Description

Technical Field

[0001] The present invention relates to the technical field of shearing equipment for a wide and thick plate production line in the metallurgical industry, and in particular to a steel plate alignment and anti-tilting device before rolling shearing and a steel plate alignment method. Background Art

[0002] Steel plate alignment is a key process in the operation process of the medium and thick plate rolling shear. It is mainly used to align the steel plates that are tilted on the transport roller before the cut-to-length shear (the cutting blades of the cut-to-length shear on the side of the steel plate are not vertical) on the fixed side, so that the longitudinal side of the steel plate is close to the fixed side guide roller as a whole, and is arranged at 90° to the cutting blade of the rolling shear horizontally, so that the rolling shear can perform head shearing, cut-to-length shearing and tail shearing on the steel plate in subsequent work, so as to improve the shearing quality and metal recovery rate at both ends of the steel plate.

[0003] After trimming and shearing with the double-sided shearing equipment, the two sides of the entire steel plate are relatively flat, but there are still defects such as burrs and waves at the head and tail. The subsequent rolling-cut fixed-length shears are required to perform three shearing processes on the steel plate, namely trimming the head, cutting the length, and trimming the tail, to comprehensively improve the quality of the head and tail of the steel plate. When the steel plate is transported to the front of the rolling-cut fixed-length shear via the conveyor roller, the steel plate will be tilted (that is, the longitudinal side of the steel plate is not perpendicular to the transverse cutting blade of the fixed-length shear). If the steel plate is trimmed, cut, and trimmed at this time, the yield rate of the steel plate will be greatly reduced, and the workload of secondary grinding and machining of the steel plate in subsequent processes will increase significantly, affecting production efficiency and workshop capacity.

[0004] Therefore, in order to improve the production efficiency of the workshop and the yield rate of steel plates, before the rolling-cut fixed-length shears perform shearing operations on the steel plates, the steel plates need to be aligned against the edges to ensure that the longitudinal side of the steel plate and the transverse cutting blade of the fixed-length shears are arranged at 90°, so as to prepare for the smooth cutting of the subsequent fixed-length shears.

[0005] Traditionally, the transverse movement mechanism of the steel plate alignment and anti-tilt device initially employed a hydraulic system on either side, each driving a rack and pinion mechanism. Ultimately, two push rods drove a large push plate to align the steel plates. However, using a rack and pinion mechanism as the transverse movement mechanism has several drawbacks: First, the high-precision transmission required for rack and pinion components requires high precision machining, resulting in significant cost. Second, rack and pinion mechanisms are prone to wear and jamming in environments with scrap metal and other materials, requiring frequent maintenance.

[0006] Afterwards, the scientific and technical personnel combined on-site investigation and problem analysis to improve and upgrade the transverse mechanism of the steel plate alignment device. They used a reduction motor to drive the sprocket chain mechanism on both sides of the rails, pushing the slide plate of the transverse trolley base to slide along the track, and finally achieving the alignment of the steel plates. The improved sprocket chain mechanism has a significant effect in reducing processing costs and reducing the frequency of maintenance and inspections. However, new problems have arisen: after a period of use, the sprocket chain mechanism will experience chain derailment or chain breakage on one side, while the chain on the other side continues to drag the steel plate. The tilted steel plate is stuck on the transport roller, which is prone to quality defects such as side wear and indentation of the steel plate. In addition, the transverse trolley is located above the track and has a relatively high center of gravity. The transverse trolley is prone to instability during translation and may tip over, affecting equipment safety and production rhythm. Summary of the Invention

[0034] S1. The steel plate alignment process starts;

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

[0036] S21, the motor drives the transport roller to rotate and transport the steel plate to the steel plate alignment anti-tilt device area in front of 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 at the far left, the wheel group 1 and the impact block 1 are at the O0 point, the wheel group 2 and the impact block 2 are at the O1 point, and the sensor plate is at the O1 point, aligned with the electrical limit assembly 1;

[0039] S3. Determine the layout of the steel plate side and the shear blade of the cut-to-length shear:

[0040] Detecting that the side of the steel plate is close to the fixed side guide roller, completing the edge alignment, and is arranged at 90 degrees with the cut-to-length shear blade, is used as the basis for judging whether the steel plate alignment goal has been achieved;

[0041] If the judgment result is "yes", the steel plate has achieved the target alignment requirement, and directly enters 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 process will proceed to step S4 to complete the subsequent operation process;

[0043] S4. The roller mechanism rises and the lower surface of the steel plate leaves the transport roller:

[0044] The piston rod of the lifting cylinder of the roller mechanism gradually extends, pushing the left side of the joist upward along the hinge point at the top of the joist base. The joist contacts the steel plate and lifts the steel plate. When the piston rod of the lifting cylinder reaches the maximum stroke position, the joist is in a horizontal state as a whole and is above the top surface elevation of the transport roller, and the lower surface of the steel plate is completely disengaged from the transport roller.

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

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

[0048] Detecting that the side of the steel plate is close to the fixed side guide roller, completing the edge alignment, and is arranged at 90 degrees with the cut-to-length shear blade, is used as the basis for judging whether the steel plate alignment goal has been achieved;

[0049] If the judgment result is "yes", the steel plate has achieved the target alignment requirement, and directly enters 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 minimum width of the steel plate is B min When the piston rod of the traverse cylinder reaches the maximum stroke position L maxAt this point, the traverse trolley is at the far right, wheel set 1 and bumper 1 have reached position O3, wheel set 2 and bumper 2 have reached position O4, the left side of the steel plate is at position O2, the induction plate is at position O4 and aligned with electrical limit assembly 2, and all sides of the steel plate are in close contact with the fixed side guide rollers to complete the side alignment;

[0052] S7, the traverse mechanism moves left and returns to the initial position:

[0053] The hydraulic system drives the piston rod of the transverse cylinder to gradually retract, pulling the transverse trolley to move to the left along Track 1 and Track 2 with the help of wheel set 1 and wheel set 2, and driving the guide roller on the driving side to move together; when the piston rod of the transverse cylinder is at the minimum stroke position, the transverse trolley is at the far left, wheel set 1 and bumper 1 reach point O0, wheel set 2 and bumper 2 reach point O1, the induction plate is at point O1 and aligned with electrical limit assembly 1, and the transverse mechanism returns to its initial position; at this time, bumper 1 contacts stop frame 1 to prevent the transverse trolley from hitting the drive side roller table base;

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

[0055] The piston rod of the lifting cylinder of the roller mechanism gradually retracts, pulling the left side of the joist downward along the hinge point at the top of the joist base, and the joist gradually separates from the steel plate; when the piston rod of the lifting cylinder is at the minimum stroke position, the joist is completely separated from the steel plate; at this time, the joist returns to its initial tilted position and is located below the transport roller, and the lower surface of the steel plate lands on the top surface of the transport roller;

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

[0057] S9. Steel plates are transported to the cutting blade area of ​​the cut-to-length shear:

[0058] S91. Confirm that the surrounding working environment is safe, the transverse movement mechanism and the roller mechanism have all returned to their initial positions, the steel plate has been aligned to the edge, the longitudinal side of the steel plate and the transverse shear blade of the cut-to-length shear are arranged at 90 degrees, and the upper shear blade of the cut-to-length shear is fully open;

[0059] S92, the motor drives the transport roller to rotate and transport the steel plate to the cut-to-length shearing area, preparing for the three shearing processes of cutting the steel plate, namely, cutting the head, cutting the length and cutting the tail;

[0060] S10, perform three types of shearing operations on the steel plate:

[0061] S101, transporting the head of the steel plate to the shearing blade platform of the fixed-length shear, driving the shearing mechanism of the fixed-length shear to move downward, and pressing the upper shear blade downward to complete the head shearing process of the steel plate; thereafter, driving the shearing mechanism of the fixed-length shear to move upward, and the upper shear blade returns to the initial open state, waiting for the next shearing instruction;

[0062] S102: The cut steel plate is transported to the lower shearing blade platform of the cut-to-length shear, and the shearing mechanism of the cut-to-length shear is driven downward. The upper shearing blade performs multiple cuts on the steel plate according to production needs. Thereafter, the shearing mechanism of the cut-to-length shear is driven upward, and the upper shearing blade returns to its initial open state, awaiting the next cutting instruction.

[0063] S103: The steel plate after the cut-to-length process is transported to the lower shearing blade platform of the cut-to-length shear, and the shearing mechanism of the cut-to-length shear is driven downward, and the upper shearing blade is pressed downward to complete the tail shearing process of the steel plate; thereafter, the shearing mechanism of the cut-to-length shear is driven upward, and the upper shearing blade returns to the initial open state, waiting for the next cutting instruction;

[0066] 1. The present invention adopts a hydraulic system as the power source of the transverse movement mechanism to drive the transverse movement trolley to complete the function of aligning the steel plate against the edge, avoiding technical difficulties such as high failure rate of the rack and pinion mechanism and frequent maintenance and overhaul.

[0109] The steel plate alignment and anti-tilt device of the present invention serves as a carrier for realizing the lateral movement driving function of the steel plate, and provides a driving force with continuous output and stable performance for the edge alignment of the steel plate.

[0110] The device comprises a traverse mechanism and a roller support mechanism, both of which are arranged in parallel and spaced apart between multiple sets of transport rollers. Through the coordinated action of the roller support mechanism, traverse mechanism, and transport rollers, the present invention aligns the steel plate against the fixed-side guide roller 6, facilitating subsequent shearing of the steel plate by the shear blades.

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

[0112] The traverse cylinder 1 is the power source of the traverse mechanism, providing the driving force for the traverse movement of the steel plates. Traverse cylinder 1 is mounted on the ground. The cylinder head on the right side of traverse cylinder 1 is connected to the pin hole 201 on the left side of traverse trolley 2 via a pin. Driven by traverse cylinder 1, traverse trolley 2 is pushed, thereby driving bracket 1 3 and drive-side guide roller 4 to move rightward along track 1 7 and track 2 8, achieving alignment of the tilted steel plates against the fixed-side guide roller 6.

[0113] The transverse trolley 2 is located between track 1 7 and track 2 8, and mainly includes a pin hole 201, a boss 202, a platform 203, a wheel hole 1 204, and a wheel hole 2 205. The pin hole 201 and the cylinder head of the transverse cylinder 1 are hingedly positioned through a pin, and its upper platform 203 is fastened to the bracket 1 3 near the left side through a bolt assembly; the boss 202 located on the top of the platform 203 is positioned by welding, and the boss 202 and the bracket 1 3 are used to install and support the driving side guide roller 4; the right side of the platform 203 and the side close to track 1 7 are welded with a bump block 13 and a bump block 2 14, which are respectively located on the upper part of wheel group 1 9 and wheel group 2 10, and wheel group 1 9 and wheel group 2 10 both have two wheels. Wheel hole 1 204 and wheel hole 2 205 are processed on both sides of the right side of the transverse trolley 2. Wheel hole 1 204 and wheel hole 2 205 are used to install wheel set 1 9 and wheel set 2 10 to ensure that the four sets of wheels can smoothly fall on the bottom of track 1 7 and track 2 8.

[0114] Bracket 1 3 is located on the upper part of platform 203 and is fastened by a bolt assembly. Bracket 1 3 is used to install two sets of driving side guide rollers 4 to provide stable support for the entire lateral movement process of the driving side guide rollers 4.

[0115] There are two sets of drive-side guide rollers 4, each consisting of a roller sleeve 401, a rolling bearing 402, and a vertical roller shaft 403. Both the roller sleeve 401 and the vertical roller shaft 403 are forged components. After heat treatments such as tempering and surface hardening, they possess excellent mechanical properties, including high hardness and strong wear resistance. The right outer edge of the roller sleeve 401 directly contacts the steel plate and propels it laterally. The vertical roller shaft 403 is secured to the drive-side guide rollers 4 between the boss 202 and the bracket 3 via a bolt assembly. Two sets of rolling bearings 402 are positioned between the roller sleeve 401 and the vertical roller shaft 403, ensuring that the drive-side guide rollers 4 rotate with the roller throughout the entire lateral movement, eliminating mechanical jamming. The vertical roller shafts 403 of the two sets of drive-side guide rollers 4 are parallel, with the center axes of the two vertical roller shafts 403 lying in a plane perpendicular to the shear centerline.

[0116] Bracket 2 5 is located on the upper part of the fixed side roller base and is fastened by a bolt assembly. Bracket 2 5 is used to install two sets of fixed side guide rollers 6; when the steel plates are aligned against the edge, bracket 2 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 driving side guide rollers 4, and their structures and functions are the same, so they will not be described in detail.

[0118] The structure and installation method of track 1 7 and track 2 8 are the same. Track 1 7 is welded from five steel plates, namely upper, middle, lower, left and right. The upper, middle and lower steel plates are welded into an "I"-shaped section, and the upper and lower steel plates are processed into a "groove" shape near the four sets of wheels, which serves as the running channel of the four sets of wheels, thereby lowering the center of gravity of the transverse trolley 2; the left and right steel plates are respectively welded on both sides of the "I"-shaped section, and both the left and right steel plates are processed with 2 groups of pin holes and 4 groups of through holes. The left steel plate is fixed to the side of the driving side roller base by a pin shaft positioning and a bolt fastening assembly, and the right steel plate is fixed to the side of the fixed side roller base by a pin shaft positioning and a bolt fastening assembly.

[0119] The upper steel plates of Track 1 7 and Track 2 8 are machined near the right side with three sets of rectangular notches 1 701 and three sets of rectangular notches 2 801, respectively. The centerline distance between two adjacent sets of rectangular notches 1 701 and two adjacent sets of rectangular notches 2 801 is S. This facilitates the installation of Wheel Set 1 9 and Wheel Set 2 10. The two sets of wheels on one side can pass through the two adjacent sets of rectangular notches, allowing the four sets of wheels, along with Wheel Set 1 9 and Wheel Set 2 10, as well as the traversing trolley 2, bracket 1 3, and drive-side guide roller 4, to be installed integrally at the bottom of the track. A set of blocks 1101 is placed within each of the two sets of rectangular notches 1 701 and two sets of rectangular notches 2 801 near the left side. A cover plate 1102 is placed above each of the three sets of rectangular notches 1 701 and three sets of rectangular notches 2 801. The two cover plates 1102 are fastened to the upper steel plates of Track 1 7 and Track 2 8, respectively, via bolt assemblies.

[0120] The number of track 2 8 and track 1 7 is 1 set each, and their structural type and functions are consistent, so they will not be described in detail.

[0121] Wheel set 1 (9) primarily consists of wheels 901, horizontal rollers 902, and rolling bearings 903. Both wheels 901 and 902 are forged components. After heat treatments such as quenching and tempering and surface hardening, they possess excellent mechanical properties, including high hardness and strong wear resistance. Wheels 901 directly contact the grooves machined between rails 1 (7) and 2 (8), enabling horizontal movement of the trolley 2 along the tracks. Horizontal rollers 902 pass through wheel holes 1 (204) on either side of the trolley 2, with a wheel set 901 mounted on each end. Rolling bearings 903 are positioned between horizontal rollers 902 and wheel holes 1 (204), ensuring that horizontal rollers 902 can rotate with the trolley throughout the entire traverse process, eliminating mechanical obstruction.

[0122] The horizontal roller shaft of the second wheel group 10 passes through the second wheel hole 205 on both sides of the transverse trolley 2, and the wheels at both ends of the horizontal roller shaft of the second wheel group 10 are rollingly connected with the grooves on the track 1 7 and the track 2 8 respectively.

[0123] The number of wheel set 2 10 and wheel set 1 9 is 1 set, and their structural type and functions are consistent, so they will not be described in detail.

[0124] There are two sets of track covers 11, one set each above track 1 7 and track 2 8;

[0125] The track cover 11 mainly includes a stopper 1101 and a cover 1102, and the stopper 1101 and the cover 1102 are welded structures; there are two groups of stoppers 1101 on each track, and one group is set in each of the two groups of rectangular notches 701 (rectangular notches 801) on the left side; the gap value between the top of the stopper 1101 and the top of the wheel rim is H, and the gap value between the bottom of the stopper 1101 and the top of the wheel rim is t; the cover 1102 is laid as a whole above the three groups of rectangular notches 701 (three groups of rectangular notches 801), and the cover 1102 is fastened to the upper steel plate of track 1 7 (track 2 8) by a bolt assembly.

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

[0127] In the mechanical limit device, bumper 13 and bumper 2 14 are welded to the right side of platform 203, close to track 1 7. The distance between bumper 13 and bumper 2 14 is S. Bracket 12 and bracket 2 15 are welded to the side of track 1 7, close to the side of the transverse trolley 2. Bracket 12 is located near point O0, and bracket 2 15 is located 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 close to the side of the second track 8 and is located directly above the second wheel set 10.

[0129] The electrical limit assembly 16 in the electrical limit device 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 assembly 17 in the electrical limit device includes a proximity switch 1701 and an angle steel 1702 . The angle steel 1702 is welded to the upper steel plate of the track 8 and is located at point O4. The proximity switch 1701 is fixed on the angle steel 1702 .

[0131] The anti-tilt scheme of the equipment of the present invention is achieved as follows:

[0132] 1. Technical principle of equipment tipping: The longitudinal gap value between the top of the stopper 1101 and the top of the wheel rim is H, which ranges from 30mm to 40mm and is very large.

[0133] When the transverse cylinder 1 drives the transverse trolley 2 to move to the right, the driving side guide roller 4 pushes the steel plate to move horizontally together. Since the transverse trolley 2 is located in the "I"-shaped section "groove" where the track 1 7 and the track 2 8 are located, and it is used 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 traverse trolley 2 continues to move right, the following two uncertain situations will occur:

[0135] First, the steel plate width is greater than the minimum plate width B min When the second wheel group 10 first reaches the O3 point, although the second collision block 14 and the second stop frame 15 have not yet contacted, the driving side guide roller 4 has pushed the steel plate close to the fixed side guide roller 6, and the transverse trolley 2 cannot continue to move to the right;

[0136] Second, the width of the steel plate = the minimum plate width B min , wheel group 1 9 reaches point O3, wheel group 2 10 reaches point O4, the left side of the steel plate is at point O2, the bumper 2 14 and the stopper 2 15 have already come into contact, and the traverse trolley 2 cannot continue to move to the right;

[0137] In the above two states, under the driving force of the transverse cylinder 1, the driving side guide roller 4 still pushes the steel plate to move to the right, and the steel plate applies a reverse thrust to the driving side guide roller 4 to the left.

[0138] Under this working condition, if there is no block 1101 and the longitudinal gap value H at the rectangular notch 1 701 (rectangular notch 2 801) is 30mm~40mm, the driving side guide roller 4 drives the bracket 1 3 and the transverse trolley 2 to rotate counterclockwise around the cylinder head hinge of the transverse cylinder 1, causing the wheel group 1 9 and the wheel group 2 10 to tilt upward and derail, causing the transverse trolley 2 to tip over to the left, and the right part of the platform 203 is lifted up to squeeze the lower surface of the steel plate, resulting in quality problems such as steel jamming and scratches on the steel plate.

[0139] 2. Description of the solution for preventing the equipment from tipping over: The longitudinal gap value between the bottom of the stopper 1101 and the top of the wheel rim is t, which is in the range of 2 mm to 3 mm and is relatively small.

[0140] Whether the steel plate width > minimum plate width B min , wheel set 2 10 reaches O3 first; or the steel plate width = minimum plate width Bmin , wheel set 1 9 reaches position O3, wheel set 2 10 reaches position O4, and the left side of the steel plate is at position O2. In both of these states, although the traverse trolley 2 cannot continue to move rightward due to the driving force of the traverse cylinder 1, the steel plate exerts a reverse thrust to the left on the driving-side guide roller 4. However, due to the presence of the lower block 1101 of the track cover 11 and the longitudinal clearance value t at the rectangular notch 1 701 (rectangular notch 2 801) of 2mm to 3mm.

[0141] Even if the limit control system fails completely, when the driving side guide roller 4 drives the bracket 3 and the transverse trolley 2 to rotate counterclockwise around the cylinder head hinge of the transverse cylinder 1, the right part of the platform 203 will rest against the lower surface of the block 1101. The longitudinal clearance value of 2mm to 3mm is sufficient to eliminate the risk of accidents such as the transverse trolley 2 tipping over, steel jamming and scratches.

[0142] Example 2

[0143] The so-called steel plate alignment process involves using the transverse cylinder 1 to drive the transverse trolley 2, which in turn is pushed to the right by the drive-side guide roller 4. When the steel plate reaches the fixed-side guide roller 6, it is aligned against the edge, ensuring that the longitudinal edge of the steel plate is aligned at a 90-degree angle to the shear blade. The mechanical and electrical limit devices of the limit control system provide safety for the transverse mechanism 2 to push the tilted steel plate to achieve edge alignment.

[0144] The present invention provides a steel plate alignment method, using the above-mentioned steel plate alignment and anti-tilt device before rolling shearing. The specific steel plate alignment process and working method include the following steps:

[0145] In the first step, the steel plate alignment process begins.

[0146] In the second step, the steel plate reaches the initial position area.

[0147] The motor drives the transport rollers to rotate, transporting the steel plate to the steel plate alignment and anti-tilt device area in front of the rolling shear, preparing for subsequent steel plate shearing. At this time, the piston rod of the transverse cylinder 1 is retracted (minimum stroke position), the transverse trolley 2 is at the far left, wheel assembly 1 9 and bumper 1 13 are at point O0, wheel assembly 2 10 and bumper 2 14 are at point O1, and the sensor plate 18 is at point O1 (aligned with electrical limit assembly 16).

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

[0149] After the steel plate reaches the initial value position area, the transport roller also stops rotating, and the steel plate is placed on the transport roller and is in a stationary state.

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

[0151] It is detected that the side edge of the steel plate is close to the fixed side guide roller 6, the edge alignment is completed, and it is arranged at 90° with the fixed-length shear blade. This is used as the basis for judging whether the steel plate alignment goal is achieved.

[0152] If the judgment result is "yes", the steel plate has achieved the target alignment requirement and directly jumps to step 9 (the probability of this result is very small) to enter the steel plate shearing process.

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

[0154] In the fourth step, the roller mechanism rises and the lower surface of the steel plate leaves the transport roller.

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

[0156] Step 5: Drive the transverse mechanism to the right to align the steel plate to 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 1 7 and track 2 8 with the help of wheel group 1 9 and wheel group 2 10, and driving the driving side guide roller 4 to move together; when the driving side guide roller 4 contacts the steel plate, it pushes the steel plate to move horizontally to the right until all the side edges of the steel plate are close to the fixed side guide roller 6 to complete the edge alignment.

[0158] The sixth step is to determine whether the steel plate has completed the alignment operation and meets the target requirements.

[0159] It is detected that the side edge of the steel plate is close to the fixed side guide roller 6, the edge alignment is completed, and it is arranged at 90° with the fixed-length shear blade. This is used as the basis for judging whether the steel plate alignment goal is achieved.

[0160] If the judgment result is "yes", the steel plate has achieved the target alignment requirement and will directly enter the seventh step.

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

[0162] Special note: Only the steel plate specification is the minimum width B min When the piston rod of the traverse cylinder 1 reaches the maximum stroke position L maxAt this time, the transverse trolley 2 is at the far right, the wheel group 1 9 and the bumper 13 reach the O3 position, the wheel group 2 10 and the bumper 2 14 reach the O4 position, the left side of the steel plate is at the O2 position, the induction plate 18 is at the O4 position (aligned with the electrical limit assembly 2 17), and the side edges of the steel plate are all close to the fixed side guide roller 6 to complete the edge alignment.

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

[0164] The hydraulic system gradually retracts the piston rod of traverse cylinder 1, pulling traverse trolley 2 to the left along tracks 1-7 and 2-8 with the aid of wheel assembly 1-9 and wheel assembly 2-10, and driving guide roller 4 along with it. When the piston rod of traverse cylinder 1 is at its minimum stroke, traverse trolley 2 is at its leftmost position, wheel assembly 1-9 and bumper 1-13 reach position O0, wheel assembly 2-10 and bumper 2-14 reach position O1, and sensor plate 18 is at position O1 (aligned with electrical limit assembly 1-16), and the traverse mechanism returns to its initial position. At this point, bumper 1-13 contacts retaining frame 1-12, preventing traverse trolley 2 from colliding with the drive-side roller table base.

[0165] In the eighth step, the roller mechanism descends and the lower surface of the steel plate is in close contact with the top surface of the transport roller.

[0166] The piston rod of the lifting cylinder of the roller mechanism retracts gradually, pulling the left side of the joist downward along the hinge point at the top of the joist base, and the joist gradually separates from the steel plate; when the piston rod of the lifting cylinder is in the minimum stroke position, the joist is completely separated from the steel plate; at this time, the joist returns to its initial inclined position and is located as a whole below the transport roller, and the lower surface of the steel plate falls on the top surface of the transport roller.

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

[0168] In the ninth step, the steel plate is transported to the cutting blade area of ​​the cut-to-length shear.

[0169] First, make sure the surrounding working environment is safe, the transverse movement mechanism and the roller mechanism have all returned to their initial positions, the steel plate has been aligned to the edge, the longitudinal side of the steel plate and the transverse blade of the fixed-length shear are arranged at 90°, and the upper blade of the fixed-length shear is fully open.

[0170] Secondly, the motor drives the transport roller to rotate and transport the steel plate to the cut-to-length shear blade area, preparing for the three types of shearing processes: cutting the head, cutting the length, and cutting the tail of the steel plate.

[0171] The tenth step is to perform three types of shearing operations on the steel plate.

[0172] First, the head of the steel plate is transported to the lower shearing blade platform of the cut-to-length shear, and the shearing mechanism of the cut-to-length shear is driven downward, and the upper shear blade is pressed down to complete the head shearing process of the steel plate. After that, the cut-to-length shear mechanism is driven upward, and the upper shear blade returns to its initial open position, waiting for the next cutting instruction.

[0173] Next, the cut steel plate is transported to the lower shearing blade platform of the cut-to-length shear, which drives the shearing mechanism downward. The upper shearing blade then performs multiple cuts on the steel plate according to production needs. Afterwards, the shearing mechanism is driven upward, and the upper shearing blade returns to its initial open position, awaiting the next cutting instruction.

[0174] Finally, the cut-to-length steel plate is transported to the lower shearing blade platform of the cut-to-length shear, which drives the cut-to-length shear mechanism downward, pressing the upper shear blade downward to complete the tail shearing process. Afterwards, the cut-to-length shear mechanism is driven upward, and the upper shear blade returns to its initial open position, awaiting the next cutting instruction.

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

[0176] The present invention is applicable to rolling shearing equipment of medium and thick plate production lines, covering various specifications of rolling shearing equipment such as 3000mm, 3500mm, 3800mm, 4200mm, 4300, 5000mm, and 5600mm. It is mainly used for edge alignment operations before steel plates are sheared to improve the yield rate and overall line production capacity.

[0177] The present invention is mainly used in the finishing area of ​​a medium and thick plate production line in the metallurgical industry, and is specifically implemented on the cut-to-length shearing equipment in this area.

[0178] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
