Description

Technical Field

[0001] This application relates to the field of steel plate processing, and particularly to a steel plate transverse shearing production line and a steel plate transverse shearing forming process. Background Art

[0002] In the field of metal sheet processing, a steel plate transverse shearing production line usually consists of an uncoiler, a leveling unit, a transverse shearing machine, a conveying device, and a stacking device. With the improvement of industrial automation level, the steel plate transverse shearing production line has played an important role in improving production efficiency, reducing labor costs, and ensuring product quality.

[0003] In the traditional single-line production mode, after a single coil of steel plate is cut by the transverse shearing machine, it is necessary to stop the machine to perform the operations of uncoiling, leveling, and feeding the new coil of steel plate, resulting in the forced interruption of the operation of the transverse shearing machine and subsequent equipment, causing a loss of production efficiency. Especially in the scenario of large-scale continuous production, frequent downtime for material change seriously restricts the improvement of production capacity. In the prior art, there is a solution that uses two independent production lines configured in parallel to solve the above problems. Although this can achieve alternating continuous production, it is necessary to separately equip each production line with core equipment such as a transverse shearing machine, resulting in a significant increase in equipment investment costs. There is also a technology that attempts to set up a sheet metal temporary storage platform in the middle of the production line. However, limited by the risk of self-weight sagging deformation and surface scratching of the sheet metal, it is difficult to achieve effective buffering in practical applications.

[0004] Therefore, how to avoid the cost burden caused by redundant configuration of core equipment while maintaining the advantages of double-line continuous production is a technical bottleneck that needs to be broken through urgently in this field. The present invention is an innovative solution proposed for this key problem. Summary of the Invention

[0005] In order to solve the problem of redundant core equipment in the double-line transverse shearing production line, this application provides a steel plate transverse shearing production line and a steel plate transverse shearing forming process using the same.

[0006] A steel plate transverse shearing production line provided by this application adopts the following technical solution: A steel plate transverse shearing production line includes a first processing line and a second processing line arranged in parallel at intervals. Both the first processing line and the second processing line include, in sequence along the material traveling direction: an uncoiler for unwinding the steel coil; a leveling machine for leveling the unwound steel plate; a conveyor for conveying the transversely cut steel plate; a stacking device for collecting and stacking the steel plates output by the conveyor; and further includes: a first transverse shearing station arranged between the leveling machine and the conveyor in the first processing line, where the leveled steel plate in the first processing line is cut at the first transverse shearing station; a second transverse shearing station arranged between the leveling machine and the conveyor in the second processing line, horizontally aligned with the first transverse shearing station, where the leveled steel plate in the second processing line is cut at the second transverse shearing station; a transverse shearing machine for cutting the leveled steel plate, and the transverse shearing machine can reciprocally slide between the first transverse shearing station and the second transverse shearing station; a driving device arranged below the first processing line and the second processing line for driving the transverse shearing machine to reciprocally slide between the first transverse shearing station and the second transverse shearing station; a fixing device arranged below the transverse shearing machine for fixing the transverse shearing machine at the first transverse shearing station or the second transverse shearing station.

[0007] By adopting the above technical solution, the uncoiler is responsible for the unwinding operation of the steel coil, and the leveling machine levels the unwound steel plate to ensure the quality of subsequent processing. A movable transverse shearing machine is arranged between the first processing line and the second processing line, and the driving device is used to realize the rapid switching of the transverse shearing machine between the first transverse shearing station and the second transverse shearing station. The fixing device is used to accurately position and lock the transverse shearing machine, so as to complete the cutting operation of the steel plate in different processing lines. The conveyor is responsible for conveying the transversely cut steel plate to the stacking device for stacking and collecting, and the whole process is smooth and efficient. This design not only improves the utilization rate of the equipment, but also effectively reduces the downtime caused by switching the processing line, significantly improves the overall efficiency and flexibility of the production line, and can realize the alternate operation of one transverse shearing machine between two processing lines, thus reducing the investment cost of core equipment while ensuring the production efficiency.

[0008] Preferably, a ground rail base groove is provided below the first processing line and the second processing line. Both the first transverse shearing station and the second transverse shearing station are located above the ground rail base groove. A slide rail is provided on the side wall of the ground rail base groove, and the transverse shearing machine is slidably connected to the slide rail. Both the fixing device and the driving device are arranged in the ground rail base groove.

[0009] By adopting the above technical solution, the setting of the ground rail base groove provides a stable track environment for the sliding of the transverse shearing machine, ensuring that the reciprocating sliding of the transverse shearing machine between the first transverse shearing station and the second transverse shearing station is more stable and accurate. The setting of the slide rail further reduces the friction resistance when the transverse shearing machine slides, and improves the sliding efficiency. At the same time, the fixing device and the driving device are integrated in the ground rail base groove, which effectively reduces the space occupied by the equipment and improves the compactness and aesthetics of the overall production line.

[0010] Preferably, the fixing device includes a locking block, which is slidably arranged on the bottom of the transverse shearing machine, and a locking groove cooperating with the locking block is arranged on the bottom surface of the ground rail base groove. There are several locking grooves and they are respectively arranged corresponding to the first transverse shearing station and the second transverse shearing station. A locking spring for driving the locking block to slide toward the locking groove is provided at the bottom of the transverse shearing machine, and an unlocking mechanism for pushing the locking block out of the locking groove is provided in the locking groove.

[0011] By adopting the above technical solution, the shearing machine can flexibly switch between the first shearing station and the second shearing station and fix them firmly. When the shearing machine moves to the target shearing station, the locking block automatically slides into the locking groove corresponding to the station under the action of the locking spring, so as to realize the rapid locking of the shearing machine and ensure the stability of the shearing operation. When the shearing station needs to be replaced, the unlocking mechanism moves the locking block out of the locking groove, so that the shearing machine can be quickly unlocked, which is convenient for the driving device to pull the shearing machine to move to another shearing station, thereby improving the operating efficiency and flexibility of the production line.

[0012] Preferably, the unlocking mechanism includes a lifting frame slidably arranged in the lock slot, a cam rotatably connected in the lock slot and abutting against the lifting frame, the cam is located below the lifting frame, when the cam rotates to the farthest point and abuts against the lifting frame, the lifting frame is lifted up and pushes the locking block out of the lock slot.

[0013] By adopting the above technical solution, when the cross-cutting shearing machine needs to be unlocked, the cam is first rotated. As the cam rotates, its farthest point gradually approaches and finally abuts against the lifting frame. At this time, the lifting frame is pushed up by the cam, and then the locking block located in the locking groove is pushed out of the locking groove. Since the locking block is separated from the locking groove, the cross-cutting machine is no longer subject to fixed restrictions, so that it can slide and switch smoothly between the first cross-cutting station and the second cross-cutting station. This design not only realizes the rapid unlocking of the cross-cutting machine, but also ensures the efficient operation of the entire production line, and improves the flexibility and automation of the cross-cutting processing of steel plates.

[0014] Preferably, the cams in all the lock grooves are connected by the same camshaft, both ends of the camshaft are fixedly connected with driven gears, and the side surfaces of the ground rail base groove are slidably connected with racks meshing with the driven gears.

[0015] By adopting the above technical solution, synchronous control of the cams in multiple lock grooves can be achieved. Specifically, by connecting all the cams to the same camshaft, the movement consistency of each cam is ensured, thereby improving the reliability of the cross-cutting machine when switching between different cross-cutting stations; at the same time, by using the cooperation of the driven gear and the rack, the camshaft can be conveniently rotated by the sliding of the rack, and then the cam is used to lift the lifting frame to complete the unlocking action. This design simplifies the control structure, improves the operation efficiency, and ensures the stability of the fixing and unlocking processes of the cross-cutting machine.

[0016] Preferably, the driving device includes bases fixedly arranged at both ends of the ground rail base groove, a wire wheel rotatably connected to the bases, and the wire wheel is connected to the cross-cutting machine through a traction cable.

[0017] By adopting the above technical solution, the bases are fixedly arranged at both ends of the ground rail base groove, providing stable support for the entire driving device. The wire wheel is rotatably connected to the bases and can rotate flexibly. At the same time, it is connected to the cross-cutting machine through a traction cable, achieving precise traction of the cross-cutting machine. This design enables the cross-cutting machine to move smoothly and efficiently between the first cross-cutting station and the second cross-cutting station, ensuring the continuity and stability of the steel plate cross-cutting production line.

[0018] Preferably, a control device is provided between the driving device and the fixing device. The control device is used to first drive the driven gear to rotate to release the locking between the lock block and the lock groove, and then drive the wire wheel to rotate to traction the cross-cutting machine to slide to the first cross-cutting station or the second cross-cutting station.

[0019] By adopting the above technical solution, the movement and locking operations of the cross-cutting machine achieve highly integrated control. Specifically, the control device can coordinate the actions of the driven gear and the wire wheel in an orderly manner, ensuring that when the cross-cutting machine switches stations, the unlocking operation is first completed to avoid mechanical interference, and then the cross-cutting machine is accurately tractioned to the target position, thereby effectively improving the automation level and operation efficiency of the production line. In addition, this control logic optimizes the operation process of the equipment, reduces the possibility of human intervention, and further improves the stability and reliability of the system.

[0020] Preferably, the control device includes: a fixed frame arranged in the ground rail base groove; an operating rod rotatably connected to the fixed frame; a first bevel gear fixed to the end of the operating rod; a second bevel gear fixed to the rotating shaft of the wire wheel and meshing with the first bevel gear; a third bevel gear rotatably connected to the fixed frame and meshing with the second bevel gear; a screw threadedly connected to the central hole of the third bevel gear and fixed to the rack; a contact spring arranged at the bottom of the rack to keep the screw in contact with the third bevel gear all the time; a clutch mechanism arranged between the rotating shaft of the wire wheel and the second bevel gear to control power transmission.

[0021] By adopting the above technical solution, the operator can realize the full-process control of unlocking, moving and relocking the cross-cutting machine through a simple operation of rotating the operating rod. The design of the clutch mechanism enables flexible control of power transmission, integrates multiple functions into a single operating device, significantly simplifies the operation process, and reduces the operation difficulty. At the same time, by using bevel gear transmission and screw structure, the stability and accuracy of power transmission are ensured, effectively avoiding accidental deviation or inaccurate positioning of the cross-cutting machine during movement.

[0022] Preferably, the clutch mechanism includes a control rod slidably disposed in the rotating shaft of the wire wheel. One end of the control rod extends out of the second bevel gear, and a plurality of blocks are fixedly connected to the other end of the control rod. The end of the block extends out of the rotating shaft of the wire wheel. A collar is fixedly connected to the second bevel gear, and the collar is sleeved outside the rotating shaft of the wire wheel. A bayonet matching with the block is provided on the collar, and a clamping spring for driving the block to slide towards the bayonet is provided in the rotating shaft of the wire wheel.

[0023] By adopting the above technical solution, flexible control of power transmission between the wire wheel and the second bevel gear can be realized. Specifically, when power transmission is required, the block cooperates with the bayonet on the collar under the action of the clamping spring to ensure stable power transmission; when power transmission needs to be disconnected, the block can be driven by the control rod to disengage from the bayonet, thereby quickly cutting off the power transmission path. This design not only improves the operation efficiency of the cross-cutting machine when switching between different workstations, but also effectively reduces the energy loss and mechanical wear caused by unnecessary transmission.

[0024] A steel plate cross-cutting and forming process applying the above steel plate cross-cutting production line includes the following steps: Step S1: Synchronously start the uncoilers of the first processing line and the second processing line to unwind the steel coils respectively; Step S2: Feed the unwound steel plates into the levelers of the corresponding processing lines for leveling; Step S3: When the steel plate on the first processing line reaches the first cross-cutting station, move the cross-cutting machine along the ground rail base groove to the first cross-cutting station through the driving device and lock it by the fixing device; Step S4: The cross-cutting machine cross-cuts the steel plate in the first processing line, and the cut steel plates are sent to the stacking device through the conveyor for stacking. At the same time, the steel plate on the second processing line pauses in front of the second cross-cutting station after leveling; Step S5: When the steel coil in the first processing line is processed, the control device releases the fixing of the cross-cutting machine, and the driving device moves the cross-cutting machine to the second cross-cutting station and locks it; Step S6: The cross-cutting machine cross-cuts the steel plate on the second processing line, and the cut steel plates are sent to the stacking device through the conveyor for stacking. At the same time, a steel coil replenishment operation is performed on the uncoiler in the first processing line; Step S7: Repeat Steps S3-S6, and through the alternating operation of the cross-cutting machine between the first cross-cutting station and the second cross-cutting station, continuous production of the first processing line and the second processing line is realized.

[0025] By adopting the above technical solutions, the horizontal shearing and forming process of the steel plate can significantly improve the operation efficiency and flexibility of the production line. Specifically, by alternately using the same horizontal shearing machine between two processing lines and combining precise driving and fixing devices, the maximum utilization of resources is achieved. While the horizontal cutting operation is carried out on the first processing line, the second processing line can be prepared in advance, reducing the idle time of the equipment. In addition, when the steel coil on one processing line is exhausted, the horizontal shearing machine can quickly switch to the other processing line to continue the operation, ensuring the continuity of the production line and providing sufficient time window for the steel coil replenishment operation. This alternating operation mode not only reduces the equipment investment cost but also effectively improves the stability of the overall production rhythm.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the reciprocating sliding and precise positioning of the horizontal shearing machine between two processing lines, the continuous horizontal cutting operation of the steel plate in the double-line production mode is realized, effectively avoiding the downtime waiting caused by material change, and significantly improving the overall efficiency of the production line; 2. The design of a single horizontal shearing machine serving two processing lines simultaneously avoids the repeated configuration of equipment while meeting the alternating production requirements, greatly reducing the equipment procurement and maintenance costs; 3. The coordinated cooperation of the driving device and the fixing device ensures the stability and reliability of the horizontal shearing machine during the process of switching workstations, further optimizing the cutting accuracy and production rhythm.

[0034] The following further elaborates on this application in conjunction with the attached Figures 1-6 drawings.

[0035] Embodiment 1 An embodiment of this application discloses a steel plate transverse cutting production line.

It further includes a first transverse cutting station 15, a second transverse cutting station 16, a transverse cutting machine 2, a driving device 5, and a fixing device 4. Among them, the first transverse cutting station 15 is arranged between the leveler 12 and the conveyor 13 in the first processing line 1a, the second transverse cutting station 16 is arranged between the leveler 12 and the conveyor 13 in the second processing line 1b, the transverse cutting machine 2 can reciprocally slide between the first transverse cutting station 15 and the second transverse cutting station 16, the driving device 5 is arranged below the first processing line 1a and the second processing line 1b to drive the transverse cutting machine 2 to reciprocally slide, and the fixing device 4 is arranged below the transverse cutting machine 2 to fix the transverse cutting machine 2 at the corresponding station, achieving the effect of avoiding the cost burden caused by redundant configuration of core equipment while maintaining the advantages of continuous production on two lines.

[0036] Refer to Figure 2 and Figure 3, the cross-cutting machine 2 includes a frame 21 and a blade 22, thus realizing the cross-cutting function of the steel plate. On the ground below the first processing line 1a and the second processing line 1b, a ground rail base groove 3 is provided. The ground rail base groove 3 is a sunken groove, and the ground rail base groove 3 is arranged perpendicular to the conveying direction of the first processing line 1a. Both the first cross-cutting station 15 and the second cross-cutting station 16 are located above the ground rail base groove 3. On the side wall of the ground rail base groove 3, a slide rail is fixedly connected, and pulleys matching the slide rail are provided at the bottom of the cross-cutting machine 2. Through the cooperation of the slide rail and the pulleys, the cross-cutting machine 2 can slide in the ground rail base groove 3. In addition, to prevent sundries from falling into the ground rail base groove 3 during the production process, bellows cover plates 23 are connected to both sides of the cross-cutting machine 2. The bellows cover plates 23 can cover the opening of the ground rail base groove 3. One end of the bellows cover plate 23 is fixed to the ground rail base groove 3, and the other end is fixed to the side of the cross-cutting machine 2. Of course, other existing dust-proof structures such as chain plates can also be used for shielding to improve the safety during the production process.

[0037] To facilitate the replacement and maintenance of the blade 22, a first maintenance station 17 is provided on one side of the first cross-cutting station 15 away from the second cross-cutting station 16, and a second maintenance station 18 is provided on one side of the second cross-cutting station 16 away from the first cross-cutting station 15. Both the first maintenance station 17 and the second maintenance station 18 are located above the ground rail base groove 3. The cross-cutting machine 2 can reciprocally slide and be fixed between the first cross-cutting station 15, the second cross-cutting station 16, the first maintenance station 17, and the second maintenance station 18.

[0038] To reduce the equipment volume and floor area, the fixing device 4 and the driving device 5 are also arranged in the ground rail base groove 3. The fixing device 4 includes a locking block 41 and a locking groove 31. The locking block 41 is slidably arranged along the vertical direction at the bottom of the cross-cutting machine 2. A locking spring 42 is fixedly connected to the bottom of the cross-cutting machine 2. One end of the locking spring 42 away from the cross-cutting machine 2 is fixed to the locking block 41. The locking spring 42 is vertically arranged, and the locking spring 42 always drives the locking block 41 to slide towards the locking groove 31. The locking groove 31 is arranged on the bottom surface of the ground rail base groove 3. The size of the locking block 41 matches that of the locking groove 31. There are four locking grooves 31, which are respectively arranged corresponding to the first cross-cutting station 15, the second cross-cutting station 16, the first maintenance station 17, and the second maintenance station 18.

[0039] Refer to Figure 3 and Figure 4, To facilitate the unlocking of the lock block 41 from the lock groove 31, the fixing device 4 further includes an unlocking mechanism. The unlocking mechanism includes a lifting frame 43 slidably disposed in the lock groove 31. A sliding rod 431 is fixedly connected to the lifting frame 43, and a sleeve cooperating with the sliding rod 431 is fixedly connected to the bottom surface of the lock groove 31. A cam 44 in rotational connection with the lifting frame 43 is disposed in the lock groove 31. The cam 44 is located below the lifting frame 43. Under the action of its own gravity and the pressure of the lock block 41, the lifting frame 43 is always in contact with the cam 44. When the cam 44 rotates to the farthest point and contacts the lifting frame 43, the lifting frame 43 is jacked up and the lock block 41 is pushed out of the lock groove 31. The cams 44 in all the lock grooves 31 are connected by the same camshaft 45. Driven gears 451 are fixedly connected to both ends of the camshaft 45. A rack 46 meshing with the driven gears 451 is slidably connected to the side of the ground rail base groove 3 and the rack 46 is driven by the control device 6. To facilitate installation and drive, between the driven gear 451 and the rack 46, power is transmitted through the meshing of a number of intermediate gears in sequence. In addition, to reduce the friction between the cam 44 and the lifting frame 43, a contact wheel 432 in rotational connection with the outer peripheral surface of the cam 44 is disposed at the bottom of the lifting frame 43, and the rotation axis of the contact wheel 432 is parallel to the rotation axis of the cam 44.

[0040] To reduce the friction force on the bottom surface of the lock block 41 during the sliding of the horizontal cutting machine 2, a guide wheel 7 is rotatably connected to the top of the lifting frame 43. On the bottom surface of the ground rail base groove 3, a number of guide wheels 7 are also arranged in an array along the length direction of the ground rail base groove 3. When the lifting frame 43 slides upward to the highest point, the guide wheel 7 on the lifting frame 43 is flush with the guide wheel 7 in the ground rail base groove 3, and the rotation direction of the guide wheel 7 is tangentially arranged with the sliding direction of the horizontal cutting machine 2.

[0041] To facilitate the sliding of the horizontal cutting machine 2 in the unlocked state, the driving device 5 includes bases 51 fixedly arranged at both ends of the ground rail base groove 3. A wire wheel 52 is rotatably connected to the base 51. The wire wheel 52 is connected to the horizontal cutting machine 2 through a traction cable 53. One end of the traction cable 53 is fixed to the wire wheel 52 and the other end is fixed to the horizontal cutting machine 2. By respectively rotating the wire wheels 52 at both ends of the ground rail base groove 3, the horizontal cutting machine 2 can be pulled to slide towards the corresponding wire wheel 52, thereby realizing the drive of the wire wheel 52.

[0042] In addition, referring to Figure 5 and Figure 6, a control device 6 is provided between the driving device 5 and the fixing device 4. The control device 6 is used to first drive the driven gear 451 to rotate to release the locking between the locking block 41 and the locking groove 31, and then drive the wire wheel 52 to rotate to pull the horizontal cutting machine 2 to slide to the first horizontal cutting station 15 or the second horizontal cutting station 16. The control device 6 can orderly coordinate the actions of the driven gear 451 and the wire wheel 52, ensuring that when the horizontal cutting machine 2 switches stations, the unlocking operation is first completed to avoid mechanical interference, and then the horizontal cutting machine 2 is accurately pulled to the target position, thereby effectively improving the automation level and operation efficiency of the production line.

[0043] Control devices 6 are provided at both ends of the ground rail base groove 3. The control device 6 includes a fixing frame 61, an operating rod 62, a bevel gear set, and a screw rod 66. The fixing frame 61 is fixedly arranged in the ground rail base groove 3. The operating rod 62 is rotatably connected to the fixing frame 61. The operating rod 62 is vertically arranged. One end of the operating rod 62 extends above the ground and is connected with a handwheel 621 for the convenience of the operator to rotate. The first bevel gear 63 is fixed to the end of the operating rod 62. The rotating shaft of the wire wheel 52 is rotatably connected to the fixing frame 61. The rotating shaft of the wire wheel 52 is perpendicular to the operating rod 62. The second bevel gear 64 is sleeved on the rotating shaft of the wire wheel 52 and meshes with the first bevel gear 63. The third bevel gear 65 is rotatably connected to the fixing frame 61 and meshes with the second bevel gear 64. The rack 46 is vertically arranged and is slidably connected to the fixing frame 61. A slider slidably connected to the fixing frame 61 is provided on the rack 46. A screw rod 66 is fixedly connected to the top of the rack 46. The screw rod 66 is coaxially arranged with the operating rod 62. The screw rod 66 is threadedly connected to the central hole of the third bevel gear 65. A contact spring 461 is fixedly connected to the bottom of the rack 46. The contact spring 461 is vertically arranged. One end of the contact spring 461 away from the rack 46 is fixedly connected to the fixing frame 61. The contact spring 461 drives the rack 46 to slide upward so that the screw rod 66 is always in contact with the third bevel gear 65. A clutch mechanism 67 is arranged between the rotating shaft of the wire wheel 52 and the second bevel gear 64 to control power transmission. The clutch mechanism 67 controls the connection and separation between the rotating shaft of the wire wheel 52 and the second bevel gear 64 according to the extension of the screw rod 66 on the third bevel gear 65.

[0044] The clutch mechanism 67 includes a control rod 671 slidably disposed within the rotating shaft of the line wheel 52. A counterbore for the control rod 671 to slide is provided at the end of the rotating shaft of the line wheel 52. The control rod 671 is coaxially arranged with the rotating shaft of the line wheel 52 and slides along the length direction of the rotating shaft of the line wheel 52. One end of the control rod 671 extends out of the second bevel gear 64 and can extend above the screw rod 66. A plurality of clamping blocks 6711 are fixedly connected to the other end of the control rod 671. The ends of the clamping blocks 6711 extend out of the rotating shaft of the line wheel 52. A long strip-shaped through groove for the clamping blocks 6711 to extend out is provided on the rotating shaft of the line wheel 52. In this embodiment, there are 4 clamping blocks 6711. A collar 68 is fixedly connected to the second bevel gear 64. The collar 68 is sleeved outside the rotating shaft of the line wheel 52. A bayonet 681 for cooperating with the clamping blocks 6711 is provided on the collar 68. A clamping spring 69 for driving the clamping blocks 6711 to slide towards the bayonet 681 is arranged within the rotating shaft of the line wheel 52. The clamping spring 69 is arranged along the length direction of the control rod 671. One end of the clamping spring 69 is fixed to the control rod 671, and the other end is fixed to the rotating shaft of the line wheel 52.

[0045] To facilitate pushing the control rod 671 into the rotating shaft of the line wheel 52, guiding inclined surfaces 8 which are conically arranged are provided at the tops of both the control rod 671 and the screw rod 66.

[0046] In the initial state, the top of the screw rod 66 extends out of the third bevel gear 65, and the top of the screw rod 66 abuts against the end of the control rod 671. At this time, the control rod 671 is in a compressed state, the clamping blocks 6711 are separated from the bayonet 681, and when the second bevel gear 64 rotates, the rotating shaft of the line wheel 52 will not be driven to rotate together; when it is necessary to move the cross-cutting machine 2, rotate the operating rod 62, and the first bevel gear 63, the second bevel gear 64, and the third bevel gear 65 are driven to rotate in sequence. At this time, the screw rod 66 slides downward, driving the rack 46 to slide downward, driving the driven gear 451 to rotate, and further driving the cam 44 to rotate. The lifting frame 43 slides upward, pushing the locking block 41 out of the locking groove 31; When the end of the screw rod 66 slides to be disengaged from the control rod 671, at this time, the thread on the screw rod 66 completely moves outside the third bevel gear 65. After the third bevel gear 65 continues to rotate, the screw rod 66 will not move downward either, the rack 46 remains at the current height, the control rod 671 resets under the action of the clamping spring 69, and the clamping blocks 6711 are snapped into the bayonet 681. At this time, continue to rotate the operating rod 62, and the second bevel gear 64 can drive the line wheel 52 to rotate, thereby pulling the cross-cutting machine 2 to move towards the operating rod 62 at the corresponding end; After the horizontal cutting machine 2 moves into place, reverse-rotate the operating lever 62, and the screw 66 is screwed back into the second bevel gear 64. At this time, although the wire wheel 52 will rotate in the reverse direction, it will not pull the horizontal cutting machine 2 to move. When the screw 66 rises to the position where it abuts against the control lever 671, the control lever 671 resets, the latch 6711 separates from the bayonet 681. At the same time, the rack 46 slides upward driven by the screw 66, all the cams 44 rotate in the reverse direction, the lifting frame 43 slides downward, and the locking block 41 extends from the horizontal cutting machine 2 into the corresponding locking groove 31 under the drive of the locking spring 42 to complete the locking of the horizontal cutting machine 2; When it is desired to operate the horizontal cutting machine 2 to slide in the reverse direction, follow the above steps and rotate the operating lever 62 at the other end of the ground rail base groove 3.

At the same time, the steel plate on the second processing line 1b pauses in front of the second horizontal cutting station 16 after being leveled; Step S5, when the steel coil on the first processing line 1a is processed, the control device 6 releases the fixation of the horizontal cutting machine 2, and the driving device 5 moves the horizontal cutting machine 2 to the second horizontal cutting station 16 and locks it; S6, the horizontal cutting machine 2 horizontally cuts the steel plate on the second processing line 1b, and the cut steel plate is sent to the stacking device 14 through the conveyor 13 for stacking. At the same time, a steel coil replenishment operation is performed on the uncoiler 11 in the first processing line 1a; S7. Repeat steps S3 - S6.
