Description

Technical Field

[0001] This invention relates to the field of copper and copper alloy ingot sawing technology, specifically to a copper and copper alloy ingot turning and sawing production line. Background Technology

[0002] The current domestic and international production of copper and copper alloy ingots mainly adopts the vertical semi-continuous crystallization casting process, producing copper and copper alloy ingots in a vertical state. Due to the poor quality of the ingots formed during the initial casting stage and the final shrinkage stage of casting, the ingots at the beginning and end of the casting process need to be sawed off by a sawing machine before subsequent rolling processing. Currently, the widely used ingot sawing production lines all use horizontal feeding devices. The copper and copper alloy ingots are lifted horizontally by a crane using clamps and finally placed on the feeding platform of the sawing machine. The ingots on the feeding platform are then fed to the feeding roller conveyor of the sawing machine in a stepping manner, and then fed into the sawing machine for sawing operations.

[0003] The specific process of transporting existing copper and copper alloy ingots from a vertical position to a horizontal position to the loading device is as follows: The overhead crane first uses a clamp to lift the upper end (head) of the ingot and lift the completed vertical ingot out of the casting well. The overhead crane moves to lift the ingot to the temporary storage area for raw ingots. Then the ingot is slowly lowered. After the bottom (tail) of the ingot touches the ground, the clamp is moved horizontally while the clamp is slowly lowered to tilt the ingot. Finally, the ingot is placed flat to a horizontal position. The flattened ingot is then lifted by the clamp to the loading platform of the ingot sawing machine.

[0004] The above-mentioned process of hoisting ingots presents the following problems: 1. Due to the excessive length (usually 6.0-8.5 meters) and weight (5-25 tons) of the ingots, the hoisting process is quite dangerous, especially during the tilting and leveling process. Because the ingot needs to rotate between itself and the hoisting clamps, a large rotation angle can easily cause the ingot to fall, making this the most dangerous part of the entire hoisting process. If an ingot falls, it may damage factory walls, pillars, and surrounding equipment, and could even cause personal injury or death. 2. When ingots are temporarily stored horizontally in the raw ingot storage area, to avoid them occupying too much space, they are usually perpendicular to the ingot sawing production line. Therefore, when hoisting horizontal ingots onto the loading platform... The process involves several challenges: 1) Lifting the ingot and rotating it 90° in the air. This requires a large operating space and slow rotation to prevent excessive moment of inertia. Simultaneously, the distance between the ingot and factory walls, pillars, and equipment must be carefully estimated. This results in high risk, difficulty, and low efficiency in the lifting operation. Furthermore, no personnel or vehicles are allowed on the ground during the lifting and rotation process, impacting the normal work of other personnel and vehicles. 2) After sawing, the ingot is lifted onto an electric flatbed truck for transport, again requiring a 90° rotation in the air. Therefore, existing methods for lifting and transporting copper and copper alloy ingots after sawing present significant risks, low efficiency, and disruption to the normal work of other personnel and vehicles, necessitating urgent solutions. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this invention discloses a copper and copper alloy ingot turning and sawing production line. An ingot turning machine is installed at the front end of the sawing production line, and a rotary storage platform is installed at the rear end. When the ingot is hoisted from the casting well to the turning machine, it remains in a vertical position. The ingot is turned from vertical to horizontal on the turning machine, eliminating the need for the previous operation of using an overhead crane to hoist the ingot and place it flat in the temporary ingot storage area, and the operation of rotating the ingot 90° in the air. After processing, the ingot completes a 90° horizontal rotation on the rotary storage platform, eliminating the need for an overhead crane to hoist the ingot and complete the 90° rotation in the air.

[0006] To achieve the aforementioned objective, the present invention employs the following technical solution: a copper and copper alloy ingot turning and sawing production line, set up within an ingot melting and casting workshop, for the head and tail sawing processing of copper and copper alloy ingots after casting; the ingot melting and casting workshop is equipped with an overhead crane and several melting and casting units arranged in parallel, and the turning and sawing production line is arranged in parallel with the several melting and casting units arranged in parallel; an ingot rolling processing workshop is arranged adjacent to the ingot melting and casting workshop, and an electric flatbed cart that moves back and forth along a track is arranged between the ingot melting and casting workshop and the ingot rolling processing workshop, and the ingots processed by the turning and sawing production line are transported to the ingot rolling processing workshop by the electric flatbed cart;

[0007] The ingot flipping and sawing production line includes an ingot flipping machine, a feeding roller conveyor, a sawing machine, and a rotary storage platform arranged in sequence. The ingot flipping machine flips the vertically positioned ingot to a horizontal position. The feeding roller conveyor transports the ingot to the sawing machine, which cuts the head and tail ends of the ingot. The rotary storage platform temporarily stores the sawn ingot and rotates it 90° horizontally. During operation, the ingot flipping machine is in an upright position. An overhead crane vertically lifts the ingot onto the upright machine, which flips it to transform the vertical ingot into a horizontal position. The ingot is then fed... The roller conveyor transports the ingots to the sawing machine, eliminating the need for the previous overhead crane to hoist the ingots flat and place them in the temporary ingot storage area, as well as the operation of rotating the ingots 90° in the air. This greatly reduces the danger of ingot hoisting operations and improves hoisting efficiency. After sawing, the ingots are temporarily stored on a rotary storage platform. The rotary storage platform rotates horizontally, completing a 90° rotation of the ingots in the horizontal direction. This eliminates the need for an overhead crane to hoist the ingots and complete the 90° rotation in the air, greatly improving the efficiency of ingot hoisting operations, reducing the danger of hoisting operations, and not affecting the normal work of other personnel and vehicles.

[0008] Furthermore, a storage pit is provided on the side of the adjacent ingot tilting machine. Since the length of the ingot is usually 6.0-8.5 meters, if the ingot tilting machine is placed directly on the ground, the center of gravity of the ingot placed on the tilting machine will be too high. If the ingot tilts, it will endanger the lives of nearby workers or damage the surrounding equipment. At the same time, the driving force of the tilting machine will be too large. With the storage pit on the side of the tilting machine, the lower end of the tilting machine will be located in the storage pit when it is in a vertical state. This greatly reduces the height of the center of gravity of the ingot placed on the tilting machine. Even if the ingot tilts, it will lean against the edge of the storage pit, so it will not endanger the lives of nearby workers or damage the surrounding equipment. The tilting machine is hinged to the side of the storage pit by a hinge seat set on the tilting machine base. When the tilting machine is tilted, it rotates around the hinge axis, changing from a vertical state to a horizontal state.

[0009] Furthermore, a tilting machine drive cylinder is installed between the tilting machine base and the tilting machine. The tilting machine drive cylinder drives the tilting machine to rotate around the hinge shaft to complete the tilting action.

[0010] Furthermore, the ingot flipping machine is hinged with ingot-clamping claws driven by ingot-clamping claw hydraulic cylinders. After the ingot falls onto the ingot flipping machine in a vertical state, the ingot-clamping claws are driven by the ingot-clamping claw hydraulic cylinders to rotate and clamp the ingot, preventing the ingot from tilting to the side during the flipping process.

[0011] Furthermore, one or more storage racks are fixedly installed in the storage pit, and the ingots are stored vertically on the racks. Because the storage racks are located inside the storage pit, the center of gravity of the ingots placed on the racks is greatly reduced. Even if an ingot tipps over, it will rest against the edge of the storage pit, thus preventing endangerment of nearby 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 schedule of the copper and copper alloy ingot turning and sawing production line is usually single-shift or double-shift. Enterprises can flexibly choose to carry out sawing operations during off-peak electricity price periods to save energy. To save on electricity costs, ingots typically need to be temporarily stored before sawing. Once a batch of copper or copper alloy ingots of the same specifications has been cast, the sawing operation is carried out all at once. In the past, when ingots were placed horizontally in the temporary storage area, the length of the ingots would occupy too much space, so a large temporary storage area had to be set up, which reduced the utilization rate of the production workshop area and indirectly increased the company's production costs. However, by using storage racks in the storage pit to store ingots vertically, the length of space occupied by temporary ingot storage is greatly reduced, thereby reducing the company's production costs.

[0012] Furthermore, the rotary storage platform is movable within the rotary table pit; a track is installed within the rotary table pit, and the rotary storage platform moves horizontally along the track; when the ingot is being sawed, the rotary storage platform needs to be properly connected with the sawing machine. When the rotary storage platform rotates horizontally, the ingot temporarily stored on the rotary storage platform will interfere with the sawing. Therefore, before the rotary storage platform rotates horizontally, it must move along the track within the rotary table pit and move a certain distance away from the sawing machine.

[0013] Furthermore, the rotary storage platform includes a rotary table, a receiving roller conveyor, a storage roller conveyor, a baffle plate assembly, and an ingot driving system. The rotary table drives the other components mounted on it to rotate horizontally. The receiving roller conveyor receives the sawn ingots, and the storage roller conveyor temporarily stores the sawn ingots. The baffle plate assembly detects the first ingot and prevents it from accidentally falling off the rotary storage platform. (It should be noted that the baffle plate assembly includes a baffle plate; under normal circumstances, the first ingot does not contact the baffle plate, meaning the baffle plate does not limit the movement of the first ingot and prevent impulsive movement of the ingot.) (Excessive damage to the baffle plate) The ingot drive system is used to drive the ingot from the receiving roller conveyor to the storage roller conveyor and on the turntable storage roller conveyor, and to ensure the spacing between adjacent ingots on the storage roller conveyor (i.e., the storage position of the ingot on the storage roller conveyor). This spacing is used to ensure that the lifting clamp can lift the ingot normally. The receiving roller conveyor, storage roller conveyor, baffle plate assembly, and ingot drive system are fixedly set on the upper part of the turntable by the support plate. The rotation of the turntable drives the receiving roller conveyor, storage roller conveyor, baffle plate assembly, and ingot drive system to rotate as a whole. The sawn ingot first enters the receiving roller conveyor, and then enters the storage roller conveyor through the ingot drive system.

[0014] Furthermore, the baffle assembly is equipped with a limit switch and a pull rope sensor. The outer end of the pull rope sensor is fixedly mounted on the drive block assembly of the ingot driving system. The limit switch has two functions: 1. As a limit device for the movement of the first ingot on the storage roller conveyor, controlling the stop position of the first ingot on the storage roller conveyor; 2. As a measurement reference for the width of the first ingot placed on the storage roller conveyor. The pull rope sensor is used to dynamically detect the real-time position of the drive block assembly in the ingot driving system. Both the limit switch and the pull rope sensor are electrically connected to the control system of the ingot turning and sawing production line. The control system has a preset interval distance between adjacent ingots on the storage roller conveyor. In addition, the pull rope sensor needs to be calibrated at zero point before it works. When there is no ingot on the storage roller conveyor, the limit switch is in the open state. When the ingot driving system drives the first sawn ingot to move to the storage roller conveyor and contact the limit switch, the limit switch closes and sends a closing signal to the control system. At this time, the measurement value output by the pull rope sensor is transmitted to the control system as the width of the ingot, completing the width measurement of the ingot. After the ingots are sawn and moved onto the storage roller conveyor, the control system automatically controls the movement of the drive block assembly based on the closed state of the limit switches, the measured width of the ingots, the preset interval between adjacent ingots, and the measured values ​​output by the pull rope sensor. This controls the storage position of the ingots on the storage roller conveyor and automatically ensures the interval between adjacent ingots. In addition, the measured values ​​output by the pull rope sensor are also used to monitor the limit movement distance of the drive block assembly, preventing the drive block assembly from overshooting and causing damage to the ingot drive system. This method eliminates the need for limit switches to monitor the limit movement distance of the drive block assembly and limit switches to detect the position of each ingot, reducing the number of sensors on the sawing production line. The combination of limit switches and pull rope sensors on the baffle plate assembly automates the movement of ingots on the storage roller conveyor with a minimal number of sensors. Even when the width of the ingots changes, no operator intervention is required, reducing the probability of operational errors, alleviating the workload of operators, and solving the problem of collisions caused by improper operation.

[0015] Furthermore, the ingot casting drive system includes drive sprocket assembly A, drive sprocket assembly B, drive block assembly, and chain. Both drive sprocket assembly A and drive sprocket assembly B are equipped with double sprockets to improve the driving capability of the ingot casting drive system. The chain rotation is located between the sprockets of drive sprocket assembly A and drive sprocket assembly B. The drive block assembly is fixedly mounted on the chain via sprocket pins. Drive sprocket assembly A drives the chain to rotate, and the chain rotation drives the drive block assembly to move. The drive block assembly drives the ingot to move on the storage roller conveyor.

[0016] Furthermore, a drive claw is hinged to the drive block assembly, and the drive claw drives the ingot to move unidirectionally on the storage roller conveyor.

[0017] Due to the adoption of the above-described technical solution, the present invention has the following beneficial effects: The copper and copper alloy ingot turning and sawing production line disclosed in this invention has a storage rack and an ingot turning machine at the front end of the existing sawing production line, and a rotary storage platform at the rear end of the sawing production line; when the ingot is hoisted from the casting well to the storage rack and the ingot turning machine, it is always in a vertical state. The ingot is turned from a vertical state to a horizontal state by the ingot turning machine, eliminating the previous operation of hoisting the ingot flat in the temporary storage area of ​​the raw ingot and the operation of hoisting the ingot and rotating it 90° in the air, which greatly reduces the danger of ingot hoisting operation; at the same time, the vertical storage of the ingot on the storage rack also greatly reduces the length space occupied by the temporary storage of the ingot; after processing, the ingot completes a 90° horizontal rotation on the rotary storage platform, eliminating the need to use an overhead crane to hoist the ingot and complete the 90° rotation in the air, which greatly improves the efficiency and safety of ingot hoisting operation, and does not affect the normal work of other personnel and vehicles.

Figure 1 , 2 The instruction manual includes... Figure 2 The diagram shows the rotary storage platform 2.4 rotating 90° horizontally. The ingot melting and casting workshop is equipped with an overhead crane 3 and several parallel melting and casting units 1. The ingot turning and sawing production line 2 is parallel to the parallel melting and casting units 1. An ingot rolling and processing workshop is adjacent to the ingot melting and casting workshop, and an electric flatbed cart 7 moves back and forth along a track between them. The ingots 4 processed by the ingot turning and sawing production line 2 are transported to the ingot rolling and processing workshop via the electric flatbed cart 7. The placement direction of the ingots 4 on the electric flatbed cart 7 is the same as the direction of movement of the electric flatbed cart 7.

[0039] See the instruction manual appendix Figure 3 , 4 The ingot turning and sawing production line 2 includes an ingot turning machine 2.1, a feeding roller conveyor 2.2, a sawing machine 2.3, and a rotary storage platform 2.4 arranged in sequence. A storage pit 5 is located at the left end of the ingot turning and sawing production line 2, and a rotary platform pit 6 is located at the right end. The ingot turning machine 2.1 is hinged to the right side of the storage pit 5. A storage rack 2.5 is also fixedly installed in the storage pit 5 relative to the ingot turning machine 2.1. The rotary storage platform 2.4 is movable within the rotary platform pit 6. The instruction manual is attached. Figure 3 It shows that only one storage rack 2.5 is fixedly installed in the storage pit 5; the instruction manual is attached. Figure 4 The manual shows that three storage racks 2.5 are fixedly installed inside the storage pit 5. The two storage racks 2.5 closest to the ingot turning machine 2.1 are shorter, and there is a gap between them to facilitate the hoisting of ingots 4 stored on the storage racks 2.5 farther from the ingot turning machine 2.1 to the ingot turning machine 2.1. Additionally, the manual includes... Figure 4 It also shows the state of the rotary storage platform 2.4 rotating horizontally by 90°, at which time the length direction of the ingot on the rotary storage platform 2.4 is the same as the moving and transporting direction of the electric flatbed trolley 4;

[0040] See the instruction manual appendix Figure 5 , 6The ingot turning machine 2.1 includes an ingot turning machine base 2.1.1, an ingot turning machine frame 2.1.2, an ingot turning machine drive cylinder 2.1.3, a feeding roller 2.1.4, an ingot clamping claw 2.1.5, and an ingot clamping claw drive cylinder 2.1.6. The ingot turning machine base 2.1.1 is made of metal, with a pair of hinge ears on the upper left end. The ingot turning machine base 2.1.1 is fixedly set on the stepped surface on the right side of the storage pit 5. The ingot turning machine frame 2.1.2 is a frame structure welded from structural steel, with a hook head on its left end and a hinge hole at its lower part. The hinge hole is hinged to the hinge ears of the ingot turning machine base 2.1.1 through a hinge shaft. Several feeding rollers 2.1.4 are rotatably set on the upper part of the ingot turning machine frame 2.1.2 through bearing seats. The feeding rollers 2.1.4 are connected by sprockets and chains. The sprockets are driven by a motor to rotate, which in turn drives all the feeding rollers 2.1.4 to rotate via the chains. The ingot turning machine drive cylinder 2.1.3 is hinged between the ingot turning machine frame 2.1.2 and the ingot turning machine base 2.1.1. When the drive shaft of the ingot turning machine drive cylinder 2.1.3 extends, the ingot turning machine 2.1 is driven in a vertical position, with an angle of 10-20° to the vertical direction, thus tilting. When the drive shaft of the ingot turning machine drive cylinder 2.1.3 retracts, the ingot turning machine 2.1 is driven in a horizontal position, at which point the roller surface of the ingot turning machine 2.1 is flush with the roller surface of the feeding roller conveyor 2.2. (See the attached instruction manual.) Figure 7 , 8 The ingot clamping claw 2.1.5 is hinged on both sides of the ingot turning machine frame 2.1.2. The ingot clamping claw driving cylinder 2.1.6 is hinged between the lower part of the ingot clamping claw 2.1.5 and the bottom of the ingot turning machine frame 2.1.2. When the drive shaft of the ingot clamping claw driving cylinder 2.1.6 extends, the ingot clamping claw 2.1.5 closes and clamps the ingot 4 to prevent it from tipping over during the turning process. When the drive shaft of the ingot clamping claw driving cylinder 2.1.6 retracts, the ingot clamping claw 2.1.5 opens, and the ingot 4 moves onto the feeding roller table 2.2 when the feeding roller 2.1.4 rotates.

[0041] See the instruction manual appendix Figure 9 , 10The storage rack 2.5 includes a storage rack frame 2.5.1, a support plate 2.5.2, an anti-tilting column 2.5.3, and an anti-slip support plate 2.5.4.

Several anti-slip grooves are provided on the upper surface of the anti-slip support plate 2.5.4; when the ingot 4 is placed on the storage rack 2.5, the bottom of the ingot 4 is placed in the hook groove and abuts against the anti-slip support plate 2.5.4. The anti-slip grooves and hook columns 2.5.1.4 prevent the bottom of the ingot 4 from sliding, and the middle part of the ingot 4 is placed between the adjacent anti-tilting columns 2.5.3 to prevent the ingot 4 from tipping over;

[0042] See the instruction manual appendix Figure 11 A track 6.1 is fixedly installed at the bottom of the rotary table pit 6. A traveling wheel 2.4.1.3 is rotatably installed at the bottom of the rotary storage platform 2.4. The rotary storage platform 2.4 is set on the upper part of the track 6.1 via the traveling wheel 2.4.1.3. The traveling wheel 2.4.1.3 is driven to rotate by a motor, driving the rotary storage platform 2.4 to move horizontally along the track 6.1.

[0043] See the instruction manual appendix Figure 12The rotary storage platform 2.4 includes a rotary table 2.4.1, a receiving roller conveyor 2.4.2, a storage roller conveyor 2.4.3, a baffle plate assembly 2.4.4, and an ingot casting drive system 2.4.5. The receiving roller conveyor 2.4.2, storage roller conveyor 2.4.3, baffle plate assembly 2.4.4, and ingot casting drive system 2.4.5 are fixedly mounted on the upper part of the rotary table 2.4.1 via a support plate. Two sets of receiving roller conveyors 2.4.2 are provided, symmetrically arranged in front of the support plate. There is a distance between 2.4.2 and 2.4.2. The receiving roller conveyor 2.4.2 is equipped with a drive mechanism to drive the feeding roller on the receiving roller conveyor 2.4.2 to rotate. There are also two sets of storage roller conveyors 2.4.3, symmetrically arranged at the rear of the storage roller conveyor 2.4.3, and there is also a distance between the two sets of storage roller conveyors 2.4.3. The baffle plate assembly 2.4.4 is fixedly arranged at the upper rear end of the support plate. The ingot casting drive system 2.4.5 is arranged through the front and rear ends of the support plate. It should be noted that the receiving roller conveyor 2.4.2 has a distance between 2.4.2 and 2.4.2. The receiving roller conveyor 2.4.2 is equipped with a drive mechanism to drive the feeding roller on the receiving roller conveyor 2.4.2 to rotate. There are also two sets of storage roller conveyors 2.4.3, symmetrically arranged at the rear end of the storage roller conveyor 2.4.3, and there is also a distance between the two sets of storage roller conveyors 2.4.3. The baffle plate assembly 2.4.4 is fixedly arranged at the upper rear end of the support plate. The ingot casting drive system 2.4.5 is arranged through the front and rear ends of the support plate. It should be noted that the receiving roller conveyor 2.4.2 has a distance between 2.4.2 and 2.4.2. The ... 4.2 Originally, the discharge roller conveyor of the copper and copper alloy ingot turning sawing production line was fixed on the ground. In the technical solution of this patent application, it is divided into two sections and fixed on the rotary table 2.4.1. The reason is that if the receiving roller conveyor 2.4.2 is still fixed on the ground at the end of the sawing production line, the rotary storage platform 2.4 has two settings: 1. The rotary storage platform 2.4 is moved to the side of the discharge roller conveyor; 2. The rotary storage platform 2.4 is moved to the end of the discharge roller conveyor. However, both settings of the rotary storage platform 2.4 need to consider the horizontal movement of the discharge roller conveyor during rotation. Therefore, the overall width or length of the sawing production line will be too large, resulting in a decrease in the area utilization rate of the smelting and casting production workshop and an increase in the overall project cost. After adopting the technical solution of this patent application, the width or length of the sawing production line is greatly reduced, the area utilization rate of the smelting and casting production workshop is improved, and the overall project cost is reduced.

[0044] See the instruction manual appendix Figure 13 The rotary table 2.4.1 includes a rotary table chassis 2.4.1.1, a rotary support 2.4.1.2, and traveling wheels 2.4.1.3. The rotary support 2.4.1.2 is rotatably mounted on the upper part of the rotary table chassis 2.4.1.1. Gears are provided on the outer circumference of the rotary support 2.4.1.2. The gears mesh with a drive gear, which is driven to rotate by a motor. The drive gear drives the rotary support 2.4.1.2 to rotate. The traveling wheels 2.4.1.3 are rotatably mounted on the lower part of the rotary table chassis 2.4.1.1 and are driven to rotate by a motor.

[0045] See the instruction manual appendix Figure 14The baffle assembly 2.4.4 includes a baffle 2.4.4.1, a limit switch 2.4.4.2, and a pull rope sensor 2.4.4.3. The baffle 2.4.4.1 is fixedly installed on the upper rear side of the support plate of the rotary storage platform 2.4. The limit switch 2.4.4.2 and the pull rope sensor 2.4.4.3 are fixedly installed on the front of the baffle 2.4.4.1. The pull rope sensor 2.4.4.3 is provided with a pull rope that can be pulled out or retracted.

[0046] See the instruction manual appendix Figure 15 The ingot casting drive system 2.4.5 includes drive sprocket assembly A2.4.5.1, drive sprocket assembly B2.4.5.2, drive block assembly 2.4.5.3, and chain 2.4.5.4. Both drive sprocket assemblies A2.4.5.1 and B2.4.5.2 are equipped with sprocket supports, each with two sprockets rotatably mounted on it. Drive sprocket assembly A2.4.5.1 also has a drive motor for driving the two sprockets on it. Drive sprocket assembly A2.4.5.1 is fixedly mounted on the upper rear side of the support plate of the rotary storage platform 2.4, near the baffle plate assembly 2.4.4. The drive sprocket assembly B2.4.5.2... 2.4.5.2 The drive block assembly 2.4.5.2 is fixedly installed on the upper front side of the support plate of the rotary storage platform 2.4. Two chains 2.4.5.4 are rotatably installed between the sprockets of drive sprocket assembly A 2.4.5.1 and drive sprocket assembly B 2.4.5.2. The drive block assembly 2.4.5.3 is fixedly installed on the upper part of the two chains. The outer end of the pull rope of the pull rope sensor 2.4.4.3 is fixedly connected to the drive block assembly 2.4.5.3. Before the sawing production line starts production, the drive block assembly 2.4.5.3 is moved to be flush with the limit switch 2.4.4.2. Then the measured value output by the pull rope sensor 2.4.4.3 to the control system is zeroed, and the zero point calibration of the pull rope sensor 2.4.4.3 is completed.

[0047] See the instruction manual appendix Figure 16 , 1718: The drive block assembly 2.4.5.3 includes a drive block 2.4.5.3.1 and a drive claw 2.4.5.3.2. The drive block 2.4.5.3.1 has a drive claw groove in the middle. The drive claw 2.4.5.3.2 is hinged in the drive claw groove of the drive block 2.4.5.3.1 through a drive claw pin 2.4.5.3.4. The drive block 2.4.5.3.1 is connected to the chain 2.4.5.4 through two sprocket pins 2.4.5.3.3, wherein the sprocket pins of adjacent drive claw pins 2.4.5.3.4... A torsion spring 2.4.5.3.5 is also provided on shaft 2.4.5.3.5. The two torsion arms of the torsion spring 2.4.5.3.5 abut against the drive block 2.4.5.3.1 and the drive claw 2.4.5.3.2 respectively. Under normal conditions, the drive claw 2.4.5.3.2 is in a raised state under the action of the torsion arms of the torsion spring 2.4.5.3.5. When the drive block assembly 2.4.5.3 moves away from the baffle plate assembly 2.4.4, it will be pressed down and retracted into the drive claw groove of the drive block 2.4.5.3.1 when it encounters the ingot 4.

[0048] After the casting unit 1 completes casting, the overhead crane 3 uses clamps to lift the head of the ingot 4 and remove it from the casting well. The tail of the ingot is about 1.0-1.5 meters above the ground. It is then moved horizontally to the upper part of the storage pit 5 and aligned with the storage rack 2.5 before being slowly lowered into the storage rack 2.5. The tail of the ingot 4 is wedged in the hook groove and abuts against the anti-slip groove of the anti-slip support plate 2.5.4. The anti-slip groove and the hook column 2.5.1.4 prevent the bottom of the ingot 4 from sliding. The middle of the ingot 4 is wedged between adjacent anti-tilting columns 2.5.3 and leans against the support plate 2.5.2. The anti-tilting columns 2.5.3 prevent the ingot 4 from tipping over. The ingot 4 is temporarily stored in the storage rack 2.5.

[0049] After all ingots 4 of the same specification have been cast, the sawing operation begins: First, the ingot flipper 2.1 is flipped to a vertical position; the overhead crane 3 lifts the head of the ingot 4 stored on the storage rack 2.5 using clamps, rises off the storage rack 2.5, moves horizontally to the upper part of the ingot flipper 2.1, and slowly lowers the ingot 4 so that the tail of the ingot 4 falls into the hook of the ingot flipper frame 2.1.2. When the middle part of the ingot 4 leans against the feeding roller 2.1.4, the drive shaft of the ingot clamping claw driving cylinder 2.1.6 extends, and the ingot clamping claw 2.1.5 closes, clamping the ingot 4 and preventing the ingot 4 from falling during the flipping process. During the process, the ingot tilts laterally along the axial direction of the feeding roller 2.1.4; the drive shaft of the ingot turning machine drive cylinder 2.1.3 retracts, driving the ingot turning machine 2.1 to flip and become horizontal, so that the roller surface of the ingot turning machine 2.1 is flush with the roller surface of the feeding roller 2.2. The ingot clamping claw 2.1.5 is released, and the feeding rollers of the ingot turning machine 2.1 and the feeding roller 2.2 rotate synchronously. The ingot 4 first moves to the feeding roller 2.2, and then is driven by the feeding roller 2.2 into the sawing machine 2.3 to saw off the head and tail of the ingot. Finally, it is driven by the receiving roller 2.4.2 and completely enters the receiving roller 2.4.2.

[0050] The operator starts the ingot drive system 2.4.5. The drive block assembly 2.4.5.3 first returns to its original position: the drive motor on the drive sprocket assembly A2.4.5.1 rotates counterclockwise, the drive sprocket rotates counterclockwise, the sprocket drives the chain 2.4.5.4 to rotate, causing the drive block assembly 2.4.5.3 to move to the outside of the receiving roller conveyor 2.4.2 (as the drive block assembly 2.4.5.3 passes under the ingot 4, the drive claw 2.4.5.3.2 automatically retracts into the drive block 2.4). In the drive claw slot of 2.4.3.1, during the movement of the drive block assembly 2.4.5.3, the pull rope of the traction rope sensor 2.4.4.3 extends, and the traction rope sensor 2.4.4.3 measures the moving position of the drive block assembly 2.4.5.3 to prevent it from moving out of its designated position; after 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 rotates clockwise, the drive sprocket rotates clockwise, and the sprocket drives the chain 2.4.5.4 to rotate, driving... The drive block assembly 2.4.5.3 moves towards the baffle plate assembly 2.4.4. At this time, the drive 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 conveyor 2.4.2 to the storage roller conveyor 2.4.3, and moves along the storage roller conveyor 2.4.3 towards the baffle plate assembly 2.4.4. During the process of the ingot 4 moving towards the baffle plate assembly 2.4.4, the pull rope of the traction rope sensor 2.4.4.3 shortens, and the pull rope sensor 2... 4.4.3 Measure the moving position of the drive block assembly 2.4.5.3; When the ingot 4 contacts the limit switch 2.4.4.2, the limit switch 2.4.4.2 closes, and the closing signal is transmitted to the control system. The control system controls the drive motor on the drive 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. This value is the width of the ingot 4, and it is also the position value of the first ingot 4 on the storage roller conveyor 2.4.3.

[0051] The control system calculates the position values ​​of the second ingot 4 driven by the drive block assembly 2.4.5.3 on the storage roller conveyor 2.4.3, the position values ​​of the third ingot 4 on the storage roller conveyor 2.4.3, and so on, based on the measured width of ingot 4, the position value of the previous ingot 4, and the preset interval distance between adjacent ingots in the system, until the position value of the nth ingot 4 that the storage roller conveyor 2.4.3 can accommodate.

[0052] After the second ingot 4 is sawn, it enters the receiving roller conveyor 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 rotates counterclockwise, driving the second ingot 4 to move towards the baffle 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 position of the drive block assembly 2.4.5.3. 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] Repeat the above process of moving the second ingot 4 until all n ingots 4 have been moved into place;

[0054] Once the nth ingot 4 is in position, the control system shuts down the translation program of ingot 4 on the rotary storage platform 2.4, meaning the ingot drive system 2.4.5 stops operating. At this point, the operator starts the rotary storage platform 2.4 to rotate. After starting the rotation of the rotary storage platform 2.4, it first moves to the right under the drive of the traveling wheels 2.4.1.3 (limit switches are provided on the track 6.1). After moving into position, the motor drives the drive gear to rotate, which in turn drives the rotary support 2.4.1.2 to rotate clockwise until the rotary support 2.4.1.2 has rotated 90°. At this point, the rotary storage platform 2.4.1.2 is complete. The length direction of the ingot 4 on the 4 is consistent with the transportation direction of the electric flatbed trolley 7. Since the rotary storage platform 2.4 can complete the horizontal 90° rotation of several ingots 4 in one rotation, compared with the previous method of using an overhead crane to lift a single ingot 4 and complete the 90° rotation in the air, its efficiency and operational safety are greatly improved. After the rotary storage platform 2.4 completes the horizontal 90° rotation of the ingot 4, the overhead crane 3 does not need to perform another 90° rotation in the air after lifting the ingot 4. It can directly move to the upper part of the electric flatbed trolley 7, and then place the ingot 4 on the electric flatbed trolley 7, which will then transport the ingot 4 to the rolling processing workshop.

[0056] The parts of this invention not described in detail are prior art.
