Description

Technical Field

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

[0002] The existing 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 and ending casting stages. Before the subsequent rolling process, the head and tail parts of the ingots need to be sawed off by a sawing machine, and the ingots after sawing are then rolled to produce copper and copper alloy plates and strips.

[0003] At present, the design production scale of copper and copper alloy strip production enterprises is usually 30,000-100,000 tons / year, and the annual ingot casting demand is 40,000-150,000 tons / year. The output of conventional melting and casting units is 20,000-40,000 tons / year. The length of a single melting and casting unit is 9-18 meters. The equipment area of ​​the entire melting and casting workshop is conventionally about 100-120 meters long. According to the conventional configuration of the melting and casting unit, each copper and copper alloy strip production enterprise is generally equipped with an ingot sawing production line in the melting and casting workshop. At present, one ingot sawing production line is equipped with a sawing machine, and the maximum sawing processing capacity is 200,000 tons / year; the structure of the existing ingot sawing production line includes a loading and storage mechanism, a loading roller, a main saw head, a unloading roller and a unloading storage mechanism, etc. The length from the feeding mechanism to the unloading storage mechanism is 24-30m. Considering the ingot storage area before and after sawing, the reasonable length of a single sawing machine is about 60m. Therefore, the sawing production line is parallel to several melting and casting units arranged in parallel, and the ingots after sawing are perpendicular to the transportation direction; in order to reduce the lifting and transportation distance of the ingots, the general ingot sawing production line is arranged in parallel on the opposite side of the same span melting and casting unit, biased towards the ingot outflow direction of the ingot logistics transportation; the ingot sawing production line adopts a single-shift or two-shift work system. After a certain number of ingots of the same specification are produced, the enterprise flexibly chooses the off-peak electricity price period for sawing operations to save electricity costs, and at the same time facilitates the recovery of the material heads and sawdust of ingots of the same specification after sawing.

[0004] However, in recent years, the proportion of high-copper alloy, bronze alloy and nickel silver alloy ingots produced by enterprises has been increasing. Due to the slow sawing speed of high-copper alloy, bronze alloy and nickel silver alloy ingots (generally, the sawing speed of ordinary brass ingots is about 200mm / min, the sawing speed of ordinary copper ingots is about 150mm / min, and the sawing speed of high-copper alloy, bronze alloy and nickel silver alloy ingots is about 60mm / min, or even lower), the load of the ingot sawing production line increases for a period of time, exceeding the load of a single ingot sawing production line, and even three-shift continuous production still cannot meet the requirements. Therefore, it is necessary to increase the ingot sawing production line; but since the layout of the copper and copper alloy melting and casting operation area is generally compact, if two ingot sawing production lines are configured, whether the two ingot sawing production lines are set in series or in parallel, the floor space will be greatly increased. In addition, the addition of the second ingot sawing production line will lead to a significant increase in the investment in the company's new project; in addition, considering the logistics direction of the entire workshop, when the remote melting and casting unit lifts the ingot to the second ingot sawing production line, it needs to cross the first ingot sawing production line, which greatly increases the safety risk of the ingot lifting process.

[0005] In addition, the ingot sawing production lines currently in widespread use all adopt a horizontal loading method. The copper and copper alloy ingots are hoisted horizontally to the loading table of the sawing machine by a crane with a lifting clamp. The ingots on the loading table are sent to the loading roller of the sawing machine in a step-by-step manner, and then sent to the sawing machine for sawing operation through the loading roller. The existing copper and copper alloy ingots are finally hoisted horizontally from the vertical state to the loading device. The specific process 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 out of the casting pit, and then moves the overhead crane to lift the ingot to the 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, and the ingot is slowly tilted, and finally the ingot is horizontally placed in the temporary storage area for rough ingots. The flattened ingot is then lifted to the loading table of the ingot sawing machine by the lifting clamp;

[0006] 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, since 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 entire ingot lifting process; once an ingot falls, it may damage the walls, columns and surrounding equipment of the factory, and even cause casualties; 2. When the ingot is stored horizontally in the temporary storage area for raw ingots, in order to avoid the ingot occupying too long a space, the horizontally stored ingot is usually perpendicular to the ingot sawing production line. Therefore, when lifting the horizontal ingot to the loading platform, the ingot needs to be lifted in the air. Rotating 90°, 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, which leads to high risk, difficulty, and low efficiency in the lifting operation. 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. 3. After the ingot is sawed and processed, it is lifted and transported to an electric flatbed truck for transportation. Since the length direction of the ingot is perpendicular to the transportation direction of the electric flatbed truck, there is also the problem of lifting the ingot and rotating it 90° in the air. It can be seen from the above that the existing copper and copper alloy ingots are high in risk, low in lifting efficiency, and affect the normal work of other personnel and vehicles during the sawing and lifting process.

[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 deficiencies in the background technology, the utility model discloses a double-head sawing production line for copper and copper alloy ingots, which is provided with two sawing machines, and an intermediate roller table is arranged between the two sawing machines; a storage table and an ingot turning machine are symmetrically arranged on the outside of the two sawing machines in sequence, a storage pit is arranged on the outside of the adjacent ingot turning machines, 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, and the ingot turning machine turns the vertical ingots into a horizontal state, eliminating the previous operation of lifting the ingots by a crane and placing them flat in a temporary storage area for rough ingots, and the operation of lifting the ingots and rotating them 90 degrees in the air; the double-head sawing production line for copper and copper alloy ingots is vertically arranged with a plurality of melting and casting units arranged in parallel, so that the length direction of the ingots after processing is consistent with the transportation direction, and there is no need to use a crane to lift the ingots and rotate them 90 degrees in the air, which has the advantages of high processing efficiency, ingot lifting operation efficiency and safety, and reduces the investment cost at the same time.

[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 double-head sawing production line, which is arranged in an ingot melting and casting workshop, and is used for the head and tail sawing processing of copper and copper alloy ingots after casting; an overhead crane and a plurality of melting and casting units arranged in parallel are arranged in the ingot melting and casting workshop; an ingot rolling processing workshop is arranged adjacent to the ingot melting and casting workshop, and an electric flatbed car that reciprocates along the track is arranged between the ingot melting and casting workshop and the ingot rolling processing workshop; the ingots processed by the copper and copper alloy ingot double-head sawing production line are transported to the ingot rolling processing workshop by the electric flatbed car;

[0010] The copper and copper alloy ingot double-head sawing production line is equipped with two sawing machines, and an intermediate roller is arranged between the two sawing machines, and the intermediate roller is used to carry the head or tail of the ingot after sawing processing; storage tables and ingot turning machines are symmetrically arranged on the outside of the two sawing machines; the copper and copper alloy ingot double-head sawing production line is vertically arranged with several melting and casting units arranged in parallel; when the copper and copper alloy ingot double-head sawing production line is in production, the ingot turning machine on one side 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 turn the vertical ingot into a horizontal state, thereby eliminating the previous operation of lifting the ingot by the overhead crane and placing it flat in the temporary storage area for the rough ingot, greatly reducing the danger of the ingot lifting operation, and at the same time improving the lifting operation efficiency; the horizontal ingot is transported via the storage table At the first sawing machine, the head of the ingot is first sawed and then moved to the second sawing machine for sawing the tail of the ingot. At the same time, the second ingot is transported to the first sawing machine for sawing the head of the ingot. Therefore, the double-head sawing production line for copper and copper alloy ingots can saw two ingots at the same time, which greatly improves the sawing efficiency. Since the double-head sawing production line for copper and copper alloy ingots is vertically arranged with several melting and casting units arranged in parallel, the length direction of the ingots temporarily stored on the storage table on the other side after the sawing process is completed is consistent with the transportation direction of the electric flatbed truck. When the ingot is hoisted onto the electric flatbed truck, there is no need to use an overhead crane to lift the ingot and rotate it 90° in the air, which greatly improves the efficiency of ingot hoisting and reduces the danger of hoisting.

[0011] Furthermore, a storage pit is arranged on the side of the adjacent ingot turning machine. Since the length of the 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 life safety of the surrounding staff or damage the 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 arranged 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 life safety of the surrounding staff or damage the surrounding equipment; the ingot turning machine is hinged on the step surface on the side of the storage pit through a hinged seat arranged 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.

[0012] 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.

[0013] 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.

[0014] Furthermore, the ingots are stored in a vertical state on the storage rack. Because the storage rack is arranged in the storage pit, the center of gravity height of the ingots placed on the storage rack is greatly reduced. Even if the ingot falls over, the ingot will lean against the edge of the storage pit, so it will not endanger the life safety of surrounding workers or damage surrounding equipment. The production efficiency of the double-head sawing production line for copper and copper alloy ingots is much higher than that of the melting and casting unit. The ingots can be temporarily stored for a period of time before sawing. After a batch of copper or copper alloy ingots with the same specifications are all cast, the sawing operation is carried out at one time. The company's production arrangement can still adopt a single-shift or double-shift system, and the company can flexibly choose the off-peak electricity price period for sawing operations to save electricity costs. After the storage racks set in the storage pit are used to store the ingots in a vertical state, compared with the previous horizontal placement of the ingots in the temporary storage area for rough ingots, the length space occupied by the temporary storage of the ingots is greatly reduced, so that the area utilization rate of the production workshop is improved, and the production cost of the company is indirectly reduced.

[0015] Furthermore, the material storage table is fixedly arranged between the ingot turning machine and the sawing machine.

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

[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; in the later When the ingot after the sawing is completed moves to 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 between adjacent ingots, and the measurement value output by the draw rope sensor, thereby controlling the storage position of the ingot on the storage roller and automatically ensuring the spacing between adjacent ingots; in addition, the measurement value output by the draw rope sensor is also used to monitor the extreme 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 extreme movement distance of the drive block assembly and the limit switch for detecting the position of each ingot, greatly reducing the number of sensors on the sawing production line; the combination 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] 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 double-head sawing production line, which is provided with two sawing machines, and an intermediate roller is provided between the two sawing machines; a storage table and an ingot turning machine are symmetrically provided on the outside of the two sawing machines in sequence, a storage pit is provided on the outside of the adjacent ingot turning machine, and a storage rack is provided in the storage pit, and the ingots are temporarily stored on the storage rack in a vertical state; the copper and copper alloy ingot double-head sawing production line is vertically arranged with a plurality of melting and casting units arranged in parallel;

[0021] The setting of the storage rack changes the temporary storage of the existing ingots before processing from horizontal to vertical, which greatly shortens the length of the ingot sawing production line. After two sawing machines are set in one ingot sawing production line, the sawing production line is still kept short, so that the sawing production line can be set vertically to the melting and casting unit, and the production efficiency of the ingot sawing production line is greatly improved; the setting of the ingot turning machine changes the existing horizontal hanging of the ingots on the ingot sawing production line to a vertical mode, eliminating the previous operation of lifting the ingots by the overhead crane and placing them flat in the temporary storage area for the rough ingots, which greatly reduces the ingot lifting operation The danger of being cut by a crane is reduced, and the efficiency of hoisting operation is improved. In addition, the copper and copper alloy ingot double-head sawing production line is vertically arranged with several melting and casting units arranged in parallel, so that the length direction of the ingot after sawing is consistent with the transportation direction of the electric flatbed truck. Therefore, when the ingot after sawing is hoisted onto the electric flatbed truck, there is no need to use a crane to complete the 90° operation in the air. The copper and copper alloy ingot double-head sawing production line can greatly reduce the investment cost of new projects of enterprises, and at the same time greatly improve the efficiency and safety of ingot hoisting operation, so that the economic benefits of copper and copper alloy plate and strip production enterprises can be improved.

Before the production of the sawing production line, the drive block assembly 2.4.5.3 is moved to be flush with the travel switch 2.4.4.2, and then the measurement value output by the pull rope sensor 2.4.4.3 to the control system is reset to zero, and the zero point calibration of the pull rope sensor 2.4.4.3 is completed;

[0045] See the instruction manual Fig.13 , 14, 15: The driving block assembly 2.4.5.3 includes a driving block 2.4.5.3.1 and a driving claw 2.4.5.3.2. A driving claw groove is provided in the middle of the driving block 2.4.5.3.1. The driving claw 2.4.5.3.2 is hingedly arranged in the driving claw groove of the driving block 2.4.5.3.1 through a driving claw pin shaft 2.4.5.3.4; the driving block 2.4.5.3.1 is connected to the chain 2.4.5.4 through two sprocket pin shafts 2.4.5.3.3, wherein the sprocket pin shafts of adjacent driving claw pin shafts 2.4.5.3.4 are connected to the chain 2.4.5.4. A torsion spring 2.4.5.3.5 is also provided on the shaft 2.4.5.3.3, and the two torsion arms of the torsion spring 2.4.5.3.5 are in conflict with the driving block 2.4.5.3.1 and the driving claw 2.4.5.3.2 respectively; under normal conditions, the driving claw 2.4.5.3.2 is lifted up under the action of the torsion arms of the torsion spring 2.4.5.3.5, and when the driving block assembly 2.4.5.3 moves away from the baffle plate assembly 2.4.4 and encounters the ingot 4, it will be pressed down by the ingot 4 and contracted in the driving claw groove of the driving block 2.4.5.3.1.

[0046] After the melting and casting unit 1 completes the casting of the ingot 4, the overhead crane 3 hangs the head of the ingot 4 through the lifting clamp, and lifts 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 horizontally moved to the upper part of the storage pit 5 on one side of the copper and copper alloy ingot double-head sawing production line, 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 conflicts with 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;

[0047] After all the ingots 4 of the same specification have been cast, the sawing operation begins: first, the ingot turning machine 2.1 on one side of the copper and copper alloy ingot double-head sawing production line is turned over to a vertical state; the overhead crane 3 hangs the head of the ingot 4 stored on the storage rack 2.5 on the same side through the lifting clamp, rises and separates from the storage rack 2.5, and moves horizontally to the upper part of the ingot turning machine 2.1 on the same side, 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 middle part of the ingot 4 leans against the feed 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 to clamp the ingot 4 to prevent the ingot 4 from tipping sideways along the axial direction of the feed roller 2.1.4 during the turning process; the drive shaft of the ingot turning machine driving cylinder 2.1.3 contracts to drive the ingot turning machine 2.1 to turn over. Turn it to a horizontal state, make the roller surface of the ingot turning machine 2.1 flush with the roller surface of the feeding roller 2.4.2, release the ingot clamping claw 2.1.5, the feeding rollers of the ingot turning machine 2.1 and the feeding roller 2.4.2 rotate synchronously, the ingot 4 first moves to the feeding roller 2.4.2, and then drives into the first sawing machine 2.3 through the feeding roller 2.4.2 to saw the head of the ingot. The ingot 4 with the head cut off moves on the feeding roller 2.4.2 and the middle roller 2.6, and then enters the second sawing machine 2.3 to saw the tail of the ingot 4; when the tail of the first ingot 4 is sawed, the second ingot 4 enters the first sawing machine 2.3, and the head of the second ingot 4 is sawed at the same time; the above processing sequence is circulated until all the ingots 4 temporarily stored on the storage rack 2.5 are processed;

[0048] When the first ingot 4 is processed, it enters the feeding roller 2.4.2 of the storage platform 2.4 on the other side. At this time, the ingot driving system 2.4.5 of the storage platform 2.4 on this side is started; the driving block assembly 2.4.5.3 returns to its original position first: the driving motor on the driving sprocket assembly A2.4.5.1 rotates counterclockwise, the driving sprocket rotates counterclockwise, and the sprocket drives the chain 2.4.5.4 to rotate, driving the driving block assembly 2.4.5.3 to move to the outside of the feeding roller 2.4.2 first (after the driving block assembly 2.4.5.3 moves from the ingot to the outside of the feeding roller 2.4.2). When the lower part of the ingot 4 passes through, the driving claw 2.4.5.3.2 automatically shrinks 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 in real time 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, and the driving sprocket rotates clockwise. The sprocket drives the chain 2.4.5.4 to rotate, driving the driving block assembly 2.4.5.3 to move toward the baffle 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 on the feeding roller 2.4.2 to transfer to the storage roller 2.4.3, and moves along the storage roller 2.4.3 toward the baffle assembly 2.4.4. When the ingot 4 moves toward the baffle assembly 2.4.4, the rope of the traction rope sensor 2.4.4.3 is pulled. The rope sensor 2.4.4.3 measures the moving position of the driving block assembly 2.4.5.3 in real time; 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 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;

[0049] 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;

[0050] When the second ingot 4 has completed sawing, the second ingot 4 enters the feeding 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 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;

[0051] Repeat the above-mentioned movement control process of the second ingot 4 until all n ingots 4 are moved into place; when all ingots 4 are processed, the overhead crane 3 uses a lifting clamp to lift the ingot 4 temporarily stored on the storage platform 2.4 and directly translates it to the upper part of the electric flatbed truck 6, and then drops the ingot 4 onto the electric flatbed truck 6, which transports the ingot 4 to the rolling processing workshop.
