Description

Technical Field

[0001] This utility model relates to the technical field of deburring devices, and mainly to a deburring device applicable to steel billets of different thicknesses. Background Technology

[0002] 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 roll surface, affect the roll life, and also affect the quality of the steel plate. In recent years, with the development of direct hot-feeding technology for slabs, the hot charging and hot-feeding rate has been continuously improving, and the demand for defect-free slabs has increased accordingly. Therefore, online burr removal of slabs 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] 1. The height of the deburring roller in conventional deburring devices is not adjustable, which cannot adapt to casting billets of different thicknesses, resulting in low production efficiency.

[0006] 2. Conventional deburring devices are all single-roller or single-blade structures, which can only remove burrs from one side of the billet. During use, the billet needs to be flipped over, which affects the deburring efficiency. Utility Model Content

[0007] This invention aims to solve at least one problem existing in the prior art. Therefore, the purpose of this invention is to propose a deburring device suitable for steel billets of different thicknesses. Through servo-driven automatic precise positioning and program calculation of the upper and lower hydraulic cylinders, it can handle billets of all thicknesses, achieving a one-time solution.

[0008] To achieve the above objectives, this utility model proposes:

[0009] A deburring device suitable for steel billets of different thicknesses includes a frame and two sets of first drive devices. The frame is equipped with two deburring rollers, including a first deburring roller and a second deburring roller. The first deburring roller and the second deburring roller are distributed opposite to each other and are spaced apart. The two ends of the first deburring roller and the second deburring roller are located in a sliding bearing cover, and one end of the first deburring roller is connected to the first drive device. The top and bottom of the frame are equipped with second drive devices, which are connected to the sliding bearing cover.

[0010] Furthermore, several guide blocks are provided on both sides of the frame, wherein the guide blocks are arranged opposite each other in pairs, and a guide groove is formed between the two opposite guide blocks, and the sliding bearing cover is located in the guide groove.

[0011] Furthermore, the guide block has a waist-shaped hole, and an adjustable component is provided on the outside of the guide block. The adjustable component includes a fixing plate, multiple screws and multiple nuts. The fixing plate is fixed to the outside of the guide block, the screws are mounted on the fixing plate, and the fixing plate is locked on the screws and located on both sides of the fixing plate.

[0012] Furthermore, a connecting cavity is provided on the sliding bearing cover, and one end of the output shaft of the second drive device is located in the connecting cavity and fixed by fasteners.

[0013] Furthermore, the first 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 is connected to the first burr roller and the second burr roller.

[0014] Furthermore, the first burr roller and the second burr roller have the same structure. The first burr roller and the second burr roller include a roller body, two pressure plates, several pins and several blades. The roller body is provided with several spacers that are alternately distributed along its axial direction. An installation space is formed between two adjacent spacers. 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. Several blades are arranged in different installation spaces and located on the pins.

[0015] Furthermore, the frame and motor are provided with several anchor bolts at their bottom.

[0016] Furthermore, the bottom of the frame is provided with an inclined material drop chute.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model can handle billets of all thicknesses by using servo automatic precise positioning and program calculation of the upper and lower second drive devices (cylinders) to achieve a one-time solution; the removal depth can be set according to the billet material, and the speed of the second drive device (cylinder) is controlled by a proportional valve on the hydraulic control system, plus the rotation speed of the upper and lower burr rollers is controlled by frequency conversion, so as to achieve free control of the removal depth.

[0019] 2. This utility model adopts an upper and lower double roller type, that is, there are two deburring rollers. By clamping the upper and lower double rollers, the cutting edge on the upper and lower surfaces of the casting billet is removed, thus improving the efficiency of deburring the casting billet.

[0020] 3. The blades on the deburring roller of this utility model are arranged in a complementary manner, which can effectively reduce the overall weight of the deburring roller and the centrifugal force during operation.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0030] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should be understood in their ordinary sense by one of ordinary skill in the art to which this utility model pertains.

The words “comprising” or “including” and similar terms mean that the element or object preceding “comprising” or “including” covers the element or object listed following “comprising” or “including” and its equivalents, and does not exclude other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections and can include electrical connections, whether direct or indirect. The singular forms “a,” “the,” and “the” used in this application specification and appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0031] Please refer to the following for details. Figure 1 A deburring device suitable for steel billets of different thicknesses includes a frame 1 and two sets of first drive devices. The frame 1 has a feed inlet, through which the billet enters and exits from the other side. Inside the frame 1 are two deburring rollers, including a first deburring roller 2 and a second deburring roller 3, which are distributed opposite each other with a gap between them. Both ends of the first deburring roller 2 and the second deburring roller 3 are located in sliding bearing covers 4, with one end connected to the first drive device. The first drive device includes a motor 13 and a universal coupling 14. One end of the universal coupling 14 is connected to the drive shaft of the motor 13, and the other end is connected to the first deburring roller 2 and the second deburring roller 3. Under the action of the motor 13, the first deburring roller 2 and the second deburring roller 3 can be driven to rotate in opposite directions through the universal coupling 14, thereby removing the cutting marks from the upper and lower surfaces of the billet's head and tail.

[0032] 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 first burr roller 2 and the second burr roller 3 respectively, so that the burrs on the upper and lower surfaces of the billet can be removed at the same time, thereby improving the efficiency of deburring the billet.

[0033] Please refer to the following for details. Figure 1 and 2The frame 1 is equipped with a second drive device 5 at both the top and bottom, and the second drive device 5 is connected to the sliding bearing cover 4. In this embodiment, the second drive device 5 is a hydraulic cylinder. The hydraulic cylinder on the frame 1 can drive the sliding bearing cover 4 (the first burr roller 2 and the second burr roller 3) to move towards or away from each other, that is, it can change the distance between the first burr roller 2 and the second burr roller 3 to adapt to casting billets of different thicknesses. Since the universal coupling 14 can transmit motion and torque, and has different degrees of axial, angular compensation and radial compensation, even if the drive shaft of the motor 13 is not on the same straight line as the first burr roller 2 and the second burr roller 3, it can still drive the first burr roller 2 and the second burr roller 3 to rotate.

[0034] Based on the above technical means: by changing the distance between the two burr rollers through the upper and lower second drive device 5 (oil cylinder), it is possible to adapt to casting billets of different thicknesses and achieve a permanent solution.

[0035] Please refer to the following for details. Figure 3 Four guide blocks 6 are provided on both sides of the frame 1. The guide blocks 6 are arranged in pairs facing each other, and a guide groove 7 is formed between the two opposing guide blocks 6. The sliding bearing cover 4 is located in the guide groove 7. A connecting cavity 12 is opened on the sliding bearing cover 4. One end of the output shaft of the second drive device 5 is located in the connecting cavity 12 and is fixed by fasteners. The guide blocks 6 and the guide groove 7 play a role in limiting and guiding, preventing the sliding bearing cover 4 from shifting its position during movement.

[0036] Please refer to the following for details. Figure 2 and 3 The guide block 6 has a waist-shaped hole 8. An adjustable component is located on the outer side of the guide block 6 on the right side. The adjustable component includes a fixing plate 9, two screws 10, and four nuts 11. The fixing plate 9 is fixed to the outer side of the guide block 6, and the screws 10 are mounted on the fixing plate 9. The fixing plate 9 has through holes for mounting the screws 10, and the diameter of the through holes is larger than the diameter of the screws 10. The fixing plate 9 is locked onto the screws 10 and is located on both sides of the fixing plate 9. The guide block 6 is fixed to the frame 1 by fasteners. Due to the design of the waist-shaped hole 8, the lateral position of the guide block 6 can be slightly adjusted. Combined with the adjustable component, the guide block 6 can be tightened. Specifically, when the position of the guide block 6 needs to be adjusted, first loosen the fasteners in the waist-shaped hole 8, then loosen the nuts 11, adjust the guide block 6, and after adjusting the position, tighten the fasteners again, and then press one end of the screw 10 against the guide block 6. Finally, tighten the nuts 11.

[0037] Please refer to the following for details. Figure 4The first burr roller 2 and the second burr roller 3 have the same structure. The first burr roller 2 and the second burr roller 3 include a roller body 15, two pressure plates 16, several pins 17 and several blades 18. Several spacers 19 are arranged along its axial direction and are alternately distributed. An installation space is formed between two adjacent spacers 19. The pressure plates 16 are located at both ends of the roller body 15. The pins 17 are inserted along the axial direction of the roller body 15 and fixed at both ends to the pressure plates 16. Several blades 18 are arranged in different installation spaces and are located on the pins 17.

[0038] Based on the above technical means, the blades 18 on the deburring roller are arranged in a complementary manner, which can effectively reduce the overall weight of the deburring roller and the centrifugal force during operation.

[0039] In this embodiment, several anchor bolts 20 are provided at the bottom of the frame 1 and the motor 13. The anchor bolts 20 are buried underground to ensure the stability of the device during operation.

[0040] In this embodiment, the bottom of the frame 1 is provided with an inclined material discharge chute 21 for the discharge of burrs.

[0041] In this embodiment, a hydraulic system is also included to control the operation of the second drive device 5. The hydraulic system uses a proportional valve to control the speed of the oil cylinder, and a frequency converter controls the rotation speed of the first burr roller 2 and the second burr roller 3, so as to achieve free control of the removal depth. The hydraulic system and the frequency converter are existing technologies, so they will not be described in detail.
