Description

Technical Field

[0001] This utility model relates to the technical field of metal rolling auxiliary equipment, specifically a new type of cold rolling mill residual coil processing equipment. Background Technology

[0002] Cold rolling mills, as core equipment in metal sheet and strip processing, are widely used in the medium and fine rolling and finished product production of materials such as carbon steel, alloy steel, copper, aluminum, and stainless steel. They achieve high-efficiency processing due to their advantages of high rolling precision, high speed, and stable tension. The essence of the process is to compress the metal billet using rotating rolls, reducing the cross-section while extending the length. In aluminum coil rolling, the cylindrical sleeve performs the function of coil winding. However, when aluminum alloys are rolled from thick to thin, due to process limitations, the end of the coil tightly attached to the sleeve cannot be used for finished product production due to uneven thickness, forming discarded "residual coils." These residual coils attached to the sleeve not only occupy storage space but also waste metal resources.

[0003] The authorized announcement number is CN217251674U, which discloses a device for handling residual coils from an aluminum alloy rolling mill. This device uses a hydraulic cylinder to drive a moving plate that adjusts back and forth to accommodate the pushing stroke, and uses a hydraulic cylinder to control the height of a pressure plate to support the weight of the coil, assisting in the removal of the residual coil from the expansion and contraction reel. Simultaneously, a double-opening reel with a stop shaft prevents coil deviation, thus initially achieving the function of uncoiling the residual coil. However, this device has significant limitations: firstly, after the residual coil is transferred from the sleeve to the expansion and contraction reel, manual assistance is still required for uncoiling, and the removed residual coil is bulky and difficult to transport directly; secondly, the key process of automatic uncoiling, directional feeding, and compaction into blocks is not integrated, resulting in low processing efficiency and high transportation costs, failing to meet the automation requirements of modern production.

[0004] Based on this, a new type of cold rolling mill waste coil processing equipment is now provided, which can eliminate the drawbacks of existing equipment. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] In one embodiment, such as Figures 1-2 As shown, a novel cold rolling mill waste coil processing device includes a sleeve pick-and-place platform 11 and a mounting base 39. The sleeve pick-and-place platform 11 is slidably mounted on one end of the mounting base 39. The upper end of the sleeve pick-and-place platform 11 is provided with a placement groove.

The upper end of the mounting base 39 is provided with a rotating component, a conveying component, and a pressing component in sequence along the moving direction of the waste coil 31. The rotating component includes two symmetrically arranged clamping discs 37. The upper end of the sleeve pick-and-place platform 11 is provided with a displacement mechanism and a rotating mechanism for driving the clamping discs 37 to move and rotate. The rotating component facilitates the clamping and fixing of the sleeve body 38, and at the same time drives the sleeve body 38 to rotate, thereby unfolding the waste coil 31. The conveying component facilitates the conveying of the waste coil 31. The pressing component facilitates the compression of the collected waste coil 31 into blocks. The displacement mechanism includes a seventh hydraulic cylinder 34. A fixed shaft is fixedly provided on one side of the clamping plate 37. A bearing is provided on the fixed shaft. The bearing is fixedly provided in the mounting groove on one side of the sliding block. The sliding block is slidably provided inside the fixed tube. A first fixed plate is fixedly provided on the fixed tube. The first fixed plate is fixedly provided on the upper end of the sleeve pick-and-place platform 11.

A rotating plate is rotatably mounted on the internal spline shaft. The other end of the rotating plate is rotatably connected to the fixed shaft. In use, when the sleeve pick-and-place platform 11 needs to receive the sleeve body 38 from the uncoiling end of the cold rolling mill, the output end of the second hydraulic cylinder 17 extends, causing the second hydraulic cylinder 17 to push the sleeve pick-and-place platform 11 to move. The sleeve body 38 falls onto the upper end of the sleeve pick-and-place platform 11 at the end of the mounting base 39. Then, the output end of the second hydraulic cylinder 17 pulls the sleeve pick-and-place platform 11 to move between the two clamping discs 37. Then, the output end of the seventh hydraulic cylinder 34 drives the sliding block to slide, so that the two sliding blocks drive the clamping discs 37 to move through the fixed shaft. The fixed shaft drives the drive gear 36 to move through the rotating plate. When the two clamping discs 37 are in close contact with the two ends of the sleeve body 38, the clamping discs 37 stop moving. Then, the output end of the third reduction motor 35 drives the drive gear 36 to rotate. The drive gear 36 meshes with the driven gear, so that the sleeve body 38 rotates, thereby unfolding the residual roll 31 on the sleeve body 38.

[0020] The conveying component includes a second pinch roller 18 and a third pinch roller 25. The second pinch roller 18 is rotatably mounted inside the mounting base 39, and the third pinch roller 25 is rotatably mounted on the upper end of the extrusion seat 24.

A first guide plate 16 is fixedly mounted on the inner side of the mounting base 39 at a position corresponding to one side of the second pinch roller 18. A second guide plate 20 is fixedly mounted on the inner side of the mounting base 39 at a position corresponding to the position between the second pinch roller 18 and the third pinch roller 25. In use, when it is necessary to convey the residual roll 31... The head of the scrap roll 31 moves between the first pinch roller 15 and the second pinch roller 18. Then, the output end of the third cylinder 21 retracts, causing the first pinch roller 15 and the second pinch roller 18 to clamp the scrap roll 31. Then, the output end of the first reduction motor 19 drives the second pinch roller 18 to rotate, thereby conveying the scrap roll 31. Then, the head of the scrap roll 31 moves between the third pinch roller 25 and the fourth pinch roller 29. The output end of the fourth cylinder 22 drives the second pinch swing arm 28 to rotate, causing the third pinch roller 25 and the fourth pinch roller 29 to clamp the scrap roll 31. At the same time, the output end of the second reduction motor 26 drives the fourth pinch roller 29 to rotate through the drive chain 27, thereby conveying the scrap roll 31. Then, the scrap roll 31 falls into the material cavity 30 for collection.

[0022] The pressing component includes a material chamber door 32, one end of which is slidably provided with a fixed seat. The fixed seat is fixedly mounted on one end of the mounting base 39. The material chamber door 32 is fixedly mounted on the output end of the sixth hydraulic cylinder 33, which is fixedly mounted on the fixed seat. The extrusion seat 24 is fixedly mounted on the output end of the fifth hydraulic cylinder 23, which is fixedly mounted inside the mounting base 39. In use, when it is necessary to extrude the residual roll 31 inside the material chamber 30, the output end of the sixth hydraulic cylinder 33 drives the material chamber door 32 to descend, so that the bottom end of the material chamber door 32 is in close contact with the upper end of the third pinch roller 25. Then, the output end of the fifth hydraulic cylinder 23 drives the extrusion seat 24 to slide, thereby extruding and forming the residual roll 31.

The guide rod swing arms 12 are hinged to the upper end of the mounting base 39. A first hydraulic cylinder 13 is hinged to one side of the guide rod swing arms 12. The first hydraulic cylinder 13 is hinged to the upper end of the mounting base 39. In use, if the thickness of the residual roll 31 is relatively thick, the material head will be severely tilted. In this case, the guide rod is needed to assist in pressing the material head down so that it can enter between the first pinch roller 15 and the second pinch roller 18.

[0024] The above embodiment discloses a novel cold rolling mill residual coil processing device. When the sleeve pick-and-place platform 11 needs to receive the sleeve body 38 from the uncoiling end of the cold rolling mill, the output end of the second hydraulic cylinder 17 extends, causing the second hydraulic cylinder 17 to push the sleeve pick-and-place platform 11 to the end of the mounting base 39, causing the sleeve body 38 to fall onto the upper end of the sleeve pick-and-place platform 11. Then, the output end of the second hydraulic cylinder 17 pulls the sleeve pick-and-place platform 11 to move between two clamping discs 37. Subsequently, the output end of the seventh hydraulic cylinder 34 drives the sliding blocks to slide, causing the two sliding blocks to drive the clamping discs 37 to move via a fixed shaft. The fixed shaft drives the drive gear 36 to move via a rotating plate. When the two clamping discs 37 are tightly attached to both ends of the sleeve body 38, the clamping discs 37 stop moving. Then, the output end of the third reduction motor 35 drives the drive gear 36 to rotate. The drive gear 36 meshes with the driven gear, causing the sleeve body to rotate. Rotating 38 unfolds the residual roll 31 on the sleeve body 38. When the residual roll 31 needs to be conveyed, the head of the residual roll 31 moves between the first pinch roller 15 and the second pinch roller 18. Then, the output end of the third cylinder 21 retracts, so that the first pinch roller 15 and the second pinch roller 18 clamp the residual roll 31. Then, the output end of the first reduction motor 19 drives the second pinch roller 18 to rotate, so that the residual roll 31 is conveyed. Then, the head of the residual roll 31 moves between the third pinch roller 25 and the fourth pinch roller 29. The output end of the fourth cylinder 22 drives the second pinch swing arm 28 to rotate, so that the third pinch roller 25 and the fourth pinch roller 29 clamp the residual roll 31. At the same time, the output end of the second reduction motor 26 drives the fourth pinch roller 29 to rotate through the drive chain 27, so that the residual roll 31 is conveyed. Then, the residual roll 31 falls into the material cavity 30 for collection. When it is necessary to extrude the roll 31 inside the material cavity 30, the output end of the sixth hydraulic cylinder 33 drives the material cavity door 32 to descend, so that the bottom end of the material cavity door 32 is in close contact with the upper end of the third pinch roller 25. Then, the output end of the fifth hydraulic cylinder 23 drives the extrusion seat 24 to slide, thereby extruding and forming the roll 31. If the roll 31 is thick, the material head will be severely tilted upwards, and a guide rod is needed to assist in pressing the material head down so that it can enter between the first pinch roller 15 and the second pinch roller 18. The above description is only a specific embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
