Description

Technical Field

[0001] This invention relates to the technical field of shearing equipment for heavy plate production lines in the metallurgical industry, and more specifically, to a steel plate alignment and anti-tipping device and a steel plate alignment method before rolling shearing. Background Technology

[0002] Steel plate alignment is a key process in the control of medium and heavy plate rolling shears. It is mainly used to align the steel plates that are inclined on the conveyor rollers before the fixed-length shear (the shear blades on the side of the steel plate are not perpendicular) to the fixed side. This ensures that the longitudinal side of the steel plate is tightly attached to the guide rollers on the fixed side and is arranged at 90° to the transverse side of the rolling shear blades. This facilitates the rolling shear to perform head cutting, fixed-length cutting, and tail cutting on the steel plate in subsequent operations, thereby improving the cutting quality at both ends of the steel plate and the metal yield.

[0003] After the double-sided shearing equipment cuts the edges, the two sides of the steel plate are relatively flat. However, the head and tail ends still have defects such as burrs and wavy edges. These require subsequent rolling shears to perform three shearing processes: head cutting, length cutting, and tail cutting, to comprehensively improve the quality of the head and tail of the steel plate. When the steel plate is transported to the rolling shear via the conveyor rollers, it may exhibit an inclined arrangement (i.e., the longitudinal direction of the steel plate's side edge is not perpendicular to the transverse direction of the shear blade). If head cutting, length cutting, and tail cutting are performed at this point, the steel plate yield will be significantly reduced, and the workload for subsequent processes such as secondary grinding and machining will increase dramatically, affecting production efficiency and workshop capacity.

[0004] Therefore, in order to improve workshop production efficiency and steel plate yield, before the rolling cutter cuts the steel plate, it is necessary to align the steel plate with the edge to ensure that the longitudinal side of the steel plate is arranged at 90° with the transverse side of the cutting blade of the cutter, so as to prepare for the smooth cutting of the cutter equipment.

[0005] In traditional technology, the lateral movement mechanism of the steel plate alignment anti-tipping device initially used a set of gear and rack mechanisms driven by hydraulic systems on both sides, ultimately using two push rods to move a large push plate laterally to align the steel plates to the edge. However, using a gear and rack mechanism as the lateral movement mechanism has the following drawbacks: Firstly, the gear and rack mechanism requires high precision transmission, demanding high precision in the machining of parts and resulting in high costs; secondly, the gear and rack mechanism is prone to wear and jamming failures in working environments with iron filings and scrap materials, leading to high maintenance frequency.

[0006] Subsequently, based on on-site investigation and problem analysis, the technical personnel improved and upgraded the transverse movement mechanism of the steel plate alignment device. A geared motor was used to drive the sprocket and chain mechanism on both sides of the steel rails, pushing the sliding plate of the transverse trolley base along the track, ultimately achieving edge alignment of the steel plates. The improved sprocket and chain mechanism significantly reduced processing costs and maintenance frequency, but new problems arose: after a period of use, one side of the sprocket and chain mechanism would experience chain slippage or breakage, while the other side continued to drag the steel plate. The tilted steel plate would get stuck on the transport rollers, easily leading to quality defects such as side wear and indentations. Furthermore, the transverse trolley, located above the track, had a relatively high center of gravity, making it prone to instability and tipping during translation, affecting equipment safety and production rhythm. Summary of the Invention

[0007] In response to the aforementioned technical problems, a steel plate alignment and anti-tipping device and a steel plate alignment method are provided before the rolling shear.

[0008] The technical means employed in this invention are as follows:

[0009] A steel plate alignment and anti-tipping device before roll cutting and shearing includes: multiple sets of transverse movement mechanisms and multiple sets of idler roller mechanisms arranged in parallel and parallel, wherein the multiple sets of transverse movement mechanisms and multiple sets of idler roller mechanisms are arranged in parallel and spaced between multiple sets of transport roller tracks.

[0010] The idler mechanism includes a first drive mechanism and a support beam connected to each other. The support beam is located below the elevation of the top surface of the conveyor roller in the initial position. The first drive mechanism is installed on the ground and is used to drive the support beam to lift and lower, so that the steel plate on the conveyor roller is horizontally lifted and removed from the conveyor roller by the support beam.

[0011] The transverse movement mechanism includes a second drive mechanism, a drive-side guide roller, and a fixed-side guide roller. The drive-side guide roller and the fixed-side guide roller are distributed opposite each other on both sides of the conveyor roller track. The fixed-side guide roller is fixed on a second bracket, which is installed on the upper part of the fixed-side roller track base. The drive-side guide roller is connected to the second drive mechanism, which is installed on the ground. The second drive mechanism can move the drive-side guide roller toward or away from the fixed-side guide roller to push the side of the supported steel plate to be close to the fixed-side guide roller, thereby achieving edge alignment.

[0012] Furthermore, the first drive mechanism includes a lifting cylinder, which is installed on the ground. The piston rod output end of the lifting cylinder is connected to one end of the support beam, and the other end of the support beam is installed on the support beam base on the ground. In the initial state, one end of the support beam is lower than the other end and is tilted below the elevation of the top surface of the conveyor roller.

[0013] Furthermore, the second drive mechanism includes a transverse cylinder, a transverse trolley, a support frame one, a track one, a track two, a wheel set one, and a wheel set two. The transverse cylinder is installed on the ground, and the output end of the transverse cylinder is connected to a pin hole provided on one side of the transverse trolley via a pin. The transverse trolley is located between track one and track two, and track one and track two are arranged in parallel. The support frame one is installed above the transverse trolley, and the drive-side guide roller is installed on the support frame one. Wheel set one and wheel set two are installed side by side on the transverse trolley, and both sides of wheel set one and wheel set two are tumblingly connected to track one and track two.

[0014] The transverse cylinder pushes the transverse trolley, which in turn drives the support and the drive side guide roller to move along the track one and track two, so as to align the inclined steel plate with the fixed side guide roller.

[0015] Furthermore, the transverse trolley also includes a boss, a platform, a wheel hole one, and a wheel hole two. The pin hole is opened on one side of the platform, the boss is welded to the top of the platform, and the bracket one is fastened to the top of one side of the upper platform by a bolt assembly. The drive-side guide roller is installed on the boss and the bracket one.

[0016] On the other side of the platform, wheel hole one and wheel hole two are machined. Wheel group one is installed on wheel hole one, and wheel group two is installed on wheel hole two. Both wheel group one and wheel group two have two wheels. The two wheels of wheel group one are respectively rolled and connected to track one and track two. The two wheels of wheel group two are respectively rolled and connected to track one and track two.

[0017] Furthermore, the drive-side guide roller and the fixed-side guide roller have the same structure, and each of the drive-side guide roller and the fixed-side guide roller is provided with 2 sets, with the 2 sets of fixed-side guide rollers and the 2 sets of drive-side guide rollers arranged facing each other on both sides;

[0018] Each set of drive-side guide rollers includes a roller sleeve, a rolling bearing, and a vertical roller shaft. The outer edge of the roller sleeve near the fixed-side guide roller is used to contact the steel plate and push the steel plate to move laterally. The vertical roller shaft fixes the drive-side guide roller as a whole between the boss and the bracket of the traversing trolley through a bolt assembly. The roller sleeve is connected to the vertical roller shaft through the rolling bearing, so that the drive-side guide roller can rotate responsively throughout the traversing process.

[0019] The vertical roller shafts of the two sets of drive-side guide rollers are parallel, and the plane containing the central axis of the two sets of vertical roller shafts is perpendicular to the shearing center line of the rolling cutter.

[0020] Furthermore, the structure and installation method of track one and track two are the same. Track one is welded from five steel plates, including an upper plate, a middle plate, a lower plate, a left plate and a right plate. The upper plate, the middle plate and the lower plate are welded into an I-shaped structure. The upper plate and the lower plate are processed into a groove shape near the wheel assembly to serve as the running channel of the wheel.

[0021] The left and right plates are welded to both sides of the I-shaped structure. Both the left and right plates are machined with multiple sets of pin holes and multiple sets of through holes. The left plate is fixed to the side of the drive-side roller conveyor base by a pin shaft positioning and bolt fastening assembly. The right plate is fixed to the side of the fixed-side roller conveyor base by a pin shaft positioning and bolt fastening assembly.

[0022] Furthermore, the first wheel assembly and the second wheel assembly have the same structure. The first wheel assembly includes a wheel, a horizontal roller shaft, and a second rolling bearing. The horizontal roller shaft passes through wheel holes on both sides of the traverse trolley. Wheels are installed at both ends of the horizontal roller shaft. The wheels on both sides are rolledly connected to the grooves on track one and track two, respectively, so as to realize the horizontal movement of the traverse trolley along the track. The second rolling bearing is set between the horizontal roller shaft and the wheel hole one, so that the horizontal roller shaft rotates dynamically during the entire traverse process.

[0023] The horizontal roller shaft of the second wheel set passes through the wheel holes on both sides of the transverse trolley, and the wheels at both ends of the horizontal roller shaft of the second wheel set are respectively connected to the grooves on the first track and the second track in a rolling connection.

[0024] Furthermore, three sets of rectangular notches are machined on the upper plates of both track one and track two near the fixed side guide roller, namely three sets of rectangular notches one and three sets of rectangular notches two; the three sets of rectangular notches one and three sets of rectangular notches two are arranged in parallel opposite directions along the center line of the roller conveyor, and the center line distance between two adjacent sets of rectangular notches one is S, and the center line distance between two adjacent sets of rectangular notches two is S.

[0025] Each of the first and second tracks is provided with a set of track cover plates. Each track cover plate includes a stop block and a cover plate, and the stop block and the cover plate are welded together.

[0026] Each track has two sets of stops. The four sets of stops are respectively set in two sets of rectangular notches one and two sets of rectangular notches two away from the fixed side guide roller; the gap between the top of the stop and the top of the wheel flange is H, and the gap between the bottom of the stop and the top of the wheel flange is t.

[0027] Each track has one cover plate, and two cover plates are laid on top of three sets of rectangular notches one and three sets of rectangular notches two respectively, and the two cover plates are fastened to the upper plates of track one and track two respectively by bolt assemblies.

[0028] Furthermore, the lateral movement mechanism also includes a limit control system, which includes a mechanical limit device and an electrical limit device;

[0029] The mechanical limiting device includes a first stop, a first impact block, a second impact block, and a second stop. The first and second impact blocks are welded to the side of the platform of the traversing trolley near the side of the first track. The first and second impact blocks are located on the upper part of the first wheel set and the second wheel set, respectively. The distance between the first and second impact blocks is S. The first and second stop blocks are welded to the side of the first track near the side of the traversing trolley. The position of the first stop block is close to point O0, and the position of the second stop block is close to point O4.

[0030] The electrical limiting device includes an electrical limiting component one, an electrical limiting component two, and a sensing plate. The sensing plate is welded to the side of the platform of the traversing trolley near the second track and is located directly above the second wheel set. The initial position of the sensing plate is at point O1, aligned with the electrical limiting component one.

[0031] The electrical limit assembly includes a proximity switch and an angle steel. The proximity switch is fixed on the angle steel, and the angle steel is welded to the upper plate of the track and located at point O1.

[0032] The second electrical limit component includes a second proximity switch and a second angle steel. The second proximity switch is fixed on the second angle steel, and the second angle steel is welded to the upper plate of the second track and is located at point O4.

[0033] The present invention also provides a method for aligning steel plates, using the above-mentioned anti-tipping device for aligning steel plates before rolling shearing, comprising the following steps:

[0034] S1. The steel plate alignment process begins.

[0035] S2, the steel plate reaches the initial position area:

[0036] S21. The motor drives the conveyor rollers to rotate, transporting the steel plate to the area of ​​the anti-tipping device before the rolling shear, preparing for the subsequent steel plate shearing work; at this time, the piston rod of the transverse cylinder is in the retracted state, the transverse trolley is located on the far left, wheel group one and impact block one are located at point O0, wheel group two and impact block two are located at point O1, and the sensing plate is located at point O1, aligned with electrical limit component one;

[0037] S22. The piston rod of the lifting cylinder of the idler roller mechanism is in the retracted state, the entire support beam is below the elevation of the top surface of the conveyor roller, and the support beam is detached from the steel plate.

[0038] S23. After the steel plate reaches the initial value position area, the conveyor roller stops rotating, and the steel plate is placed on the conveyor roller and is in a stationary state.

[0039] S3. Determine the arrangement of the steel plate side edges and the shear blades of the fixed-length shear:

[0040] The steel plate side was detected to be tightly attached to the fixed side guide roller, completing the edge alignment, and arranged at 90° with the cutting blade of the fixed length shear. This is used as the basis for judging whether the steel plate has achieved the target alignment.

[0041] If the judgment result is "yes", then the steel plate has achieved the target alignment requirement and directly proceeds to step S9 to enter the steel plate shearing process;

[0042] If the judgment result is "no", the steel plate has not yet achieved the target alignment requirement, and the next step will be to proceed to step S4 to complete the subsequent operation process;

[0043] S4. The idler roller mechanism rises, and the lower surface of the steel plate is separated from the conveyor roller conveyor:

[0044] The piston rod of the lifting cylinder of the idler roller mechanism gradually extends, pushing the left side of the support beam to move upward along the top hinge point of the support beam base. After the support beam contacts the steel plate, it lifts the steel plate. When the piston rod of the lifting cylinder reaches the maximum stroke position, the support beam is in a horizontal state and above the top surface elevation of the conveyor roller. The lower surface of the steel plate is completely separated from the conveyor roller.

[0045] S5. The transverse movement mechanism drives to the right to align the steel plate to the edge:

[0046] The hydraulic system drives the piston rod of the transverse cylinder to gradually extend, pushing the transverse trolley to move to the right along track one and track two with the help of wheel set one and wheel set two, and driving the drive side guide roller to move together; when the drive side guide roller contacts the steel plate, it pushes the steel plate to move to the right until the side of the steel plate is completely in close contact with the fixed side guide roller to complete the edge alignment.

[0047] S6. Determine whether the steel plate alignment operation has been completed and the target requirements have been met:

[0048] The steel plate side was detected to be tightly attached to the fixed side guide roller, completing the edge alignment, and arranged at 90° with the cutting blade of the fixed length shear. This is used as the basis for judging whether the steel plate has achieved the target alignment.

[0049] If the judgment result is "yes", then the steel plate has achieved the target alignment requirement, and proceed directly to step S7;

[0050] If the judgment result is "no", the steel plate has not yet achieved the target alignment requirement, and the process returns to step S5 to repeat the edge alignment operation.

[0051] The steel plate specification is minimum width B. min At that time, the piston rod of the transverse cylinder reaches the maximum stroke position L. maxAt this time, the traverse trolley is located on the far right, wheel set one and impact block one reach point O3, wheel set two and impact block two reach point O4, the left side of the steel plate is at point O2, the sensing plate is at point O4 and aligned with electrical limit component two, and the entire side of the steel plate is tightly attached to the fixed side guide roller to complete the edge alignment.

[0052] S7. The transverse mechanism moves to the left, returning to the initial position:

[0053] The hydraulic system drives the piston rod of the transverse cylinder to retract gradually, pulling the transverse trolley to move to the left along track one and track two with the help of wheel set one and wheel set two, and driving the drive-side guide roller to move together; when the piston rod of the transverse cylinder is at the minimum stroke position, the transverse trolley is located at the leftmost position, wheel set one and impact block one reach point O0, wheel set two and impact block two reach point O1, the sensing plate is located at point O1 and aligned with electrical limit component one, and the transverse mechanism returns to the initial position; at this time, impact block one contacts the stop frame one to prevent the transverse trolley from hitting the drive-side roller base;

[0054] S8. The idler roller mechanism descends, and the lower surface of the steel plate is in close contact with the top surface of the conveyor roller conveyor:

[0055] The piston rod of the lifting cylinder of the idler roller mechanism gradually retracts, pulling the left side of the support beam downward along the top hinge point of the support beam base, and the support beam gradually separates from the steel plate; when the piston rod of the lifting cylinder is at the minimum stroke position, the support beam is completely separated from the steel plate; at this time, the support beam returns to the initial tilt position and is located below the conveyor roller, and the lower surface of the steel plate falls onto the top surface of the conveyor roller.

[0056] At this point, the steel plate alignment process is complete, and the steel plate shearing process begins.

[0057] S9. The steel plate is transported to the shearing blade area of ​​the fixed-length shear:

[0058] S91. Confirm that the surrounding working environment is safe. The transverse mechanism and the roller mechanism have all returned to their initial positions. The steel plate has completed the edge alignment work. The longitudinal side of the steel plate is arranged at 90° with the transverse side of the fixed-length shear blade. The fixed-length shear blade is fully open.

[0059] S92. The motor drives the conveyor rollers to rotate, transporting the steel plate to the cutting blade area of ​​the fixed-length shear, preparing for the three types of shearing processes of cutting the head, cutting to length, and cutting the tail of the steel plate.

[0060] S10. Perform three types of shearing operations on the steel plate:

[0061] S101. Transport the steel plate head to the fixed-length shearing platform, drive the fixed-length shearing mechanism to move downward, and press down the upper shearing blade to complete the head cutting process of the steel plate; then, drive the fixed-length shearing mechanism to move upward, and the upper shearing blade returns to the initial open state, waiting for the next cutting command.

[0062] S102. After the steel plate has been cut, it is transported to the fixed-length shearing platform. The fixed-length shearing mechanism is driven to move downward. According to production needs, the upper shearing blade performs multiple fixed-length shears on the steel plate. After that, the fixed-length shearing mechanism is driven to move upward, and the upper shearing blade returns to the initial open state, waiting for the next shearing command.

[0063] S103. After the steel plate has been cut to length, it is transported to the cutting blade platform of the cutting blade. The cutting blade mechanism is driven to move downward, and the upper blade presses down to complete the tail cutting process of the steel plate. After that, the cutting blade mechanism is driven to move upward, and the upper blade returns to the initial open state, waiting for the next cutting command.

[0064] At this point, the entire steel plate alignment and shearing process is complete, and the next work cycle begins.

[0065] Compared with the prior art, the present invention has the following advantages:

[0066] 1. This invention uses a hydraulic system as the power source for the transverse movement mechanism to drive the transverse movement trolley to complete the function of aligning the steel plate to the side, thus avoiding technical problems such as high failure rate and frequent maintenance of the gear and rack mechanism.

[0067] 2. The invention cleverly designs an internal track with an "I"-shaped cross section, which serves as the running channel for the wheel assembly. This effectively lowers the center of gravity of the lateral trolley and solves safety hazards such as chain detachment, chain breakage, and equipment tipping.

[0068] 3. By reducing the longitudinal gap value at the rectangular notch of the track cover, this invention eliminates persistent quality problems such as wheel derailment and steel jamming scratches, and improves the stability of the steel plate alignment process and the product yield.

[0069] Based on the above reasons, this invention can be widely applied in fields such as steel plate alignment. Attached Figure Description

[0107] Example 1

[0108] This invention provides a steel plate alignment and anti-tipping device before rolling shearing. Through a novel structural design, it solves the risks and technical problems of the existing technology, such as the instability and tipping of the transverse trolley, chain breakage and failure, and wear and indentation of the steel plate.

[0109] The steel plate alignment and anti-tipping device of the present invention serves as a carrier for realizing the lateral movement driving function of the steel plate, providing a continuous and stable driving force for aligning the steel plate to the edge.

[0110] The device comprises two parts: a traverse mechanism and a roller mechanism, both of which are arranged in a multi-component, parallel configuration, spaced apart between multiple sets of transport rollers. This invention achieves edge alignment of the steel plate on the fixed-side guide roller 6 through the coordinated action of the roller mechanism, the traverse mechanism, and the transport rollers, facilitating subsequent shearing operations on the steel plate by the rolling shear blades.

[0111] The transverse movement mechanism, as the core component of the steel plate alignment anti-tipping device, mainly includes the following parts: transverse movement cylinder 1, transverse movement trolley 2, bracket one 3, drive side guide roller 4, bracket two 5, fixed side guide roller 6, track one 7, track two 8, wheel set one 9, wheel set two 10, track cover plate 11, and limit control system.

[0112] The transverse cylinder 1 is the power source of the transverse mechanism, providing driving force for the transverse movement of the steel plate. The transverse cylinder 1 is installed on the ground. The cylinder head on the right side of the transverse cylinder 1 is connected to the pin hole 201 on the left side of the transverse trolley 2 by a pin. Under the driving action of the transverse cylinder 1, the transverse trolley 2 is pushed, which in turn drives the bracket 1 3 and the drive side guide roller 4 to move to the right along the track 1 7 and the track 2 8, so that the inclined steel plate is aligned with the edge of the fixed side guide roller 6.

[0113] The transverse trolley 2 is located between track 7 and track 8, and mainly includes a pin hole 201, a boss 202, a platform 203, a wheel hole 1 204, and a wheel hole 205. The pin hole 201 and the cylinder head of the transverse cylinder 1 are hinged by a pin. The upper platform 203 is fastened to the bracket 3 near the left side by a bolt assembly. The boss 202 on the top of the platform 203 is positioned by welding. The boss 202 and the bracket 3 are used to install and support the drive side guide roller 4. The right side of the platform 203 and the side near track 7 are welded with impact block 13 and impact block 24. Impact block 13 and impact block 24 are located on the upper part of wheel group 9 and wheel group 20, respectively. Wheel group 9 and wheel group 20 each have two wheels. Wheel holes 1 204 and wheel holes 205 are machined on both sides of the right side of the transverse trolley 2. Wheel holes 1 204 and wheel holes 205 are used to install wheel set 1 9 and wheel set 2 10, ensuring that the four sets of wheels can fall smoothly at the bottom of track 1 7 and track 2 8.

[0114] The bracket 3 is located on the upper part of the platform 203 and is fastened by bolt assembly. The bracket 3 is used to install two sets of drive-side guide rollers 4, providing stable support for the entire lateral movement process of the drive-side guide rollers 4.

[0115] There are two sets of drive-side guide rollers 4. Each set of drive-side guide rollers 4 mainly includes a roller sleeve 401, rolling bearing 402, and vertical roller shaft 403. The roller sleeve 401 and vertical roller shaft 403 are both forgings, which, after heat treatment such as tempering and surface quenching, possess excellent mechanical properties such as high hardness and strong wear resistance. The right outer edge of the roller sleeve 401 directly contacts the steel plate and pushes the steel plate to move laterally. The vertical roller shaft 403 is fixed as a whole between the boss 202 and the bracket 3 by bolt assembly. Two sets of rolling bearings 402 are set between the roller sleeve 401 and the vertical roller shaft 403 to ensure that the drive-side guide rollers 4 can rotate dynamically during the entire lateral movement, thereby eliminating mechanical jamming. The vertical roller shafts 403 of the two sets of drive-side guide rollers 4 are parallel, and the plane containing the central axis of the two sets of vertical roller shafts 403 is perpendicular to the shearing center line of the rolling cutter.

[0116] The second bracket 5 is located on the upper part of the fixed side roller base and is fastened by bolt assembly. The second bracket 5 is used to install two sets of fixed side guide rollers 6. When the steel plates are aligned with the edge, the second bracket 5 provides stable support for the fixed side guide rollers 6.

[0117] There are two sets of fixed-side guide rollers 6 and two sets of drive-side guide rollers 4, and their structures and functions are identical, so they will not be described in detail here. The two sets of fixed-side guide rollers 6 and the two sets of drive-side guide rollers 4 are arranged facing each other on both sides.

[0118] Track 1 (7) and Track 2 (8) have the same structure and installation method. Track 1 (7) is welded from five steel plates: upper, middle, lower, left, and right. The upper, middle, and lower steel plates are welded into an "I"-shaped cross section, and the upper and lower steel plates are processed into a "groove" shape near the four sets of wheels to serve as the running channel for the four sets of wheels, thus lowering the center of gravity of the transverse trolley 2. The left and right steel plates are welded to both sides of the "I"-shaped cross section. Both the left and right steel plates are processed with two sets of pin holes and four sets of through holes. The left steel plate is fixed to the side of the drive-side roller conveyor base by a pin shaft positioning and bolt fastening assembly, and the right steel plate is fixed to the side of the fixed-side roller conveyor base by a pin shaft positioning and bolt fastening assembly.

[0119] On the upper steel plates of track 7 and track 8, near the right side, three sets of rectangular notches 701 and three sets of rectangular notches 801 are machined respectively. The centerline distance between any two adjacent sets of rectangular notches 701 and 801 is S, which facilitates the installation of wheel sets 9 and 10. Each set of two wheels on one side can pass through the adjacent rectangular notches, allowing all four sets of wheels, along with wheel sets 9, 10, the traverse trolley 2, bracket 3, and drive-side guide roller 4, to be installed as a whole at the bottom of the track. A stop block 1101 is installed in each of the two sets of rectangular notches 701 and 801 near the left side. A cover plate 1102 is laid above each of the three sets of rectangular notches 701 and 801, and the two cover plates 1102 are fastened to the upper steel plates of track 7 and track 8 respectively using bolt assemblies.

[0120] There is one set of each of the two tracks, namely track 2 (8) and track 1 (7). Their structural form and function are the same, so they will not be described again.

[0121] Wheel assembly 9 mainly includes wheels 901, horizontal rollers 902, and rolling bearings 903. Wheels 901 and horizontal rollers 902 are forgings, which, after heat treatment such as tempering and surface hardening, possess excellent mechanical properties such as high hardness and strong wear resistance. Wheels 901 directly contact the grooves machined between tracks 7 and 8, enabling the traverse trolley 2 to move horizontally along the tracks. Horizontal rollers 902 pass through wheel holes 204 on both sides of the traverse trolley 2, with one set of wheels 901 installed at each end. Rolling bearings 903 are installed between horizontal rollers 902 and wheel holes 204 to ensure that horizontal rollers 902 can rotate dynamically throughout the traverse process, eliminating mechanical jamming.

[0122] The horizontal roller shaft of wheel set 210 passes through the wheel holes 205 on both sides of the transverse trolley 2, and the wheels at both ends of the horizontal roller shaft of wheel set 210 are respectively connected to the grooves on track 1 7 and track 2 8.

[0123] Wheel set 2 (10) and wheel set 1 (9) each consist of one set, and their structural form and function are identical, so they will not be described in detail here.

[0124] There are two sets of track cover plates 11, one set is installed above track 7 and track 8 respectively;

[0125] The track cover plate 11 mainly includes a stop block 1101 and a cover plate 1102. The stop block 1101 and the cover plate 1102 are welded together. There are two sets of stop blocks 1101 on each track, with one set in each of the two sets of rectangular notches 701 (rectangular notches 801) near the left side. The gap between the top of the stop block 1101 and the top of the wheel flange is H, and the gap between the bottom of the stop block 1101 and the top of the wheel flange is t. The cover plate 1102 is laid on top of the three sets of rectangular notches 701 (rectangular notches 801), and the cover plate 1102 is fastened to the upper steel plate of the track 7 (track 8) by bolt assembly.

[0126] The limit control system consists of two parts: a mechanical limit device and an electrical limit device, providing double protection for the movement of the traverse trolley 2. The mechanical limit device is composed of four parts: a first stop 12, a first impact block 13, a second impact block 14, and a second stop 15. The electrical limit device is composed of three parts: a first electrical limit component 16, a second electrical limit component 17, and a sensor plate 18.

[0127] In the mechanical limiting device, impact block 13 and impact block 24 are welded to the right side of platform 203 and close to track 7, with a distance of S between them. Stop bracket 12 and stop bracket 25 are welded to the side of track 7 and close to the traverse trolley 2, with stop bracket 12 positioned near point O0 and stop bracket 2 positioned near point O4.

[0128] The induction plate 18 is welded to the side steel plate of the platform 203 of the transverse trolley 2, and is located near the track 2 8, directly above the wheel set 2 10.

[0129] The electrical limit device includes an electrical limit component 16, which includes a proximity switch 1601 and an angle steel 1602. The angle steel 1602 is welded to the upper steel plate of the track 2 8 and is located at point O1. The proximity switch 1601 is fixed on the angle steel 1602.

[0130] The electrical limit component 2 17 in the electrical limit device includes a proximity switch 2 1701 and an angle steel 2 1702. The angle steel 2 1702 is welded to the upper steel plate of the track 2 8 and is located at point O4. The proximity switch 2 1701 is fixed on the angle steel 2 1702.

[0131] The anti-tipping solution for the equipment in this invention is implemented as follows:

[0132] 1. Technical principle of equipment tilting: The longitudinal gap value H between the top of the stop block 1101 and the top of the wheel flange is 30mm to 40mm, which is a large gap value.

[0133] When the transverse cylinder 1 drives the transverse trolley 2 to move to the right, the guide roller 4 on the drive side pushes the steel plate to move horizontally together. Since the transverse trolley 2 is located in the "groove" of the "I"-shaped cross section where track 7 and track 8 are located, and uses this as the running channel for the four sets of wheels, the center of gravity of the transverse trolley 2 is low, so the transverse movement of the steel plate is in a stable running state.

[0134] If the horizontally moving trolley 2 continues to move to the right at this point, the following two uncertain situations will occur:

[0135] First, the width of the steel plate is greater than the minimum plate width B. min When wheel set 2 10 reaches point O3 first, although block 2 14 and stop 2 15 have not yet made contact, the lateral trolley 2 cannot continue to move to the right because the drive side guide roller 4 has pushed the steel plate to stick to the fixed side guide roller 6.

[0136] Second, the width of the steel plate = the minimum plate width B min Wheel set 19 reaches point O3, wheel set 210 reaches point O4, the left side of the steel plate is at point O2, the impact block 214 and the stop frame 215 have made contact, and the lateral trolley 2 can no longer move to the right.

[0137] In both of the above states, under the driving force of the transverse cylinder 1, the drive-side guide roller 4 still tends to push the steel plate to the right, and the steel plate applies a reverse thrust to the drive-side guide roller 4 to the left.

[0138] Under this condition, if there is no stop 1101 and the longitudinal gap value H at rectangular notch 1 701 (rectangular notch 2 801) is 30mm to 40mm, the drive side guide roller 4 will drive the bracket 1 3 and the transverse trolley 2 to rotate counterclockwise around the cylinder head hinge point of the transverse cylinder 1, causing wheel set 1 9 and wheel set 2 10 to tilt upward and derail, causing the transverse trolley 2 to tilt to the left and overturn. The right side of the platform 203 will lift up and squeeze the lower surface of the steel plate, resulting in quality problems such as stuck steel and scratched steel plate.

[0139] 2. Description of the anti-tipping scheme for equipment: The longitudinal gap between the bottom of the stop block 1101 and the top of the wheel flange is t, which ranges from 2mm to 3mm, and the gap value is relatively small.

[0140] Regardless of whether the steel plate width is greater than the minimum plate width B min Wheel set 2, 10, reached point O3 first; or perhaps the steel plate width equals the minimum plate width B.min Wheel set 9 reaches position O3, wheel set 10 reaches position O4, and the left side of the steel plate is at position O2. In both of these states, although the lateral trolley 2 cannot continue to move to the right under the driving force of the lateral cylinder 1, the steel plate exerts a reverse thrust to the left on the drive-side guide roller 4. However, due to the presence of the lower stop 1101 of the track cover 11, and the longitudinal gap value t at the rectangular notch 701 (rectangular notch 801) is 2mm to 3mm.

[0141] Even if the limit control system fails completely, when the drive-side guide roller 4 drives the bracket 1 3 and the transverse trolley 2 to rotate counterclockwise around the cylinder head hinge point of the transverse cylinder 1, the right side of the platform 203 will abut against the lower surface of the stop block 1101. The longitudinal gap value of 2mm to 3mm is sufficient to eliminate the risk of accidents such as the transverse trolley 2 tipping over or getting stuck and scratched.

[0142] Example 2

[0143] The steel plate alignment process involves the transverse cylinder 1 driving the transverse trolley 2, which in turn pushes the inclined steel plate to the right by the drive-side guide roller 4. Once the steel plate reaches the fixed-side guide roller 6, it achieves edge alignment, ensuring that the longitudinal direction of the steel plate's side is 90° to the transverse direction of the rolling shear blade. The mechanical and electrical limit devices of the limit control system provide safety assurance for the transverse mechanism 2 to push the inclined steel plate to achieve edge alignment.

[0144] This invention provides a method for aligning steel plates, using the aforementioned anti-tipping device for aligning steel plates before rolling shearing. The specific steel plate alignment process and working method include the following steps:

[0145] The first step is to start the steel plate alignment process.

[0146] The second step is for the steel plate to reach the initial position area.

[0147] The motor drives the conveyor rollers to rotate, transporting the steel plate to the area where the steel plate is aligned with the anti-tipping device before the rolling shear, preparing for the subsequent steel plate shearing operation. At this time, the piston rod of the transverse cylinder 1 is in the retracted state (minimum stroke position), the transverse trolley 2 is located on the far left, wheel set 9 and impact block 13 are located at point O0, wheel set 10 and impact block 14 are located at point O1, and the sensing plate 18 is located at point O1 (aligned with the electrical limit assembly 16).

[0148] The piston rod of the lifting cylinder of the idler mechanism is in the retracted state (minimum stroke position), the entire support beam is below the elevation of the top surface of the conveyor roller, and the support beam is detached from the steel plate.

[0149] After the steel plate reaches the initial position area, the conveyor rollers also stop rotating, and the steel plate is placed on the conveyor rollers and is in a stationary state.

[0150] The third step is to determine the arrangement of the steel plate side and the shear blade of the fixed-length shear.

[0151] The steel plate side was detected to be tightly attached to the fixed side guide roller 6, completing the edge alignment, and arranged at 90° with the cutting edge of the fixed length shear. This is used as the basis for judging whether the steel plate has achieved the target alignment.

[0152] If the judgment result is "yes", then the steel plate has achieved the target alignment requirement, and directly jump to step nine (this result is very unlikely) to enter the steel plate shearing process.

[0153] If the judgment result is "no", then the steel plate has not yet achieved the target alignment requirement, and the next step will be to proceed to the fourth step to complete the subsequent operation process.

[0154] Fourth, the idler roller mechanism rises, and the lower surface of the steel plate is separated from the transport roller track.

[0155] The piston rod of the lifting cylinder of the idler roller mechanism gradually extends, pushing the left side of the support beam to move upward along the top hinge point of the support beam base. After the support beam contacts the steel plate, it lifts the steel plate. When the piston rod of the lifting cylinder reaches the maximum stroke position, the support beam is in a horizontal state and above the top surface elevation of the transport roller, and the lower surface of the steel plate is completely separated from the transport roller.

[0156] Fifth step: The transverse mechanism moves to the right to align the steel plate with the edge.

[0157] The hydraulic system drives the piston rod of the transverse cylinder 1 to gradually extend, pushing the transverse trolley 2 to move to the right along the track 7 and track 8 with the help of the wheel set 9 and the wheel set 10, and driving the drive side guide roller 4 to move together; when the drive side guide roller 4 contacts the steel plate, it pushes the steel plate to move to the right until the side of the steel plate is completely in close contact with the fixed side guide roller 6 to complete the edge alignment.

[0158] The sixth step is to determine whether the steel plate has been aligned and meets the target requirements.

[0159] The steel plate side was detected to be tightly attached to the fixed side guide roller 6, completing the edge alignment, and arranged at 90° with the cutting edge of the fixed length shear. This is used as the basis for judging whether the steel plate has achieved the target alignment.

[0160] If the judgment result is "yes", then the steel plate has achieved the target alignment requirement and will directly proceed to step seven.

[0161] If the judgment result is "no", then the steel plate has not yet achieved the target alignment requirement, and return to step 5 to repeat the edge alignment operation.

[0162] Special note: Only steel plates with a minimum width of B are specified. min Only then can the piston rod of the transverse cylinder 1 reach its maximum stroke position L. maxAt this time, the lateral trolley 2 is located on the far right, wheel set 1 9 and impact block 1 13 reach point O3, wheel set 2 10 and impact block 2 14 reach point O4, the left side of the steel plate is at point O2, the sensing plate 18 is at point O4 (aligned with electrical limit component 2 17), and the entire side of the steel plate is tightly attached to the fixed side guide roller 6 to complete the edge alignment.

[0163] Step 7: The lateral movement mechanism moves to the left and returns to the initial position.

[0164] The hydraulic system drives the piston rod of the transverse cylinder 1 to retract gradually, pulling the transverse trolley 2 to move to the left along track 7 and track 8 using wheel set 9 and wheel set 10, and driving the drive-side guide roller 4 to move together. When the piston rod of the transverse cylinder 1 is at its minimum stroke position, the transverse trolley 2 is located on the far left, wheel set 9 and impact block 13 reach point O0, wheel set 10 and impact block 14 reach point O1, and the sensing plate 18 is located at point O1 (aligned with the electrical limit assembly 16). The transverse mechanism returns to its initial position. At this time, impact block 13 contacts the stop frame 12 to prevent the transverse trolley 2 from hitting the drive-side roller base.

[0165] Step 8: The idler roller mechanism descends, and the lower surface of the steel plate is pressed tightly against the top surface of the transport roller track.

[0166] The piston rod of the lifting cylinder of the idler mechanism gradually retracts, pulling the left side of the support beam downward along the top hinge point of the support beam base, and the support beam gradually separates from the steel plate; when the piston rod of the lifting cylinder is at the minimum stroke position, the support beam is completely separated from the steel plate; at this time, the support beam returns to the initial tilt position and is located below the conveyor roller, and the lower surface of the steel plate falls onto the top surface of the conveyor roller.

[0167] At this point, the steel plate alignment process is complete, and the steel plate shearing process begins.

[0168] Step nine: The steel plate is transported to the cutting edge area of ​​the fixed-length shear.

[0169] First, confirm that the surrounding working environment is safe, that the transverse mechanism and the roller mechanism have returned to their initial positions, that the steel plate has been aligned with the edge, that the longitudinal side of the steel plate is at a 90° angle to the transverse side of the scissor blade, and that the scissor blade is fully open.

[0170] Secondly, the motor drives the conveyor rollers to rotate, transporting the steel plate to the cutting blade area of ​​the fixed-length shear, preparing for the three types of shearing processes: head cutting, fixed-length cutting, and tail cutting.

[0171] Step 10: Perform three types of shearing operations on the steel plate.

[0172] First, the steel plate head is transported to the fixed-length shearing platform, and the fixed-length shearing mechanism is driven downwards, with the upper shear blade pressing down to complete the head-cutting process of the steel plate. Afterwards, the fixed-length shearing mechanism is driven upwards, and the upper shear blade returns to its initial open state, awaiting the next shearing command.

[0173] Next, the steel plate after the head is cut is transported to the fixed-length shearing platform, and the fixed-length shearing mechanism is driven to move downwards. According to production needs, the upper shearing blade performs multiple fixed-length cuts on the steel plate. Afterwards, the fixed-length shearing mechanism is driven to move upwards, and the upper shearing blade returns to the initial open state, waiting for the next cutting command.

[0174] Finally, the steel plate after being cut to length is transported to the cutting blade platform of the cutting blade, and the cutting blade mechanism is driven downwards, with the upper blade pressing down to complete the tail-cutting process of the steel plate. Afterwards, the cutting blade mechanism is driven upwards, and the upper blade returns to its initial open state, waiting for the next cutting command.

[0175] At this point, the entire steel plate alignment and shearing process is complete, and the next work cycle begins.

[0176] This invention is applicable to the rolling shearing equipment of medium and heavy plate production lines, covering various specifications of rolling shearing equipment such as 3000mm, 3500mm, 3800mm, 4200mm, 4300mm, 5000mm, and 5600mm. It is mainly used for edge alignment operation before steel plate shearing to improve yield and overall production capacity.

[0177] This invention is mainly applied to the finishing area of ​​a medium-thick plate production line in the metallurgical industry, specifically on the fixed-length shearing equipment in that area.

[0178] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
