Description

Technical Field

[0001] The present invention belongs to the technical field of production and processing of alloy materials. Specifically, it relates to a processing system for rare earth nickel-based strip materials. Background Art

[0002] Currently, after hot rolling of strip materials, it is necessary to cool the strip materials by water spraying so that the temperature of the strip materials drops to a predetermined temperature. Generally, it needs to be cooled to room temperature to facilitate the smooth progress of subsequent cold rolling processes. During the cooling process, since the strip materials pass through the cooling water spraying device in a straight line form, usually, in order to make the strip materials reach the predetermined temperature, a sufficiently long cooling line is required to achieve the purpose of cooling. In addition, existing cold rolling generally can only cold roll one strip material at a time, and its efficiency is low. When strip materials of different thicknesses are required, multiple sets of cold rolling equipment are needed, or when producing strip materials of another thickness, it is necessary to adjust the vertical spacing of the cold rolling rolls of the cold rolling equipment so as to adapt to cold rolling production of strip materials of the corresponding thickness. In this way, manual adjustment is required, the operation steps are complicated, and the efficiency is low, and the production of multiple strip materials of different thicknesses cannot be completed synchronously. Summary of the Invention

[0015] Due to the adoption of the above structure, the technical progress achieved by the present invention compared with the prior art is as follows: The strip is cut into multiple strip segments before entering the cooling spray mechanism. Since the strip has a relatively high temperature and is relatively soft in texture, it is convenient for the cutting operation. These strip segments enter the undulating adjustable conveying mechanism side by side. The undulating adjustable conveying mechanism adjusts the strip segments in a horizontal state into an undulating form. In this way, within a cooling line of a predetermined length, longer strip segments can be accommodated. These strip segments are cooled by the cooling water sprayed by the cooling spray mechanism, so that the strip segments can be sufficiently cooled. When the strip segments are led out of the cooling spray mechanism, their temperature is reduced to the expected value. Then, the side-by-side strip segments enter the different-thickness synchronous cold rolling mechanism synchronously. The different-thickness synchronous cold rolling mechanism performs synchronous cold rolling on these strip segments, and the thicknesses of these strip segments after cold rolling are different. Since the thicknesses of these strip segments after cold rolling are different, in order to avoid the situation of partial strip segments becoming slack, a tensioning mechanism is used to tension the slack strip segments. And in order to avoid the situation of adjacent strip segments shifting or intersecting, a limiting mechanism separates the adjacent strip segments from each other. The strip segments after cold rolling are wound into a roll by a winding roller. In summary, it can be seen that the present invention effectively shortens the length of the strip cooling line, saves space, improves the cooling efficiency, and can simultaneously carry out the production operation of strips with different thicknesses, thereby enhancing the production efficiency.

Detailed implementation mode

[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0040] The present invention discloses a rare - earth nickel - based strip processing system, as Figures 1 - 20As shown in the figure, it includes a lifting adjustable conveying mechanism, a different-thickness synchronous cold rolling mechanism 1000, a cooling spray mechanism 700, a plurality of limiting mechanisms 1100 and a plurality of tensioning mechanisms 1200. Among them, the lifting adjustable conveying mechanism and the different-thickness synchronous cold rolling mechanism 1000 are arranged in sequence along the conveying direction of the strip. The cooling spray mechanism 700 is arranged above the lifting adjustable conveying mechanism and is used to cool the strip or strip 800 passing through the lifting adjustable conveying mechanism. The plurality of limiting mechanisms 1100 and the plurality of tensioning mechanisms 1200 of the present invention are arranged at intervals on the different-thickness synchronous cold rolling mechanism 1000 along the movement direction of the strip. The strip after hot rolling is divided into a plurality of strips 800. These strips 800 pass side by side through the lifting adjustable conveying mechanism, and after being cooled by the cooling spray mechanism 700, they enter the different-thickness synchronous cold rolling mechanism 1000, and the different-thickness synchronous cold rolling mechanism 1000 performs synchronous cold rolling on these strips 800. The working principle and advantages of the present invention are as follows: The strip is cut into a plurality of strips 800 before entering the cooling spray mechanism 700. Since the strip has a high temperature and is relatively soft, it is convenient for the cutting operation; these strips 800 enter the lifting adjustable conveying mechanism side by side, and the lifting adjustable conveying mechanism adjusts the strips 800 in a horizontal state into a wavy form. In this way, a longer strip 800 can be accommodated within a cooling line of a predetermined length. These strips 800 are cooled by the cooling water sprayed by the cooling spray mechanism 700, so that the strips 800 can be fully cooled down. When the strips 800 are led out of the cooling spray mechanism 700, their temperature is reduced to the expected value; then, the side-by-side strips 800 enter the different-thickness synchronous cold rolling mechanism 1000 synchronously, and the different-thickness synchronous cold rolling mechanism 1000 performs synchronous cold rolling on these strips 800, and the thicknesses of these strips 800 after cold rolling are different. Since the thicknesses of these strips 800 after cold rolling are different, in order to avoid the situation that some strips 800 become slack, the tensioning mechanism 1200 is used to tension the slack strips 800, and in order to avoid the situation that adjacent strips 800 shift or cross, the limiting mechanism 1100 separates the adjacent strips 800 from each other. The strips 800 after cold rolling are wound into a roll by a winding roller; in summary, it can be seen that the present invention effectively shortens the length of the strip cooling line, saves space, improves the cooling efficiency, and can synchronously perform the production operation of strips with different thicknesses, thereby improving the production efficiency.

[0041] As a preferred embodiment of the present invention, as Figures 1 - 2As shown, the undulating adjustable conveying mechanism includes a first transmission roller group 200 and a second transmission roller group 300, wherein the first transmission roller group 200 and the second transmission roller group 300 are arranged opposite to each other in the vertical direction, and the two are movably connected to the machine body 100, and at the same time, the first transmission roller group 200 and the second transmission roller group 300 are movably connected to the connecting seat 501 respectively. The connecting seat 501 of this embodiment is connected to the machine body 100 through a transmission assembly 500, and the first transmission roller group 200 is transmission-connected to the transmission assembly 500, the transmission assembly 500 is transmission-connected to a driving assembly 600 installed on the machine body 100, and the second transmission roller group 300 is connected to a longitudinal push-pull mechanism 400. The working principle and advantage of this embodiment are that the side-by-side strips 800 enter between the first transmission roller group 200 and the second transmission roller, as shown in FIG. Figure 11 As shown, at this time, the first transmission roller group 200 and the second transmission roller play the role of horizontally conveying the strip 800; then, the longitudinal push-pull mechanism 400 is controlled to make the longitudinal push-pull mechanism 400 change the longitudinal position, so that Figure 12 As shown, the first transmission roller set 200 and the second transmission roller set 300 are interlaced with each other; the driving assembly 600 controls the transmission assembly 500 to move, so that the transmission assembly 500 drives the first transmission roller set 200 and the second transmission roller set 300 to open respectively, and at the same time, the first transmission roller set 200 located below moves upward, as shown in FIG. Figure 13 As shown, the strip 800 between the first drive roller set 200 and the second drive roller set 300 is in an undulating shape. In this way, a longer strip 800 can be accommodated in a cooling line of a predetermined length, and the difficulty of arranging the cooling spray mechanism 700 is reduced. At the same time, the effective area of ​​the cooling spray mechanism 700 on the strip 800 is increased, so that the undulating strip 800 is fully cooled, thereby improving the cooling effect.

[0042] As a preferred embodiment of the present invention, Figures 3 - 9As shown, the connecting seat 501 includes a first seat body 5011 and a second seat body 5014 that are connected to each other. In this embodiment, the first drive roller group 200 includes a plurality of first drive rollers, which are arranged at intervals along the conveying direction of the strip. First strip holes 5013 are respectively formed at both axial ends of each first drive roller on the first seat body 5011, and each first strip hole 5013 extends along the conveying direction of the strip. In this embodiment, the second drive roller group 300 includes a plurality of second drive rollers, which are arranged at intervals along the conveying direction of the strip. Second strip holes 5017 are respectively formed at both axial ends of each second drive roller on the second seat body 5014, and each second strip hole 5017 extends along the conveying direction of the strip. In this embodiment, a plurality of first guiding holes 101 are formed in the machine body 100, and these first guiding holes 101 gradually extend outward upward in the vertical direction. Both axial ends of each first drive roller respectively extend out of the corresponding first strip hole 5013, and the end of the first drive roller is slidably connected in the corresponding first guiding hole 101. In this embodiment, a plurality of guiding ears 5015 are formed on the second seat body 5014, and second guiding holes 5016 are formed in each guiding ear 5015; these second guiding holes 5016 gradually extend outward downward in the vertical direction, and the upper end of each second guiding hole 5016 communicates with the corresponding second strip hole 5017, and both axial ends of each second drive roller respectively extend out of the corresponding second strip hole 5017. The working principle and advantages of this embodiment are as follows: First, the longitudinal pushing and pulling mechanism 400 drives the second drive roller group 300 to displace a certain distance. After that, in this embodiment, the connecting seat 501 is driven to move upward through the transmission component 500. The first drive rollers move upward under the action of the first strip holes 5013 and the first guiding holes 101, so that the distance between the first drive rollers gradually increases. During the upward movement of the connecting seat 501, the second drive rollers of the second drive roller group 300 are under the action of the second guiding holes 5016 of the guiding ears 5015, and the distance between the second drive rollers also increases accordingly. At the same time, the first drive roller group 200 drives the strip 800 to bulge upward. Under the limitation of the first drive roller group 200 and the second drive roller group 300, the strip 800 is in a undulating shape, so that the length of the strip 800 accommodated by the undulation adjustable conveying mechanism increases. Moreover, in this embodiment, the height of the vertical displacement of the first drive roller group 200 can be adjusted according to requirements, so as to change the height of the bulge of the strip 800, so that the length of the strip 800 in the undulation adjustable conveying mechanism is the shortest on the premise of ensuring that the strip 800 is fully cooled. Moreover, according to the cooling effect, the undulation degree of the strip 800 can be adjusted in a timely manner.

[0043] As a preferred embodiment of the present invention, as Figure 1 、 3As shown in FIG. -5, the transmission assembly 500 includes first transmission wheels 503 mounted at both axial ends of each first transmission roller. A vertical sliding hole 102 is formed in the upper part of the machine body 100. A transmission rod 505 is rotatably connected to the machine body 100, and the transmission rod 505 is respectively in transmission connection with a connecting seat 501 and a movable seat 502. A second transmission wheel 504 is rotatably connected to the movable seat 502. The second transmission wheel 504 is slidably connected to the machine body 100 through the vertical sliding hole 102. A first transmission chain 506 is in transmission connection with each first transmission wheel 503 and the second transmission wheel 504 on the same side, and a drive assembly 600 is in transmission connection with the transmission rod 505. The first transmission roller set 200 of this embodiment can be actively driven to act, that is, a power motor is installed at one end of any one of the first transmission rollers, and the power motor drives the corresponding first transmission roller to rotate. Under the transmission of the first transmission chain 506, the other first transmission rollers also rotate correspondingly; the second transmission roller set 300 is in a passive action state, that is, the second transmission rollers rotate passively during the movement of the strip 800. Among them, the drive assembly 600 of this embodiment includes a drive motor 601. The output shaft of the drive motor 601 is connected to the upper end of the corresponding transmission rod 505. A third transmission wheel 602 is installed on the other transmission rod 505, and a third transmission wheel 602 is also installed on the output shaft of the drive motor 601. These two third transmission wheels 602 are in transmission connection through a second transmission chain 603 in an 8-shaped configuration. In this way, the drive motor 601 drives the transmission rod 505 to rotate, causing the connecting seat 501 and the movable seat 502 to gradually approach each other. During the upward movement of the connecting seat 501, the first transmission roller drives the part of the strip 800 in contact with it to move upward, and at the same time, the distance between the first transmission rollers gradually increases; under the action of the upward movement of the connecting seat 501, the second transmission rollers have their distance increased by the second guiding holes 5016 on the connecting seat 501.

[0044] As a preferred embodiment of the present invention, as Figure 5 、 10As shown, the transmission rod 505 includes an upper threaded rod 5051 and a lower threaded rod 5053 that are oppositely arranged in the vertical direction, and the thread directions of the upper threaded rod 5051 and the lower threaded rod 5053 are opposite. In this embodiment, one end of the upper threaded rod 5051 away from the lower threaded rod 5053 is threadedly connected to the movable seat 502, and one end of the lower threaded rod 5053 away from the upper threaded rod 5051 is threadedly connected to the connecting ear 5012 on the connecting seat 501. One end of the upper threaded rod 5051 and the lower threaded rod 5053 close to each other are respectively constructed with a first connecting flange 5052 and a second connecting flange 5054. The first connecting flange 5052 and the second connecting flange 5054 are connected by a plurality of limiting rods 5056, and one end of the first connecting flange 5052 and the second connecting flange 5054 close to each other is connected by a buffer spring 5055. The working principle and advantages of this embodiment are as follows: During the process of the transmission rod 505 being driven to rotate, the upper threaded rod 5051 and the lower threaded rod 5053 rotate in the same direction under the action of the limiting rod 5056, thereby causing the movable seat 502 and the connecting seat 501 to approach or move away from each other. Moreover, this embodiment uses a buffer spring 5055, and its main purpose is to avoid the first transmission chain 506 from bearing a large tensile force during the adjustment process, and the buffer spring 5055 can also buffer the tensile force of the strip 800 on the first transmission roller. That is, since the limiting rod 5056 passes through the first connecting flange 5052 and the second connecting flange 5054, the limiting rod 5056 can be movably connected to the first connecting flange 5052 and the second connecting flange 5054. An adjusting nut 5057 is threadedly connected to one end of the limiting rod 5056. By tightening or loosening the adjusting nut 5057, the compression amount of the buffer spring 5055 between the first connecting flange 5052 and the second connecting flange 5054 is adjusted, so that the elastic compression amount of the buffer spring 5055 changes after being subjected to an external force, thereby adjusting the range of the external force offset by the first transmission chain 506 or the first transmission roller.

[0045] As a preferred embodiment of the present invention, as Figures 7 - 9As shown in the figure, the longitudinal push-pull mechanism 400 includes a longitudinal driving oil cylinder 401, an adapter seat 402 and two guide rods 403. Among them, the adapter seat 402 is fixedly installed on the oil cylinder rod of the longitudinal driving oil cylinder 401. The two guide rods 403 are arranged side by side and fixed on the adapter seat 402. One end of the guide rod 403 away from the adapter seat 402 is inserted into the machine body 100, and the longitudinal driving oil cylinder 401 is installed on the machine body 100. Axial ends of each of the above-mentioned second transmission rollers are respectively rotatably connected with a connecting arm 301. A shaft rod 302 is connected to each connecting arm 301. The shaft rod 302 extends into the corresponding second strip-shaped hole 5017 or the second guide hole 5016. In this embodiment, the lower end of each connecting arm 301 is slidably connected with the corresponding guide rod 403. A plurality of telescopic springs 404 are sleeved on each guide rod 403, and the connecting arms 301 and the telescopic springs 404 are alternately arranged in sequence. The telescopic spring 404 is fixedly connected with the adjacent connecting arm 301. In the process of the connecting seat 501 moving upward in this embodiment, the shaft rod 302 enters the corresponding second guide hole 5016 from the second strip-shaped hole 5017. As the connecting seat 501 rises, the distance between the connecting arms 301 gradually becomes larger, and the telescopic spring 404 is gradually stretched.

[0046] As a preferred embodiment of the present invention, as Figures 15 - 18 shown, the different-thickness synchronous cold rolling mechanism 1000 includes a plurality of different-diameter cold rolling pairs of rollers, and these different-diameter cold rolling pairs of rollers are installed on the rack 900 at intervals along the strip conveying direction. Among them, the different-diameter cold rolling pair of rollers includes two different-diameter cold rolling rollers arranged oppositely in the vertical direction. Each different-diameter cold rolling pair of rollers includes a first roller body 1001, a second roller body 1002 and a third roller body 1003 which are coaxially arranged and connected to each other. The radial lengths of the first roller body 1001, the second roller body 1002 and the third roller body 1003 increase in sequence. In this way, the distance between the two relatively arranged first roller bodies 1001 is greater than the distance between the two relatively arranged second roller bodies 1002, and the distance between the two relatively arranged second roller bodies 1002 is greater than the distance between the two relatively arranged third roller bodies 1003. After the three strip strips 800 respectively pass through the distance between the first roller body 1001, the distance between the second roller body 1002 and the distance between the third roller body 1003, they are respectively cold-rolled to different thicknesses. Moreover, by replacing the first roller body 1001, the second roller body 1002 or the third roller body 1003 with different radial lengths, the different-thickness synchronous cold rolling mechanism 1000 can cold-roll strip strips 800 with different thicknesses; it is also possible to realize cold rolling of the strip strip 800 with the same thickness. In this case, the radial lengths of the first roller body 1001, the second roller body 1002 and the third roller body 1003 are the same.

[0047] As a preferred embodiment of the present invention, as Figures 15 - 16As shown in FIGS. 19, the limiting mechanism 1100 includes a cross beam 1101 horizontally installed on the frame 900, and a plurality of elastic limiting components are installed at intervals along the length direction of the cross beam 1101. Among them, each elastic limiting component includes two limiting blocks 1102 arranged at intervals along the length direction of the cross beam 1101. Guide inclined surfaces 1103 are respectively constructed at both ends of each limiting block 1102. The side surface of the strip 800 passes through the corresponding side surfaces of the limiting blocks 1102 after being guided by the guide inclined surfaces 1103. In this embodiment, a connecting plate 1104 is constructed at the upper end of each limiting block 1102, and a sliding seat 1105 is constructed at the upper end of the connecting plate 1104. The sliding seat 1105 is slidably connected to the cross beam 1101. Moreover, the two connecting plates 1104 of the limiting mechanism 1100 in this embodiment are connected by a connecting screw 1107, that is, the connecting screw 1107 passes through the two connecting plates 1104 and is movably connected to the two connecting plates 1104. A connecting spring 1108 is sleeved on the connecting screw 1107. The two ends of the connecting spring 1108 abut against the corresponding ends of the two connecting plates 1104. Moreover, locking bolts 1106 are respectively arranged on the sides of the two sliding seats 1105 away from each other. Each locking bolt 1106 is connected to the cross beam 1101, that is, the two sliding seats 1105 are located between the two locking bolts 1106. When the strip 800 passes through the limiting mechanism 1100, the side surface of the strip 800 contacts the side surface of the connecting plate 1104 and is limited by the connecting plate 1104, avoiding the problems of deflection or interlacing of the strip 800 during cold rolling. Moreover, when the strip 800 has a tendency of deflection, the side surface of the strip 800 presses the connecting plate 1104, and the connecting plate 1104 moves towards the other connecting plate 1104. At this time, the connecting spring 1108 is compressed and stores energy, thereby offsetting the external force of deflection brought by the strip 800.

[0048] As a preferred embodiment of the present invention, as Figure 20As shown in the figure, the tensioning mechanism 1200 includes a bent rod 1201. A first tensioning tube 1207 and a second tensioning tube 1208 are sleeved on the bent rod 1201. The axes of the first tensioning tube 1207 and the second tensioning tube 1208 are parallel and are respectively located at the corresponding strip 800. Wherein, a connecting shaft 1202 is constructed at one axial end of the bent rod 1201. The connecting shaft 1202 is rotatably connected to a slider 1203. The slider 1203 is slidably connected to the frame 900. And a locking nut 1204 is threadedly connected to the connecting shaft 1202. The locking nut 1204 is locked on the slider 1203. Moreover, an adjusting bolt 1205 is rotatably connected to the upper end of the slider 1203. The adjusting bolt 1205 is threadedly connected to the frame 900. A lower end of the slider 1203 is connected to an energy storage spring 1206. The energy storage spring 1206 is connected to the frame 900. The working principle and advantages of this embodiment are as follows: In this embodiment, since the axes of the first tensioning tube 1207 and the second tensioning tube 1208 are parallel, that is, their axes do not coincide, the first tensioning tube 1207 and the second tensioning tube 1208 are respectively tensioned on the surfaces of the corresponding strips 800. And after cold rolling, the thinner strip 800 will become loose. At this time, the locking nut 1204 needs to be loosened so that the connecting shaft 1202 and the slider 1203 can rotate relative to each other. Then, the connecting shaft 1202 is rotated by a certain angle. At the same time, the adjusting bolt 1205 is rotated according to the needs, so that the slider 1203 moves a certain displacement in the vertical direction, so that the first tensioning tube 1207 and the second tensioning tube 1208 respectively tension the corresponding strips 800, so that each strip 800 is in a tensioned state. Finally, the locking nut 1204 is tightened and the adjusting bolt 1205 is fixed.

[0049] As a preferred embodiment of the present invention, as Figure 14 shown, the cooling spray mechanism 700 includes a connecting pipe 701 and an adjusting pipe 702. The connecting pipe 701 is connected to the cooling water inlet. The lower end of the connecting pipe 701 is inserted into the upper end of the adjusting pipe 702. The lower end of the adjusting pipe 702 is connected to a plurality of liquid guide pipes 704 through a longitudinal distribution pipe 703. And these liquid guide pipes 704 are arranged at intervals along the length direction of the longitudinal distribution pipe 703. In this embodiment, a plurality of transverse spray pipes 705 are connected to each liquid guide pipe 704 at intervals in the vertical direction. The piston rod of the vertical driving oil cylinder 706 is connected to the adjusting pipe 702. In this embodiment, the vertical driving oil cylinder 706 drives the adjusting pipe 702 to move in the vertical direction. Furthermore, the adjusting pipe 702 drives all the liquid guide pipes 704 to move in the vertical direction through the longitudinal distribution pipe 703, so that the cooling water sprayed by the transverse spray pipes 705 covers the undulating area of the strip 800, realizing that the cooling spray mechanism 700 changes accordingly with the undulating degree of the strip 800, achieving the purpose of fully cooling the strip 800.
