the attached diagram of this scheme. In practical applications, the through holes 9 can be opened at different angles to make the sprayed cleaning medium more uniform.

[0030] Preferably, a nozzle can also be installed in the through hole 9, and the nozzle can be adjusted in angle to facilitate efficient cleaning of the ring forging.

[0031] The working principle of this utility model is as follows: When it is necessary to clean the surface of the ring forging, first adjust the distance between the fixed cylinder 1 and the adjusting cylinder 2 according to the thickness of the forging. Pull the movable plate 7 outward while the torsion spring 11 contracts, and then lock the fixed cylinder 1 and the adjusting cylinder 2 onto the forging. Then, release the movable plate 7, and the force of the torsion spring 11 will cause the movable plate 7 to stick tightly to the forging. Then, rotate the rotating wheel 6 to drive the screw 5 to rotate. The screw 5 drives the adjusting cylinder 2 to rise and fall through the connecting plate 4. After the guide wheel 13 is in close contact with the forging, the installation is completed. Then, insert the external water pipe or air pipe into the connector 12 and inject high-pressure gas or liquid. The cleaning medium is sprayed onto the surface of the forging through the through hole 9. The impact force of the gas or liquid is used to impact the surface of the forging, washing off the impurities and oxide scale on its surface. The four-sided synchronous cleaning method can clean multiple sides of the forging at the same time, effectively improving its cleaning efficiency. During the cleaning process, the handle 14 can be used to move the forging for mobile cleaning, improving its flexibility of use.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
