Description

Technical Field

[0001] The present invention belongs to the technical field of steel coil turning and transportation, and particularly relates to an adaptive steel coil turning machine, a turning system and a method. Background Art

[0002] The steel coil transportation system is a key equipment in metallurgical steel plants and is a bridge connecting upstream and downstream units, undertaking multiple processes such as receiving coils, transporting coils, and turning coils. Whether the steel coil transportation system can accurately and reliably transport the steel coil to the next process according to the process requirements has become a key link directly affecting production. There are various forms of steel coil transportation systems, including vertical coil transportation systems, horizontal coil transportation systems, and steel coil turning and transportation systems. In order to meet the process requirements of upstream and downstream units, it is often necessary to switch between vertical coils and horizontal coils. For example, the steel coils coming out of the bell-type annealing furnace are generally vertical coils. Before the steel coils come out of the bell-type annealing furnace and enter the downstream temper mill or recoiling mill, the turning machine in the steel coil turning and transportation system needs to turn the vertical coil into a horizontal coil. The process is as follows: The vertical coil coming out of the bell-type annealing furnace is transported by the overhead crane to the entrance saddle of the steel coil turning and transportation system. The vertical coil on the entrance saddle is transported by the entrance steel coil transportation device to the turning saddle. The vertical coil is turned into a horizontal coil by the turning machine, and the horizontal coil is transported by the exit steel coil transportation device to the downstream unit.

[0003] Since there is a deviation in the lateral position when the overhead crane hoists the vertical coil to the entrance saddle of the steel coil turning and transportation system, that is, in the direction perpendicular to the entrance steel coil transportation direction, there is a deviation between the center line of the vertical coil and the center line of the entrance steel coil transportation device. And during the process of the entrance steel coil transportation device transporting the vertical coil on the entrance saddle to the turning saddle, the lateral position deviation of the vertical coil cannot be corrected. Therefore, the existing turning machine has a great impact on the turning machine when turning the vertical coil into a horizontal coil, which seriously affects the service life of the turning machine and there are great potential safety hazards.

[0004] Regarding the impact and potential safety hazards during turning caused by the lateral position deviation of the vertical coil, if a structure can be designed specifically to enable the V-shaped saddle to automatically adjust according to the lateral position of the vertical coil, the impact and potential safety hazards during turning caused by the lateral position deviation of the vertical coil can be eliminated, thereby improving the service life of the turning machine.

[0015] An adaptive steel coil rolling and unrolling method, using the adaptive steel coil rolling and unrolling system, the steps are as follows: Step 1: Adjust the flat saddle to a horizontal position. After the adaptive steel coil rolling and unrolling machine receives the rolling and unrolling instruction, the PLC control system controls the rod of the rolling and unrolling hydraulic cylinder to extend, driving the rolling and unrolling seat to rotate clockwise by 90°, so that the flat saddle is in the horizontal direction. Step 2: Adjust the flat saddle to the right extreme position. The PLC control system controls the rod of the flat saddle moving hydraulic cylinder to extend, driving the flat saddle to horizontally move on the rolling and unrolling seat to the right extreme.

[0016] Beneficial effects: (1) The coil-turning machine in the present invention can stably and safely turn the vertical coil with a deviation in the horizontal position into a horizontal coil, and automatically complete the horizontal centering of the coil during the coil-turning process.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: According to Figures 1-10 An adaptive steel coil turning machine shown in the figure includes A fixed base 201; A turning seat 202, which is rotatably connected to the top of the fixed base 201; A driving mechanism, which is rotatably connected to the fixed base 201, and its output end is rotatably connected to the turning seat 202; A coil receiving mechanism, which is connected to the upper surface of the turning seat 202 and is used for storing the vertically placed steel coil 500 after adjusting the position; A turning swing bearing mechanism, which is connected to the turning seat 202 and is used for contacting the vertically placed steel coil 500 after adjusting the position and bearing the steel coil 500 after flipping.

[0035] In some embodiments, the fixed base 201 includes a bottom plate 2011, a first connecting seat 2012 and a second connecting seat 2013; the first connecting seat 2012 and the second connecting seat 2013 are respectively fixedly connected to both sides of the bottom plate 2011; the top end of the first connecting seat 2012 is rotatably connected to the tail end of the turning hydraulic cylinder 203; the top end of the second connecting seat 2013 is rotatably connected to the flat saddle mounting arm 2021 in the turning seat 202.

[0036] In some embodiments, the turning seat 202 at least includes a flat saddle mounting arm 2021, a V-shaped saddle mounting arm 2022 and a connecting rod 2023, and the flat saddle mounting arm 2021, the V-shaped saddle mounting arm 2022 and the connecting rod 2023 are an integral structure; the flat saddle mounting arm 2021 and the V-shaped saddle mounting arm 2022 are arranged at 90°; a connecting rod 2023 is arranged on one side surface of the flat saddle mounting arm 2021; the free end of the connecting rod 2023 is inclined obliquely downward and is rotatably connected to the driving mechanism; the bottom surface of the flat saddle mounting arm 2021 is rotatably connected to the fixed base 201; the flat saddle mounting arm 2021 is used for connecting the coil receiving mechanism; the V-shaped saddle mounting arm 2022 is used for connecting the turning swing bearing mechanism.

[0037] In specific applications, the turning seat 202 is a welded integral structure. The position where the connecting rod 2023 is arranged depends on the layout of the equipment before and after the unit, and it is appropriate that there is no interference, that is, the connecting rod 2023 is inclined downward below the horizontal line.

[0038] In some embodiments, the driving mechanism employed is a rolling-up hydraulic cylinder 203; the output end of the rolling-up hydraulic cylinder 203 is rotatably connected to the rolling-up seat 202, and the tail end of the rolling-up hydraulic cylinder 203 is rotatably connected to the fixed base 201.

[0039] The adoption of this technical solution makes it easy to push and pull the connecting rod 2023. When it is necessary to receive and roll the coil for flipping, under the control of the PLC control system, the cylinder rod of the rolling-up hydraulic cylinder 203 extends, driving the rolling-up seat 202 to rotate clockwise by 90°, so that the flat saddle 204 is in the horizontal direction; then, the PLC control system controls the coil receiving mechanism and the rolling and swinging bearing mechanism to make adjustments. After the steel coil 500 is in full contact with the rolling and swinging bearing mechanism, the PLC control system controls the cylinder rod of the rolling-up hydraulic cylinder 203 to retract, driving the rolling-up seat 202 to rotate counterclockwise by 90°, so that the V-shaped saddle 207 is in the horizontal direction, completing the flipping action of the steel coil 500. Since the above process makes the steel coil 500 in full contact with the rolling and swinging bearing mechanism, the impact of the steel coil 500 on the adaptive steel coil rolling machine 200 is avoided during flipping, thereby improving the service life of the rolling machine and eliminating the potential safety hazards during rolling.

[0040] In some embodiments, the coil receiving mechanism includes a flat saddle 204 and a flat saddle moving hydraulic cylinder 205; the flat saddle 204 is slidably connected to the rolling-up seat 202; the tail end of the flat saddle moving hydraulic cylinder 205 is fixedly connected to the rolling-up seat 202, and the output end of the flat saddle moving hydraulic cylinder 205 is connected to the flat saddle 204.

[0041] When it is necessary to receive the coil, the cylinder rod of the flat saddle moving hydraulic cylinder 205 extends, pushing the flat saddle 204 to move horizontally to the right limit on the rolling-up seat 202; the PLC control system controls the inlet steel coil transportation device 100 to transport the vertically placed steel coil 500 at the outlet saddle to the flat saddle 204 of the rolling machine; after the rolling and swinging bearing mechanism makes position adjustments according to the width of the steel coil 500 to be flipped, the PLC control system controls the cylinder rod of the flat saddle moving hydraulic cylinder 205 to retract, driving the flat saddle 204 to move horizontally to the left on the rolling-up seat 202, making the vertically placed steel coil 500 close to the V-shaped saddle 207 in the rolling and swinging bearing mechanism until any one of the two V-shaped saddle coil approaching detection elements 210 detects the steel coil 500 and then stops.

[0042] In specific applications, the flat saddle 204 is slidably connected to the flat saddle mounting arm 2021 of the rolling-up seat, and the flat saddle 204 is used to store the vertical coil. The flat saddle moving hydraulic cylinder 205 can drive the flat saddle 204 to move left and right on the rolling-up seat 202; when the flat saddle 204 moves left on the rolling-up seat 202, the vertically placed steel coil 500 approaches the V-shaped saddle 207, and when the flat saddle 204 moves right on the rolling-up seat 202, the vertically placed steel coil 500 moves away from the V-shaped saddle 207.

[0043] In some embodiments, the rolling and swinging bearing mechanism includes two sets of bearing units with the same structure; the two sets of bearing units are slidably connected to the rolling base 202 relatively.

[0044] Furthermore, each set of the bearing units includes a transition seat 206, a V-shaped saddle 207, a V-shaped saddle moving hydraulic cylinder 208, a V-shaped saddle swinging hydraulic cylinder 209 and a coil approaching detection element 210; the transition seat 206 is slidably connected to the rolling base 202; the V-shaped saddle 207 is rotatably connected to the transition seat 206; the tail of the V-shaped saddle moving hydraulic cylinder 208 is connected to the rolling base 202, and the telescopic end of the V-shaped saddle moving hydraulic cylinder 208 is connected to the transition seat 206; the tail of the V-shaped saddle swinging hydraulic cylinder 209 is rotatably connected to the transition seat 206, and the telescopic end of the V-shaped saddle swinging hydraulic cylinder 209 is rotatably connected to the outer side surface of the V-shaped saddle 207; the junction of the inner side surface and the top surface of the V-shaped saddle 207 is an inclined surface, and the coil approaching detection element 210 is connected to the inclined surface.

[0045] During actual use, the transition seat 206 is slidably connected to the V-shaped saddle mounting arm 2022 of the rolling base 202; the V-shaped saddle moving hydraulic cylinder 208 drives the transition seat 206 to drive the V-shaped saddle 207 to move up and down on the rolling base 202, so as to adapt to the width requirement of the steel coil 500, as Figure 1 、 Figure 2 shown.

[0046] The V-shaped saddle swinging hydraulic cylinder 209 can drive the corresponding side V-shaped saddle 207 to swing on the transition seat 206, so that the V-shaped saddle 207 approaches or moves away from the steel coil 500, as Figure 4 shown.

[0047] The V-shaped saddle coil approaching detection element 210 is used to detect whether the steel coil 500 contacts the V-shaped saddle 207; the V-shaped saddle coil approaching detection element 210 is electrically connected to the PLC control system.

[0048] Embodiment Two: According to Figures 1-7An adaptive steel coil rolling and unrolling system shown in the figure includes at least an adaptive steel coil rolling and unrolling machine 200, and also includes a PLC control system, an inlet steel coil transportation device 100 and an outlet steel coil transportation device 300; the inlet steel coil transportation device 100 and the outlet steel coil transportation device 300 are symmetrically arranged on both sides of the center line of the adaptive steel coil rolling and unrolling machine 200; the inlet steel coil transportation device 100 is arranged at the inlet of the adaptive steel coil rolling and unrolling machine 200, and the outlet steel coil transportation device 300 is arranged at the outlet of the adaptive steel coil rolling and unrolling machine 200; the PLC control system is electrically connected to the adaptive steel coil rolling and unrolling machine 200, the inlet steel coil transportation device 100 and the outlet steel coil transportation device 300 respectively; the PLC control system is used to control the coil receiving of the adaptive steel coil rolling and unrolling machine 200, the telescopic start and stop of the driving mechanism, the adjustment of the rolling and swinging bearing mechanism, and control the vertical coil output of the inlet steel coil transportation device 100 and the horizontal coil input of the outlet steel coil transportation device 300.

[0049] During actual operation, along the steel coil conveying direction, the vertically placed steel coil 500 lifted by the overhead crane is conveyed by the inlet steel coil transportation device 100 to the flat saddle 204 of the adaptive steel coil rolling and unrolling machine; at this time, in the direction perpendicular to the transportation direction of the inlet steel coil 500, there is a lateral deviation between the center line of the steel coil 500 and the center line of the inlet steel coil transportation device 100. The adaptive steel coil rolling and unrolling machine 200 adjusts and flips the steel coil 500 into a horizontally placed steel coil 500, and the horizontally placed steel coil 500 is placed on the V-shaped saddle 207 of the adaptive steel coil rolling and unrolling machine 200. The above process automatically completes lateral centering, and the horizontally placed steel coil 500 is conveyed by the outlet steel coil transportation device 300 to the downstream unit.

[0050] When the vertically placed steel coil 500 is flipped into a horizontally placed steel coil 500 by the adaptive steel coil rolling and unrolling machine 200, the horizontally placed steel coil 500 is placed on the V-shaped saddle 207 of the adaptive steel coil rolling and unrolling machine, and under the action of gravity, the horizontally placed steel coil 500 automatically rolls to the middle of the two V-shaped saddles 207 as the V-shaped saddle 207 swings, automatically completing lateral centering.

[0051] The PLC control system in this embodiment adopts the existing technology, which at least includes a signal receiving module, a calculation module and a signal sending module, so as to complete the signal receiving of the inlet steel coil transportation device 100, the outlet steel coil transportation device 300 and the adaptive steel coil rolling and unrolling machine 200 and the sending of control instructions, and smoothly realize the rolling and conveying operations of the steel coil.

At this time, the V-shaped saddle 207 where the coil approaching detection element 210 that detects the steel coil 500 is in contact with the steel coil 500, and the V-shaped saddle 207 where the coil approaching detection element 210 that does not detect the steel coil 500 is not in contact with the steel coil 500; Step 6: Adjust the V-shaped saddle 207 until both coil approaching detection elements 210 detect the steel coil 500; The PLC control system controls the rod of the V-shaped saddle swing hydraulic cylinder 209 where the coil approaching detection element 210 that did not detect the steel coil 500 in Step 5 to extend, driving the V-shaped saddle 207 that is not in contact with the steel coil 500 to swing on the transition seat 206 in the direction approaching the steel coil 500 until the coil approaching detection element 210 on this V-shaped saddle 207 detects the steel coil 500 and stops; Step 7: Adjust the V-shaped saddle 207 to be horizontal; The PLC control system controls the rod of the turning hydraulic cylinder 203 to retract, driving the turning seat 202 to rotate counterclockwise by 90°, so that the V-shaped saddle 207 is in the horizontal direction; Step 8: Horizontally center the steel coil 500; In the sixth control step of the PLC control system, the rod of the V-shaped saddle swing hydraulic cylinder 209 for the action retracts, driving the V-shaped saddle 207 to swing slowly away from the steel coil 500 on the transition seat 206 until the rod of the V-shaped saddle swing hydraulic cylinder 209 is fully retracted and then stops, completing the coil turning action; during this process, the steel coil 500 rolls under the action of gravity to the middle of the two V-shaped saddles 207, automatically completing the lateral centering.

10. An adaptive steel coil rolling method, characterized in that: Adopt the adaptive steel coil turning system described in claim 9, and the steps are as follows: Step 1: Adjust the flat saddle to a horizontal position. After the adaptive steel coil turning machine (200) receives a turning instruction, the PLC control system controls the rod of the turning hydraulic cylinder (203) to extend, driving the coil-turning seat (202) to rotate clockwise by 90°, so that the flat saddle (204) is in a horizontal direction. Step 2: Adjust the flat saddle to the right extreme position. The PLC control system controls the rod of the flat saddle moving hydraulic cylinder (205) to extend, driving the flat saddle (204) to horizontally move to the right extreme on the coil-turning seat (202). Step 3: The flat saddle (204) receives the vertically placed steel coil (500). The PLC control system controls the inlet steel coil transportation device (100) to transport the vertically placed steel coil (500) on the outlet saddle to the flat saddle (204) of the turning machine. Step 4: Adjust the vertical position of the V-shaped saddle (207). According to the width of the steel coil (500), the PLC control system controls the movement of the V-shaped saddle moving hydraulic cylinder (208), driving the V-shaped saddle (207) to move up and down on the coil turning base (202) to a suitable position where it can contact the vertically placed steel coil (500). Step Five: Adjust the V-shaped saddle (207) until it is in full contact with the vertically placed steel coil (500). The PLC control system controls the rod of the flat saddle moving hydraulic cylinder (205) to retract, driving the flat saddle (204) to move horizontally to the left on the coil turning base (202), bringing the vertically placed steel coil (500) closer to the V-shaped saddle (207) until either one of the two coil approaching detection elements (210) on the V-shaped saddle detects the steel coil (500) and then stops. At this time, the V-shaped saddle (207) where the coil approaching detection element (210) that detects the steel coil (500) is located is in contact with the steel coil (500), and the V-shaped saddle (207) where the coil approaching detection element (210) that does not detect the steel coil (500) is located is not in contact with the steel coil (500). Step Six: Adjust the V-shaped saddle (207) until both coil approaching detection elements (210) detect the steel coil (500). The PLC control system controls the rod of the V-shaped saddle swing hydraulic cylinder (209) where the coil approaching detection element (210) that did not detect the steel coil (500) in Step Five to extend, driving the V-shaped saddle (207) that is not in contact with the steel coil (500) to swing towards the steel coil (500) on the transition base (206) until the coil approaching detection element (210) on this V-shaped saddle (207) detects the steel coil (500) and then stops. Step Seven: Adjust the V-shaped saddle (207) to be horizontal. The PLC control system controls the rod of the coil turning hydraulic cylinder (203) to retract, driving the coil turning base (202) to rotate counterclockwise by 90°, making the V-shaped saddle (207) in the horizontal direction. Step Eight: Horizontally center the steel coil (500). The PLC control system controls the rod of the V-shaped saddle swing hydraulic cylinder (209) that moved in Step Six to retract, driving this V-shaped saddle (207) to slowly swing away from the steel coil (500) on the transition base (206) until the rod of this V-shaped saddle swing hydraulic cylinder (209) is fully retracted and then stops, completing the coil turning action. During this process, the steel coil (500) rolls to the middle of the two V-shaped saddles (207) under the action of gravity, automatically completing the horizontal centering.
