Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling equipment, specifically to a billet burr removal device. Background Technology
[0002] Deburring of steel billets before rolling is primarily to ensure a smooth rolling process and the quality of the final product. Burrs can interfere with the normal contact between the workpiece and the rolls during rolling, potentially leading to uneven rolling force distribution and even rolling defects such as surface scratches or dimensional deviations. Furthermore, burrs may detach during rolling, becoming inclusions that contaminate the rolls or embed themselves on the workpiece surface, affecting the product's appearance and performance. If the rolled product contains burrs, it will directly impact its subsequent processing (such as deep drawing and stamping) and overall performance.
[0003] To reduce burr formation, control measures must be implemented at the source, such as improving steel purity, preventing folding during rolling, and ensuring proper die lubrication. Existing burrs need to be removed. Hammer-type deburring machines are a common type of deburring equipment. Their working principle is that during the slab's movement, high-speed rotating hammers repeatedly strike and remove burrs without stopping the slab, saving deburring time. However, this generates significant noise and burr splatter. Therefore, a noise-reducing and burr-splatter-preventing burr removal device needs to be designed. Summary of the Invention
[0004] The purpose of this invention is to provide a steel billet burr removal device, which has the advantages of noise reduction and prevention of burr splashing.
[0005] The technical solution adopted is as follows:
[0006] A billet burr removal device includes a frame, a conveyor roller, a drive mechanism, a cleaning roller, and a noise reduction chamber. The cleaning roller is rotatably mounted on the frame. The drive mechanism is connected to the cleaning roller by a transmission shaft. The cleaning roller includes a roller body, and several hammer blades are connected to the side of the roller body by pins. The frame is equipped with a hydraulic lifting frame. The conveyor roller is mounted on the hydraulic lifting frame. The noise reduction chamber is mounted on the hydraulic lifting frame. A collection box is detachably installed at the lower end of the noise reduction chamber. The cleaning roller is located inside the noise reduction chamber. The noise reduction chamber is equipped with a billet inlet and outlet. Sound insulation material is installed inside the noise reduction chamber.
[0007] Preferably, the interior of the noise reduction chamber is spherical, and the sound insulation material is asbestos cloth.
[0008] Preferably, several iron chains are hung at both the billet inlet and outlet.
[0009] Preferably, the hammer blades are divided into six groups, with multiple hammer blades arranged side by side in each group.
[0010] Preferably, the conveyor roller is equipped with a position sensor, and a controller is mounted on the frame. The controller is connected to both the position sensor and the drive mechanism.
[0011] Compared to existing technologies, the advantages are:
[0012] This invention utilizes a noise-reducing enclosure outside the cleaning roller to reduce noise transmission during the burr removal process on the billet end face and prevent burrs from splashing. The burrs enter the collection box below, offering advantages such as reduced equipment operating noise and improved working environment. A position sensor monitors the position of the billet and transmits the information to the controller, which then activates the drive mechanism to achieve automatic burr removal.

[0018] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:
[0019] Example 1: A billet burr removal device includes a frame 1, a conveyor roller 2, a drive mechanism 3, a cleaning roller 4, and a noise reduction chamber 5. The cleaning roller 4 is rotatably mounted on the frame 1. The drive mechanism 3 and the cleaning roller 4 are connected by a transmission shaft 6. The drive mechanism 3 drives the cleaning roller 4 to rotate on the frame 1 through the transmission shaft 6. The cleaning roller 4 includes a roller body, and several hammers 7 are connected to the side of the roller body by pins.
[0020] The frame 1 is equipped with a hydraulic lifting frame, and the conveyor roller 2 is installed on the hydraulic lifting frame. The hydraulic lifting frame adjusts the height of the conveyor roller 2 so that steel billets of different end face sizes can come into contact with the cleaning roller 4 and the cleaning roller 4 can be used to deburr the steel billets. The noise reduction chamber 5 is installed on the hydraulic lifting frame, and the lower end of the noise reduction chamber 5 is detachably equipped with a collection box 10. The cleaning roller 4 is located inside the noise reduction chamber 5.
[0021] Furthermore, the noise reduction chamber 5 is equipped with a billet inlet / outlet 8. The billet enters from one of the billet inlets / outlets 8 for burr removal and then exits from the other billet inlet / outlet 8. The noise reduction chamber 5 is equipped with sound insulation material, which reduces noise transmission and lowers equipment operating noise. Additionally, the burrs are confined within the noise reduction chamber 5, reducing burr splashing and improving the working environment.
[0022] Example 2: A billet burr removal device includes a frame 1, a conveyor roller 2, a drive mechanism 3, a cleaning roller 4, and a noise reduction chamber 5. The cleaning roller 4 is rotatably mounted on the frame 1. The drive mechanism 3 is connected to the cleaning roller 4 by a transmission shaft 6. The drive mechanism 3 drives the cleaning roller 4 to rotate on the frame 1 through the transmission shaft 6. The cleaning roller 4 includes a roller body. Several hammers 7 are connected to the side of the roller body by pins. The hammers 7 are divided into six groups, and multiple hammers 7 are arranged in parallel in each group.
[0023] The frame 1 is equipped with a hydraulic lifting frame, and the conveyor roller 2 is installed on the hydraulic lifting frame. The hydraulic lifting frame adjusts the height of the conveyor roller 2 so that steel billets of different end face sizes can come into contact with the cleaning roller 4 and the cleaning roller 4 can be used to deburr the steel billets. The noise reduction chamber 5 is installed on the hydraulic lifting frame, and the lower end of the noise reduction chamber 5 is detachably equipped with a collection box 10. The cleaning roller 4 is located inside the noise reduction chamber 5.
[0024] Furthermore, the noise reduction chamber 5 is equipped with a billet inlet / outlet 8. The billet enters from one of the billet inlets / outlets 8 for burr removal and then exits from the other billet inlet / outlet 8. Several iron chains 9 are hung at each of the billet inlets / outlets 8. The iron chains 9 do not affect the entry and exit of the billet and can block the burrs.
[0025] The noise reduction chamber 5 is equipped with sound insulation material, which reduces noise transmission and lowers equipment operating noise. Furthermore, burrs are confined within the noise reduction chamber 5, reducing burr splashing and improving the working environment. The interior of the noise reduction chamber 5 is spherical, and the sound insulation material is asbestos cloth.
[0026] The conveyor rollers are equipped with position sensors, and the frame is equipped with a controller. The controller is connected to both the position sensors and the drive mechanism. The position sensors monitor the position of the steel billet and transmit the information to the controller. The controller then controls the drive mechanism to start, thereby achieving automatic burr removal.
[0027] The work process is as follows:
[0028] The collection box 10 is installed below the noise reduction chamber 5. The height of the hydraulic lifting frame is adjusted according to the end face size of the billet so that the lower end of the billet is matched with the hammer blade 7. The conveyor roller 2 transports the billet. The position sensor monitors the position of the billet and transmits the information to the controller. When the billet is about to reach the noise reduction chamber 5, the controller starts the drive mechanism 3 to drive the cleaning roller 4 to rotate. The hammer blade 7 removes the burrs at the end of the billet. The removed burrs enter the noise reduction chamber 5 and then the collection box 10. This has the advantages of reducing equipment operating noise and improving the working environment.
