Description

Technical Field

[0001] The 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 material anti-stuck device and a working method for a rolling shear. Background Art

[0002] As an important component of the rolling shear equipment, the waste anti-jamming device is located at the bottom of the rolling shear. Its main function is to complete the shearing processes such as head cutting, sizing and tail cutting of steel plates through the lifting roller and the upper and lower shear blades of the rolling shear. At the same time, it is convenient for the head cutting waste and the tail cutting waste to slide smoothly into the waste collection and transportation device below it, thus providing guarantee 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, the steel plate needs to be cut to length by a rolling shear and a waste anti-stuck device to complete the shearing processes such as cutting the head, cutting the length, and cutting the tail, so as to comprehensively improve the quality of the head and tail of the steel plate. This area involves two tasks: steel plate transportation and steel plate shearing: when the steel plate is transported, the lifting roller is lifted, 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 descends, 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 through the roller assembly of the lifting roller; after the steel plate is cut to length and cut to the tail, the waste passes through the gap between the lifting roller frame and the rolling shear base, slides to the waste collection and transportation device, and is transferred to the waste pit. This reciprocating cycle continues until all the shearing of the steel plate 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-stuck device poses a severe test. The second waste anti-stuck 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, multiple roller assemblies of the lifting roller adopt a centralized transmission type, which takes up a large 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, and 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 land 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 waste anti-stuck device for rolling shears, which can solve the risks and technical difficulties existing in the prior art, such as easy equipment failure, difficult cleaning of stuck waste, and difficulty in maintenance and lifting, through equipment structure innovation and process optimization.

[0034] S1. The steel plate arrives at the entrance of the rolling shear: The steel plate is transported to the entrance of the rolling shear through the transport roller in front of the rolling shear equipment, and is prepared for the subsequent transportation, shearing and waste cleaning of the steel plate. At this time, the head and tail ends of the steel plate in the full length direction are irregular in shape, 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 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 lateral movement 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, and the lifting mechanism pushes the transmission side frame and the fixed side frame to drive 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 work of the waste anti-jamming device;

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

[0040] a. Steel plate transportation work: drive the transport roller in front of the rolling shearing equipment, roller assembly 1 and roller assembly 2 of the waste anti-stuck device at the same time;

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

[0042] c. Dropping of the waste anti-jamming device: The hydraulic system drives the piston rod of the lifting cylinder to gradually retract, and the lifting mechanism pulls the transmission side frame and the fixed side frame to drive the roller assembly 1 and the roller assembly 2 to move downward as a whole. When the piston rod of the lifting cylinder drops to the minimum stroke position, the dropping of the waste anti-jamming device is completed;

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

[0044] a. The head of the steel plate passes through the upper shear blade and the lower shear blade, and the shear blade locking cylinder is driven to press the upper shear blade down. The upper shear blade and the lower shear blade 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, and the middle part 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 N times of fixed-length shearing of the steel plate until the fixed-length shearing work is completed;

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

[0048] S7, the whole steel plate completes all shearing work 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 waste blocking:

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

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

[0054] S02, rightward movement of the waste anti-jamming device: the hydraulic system drives the piston rod of the lateral movement cylinder to gradually extend, and the lateral movement mechanism pulls the transmission side frame and the fixed side frame, thereby driving the roller assembly 1 and the roller assembly 2 to move rightward 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 waste and the tail waste can slide smoothly to the waste collection and transportation device, completing the waste cleaning work;

[0056] S04, the waste material blocking device moves left and returns to the minimum stroke position: the hydraulic system drives the piston rod of the lateral movement cylinder to gradually retract, and the lateral movement mechanism pushes the transmission side frame and the fixed side frame to drive the roller assembly 1 and the roller assembly 2 to move to the left as a whole. When the piston rod of the lateral movement cylinder reaches the minimum stroke position, the waste material blocking device returns to the 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.

DETAILED DESCRIPTION

[0079] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments 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.

[0080] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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 by no means 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 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 exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates 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 described in these embodiments, the numerical expressions and numerical values ​​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 technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0083] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the 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 contours 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 here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". 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. If not 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 an important part of the rolling shear equipment, the waste anti-jamming device mainly realizes three core functions: the first is to cooperate in the transportation and shearing of steel plates, the second is to facilitate the smooth sliding of waste to the waste collection and transportation device, and the third is to facilitate equipment maintenance and hoisting. This technology completes the transportation, shearing and sliding of steel plates through the synergy of the upper and lower shear blades of the rolling shear, the waste anti-jamming device and the waste collection and transportation device, realizing the three core functions of the waste anti-jamming device.

[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, transverse movement limit control system 14.

[0089] The waste anti-stuck device pushes the crank frame mechanism 12 through the lifting mechanism 8 and then drives the transmission side frame 1 and the fixed side frame 2 to complete the lifting and lowering of the roller assembly 1 3 and the roller assembly 2 11, realizing the steel plate transportation function, and its lifting stroke is H. When the steel plate passes through the upper and lower shear blades of the rolling shearing equipment, the steel plate completes the head cutting, length cutting, tail cutting and other tasks in sequence to realize 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 moves horizontally along the track group 1 9 and the track group 2 10 to realize the waste removal function. The transverse travel is S.

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

[0092] The transmission side frame 1 and the fixed side frame 2 are both welded structures. Four groups of cross beams 4 are arranged between the transmission side frame 1 and the fixed side frame 2. The cross beams 4 are welded structures, and their two ends are respectively fastened to the side walls of the transmission side frame 1 and the fixed side frame 2 by bolts. The transmission side frame 1, the fixed side frame 2 and the cross beams 4 together constitute the supporting components of the waste anti-stuck device, which are used to bear the vertical load and impact load of the steel plate, the roller assembly 1 3, the cover plate 5, the side bracket 6, the roller assembly 2 11 and other components.

When lifting, the steel plate contacts the top of roller assembly 1 3 and roller assembly 2 11, so that the steel plate can be transported; when descending, 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 shearing device are cooperated to realize steel plate shearing.

[0109] Track group 2 10 is located below the movable side frame 1. Except for the second rail 1001 and the groove roller 1011, 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 group 1 9 and track group 2 10 serve as transverse channels for the fixed side frame 2 and the transmission side frame 1, and cooperate to complete the transverse movement of the waste anti-jamming device, which can increase the gap between the left side of the transmission side frame 1 and the fixed side frame 2 and the side wall of the rolling shear base, and quickly complete the waste cleaning.

The main reason is that the waste anti-jamming device of the present technology has a transverse movement function, and its transverse movement stroke is S. The design of this structural type takes into account that when the waste anti-jamming device moves to the right to the maximum stroke position T2, it avoids hitting the adjacent equipment on the outlet side of the waste anti-jamming device.

[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 the induction plate 1302 is the Q1 point, and the right side is the Q2 point; in the initial position, the lifting cylinder 801 is at the minimum stroke position, the Q1 point on the left side of the induction plate 1302 is disconnected from the lifting detection switch 1304, and the Q2 point on the right side coincides with the lifting detection switch 2 1305.

[0120] 1. Technical principle of waste anti-stuck 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 part of the rolling shearing equipment, the waste anti-jamming device works together 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-stuck device pushes the crank frame mechanism 12 through the lifting mechanism 8, and then drives the transmission side frame 1 and the fixed side frame 2 to complete the lifting and lowering of the roller assembly 1 3 and the roller assembly 2 11, so as to realize the steel plate transportation function.

[0124] When the steel plate passes through the upper and lower shear blades of the rolling shearing device, the waste anti-jamming device is lifted to the maximum stroke position H by the lifting mechanism 8, and the steel plate is transported to the top of the waste anti-jamming device. Thereafter, the waste 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 to the tail, thus realizing the shearing function.

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

[0126] Second, quickly remove the stuck waste. The waste anti-jamming device drags the transmission side frame 1 and the fixed side frame 2 through the transverse movement mechanism 7, and then drives the roller assembly 1 3 and the roller assembly 2 11, and the whole moves horizontally to the right along the track group 1 9 and the track group 2 10, so that the stuck waste can slide smoothly to the waste collection and transportation device, realizing the waste removal function.

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

[0128] Third, it is convenient for equipment maintenance and hoisting. When the equipment is shut down for maintenance, the waste anti-stuck device moves to the right along the track group 1 9 and the track group 2 10 with the transverse movement mechanism 7 to the maximum travel position T2, which increases the operating space between the bottom of the rolling shear and the foundation pit, and is convenient for the maintenance and hoisting replacement of the transverse movement mechanism 7, the lifting mechanism 8, and the crank frame 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 movement limit position constraint of the waste material anti-jamming device is realized by the lateral movement 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 embodiments. The specific workflow and operation method include the following steps:

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

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

[0134] The steel plate is transported to the entrance area of ​​the rolling shear through the conveyor roller in front of the rolling shear equipment, preparing for the subsequent steel plate transportation, shearing and waste cleaning. At this time, the head and tail ends of the steel plate in the full length direction are irregular in shape, 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 of the steel plate is completed.

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

[0146] The hydraulic system drives the piston rod of the lifting cylinder 801 to gradually extend, and pushes 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 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 steel plates.

[0148] 1. Steel plate transportation work: simultaneously drive the transport roller in front of the rolling shearing equipment, roller assembly 1-3 and roller assembly 2-11 of the waste anti-stuck device.

[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. The waste anti-jamming device descends: the hydraulic system drives the piston rod of the lifting cylinder 801 to gradually retract, and pulls 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 descends 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, lengths, and tails.

[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 head 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 the middle part of the steel plate passes 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 shear blade and the lower shear blade work together to complete the cut-to-length shearing 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 to length 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 the steps from step 7 to step 3.

[0161] 10. Drive the shear blade locking cylinder to press down the upper shear blade. The upper shear blade and the lower shear blade 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 so that the upper shear blade remains 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 cutting instruction, go directly to step 14.

[0165] It should be noted that in the eighth step - step 1 and step 10, if the head waste and tail waste are irregular in shape or too large in size, there will be a waste jam failure, and the head waste and tail waste cannot slide smoothly to the waste collection and transportation device. The following operation process is required:

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

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

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

[0171] Step 12: Eliminate waste jams.

[0172] After the eleventh step is completed, 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, and both the head waste and the tail waste can slide smoothly to the waste collection and transportation device to complete 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 and shearing equipment of medium and thick plate production lines, covering rolling and shearing equipment of various specifications such as 3000mm, 3500mm, 3800mm, 4200mm, 4300, 5000mm, 5600mm, etc., and can cooperate to complete the transportation and shearing of steel plates, and clean up the stuck material heads and tails in time, and improve the work efficiency during equipment maintenance and hoisting.
