Description

Technical Field

[0001] The utility model relates to the technical field of copper and copper alloy ingot sawing processing, in particular to a copper and copper alloy ingot cross-over sawing production line. Background Art

[0002] The complete production process of copper and copper alloy plates and strips is batching → adding materials → smelting → casting → sawing → rolling. The production plant includes a raw material span, a melting and casting workshop, and a rolling workshop. The raw material span and the melting and casting workshop are connected. Due to the poor production environment of the melting and casting workshop, the rolling workshop is generally separated from the melting and casting workshop. An electric flatbed car moving along the track is installed between the melting and casting workshop and the rolling workshop to transport the ingots after sawing.

[0003] At present, the production of copper and copper alloy ingots at home and abroad mainly adopts the vertical semi-continuous crystallization casting process, and the copper and copper alloy ingots produced are in a vertical state; the ingots produced by this process have poor head and tail quality due to the ingots formed in the starting casting stage and the end casting shrinking stage. Before the subsequent rolling process, the head and tail parts of the ingots need to be sawed off by a sawing machine; the ingot sawing production lines widely used at present all adopt horizontal feeding devices, and the copper and copper alloy ingots are lifted horizontally to the feeding table of the sawing machine by the lifting clamp of the overhead crane. The ingots on the feeding table are sent to the feeding roller of the sawing machine in a step-by-step manner, and then sent to the sawing machine through the feeding roller for sawing operation;

[0004] The specific process of the existing copper and copper alloy ingots being lifted horizontally from a vertical state to a loading device is as follows: the overhead crane first uses a lifting clamp to lift the upper end (head) of the ingot to lift the finished vertical ingot from the casting well, and then moves the overhead crane to lift the ingot to a temporary storage area for rough ingots, and then slowly drops the ingot. After the bottom (tail) of the ingot touches the ground, the lifting clamp is moved horizontally while slowly dropping the lifting clamp to slowly tilt the ingot, and finally the ingot is laid flat on the ground in the temporary storage area for rough ingots in a horizontal state, and the flattened ingot is then lifted to the loading table of the ingot sawing machine by the lifting clamp;

[0005] The above-mentioned process of lifting the ingot has the following problems: 1. Since the ingot is too long (usually 6.0-8.5 meters) and too heavy (5-25 tons), the lifting process of the ingot is quite dangerous, especially when the ingot is tilted and laid flat, the ingot needs to rotate between the jaws of the lifting clamp. When the rotation angle is too large, it is easy for the ingot to fall off, which is the most dangerous stage in the whole ingot lifting process; once the ingot falls, it may damage the walls, pillars and surrounding equipment of the factory, and even cause casualties; 2. The ingot is in the temporary storage area for raw ingots, which may cause the ingot to fall off and cause damage to the walls, pillars and surrounding equipment of the factory, and even cause casualties; 3. During horizontal storage, in order to avoid the ingots occupying too much space, the horizontally stored ingots are usually perpendicular to the ingot sawing production line. Therefore, when the horizontal ingot is lifted to the loading platform, the ingot needs to be lifted and rotated 90° in the air. When the ingot rotates in the air, a larger operating space is required, and it must be rotated slowly to prevent the ingot from having too much rotational inertia. At the same time, the distance between the ingot and the factory walls, columns, and equipment must be estimated. As a result, the lifting operation is dangerous, difficult, and inefficient. In particular, no personnel or vehicles are allowed to pass on the ground during the lifting and rotation process, which also affects the normal work of other personnel and vehicles.

[0006] After the ingot is sawed and cut, it is hoisted onto an electric flatbed truck for transportation. The ingot is also hoisted and rotated 90° in the air. Therefore, the hoisting process is dangerous, inefficient, and affects the normal work of other personnel and vehicles.

[0007] The existence of the above-mentioned problems must be taken into consideration and solved when building new copper and copper alloy plate and strip production projects. However, due to its structural limitations, the existing ingot sawing production line cannot meet the requirements for solving the above-mentioned problems, so it needs to be improved. Utility Model Content

[0008] In order to overcome the shortcomings in the background technology, the utility model discloses a copper and copper alloy ingot over-span sawing production line, including an ingot turning machine, a feeding roller, a sawing machine and a storage table, wherein the ingot turning machine, the feeding roller and the sawing machine are arranged in sequence in an ingot melting and casting workshop, the storage table is arranged in a rolling and processing workshop, a track is arranged between the sawing machine and the storage table, and a over-span roller car is movably arranged on the track; an adjacent ingot turning machine is arranged with a storage pit, and a storage rack is arranged in the storage pit; the ingots are temporarily stored on the storage rack in a vertical state, shortening the length space occupied by the horizontal storage of the ingots; the ingot turning machine turns the vertical ingot into a horizontal state, eliminating the operation of lifting the ingot by a crane and placing it flat in the temporary storage area for the rough ingots, and the ingot after the sawing process is completed can be automatically moved to the over-span roller car for transportation, completely eliminating the operation of lifting the ingot to an electric flatbed car, thereby greatly improving the lifting safety and production efficiency of the ingot sawing process.

[0009] In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: a copper and copper alloy ingot cross-span sawing production line, which is arranged between the ingot melting and casting workshop and the rolling and processing workshop, and is used for the head and tail sawing processing of copper and copper alloy ingots after casting and the transportation after sawing processing; the ingot melting and casting workshop is provided with a crane and a plurality of melting and casting units arranged in parallel;

[0010] The copper and copper alloy ingot cross-over sawing production line is vertically arranged with several parallel melting and casting units, which includes an ingot turning machine, a feeding roller, a sawing machine, a storage table, and a cross-over roller car, wherein the ingot turning machine, the feeding roller, and the sawing machine are arranged in sequence in the ingot melting and casting workshop, the storage table is arranged in the rolling processing workshop, a track is arranged between the sawing machine and the storage table, and the cross-over roller car moves and is arranged on the track;

[0011] When copper and copper alloy ingots are produced through the cross-span sawing production line, the ingot turning machine is in an upright state, and the overhead crane vertically lifts the ingot to the upright ingot turning machine, and the ingot turning machine flips over to transform the vertical ingot into a horizontal state. This eliminates the need for the overhead crane to lift the ingots from the temporary storage area of ​​the rough ingot to the ingot sawing production line, and the operation of rotating the ingot 90° in the air greatly reduces the danger of ingot lifting operations, while improving the lifting operation efficiency; the ingot is transported to the sawing machine via the feed roller for sawing processing at the head or tail of the ingot; the ingot after sawing is automatically moved to the cross-span roller car, and is transported to the storage table in the rolling processing workshop via the cross-span roller car. This eliminates the need for the previous operation of using a crane to lift the ingot, rotate it 90° in the air, and then place it on an electric flatbed car, greatly improving the transportation efficiency of the ingot after processing, while eliminating the danger of lifting the ingot, and no longer affecting the normal work of other personnel and vehicles.

[0012] Furthermore, adjacent ingot turning machines are provided with storage pits. Since the length of an ingot is usually 6.0-8.5 meters, if the ingot turning machine is directly set on the ground, the center of gravity of the ingot placed on the ingot turning machine will be too high. Once the ingot falls over, it will endanger the lives of surrounding workers or damage surrounding equipment. At the same time, the driving force for the ingot turning machine to turn over will be too large. After the storage pit is set on the side of the ingot turning machine, the lower end of the ingot turning machine will be located in the storage pit in a vertical state, thereby greatly reducing the center of gravity height of the ingot placed on the ingot turning machine. Even if the ingot falls over, the ingot will lean against the edge of the storage pit, so it will not endanger the lives of surrounding workers or damage surrounding equipment. The ingot turning machine is hingedly set on the step surface on the side of the storage pit by a hinged seat set on the base of the ingot turning machine. When the ingot turning machine is turned over, it rotates around the hinge axis and changes from a vertical state to a horizontal state (or from a horizontal state to a vertical state).

[0013] Furthermore, an ingot turning machine driving cylinder is arranged between the ingot turning machine base and the ingot turning machine, and the ingot turning machine driving cylinder drives the ingot turning machine to rotate around the hinge shaft to complete the turning action.

[0014] Furthermore, an ingot turning machine is hingedly provided with an ingot clamping claw driven by an ingot clamping claw driving cylinder. After the ingot falls on the ingot turning machine in a vertical state, the ingot clamping claw is driven by the ingot clamping claw driving cylinder to rotate and clamp the ingot to prevent the ingot from tipping sideways during the turning process.

[0015] Furthermore, one or more storage racks are fixedly installed in the storage pit, and the ingots are stored in a vertical state on the storage racks. Because the storage racks are arranged in the storage pit, the center of gravity height of the ingots placed on the storage racks is greatly reduced. Even if the ingots fall over, the ingots will lean against the edge of the storage pit, so there is no danger to the life safety of surrounding workers or damage to surrounding equipment. The production efficiency of the copper and copper alloy ingot turning and sawing production line is much higher than that of the melting and casting unit. Therefore, the production arrangement of the copper and copper alloy ingot turning and sawing production line is usually single-shift or double-shift, and the enterprise flexibly chooses the off-peak electricity price period for sawing operations to save electricity. In order to save electricity costs, ingots usually need to be temporarily stored for a period of time before sawing. After a batch of copper or copper alloy ingots of the same specifications are all cast, sawing operations are carried out at one time. When the previous method of placing the ingots horizontally in the temporary storage area for rough ingots is adopted, the length of the ingots will occupy too much length space, so a larger temporary storage area for rough ingots has to be set up, resulting in reduced area utilization of the production workshop, indirectly increasing the production cost of the enterprise. After the storage racks are set in the storage pit to store the ingots in a vertical state, the length space occupied by the temporary storage of the ingots is greatly reduced, thereby reducing the production cost of the enterprise.

[0016] Furthermore, the material storage table includes a material storage table base, a material receiving roller, a material storage roller, a material baffle plate assembly, and an ingot driving system; the material receiving roller, the material storage roller, the material baffle plate assembly, and the ingot driving system are fixedly arranged on the upper part of the material storage table base through a support plate; the ingot after sawing processing first enters the material receiving roller of the material storage table, and then is driven by the ingot driving system to enter the material storage roller for temporary storage; the structure in which the material receiving roller and the material storage roller are jointly arranged on the material storage table base can further shorten the length of the copper and copper alloy ingots across the sawing production line.

[0017] Furthermore, a travel switch and a pull-wire sensor are provided on the baffle plate assembly, and the outer end of the pull-wire sensor is fixedly arranged on the driving block assembly of the ingot driving system; the travel switch has two functions: 1. As a limit device for the movement of the first ingot on the storage roller, it controls the stop position of the first ingot on the storage roller; 2. As a measurement reference for the width size of the first ingot placed on the storage roller; the pull-wire sensor is used to dynamically detect the real-time position of the driving block assembly in the ingot driving system; the travel switch and the pull-wire sensor are electrically connected to the control system of the ingot turning and sawing production line, and the control system is preset with the spacing distance between adjacent ingots on the storage roller. In addition, the zero position calibration is required before the pull-wire sensor works; when there is no ingot on the storage roller, the travel switch is in the off state, and when the ingot driving system drives the first ingot after sawing to move to the storage roller and contact with the travel switch, the travel switch closes and sends a closing signal to the control system, and the measurement value output by the pull-wire sensor is transmitted to the control system as the width of the ingot to complete the width measurement of the ingot; after the subsequent sawing is completed, the ingot moves to the storage roller When the ingot is on the storage roller, the control system automatically controls the moving stroke of the drive block assembly according to the closed state of the travel switch, the measured ingot width, the preset spacing distance between adjacent ingots, and the measured value output by the draw rope sensor, thereby controlling the storage position of the ingot on the storage roller and automatically ensuring the spacing distance between adjacent ingots (the spacing distance is used to prevent interference with adjacent ingots when the ingot is lifted by the tongs); in addition, the measured value output by the draw rope sensor is also used to monitor the limit movement distance of the drive block assembly to avoid damage to the ingot drive system caused by the drive block assembly being offside. This method eliminates the limit switch for monitoring the limit movement distance of the drive block assembly and the limit switch for detecting the placement position of each ingot, thereby reducing the number of sensors on the sawing production line; the combined setting structure of the travel switch and the draw rope sensor on the baffle plate assembly realizes the automation of the movement setting of the ingot on the storage roller with a very small number of sensors. When the ingot width changes, there is no need for operator intervention, which reduces the probability of operating errors, reduces the workload of operators, and solves the problem of collision caused by improper operation of operators.

[0018] Furthermore, the ingot driving system includes a driving sprocket combination A, a driving sprocket combination B, a driving block assembly, and a chain. Both the driving sprocket combination A and the driving sprocket combination B are provided with double sprockets to improve the driving capacity of the ingot driving system; the chain rotation is arranged between the sprockets of the driving sprocket combination A and the driving sprocket combination B, and the driving block assembly is fixed on the chain through a sprocket pin; the driving sprocket combination A drives the chain to rotate, and the chain rotation drives the driving block assembly to move, and the driving block assembly drives the ingot to move on the storage roller.

[0019] Furthermore, a driving claw is hingedly provided on the driving block assembly, and the driving claw drives the processed ingot to move on the storage roller table in one direction.

[0020] Furthermore, the roller car includes a roller car body, transfer rollers, wheels, transfer claws, and an electric cylinder; the roller car body is a frame structure formed by welding of steel sections; a number of transfer rollers are provided, and the transfer rollers are rotatably arranged on the upper part of the roller car body through bearing seats, and adjacent transfer roller brackets are connected through sprockets and chains, and one of the transfer rollers is driven to rotate by a motor through the sprocket and chain, thereby driving all the transfer rollers to rotate through the chain, and the rotation of the transfer rollers is used to drive the movement of the ingot on the roller car; the wheel is rotatably arranged at the lower part of the roller car body, and the wheel is connected to a driving motor to drive the wheel to rotate; the transfer claw is hingedly connected to the roller car body, and the electric cylinder is hingedly arranged between the transfer claw and the roller car body, and when the electric cylinder is extended or contracted, the transfer claw is driven to close or open, and when the transfer claw is closed, the ingot placed on the roller car is clamped to prevent the ingot from moving or falling off during transportation.

[0021] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects: the utility model discloses a copper and copper alloy ingot cross-span sawing production line, including an ingot turning machine, a feeding roller, a sawing machine, and a storage table, wherein the ingot turning machine, the feeding roller, and the sawing machine are arranged in sequence in the ingot melting and casting workshop, the storage table is arranged in the rolling and processing workshop, a track is arranged between the sawing machine and the storage table, and a cross-span roller car is movably arranged on the track; an adjacent ingot turning machine is arranged with a storage pit, and a storage rack is arranged in the storage pit; the ingots are temporarily stored on the storage rack in a vertical state, shortening the length space occupied by the horizontal storage of the ingots; the ingot turning machine turns the vertical ingot into a horizontal state, eliminating the operation of lifting the ingot by a crane and placing it flat in the temporary storage area for the rough ingots, and the ingot after the sawing process is completed can be automatically moved to the cross-span roller car for transportation, completely eliminating the operation of lifting the ingot to an electric flatbed car, thereby greatly improving the lifting safety and production efficiency of the ingot sawing process.

[0048] After the melting and casting unit 1 completes the ingot casting, the overhead crane 3 hangs the head of the ingot 4 through the hanging clamp, and hangs the ingot 4 out of the casting well. The tail of the ingot is about 1.0-1.5 meters away from the ground, and is moved horizontally to the upper part of the copper and copper alloy ingot over-span sawing production line or the upper part of the lower storage pit 5, and the ingot 4 is slowly dropped toward the storage rack 2.5, so that the ingot 4 falls into the storage rack 2.5, and the tail of the ingot 4 is stuck in the hook groove, and contacts the anti-skid groove of the anti-skid support plate 2.5.4. The anti-skid groove and the hook column 2.5.1.4 prevent the bottom of the ingot 4 from sliding, and the middle part of the ingot 4 is stuck between the adjacent anti-tilt columns 2.5.3, and leans against the support plate 2.5.2. The anti-tilt column 2.5.3 prevents the ingot 4 from tipping over; the ingot 4 is temporarily stored in the storage rack 2.5;

[0049] After all the ingots 4 of the same specification have been cast, the sawing operation begins; during the sawing operation, the roller car 2.6 stops at the discharge port of the sawing machine: first, the copper and copper alloy ingots are turned over to a vertical state by the ingot turning machine 2.1 of the sawing production line; the overhead crane 3 uses a lifting clamp to hang the head of the ingot 4 stored on the upper storage rack 2.5, rises and leaves the storage rack 2.5, and moves horizontally to the upper part of the adjacent ingot turning machine 2.1, and slowly drops the ingot 4, so that the tail of the ingot 4 falls into the hook of the ingot turning machine frame 2.1.2. When the ingot 4 When the middle part of the ingot turning machine leans against the feeding roller 2.1.4, the driving shaft of the ingot clamping claw driving cylinder 2.1.6 extends, and the ingot clamping claw 2.1.5 closes to clamp the ingot 4 to prevent the ingot 4 from tipping sideways along the axial direction of the feeding roller 2.1.4 during the turning process; the driving shaft of the ingot turning machine driving cylinder 2.1.3 contracts to drive the ingot turning machine 2.1 to turn horizontally, so that the roller surface of the ingot turning machine 2.1 is flush with the roller surface of the feeding roller 2.2, and the ingot clamping claw 2.1.5 is released, and the ingot turning machine 2.1 and the feeding roller 2.2 The feeding rollers rotate synchronously, driving the ingot 4 into the sawing machine 2.3, and sawing the head and tail of the ingot in turn; the sawed ingot 4 is driven by the transfer roller 2.6.2 of the roller car 2.6, and moves to the transfer roller 2.6.2, and the limit switch limits the position of the ingot 4 on the roller car 2.6; when the limit switch on the roller car 2.6 is actuated, the electric cylinder 2.6.5 extends, driving the transfer claw 2.6.4 to rotate and close around the hinge axis to clamp the ingot 4; the wheel 2.6.3 of the roller car 2.6 rotates , driving the over-span roller trolley 2.6 to move; when the over-span roller trolley 2.6 moves into position (controlled by the limit switch) and docks with the receiving roller 2.4.2 of the storage platform 2.4, the electric cylinder 2.6.5 contracts, driving the transfer claw 2.6.4 to rotate and open around the hinge axis, releasing the ingot 4; the transfer roller 2.6.2 rotates synchronously with the transfer roller of the receiving roller 2.4.2, driving the ingot 4 to move onto the receiving roller 2.4.2 of the storage platform 2.4 (the position of the ingot 4 on the receiving roller 2.4.2 is controlled by the limit switch);

[0050] After the ingot 4 moves to its position on the receiving roller 2.4.2, the ingot drive system 2.4.5 is started, and the drive block assembly 2.4.5.3 returns to its original position first: the drive motor on the drive sprocket assembly A2.4.5.1 rotates counterclockwise, the drive sprocket rotates counterclockwise, and the sprocket drives the chain 2.4.5.4 to rotate, driving the drive block assembly 2.4.5.3 to move to the outside of the receiving roller 2.4.2 first (when the drive block assembly 2.4.5.3 passes through the lower part of the ingot 4, the drive claw 2.4.5.3. 2 automatically retracts in the driving claw groove of the driving block 2.4.5.3.1). During the movement of the driving block assembly 2.4.5.3, the pull rope of the traction rope sensor 2.4.4.3 stretches, and the traction rope sensor 2.4.4.3 measures the moving position of the driving block assembly 2.4.5.3 to prevent it from moving offside. After the driving block assembly 2.4.5.3 returns to its original position, the driving motor on the driving sprocket assembly A2.4.5.1 rotates clockwise, the driving sprocket rotates clockwise, and the sprocket drives the chain 2.4.5 .4 rotates, driving the driving block assembly 2.4.5.3 to move toward the baffle plate assembly 2.4.4. At this time, the driving claw 2.4.5.3.2 automatically rises under the action of the torsion spring 2.4.5.3.5, pushing the ingot 4 located on the receiving roller 2.4.2 to transfer to the storage roller 2.4.3, and moving along the storage roller 2.4.3 toward the baffle plate assembly 2.4.4; in the process of the ingot 4 moving toward the baffle plate assembly 2.4.4, the pull rope of the traction rope sensor 2.4.4.3 is shortened, and the pull rope sensor The sensor 2.4.4.3 measures the moving position of the driving block assembly 2.4.5.3; when the ingot 4 contacts the travel switch 2.4.4.2, the travel switch 2.4.4.2 is closed, and the closing signal is transmitted to the control system, and the control system controls the driving motor on the driving sprocket assembly A2.4.5.1 to stop running. The control system records the measurement value of the pull rope sensor 2.4.4.3 at this time, which is the width of the ingot 4, and the value is also the placement position value of the first ingot 4 on the storage roller 2.4.3;

[0051] The control system calculates the position value of the second ingot 4 on the storage roller 2.4.3 and the position value of the third ingot 4 on the storage roller 2.4.3 driven by the driving block assembly 2.4.5.3 according to the measured width of the ingot 4, the position value of the previous ingot 4, and the interval distance between adjacent ingots preset in the system, until the position value of the nth ingot 4 that can be accommodated by the storage roller 2.4.3;

[0052] When the second ingot 4 has completed sawing, it is transported by the roller conveyor 2.6 and enters the receiving roller 2.4.2, and the drive block assembly 2.4.5.3 returns to its original position; the drive motor on the drive sprocket assembly A2.4.5.1 is controlled to rotate counterclockwise to drive the second ingot 4 to move toward the baffle plate assembly 2.4.4; during the movement of the drive block assembly 2.4.5.3, the pull rope sensor 2.4.4.3 measures the moving position of the drive block assembly 2.4.5.3, and when the drive block assembly 2.4.5.3 moves to the position value of the second ingot 4 calculated by the control system, the control system controls the drive motor to stop rotating, and the second ingot 4 moves into place;

[0053] The above-mentioned transfer and movement process of the second ingot 4 is repeated until all n ingots 4 are moved to the storage platform 2.4, and the transfer of the ingots 4 from the melting and casting workshop to the rolling workshop is completed.
