[0002] Alloy steel forgings are commonly used components in steel structures. To ensure the stability of the steel structure, the quality of alloy steel forgings is very important. Therefore, during the production process of alloy steel forgings, they need to be carburized.

[0003] When using existing carburizing equipment, uneven distribution of carbon medium is prone to occur during the carburizing process, resulting in an uneven carburized layer on the surface of alloy forgings. This leads to certain problems with the overall quality of alloy steel forgings and is detrimental to the use of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven distribution of carbon media during carburizing, resulting in an uneven carburized layer on the surface of alloy forgings, which leads to certain problems with the overall quality of alloy steel forgings and is not conducive to the use of the equipment. Therefore, this invention proposes a carburizing equipment for anti-wear and corrosion-resistant treatment of alloy steel forgings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A fixed base plate is installed inside the heating vessel via an adjustment structure. A fixed tank is fixedly connected to the top end of the fixed base plate. A connecting cover plate is threaded onto the top end of the fixed tank. A motor is fixedly installed on the fixed base. A rotating rod is fixedly connected to the output end of the motor. The rotating rod penetrates the inner wall of the heating vessel and extends to the inner side of the heating vessel. A fixed cam is fixedly connected to the end of the rotating rod located inside the heating vessel.

[0008] Preferably, the adjustment structure includes a hydraulic telescopic unit rotatably mounted on the inner wall of the fixed base. The hydraulic telescopic unit penetrates the inner wall of the heating vessel and is slidably connected to the fixed base plate. A sliding block is fixedly connected to the top of the hydraulic telescopic unit. A sliding groove corresponding to the sliding block is opened at the bottom of the fixed base plate. An elastic element is fixedly connected to the side wall of the sliding block.

[0009] Preferably, the direction of the sliding groove corresponds to the shape and position of the fixed cam, and both the fixed base plate and the outer side of the fixed cam are covered with a protective layer.

[0010] Preferably, a connecting sleeve is slidably sleeved on the hydraulic telescopic unit, the connecting sleeve is rotatably connected to the upper inner wall of the fixed base, and the connecting sleeve and the rotating rod are connected by a belt drive structure.

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3 A carburizing apparatus for anti-wear and corrosion-resistant surface treatment of alloy steel forgings, comprising:

[0020] A fixed base 1 is fixedly connected to a heating vessel 2 at its top. A fixed cover plate 3 is fixedly snapped onto the top of the heating vessel 2. A fixed base plate 5 is installed inside the heating vessel 2 through an adjustment structure. A fixed tank 6 is fixedly connected to the top of the fixed base plate 5. A connecting cover plate 7 is threaded onto the top of the fixed tank 6. A motor 8 is fixedly installed on the fixed base 1. A rotating rod 9 is fixedly connected to the output end of the motor 8. The rotating rod 9 penetrates the inner wall of the heating vessel 2 and extends to the inner side of the heating vessel 2. A fixed cam 10 is fixedly connected to one end of the rotating rod 9 located inside the heating vessel 2.

[0021] When the motor 8 is started, the output end of the motor 8 drives the rotating rod 9 to rotate, which causes the fixed cam 10 fixedly installed at the top of the rotating rod 9 to rotate. When the fixed cam 10 rotates, it will press the fixed base plate 5 to move. In conjunction with the elastic element 15, the fixed base plate 5 will vibrate, causing the fixed tank 6 to vibrate as well, so that the liquid carbon medium can fully contact the alloy steel forging.

[0022] The adjustment structure includes a hydraulic telescopic unit 4 rotatably mounted on the inner wall of the fixed base 1. The hydraulic telescopic unit 4 penetrates the inner wall of the heating vessel 2 and is slidably connected to the fixed base plate 5. A sliding block 13 is fixedly connected to the top of the hydraulic telescopic unit 4. A sliding groove 14 corresponding to the sliding block 13 is opened at the bottom of the fixed base plate 5. An elastic element 15 is fixedly connected to the side wall of the sliding block 13. The end of the elastic element 15 away from the sliding block 13 is fixedly connected to the inner wall of the sliding groove 14.

[0023] The position of the fixed base plate 5 and the fixed tank 6 can be adjusted by the hydraulic telescopic unit 4, so that the fixed tank 6 can be moved to the outside of the heating vessel 2, thereby making it convenient to send the alloy forging into the fixed tank.

[0024] The direction of the sliding groove 14 corresponds to the shape and position of the fixed cam 10, so that when the fixed cam 10 presses the fixed base plate 5, the fixed base plate 5 can rotate without motion interference. The outer sides of the fixed base plate 5 and the fixed cam 10 are covered with protective layers to protect the fixed base plate 5 and the fixed cam 10. At the same time, when the fixed base plate 5 moves to the lowest point under the action of the hydraulic telescopic unit 4, its position corresponds to the fixed cam 10.

[0025] A connecting sleeve 11 is slidably sleeved on the hydraulic telescopic unit 4. The connecting sleeve 11 is rotatably connected to the upper inner wall of the fixed base 1. The connecting sleeve 11 and the rotating rod 9 are connected by a belt drive structure 12. When the rotating rod 9 rotates, the connecting sleeve 11 rotates with it under the action of the belt drive structure 12, which drives the hydraulic telescopic unit 4 to rotate as well, so that the alloy steel forging in the fixed tank 6 also rotates, making the carburized layer more uniform during the carburizing process.

[0026] The fixed base 1 is equipped with a controller corresponding to the hydraulic telescopic unit 4 and the motor 8. The controller is an existing device that is compatible with the hydraulic telescopic unit 4 and the motor 8, so its working principle will not be described in detail. The fixed tank 6 is filled with liquid carbon medium, which can uniformly carburize the alloy steel forgings. At the same time, it also prevents the alloy steel forgings from contacting the air, causing them to be oxidized by the air.

[0027] In this invention, when the device is in use, the connecting cover plate 7 is opened, and the alloy steel forging is placed into the fixed tank 6. The fixed base plate 5 and the fixed tank 6 are moved into the heating kettle 2 by the hydraulic telescopic unit 4. The heating kettle 2 is used for heating and carburizing. At the same time, the motor 8 is started. The output end of the motor 8 drives the rotating rod 9 to rotate, thereby causing the fixed cam 10 fixedly installed at the top of the rotating rod 9 to rotate. When the fixed cam 10 rotates, it will squeeze the fixed base plate 5 to move it. With the cooperation of the elastic element 15, the fixed base plate 5 vibrates, causing the fixed tank 6 to vibrate as well. This allows the liquid carbon medium to fully contact the alloy steel forging. Moreover, when the rotating rod 9 rotates, the connecting sleeve 11 rotates under the action of the belt drive structure 12, which drives the hydraulic telescopic unit 4 to rotate as well, causing the alloy steel forging in the fixed tank 6 to rotate as well. This makes the carburized layer more uniform during the carburizing process.

[0028] 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.
