Description

Technical Field

[0001] This utility model relates to the field of casting and forging processing technology, specifically to a device for removing oxide scale from casting and forgings. Background Technology

[0002] Castings and forgings are metal parts manufactured through casting and forging processes, encompassing sand casting, die forging, and ring forging. According to a 2024 industry analysis, forging optimizes fiber structure through solid-state metal plastic deformation, while casting relies on liquid metal filling to achieve complex internal cavity formation. In the energy equipment sector, high-temperature alloy castings and forgings used in ultra-supercritical units support the operation of megawatt-level power generation equipment, and approximately 35% of engine components in the aerospace field are manufactured using precision die forging processes. Domestic companies such as Hefei Forging & Stamping Intelligent Equipment Co., Ltd. have developed fast forging hydraulic press production lines that utilize big data technology to control forging precision down to the millimeter level.

[0003] Oxide scale generated during existing forging processes significantly affects forging quality and die life. Oxide scale is formed by the reaction of iron and oxygen at high temperatures. Composed of oxides, its structure is dense and its adhesion is strong. During forging, it is easily pressed into the interior of the forging, resulting in surface roughness, pitting, and even internal structural defects, which seriously reduces mechanical properties and yield. Therefore, a device for removing oxide scale from cast forgings is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing oxide scale from cast forgings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing oxide scale from cast forgings, comprising a housing and an electric telescopic rod. A door is installed at the front end of the housing, and the door is rotatably connected to the housing. The electric telescopic rod is installed inside the housing, on the upper left side, and a clamping frame is installed at the right end of the electric telescopic rod. A motor is installed at the rear end of the clamping frame, and an electric telescopic rod is installed at the front end of the clamping frame. A thin cylindrical part on the clamping block contacts the cast forging, reducing the clamping area and facilitating cleaning. The electric telescopic rod extends and retracts to adjust the distance between the cast forging and the descaling component until the high-pressure fan-shaped water jet from the descaling component completely covers the cast forging, facilitating thorough cleaning.

[0006] Furthermore, one end of the electric telescopic rod is equipped with a rotating shaft, and a clamping block is installed on one side of the rotating shaft. The motor drives the clamping block on one side to rotate, and the clamping block on the other side can rotate through the rotating shaft, thereby causing the casting forging to rotate in the clamping frame under the drive of the motor.

[0007] Furthermore, a phosphorus removal component is provided on the right side of the clamping block, and a connecting pipe is connected to the right side of the phosphorus removal component.

[0008] Furthermore, the descaling assembly includes a diversion pipe and nozzles, with a nozzle installed on one side of the diversion pipe. The diversion pipe distributes high-pressure water flow to each nozzle, forming a fan-shaped water jet with strong impact force, which is sprayed onto the surface of the forging, causing the oxide scale to be cut, rapidly cooled and contracted, and peeled off from the substrate, thereby achieving the cleaning purpose.

[0009] Furthermore, one end of the connecting pipe is connected to a water pump, and the water pump and the connecting pipe are threaded together. The water pump transports water from the water tank to the distribution pipe through the connecting pipe.

[0010] Furthermore, a collection frame is installed at the bottom of the interior of the box, and the collection frame is slidably connected to the box. The water flow carries the oxide scale into the collection frame, and the collection frame slides out of the box for easy subsequent cleaning.

[0011] Furthermore, a filter screen is installed inside the lower part of the collection frame, and a water tank is provided below the filter screen. The filter screen filters out the oxide scale for subsequent processing, while preventing the oxide scale from clogging the water pump. The water passes through the filter screen and flows back into the water tank for easy reuse.

[0012] Furthermore, an observation window is installed inside the cabinet door, and a handle is installed at the front end of the cabinet door. The cabinet door can be closed by using the handle, and the observation window facilitates observation of the internal cleaning process.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: The forging is placed between clamping blocks by opening the box door with a handle. The electric telescopic rod extends to drive the clamping blocks to move and fix the forging. The thin cylinders on the clamping blocks contact the forging, reducing the clamping area and facilitating cleaning. A motor drives one side of the clamping blocks to rotate, while the other side rotates via a rotating shaft, allowing the forging to rotate within the clamping frame to adjust the cleaning surface for thorough cleaning. The electric telescopic rod extends to adjust the distance between the forging and the descaling assembly, ensuring that the high-pressure fan-shaped water flow completely covers the forging. After closing the box door, the internal cleaning process can be observed through the observation window. The water pump delivers water from the tank to the distribution pipe via a connecting pipe, which then distributes the water to each nozzle to form a fan-shaped water jet, spraying and cutting away the oxide scale. The water flow carries the oxide scale into the collection frame, where a filter screen filters the oxide scale to prevent clogging of the water pump. The water flows back to the tank for recycling. After cleaning, the motor drives the forging to rotate rapidly to dry and prevent rust. 1. This utility model allows the casting forging to be placed between clamping blocks by opening the box door with a handle. The extension of the electric telescopic rod drives the clamping blocks to move and clamp the casting forging between the blocks. The thin cylinders on the clamping blocks contact the casting forging, reducing the clamping area and facilitating cleaning. The motor drives one side of the clamping block to rotate, and the other side of the clamping block can be rotated through a rotating shaft, thereby allowing the casting forging to rotate in the clamping frame under the drive of the motor, thus adjusting the cleaning surface of the casting forging for easy and thorough cleaning. At the same time, the extension of the electric telescopic rod adjusts the distance between the casting forging and the descaling component until the high-pressure fan-shaped water jet sprayed by the descaling component completely covers the casting forging, facilitating thorough cleaning. 2. This utility model features a handle to close the cabinet door, and an observation window for easy observation of the internal cleaning process. A water pump delivers water from the tank to a distribution pipe via a connecting pipe. The distribution pipe then distributes the high-pressure water flow to various nozzles, forming a powerful fan-shaped water jet that is sprayed onto the surface of the forging. This cuts off the oxide scale, causes it to shrink rapidly due to cooling, and peels it off from the substrate, thus achieving the cleaning purpose. The water flow carries the oxide scale into a collection frame, where a filter screen removes it for subsequent processing and prevents the oxide scale from clogging the water pump. The water flows back to the tank through the filter screen for easy reuse, saving water resources. After cleaning, a motor drives the casting forging to rotate rapidly and spin dry, preventing rust.

Detailed Implementation

[0016] like Figure 1-3 As shown, a descaling device for cast forgings includes a housing 1 and an electric telescopic rod 5. A door 2 is installed at the front end of the housing 1, and the door 2 is rotatably connected to the housing 1. The electric telescopic rod 5 is installed inside the housing 1 on the upper left side, and a clamping frame 6 is installed at the right end of the electric telescopic rod 5. A motor 10 is installed at the rear end of the clamping frame 6, and an electric telescopic rod 7 is installed at the front end of the clamping frame 6. A rotating shaft 8 is installed at one end of the electric telescopic rod 7, and a clamping block 9 is installed on one side of the rotating shaft 8. During operation, the handle 4 is held to open the door 2, and the cast forging is placed between the clamping blocks 9. Subsequently, the electric telescopic rod 7 extends, pushing the clamping blocks 9 to move and securely clamp the forging. The thin cylinders on the clamping blocks 9 contact the forging, effectively reducing the clamping area and facilitating subsequent cleaning. The motor 10 drives one clamping block 9 to rotate, while the other clamping block 9 rotates synchronously via the rotating shaft 8, causing the forging to rotate within the clamping frame 6, thereby adjusting the cleaning surface and ensuring thorough cleaning. At the same time, the electric telescopic rod 5 extends and retracts, precisely adjusting the distance between the forging and the descaling component 11 until the high-pressure fan-shaped water jet sprayed by the descaling component 11 completely covers the forging, achieving a highly efficient and comprehensive cleaning effect.

[0017] like Figure 1-3 As shown, a phosphorus removal component 11 is provided on the right side of the clamping block 9, and a connecting pipe 12 is connected to the right side of the phosphorus removal component 11. The phosphorus removal component 11 includes a diversion pipe 1101 and a nozzle 1102, and a nozzle 1102 is installed on one side of the diversion pipe 1101. A water pump 13 is connected to one end of the connecting pipe 12, and the water pump 13 and the connecting pipe 12 are threadedly connected. A collection frame 14 is installed at the bottom inside the box 1, and the collection frame 14 is slidably connected to the box 1. A filter screen 15 is installed at the bottom inside the collection frame 14, and a water tank 16 is provided below the filter screen 15. An observation window 3 is installed inside the box door 2, and a handle 4 is installed at the front end of the box door 2. During operation, the box door 2 is closed by the handle 4, and the observation window 3 facilitates real-time monitoring of the internal cleaning process. Water pump 13 delivers water from water tank 16 to distribution pipe 1101 via connecting pipe 12. Distribution pipe 1101 evenly distributes high-pressure water flow to each nozzle 1102. Nozzles 1102 form a powerful fan-shaped water jet that sprays onto the surface of the forging, cutting off the oxide scale, rapidly cooling and shrinking it, and peeling it off from the substrate, achieving efficient cleaning. The water flow carries the oxide scale into collection frame 14, where filter screen 15 filters it for subsequent processing and prevents it from clogging water pump 13. The filtered water flows back to water tank 16 through filter screen 15, achieving recycling and saving water resources. After cleaning, motor 10 drives the casting forging to rotate rapidly and spin dry, effectively preventing rust.

[0018] Working Principle: When using this casting forging descaling device, firstly, during operation, hold handle 4 to open the chamber door 2 and place the casting forging to be treated between the clamping blocks 9. Then, the electric telescopic rod 7 extends, pushing the clamping blocks 9 to move and firmly clamp the casting forging, ensuring its stable fixation. The clamping blocks 9 are equipped with thin cylinders that contact the surface of the casting forging, effectively reducing the clamping area, facilitating subsequent cleaning, and reducing damage to the forging during clamping. Next, the motor 10 starts, driving one side of the clamping block 9 to rotate, while the other side rotates synchronously via the rotating shaft 8, causing the casting forging to rotate as a whole within the clamping frame 6. This design allows for flexible adjustment of the cleaning surface of the casting forging, ensuring thorough cleaning of every part. Simultaneously, the electric telescopic rod 5 extends and retracts according to cleaning requirements, precisely adjusting the distance between the casting forging and the descaling component 11 until the high-pressure fan-shaped water jet from the descaling component 11 completely covers the surface of the casting forging, providing strong support for comprehensive cleaning. After completing the above adjustments, close the cabinet door 2 using handle 4, and the internal cleaning process can be clearly observed through the observation window 3. Water pump 13 draws water from the water tank 16 and delivers it to the distribution pipe 1101 via connecting pipe 12. The distribution pipe 1101 evenly distributes the high-pressure water flow to each nozzle 1102, which transforms the water flow into powerful, fan-shaped water jets that spray onto the surface of the forging. These fan-shaped water jets precisely cut the oxide scale, causing it to rapidly cool and shrink, ultimately peeling it off from the substrate, achieving efficient cleaning. The oxide scale generated during the cleaning process falls into the collection frame 14 with the water flow, while the filter screen 15 filters the oxide scale out of the water for subsequent centralized processing, effectively preventing oxide scale from clogging the water pump 13. The filtered water flows back to the water tank 16 through the filter screen 15, achieving water resource recycling, which is both environmentally friendly and water-saving. After cleaning, motor 10 is restarted, driving the casting forging to rotate rapidly. Centrifugal force is used to dry the surface moisture, effectively preventing rust caused by moisture residue during storage.
