To the extent described in this section, the work of the presently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly admitted to be prior art to the present disclosure.

[0003] In the production of continuous casting thick slabs, a fire cutter is usually used to cut the continuous casting slabs into short slabs of a certain length for rolling by a rolling mill. However, after the cutting operation of the fire cutter, burrs will be formed at the bottom of the slab cut, and a deburring machine needs to be used to remove the burrs. The deburring machine used for continuous casting thick slabs is usually a hammer knife type slab deburring machine. The hammer knife used in the deburring machine includes a hammer knife group formed by multiple hammer knives of the same specification. In the actual burr treatment process, since the burrs on the slab are affected by many factors and the height of the burrs is different, all the hammer knives can only strike the burrs at one height and cannot effectively cover the entire burr height, resulting in unsatisfactory deburring effect. At the same time, the loss of the hammer knife is also very large, which affects the working efficiency and reduces the life of the grinding treatment system. Summary of the invention

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0034] like Figure 1 As shown, Figure 1 A burr treatment system provided in an embodiment of the present application is shown in a side view after assembly. The burr treatment system includes a spindle body 100, a constraint portion 200, a positioning portion 300, and an operating knife group 400, wherein:

[0035] The spindle body 100 is used to connect to the power part and rotate under the output of the power part. It should be noted that in order to improve the production rhythm, multiple spindle bodies 100 can be arranged in the production operation environment, and the multiple spindle bodies 100 can work in conjunction to improve the burr processing efficiency. It should be noted that a single spindle body 100 is used for expansion here, and multiple spindle bodies 100 only need to be stacked in number, and no further explanation is given.

[0036] The constraint parts 200 are provided in plurality and fixedly arranged on the spindle body 100 at intervals along the axial direction of the spindle body 100 . The plurality of constraint parts 200 are fixedly arranged on the spindle body 100 at intervals, and an assembly unit is formed between every two adjacent constraint parts 200 .

[0037] like Figure 1 , Figure 2 As shown, Figure 2 This is a partial cross-sectional view of the positioning portion 300 provided in an embodiment of the present application. The positioning portion 300 is provided in plurality and is arranged around the axial direction of the spindle body 100 on the outside of the spindle body 100. The positioning portion 300 passes through and is fixedly connected to the constraint portion 200. The plurality of positioning portions 300 pass through and are connected to the plurality of constraint portions 200, so that the plurality of positioning portions 300 fix the constraint portion 200 while providing an installation basis for the operating knife group 400 in each assembly unit. Furthermore, the plurality of positioning portions 300 are arranged at circumferential intervals on the outside of the spindle body 100, and the central axes of the positioning portions 300 are respectively parallel to the central axes of the spindle body 100. Thus, the plurality of positioning portions 300 provide a plurality of operating positions in the circumferential direction of the spindle body 100, thereby improving processing efficiency and making it easier to control the operating rhythm.

[0038] The working knife group 400 is provided in plurality and is respectively arranged on each of the positioning parts 300 between every two adjacent constraint parts 200. Each of the working knife groups 400 includes a plurality of working knife bodies 401 with the same thickness and different lengths. The working end of the working knife body 401 is higher than the edge of the constraint part 200. The working knife group 400 is provided in plurality and is respectively arranged between two constraint parts 200 on one of the positioning parts 300. Correspondingly, each of the working knife groups 400 includes a plurality of working knife bodies 401 with the same thickness and different lengths, so that the plurality of working knife bodies 401 on one of the positioning parts 300 include a plurality of different heights. Along with the operation of the main shaft body 100, the working knife bodies 401 of different lengths are rotated respectively to improve the operation reliability.

[0039] like Figure 1 , Figure 2 As shown, the lengths of the multiple working knife bodies 401 in each working knife group 400 are different. Taking the working knife group 400 as a unit, each working knife group 400 includes multiple working knife bodies 401, and further in each assembly unit, multiple working knife bodies 401 with different lengths are arranged to obtain different working heights in each assembly unit.

[0040] like Figure 1 , Figure 2As shown, the lengths of the plurality of working knife bodies 401 located at the same radial cross-sectional position of the positioning portion 300 are different. It should be emphasized that since there are a plurality of positioning portions 300, and the lengths of the plurality of working knife bodies 401 in each working knife group 400 on each positioning portion 300 are different, and the spindle body 100 drives the working knife body 401 to rotate by rotating, it is configured that the lengths of the plurality of working knife bodies 401 located at the same radial cross-sectional position of the positioning portion 300 are different, and thus during each rotation of the working knife body 401, in a single assembly unit, the plurality of positioning portions 30 0 The multiple working cutter bodies 401 at the same position rotate at the same plane position respectively, so that the multiple working cutter bodies 401 at the same radial cross-sectional position of the positioning part 300 operate on a relative position of the slab at the same time. If the lengths of the multiple working cutter bodies 401 at the same radial cross-sectional position of the positioning part 300 are different, the slab will be processed by working cutter bodies 401 of different lengths at this relative position, so that when burrs of different heights exist in this area of ​​the slab, grinding and cutting operations can be performed by the rotation of the spindle body 100 with working cutter bodies 401 of different lengths, correspondingly.

[0041] like Figure 1 , Figure 2 As shown, along with the dynamic operation process, each working knife group 400 covers the area to be processed of the slab in the length extension direction of the main shaft body 100. During the rotation process, the multiple working knife bodies 401 of different lengths in each working knife group 400 perform cyclic operation with different lengths each time they contact the slab, thereby improving the processing effect.

[0042] In an optional embodiment, the working principle of the burr processing system in the present application is: the burr processing system includes a main shaft body 100, a plurality of constraint parts 200, a plurality of positioning parts 300 and a plurality of working knife groups 400, the constraint parts 200 are fixedly arranged on the main shaft body 100 at intervals along the axial direction of the main shaft body 100, the positioning parts 300 are arranged outside the main shaft body 100 in the axial direction and in the circumferential direction around the main shaft body 100, the positioning parts 300 penetrate and are fixedly connected to the constraint parts 200, the working knife groups 400 are respectively arranged on each of the positioning parts 300 between every two adjacent constraint parts 200, each of the working knife groups 400 includes a plurality of working knife bodies 401 with the same thickness and different lengths, the working ends of the working knife bodies 401 are higher than the edges of the constraint parts 200, the lengths of the plurality of working knife bodies 401 in each of the working knife groups 400 are different, and are located at the same radial cross-sectional position of the positioning part 300 The lengths of the multiple working knife bodies 401 are different. By having different lengths of the multiple working knife bodies 401 in the multiple working knife groups 400 on the same positioning portion 300, the working ends of the multiple working knife groups 400 in the multiple working knife groups 400 on the multiple positioning portions 300 extend to different height positions, thereby processing burrs of different heights, improving the reliability of burr processing, and enhancing adaptability. Furthermore, by having different lengths of the multiple working knife bodies 401 located at the same radial cross-sectional position of the positioning portion 300, when the working knife group 400 follows the main shaft body 100 for rotational operation, at the same burr position, there are multiple working knife bodies 401 with different lengths for rotational processing operation, so that in the burr area, there are multiple working knife bodies 401 with different lengths for rotational operation, and the burr areas at different positions are staggered with working knife bodies 401 with different lengths, thereby improving processing efficiency, reducing unnecessary single wear, and increasing service life.

[0043] In an optional embodiment, the number of the working knife bodies 401 in each of the working knife groups 400, the number of the positioning portions 300, and the number of the working knife groups 400 on one of the positioning portions 300 are the same, and the length values ​​of the multiple working knife bodies 401 in each of the working knife groups 400 are in an arithmetic progression, which is convenient for arrangement. They can be evenly arranged in the length direction and circumferential direction of the main shaft body 100, respectively, so that different working knife bodies 401 can be more evenly matched in the length direction and circumferential direction of the main shaft body 100, thereby improving the working effect, taking into account the wear rate of multiple working knife bodies 401 of different sizes, and extending the overall service life.

[0044] like Figure 1 , Figure 3 As shown, Figure 3A schematic diagram of a partial working blade 401 on a first positioning portion 300 provided in an embodiment of the present application. In an optional embodiment, the working blade group 400 includes working blades 401 whose lengths decrease successively: D1, D2, D3...Dn, n is the number of the working blades 401 in each working blade group 400, and along the length extension direction of the positioning portion 300, on the first positioning portion 300, the working blades 401 of the n working blade groups 400 are arranged as: D1, D2, D3...Dn; D2, D3...Dn, D1; D3...Dn, D1, D2; Dn...D1, D2, D3.

[0045] Among the multiple positioning parts 300, one is selected as the first positioning part 300, and the n working blades 401 in the working blade group 400 are numbered in sequence by length: D1, D2, D3...Dn, D1 is the longest, and Dn is the shortest working blade 401, and the working blades 401 in each working blade group 400 on the first positioning part 300 are arranged respectively.

[0046] For ease of explanation, an example is taken in which the working knife group 400 is provided with six working knife bodies 401 of different lengths, and the six working knife bodies 401 are marked in descending order of length: D1, D2, D3, D4, D5, D6.

[0047] like Figure 3 , Figure 3 A schematic diagram of a part of the working blade body 401 on the first positioning portion 300 provided in an embodiment of the present application, and, on the first positioning portion 300, six transfer units are formed by six constraint portions 200, six working blade groups 400 are respectively arranged in the six transfer units, and all the working blade bodies 401 are arranged in the order of: D1, D2, D3, D4, D5, D6;

[0048] D2, D3, D4, D5, D6, D1; D3, D4, D5, D6, D1, D2; D4, D5, D6, D1, D2, D3; D5, D6, D1, D2, D3, D4; D6, D1, D2, D3, D4, D5.

[0049] like Figure 3 , Figure 4 As shown, Figure 4A schematic diagram of a part of the working blade 401 on the second positioning portion 300 provided in an embodiment of the present application. In an optional embodiment, around the circumference of the spindle body 100, along the length extension direction of the positioning portion 300, on the second positioning portion 300 adjacent to the first positioning portion 300, the working blades 401 of the n working blade groups 400 are arranged as follows: D2, D3 ... Dn, D1; D3 ... Dn, D1, D2; Dn ... D1, D2, D3; L1, L2, L3 ... Ln, and the second positioning portion 300 is adjacent to the first positioning portion 300. On the third positioning portion 300 adjacent to the positioning portion 300, the working blades 401 of the n working blade groups 400 are arranged as: D3...Dn, D1, D2; Dn...D1, D2, D3; L1, L2, L3...Ln; D2, D3...Dn, D1, and on the nth positioning portion 300, the working blades 401 of the n working blade groups 400 are arranged as: Dn...D1, D2, D3; L1, L2, L3...Ln; D2, D3...Dn, D1, D3...Dn, D1, D2.

[0050] With this arrangement, it can be effectively achieved that: at the same radial cross-sectional position of the positioning portion 300, a complete working knife body 401 of each corresponding length size in the working knife set 400 is arranged clockwise or counterclockwise.

[0051] That is to say, in the length direction of the positioning part 300, the first working blade 401 on all the positioning parts 300 includes D1, D2, D3...Dn of different lengths in sequence, and the second working blade 401 on all the positioning parts 300 also includes D1, D2, D3...Dn of different lengths in sequence.

[0052] For further explanation, the multiple working blades 401 located at the same radial cross-sectional position of the positioning portion 300 are regarded as an annular blade group, and each annular blade group includes working blades 401 with successively decreasing lengths: D1, D2, D3...Dn, and each annular blade group is staggered with the adjacent annular blade group, that is, the annular blades of different lengths in the adjacent annular blade groups correspond to each other.

[0053] For ease of explanation, the above-mentioned working knife group 400 is still taken as an example in which the six working knife bodies 401 of different lengths are set, and the six working knife bodies 401 are marked in descending order of length: D1, D2, D3, D4, D5, D6.

[0054] like Figure 1 , Figure 4As shown, on this basis, taking the clockwise direction of the circumference of the spindle body 100 as an example, and selecting an adjacent positioning portion 300 in the clockwise direction as the second positioning portion 300, the arrangement order of all the working blades 401 on the second positioning portion 300 is determined to be: D2, D3, D4, D5, D6, D1; D3, D4, D5, D6, D1, D2; D4, D5, D6, D1, D2, D3; D5, D6, D1, D2, D3, D4; D6, D1, D2, D3, D4, D5; D1, D2, D3, D4, D5, D6.

[0055] Correspondingly, on this basis, a positioning portion 300 adjacent to the second positioning portion 300 in the clockwise direction on the circumference of the spindle body 100 is still used as the third positioning portion 300, and the arrangement order of all the working blades 401 on the third positioning portion 300 is determined as follows: D3, D4, D5, D6, D1, D2; D4, D5, D6, D1, D2, D3; D5, D6, D1, D2, D3, D4; D6, D1, D2, D3, D4, D5; D1, D2, D3, D4, D5, D6; D2, D3, D4, D5, D6, D1.

[0056] Correspondingly, on this basis, a positioning portion 300 adjacent to the third positioning portion 300 in the clockwise direction on the circumference of the main shaft body 100 is still used as the fourth positioning portion 300, and the arrangement order of all the working knife bodies 401 on the fourth positioning portion 300 is determined as follows: D4, D5, D6, D1, D2, D3; D5, D6, D1, D2, D3, D4; D6, D1, D2, D3, D4, D5; D1, D2, D3, D4, D5, D6; D2, D3, D4, D5, D6, D1; D3, D4, D5, D6, D1, D2.

[0057] Correspondingly, on this basis, a positioning portion 300 adjacent to the fourth positioning portion 300 in the clockwise direction on the circumference of the spindle body 100 is still used as the fifth positioning portion 300, and the arrangement order of all the working knife bodies 401 on the fifth positioning portion 300 is determined as follows: D5, D6, D1, D2, D3, D4; D6, D1, D2, D3, D4, D5; D1, D2, D3, D4, D5, D6; D2, D3, D4, D5, D6, D1; D3, D4, D5, D6, D1, D2; D4, D5, D6, D1, D2, D3.

[0058] Correspondingly, on this basis, a positioning portion 300 adjacent to the fifth positioning portion 300 in the clockwise direction on the circumference of the main shaft body 100 is still used as the sixth positioning portion 300, and the arrangement order of all the working knife bodies 401 on the sixth positioning portion 300 is further determined as: D6, D1, D2, D3, D4, D5; D1, D2, D3, D4, D5, D6; D2, D3, D4, D5, D6, D1; D3, D4, D5, D6, D1, D2; D4, D5, D6, D1, D2, D3; D5, D6, D1, D2, D3, D4.

[0059] In an optional embodiment, each of the working blades 401 is arranged in parallel with the constraint portion 200 to maintain the stability of burr processing.

[0060] In an optional embodiment, an assembly gap 502 is provided between each adjacent working blade 401 to facilitate heat dissipation and debris discharge.

[0061] In an optional embodiment, the distance between each of the working cutter bodies 401 and the main shaft body 100 is the same, so that the height of the working end of the working cutter body 401 can be stably controlled by the length of the working cutter body 401 .

[0062] In an optional embodiment, each of the working cutter bodies 401 is provided with mounting holes 501 of the same size, and the distances from the center lines of the mounting holes 501 to the spindle body 100 are the same, so as to maintain the smoothness of the assembly of the working cutter body 401 while further maintaining the working cutter body 401.

[0063] In an optional embodiment, the mounting through hole 501 is a strip hole, and the working cutter body 401 can reciprocate radially along the main shaft body 100 on the positioning portion 300. When working at the working end of the working cutter body 401, the working cutter body 401 and the positioning portion 300 can move relative to each other to adaptively provide a movable margin and protect the integrity of the working cutter body 401. When faced with burrs of certain special shapes or thicknesses, the burrs can be avoided by the displacement of a single working cutter body 401, and the burrs can be removed together with the subsequent cutting operations of multiple working cutter bodies 401, thereby improving the overall reliability and service life.

[0064] like Figure 1 As shown, based on the same inventive concept, the present application also provides an assembly method of a burr treatment system, the assembly method is applied to the burr treatment system as described above, and the assembly method includes:

[0065] In the working blade set 400, the working blade body 401 with a middle length value is selected as the control blade body;

[0066] On the slab roller table 601, a reference portion 602 is arranged horizontally;

[0067] Rotate the spindle body 100 and arrange the reference blade body toward the reference portion 602;

[0068] The height of the spindle body 100 is adjusted until the working end of the reference blade body is tangent to the bottom surface of the reference portion 602 to complete the assembly.

[0069] Among the working cutter bodies 401 with multiple length values ​​in the working cutter group 400, by using the working cutter body 401 with the middle length value as a reference, the longer or shorter working cutter body 401 can more stably cover the burr range, so as to ensure that the working cutter group 400 can effectively process the burrs during the rotating operation, thereby improving the working efficiency and processing effect.
