Description

Technical Field

[0001] The invention relates to the technical field of cold-rolled strip steel production, and in particular to a strip steel coiling system and a coiling aid. Background Art

[0002] When coiling the strip steel, when the main working condition is thick plate coiling, the coiler reel is mostly a reel with jaws, and no coiler is needed at this time; when the main working condition is thin plate coiling, a quadrangular pyramid fan-shaped block reel is generally used, and a coiler is needed to assist in coiling 3 to 5 turns. At present, a coiling system is suitable for a small thickness variation of the strip steel. CN110170544A and CN110814084A respectively disclose a coiling device.

[0003] In strip rolling production, there are increasingly higher requirements for equipment with multiple uses and strong adaptability. This requires a coiling system that can accommodate increasingly wider variations in the thickness and strength of steel plates.

[0004] However, the jaw reel that can adapt well to thick plates is often no longer suitable for thin plates. There are two main reasons: first, due to the gap between the fan-shaped plates of the reel and the existence of the jaws, indentations will appear on the inner circle of the finished steel coil, affecting the surface quality and yield rate of the strip; second, as the thickness of the steel plate decreases, the stability and uniformity of the clamping deteriorate, and it may even fail to clamp or partially tear.

[0005] Similarly, for light coilers and matching light winders suitable for winding thin plates, due to insufficient winding capacity for thick plates and limitations of their own stiffness and strength, it is not easy for thick plates to be reliably wound and adhered to the surface of the reel, resulting in unstable winding process. Summary of the invention

[0035] The present invention provides a winding aid for winding a reel of a winding machine, comprising:

[0036] Roll-assisting moving mechanism;

[0037] A rolling-assisting belt is installed on the rolling-assisting moving mechanism, and the rolling-assisting moving mechanism can drive the rolling-assisting belt to move between a rolling-assisting position and a waiting position. When the rolling-assisting belt is located at the rolling-assisting position, the rolling-assisting belt partially wraps around the reel; when the rolling-assisting belt is located at the waiting position, the rolling-assisting belt deviates from the reel;

[0038] A first swing arm device is installed on the auxiliary rolling movement mechanism, the first swing arm device comprises a first guide head and a first driving mechanism, the first guide head has a first arc surface, and when the auxiliary rolling belt is located at the auxiliary rolling position, the first driving mechanism can drive the first guide head to swing to the first swing arm auxiliary rolling position;

[0039] a second swing arm device, which is installed on the first swing arm device, the second swing arm device comprises a second guide head and a second driving mechanism, the second guide head has a second arc surface, and when the first swing arm device is located at the first swing arm auxiliary rolling position, the second driving mechanism can drive the second guide head to swing to the second swing arm auxiliary rolling position;

[0042] The characteristics and advantages of the present invention are:

[0043] When the strip steel coiling system is working, the coiling belt moves to the coiling position, and the strip head enters between the coiling belt and the reel, completing a bite as the reel rotates. For strip steels of different thicknesses, the coiler can include two working modes to facilitate the secondary bite of the strip head.

[0044] For thinner strips, the first guide head swings to the first swing arm assisting winding position, and the second guide head is retracted. After the strip head completes the first bite, it continues to move along the reel and passes through the channel between the reel wall and the first curved surface. Under the constraint of the first curved surface, the cutting angle formed by the strip head and the subsequent strip is small, which facilitates the smooth completion of the second bite.

[0045] For thicker strip steel, the first guide head swings to the first swing arm auxiliary winding position, and the second guide head swings to the second swing arm auxiliary winding position. After the strip head completes the first bite, it continues to move along the reel, and passes through the channel between the drum wall and the first curved surface and the channel between the drum wall and the second curved surface in turn. Under the action of the first curved surface and the second curved surface, the strip steel will obtain a larger wrap angle with the reel; at the same time, since the yield strength of thicker strip steel is larger, in this mode, the first curved surface and the second curved surface jointly constrain the strip steel, which can make the cutting angle formed by the strip head and the subsequent strip steel smaller, and the second bite can be completed smoothly.

[0046] After the second bite is completed and the strip can be stably wound with the reel, the first guide head and the second guide head are retracted to facilitate the auxiliary winding belt to return to the waiting position and the auxiliary winding belt to move to the auxiliary winding position again for the next roll.

[0047] The coiling aid can select different working modes, which are respectively suitable for thinner strip steel and thicker strip steel, thereby expanding the thickness variation range of the strip steel applicable to the strip coiling system. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] Embodiment 1

[0080] The present invention provides a strip steel coiling system, such as Figure 1-Figure 4 As shown, the strip coiling system includes a coiler 1 and an auxiliary coiler 3. The coiler 1 includes a reel 11 and a coiling drive device 110 for driving the reel 11 to rotate. The auxiliary coiler 3 includes: an auxiliary coiling moving mechanism 30, an auxiliary coiling belt 36, a first swing arm device 33 and a second swing arm device 34. The auxiliary coiling belt 36 is installed on the auxiliary coiling moving mechanism 30. The auxiliary coiling moving mechanism 30 can drive the auxiliary coiling belt 36 to move between the auxiliary coiling position and the waiting position. When the auxiliary coiling belt 36 is at the auxiliary coiling position, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the auxiliary winding belt 36 partially wraps around the reel 11; when the auxiliary winding belt 36 is in the waiting position, the auxiliary winding belt 36 deviates from the reel 11; the first swing arm device 33 is installed on the auxiliary winding moving mechanism 30, the first swing arm device 33 includes a first guide head 335 and a first driving mechanism 330, the first guide head 335 has a first arc surface 3351, when the auxiliary winding belt 36 is in the auxiliary winding position, the first driving mechanism 330 can drive the first guide head 335 to swing to the first swing arm auxiliary winding position; the second swing arm device 34 is installed on the first swing arm device 33, the second swing arm device 34 includes a second guide head 341 and a second driving mechanism 340, the second guide head 341 has a second arc surface 3411, when the first swing arm device 33 is in the first swing arm auxiliary winding position, the second driving mechanism 340 can drive the second guide head 341 to swing to the second swing arm auxiliary winding position; when the first guide head 335 is in the first swing arm auxiliary winding position, as shown Fig.10 As shown, the first curved surface 3351 cooperates with the wall of the reel 11, and the strip head wound between the reel 11 and the auxiliary winding belt 36 can pass through the channel between the wall of the reel 11 and the first curved surface 3351; when the second guide head 341 is located at the second swing arm auxiliary winding position, as shown in FIG. Fig.11As shown, the second curved surface 3411 cooperates with the wall of the reel 11, and the head of the strip steel wound between the reel 11 and the auxiliary winding belt 36 can pass through the channel between the wall of the reel 11 and the first curved surface 3351 and the channel between the wall of the reel 11 and the second curved surface 3411 in sequence.

[0081] When the strip steel coiling system is working, the coiling belt 36 moves to the coiling position, and the coiling belt 36 partially wraps around the reel 11. The side of the reel 11 not wrapped by the coiling belt 36 is the inlet side, that is, Figure 1-Figure 4 The left side of the reel 11 is the inlet side, and the strip head enters between the auxiliary winding belt and the reel through the inlet side, and completes a bite with the rotation of the reel. For strip steels of different thicknesses, the auxiliary winding device can include two working modes to facilitate the secondary bite of the strip head.

[0082] For thinner strip steel, such as Figure 1 , Figure 6 and Fig.10 As shown, the first guide head 335 swings to the first swing arm assisting winding position, and the second guide head 341 is in a retracted state. After the strip head completes the first bite, it continues to move along the reel 11 and passes through the channel between the wall of the reel 11 and the first curved surface 3351. Under the constraint of the first curved surface 3351, the cutting angle formed by the strip head and the subsequent strip is small, which facilitates the smooth completion of the second bite.

[0083] For thicker strip steel, such as Figure 2 , Figure 7 and Fig.11 As shown, the first guide head 335 swings to the first swing arm auxiliary winding position, and the second guide head 341 swings to the second swing arm auxiliary winding position. After the strip head completes the first bite, it continues to move along the reel 11, and passes through the channel between the wall of the reel 11 and the first curved surface 3351 and the channel between the wall of the reel 11 and the second curved surface 3411. Under the action of the first curved surface 3351 and the second curved surface 3411, the strip steel will obtain a larger wrap angle with the reel; at the same time, since the yield strength of the thicker strip steel is larger, in this mode, the first curved surface 3351 and the second curved surface 3411 jointly constrain the strip steel, so that the cutting angle formed by the strip head and the subsequent strip steel can be smaller, and the second bite can be completed smoothly.

[0084] After the second bite is completed and the strip can be stably wound with the reel 11, the first guide head 335 and the second guide head 341 are retracted to facilitate the winding belt 36 to return to the waiting position, and the winding belt 36 moves to the winding position again when the next roll is made. The winding device 3 can select different working modes, which are respectively suitable for thinner and thicker strips, thereby expanding the thickness variation range of the strip applicable to the strip winding system.

Thus, when the first guide head 335 swings to the first swing arm auxiliary rolling position, Figure 6 and Figure 7 As shown, the swing arm support roller 332 can drive the auxiliary winding belt 36 to wrap around the reel 11 more, increasing the wrap angle between the auxiliary winding belt 36 and the reel 11; when the first guide head 335 swings to the retracted state, as shown in FIG. Figure 4 As shown, the swing arm support roller 332 is also retracted together to facilitate the retraction of the winding belt 36.

[0093] Specifically, Figure 4 and Figure 5As shown, the swing arm support roller 332 and the lower swing arm roller 334 are connected to the swing arm frame 331, and the swing arm frame 331 is connected with a hinge pin 333. The swing arm frame 331 is a steel plate welded structure, with a swing arm support roller 332 mounting shaft hole welded on the top, and a second swing arm device hinge point coaxial therewith, and a mounting seat of the second swing arm hydraulic cylinder 39 is also welded on the swing arm frame 331, and a shaft hole seat for mounting a hinge pin 333 is provided at the lower part of the swing arm frame 331. The hinge pin 333 hinges the swing arm frame 331 on the carriage 321 on the one hand, and provides support for the spindle of the lower swing arm roller 334 at the same time. The swing arm support roller 332 adopts a spindle structure, and is fixed in the mounting shaft hole at the top of the swing arm frame 331 through a pair of spherical bearings, and the roller is supported on the spindle through a roller bearing and can rotate freely around the spindle. The lower swing arm roller 334 also adopts a spindle structure and is directly fixed in the pin hole of the hinge pin 333. The roller is supported on the spindle through a roller bearing and can rotate freely around the spindle. The first guide head 335 is installed on the top of the swing arm frame 331 and is coaxial with the swing arm support roller 332. The two are independent of each other and the angle adjustment is achieved by the arc-shaped long hole set on the first guide head 335. When the cylinder rod of the first swing arm hydraulic cylinder 38 is extended, the first swing arm device 33 is in working state. By fine-tuning the angle of the first guide head 335, it is ensured that there is a suitable gap between the first guide head 335 and the reel to ensure the wrap angle and pass angle during the strip coiling process.

[0094] The second swing arm device 34 is an assembly part, including a second guide head 341 and a rocker arm 342, and the second guide head 341 is installed on the rocker arm 342. The swing point of the rocker arm 342 is set at the second swing arm device hinge point on the first swing arm device 33, and the rocker arm 342 is hinged to the cylinder rod of the second swing arm hydraulic cylinder 39. When the second swing arm hydraulic cylinder 39 is extended, the rocker arm 342 swings inward, and the second guide head overlaps the first guide head 335 on the first swing arm device 33.

[0095] In one embodiment of the present invention, the first guide head 335 has a first guide plate 3352. When the first guide head 335 is located at the first swing arm auxiliary winding position and the second guide head 341 is located below the first guide head 335, the first guide plate 3352 can guide the strip head to move toward the entrance between the auxiliary winding belt 36 and the reel 11, so that the strip with a smaller thickness can be bitten more smoothly.

[0096] In one embodiment of the present invention, Figure 8 and Fig. 9As shown, the second guide head 341 has a second guide plate 3412. When the second guide head 341 is located at the second swing arm auxiliary winding position, the second guide plate 3412 is located above the first guide head 335. The second guide plate 3412 can receive the thicker strip steel coming from above and guide the strip head to move toward the entrance between the auxiliary winding belt 36 and the reel 11, so that the thicker strip steel can be bitten more smoothly. Preferably, the length of the second guide plate 3412 is greater than the length of the first guide plate 3352.

[0097] Normally, when the thickness of the strip does not change much and the tension variation range is small, there is generally no need to use a tension roller to achieve a gradient drop in tension. The strip enters the coiling system through a single channel, and there is no need to switch the coiling channel according to the incoming material conditions and process requirements. However, with the increasing demand for equipment systems with multiple uses and strong product compatibility, the existing coiling system is no longer suitable for working conditions with large changes in incoming material direction and thickness. Figure 1 and Figure 2 As shown, the strip steel coiling system provided by the present invention includes a tension roller mechanism 50, and the tension roller mechanism 50 includes an upper pressure roller 51, an upper tension roller 52, a lower tension roller 53 and a lower pressure roller 54 arranged in sequence from top to bottom; the strip head can pass through between the upper pressure roller 51 and the upper tension roller 52 and move toward the reel 11, or pass through between the lower pressure roller 54 and the lower tension roller 53 and move toward the reel 11. In this way, the tension roller mechanism 50 realizes dual-channel output, the thicker strip steel comes out of the upper channel, and the tension roller mechanism 50 is used as a steering roller; the thinner strip steel comes out of the lower channel, and the tension roller mechanism 50 is used as an S roller, providing a step-down stable back tension for the strip steel coiling system. The dual-channel configuration can realize the coiling of bidirectional incoming materials, which is more convenient to adapt to large thickness changes, tension changes required for coiling strips, and various rolling processes.

[0098] Taking into account the situation that the strip is a high-quality steel thick plate, after the first bite, it is necessary to increase the wrap angle of the strip to the reel 11 as much as possible and reduce the angle between the strip head and the subsequent strip at the entrance in order to successfully complete the second bite and realize the continuation of the coiling process. The above-mentioned design of the first swing arm device 33 and the second swing arm device 34 cooperating with each other, and the design that enables the strip to enter the auxiliary coiler 3 through two different channels are based on this consideration.

[0099] reel

[0100] like Figure 14-16As shown, the reel 11 includes a main shaft 114, an expansion and contraction drive cylinder 116, an axially inclined wedge 112, a plurality of radially inclined wedges 113, a plurality of fan-shaped plates 111 and a shrinking spring 1132, wherein the radially inclined wedge 113 has a fan-shaped cylindrical surface 1131; the axially inclined wedge 112 is installed on the main shaft 114, and the axially inclined wedge 112 can move along the axial direction of the main shaft 114, and the expansion and contraction drive cylinder 116 is connected to the axially inclined wedge 112; the plurality of radially inclined wedges 113 and the plurality of fan-shaped plates 111 are alternately distributed around the main shaft 114, the radially inclined wedges 113 and the axially inclined wedges 112 are matched with each other by wedge surfaces, and the fan-shaped plates 111 support The expansion and contraction drive cylinder 116 can drive the axial wedge 112 to move axially along the main shaft 114, and the axial wedge 112 can drive the radial wedge 113 to move radially outward along the main shaft 114. The radial wedge 113 can push the fan plate 111 to move radially outward along the main shaft 114, and the radial wedge 113 can move to the fan-shaped cylindrical surface 1131 and connect with the outer fan-shaped surface 1111 of the fan plate 111; the shrinking spring 1132 is connected to the fan plate 111, so that the fan plate 111 has a tendency to move radially inward along the main shaft 114.

[0101] The expansion and contraction driving cylinder 116 drives the axial wedge 112 to move axially relative to the main shaft 114, and the radial wedge 113 cooperates with the axial wedge 112 with a wedge surface, so that the axial wedge 112 drives the radial wedge 113 to move radially relative to the main shaft 114, and at the same time, the radial wedge 113 drives the fan plate 111 to move radially; multiple radial wedges 113 and multiple fan plates 111 are alternately distributed around the main shaft, and the radial wedge 113 moves radially outward, so that the fan-shaped cylindrical surface 1131 of the radial wedge 113 can be connected with the outer fan-shaped surface 1111 of the fan plate 111; the radial wedge 113 moves radially inward, so that the outer fan-shaped surfaces 1111 on two adjacent fan plates 111 can be connected.

[0102] In one embodiment, the axial wedge 112 may be a cylindrical rotating body structure, and a plurality of wedge surface structures are distributed circumferentially on the axial wedge 112, and each wedge surface structure corresponds to each radial wedge 113. Fig.15 and Fig.16 As shown, the reel 11 includes a plurality of axially inclined wedges 112 distributed circumferentially around the main shaft 114, and each axially inclined wedge 112 corresponds to each radially inclined wedge 113. A support shaft head 117 is provided at the end of the main shaft 114, and the radially inclined wedges 113 abut against the support shaft head 117. The expansion and contraction drive cylinder 116 drives the axially inclined wedge 112 to move axially relative to the main shaft 114. The connection method between the expansion and contraction drive cylinder 116 and the axially inclined wedge 112 is not limited to one. In one embodiment, the piston of the expansion and contraction drive cylinder 116 is connected to the axially inclined wedge 112 through the core shaft 115 and the cross block 119.

[0103] When the reel 11 expands, the expansion and contraction drive cylinder 116 has oil in the rod cavity, the piston moves backward, and the mandrel 115 moves toward the transmission side. The mandrel 115 pulls the axial wedge 112 to move axially by the cross block 119 at the end. The guide of the axial wedge 112 is provided by the groove processed on the main shaft 114. The axial movement of the axial wedge 112 causes the radial wedge 113 matched with its wedge surface to produce radial movement away from the vertical direction of the main shaft 114 axis, and the two inclined surfaces on the radial wedge 113 lift the fan plate 111 to achieve expansion. At this time, the reel is composed of multiple fan plates 111 and multiple radial wedges 113 to form a whole cylindrical surface. In this way, when the thin strip is coiled, the expansion state is adopted to reduce the indentation when the thin strip is coiled.

[0104] When the reel shrinks, oil flows into the rodless cavity of the expansion and contraction drive cylinder 116, and the piston moves toward the operating side, pushing the core shaft 115 to move. The core shaft 115 relies on the cross stopper 119 at the end to push the axial wedge 112 to move toward the operating side. At this time, the radial wedge 113 that fits with the axial wedge 112 will also produce radial movement in the direction perpendicular to the axis of the main shaft 114 under the pressure of the shrinking spring installed on the fan plate 111, thereby achieving shrinkage.

[0105] When coiling thin strip steel, it is more advantageous to adopt the expanded diameter state, and thin strip steel is more likely to produce indentations. The reel adopts a structure in which the radially inclined wedge 113 and the fan-shaped plate 111 are matched, and the edge of the fan-shaped plate 111 may not be provided with staggered tooth profiles. The entire cylindrical surface formed by the radially inclined wedge 113 and the fan-shaped plate 111 is more complete, which is conducive to the coiling of thin strip steel, and can reduce the indentations on the strip steel close to the reel during coiling. Preferably, the radius of the fan-shaped cylinder 1131 and the outer fan-shaped surface 1111 of the fan-shaped plate 111 are equal, and both are the outer diameters of the drum 11 in the expanded state. When the drum 11 is in the expanded state, that is, the radial wedge 113 moves to the fan-shaped cylinder 1131 and connects with the outer fan-shaped surface 1111 of the fan-shaped plate 111, the fan-shaped cylinder 1131 and the outer fan-shaped surface 1111 of the fan-shaped plate 111 are located on the same cylindrical surface, so that multiple fan plates 111 and multiple radial wedges 113 together form a whole cylindrical surface, which can effectively avoid indentations when coiling thin strip steel.

[0106] Furthermore, the number of radial wedges 113 is at least four, and the number of sector plates 111 is at least four. The expansion state of the drum 11 relies on four sector plates 111 and four groups of radial wedges 113 to form a whole cylindrical surface, ensuring that no indentation will occur when the thin strip is coiled. The drum 11 adopts an octagonal pyramid sector plate drum structure, which can adapt to large thickness changes and ensure the high tension coiling of thick plates and the yield rate of the coiling core of thin plates. In addition, the main shaft 114 of the drum 11 is processed from a whole forging billet, and the sector plates 111 are supported by radial wedges 113, which has good overall rigidity, uniform mass distribution of the drum, high structural strength, and reliable use.

[0107] Coil drive

[0108] Normally, since the thickness of the coiled plate does not change much, the coiling speed generally does not change much, and the matching coiler reducer can only be set to one speed ratio, and the transmission motor power can also be simply determined based on the maximum coiling speed, tension and other related influencing coefficients. However, the coiler reducer suitable for small thickness changes generally uses a single speed ratio. Once the thickness changes in a large range, the required coiling speed will also have a large range of changes. At this time, in order to ensure the coiling process, the ratio of the motor's maximum speed to the base speed is required to be large, but the motor itself has strict restrictions on this, so it is necessary to increase the motor power additionally, which is not conducive to energy saving and cost reduction.

[0109] Therefore, the inventor has made improvements to the coiling drive device: Fig.12 and Fig.13 As shown, the winding drive device 110 includes a motor 131, a transmission device 13 and a gearshift reduction box 12. The motor 131 is connected to the input shaft 123 of the gearshift reduction box 12 through the transmission device 13, and the reel 11 is connected to the output shaft 1215 of the gearshift reduction box 12.

[0110] In order to adapt to the large variation in the exit speed of thin and thick plates and the large variation in the tension required by the two brought about by the large thickness variation, reduce the power of the motor selection, reduce the cost, and combine the characteristics of the coiler, low speed and high tension, high speed and low tension, the inventor has made improvements to the gearbox 12: Fig.18As shown, the gearshift reduction box 12 includes an input shaft 123, an intermediate shaft 125, an output shaft 1215 and a shift fork mechanism 120, wherein the intermediate shaft 125 is connected to the output shaft 1215 through a gear transmission; a first gear 1231 is provided on the input shaft 123, a first idler gear 126 meshing with the first gear 1231 is provided on the intermediate shaft 125, and an angular velocity transmission ratio of the first idler gear 126 to the first gear 1231 is i low; a second gear 124 is provided on the input shaft 123, and a second idler gear 126 meshing with the second gear 124 is provided on the intermediate shaft 125 The angular velocity transmission ratio of the idler gear 127, the second idler gear 127 and the second gear 124 is i high; satisfying: i high>i low; a shift connecting gear 128 located between the first idler gear 126 and the second idler gear 127 is provided on the intermediate shaft 125, and the shift connecting gear 128 is transmission-connected with the internal gear sliding sleeve 1214; the fork mechanism 120 is connected to the internal gear sliding sleeve 1214, and can drive the internal gear sliding sleeve 1214 to switch between transmission connection with the first idler gear 126 and transmission connection with the second idler gear 127.

[0111] The first idler gear 126 can rotate freely relative to the intermediate shaft 125, and can be driven to rotate together with the intermediate shaft 125 through the internal gear sliding sleeve 1214 and the shift connecting gear 128 by being connected to the internal gear sliding sleeve 1214. The second idler gear 127 can rotate freely relative to the intermediate shaft 125, and can be driven to rotate together with the internal gear sliding sleeve 1214 and the shift connecting gear 128 by being connected to the internal gear sliding sleeve 1214. When the internal gear sliding sleeve 1214 is in transmission connection with the first idler gear 126, the shift reduction box 12 is in low gear; when the internal gear sliding sleeve 1214 is in transmission connection with the second idler gear 127, the shift reduction box is in high gear.

[0112] When working, the gear shift reducer 12 can adjust the output speed ratio according to the working conditions. According to the plate thickness specifications, process settings and speed requirements, the working gear of the gear shift reducer 12 is determined, so that the output speed of the motor 131 and the torque output to the reel 11 through the gear shift reducer 12 are reasonably matched, ensuring that the capacity of the motor is fully utilized under the selection of small motor power, better adapting to the actual working needs of high speed and low torque, low speed and high torque, reducing the selected power of the motor 131 and saving costs.

[0113] Specifically, Fig.17 and Fig.19 As shown, the gearshift reduction box 12 includes an upper box body 121, a lower box body 122 and matching support bearings and positioning sleeves; a secondary input gear 129 is provided on the intermediate shaft, and a secondary output gear 1216 meshing with the secondary input gear 129 is provided on the output shaft. Fig.18As shown, the shaft systems cooperate with each other to transmit power, and are assembled in the upper box body 121 and the lower box body 122 to form a whole. Preferably, the output shaft 1215 is a hollow shaft; the first gear 1231 and the input shaft 123 are an integral structure, that is, the input shaft 123 adopts a gear shaft structure. Figure 18-Figure 20 As shown, the shift fork mechanism 120 includes a shift fork hydraulic cylinder 1213 and a shift fork connecting rod mechanism, and the shift fork connecting rod mechanism includes a shift fork 1210 , a shift fork shaft 1211 and a shift fork rocker arm 1212 .

[0114] When it is necessary to work in high gear, the shift fork hydraulic cylinder 1213 retracts, and the shift fork rocker arm 1212 drives the shift fork shaft 1211 to swing, thereby driving the shift fork 1210 to shift the internal gear sliding sleeve 1214, whose internal teeth connect the second idler gear 127 with the external teeth of the shift connecting gear 128. At this time, the torque transmission route is: input shaft 123—second gear 124—second idler gear 127—internal gear sliding sleeve 1214—shift connecting gear 128—intermediate shaft 125—secondary input gear 129—secondary output gear 1216—output shaft 1215—reel 11.

[0115] When it is necessary to work in a low gear, the shift fork hydraulic cylinder 1213 extends out, and the shift fork rocker arm 1212 drives the shift fork shaft 1211 to swing, thereby driving the shift fork 1210 to shift the internal gear sliding sleeve 1214, whose internal teeth connect the first idler gear 126 with the external teeth of the shift connecting gear 128. At this time, the torque transmission route is: input shaft 123—first idler gear 126—internal gear sliding sleeve 1214—shift connecting gear 128—intermediate shaft 125—secondary input gear 129—secondary output gear 1216—output shaft 1215—reel 11.

[0116] The transmission device 13 realizes the power transmission between the motor 131 and the gearbox 12. In one embodiment of the present invention, Fig.12 and Fig.21 As shown, the transmission device 13 includes a drum-type gear coupling 132 with a brake disc and a brake 133. The drum-type gear coupling 132 with a brake disc connects the motor 131 and the input shaft 123 of the gear-shift reduction box 12; the brake disc of the drum-type gear coupling 132 with a brake disc cooperates with the brake 133. The coupling in the transmission device 13 uses a drum-type gear coupling 132 with a brake disc, which connects the motor 131 and the input shaft 123 of the gear-shift reduction box 12, which can ensure the transmission of large torque and reduce the difficulty of installation; the brake disc cooperates with the brake 133, and after the winding is completed, the steel coil can be quickly stopped from rotating to ensure that the tail of the belt is stable in an appropriate position.

[0117] Specifically, the transmission device 13 further includes a protective cover 134. The motor 131 adopts AC frequency conversion control and has good speed regulation performance and overload capacity.

[0118] Unloading push plate device

[0119] The coiler 1 includes a discharge push plate device 14, such as Fig. 22 and Fig.23 As shown, the unloading push plate device 14 includes a push plate 141, a guide rod 144, a guide rod seat 145 and a push plate hydraulic cylinder 146. The guide rod seat 145 is arranged along the axial direction of the reel 11, the guide rod 144 is installed on the guide rod seat 145, the push plate 141 is installed on the guide rod 144, and the push plate hydraulic cylinder 146 is connected to the push plate 141, which can drive the push plate 141 to move along the axial direction of the reel 11, and the push plate 141 can push the steel coil to be unloaded from the reel 11. Fig.12 1 shows an overlay of two positions of the push plate 141. The push plate 141 is used to assist in coil unloading, and cooperates with the coil unloading vehicle to unload the steel coil from the reel 11 to prevent the coil from loosening or collapsing.

[0120] Furthermore, if Fig. 22 and Fig.24 As shown, a lifting plate 142 that can slide up and down is provided on the push plate 141, and a push plate arc surface 1421 that partially wraps around the reel 11 is provided at the lower end of the lifting plate 142; the unloading push plate device 14 includes a fixed lifting seat 143, and the lifting seat 143 is provided with a lifting slope 1431, which is inclined upward along the retreat direction of the push plate 141. When the push plate 141 retreats into place, the lifting plate 142 can rise along the lifting slope 1431.

[0121] By providing the lifting plate 142 and the push plate arc surface 1421, the push plate 141 and the lifting plate 142 can better cooperate with the reel 11, increase the contact with the steel coil when unloading the coil, and reduce the loose coil or collapsed coil; after retreating, the lifting plate 142 rises to avoid scratching the surface of the reel 11, so as to avoid interference with the rotation of the reel 11 during the winding of the new coil. Preferably, during the retreat of the push plate 141, after the push plate 141 passes over the steel coil bearing area of ​​the reel 11, the lifting plate 142 begins to contact the lifting inclined surface 1431, and the push plate 141 continues to retreat one end distance, and the lifting plate 142 completes the lifting.

[0122] Specifically, the guide rod seat 145 and the lifting seat 143 are installed on the gear shift reduction box 12, the guide rod 144 is installed in the guide rod seat 145, and the push plate 141 is installed at the front end. Under the action of the push plate hydraulic cylinder 146, the push plate 141 is constrained by the guide rod 144 and moves linearly along the axis of the reel. After the winding is completed, the push plate 141 cooperates with the unloading car to unload the steel coil from the reel 11 by pushing the side of the steel coil to prevent the coil from loosening or collapsing.

[0123] Furthermore, the lifting plate 142 is provided with a roller that cooperates with the lifting inclined surface 1431. After the roll is unloaded, the push plate 141 moves in the retreat direction, that is, when retreating to the transmission side, the lifting inclined surface 1431 on the lifting seat 143 will contact the roller on the lifting plate 142, so that the lifting plate 142 is lifted to a certain height in the radial direction. At this time, the push plate arc surface 1421 of the lifting plate 142 will be away from the roll surface to avoid scratching the roll surface.

[0124] Upper tail pressure device and lower tail pressure device

[0125] The strip coiling system includes a tail pressing device 4, such as Figure 25-27 As shown, the tail pressing device 4 includes an upper tail pressing device 41 and a lower tail pressing device 42; the upper tail pressing device 41 includes an upper tail pressing cylinder 414 and an upper rubber-coated roller 415 arranged parallel to the reel 11, and the upper tail pressing cylinder 414 can drive the upper rubber-coated roller 415 to move downward and press the tail of the steel coil on the reel 11; the lower tail pressing device 42 includes a lower tail pressing cylinder 424 and a lower rubber-coated roller 425 arranged parallel to the reel 11, and the lower tail pressing cylinder 424 can drive the lower rubber-coated roller 425 to move upward and press the tail of the steel coil on the reel 11.

[0126] The upper tail pressing device 41 and the lower tail pressing device 42 are used to press the tail of the strip after winding onto the steel coil to prevent it from unwinding. Before the winding process is about to end, the upper rubber-coated roller 415 and the lower rubber-coated roller 425 are extended under the action of the hydraulic cylinder and pressed against the steel coil. At this time, as the steel coil rotates, when the tail of the strip swings through the upper rubber-coated roller 415, it is pressed by the lower rubber-coated roller 425 until the V-shaped seat of the unloading car rises to press the tail of the strip, the upper rubber-coated roller 415 and the lower rubber-coated roller 425 are retracted, and the unloading car moves horizontally to unload the coil.

[0127] Specifically, Fig.26 As shown, the upper tail pressing device 41 includes a door-shaped frame 411, an upper tail pressing roller bracket 412 and an upper guide rod 413. The upper tail pressing device 41 is installed on the winding aid 3 through the door-shaped frame 411. When working, the upper tail pressing cylinder 414 extends to drive the upper tail pressing roller bracket 412 to move, and the upper rubber-coated roller 415 installed on it presses against the surface of the steel coil to press the tail of the strip. Fig. 27 As shown, the tail pressing device 42 is a box-type structure installed on the civil engineering. The tail pressing device 42 includes a base 421, a tail pressing roller bracket 422 and a lower guide rod 423. When working, the tail pressing cylinder 424 extends to drive the tail pressing roller bracket 422 to move, and the lower rubber-coated roller 425 installed on it presses against the surface of the steel coil. After the unloading car receives the steel coil and presses the tail, the upper tail pressing device 41 and the lower tail pressing device 42 are reset and wait for the next coil. The upper tail pressing device 41 and the lower tail pressing device 42 are arranged crosswise with the coiling aid 3 and the civil engineering, fully considering the needs of equipment layout, compact and orderly, and reasonable space utilization.

[0128] External support device

[0129] After the coiling process begins, under the action of tension, the cantilever end of the reel 11 tends to swing toward the strip inlet side; at the same time, as the weight of the steel coil gradually increases, the reel 11 also tends to tilt downward. To this end, the inventor has made further improvements to the strip coiling system: Fig.14 As shown, the cantilever end of the reel 11 is provided with a support sleeve 118; Figure 3 and Fig.28 As shown, the strip coiling system includes an external support device 2, which includes a roller seat 22, a first roller 25 for supporting the side of the support sleeve 118, and a second roller 28 for supporting the bottom of the support sleeve 118. The first roller 25 and the second roller 28 are both installed on the roller seat 22, and the roller seat 22 can drive the first roller 25 and the second roller 28 to approach or move away from the support sleeve 118.

[0130] Before the winding process begins, the outer support device 2 moves into place, and the first roller 25 and the second roller 28 are used to support the support sleeve 118 at the cantilever end of the reel 11. The first roller 25 and the second roller 28 are arranged in two force directions, which can improve the stress state of the bearing at the cantilever end of the reel 11 and the bearing inside the gearshift reducer 12.

[0131] Furthermore, if Fig.28 and Fig.30 As shown, the axis of the first roller 25 is inclined from top to bottom toward the inlet side of the reel 11 and is perpendicular to the axis of the reel 11. The roller surface of the first roller 25 includes a first concave arc surface 251 that matches the side wall of the support sleeve 118; the axis of the second roller 28 is arranged in the horizontal direction and is perpendicular to the axis of the reel 11. The roller surface of the second roller 28 includes a second concave arc surface 281 that matches the side wall of the support sleeve 118. In this way, the first roller 25 is a cylindrical concave arc surface roller, which is used to bear the oblique tension component. The second roller 28 is used to offset the vertical force of the reel 11 and the horizontal component of part of the oblique tension, which is beneficial to ensure the support stability. Preferably, as Fig.30 As shown, the roller surface of the second roller 28 also includes a cylindrical surface 282. The second roller 28 is a semi-cylindrical semi-concave arc roller. The design of the semi-cylindrical semi-concave arc surface can ensure that the second roller 28 does not interfere with the reel support sleeve 118 when swinging with the roller seat 22. The arrangement of the two rollers of the external support device 2 fully considers the effects and directions of tension and gravity, and can ensure the stability of the reel during the winding process.

[0132] The roller seat 22 drives the first roller 25 and the second roller 28 to move in various ways, such as moving in the horizontal direction or swinging around a vertical axis. In one embodiment of the present invention, the roller seat 22 adopts a swinging motion around a vertical axis: Fig.28 and Fig.29 As shown, the outer support device 2 includes a fixed base 21, a swing hydraulic cylinder 24 and a hinge pin 23 arranged on the fixed base 21 along the vertical direction. The roller seat 22 is installed on the fixed base 21 through the hinge pin 23. The swing hydraulic cylinder 24 is connected to the roller seat 22 and can drive the roller seat 22 to swing around the hinge pin 23. Fig.29 2 shows an overlay of two positions of the roller mount 22.

[0133] Specifically, in order to adapt to the high tension required for coiling of high-quality steel, the outer support device 2 supporting the cantilever end of the reel 11 adopts a gate-type mechanism. The fixed base 21 and the roller seat 22 are both steel structure welded parts. The roller seat 22 is connected to the pre-welded hinge hole on the fixed base 21 through the hinge pin 23. The cylinder body of the swing hydraulic cylinder 24 is hinged on the fixed base 21, and the cylinder rod is hinged to the roller seat 22. The door-type structure is opened and closed by the extension and contraction of the cylinder rod. Fig.30 As shown, the first roller 25 and the second roller 28 are respectively installed on the roller seat through the roller pin 26 and the roller bracket 27. The roller bracket 27 is connected to the roller seat 22 by bolts, and the first roller 25 and the second roller 28 are connected to the roller pin 26 used as the spindle through the matching bearing. The roller pin 26 is fixed to the roller bracket 27 by the shaft end pressure plate and bolts. The first roller 25 and the second roller 28 can rotate freely, and rolling friction is used instead of sliding friction to reduce the friction between the first roller and the support sleeve and the friction between the second roller and the support sleeve when the roller seat swings.

[0134] The strip steel coiling system can be applied to cold rolling production lines, and is suitable for dual-channel high-quality steel coiling systems with large thickness changes, especially single- and double-frame high-quality steel leveling mills or single-frame rolling mills with rolling functions, which are mainly used for coiling high-quality steel with large thickness changes. The strip steel coiling system can realize dual-channel flat coiling of high-quality steel with rolling functions. In view of the particularity of high-quality steel coiling, a set of high-quality steel coiling systems suitable for large thickness changes is formed by a reasonable combination of the coiler 1, the external support device 2, the coiling aid 3 and the tail pressing device 4. The yield strength of high-quality steel is relatively large, and the strip steel coiling system can coil high-quality steel with a plate thickness of 0.3mm to 3mm.

[0135] The working process of the strip steel coiling system includes: under the action of the auxiliary coiler 3, the strip steel completes the first bite and the second bite on the reel 11; when the strip steel is wound on the reel 11 for 3 to 5 turns, the first swing arm device 33 and the second swing arm device 34 of the auxiliary coiler 3 swing to the retracted state in turn, and the auxiliary coiler body 32 retreats to the waiting position; when the coiling is about to end, the upper rubber-coated roller 415 and the lower rubber-coated roller 425 extend out and abut against the steel coil that is about to be completed to prevent the coil from falling apart; the unloading car lifts the finished coil; the external support device 2 is opened; with the assistance of the unloading push plate device 14, the unloading car moves horizontally to unload the coil.
