Description

Technical Field

[0001] The present invention relates to the technical field of shearing equipment for wide and thick plate production lines in the metallurgical industry, and in particular to a waste anti-jamming device and a working method for a rolling shear. Background Art

[0002] The waste anti-jamming device is an important component of the rolling shear equipment and is located at the bottom of the rolling shear. Its main function is to complete the shearing processes such as cutting the head, cutting the length and cutting the tail of the steel plate through the lifting roller and the upper and lower shear blades of the rolling shear. At the same time, it facilitates the smooth sliding of the cut head waste and the cut tail waste into the waste collection and transportation device below it, providing protection for the shearing efficiency and annual production capacity of the wide and thick plate production line.

[0003] In the finishing area of ​​the wide and thick plate production line, steel plates require a roller-type cut-to-length shear and a scrap anti-jamming device to coordinate and complete the shearing processes, including head trimming, cut-to-length, and tail trimming, to comprehensively improve the quality of the head and tail of the steel plates. This area involves two tasks: steel plate transportation and steel plate shearing. During steel plate transportation, the lifting roller is raised, and its roller assembly cooperates with the steel plate to pass through the upper and lower shear blades. When the steel plate is sheared, the lifting roller is lowered, and the upper and lower shear blades cooperate to complete the shearing of the steel plate. After the steel plate is cut to length, it is transferred to the next process via the roller assembly of the lifting roller. After the steel plate is cut to length and tail trimming, the scrap slides through the gap between the lifting roller frame and the roller-type cutter base to the scrap collection and transportation device and is transferred to the scrap pit. This cycle repeats until all steel plate shearing is completed.

[0004] In this area, the steel plate needs to continuously cross the upper and lower shear blades, and faces complex working conditions such as mechanical vibration, iron oxide scale shedding, and cooling water invasion. The lifting cylinder of the first waste anti-jamming device poses a severe test. The second waste anti-jamming device is located in the civil engineering pit at the bottom of the rolling shear. Due to the narrow space, equipment maintenance is difficult and time-consuming.

[0005] In traditional technology, the multiple roller assemblies of the lifting roller adopt a centralized transmission type, which takes up a lot of space and is difficult to maintain. Once a group of roller assemblies fails, the entire lifting roller will stop working, and the equipment will be inefficient. The detection elements of the two extreme positions of the highest and lowest positions of the lifting cylinder are arranged vertically and linearly, which is difficult to install and adjust in a small space and has low detection accuracy. The cylinder head of the lifting cylinder is directly connected to the bottom of the roller frame. The steel plate and equipment load directly act on the cylinder head of the lifting cylinder. There is no buffer space, which affects the service life of the lifting cylinder. When shearing the steel plate, if the lifting roller fails to descend due to an erroneous operation, the excessive impact load may cause the lifting cylinder to fail or even be directly scrapped. In addition, some incoming steel plates have extreme conditions such as irregular shapes and out-of-tolerance sizes. Once the size of the cut head and tail waste is too large, it will be stuck in the gap between the lifting roller frame and the rolling shear base, and cannot slide smoothly to the waste collection and transportation device. Manual cleaning of the waste is required. In a narrow space, manual cleaning is difficult and there are many unsafe factors such as falling into the foundation pit and mechanical injuries.

[0006] Therefore, it is necessary to develop a device to prevent waste from getting stuck in rolling shears, and to solve the risks and technical difficulties existing in the existing technology, such as easy equipment failure, difficulty in cleaning stuck waste, and difficulty in maintenance and lifting, through equipment structure innovation and process optimization.

[0033] The present invention also provides a method for operating a waste anti-jamming device for a rolling shear, comprising the following steps:

[0034] S1. The steel plate arrives at the entrance of the rolling shear: The steel plate is transported to the entrance area of ​​the rolling shear by the transport roller in front of the rolling shear equipment, preparing for subsequent steel plate transportation, shearing and waste cleaning. At this time, the head and tail ends of the steel plate along the entire length direction have irregular shapes, and the waste at the head and tail of the steel plate needs to be cut off, and the fixed length shearing of the middle part of the steel plate is completed;

[0035] S2. Check the working conditions of the rolling shear and waste anti-jamming device:

[0036] a. Check whether the lifting cylinder and the traverse cylinder of the waste anti-jamming device are in the minimum stroke position;

[0037] b. Check whether the cutting blade on the rolling shear is in the open state;

[0038] S3. Lifting of the waste anti-jamming device: The hydraulic system drives the piston rod of the lifting cylinder to gradually extend, pushing the transmission side frame and the fixed side frame through the lifting mechanism, thereby driving the roller assembly 1 and the roller assembly 2 to move upward as a whole. After the lifting stroke H, the piston rod of the lifting cylinder reaches the maximum stroke position, completing the lifting of the waste anti-jamming device;

[0039] S4. Preparation for steel plate shearing includes:

[0040] a. Steel plate transportation work: simultaneously drive the transport roller in front of the rolling shear equipment, roller assembly 1 and roller assembly 2 of the waste anti-jamming device;

[0041] b. The steel plate passes through the upper shear blade and the lower shear blade;

[0042] c. Lowering of the waste anti-jamming device: The hydraulic system drives the piston rod of the lifting cylinder to gradually retract, pulling the transmission side frame and the fixed side frame through the lifting mechanism, thereby driving the roller assembly 1 and the roller assembly 2 to move downward as a whole. When the piston rod of the lifting cylinder reaches the minimum stroke position, the lowering of the waste anti-jamming device is completed;

[0043] S5. Steel plate cutting, cutting to length, and cutting to tail: including:

[0044] a. The head of the steel plate passes through the upper and lower shear blades, driving the shear blade locking cylinder to press the upper shear blade down. The upper and lower shear blades work together to complete the shearing of the steel plate. The head waste slides smoothly to the waste collection and transportation device through the gap between the transmission side frame, the left side of the fixed side frame and the side wall of the rolling shear base;

[0045] b. Repeat steps S3 to S4 until the middle of the steel plate passes through the upper and lower shear blades; drive the shear blade locking cylinder to press down the upper shear blade, and the upper and lower shear blades together complete the steel plate's cut-to-length work N times until the cut-to-length work is completed;

[0046] c. Repeat steps S3 to S4 to allow the tail of the steel plate to pass through the upper and lower shear blades; drive the shear blade locking cylinder to press down the upper shear blade, and the upper and lower shear blades work together to complete the shearing of the tail of the steel plate. The tail waste slides smoothly through the gap between the transmission side frame, the left side of the fixed side frame and the side wall of the rolling shear base to the waste collection and transportation device;

[0047] d. Drive the shear blade locking cylinder to lift the upper shear blade to keep it in the open state;

[0048] S7: The entire steel plate is sheared and waits for the next shearing instruction.

[0049] If there is no cutting instruction, it will directly enter the next working cycle.

[0050] Furthermore, in step a and step c in S5, it is also necessary to determine whether a waste material blocking failure occurs, and the specific steps include:

[0051] S01. After the head and tail cutting work is completed, determine whether there is any waste blocking phenomenon:

[0052] If the judgment result is "yes", go directly to step S02;

[0053] If the judgment result is "No", go to step S05;

[0054] S02. Shift the waste anti-jamming device to the right: The hydraulic system drives the piston rod of the lateral movement cylinder to gradually extend, pulling the transmission side frame and the fixed side frame through the lateral movement mechanism, thereby driving the roller assembly 1 and the roller assembly 2 to move right as a whole. After the lateral movement stroke S, the piston rod of the lateral movement cylinder reaches the maximum stroke position, completing the rightward lateral movement of the waste anti-jamming device.

[0055] S03, eliminating waste jam: After step S02 is completed, the gap between the transmission side frame, the left side of the fixed side frame and the side wall of the rolling shear base increases by S, and both the head and tail waste can slide smoothly to the waste collection and transportation device, completing the waste cleaning work;

[0056] S04. The waste material anti-jamming device moves left and returns to the minimum stroke position: The hydraulic system drives the piston rod of the traverse cylinder to gradually retract, pushing the transmission side frame and the fixed side frame through the traverse mechanism, thereby driving the roller assembly 1 and roller assembly 2 to move left as a whole. When the piston rod of the traverse cylinder reaches the minimum stroke position, the waste material anti-jamming device returns to its initial position on the left.

[0057] S05. The transportation, shearing and waste jam elimination of the entire steel plate are all completed and enter the next work cycle.

[0058] Compared with the prior art, the present invention has the following advantages:

[0059] 1. The present invention increases the gap between the left side of the frame and the side wall of the rolling shear base through the transverse movement mechanism, thereby achieving safe and rapid cleaning of stuck waste and providing convenience for equipment maintenance and lifting replacement.

[0060] 2. A crank mechanism is set between the lifting mechanism and the frame, which plays a buffering role through the rolling hinge point, and can effectively reduce the load impact of equipment lifting and steel plate transportation.

[0061] 3. The induction plate of the lifting limit control system adopts a "Z"-shaped structure, which enables the parallel installation of two detection switches, reduces the difficulty of disassembly and assembly, and improves the detection accuracy in a small space.

DETAILED DESCRIPTION

[0079] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0081] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0082] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​described in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0083] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0084] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0085] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0086] like Figure 1-15 As shown, the present invention provides a waste material anti-jamming device and working method for a rolling shear.

[0087] As a key component of the rolling shear system, the scrap anti-jam device primarily performs three core functions: first, it facilitates the transport and shearing of steel plates; second, it facilitates the smooth sliding of scrap to the scrap collection and transportation device; and third, it facilitates equipment maintenance and lifting. This technology utilizes the synergistic effects of the upper and lower shear blades of the rolling shear, the scrap anti-jam device, and the scrap collection and transportation device to achieve the three core functions of the scrap anti-jam device, including the transport, shearing, and scrap sliding of steel plates.

[0088] In order to realize the core function of the waste anti-jamming device, the following main components need to be configured: transmission side frame 1, fixed side frame 2, roller assembly 1 3, crossbeam 4, cover plate 5, side bracket 6, transverse movement mechanism 7, lifting mechanism 8, track group 1 9, track group 2 10, roller assembly 2 11, crank frame mechanism 12, lifting limit control system 13, and transverse movement limit control system 14.

[0089] The scrap anti-jamming device pushes the crank frame mechanism 12 through the lifting mechanism 8, which in turn drives the transmission side frame 1 and the fixed side frame 2, completing the lifting and lowering of the roller assembly 1 3 and the roller assembly 2 11, realizing the steel plate transportation function. Its lifting stroke is H. When the steel plate passes through the upper and lower shear blades of the roller shearing device, the steel plate is sequentially cut, cut to length, and cut to the tail, realizing the shearing function.

[0090] The waste anti-jamming device is driven by the transverse mechanism 7 to drag the transmission side frame 1 and the fixed side frame 2, and then drive the roller assembly 1 3 and the roller assembly 2 11. The whole device completes the transverse movement along the track group 1 9 and the track group 2 10 to realize the waste removal function. The transverse movement stroke is S.

[0091] The lifting limit position of the waste anti-jamming device is achieved by the lifting limit control system 13, and the lateral limit position is achieved by the lateral limit control system 14.

[0092] The transmission side frame 1 and the fixed side frame 2 are both welded structures. Four sets of crossbeams 4 are installed between the transmission side frame 1 and the fixed side frame 2. These crossbeams 4 are welded structures, with their ends bolted to the side walls of the transmission side frame 1 and the fixed side frame 2. Together, the transmission side frame 1, the fixed side frame 2, and the crossbeams 4 form the supporting components of the waste anti-jamming device, designed to withstand vertical and impact loads from components such as the steel plate, roller assembly 3, cover plate 5, side brackets 6, and roller assembly 11.

[0093] The transmission side frame 1 is located near the reduction motor 301, and the fixed side frame 2 is located away from the reduction motor 301. The left sides of the transmission side frame 1 and the fixed side frame 2 are close to the upper and lower cutting blades of the rolling shear, and there is a gap between them and the side wall of the rolling shear base to facilitate the sliding of the head and tail waste.

[0095] When the waste anti-jamming device needs to be inspected and hoisted, the lifting mechanism 8 can be disengaged to allow the slide plate 203 to smoothly fall into the groove on the left side of the positioning plate 202, providing safety protection and stable support for the entire frame.

[0105] The lifting mechanism 8 is located below the transmission side frame 1 and the fixed side frame 2, with the crank frame mechanism 12 at its top. The lifting mechanism 8 primarily comprises a lifting cylinder 801, a second base 802, a cylinder support 803, a second pin 804, and a second shaft end stop 805. The lifting cylinder 801 serves as the power source, providing the driving force for raising and lowering the waste anti-jamming device. The head and tail ends of the lifting cylinder 801 are connected to the crank frame 1201 and the cylinder support 803 via the second pin 804, respectively. A second shaft end stop 805 is provided on one side of the second pin 804. The cylinder support 803 is bolted to the top left side of the second base 802. The top right side of the second base 802 is also bolted to the second bearing seat 1204.

[0106] The lifting mechanism 8 breaks the drawbacks of previous traditional technologies. The head of the lifting cylinder 801 is connected to the crank frame 1201 through the pin shaft 804, and is in contact with the bottom of the transmission side frame 1 and the fixed side frame 2 through the roller shaft 1213, forming a rolling hinge and having a buffering function, which can effectively reduce the load impact of equipment lifting and steel plate transportation.

[0107] The lifting mechanism 8 consists of two groups. When lifting, the steel plate contacts the top of roller assembly 1 3 and roller assembly 2 11, which can realize steel plate transportation; when lowering, the steel plate is separated from roller assembly 1 3 and roller assembly 2 11, and the upper and lower shear blades of the rolling shear equipment are cooperated to realize steel plate shearing.

[0108] The track group 9 is located below the fixed side frame 2, and mainly includes a rail 901, a base 902, a baffle 903, a pressure plate 904, a roller shaft 905, a sealing ring 906, a spacer ring 907, a shaft end baffle 908, an end cover 909, a ball bearing 910, and a flat roller 911.

The rail 901 is fixed above the base 902 by bolts; the roller shaft 905 is provided with a plurality of sprockets, and the sprockets are fixed to the base 902 by bolts. 05 is welded and fixed to the inner hole of the steel plate on the side wall of the fixed side frame 2 on the left side, and a flat roller 911 is installed on the right side of the roller shaft 905; two groups of ball bearings 910 are arranged inside the flat roller 911, and a spacer ring 907 is arranged between the two groups of ball bearings 910, a sealing ring 906 is installed on the left side of the two groups of ball bearings 910, and the right side of the two groups of ball bearings 910 is positioned by the shaft end baffle three 908; below the flat roller 911 is the steel rail 901, and the flat roller 911 rolls and moves laterally above the steel rail 901 around the roller shaft 905 and the ball bearing 910.

[0109] Track group 2 10 is located below the movable side frame 1. Except for the second rail 1001 and the groove roller 1011, the other structural types and main functions of track group 2 10 are similar to those of track group 1 9 and will not be repeated here.

[0110] Track assembly 1 9 and track assembly 2 10 serve as transverse channels for the fixed side frame 2 and the transmission side frame 1. They work together to facilitate the lateral movement of the waste anti-jam device, increasing the clearance between the left sides of the transmission side frame 1 and the fixed side frame 2 and the side wall of the roller shear base, enabling rapid waste removal. They also provide ample operating space for the waste anti-jam device during equipment maintenance.

[0111] Track set 1 (9) is equipped with three sets of flat rollers (911) at the free end, while track set 2 (10) is equipped with three sets of grooved rollers (1011) at the fixed end. This structure ensures smooth sliding over rails 1 (901) and 1 (1001), eliminating any jamming during lateral movement of the waste anti-jamming device. A lateral limit control system (14) is installed below the fixed side frame (2), near track set 1 (9).

[0112] The roller assembly 2 11 is located at the top of the transmission side frame 1 and the fixed side frame 2. Except for the transmission part (reduction motor 2 1101, protective cover 1102, universal joint 1103, coupling 1104, motor base 1105), the other structural types and main functions of the roller assembly 2 11 are similar to those of the roller assembly 1 3. Both are driven by a single reduction motor and will not be repeated here.

[0113] Roller assembly 2 11 is located at the outermost end of the waste material anti-jam device on the exit side. Its transmission components (gear motor 2 1101, protective cover 1102, universal joint 1103, coupling 1104, and motor base 1105) differ significantly from gear motor 1 301 of roller assembly 1 3. This is primarily due to the fact that the waste material anti-jam device of this technology has a transverse movement function with a transverse movement stroke of S. This structural design is designed to prevent the waste material anti-jam device from colliding with adjacent equipment on the exit side of the device when it moves to the right to its maximum travel position T2.

[0114] The crank mechanism 12 is located below the transmission side frame 1 and the fixed side frame 2, and mainly includes a crank frame 1201, a pin shaft 3 1202, a shaft end baffle 4 1203, a bearing seat 2 1204, a self-lubricating sleeve 1205, a synchronous shaft 1206, a key 1207, an oil cup 1208, a baffle 2 1209, a gasket group 2 1210, a sealing ring 2 1211, a pressure cover 3 1212, a roller 1213, a guide sleeve 1214, and a ball bearing 2 1215. There are two groups of crank frames 1201, one group under the transmission side frame 1 and one under the fixed side frame 2; two groups of cranks A key 1207 connects the center of crank frame 1201 to the synchronous shaft 1206.

A third pin 1202 is located above the left side of the second crank frame 1201 and positioned by a fourth end plate 1203. A guide sleeve 1214, a second ball bearing 1215, and a roller 1213 are radially positioned from the inside outward along the third pin 1202. A third pressure cap 1212 and a second sealing ring 1211 are located on either side of the second ball bearing 1215. A lift limit control system 13 is located on the right end of the crank frame 1201 below the transmission side frame 1.

[0116] The induction plate 1302 is processed into a "Z" shape, and the lifting detection switch 1304 and the lifting detection switch 2 1305 are arranged in a horizontal row, which can solve the traditional technical problem of inaccurate detection accuracy caused by the vertical arrangement of two sets of lifting detection switches in a small space.

[0117] The left side of sensor plate 1302 is Q1, and the right side is Q2. In the initial position, lift cylinder 801 is at its minimum travel. Q1 on the left side of sensor plate 1302 is disconnected from lift detection switch 1304, while Q2 on the right side coincides with lift detection switch 2 1305. When lift cylinder 801 is at its maximum travel, Q1 on the left side of sensor plate 1302 coincides with lift detection switch 1304, while Q2 on the right side is disconnected from lift detection switch 2 1305.

[0118] The lateral limit control system 14 includes a bracket 2 1401, a sensor plate 2 1402, a lateral detection switch 1 1403, and a lateral detection switch 2 1404. The bracket 2 1401 is welded and fixed to the top plane of the base 3 902 where the track group 1 9 is located.

The lateral detection switch 1 1403 and the lateral detection switch 2 1404 are respectively fixed to the bracket 2 1401 by bolts.

[0119] The left side of bracket 2 1401 is at point T1, and the right side is at point T2. The distance between points T1 and T2 is λ, and λ = S (S is the lateral travel). In the initial position, the lateral cylinder 701 is at its minimum travel, the second sensor plate 1402 overlaps with the first lateral travel detection switch 1403 at the left point T1, and the second lateral travel detection switch 1404 at the right point T2 is disengaged. When the lateral cylinder 701 is at its maximum travel, the first lateral travel detection switch 1403 at the left point T1 is disengaged, and the second sensor plate 1402 overlaps with the second lateral travel detection switch 1404 at the right point T2.

[0120] 1. Technical principle of waste anti-jamming device:

[0121] The key components of the waste anti-jamming device are the transverse movement mechanism 7, the lifting mechanism 8, the track group 1 9, the track group 2 10 and the crank frame mechanism 12. The transverse movement stroke of the transverse movement mechanism 7 is S, and the lifting stroke of the lifting mechanism 8 is H.

[0122] As an important component of the rolling shearing equipment, the waste anti-jamming device works in conjunction with the upper and lower shear blades, the waste anti-jamming device and the waste collection and transportation device to achieve the following three core functions:

[0123] First, the waste anti-jamming device facilitates both steel plate transport and shearing. The lifting mechanism 8 pushes the crank mechanism 12, which in turn drives the transmission side frame 1 and the fixed side frame 2, completing the lifting and lowering of roller assembly 1 3 and roller assembly 2 11, thus achieving the steel plate transport function.

[0124] When the steel plate passes through the upper and lower shear blades of the rolling shear, the scrap anti-jamming device is raised to the maximum stroke position H by the lifting mechanism 8, and the steel plate is transported to the top of the scrap anti-jamming device. Thereafter, the scrap anti-jamming device is lowered to the initial position by the lifting mechanism 8, and the steel plate is sequentially cut, cut to length, and cut off, thus achieving the shearing function.

[0125] When the steel plates are transported, the waste anti-jamming device is raised; when the steel plates are sheared, the waste anti-jamming device is lowered.

[0126] Second, it quickly removes stuck waste. The waste anti-jamming device, via the transverse mechanism 7, drags the drive side frame 1 and the fixed side frame 2, which in turn drives roller assembly 1 3 and roller assembly 2 11. The entire assembly moves horizontally to the right along track assembly 1 9 and track assembly 2 10, allowing stuck waste to slide smoothly to the waste collection and transportation device, thus achieving waste removal.

[0127] When there is waste material jamming, the waste material anti-jamming device moves with the transverse mechanism 7 to the maximum stroke position T2; when there is no waste material jamming, the waste material anti-jamming device moves with the transverse mechanism 7 to stay at the minimum stroke position T1.

[0128] Third, it facilitates equipment maintenance and lifting. When the equipment is shut down for maintenance, the waste anti-jamming device moves rightward with the transverse mechanism 7 along track group 1 9 and track group 2 10 to the maximum travel position T2, increasing the operating space between the bottom of the rolling shear and the foundation pit, making it easier to repair, maintain, and lift and replace the transverse mechanism 7, lifting mechanism 8, and crank mechanism 12.

[0129] The lifting limit position constraint of the waste material anti-jamming device is realized by the lifting limit control system 13 , and the lateral limit position constraint of the waste material anti-jamming device is realized by the lateral limit control system 14 .

[0130] Working method of waste anti-jamming device:

[0131] In order to further illustrate the technical solution of the present invention, the waste material anti-stuck operation method of the present invention is further described as follows in combination with the embodiment. The specific workflow and operation method include the following steps:

[0132] In the first step, the waste anti-jamming operation method process begins.

[0133] In the second step, the steel plate reaches the entrance area of ​​the rolling shear.

[0134] The steel plate is conveyed by the conveyor rollers in front of the shearing equipment to the shearing entrance area, preparing for subsequent transportation, shearing, and waste removal. At this point, the steel plate has an irregular shape at the head and tail ends along its entire length, requiring the scrap to be removed and the middle section to be cut to length.

[0135] The third step is to check the working conditions of the rolling shear and waste anti-jamming device.

[0136] This step mainly performs two tests: one is whether the lifting cylinder 801 and the transverse cylinder 701 of the waste anti-jamming device are in the minimum stroke position; the other is whether the upper shear blade of the rolling shear is in the open state (the lower shear blade is fixed and the upper shear blade is pressed down to complete the steel plate shearing work).

[0137] The fourth step is to determine whether the lifting cylinder 801 and the transverse cylinder 701 are in the minimum stroke position.

[0138] Before the formal operation starts, the lifting cylinder 801 and the transverse cylinder 701 are in the minimum stroke position to comply with the safety operation specifications.

[0139] If the judgment result is "yes", go directly to step 5.

[0140] If the judgment result is "no", the hydraulic system is driven to retract the piston rods of the lifting cylinder 801 and the transverse cylinder 701, so that the lifting mechanism 8 drops to the minimum stroke position and the transverse mechanism 7 moves horizontally to the left to the minimum stroke position.

[0141] The fifth step is to determine whether the upper shear blade is in the open state.

[0142] Before the formal work starts, the upper shear blade of the rolling shear equipment is in the open state so that the steel plate can pass through the upper and lower shear blades smoothly, preventing the steel plate from damaging the shear blade or affecting the overall quality of the steel plate.

[0143] If the judgment result is "yes", go directly to step 6.

[0144] If the judgment result is "no", the shear blade locking cylinder is driven to lift the upper shear blade so that the upper shear blade remains in the open state.

[0145] Step 6: Lift the waste anti-jamming device.

[0146] The hydraulic system drives the piston rod of the lifting cylinder 801 to gradually extend, pushing the transmission side frame 1 and the fixed side frame 2 through the lifting mechanism 8, and then driving the roller assembly 1 3 and the roller assembly 2 11 to move upward as a whole. After the lifting stroke H, the piston rod of the lifting cylinder 801 reaches the maximum stroke position, completing the lifting work of the waste anti-jamming device.

[0147] Step 7: Preparation before cutting the steel plate.

[0148] 1. Steel plate transportation work: simultaneously drive the transport roller in front of the rolling shearing equipment, roller assembly 13 of the waste anti-jamming device, and roller assembly 211.

[0149] 2. The head of the steel plate passes through the upper and lower shear blades (the same applies to the transportation of the middle and tail of the steel plate).

[0150] 3. Lowering of the waste anti-jamming device: The hydraulic system drives the piston rod of the lifting cylinder 801 to gradually retract, pulling the transmission side frame 1 and the fixed side frame 2 through the lifting mechanism 8, thereby driving the roller assembly 1 3 and the roller assembly 2 11 to move downward as a whole. When the piston rod of the lifting cylinder 801 drops to the minimum stroke position, the lowering work of the waste anti-jamming device is completed.

[0151] The eighth step is cutting the steel plate heads, cutting the lengths, cutting the tails, etc.

[0152] 1. Drive the shear blade locking cylinder to press down the upper shear blade. The upper and lower shear blades work together to complete the shearing of the steel plate. The head waste slides smoothly to the waste collection and transportation device through the gap between the transmission side frame 1, the left side of the fixed side frame 2 and the side wall of the rolling shear base.

[0153] 2. Repeat the steps in step 6.

[0154] 3. Repeat the work of step 7-step 1, and pass the middle of the steel plate through the upper and lower shear blades.

[0155] 4. Repeat the steps from step 7 to step 3.

[0156] 5. Drive the shear blade locking cylinder to press down the upper shear blade, and the upper and lower shear blades work together to complete the cut-to-length work of the steel plate.

[0157] 6. Repeat the work of Step 8 - Steps 2 to 5, and cut the steel plate to length N times until the cutting work is completed.

[0158] 7. Repeat step 6.

[0159] 8. Repeat the work of step 7-step 1, and the tail of the steel plate passes through the upper and lower shear blades

[0160] 9. Repeat steps 7-3.

[0161] 10. Drive the shear blade locking cylinder to press down the upper shear blade. The upper and lower shear blades work together to complete the tail shearing of the steel plate. The tail waste slides smoothly to the waste collection and transportation device through the gap between the transmission side frame 1, the left side of the fixed side frame 2 and the side wall of the rolling shear base.

[0162] 11. Drive the shear blade locking cylinder to lift the upper shear blade and keep it in the open state.

[0163] In the ninth step, the entire steel plate completes all cutting work and waits for the next cutting instruction.

[0164] If there is no cut command, go directly to step 14.

[0165] It should be noted that in the work of Step 8 - Step 1 and Step 10, if the head waste and tail waste are irregular in shape or too large in size, a waste jam will occur, and the head waste and tail waste cannot slide smoothly to the waste collection and transportation device. The following operation process needs to be performed:

[0166] Step 10: After the head and tail cutting work is completed, determine whether there is any waste blocking phenomenon.

[0167] If the judgment result is "yes", go directly to step 11.

[0168] If the judgment result is "no", go to step 14.

[0169] Step 11: The waste blocking device moves to the right.

[0170] The hydraulic system drives the piston rod of the transverse cylinder 701 to gradually extend, and pulls the transmission side frame 1 and the fixed side frame 2 through the transverse mechanism 7, thereby driving the roller assembly 1 3 and the roller assembly 2 11 to move to the right as a whole. After the transverse stroke S, the piston rod of the transverse cylinder 701 reaches the maximum stroke position, completing the rightward transverse movement of the waste anti-jamming device.

[0171] Step 12: Eliminate waste jams.

[0172] After the eleventh step, the gap between the left side of the transmission side frame 1, the fixed side frame 2 and the side wall of the rolling shear base increases by S. Both the head waste and the tail waste can slide smoothly to the waste collection and transportation device, completing the waste cleaning work.

[0173] In the thirteenth step, the waste blocking device moves left and returns to the minimum stroke position.

[0174] The hydraulic system drives the piston rod of the transverse cylinder 701 to gradually retract, and pushes the transmission side frame 1 and the fixed side frame 2 through the transverse mechanism 7, thereby driving the roller assembly 1 3 and the roller assembly 2 11 to move to the left as a whole. When the piston rod of the transverse cylinder 701 reaches the minimum stroke position, the waste anti-jamming device returns to the initial position on the left.

[0175] In the fourteenth step, the work processes of transporting, cutting and eliminating waste jams of the whole steel plate are all completed and enter the next work cycle.

[0176] The present invention is applicable to rolling shearing equipment of medium and thick plate production lines, covering rolling shearing equipment of various specifications such as 3000mm, 3500mm, 3800mm, 4200mm, 4300, 5000mm, and 5600mm. It cooperates to complete the transportation and shearing of steel plates, and promptly cleans up the stuck material heads and tails, and improves work efficiency during equipment maintenance and hoisting.
