Description

Technical Field

[0001] This utility model relates to the field of high alloy intermediate billet rolling technology, specifically to a groove device for assisting intermediate billet rolling. Background Technology

[0002] Intermediate billets (mainly φ60mm round) formed during high alloy rolling need to be reused to improve yield. The intermediate billets need to be cut into small sections of about 3 meters for re-rolling. Since the distance between the flying shear and the finishing mill is greater than 3 meters, and the cut billets are small, the impact force is insufficient, causing the billets to be unable to be properly bitten into the finishing mill. The billets need to be manually dragged and pulled to the finishing mill, which takes a long time and causes the surface temperature of the billets to drop, making it impossible to continue rolling, resulting in low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a groove device for assisting in the rolling of intermediate billets, so as to solve the technical problems in the background art mentioned above.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grooving device for assisting in the rolling of intermediate billets. The grooving device is applied in an intermediate billet rolling production line, which includes a conveyor roller table, a flying shear, and a finishing mill. The grooving device can carry the intermediate billet and drive it to the finishing mill via the conveyor roller table for rolling. The grooving device includes a bracket and a top feed frame, wherein the bracket is connected to the top feed frame. A grooving adapted to the intermediate billet is provided in the bracket. Along the conveying direction of the conveyor roller table, the grooving slot faces the finishing mill. The intermediate billet can be placed in the grooving slot and abuts against a limiting mechanism provided on the top feed frame along the axial direction of the bracket. When the intermediate billet reaches the finishing mill, the grooving device is supported by the flying shear platform. The end of the bracket away from the top feed frame is located between the flying shear and the finishing mill, and the end of the top feed frame away from the bracket is located on the conveyor roller table.

[0005] Based on the above technical features, the intermediate billet support device of this utility model can carry intermediate billets and directly send them to the finishing mill for rolling via a conveyor roller conveyor. After the intermediate billet bites into the finishing mill, the conveyor roller conveyor reverses, and the support device can automatically return to its original position for the next round of intermediate billet transport. In this process, the intermediate billet only needs to be placed in the support slot, and it can be transported to the finishing mill for finishing rolling with the support device. No manual dragging or pulling intervention is required, reducing the labor intensity on site. At the same time, the smooth transport process of the intermediate billet effectively reduces the risk of rolling failure due to the decrease in surface temperature of the intermediate billet, and significantly improves the rolling yield of intermediate billets.

[0006] Preferably, in this technical solution, the bracket is U-shaped, and its length is the same as the length of the groove along the conveying direction of the conveying roller conveyor; the bracket is a hollow rectangular frame with a top opening. More preferably, the intermediate blank has a length of 3000mm and a cross-sectional diameter of 60mm; the groove has a length of 2000mm to 2500mm, a width of 65mm to 70mm, and a depth of 45mm to 55mm.

[0007] Based on the above technical features, the U-shaped cross-section design of the bracket can effectively fix the position of the intermediate blank and prevent it from shifting and slipping during transportation.

[0008] Preferably, in this technical solution, the top-feeding frame is a rectangular frame, and a top plate is provided at one end of the top-feeding frame connected to the bracket, with the top serving as the limiting mechanism; when the intermediate billet is placed in the tray and moves along the conveyor rollers, the intermediate billet abuts against the top plate. More preferably, the rectangular cross-sectional width of the top-feeding frame is the same as the width of the bracket; the length of the top-feeding frame is 2000mm to 3000mm, and the rectangular cross-sectional width of the top-feeding frame is 65mm to 70mm.

[0009] Based on the above technical features, the overall length of the slotting device is greater than 4 meters, which ensures that the billet placed in the slot can pass smoothly through the 3.5-meter suspended section between the flying shear and the finishing mill, and be transported to the finishing mill for rolling.

[0010] Preferably, in this technical solution, the top-feeding frame is a four-sided trapezoidal frame. The rectangular end face of the top-feeding frame connected to the bracket is smaller than the rectangular end face of the other end away from the bracket, and a top plate is provided at one end of the top-feeding frame connected to the bracket. When the intermediate billet is placed in the tray and moves through the conveyor rollers, the intermediate billet abuts against the top plate. More preferably, the width of the end face of the top-feeding frame connected to the bracket is the same as the width of the bracket; the length of the top-feeding frame is 2000mm to 3000mm.

[0011] Based on the above technical features, the top feed frame is set in the shape of a four-sided trapezoidal truncated platform, which effectively avoids the overturning of the trough device during the conveying process. At the same time, it also makes the weight of the top feed frame much greater than the weight of the support frame that carries the intermediate billet. When the intermediate billet is conveyed to the finishing mill, the heavy top feed frame can provide the intermediate billet with a large inertial force, which makes it easier for the intermediate billet to be bitten by the finishing mill. This avoids the trouble of having to manually drag and pull the billet if it is not bitten incompletely.

[0012] In this technical solution, preferably, the bottom surfaces of the bracket, the top feed frame, and the conveyor rollers that come into contact with each other are polished.

[0013] Based on the above technical features, the frictional loss between the troughing device and the conveying roller can be significantly reduced, extending the service life of the equipment. At the same time, it also makes the conveying of intermediate billets carried in the trough smoother, shortens the time consumption, and effectively reduces the risk of rolling failure due to the decrease in surface temperature of intermediate billets.

[0014] In this technical solution, preferably, both the bracket and the jacking frame are rectangular steel pipes, and the bracket and the jacking frame are detachably connected.

[0015] Based on the above technical features, the bracket can be flexibly replaced according to the cross-sectional diameter of the intermediate blank, which improves the applicability of the bracket device.

[0016] Preferably, in this technical solution, the end of the bracket away from the top feed frame has an inclined cutting surface, and the inclined cutting surface forms an angle of 40° to 50° with the vertical direction.

[0017] Based on the above technical features, the inclined cutting surface set on the bracket can effectively assist in the precise positioning of the intermediate billet, enabling the intermediate billet to be quickly placed into the tray and improving transportation efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0031] like Figures 1 to 8 As shown, this utility model provides a technical solution: a grooving device for assisting in the rolling of intermediate billets. The grooving device 6 is applied in an intermediate billet rolling production line. The rolling production line includes a conveyor roller table 1, a flying shear 2, a finishing mill 3, and a roughing mill 4. The grooving device 6 can carry the intermediate billet 5 and drive it to the finishing mill 3 for rolling via the conveyor roller table 1. The grooving device 6 includes a bracket 61 and a top feed frame 62.

[0032] Specifically, the bracket 61 is connected to the top feed frame 62. The bracket 61 has a groove 61A that is adapted to the intermediate billet 5. Along the conveying direction of the conveying roller table 1, the groove 61A faces the finishing mill 3. The intermediate billet 5 can be placed in the groove 61A and abut against the limiting mechanism provided on the top feed frame 62 along the axial direction of the bracket 61.

[0033] like Figure 1The diagram shows the intermediate billet 5 arriving at the finishing mill 3 in preparation for bite-in finishing. When the intermediate billet 5 arrives at the finishing mill 3, the grooving device 6 is supported on the flying shear 2 platform. The end of the bracket 61 away from the top feed frame 62 is located between the flying shear 2 and the finishing mill 3, and the end of the top feed frame 62 away from the bracket 61 is located on the conveying roller table 1.

[0034] The intermediate billet 5, transferred from the roughing mill 4, is manually placed onto the grooving device. The conveyor roller 1 then rotates forward, transporting the grooving device and the intermediate billet 5 to the finishing mill 3. After the intermediate billet 3 is bitten into the finishing mill 3, the conveyor roller 1 reverses direction, and the grooving device returns to its original position for the next round of intermediate billet 5 transport. In this process, the intermediate billet 5 only needs to be placed into the grooving slot 61A, and it will be transported to the finishing mill 3 for finishing rolling without manual dragging or pulling, reducing on-site labor intensity. Simultaneously, the smooth transport process of the intermediate billet 5 effectively reduces the risk of rolling failure due to a drop in surface temperature, significantly improving the rolling yield of the intermediate billet 5.

[0035] Furthermore, the bracket 61 is U-shaped and its length is the same as the length of the trough 61A along the conveying direction of the conveyor roller 1. The bracket 61 is a hollow rectangular frame with a top opening. The U-shaped cross-section design of the bracket 61 can effectively fix the position of the intermediate blank 5, preventing it from shifting and slipping during the conveying process, thereby reducing manual intervention on the intermediate blank 5 and realizing automated processing.

[0036] Taking intermediate blank 5 with a length of 3000mm and a cross-sectional diameter of 60mm as an example:

[0037] In this utility model, the length of the bracket 61A is 2000mm to 2500mm, and the specific length of the bracket 61A can be selected as 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, or any value between two adjacent values. The width of the bracket 61A is 65mm to 70mm, and the specific width of the bracket 61A can be selected as 65mm, 66mm, 67mm, 68mm, 69mm, 70mm, or any value between two adjacent values. The depth of the bracket 61A is 45mm to 55mm, and the specific depth of the bracket 61A can be selected as 45mm, 46mm, 47mm, 48mm, 49mm, 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, or any value between two adjacent values. The length of the top feed frame 62 can be selected from 2000mm to 3000mm. The specific length of the top feed frame 62 can be 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, 2600mm, 2700mm, 2800mm, 2900mm, 3000mm, or any value between two adjacent values. In this utility model, the overall length of the slotting device is greater than 4 meters, ensuring that the intermediate billet 5 placed in the slot 61A can smoothly pass through the 3.5-meter suspended section between the flying shear 2 and the finishing mill 3, and be transported to the finishing mill 3 for rolling.

[0038] like Figures 2 to 5 The diagram shown is a schematic diagram and three views of the bracket device in the first embodiment of this utility model. In the first embodiment shown:

[0039] The top feed frame 62 is a rectangular frame, and a top plate 7 is provided at one end of the top feed frame 62 that is connected to the bracket 61. The top plate 7 is the aforementioned limiting mechanism. When the intermediate billet 5 is placed in the tray 61A and moves through the conveyor roller 1, the intermediate billet 5 abuts against the top plate 7.

[0040] Preferably, the bracket 61 and the top feed frame 62 are welded at their connection point, and a steel plate 7 is welded above the weld point. The width of the welded steel plate 7 is the same as the width of the groove 61A. The intermediate billet 5 is placed in the groove 61A and conveyed by the conveyor roller 1, allowing it to smoothly enter the finishing mill 3 for finishing rolling. The groove device formed by the welded bracket 61 and the top feed frame 62 can move freely back and forth on the conveyor roller 1. The rectangular cross-sectional width of the top feed frame 62 is the same as the width of the bracket 61. The length of the top feed frame 62 is 2000mm to 3000mm, and the rectangular cross-sectional width of the top feed frame 62 is 65mm to 70mm. Specifically, the rectangular cross-sectional width can be selected as 65mm, 66mm, 67mm, 68mm, 69mm, 70mm, or any value between two adjacent values.

[0041] like Figures 6 to 8The image shown is a three-view drawing of the bracket device in the second embodiment of this utility model. In the second embodiment shown:

[0042] The top feed frame 62 is a four-sided trapezoidal frame. The rectangular end face of the top feed frame 62 connected to the bracket 61 is smaller than the rectangular end face of the other end away from the bracket 61, and a top plate 7 is provided at one end of the top feed frame 62 connected to the bracket 61. When the intermediate billet 5 is placed in the groove 61A and moves through the conveyor roller 1, the intermediate billet 5 abuts against the top plate 7.

[0043] Preferably, the width of the end face of the top feed frame 62 connected to the bracket 61 is the same as the width of the bracket 61, and the length of the top feed frame 62 is 2000mm to 3000mm. In the second embodiment shown, the top feed frame 62 is set in the shape of a four-sided trapezoidal truncated pyramid, which effectively avoids the overturning of the tray device during the conveying process. At the same time, it also makes the weight of the top feed frame 62 much greater than the weight of the bracket 61 that carries the intermediate billet 5. When the intermediate billet 5 is conveyed to the finishing mill 3, the heavy top feed frame 62 can provide the intermediate billet 5 with a large inertial force, which makes it easier for the intermediate billet 5 to be bitten by the finishing mill 3, avoiding the trouble of manual dragging and pulling when the biting is incomplete.

[0044] In the first and second embodiments shown above, the bottom surfaces of the bracket 61, the top feed frame 62 and the conveying rollers that come into contact with each other can be polished to reduce frictional loss between the tray device and the conveying rollers 1, extend the service life of the equipment, and at the same time make the intermediate billet 5 carried in the tray 61A more smoothly conveyed, effectively reducing the risk of rolling failure due to the decrease in surface temperature of the intermediate billet 5.

[0045] Preferably, in order to flexibly replace the bracket 61 according to the cross-sectional diameter of the intermediate billet 5 and improve the applicability of the support device, both the bracket 61 and the top-feeding frame 62 can be selected as rectangular steel pipes, and the bracket 61 and the top-feeding frame 62 are connected in a detachable manner. Specifically, in actual operation, the bracket 61 can extend into the frame of the top-feeding frame 62, and be fixed with bolts and nuts in the overlapping areas where they intersect.

[0046] Furthermore, the end of the bracket 61 furthest from the top feed frame 62 has an inclined cutting surface 61B, which forms an angle of 40° to 50° with the vertical direction. The specific angle can be 40°, 42°, 44°, 46°, 48°, 50°, or any value between two angles. The inclined cutting surface 61B effectively assists in the precise positioning of the intermediate billet 5, allowing it to be quickly placed into the tray 61A, thus improving billet transport efficiency.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
