Description

Technical Field

[0001] This invention relates to the field of scrap steel processing technology, and in particular to a cutting and processing production line for scrap steel tail coils. Background Technology

[0002] On production lines that cold-roll hot-rolled steel coils, some of the core material of the hot-rolled coils does not meet the requirements for cold rolling and is therefore cut off as scrap steel tail coils. Other production lines also produce similar scrap steel tail coils. These scrap steel tail coils may be longer than the maximum scrap steel length specified by the steelmaking furnace and must be processed into smaller scrap steel pieces before being fed into the furnace.

[0003] However, scrap steel tail coils differ from other types of scrap steel and cannot be processed using simple cutting methods. For example, they cannot be cut along their axis, otherwise they will not only scatter into stacked steel plates that cannot be further cut, but also cause a safety accident at the moment of final release. Therefore, there is an urgent need to provide a safe and reliable scrap steel tail coil cutting and processing production line to safely, reliably, and quickly cut excessively long scrap steel tail coils to the appropriate length. Summary of the Invention

[0004] This invention provides a cutting and processing production line for scrap steel tail coils, in order to solve the technical problem of urgently needing a safe and reliable cutting and processing production line for scrap steel tail coils, so as to safely, reliably and quickly cut excessively long scrap steel tail coils into suitable lengths.

The process involves pressing; a cutting device, located at the cutting station, cuts the pressed scrap steel coils to obtain at least two smaller scrap steel coils; a flattening device, located at the flattening station, flattens each of the obtained smaller scrap steel coils to obtain finished scrap steel products; and a transfer device transfers the scrap steel coils to be cut from the scrap steel coil storage device to the packaging device, transfers the bundled scrap steel coils to the cutting device, and transfers the smaller scrap steel coils from the cutting device to the flattening device.

[0006] In one embodiment of the present invention, the clamping device includes an outer clamping roller and an inner clamping roller. The outer clamping roller is placed outside the scrap steel tail coil, and the inner clamping roller is placed inside the scrap steel tail coil. Under the action of the clamping mechanism, the outer clamping roller and the inner clamping roller clamp the interlayer strip steel of the tail coil and roll on the inner and outer surfaces of the scrap steel tail coil when the scrap steel tail coil rotates, so as to ensure the smooth progress of subsequent cutting.

The intelligent hydraulic system drive unit controls the upper hydraulic head to squeeze the scrap steel coil from above, causing the scrap steel coil to be in an upward concave state. Then, the intelligent hydraulic system drive unit controls the upper hydraulic head and the two side hydraulic heads to squeeze the upward concave scrap steel coil from above and from both sides until the scrap steel coil is M-shaped, thus completing the flattening process of the scrap steel coil and obtaining the finished scrap steel product.

[0011] In one embodiment of the present invention, the transfer device is an overhead crane and an object gripping unit that cooperates with the overhead crane.

[0012] In one embodiment of the present invention, the transfer device is a stepping trolley and an object gripping unit that cooperates with the stepping trolley.

[0014] In one embodiment of the present invention, the scrap steel tail coil cutting and processing production line further includes a machine vision unit and a determination unit; the machine vision unit is used to acquire a first image of the scrap steel tail coil to be cut and to acquire a second image of the bundled scrap steel tail coil to be cut; the determination unit is used to determine one or more bundling positions on the scrap steel tail coil to be cut based on the first image and a preset interval distance, and to determine one or more cutting points on the bundled scrap steel tail coil to be cut based on the second image and a preset cutting interval, and to send the bundling positions to the packaging device, and to send the cutting positions of the cutting points to the cutting device.

[0016] Figure 1 This is a schematic diagram of a cutting and processing production line for scrap steel tail coils provided in an embodiment of the present invention. Detailed Implementation

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of a cutting and processing production line for scrap steel tail coils provided in an embodiment of the present invention, for reference. Figure 1 The scrap steel tail coil cutting and processing production line 100 includes a preparation station, a baling station, a cutting station, and a flattening station arranged sequentially along the line. The scrap steel tail coil cutting and processing production line 100 includes: a scrap steel tail coil storage device 1, located at the preparation station, for temporarily storing scrap steel tail coils to be cut; a baling device 2, located at the baling station, for bundling the scrap steel tail coils to be cut using at least one baling strap; and a pressing device 3, located at the cutting station, for pressing the bundled scrap steel tail coils to be cut during the cutting process. It can ensure the smooth progress of flame cutting; the cutting device 4, located at the cutting station, is used to cut the scrap steel tail coils that are in a compressed state to obtain at least two small scrap steel coils; the flattening device 5, located at the flattening station, is used to flatten each obtained small scrap steel coil to obtain finished scrap steel; the transfer device 6 is used to transfer the scrap steel tail coils to be cut from the scrap steel tail coil storage device to the packaging device, transfer the bundled scrap steel tail coils to be cut from the packaging device to the cutting device, and transfer the small scrap steel coils from the cutting device to the flattening device.

[0021] In this technical solution, by sequentially arranging a scrap steel tail coil storage device at the preparation station, a packing device at the packing station, a cutting device at the cutting station, and a flattening device at the flattening station along the production line, the scrap steel tail coil cutting and processing production line can temporarily store, bundle, cut, and flatten the scrap steel tail coils in sequence. It can achieve automated, safe, and reliable scrap steel tail coil cutting and processing, safely cut excessively long scrap steel tail coils to appropriate lengths, avoid safety accidents, and realize rapid and safe processing and production of scrap steel tail coils.

[0022] As an example, each workstation is equipped with a corresponding support to support and store the corresponding scrap steel coils. The movement of the steel coils between the supports is achieved by overhead cranes, stepping trolleys, and other methods.

[0023] In practical applications, multiple production lines can reuse the same transfer device, provided that transportation efficiency is sufficient. For example, a transfer device can be set up between two production lines, saving production costs by reusing the device. Alternatively, two transfer devices can be set up between two production lines, allowing them to cross-transport related materials. This avoids production line downtime caused by the failure of any one of the transfer devices.

[0024] As an example, the clamping device can be set to ensure that the distance between the clamped strips is less than a preset gap threshold, which can be 1 / 10 of the strip thickness or other values ​​set by those skilled in the art. At the cutting station, the clamping device first clamps the strips and then cuts them; the entire cutting process remains in a clamped state. During the transfer process, as the transfer device moves the bundled scrap steel tail coils to the cutting device, the scrap steel tail coils to be cut are also placed between the outer and inner clamping rollers of the clamping device.

[0025] In one embodiment, the baling device includes an automated baling robot for baling multiple coils of scrap steel to be cut using one or more baling straps at preset intervals. The scrap steel coils to be cut are often required to be cut into multiple parts. The number of parts to be cut can be determined according to preset rules, and then the number of baling straps needed and the position of each baling strap can be determined based on the number of parts. The automated baling robot then ties the baling straps to the corresponding positions. The automated baling robot can automatically pick up the baling straps and tie them at appropriate positions. This automated baling robot can support the baling of multiple baling straps at once, or it can tie baling straps one by one.

[0026] In one embodiment, the clamping device includes an outer clamping roller and an inner clamping roller. The outer clamping roller is placed outside the scrap steel tail coil, and the inner clamping roller is placed inside the scrap steel tail coil. The outer and inner clamping rollers clamp the interlayer strip steel of the tail coil under the action of the clamping mechanism (such as a mechanical mechanism, hydraulic mechanism, pneumatic mechanism, etc.), and roll on the inner and outer surfaces of the scrap steel tail coil when the scrap steel tail coil rotates, so as to ensure the smooth progress of subsequent flame cutting.

[0027] In one embodiment, the scrap steel coil storage device is equipped with a coil storage support for holding the scrap steel coils to be cut. A weight sensor can also be installed on the coil storage support to weigh the scrap steel coils to be cut. Furthermore, a machine vision device can be installed in the scrap steel coil storage device to measure the initial length of the scrap steel coils to be cut, so as to facilitate subsequent calculation and planning of data such as the number of cuts.

[0028] In one embodiment, the cutting device includes: a cutting station support for placing the bundled scrap steel coil to be cut; a steel coil rotating unit for controlling the bundled scrap steel coil to be cut to rotate on the cutting station support at a preset speed; and a cutting robot for performing multiple cuts on the compressed scrap steel coil at a preset cutting interval. The preset speed can be a speed pre-set by those skilled in the art, or it can be determined by comprehensively evaluating data such as the flow rate of heated oxygen and the flow rate of heated gas in the following embodiments. The steel coil rotating unit allows the scrap steel coil to be cut to rotate automatically during flame cutting, eliminating the need for the cutting head of the flame cutting robot to move, thus improving the safety of the implementation.

[0029] As an example, the cutting station is equipped with an intelligent steel coil rotation system, which uses frequency conversion speed regulation technology and corresponding drive devices to enable the scrap steel tail coil to rotate at the speed required by the process on the support of the cutting station.

[0030] Following the above embodiments, the cutting robot is a flame cutting robot. The flame cutting robot includes a heating oxygen flow control unit, a heating gas flow control unit, and a slag blowing oxygen flow control unit. The heating oxygen flow control unit and the heating gas flow control unit control the flow rates of the heating oxygen and heating gas to control the heating temperature of the cutting points on the compressed scrap steel coil to be cut. The slag blowing oxygen flow control unit controls the flow rate of the slag blowing oxygen to control the cutting speed of the cutting points on the bundled scrap steel coil to be cut. Through these control units, the gas flow rate can be adjusted in a timely manner according to the cutting effect, balancing cutting efficiency and gas consumption, thereby balancing the contradiction between cutting results and costs.

[0031] Following the above embodiments, the cutting device further includes a temperature measuring unit to measure the current heating temperature at the cutting point. If the current heating temperature is higher than the preset target temperature, the slag blowing oxygen flow control unit is controlled to start releasing slag blowing oxygen. The temperature measuring unit enables temperature measurement of the heating point, allowing for timely cutting when the temperature reaches the target, further avoiding resource waste.

[0032] As an example, the cutting station is equipped with an automatic flame cutting robot capable of making multiple cuts at specified distances on scrap steel coils. The automatic flame cutting robot is equipped with an automatic flow control system for heating oxygen, heating gas, and slag-blowing oxygen, as well as corresponding equipment and instruments. The automatic flame cutting robot is also equipped with a cutting point temperature control system, which uses a high-temperature optical thermometer to detect the temperature at the cutting point and uses the automatic flow control system for heating oxygen, heating gas, and slag-blowing oxygen to control the heating power, thereby achieving intelligent control of the cutting point temperature. It is also equipped with an automatic cutting control system that coordinates the intelligent steel coil rotation control system with the intelligent cutting point temperature control system to achieve the goal of optimal cutting.

[0033] For example, during the cutting process, machine vision is used to identify and determine the midpoint between two adjacent strapping bands on the scrap steel coil to be processed, and this midpoint is designated as the cutting position. The cutting position is then heated using a flame torch. Once the temperature reaches the preset target temperature, flame cutting is performed at the position using the flame torch. During flame cutting, the scrap steel coil is rotated to create relative movement between it and the flame torch until the flame-cut kerf completes a full circle on the coil. When the flame-cut kerf completes a full circle on the coil, the cutting at that position is considered complete.

[0034] As an example, the preset target temperature can be determined by the material of the scrap steel coil to be processed. Different materials have different melting points. Then, a preset temperature (e.g., 100℃) is added to the melting point to obtain the preset target temperature.

[0035] In one embodiment, the flattening device includes an upper hydraulic head, a lower hydraulic head, and an intelligent hydraulic system drive unit. The intelligent hydraulic system drive unit controls the upper and lower hydraulic heads to flatten the scrap steel coils placed between them. The specific degree of flattening can be set by those skilled in the art as needed, and is not limited here.

[0036] As an example, the flattening station is equipped with upper and lower hydraulic heads, which are intelligently driven by a hydraulic system to flatten several small coils of scrap steel after cutting, according to process requirements.

[0037] In another embodiment, the flattening device includes an upper hydraulic head, two side hydraulic heads, and an intelligent hydraulic system drive unit. The intelligent hydraulic system drive unit controls the upper hydraulic head to squeeze the scrap steel coil from above, causing the scrap steel coil to be in an upward concave state. Then, the intelligent hydraulic system drive unit controls the upper hydraulic head and the two side hydraulic heads to squeeze the upward concave scrap steel coil from above and from both sides until the scrap steel coil is M-shaped, completing the flattening process of the scrap steel coil and obtaining the finished scrap steel product.

[0038] It is understandable that the small coil of scrap steel is supported from below, which can be achieved through one or more support components. Then, it is first compressed by an upper hydraulic head positioned above the coil (which may or may not be directly above the center). This creates a depression at the top of the coil. Then, the hydraulic heads at both ends of the coil, along with the upper hydraulic head, simultaneously compress it, ensuring the coil is stressed from both top and sides, resulting in an M-shape. This shape is merely an example and is not necessarily symmetrical, thus completing the flattening process. Since the scrap steel coil may be elastic, it will spring back after simple flattening. Therefore, this flattening method minimizes the risk of subsequent springback.

[0039] Since there are still certain safety hazards in the form of steel coils during transportation, they can be compressed using hydraulic tools to obtain finished scrap steel, thus avoiding the danger caused by the steel coils unraveling. The degree of flattening can be set by those skilled in the art as needed, and can be determined based on the weight, material, length, and other characteristics of the scrap steel coils.

[0040] In one embodiment, the transfer device is an overhead crane and an object gripping unit that works in conjunction with the overhead crane. For example, the overhead crane can be used to hoist and transfer relevant materials, thereby improving transportation efficiency.

[0041] In another embodiment, the transfer device is a stepping trolley (such as a stepper motor trolley) and an object gripping unit that cooperates with the stepping trolley. This allows the transfer of relevant materials to be achieved through the movement of the trolley.

[0042] In one embodiment, the transfer device is also used to transfer finished scrap steel from the flattening station to a storage warehouse. After the finished scrap steel is produced, it can be stored in the corresponding storage warehouse for later use.

[0043] In one embodiment, the scrap steel tail coil cutting and processing production line further includes a machine vision unit and a determination unit; the machine vision unit is used to acquire a first image of the scrap steel tail coil to be cut and to acquire a second image of the bundled scrap steel tail coil to be cut; the determination unit is used to determine one or more bundling positions on the scrap steel tail coil to be cut based on the first image and a preset interval distance, and to determine one or more cutting points on the bundled scrap steel tail coil to be cut based on the second image and a preset cutting interval, and to send the bundling positions to the packaging device, and to send the cutting positions of the cutting points to the cutting device.

[0044] The binding and cutting positions can be determined in advance according to certain positional rules. For example, one end of the scrap steel coil to be cut can be used as the starting point, and the distance along the length direction can be used as the position marker. This allows other machines to know the method of determining the relative coordinate system and complete the determination of the relevant positions.

[0045] Because scrap steel coils tend to unravel after cutting, they must be re-bundled before cutting to prevent the coils from falling apart. Therefore, it's necessary to pre-determine the required quantity and placement of the strapping, and to bundle the coils before cutting to ensure they remain intact after the process.

[0046] In one embodiment, the method for determining the number of bundling positions includes: if the initial length of the scrap steel coil to be cut is an integer multiple of the target processing length, the quotient of the initial length and the target processing length is determined as the number of bundling positions; if the initial length is not an integer multiple of the target processing length, the integer value of the quotient of the initial length and the target processing length is determined, and the new value obtained by adding 1 to the integer value is determined as the number of bundling positions. For example, if the initial length is 5 meters and the target processing length is 1 meter, then the number of bundling positions is 5; as another example, if the initial length is 5.1 meters and the target processing length is 1 meter, then the number of bundling positions is 6. The number of strapping tapes is the same as the number of bundling positions. As an example, the actual processing length can be recalculated based on the number of bundling positions (6) to replace the initial target processing length, and subsequent processing can then proceed.

[0047] In one embodiment, if the initial length is not an integer multiple of the target processing length, a first type of packing strap and one second type of packing strap are used to bundle the scrap steel coil to be processed. The second type of packing strap is positioned close to one end of the scrap steel coil to be processed. The second type of packing strap can be positioned close to any end as determined by those skilled in the art, and is not limited here.

[0048] The second type and the first type are different types of packing straps. They can be distinguished in at least one dimension, such as color, material, pattern, and width, so that those skilled in the art can differentiate them.

[0049] It's understandable that if the initial length of the scrap steel coil to be processed is an integer multiple of the target processing length, then the coil can be evenly divided and cut using normal methods. However, the initial length of the scrap steel coil to be processed is often not an integer multiple of the target processing length. This results in one small scrap steel coil being significantly smaller in weight and length than the others, which is detrimental to subsequent reuse and may lead to problems with the feeding ratio during subsequent material input due to a lack of consideration for the differences between the small scrap steel coils. To address this issue, the two situations can be distinguished during the planning of the baling straps. Then, a different type of baling strap can be used to bundle the scrap steel coils that are shorter than the target processing length to differentiate them.

[0050] As an example, the binding position can be determined by defining the binding position of a strap at intervals from the starting binding position and the target processing length. The starting binding position is defined as halfway between the starting and ending points of the target processing length from one end of the scrap steel coil to be processed. This method of determining the position further ensures that after subsequent cutting, the binding strap is located in the middle of the scrap steel coil.

[0051] Following the above embodiments, if at least one binding position of the strapping tape is the same as the original position of the original strapping tape of the scrap steel coil to be processed, or if the positional error between the original position of the original strapping tape of the scrap steel coil to be processed and the binding position of any strapping tape is less than a preset error threshold (e.g., less than 1 cm), then the original strapping tape is considered usable. The binding position of this strapping tape is then removed, and it is not re-bundled; the original strapping tape can be used directly. Furthermore, the number of binding positions can be reduced accordingly based on the number of usable original strapping tapes.

[0052] The specific bundling method is not limited here and can be implemented in a manner known to those skilled in the art. When different types of packing straps are available, they can be arranged according to the position arrangement rules of different types of packing straps provided in the aforementioned embodiments. When the original packing strap can be reused, the bundling operation at the location of the original packing strap can be omitted. As an example, when reusing the original packing strap, the integrity of the original packing strap can be verified first through machine vision (for example, taking images of the original packing strap to be reused around the perimeter, extracting image features to obtain the original image features, comparing the original image features with the pre-extracted image features of damaged packing straps; if the comparison fails, it means the original packing strap is intact; otherwise, it is considered that the original packing strap is damaged). If the original packing strap is intact and there is no damage, it can be reused; if there is damage, a new packing strap is still bundled at the corresponding bundling position.

[0053] As another example, after determining the bundling and cutting positions, labels can be set on the scrap steel tail coils by means of painting, affixing, etc., to mark the positions, so that subsequent equipment only needs to identify the corresponding labels to know the corresponding positions.

[0054] In one embodiment, the scrap steel tail coil cutting and processing production line further includes a host computer, which is used to acquire attribute information of the scrap steel tail coil to be cut and processed. The attribute information includes an initial length and a target processing length. The initial length can be understood as the distance between the two end faces of the scrap steel tail coil. The target processing length is a length set by those skilled in the art, and can be set according to the maximum scrap steel length specified by the steelmaking furnace. This target processing length is less than the maximum scrap steel length. Different target processing lengths can also be set for scrap steel tail coils of different materials. The target processing length can also be a value determined based on a preset processing length range and the initial length. For example, if the initial length is 5 meters and the preset processing length range is 1 meter to 1.2 meters, the target processing length can be determined to be 1 meter, so that the scrap steel tail coil to be processed can be cut into 5 pieces. As another example, if the initial length is 5.5 meters and the preset processing length range is 1 meter to 1.2 meters, the target processing length can be determined to be 1.1 meters, so that the scrap steel tail coil to be processed can be cut into 5 pieces.

[0055] In one embodiment, the attribute information may further include data such as the weight and material of the scrap steel coil for subsequent processing. For example, the melting point can be known based on the material, making it easier to determine the preset target temperature for subsequent flame cutting. Knowing its weight allows for the estimation of the amount of scrap steel coil that can be added to the steelmaking furnace, thus facilitating production planning. The weight can be obtained by weighing the scrap steel coil to be processed in advance by transferring it to a load-bearing device using a transfer device.

[0056] As an example, this attribute information can be determined by the production line from which the scrap steel coil to be processed originates, or by other means known to those skilled in the art, without limitation here.

[0057] In one embodiment, the transfer device can also be used to transfer the finished scrap steel to a corresponding target storage warehouse according to the type of strapping on the finished scrap steel.

[0058] As an example, for ease of management, the production line also includes a labeling device to affix a corresponding label to each finished scrap steel product. The label can be made of a material that does not affect the reuse of the scrap steel and indicates information such as the material, weight, and length of the finished scrap steel product.

[0059] If the baling straps on the finished scrap steel products are of the same type, then this batch of finished scrap steel products will be transported to the same target storage warehouse. However, as mentioned in the example provided above, there may be finished scrap steel products with at least two types of baling straps. In this case, target storage warehouses corresponding to different baling strap types can be pre-defined, and then the scrap steel products can be stored accordingly. Multiple target storage warehouses can be physically separated, or they can be different storage areas within the same storage space. This allows for the selection of appropriate finished scrap steel products for utilization as needed.

[0060] The production line provided above is illustrated below with a specific embodiment. This processing can be achieved through intelligent flame cutting. Specifically, the weight, width, material, and length of the processed scrap steel coil are input into the HMI (Human Machine Interface) of the intelligent production line for flame cutting and processing of scrap steel tail coils (attribute information of the scrap steel tail coil to be cut); the scrap steel tail coil to be cut is transferred to the coil support at the packing station; an automatic packing robot is used to bundle the scrap steel tail coil with multiple packing straps, the number of straps (number of binding positions) being the same as the number of small coil segments to be cut. Taking an initial length that is an integer multiple of the target processing length as an example, the distance between the first and last strapping strips and the edge of the scrap steel tail coil is half the required length of the small coil after cutting (i.e., the length of the processed scrap steel, the target processing length), while the distance between the two strapping strips is the length of the small coil after cutting (the target processing length); the scrap steel tail coil to be cut is moved to the cutting station support; a cutting robot moves multiple flame cutting torches to the upper surface of the scrap steel tail coil, aligning them with the midpoint between each pair of strapping strips; the flame cutting torches are heated, oxygen and gas are turned on, and ignition is performed to heat the midpoint between the two strapping strips; optical... A pyrometer detects the temperature of the heating point. When the temperature is about 100°C above the melting point (i.e., the preset target temperature is reached), the slag-blowing oxygen of the flame cutting torch is turned on to perform flame cutting. The scrap steel tail coil is rotated to achieve relative movement between itself and the flame cutting torch, thus achieving the cutting purpose until the cut seam is continuous around the scrap steel tail coil, cutting the scrap steel tail coil into two or more small scrap steel coils. The scrap steel tail coil is then moved to the steel coil support at the flattening station, where upper and lower hydraulic heads are used to flatten the small scrap steel coils, thus forming the finished scrap steel product. The finished scrap steel product is then removed from the steel coil support at the flattening station of the scrap steel coil processing line and enters the storage warehouse (the corresponding target storage warehouse).

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
