Description

Technical Field

[0001] This utility model relates to the technical field of burr removal devices, and mainly to a double-roller burr removal device. Background Technology

[0002] Deburring devices are typically installed between the rollers following the flame cutting machine in a slab continuous casting production line. During flame cutting of continuously cast slabs, many cutting residues adhere to the cutting area, forming burrs. If these burrs are not removed and the slab is directly sent to the next rolling process, it will damage the surface of the rolls, affecting their lifespan and ultimately impacting the quality of the steel plate. In recent years, with the development of direct hot-feeding technology for slabs and the continuous improvement of hot charging and hot-feeding rates, the demand for defect-free slabs has increased accordingly. Therefore, online burr removal has become an indispensable part of slab production.

[0003] There are generally three types of deburring devices in related technologies. The first type is called the scraper moving type, where the billet is pressed tightly on the roller conveyor and the scraper moves to cut off the burrs. The second type is the billet moving type, where the scraper is pressed on the lower surface of the billet and the billet moves to cut off the burrs. The third type is called the hammer type, which uses a high-speed rotating hammer to knock off the burrs.

[0004] When implementing the above-mentioned deburring device, the inventors discovered that conventional deburring devices also have the following problems:

[0005] Conventional deburring devices are all single-roller or single-blade structures, which can only remove burrs from one side of the casting billet. During use, the casting billet needs to be flipped over, which affects the deburring efficiency. Utility Model Content

[0006] This invention aims to solve at least one problem existing in the prior art. Therefore, the purpose of this invention is to provide a double-roller burr removal device that uses upper and lower double rollers clamping together to remove cutting marks from the upper and lower surfaces of the head and tail of the cast billet.

[0007] To achieve the above objectives, this utility model proposes:

[0008] A double-roller burr removal device includes a frame and a drive unit. The frame has a material inlet and a chamber is formed inside the frame. Two deburring rollers are arranged in the chamber of the frame. The two deburring rollers have the same structure and are distributed opposite to each other with a gap between them.

The pressure plates are located at both ends of the roller body. The pins are inserted along the axial direction of the roller body and fixed at both ends to the pressure plates. The several blades are arranged in different installation spaces and located on the pins.

[0010] Furthermore, the blade has a waist-shaped hole, and the pin has a circular cross-section.

[0011] Furthermore, a height difference is formed between the blade and the pressure plate.

[0012] Furthermore, the pressure plate and the spacer are provided with several through holes at corresponding positions, and the pin is inserted into the through holes.

[0013] Furthermore, the spacer and the roller body are an integral structure.

[0014] Furthermore, the drive device includes a motor and a universal coupling, one end of which is connected to the drive shaft of the motor and the other end of which is connected to the deburring roller.

[0015] Furthermore, it also includes a mesh cover, which is disposed outside the universal coupling.

[0033] Please refer to the following for details. Figure 1A double-roller deburring device includes a frame 1 and a drive unit 2. The frame 1 is made of multiple steel plates by screws or welding. A feed port 11 is provided on the frame 1. The billet enters the interior of the frame 1 through the feed port 11, forming a chamber inside the frame 1. The chamber is interconnected with the feed port 11. Two deburring rollers 3 are provided in the chamber of the frame 1. The two deburring rollers 3 have the same structure and are distributed vertically opposite each other with a gap between them. One end of the deburring roller 3 is connected to the drive unit 2, and the other end is located in the bearing cover 4. Under the action of the drive unit 2, the two deburring rollers 3 can be driven to rotate in opposite directions, thereby removing the cutting marks on the upper and lower surfaces of the billet head and tail.

[0034] Based on the above technical means: when the burr removal device is used for deburring, the cutting nodules on the upper and lower surfaces of the billet will be removed by the upper and lower deburring rollers 3 respectively, which can remove burrs from the upper and lower surfaces of the billet at the same time, thus improving the efficiency of deburring the billet.

[0035] Please refer to the following for details. Figure 1 The drive unit 2 includes a motor 21 and a universal coupling 22. One end of the universal coupling 22 is connected to the drive shaft of the motor 21, and the other end is connected to the deburring roller 3. That is, the motor 21 is connected to the deburring roller 3 through the universal coupling 22. The advantage of the universal coupling 22 is that it can transmit motion and torque, and has different degrees of axial, angular compensation and radial compensation. Even if the drive shaft of the motor 21 and the axis of the deburring roller 3 are not on the same straight line, the deburring roller 3 can still be driven to rotate.

[0036] Please refer to the following for details. Figure 1 A double-roller burr removal device further includes a mesh cover 5, which is placed outside the universal coupling 22 and serves to protect the universal coupling 22.

[0037] Please refer to the following for details. Figure 2 and 3 The deburring roller 3 includes a roller body 31, two pressure plates 32, several pins 33, and several blades 34. The roller body 31 is provided with several spacers 311 that are arranged alternately along its axial direction. An installation space 312 is formed between two adjacent spacers 311. The pressure plates 32 are located at both ends of the roller body 31. The pins 33 are inserted along the axial direction of the roller body 31 and fixed at both ends to the pressure plates 32. Several blades 34 are arranged on the pins 33 and located in different installation spaces 312.

[0038] Based on the above technical means, the blades 34 adopt a complementary arrangement, that is, the blades 34 are arranged in different installation spaces 312 and located on the pin 33. Compared with the traditional blades 34 covering the entire roller body 31, the complementary arrangement of the blades 34 in this application can effectively reduce the overall weight of the deburring roller 3 and the centrifugal force during operation.

[0039] Specifically, the pressure plate 32 and the spacer 311 have several through holes (not shown in the figure) at corresponding positions, and the pin 33 is inserted into the through holes.

[0040] Please refer to the following for details. Figure 2 There is a height difference between the blade 34 and the pressure plate 32, that is, the head of the blade 34 needs to be higher than the pressure plate 32, so that the blade 34 can perform deburring on the casting billet.

[0041] Please refer to the following for details. Figure 4 The blade 34 has a waist-shaped hole 341, and the cross-section of the pin 33 is circular. The design of the waist-shaped hole 341 allows the blade 34 to have a space for extension and retraction. When the blade 34 comes into contact with the billet, the blade 34 can retract, preventing the blade 34 from colliding hard with the billet and protecting the blade 34.

[0042] Optionally, the spacer 311 and the roller body 31 are integral structures, cast using an integral molding method; or, the spacer 311 and the roller body 31 are cast separately and fixed together by welding.

[0043] In this embodiment, the spacer 311 and the roller 31 are preferably integrated into one structure, which has higher strength and greater stability.

[0044] This utility model relates to a double-roller burr removal device, the working principle of which is explained in conjunction with the accompanying drawings:

[0045] Under the action of the conveying roller, the billet enters from the feed port 11 between the two deburring rollers 3. The drive device 2 drives the two deburring rollers 3 to rotate in opposite directions. The upper and lower double deburring rollers 3 clamp and convey the billet, thereby removing the cutting nodules on the upper and lower surfaces of the billet and improving the deburring efficiency of the billet.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
