Description

Technical Field

[0001] This invention relates to the field of copper and copper alloy ingot sawing technology, specifically to an automatic ingot-turning double-head 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, which produces copper and copper alloy ingots in a vertical state. Due to the poor quality of the ingots formed during the initial and final casting stages, the ingots produced by this process need to be sawed off by a sawing machine before subsequent rolling processing. The sawed ingots are then rolled to produce copper and copper alloy plates and strips.

[0003] Currently, the designed production scale of copper and copper alloy plate and strip manufacturers is typically 30,000-100,000 tons / year, requiring 40,000-150,000 tons / year of ingot casting. The output of a conventional casting unit is 20,000-40,000 tons / year. A single casting unit occupies a length of 9-18 meters, and the entire casting workshop's equipment area typically occupies approximately 100-120 meters. Based on the standard configuration of the casting units, each copper and copper alloy plate and strip manufacturer's casting workshop is generally equipped with one ingot sawing production line. Currently, each ingot sawing production line is equipped with one sawing machine, with a maximum sawing capacity of 200,000 tons / year. The existing ingot sawing production line structure includes a feeding and storage mechanism, a feeding roller conveyor, a main saw head, a discharging roller conveyor, and a discharging and storage mechanism. The length from the material feeding mechanism to the unloading and storage mechanism is 24-30m. Considering the storage area for ingots before and after sawing, the reasonable footprint of a single sawing machine is about 60m. Therefore, the sawing production line is set up in parallel with several melting and casting units, and the sawn ingots are perpendicular to the transportation direction. To reduce the distance of ingot hoisting and transportation, the ingot sawing production line is generally arranged in parallel on the opposite side of the melting and casting unit in the same span, biased towards the ingot delivery direction of the ingot logistics transportation. The ingot sawing production line adopts a single-shift or two-shift work system. After producing a certain number of ingots of the same specification, the enterprise flexibly chooses to carry out sawing operations during off-peak electricity price periods to save electricity costs, and at the same time facilitates the recycling of the material heads and sawdust of ingots of the same specification after sawing.

[0004] However, in recent years, enterprises have been producing a larger proportion of high-copper alloy, bronze alloy, and cupronickel alloy ingots. Because the sawing speed for these ingots is relatively slow (generally, the sawing speed for ordinary brass ingots is about 200 mm / min, for ordinary copper ingots it's about 150 mm / min, and for high-copper alloy, bronze alloy, and cupronickel alloy ingots it's about 60 mm / min, or even lower), the load on the ingot sawing production line increases for a certain period, exceeding the capacity of a single production line. Even three shifts of continuous production cannot meet the requirements. Therefore, it is necessary to add an ingot sawing production line; however, since the layout of copper and copper alloy smelting and casting operation areas is generally quite compact, if two ingot sawing production lines are configured, whether the two ingot sawing production lines are set up in series or in parallel, the footprint will be greatly increased. In addition, the addition of a second ingot sawing production line will lead to a significant increase in the investment amount of the company's new project. Furthermore, considering the logistics direction of the entire workshop, when the remote smelting and casting unit lifts ingots to the second ingot sawing production line, it is necessary to cross the first ingot sawing production line, which greatly increases the safety risks in the ingot lifting process.

[0005] In addition, most widely used ingot sawing production lines currently employ a horizontal feeding method. Copper and copper alloy ingots are initially lifted vertically (after casting, the ingots are in a vertical position) by a crane using clamps, and finally transported horizontally to the feeding platform of the sawing machine. The ingots on the feeding platform are then fed onto the feeding roller conveyor of the sawing machine via a stepping motion, and finally fed into the sawing machine for sawing operations. Currently, copper and copper alloy ingots are ultimately lifted horizontally from a vertical position to the feeding device. The specific process is as follows: First, the overhead crane 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 is then moved to transport 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 horizontally in the temporary storage area for raw ingots. The flattened ingot is then lifted by the clamp to the loading platform of the ingot sawing machine.

[0006] 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 stage of the entire hoisting process. If an ingot falls, it may damage factory walls, pillars, and surrounding equipment, and 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 the horizontal ingots to the loading platform, they need to be suspended in the air. Rotating the ingot 90° in the air requires a large operating space and slow rotation to prevent excessive rotational inertia. Simultaneously, the distance between the ingot and factory walls, columns, and equipment must be estimated, resulting in high risk, difficulty, and low efficiency in the hoisting operation. In particular, no personnel or vehicles are allowed on the ground during the hoisting and rotation process, thus affecting the normal work of other personnel and vehicles. 3. After sawing, when the ingot is hoisted onto an electric flatbed truck for transport, the length direction of the ingot is perpendicular to the transport direction of the electric flatbed truck, thus requiring the ingot to be lifted and rotated 90° in the air. Therefore, it is clear that existing methods for hoisting copper and copper alloy ingots during sawing and processing present problems of high risk, low efficiency, and disruption to the normal work of other personnel and vehicles.

[0007] The aforementioned problems must be considered and addressed when constructing new copper and copper alloy sheet and strip production projects. However, existing ingot sawing production lines are structurally limited and cannot meet the requirements for solving these problems, thus requiring improvement. Summary of the Invention

[0008] To overcome the shortcomings of the prior art, this invention discloses an automatic ingot-turning double-head sawing production line, which is equipped with two sawing machines and an intermediate roller conveyor between them. One sawing machine has a feeding roller conveyor and an ingot-turning machine arranged sequentially on its outer side, while the other sawing machine has a storage platform on its outer side. Storage pits are located on the outer side of adjacent ingot-turning machines, and storage racks are installed within these pits. Ingots are temporarily stored vertically on the storage racks, reducing the length space occupied by horizontally placed ingots. The ingot-turning machine flips the vertically positioned ingots to a horizontal position, eliminating the need for overhead cranes to lift ingots and place them flat in the temporary ingot storage area, and for lifting ingots and rotating them 90° in the air. The automatic ingot-turning double-head sawing production line is vertically arranged with several parallel casting and melting units, ensuring that the length direction of the processed ingots is aligned with the transport direction, eliminating the need for overhead cranes to lift ingots and rotate them 90° in the air. This automatic ingot-turning double-head sawing production line has advantages in processing efficiency, ingot lifting efficiency, and safety, while also reducing investment costs.

[0009] To achieve the aforementioned objective, the present invention employs the following technical solution: an automatic ingot-turning double-head sawing production line, set up within an ingot casting workshop, is used for head and tail sawing processing of copper and copper alloy ingots after casting is completed; the ingot casting workshop is equipped with an overhead crane and several casting units arranged in parallel; an ingot rolling processing workshop is adjacent to the ingot casting workshop, and an electric flatbed cart that moves back and forth along a track is provided between the ingot casting workshop and the ingot rolling processing workshop; the ingots processed by the automatic ingot-turning double-head sawing production line are transported to the ingot rolling processing workshop by the electric flatbed cart;

[0010] The automatic ingot-turning double-head sawing production line is equipped with two sawing machines, with an intermediate roller conveyor (existing technology) between them to support the head or tail of the ingot after sawing. One sawing machine has a feeding roller conveyor (existing technology) and an ingot-turning machine arranged sequentially on its outer side, while the other sawing machine has a storage platform on its outer side. The feeding roller conveyor is used to move the ingot to the sawing machine. The automatic ingot-turning double-head sawing production line is vertically arranged with several parallel casting and melting units, with the ingot-turning machine located closer to the casting and melting units. During operation, the ingot-turning machine is in an upright position. An overhead crane vertically lifts the ingot onto the upright ingot-turning machine, which then flips it, transforming the vertical ingot into a horizontal position. This eliminates the previous operation of lifting the ingot by overhead crane and placing it flat in the temporary ingot storage area, greatly reducing the danger of ingot handling. This reduces the risk of accidents while improving the efficiency of hoisting operations. Horizontally positioned ingots are conveyed via a feeding roller conveyor to the first sawing machine, where the head of the ingot is first sawed. Then, the ingot is moved to the second sawing machine for tail sawing. Simultaneously, a second ingot is conveyed to the first sawing machine for head sawing. Therefore, the automatic ingot-turning double-head sawing production line can simultaneously saw two ingots, greatly improving sawing efficiency. Since the automatic ingot-turning double-head sawing production line is vertically arranged with several parallel casting and melting units, the length of the ingots temporarily stored on the storage platform after sawing is aligned with the transport direction of the electric flatbed truck. When hoisting the ingots onto the electric flatbed truck, there is no need to use an overhead crane to rotate the ingots 90° in the air, greatly improving the efficiency of ingot hoisting operations and reducing the risks associated with hoisting.

[0011] Furthermore, a storage pit is provided on the side of the adjacent ingot tilting machine. The ingot tilting machine is hinged to the stepped surface on the side of the storage pit via a hinge seat set on the ingot tilting machine base. When the ingot tilting machine tilts, it rotates around the hinge axis, changing from a vertical state to a horizontal state, or from a horizontal state to a vertical state. 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 also be too large. After setting the storage pit on the side of the ingot tilting machine, the lower end of the ingot tilting machine will be located in the storage pit when it is in a vertical state. Therefore, the center of gravity of the ingot placed on the tilting machine is greatly reduced. Even if the ingot tilts, the ingot will lean against the edge of the storage pit, so it will not endanger the lives of nearby workers or damage the surrounding equipment.

[0012] 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.

[0013] Furthermore, the ingot flipping machine is hinged with ingot-clamping claws driven by an ingot-clamping claw drive cylinder. After the ingot falls onto the ingot flipping machine in a vertical state, the ingot-clamping claws are driven by the ingot-clamping claw drive cylinder to rotate and clamp the ingot, preventing the ingot from tilting to the side during the flipping process.

[0014] Furthermore, the ingots are stored vertically on the storage 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 automatic ingot-turning double-head sawing production line is much higher than that of the melting and casting unit. Ingots can be temporarily stored for a period of time before sawing. After all copper or copper alloy ingots of the same specifications have been cast, the sawing operation is carried out at once. Therefore, the company can still adopt a single-shift or double-shift production schedule. The company can flexibly choose to carry out sawing operations during off-peak electricity price periods to save on electricity costs. After using the storage racks set in the storage pit to store the ingots vertically, compared with the previous horizontal placement of ingots in the temporary ingot storage area, the length space occupied by the temporary storage of ingots is greatly reduced, which improves the utilization rate of the production workshop area and indirectly reduces the company's production costs.

[0015] Furthermore, the storage platform includes a storage platform base, receiving roller conveyor, storage roller conveyor, baffle plate assembly, and ingot driving system; the receiving roller conveyor, storage roller conveyor, baffle plate assembly, and ingot driving system are fixedly mounted on the upper part of the storage platform base via a support plate; the sawn ingots first enter the receiving roller conveyor of the storage platform, and then are driven by the ingot driving system to enter the storage roller conveyor for temporary storage; the structure in which the receiving roller conveyor and storage roller conveyor are jointly mounted on the storage platform base can further shorten the length of the automatic ingot flipping double-head sawing production line.

[0016] 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 ingot after sawing 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. When the ingots after sawing are 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, greatly 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.

[0017] 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.

[0018] Furthermore, a drive claw is hinged to the drive block assembly, and the drive claw drives the processed ingot to move on the storage roller conveyor in one direction.

[0019] Due to the adoption of the above-described technical solution, the present invention has the following beneficial effects: The automatic ingot-turning double-head sawing production line disclosed in the present invention is equipped with two sawing machines, and an intermediate roller conveyor is provided between the two sawing machines; a feeding roller conveyor (existing technology) and an ingot-turning machine are sequentially arranged on the outside of one sawing machine, and a storage platform is provided on the outside of the other sawing machine. A storage pit is provided on the outside of the adjacent ingot-turning machine, and a storage rack is provided in the storage pit. The ingots are temporarily stored on the storage rack in a vertical state; the automatic ingot-turning double-head sawing production line is arranged perpendicularly to several parallel melting and casting units, with the ingot-turning machine close to the melting and casting unit side;

[0020] The installation of storage racks changes the existing temporary storage of ingots before processing from a horizontal to a vertical method, greatly shortening the length of the ingot sawing production line. Even with two sawing machines in one production line, the line remains relatively short, allowing it to be installed perpendicular to the melting and casting unit. This also significantly improves the production efficiency of the ingot sawing production line. The installation of the ingot turning machine changes the existing method of horizontally suspending ingots on the ingot sawing production line to a vertical method, eliminating the need for overhead cranes to lift ingots and place them flat in the temporary ingot storage area, greatly reducing the cost of casting. This automatic ingot-turning double-head sawing production line reduces the dangers of ingot hoisting operations while improving efficiency. Furthermore, the vertical arrangement of the automatic ingot-turning double-head sawing production line with several parallel casting units ensures that the length of the sawed ingots aligns with the transport direction of the electric flatbed truck. Therefore, when hoisting the sawed ingots onto the electric flatbed truck, there is no need for an overhead crane to perform a 90° rotation in the air. This automatic ingot-turning double-head sawing production line can significantly reduce the investment costs of new projects for enterprises, while greatly improving the efficiency and safety of ingot hoisting operations, thereby enhancing the economic benefits for copper and copper alloy plate and strip production enterprises.

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.

[0043] See the instruction manual appendix Figure 12 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.

[0044] See the instruction manual appendix Figure 13 , 1415: Drive block assembly 2.4.5.3 includes drive block 2.4.5.3.1 and drive claw 2.4.5.3.2. Drive block 2.4.5.3.1 has a drive claw groove in the middle. Drive claw 2.4.5.3.2 is hinged in the drive claw groove of drive block 2.4.5.3.1 through drive claw pin 2.4.5.3.4. Drive block 2.4.5.3.1 is connected to 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.

[0045] After casting unit 1 completes the casting of ingot 4, overhead crane 3 uses clamps to lift the head of 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 of the automatic ingot flipping double-head sawing production line and slowly lowered into storage rack 2.5. The tail of ingot 4 is stuck 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 ingot 4 from sliding. The middle of ingot 4 is stuck 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 ingot 4 from tipping over. Ingot 4 is temporarily stored in storage rack 2.5.

[0046] After all ingots 4 of the same specification have been cast, the sawing operation begins: First, the ingot flipper 2.1 of the automatic ingot flipping double-head sawing production line is flipped to a vertical position; the overhead crane 3 lifts the head of the ingot 4 stored on the same-side storage rack 2.5 with clamps, rises away from the storage rack 2.5, moves horizontally to the upper part of the ingot flipper 2.1 on the same side, 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 to prevent the ingot 4 from tilting laterally along the axial direction of the feeding roller 2.1.4 during the flipping process; the drive shaft of the ingot flipper driving cylinder 2.1.3 retracts, driving the ingot flipper 2. 1. Flip the ingot 4 to a horizontal position, making the roller surface of the ingot flipping machine 2.1 flush with the roller surface of the feeding roller 2.2. Release the ingot clamping claw 2.1.5. The feeding rollers of the ingot flipping 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 first sawing machine 2.3 to saw off the head of the ingot. The ingot 4 with its head cut off moves on the feeding roller 2.2 and the intermediate roller 2.6, and then enters the second sawing machine 2.3 to saw off the tail of the ingot 4. While sawing off the tail of the first ingot 4, the second ingot 4 enters the first sawing machine 2.3, and the head of the second ingot 4 is sawn off at the same time. The above processing sequence is repeated until all the ingots 4 temporarily stored on the storage rack 2.5 are processed.

[0047] After the first ingot 4 is processed, it enters the receiving roller conveyor 2.4.2 of the storage platform 2.4. At this time, the ingot drive system 2.4.5 of the storage platform 2.4 on this side is started; 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, and drives the drive block assembly 2.4.5.3 to move to the outside of the receiving roller conveyor 2.4.2 (where the drive block assembly 2.4.5.3 moves from the ingot 4). When the lower part passes through, the drive claw 2.4.5.3.2 automatically retracts into the drive claw groove of the drive block 2.4.5.3.1. 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 in real time to prevent it from moving out of bounds. 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, and the drive sprocket rotates clockwise. The sprocket drives the chain 2.4.5.4 to rotate, causing the drive block assembly 2.4.5.3 to move towards the baffle plate assembly 2.4.4. At this time, the drive pawl 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 then 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 traction rope sensor 2.4.4.3 retracts its rope. The short-range pull rope sensor 2.4.4.3 measures the moving position of the drive block assembly 2.4.5.3 in real time; 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 placement position of the first ingot 4 on the storage roller conveyor 2.4.3.

[0048] 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.

[0049] 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.

[0050] Repeat the above-mentioned movement control process for the second ingot 4 until all n ingots 4 are moved into place; after all ingots 4 are processed, the overhead crane 3 lifts the ingots 4 temporarily stored on the storage platform 2.4 with a clamp and moves them directly to the upper part of the electric flatbed trolley 6, and then the ingots 4 are placed on the electric flatbed trolley 6, which transports the ingots 4 to the rolling processing workshop.

[0051] This automatic ingot-turning double-head sawing production line is suitable for new copper and copper alloy plate and strip production projects.
