Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel plate processing, in particular to a steel plate cross-cutting production line and a steel plate cross-cutting forming process. BACKGROUND

[0002] In the field of metal plate processing, a steel plate cross-cutting production line is usually composed of an uncoiler, a flattener unit, a cross-cutting machine, a conveying device and a material receiving device. With the improvement of industrial automation level, the steel plate cross-cutting production line plays an important role in improving production efficiency, reducing labor costs and ensuring product quality.

[0003] In the traditional single-line production mode, when a single roll of steel plate is cut by the cross-cutting machine, the uncoiling, flattening and feeding operations of a new roll of steel plate need to be stopped, which forces the cross-cutting machine and subsequent equipment to be interrupted, resulting in a loss of production efficiency. Especially in the context of large-scale continuous production, frequent stoppage for material replacement seriously restricts the improvement of production capacity. In the prior art, a scheme of configuring two independent production lines in parallel is used to solve the above problem, which can realize alternating continuous production, but requires each production line to be equipped with core equipment such as a cross-cutting machine, resulting in a significant increase in equipment investment costs. Another technology attempts to set a plate temporary storage platform in the middle of the production line, but due to the risk of plate sagging deformation and surface scratching under its own weight, it is difficult to achieve effective caching in actual application.

[0004] Therefore, how to maintain the advantages of double-line continuous production while avoiding the cost burden caused by redundant configuration of core equipment is a technical bottleneck that needs to be broken through in the field. The present application is an innovative solution to this key problem. SUMMARY

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

[0006] The steel plate transverse cutting production line provided by the application adopts the technical scheme as follows: a steel plate transverse cutting production line, comprising a first processing line and a second processing line arranged in parallel and at intervals, the first processing line and the second processing line each comprising, in sequence along the material advancing direction: an uncoiler for unwinding a steel coil; a leveler for leveling the steel plate after unwinding; a conveyor for conveying the steel plate after transverse cutting; a material collecting device for collecting the steel plate stacked and output by the conveyor; further comprising: a first transverse cutting station arranged between the leveler and the conveyor in the first processing line, the steel plate after leveling in the first processing line being subjected to cutting operation in the first transverse cutting station; a second transverse cutting station arranged between the leveler and the conveyor in the second processing line, the second transverse cutting station being arranged transversely aligned with the first transverse cutting station, the steel plate after leveling in the second processing line being subjected to cutting operation in the second transverse cutting station; a transverse cutting machine for cutting the steel plate after leveling, the transverse cutting machine being capable of reciprocating sliding between the first transverse cutting station and the second transverse cutting station; a driving device arranged below the first processing line and the second processing line for driving the transverse cutting machine to reciprocate slide between the first transverse cutting station and the second transverse cutting station; a fixing device arranged below the transverse cutting machine for fixing the transverse cutting machine at the first transverse cutting station or the second transverse cutting station.

[0007] By adopting the above technical scheme, the uncoiler is responsible for the unwinding operation of the steel coil, and the leveler is used for leveling the steel plate after unwinding to ensure the quality of subsequent processing. The movable transverse cutting 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 cutting machine between the first transverse cutting station and the second transverse cutting station, and the fixing device is used to accurately position and lock the transverse cutting machine, so as to complete the cutting operation of the steel plate in different processing lines. The conveyor is responsible for conveying the steel plate after transverse cutting to the material collecting device for stacking and collecting, and the whole process is smooth and efficient. The 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 realizes the alternating operation of one transverse cutting machine between two processing lines, thereby ensuring the production efficiency while reducing the investment cost of the core equipment.

[0008] Preferably, a ground rail base groove is arranged below the first processing line and the second processing line, the first transverse cutting station and the second transverse cutting station are located above the ground rail base groove, a slide rail is arranged on the side wall of the ground rail base groove, the transverse cutting machine is in sliding connection with the slide rail, and the fixing device and the driving device are arranged in the ground rail base groove.

[0009] By adopting the technical scheme, the ground rail base groove provides a stable track environment for the sliding of the cross-cutting machine, ensuring that the cross-cutting machine reciprocates between the first cross-cutting station and the second cross-cutting station more stably and accurately. The setting of the sliding rail further reduces the frictional resistance when the cross-cutting machine slides, improving the sliding efficiency. At the same time, the fixing device and the driving device are integrated in the ground rail base groove, effectively reducing the occupied space of the equipment, and improving the compactness and aesthetics of the overall production line.

[0010] Preferably, the fixing device includes a lock block, which is slidingly arranged at the bottom of the cross-cutting machine. The bottom surface of the ground rail base groove is provided with a lock groove matched with the lock block. The lock groove is provided with a plurality of lock grooves corresponding to the first cross-cutting station and the second cross-cutting station. The bottom of the cross-cutting machine is provided with a locking spring for driving the lock block to slide towards the lock groove. The lock groove is provided with an unlocking mechanism for ejecting the lock block out of the lock groove.

[0011] By adopting the technical scheme, the cross-cutting machine can be flexibly switched between the first cross-cutting station and the second cross-cutting station and stably fixed. When the cross-cutting machine moves to the target cross-cutting station, the lock block automatically slides into the lock groove corresponding to the station under the action of the locking spring, realizing rapid locking of the cross-cutting machine and ensuring the stability of the cross-cutting operation. When it is necessary to replace the cross-cutting station, the unlocking mechanism moves the lock block out of the lock groove, so that the cross-cutting machine is quickly unlocked, facilitating the driving device to pull the cross-cutting machine to move to another cross-cutting station, thereby improving the operation efficiency and flexibility of the production line.

[0012] Preferably, the unlocking mechanism includes a lifting frame slidingly arranged in the lock groove. A cam is rotatably connected in the lock groove and abuts 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 the lock block is ejected out of the lock groove.

[0013] By adopting the technical scheme, when it is necessary to unlock the cross-cutting machine, 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 lifted up under the action of the cam, and then the lock block in the lock groove is ejected out of the lock groove. Due to the disengagement of the lock block and the lock groove, the cross-cutting machine is no longer fixedly limited, so that it can be smoothly switched 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, improving the flexibility and automation of the steel plate cross-cutting process.

[0014] Preferably, the cams in all the lock grooves are connected by the same cam shaft. The two ends of the cam shaft are fixedly connected with driven gears. The side surface of the ground rail base groove is slidingly connected with a rack meshing with the driven gears.

[0015] By adopting the technical scheme, the plurality of cams in the plurality of locking grooves can be controlled synchronously. Specifically, by connecting all the cams on the same camshaft, the movement consistency of the cams is ensured, thereby improving the reliability of the transverse shearing machine when switching between different transverse shearing stations. Meanwhile, by using the cooperation of the driven gear and the rack, the camshaft can be conveniently driven to rotate by sliding the rack, thereby controlling the cam 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 transverse shearing machine during the fixing and unlocking process.

[0016] Preferably, the driving device comprises a base fixedly arranged at both ends of the track base groove, and a wire wheel rotatably connected to the base. The wire wheel is connected to the transverse shearing machine through a traction steel cable.

[0017] By adopting the technical scheme, the base is fixedly arranged at both ends of the track base groove, thereby providing stable support for the entire driving device. The wire wheel is rotatably connected to the base and can rotate flexibly. The transverse shearing machine is connected through a traction steel cable, thereby achieving accurate traction of the transverse shearing machine. This design enables the transverse shearing machine to move smoothly and efficiently between the first transverse shearing station and the second transverse shearing station, thereby ensuring the continuity and stability of the steel plate transverse shearing production line.

[0018] Preferably, a control device is arranged 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 of the locking block and the locking groove, and then drive the wire wheel to rotate to slide the transverse shearing machine to the first transverse shearing station or the second transverse shearing station.

[0019] By adopting the technical scheme, the movement and locking operation of the transverse shearing machine are highly integrated. Specifically, the control device can orderly coordinate the actions of the driven gear and the wire wheel, thereby ensuring that the unlocking operation is completed first to avoid mechanical interference when the transverse shearing machine switches stations, and then accurately driving the transverse shearing machine 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 comprises: a fixed frame arranged in the track 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 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 rod threadedly connected in the center hole of the third bevel gear and fixedly connected with the rack; an abutting spring arranged at the bottom of the rack to always abut the screw rod with the third bevel gear; and a clutch mechanism arranged between the shaft of the wire wheel and the second bevel gear to control power transmission.

[0021] By adopting the technical scheme, the operator can realize the whole process control of unlocking, moving and relocking of the cross-cutting machine through simple rotating lever action. The design of the clutch mechanism enables flexible control of power transmission, integrates multiple functions in a single operation device, significantly simplifies the operation process and reduces the operation difficulty. Meanwhile, the use of bevel gear transmission and screw structure ensures the stability and accuracy of power transmission, effectively avoiding the problems of accidental deviation or inaccurate positioning of the cross-cutting machine during movement.

[0022] Preferably, the clutch mechanism comprises a control lever arranged in the rotating shaft of the wire wheel, one end of the control lever extends out of the second bevel gear, the other end of the control lever is fixedly connected with a plurality of clamping blocks, the end of the clamping block extends out of the rotating shaft of the wire wheel, the second bevel gear is fixedly connected with a sleeve ring, the sleeve ring is sleeved outside the rotating shaft of the wire wheel, the sleeve ring is provided with a clamping hole matched with the clamping block, and the rotating shaft of the wire wheel is provided with a clamping spring for driving the clamping block to slide towards the clamping hole.

[0023] By adopting the technical scheme, flexible control of power transmission between the wire wheel and the second bevel gear can be realized. Specifically, when transmission is needed, the clamping block cooperates with the clamping hole on the sleeve ring under the action of the clamping spring, ensuring stable power transmission; when transmission needs to be disconnected, the clamping block can be driven by the control lever to disengage from the clamping hole, 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 stations, but also effectively reduces energy loss and mechanical wear caused by unnecessary transmission.

[0024] A steel plate cross-cutting forming process using the above steel plate cross-cutting production line, comprising the following steps: step S1: simultaneously starting the uncoiler of the first processing line and the second processing line to respectively pay off the steel coil; step S2: feeding the uncoiled steel plate into the corresponding processing line flatting machine for flattening; step S3: when the steel plate of the first processing line travels to the first cross-cutting station, the cross-cutting machine is moved to the first cross-cutting station along the rail base groove by the driving device and locked by the fixing device; step S4: the cross-cutting machine cross-cuts the steel plate in the first processing line, and the cut-off steel plate is sent to the stacking device by the conveyor, while the steel plate of the second processing line is temporarily paused in front of the second cross-cutting station after flattening; step S5: when the steel coil in the first processing line is processed, the control device releases the fixation 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 of the second processing line, and the cut-off steel plate is sent to the stacking device by the conveyor, while the uncoiler in the first processing line is replenished with steel coils; step S7: repeat steps S3-S6, and realize continuous production of the first processing line and the second processing line through the alternating operation of the cross-cutting machine between the first cross-cutting station and the second cross-cutting station.

[0025] By adopting the above technical solutions, the steel plate transverse shearing forming process can significantly improve the operation efficiency and flexibility of the production line. Specifically, by alternating the use of the same transverse shearing machine between the two processing lines and combining the precise driving and fixing devices, the maximum utilization of resources is realized. While the first processing line is performing transverse cutting operation, the second processing line can be prepared in advance, reducing the idle time of the equipment. In addition, when the coil of one processing line is exhausted, the transverse shearing machine can quickly switch to the other processing line to continue operation, ensuring the continuity of the production line and providing sufficient time window for the 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:

[0027] 1. By reciprocating sliding and precise positioning of the transverse shearing machine between the two processing lines, continuous transverse cutting operation of the steel plate in the double-line production mode is realized, effectively avoiding downtime caused by material replacement, and significantly improving the overall efficiency of the production line;

[0028] 2. The design of a single transverse shearing machine serving two processing lines at the same time meets the alternating production requirements while avoiding repeated configuration of equipment, significantly reducing equipment procurement and maintenance costs;

[0029] 3. The cooperation of the driving device and the fixing device ensures the stability and reliability of the transverse shearing machine during switching positions, further optimizing the cutting precision and production rhythm. BRIEF DESCRIPTION OF DRAWINGS
