Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum product processing, and in particular relates to a cutting device and process for aluminum product processing. Background Art

[0002] In the field of aluminum product processing, especially for cutting long profiles for doors and windows, existing technology typically uses a double-head cutting machine for fixed-length cutting operations. This type of cutting device mainly consists of a fixed cutting unit and a movable cutting unit. Its operating principle is to adjust the position of the movable cutting unit relative to the fixed cutting unit to ensure that the distance between the two is consistent with the required profile length. The profile is then fixed to the machine tool for cutting.

[0003] like Figure 8 As shown, when the profile to be cut is relatively short (for example, the wide side of a door or window), multiple sections of the same length can be obtained by sequentially cutting the same raw material. This method can be effectively applied in actual production. However, for the long side of a door or window, since its length usually exceeds half of the total raw material length, the remaining length of the raw material after a single cut is insufficient to meet the need for further cutting of the same specification long profile. Although the remaining raw material length can still be used to cut short profiles, its collection and storage process can easily lead to low raw material utilization and material accumulation, increasing production management costs.

[0004] Another solution is to optimize the cutting sequence of long and short profiles by first cutting the longer profiles and then adjusting the position of the active cutting unit to cut the shorter profiles, thereby maximizing the use of raw materials. However, this approach has significant drawbacks in practice: First, the position of the active cutting unit must be frequently adjusted before each cut, increasing equipment commissioning time and significantly reducing production efficiency. Second, the spacing between the cutting units must be manually verified after each adjustment, which not only increases labor intensity but also affects cutting accuracy due to manual errors, making it difficult to meet the requirements of high-precision production.

[0005] Therefore, we propose a cutting device and process for aluminum product processing to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems of low production efficiency and unstable cutting accuracy in the existing technology for cutting door and window profiles when processing profiles of different lengths, and to propose a cutting device and process for aluminum product processing.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

A conveying trough is provided on the body, the conveying trough being located directly below the fixed cutting unit and the movable cutting unit.

[0009] A horizontally arranged rotating rod is provided on one side of the conveying trough, and a plurality of equally spaced rotating assemblies are installed on the rotating rod. The rotating assemblies include a plurality of rotating plates, which are arranged in a circular array around the axis of the rotating rod for carrying aluminum products.

[0010] A shell is provided on both sides of the rotating rod. A driving element is installed in the shell to drive the rotating rod to rotate around its axis, so as to transfer the aluminum products away from the conveying trough to the side close to the conveying trough.

[0011] Preferably, each group of the rotating components includes four rotating plates, and the four rotating plates are arranged vertically in pairs and distributed in a cross shape.

[0012] Preferably, it further comprises a base arranged below the shell, wherein a lifting cylinder is arranged in the base, and an output end of the lifting cylinder is arranged vertically upward and fixedly connected to the bottom of the shell.

[0013] Preferably, a push rod is provided on one side of the conveying trough, and the push rod is arranged along the length direction of the conveying trough. A telescopic cylinder for driving the push rod is fixedly connected to the machine body.

[0014] Preferably, the output end of the telescopic cylinder is fixedly connected to the side of the push rod away from the rotating rod, and the side of the conveying trough close to the rotating rod is provided with a lifting rod, and the lifting rod can switch back and forth between the first position and the second position;

[0015] When the lifting rod is in the first position, the upper surface of the lifting rod is higher than the upper surface of the conveying roller assembly, so that the push rod can push the aluminum product and act on the side wall of the lifting rod to adjust the position of the aluminum product;

[0016] When the lifting rod is located at the second position, the upper surface of the lifting rod is lower than the upper surface of the conveying roller assembly, so that the pushing rod can push the aluminum product away from the conveying roller assembly.

[0017] Preferably, a fixing seat is fixedly connected to the opposite side walls of the two shells, a movable plate is rotatably connected between the two fixing seats, and the rotation center of the movable plate is arranged close to the outer side of the movable plate, so that the inner side of the movable plate can rotate;

[0018] The fixing seat has a supporting surface, and the side wall of the body is fixedly connected with a stopper;

[0019] When the movable plate moves to the lower position along with the housing, the inner side of the movable plate acts on the stopper, so that the movable plate is in a tilted downward state;

[0020] When the movable plate moves to an upper position along with the housing, the movable plate is separated from the stopper and acts on the supporting surface, so that the movable plate is in a horizontal state.

[0021] Preferably, the upper end of the base is fixedly connected to a support platform, and when the lifting cylinder is in a retracted state, the lower surface of the shell acts on the upper surface of the support platform.

[0022] Preferably, it also includes a storage rack, on which a first conveyor belt and a second conveyor belt are installed, the first conveyor belt is located above the second conveyor belt, the output end of the first conveyor belt is connected to the rotating assembly, and is used to transport the aluminum products toward the rotating assembly; the input end of the second conveyor belt is connected to the movable plate, and is used to transport the aluminum products to the outside.

[0023] The present invention also provides a cutting process for aluminum product processing, which is applicable to the above-mentioned cutting device and comprises the following steps:

[0024] moving the movable cutting unit to a first position so that the distance between the movable cutting unit and the fixed cutting unit is set to a first distance;

[0025] Placing a plurality of aluminum products on the conveying roller assembly in sequence, and performing a first cutting on the plurality of aluminum products in sequence by using a fixed cutting unit and a movable cutting unit; and obtaining a first finished product of a first length and an aluminum product of a first remaining length by the first cutting;

[0026] moving the movable cutting unit to a second position so that the distance between the movable cutting unit and the fixed cutting unit is set to a second distance;

[0027] placing the aluminum product of the first remaining length above the conveying roller assembly, and performing a second cutting on the aluminum product by the fixed cutting unit and the movable cutting unit; obtaining a second finished product of a second length and a second aluminum product of the second remaining length by the second cutting;

[0028] Repeat the above steps until the remaining part of the aluminum product is not enough to cut into a new finished product.

[0029] Preferably, after a single cutting is completed, the finished product and the aluminum product are simultaneously conveyed forward by the conveyor roller assembly, so that the finished product falls from the output end of the conveyor roller assembly, the finished product and the aluminum product are separated, and then the aluminum product is collected and waits for the next round of cutting operation.

[0030] To sum up, the technical effects and advantages of the present invention are: the cutting device for aluminum product processing realizes the automatic transfer and positioning of aluminum products through the cooperation of the rotating component and the conveying roller component, and combines the position adjustment strategy of the movable cutting unit to effectively reduce manual intervention and material accumulation, and improve cutting accuracy and raw material utilization.

[0031] This aluminum cutting process optimizes the continuous cutting of multiple finished products within a single cycle, automatically moving the remaining material into the next cutting cycle, eliminating the need for repeated manual loading and positioning.

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] In traditional aluminum profile cutting processes, the processing of long profiles faces multiple technical bottlenecks. When implementing fixed-length cutting on a double-head cutting machine, the displacement adjustment of the active cutting unit relies on manual operation, which prolongs the equipment calibration cycle and directly affects the continuous operation capacity of the production line. The remaining material generated after segmented cutting of the raw material cannot be directly transferred to the next process due to insufficient length, resulting in interruptions in the material flow path and accumulation in the secondary processing area. Operators need to repeatedly intervene in equipment parameter settings, introducing the risk of human error, causing the verticality deviation of the cut surface to exceed the tolerance range, affecting the profile assembly accuracy.

[0045] For example, in the door and window manufacturing production line, when processing standard aluminum profiles with a length of 6 meters, it is necessary to cut a combination of 3.2-meter long-side profiles and 2.8-meter short-side profiles. The existing equipment needs to first position the movable cutting unit to the 3.2-meter cutting position. After completing the first section of cutting, it needs to be stopped and readjusted to the 2.8-meter cutting position. During this process, the conveying system needs to suspend operation and wait for the equipment parameters to be reset, resulting in an extension of the production line cycle. The 2.8-meter remaining material after cutting cannot be adapted to the initial positioning reference and needs to be manually transferred to the temporary storage area, resulting in congestion in the material buffer zone. The operator needs to repeatedly check the spacing between the cutting units using a laser rangefinder. The accumulated calibration error results in a misalignment gap of more than 0.5 mm at the interface of adjacent profiles.

[0046] If these issues are not addressed, material flow efficiency will continue to fall below the equipment's theoretical processing capacity, leading to increased unit energy consumption. Excess material accumulation will occupy more than 30% of the workspace, forcing adjustments to the production line layout and increasing the need for material handling equipment. Increased manual intervention will increase equipment idle time, causing the overall efficiency index to drop below 65%. Fluctuations in cutting accuracy will cause diagonal errors in door and window frames to exceed industry standards, leading to increased secondary processing and increased unit production costs.

[0047] When faced with the above problems, the present application first considers how to achieve the continuity and automation of material flow during the cutting process of aluminum products, so as to eliminate the efficiency loss caused by manual intervention. In the prior art, there are operational breakpoints in the adjustment of the cutting unit spacing and the processing of residual materials. To this end, the present application attempts to spatially integrate the conveying channel and the residual material storage area, and realize the automatic return of materials through a rotating bearing structure. Among them, the introduction of the rotating rod can construct a circulation workstation to replace the traditional linear temporary storage rack, but the connection accuracy problem between the rotating plate and the conveying roller needs to be solved. Further analysis found that the use of multiple groups of equidistantly distributed rotating components can form a segmented bearing area, and cooperate with the driving element to control the rotation angle, which can complete the residual material storage and re-feeding functions in a limited space. Compared with the robotic arm grasping solution, this structure has the advantages of fixed running trajectory and simple control logic, which can avoid the increase in maintenance costs caused by complex motion mechanisms.

[0048] like Figures 1-7 As shown, a cutting device for processing aluminum products includes a body 1, a fixed cutting unit 11, and a movable cutting unit 12. A conveying trough 13 is provided on the body 1 and is located directly below the fixed cutting unit 11 and the movable cutting unit 12. A conveying roller assembly 15 is installed in the conveying trough 13 for conveying aluminum products from the movable cutting unit 12 toward the fixed cutting unit 11.

[0049] A horizontally arranged rotating rod 21 is provided on one side of the conveying trough 13. A plurality of equally spaced rotating assemblies are mounted on the rotating rod 21. The rotating assemblies include a plurality of rotating plates 22. The plurality of rotating plates 22 are arranged in a circular array around the axis of the rotating rod 21 to carry aluminum products.

[0050] A housing 23 is provided on both sides of the rotating rod 21. A driving element is installed in the housing 23 to drive the rotating rod 21 to rotate around its axis, thereby transferring the aluminum products away from the conveying trough 13 to the side close to the conveying trough 13.

[0051] Among them, the conveying trough 13 refers to a long strip groove opened on the machine body 1 and located directly below the fixed cutting unit 11 and the movable cutting unit 12. It can be realized by stamping or welding steel plates to form a trough structure, which is used to guide the aluminum products to move along a fixed path to avoid material displacement during the cutting process.

[0052] Among them, the conveying roller assembly 15 refers to a roller conveying mechanism installed in the conveying trough 13, which can be specifically realized by using a motor to drive multiple parallel rollers to rotate, and directional conveying is achieved through the friction between the roller surface and the aluminum product, replacing manual handling and improving positioning accuracy.

[0053] Among them, the rotating rod 21 refers to the rod body horizontally arranged on one side of the conveying trough 13, which can be made of a hollow steel pipe or a solid steel shaft. It drives the rotating assembly to complete the position transfer of the aluminum product by rotating around its own axis, reducing the manual adjustment of the work station operation links.

[0054] The rotating assembly is a load-bearing structure formed by a circular array of multiple rotating plates 22 arranged around the axis of a rotating rod 21. Specifically, each rotating assembly includes four rotating plates 22, arranged perpendicularly to each other in a cross-shaped arrangement. This can be achieved by welding four steel plates into a cross-shaped frame. By alternately switching the load-bearing surface of the rotating plates 22, the aluminum product can be continuously transferred from the non-processing side to the processing side.

[0055] Among them, the driving element refers to a power device installed in the shell 23 to drive the rotating rod 21 to rotate. Specifically, it can be achieved by using a servo motor or a stepper motor in conjunction with a reducer. By precisely controlling the rotation angle, the consistency of the transfer position of the aluminum product is ensured, reducing manual operation errors.

[0056] The core innovation of this application lies in the construction of a multi-station material transfer system within the cutting device, through the coordinated action of the rotating rod 21 and the rotating assembly. This design utilizes the periodic rotation of the rotating plate 22 to automatically transfer aluminum products away from the processing area to the side of the conveyor trough 13. The spatial coordination between the conveyor roller assembly 15 and the rotating assembly forms a closed-loop material flow. Without stopping the machine to adjust the spacing between the cutting units, aluminum products of different lengths can be alternately cut, significantly improving raw material utilization and production efficiency.

[0057] During operation, an aluminum product is first placed on a rotating plate 22, located away from the conveyor trough 13. A drive element rotates the rotating rod 21, causing the rotating plate 22 to move the aluminum product closer to the conveyor trough 13. The aluminum product is then transported by the conveyor roller assembly 15 between the fixed cutting unit 11 and the movable cutting unit 12 for cutting. After cutting, the finished product and the remaining material are transported separately. After the first round of cutting is complete, the remaining material is transported back into the device for a second round of cutting, achieving continuous processing.

[0058] In some of the above-mentioned solutions of the present application, the fixed position of the shell 23 makes it impossible to adjust the height of the rotating assembly, making it difficult to adapt to the load-bearing requirements of aluminum products of different thicknesses or sizes, limiting the versatility of the device. At the same time, the excessive height of the rotating assembly will cause difficulty in loading.

[0059] To this end, the present application further includes a base 24 disposed below the housing 23. A lifting cylinder 25 is disposed within the base 24. The output end of the lifting cylinder 25 is vertically upwardly disposed and fixedly connected to the bottom of the housing 23. A support platform 26 is fixedly connected to the upper end of the base 24. When the lifting cylinder 25 is in a retracted state, the lower surface of the housing 23 acts on the upper surface of the support platform 26.

[0060] Among them, the lifting cylinder 25 can be a hydraulic cylinder or an electric push rod, and its output end is fixedly connected to the bottom of the shell 23 by bolts or welding. The lifting stroke range can be set to 50-300 mm to meet the adjustment requirements of aluminum products of different thicknesses. A guide rail is provided inside the base 24, and a slider that cooperates with the rail is installed at the bottom of the shell 23 to ensure that the shell 23 maintains vertical movement during the lifting process. The material of the support platform 26 can be cast iron or steel plate. A rubber buffer pad can be provided on the upper surface of the support platform 26. When the lifting cylinder 25 is retracted to the lowest position, the rubber buffer pad can absorb the impact force when the shell is pressed down. At this time, the support platform 26 bears the entire weight of the shell 23 and the rotating assembly to prevent the lifting cylinder 25 from being deformed due to continuous force. The control system of the lifting cylinder 25 can be integrated with a manual adjustment button or an automatic control module linked to the host computer, for example, by setting different aluminum product thickness parameters to automatically match the lifting height.

[0061] In some of the above-mentioned solutions of the present application, when the aluminum product falls from the rotating assembly to the conveying roller assembly, its position is likely to be skewed, and its position needs to be adjusted.

[0062] In response to this, the present application further proposes that a push rod 14 be provided on one side of the conveying trough 13, and that the push rod 14 be arranged along the length of the conveying trough 13. A telescopic cylinder for driving the push rod 14 is fixedly connected to the machine body 1. The telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder, with its fixed end firmly connected to the machine body 1 and its movable end connected to one end of the push rod 14. To improve stability, the number of telescopic cylinders is set to two, and each acts on both ends of the push rod 14.

[0063] Among them, the push rod 14 extends along the length of the conveying trough 13, and its movement direction is perpendicular to the conveying direction of the aluminum products. The push rod 14 can be a long strip structure made of metal, and its length is comparable to the length of the conveying trough 13, so that the linear stroke of the push rod 14 can cover the adjustment range of the side of the aluminum products. The telescopic cylinder is fixed to the surface of the body 1 through a rigid connection, and its output end forms a linkage relationship with the end of the push rod 14, and the reciprocating motion of the push rod 14 is achieved by hydraulic or pneumatic drive. When the telescopic cylinder is extended, the push rod 14 moves toward the inside of the conveying trough 13, which can contact and push the aluminum products; when the telescopic cylinder is retracted, the push rod 14 moves away from the conveying trough 13, and does not affect the normal transportation of the aluminum products. The stroke length of the push rod 14 can be adjusted according to the actual size of the aluminum products. For example, the stroke range can be set to 50-200 mm to adapt to the width of aluminum products of different specifications.

[0064] In some of the aforementioned solutions of this application, a push rod 14 and a telescopic cylinder are proposed to move the aluminum products. However, this method of adjusting the position is unidirectional and lacks reliable support from the rear, resulting in insufficient precision in adjusting the aluminum products. Furthermore, after the aluminum products are adjusted within the conveyor trough 13, efficient separation of the finished products from the remaining aluminum products becomes a challenge.

[0065] In this regard, the present application further proposes that the output end of the telescopic cylinder is fixedly connected to the side of the push rod 14 away from the rotating rod 21, and a lifting rod 131 is provided on the side of the conveying trough 13 close to the rotating rod 21, and the lifting rod 131 can switch back and forth between the first position and the second position.

[0066] When the lifting rod 131 is in the first position, the upper surface of the lifting rod 131 is higher than the upper surface of the conveying roller assembly 15, so that the push rod 14 can push the aluminum product and act on the side wall of the lifting rod 131 to adjust the position of the aluminum product; when the lifting rod 131 is in the second position, the upper surface of the lifting rod 131 is lower than the upper surface of the conveying roller assembly 15, so that the push rod 14 can push the aluminum product away from the conveying roller assembly 15.

[0067] The lifting stroke of the lifting rod 131 is driven by a cylinder or a linear motor, and the height difference is set to 5-15 mm to ensure that an effective limit is formed in the first position and that it is completely separated from the bottom surface of the aluminum product in the second position. When the push rod 14 pushes the aluminum product, the contact surface between the aluminum product and the side wall of the lifting rod 131 can be set to an inclination angle, for example, 30-60 degrees, to guide the aluminum product to move in a predetermined direction. The switching action of the lifting rod 131 and the telescopic action of the telescopic cylinder are linked by the controller timing. For example, during the position adjustment stage, the lifting rod 131 remains in a high position. During the separation stage, the lifting rod 131 descends and the push rod 14 performs a full-stroke push.

[0068] After cutting is completed, the conveying roller assembly 15 will drive the finished product and the remaining material to move along the length direction. The finished product will fall from the output end of the conveying trough 13 along with the conveying roller assembly 15, and then the remaining material will be pushed away from the side of the conveying trough 13 by the push rod 14, thereby separating the finished product and the remaining material.

[0069] In some of the above-mentioned solutions of the present application, there is a lack of effective guiding mechanism when the aluminum products are transferred from the conveying trough 13 to the outside of the machine body 1, which may easily cause the aluminum products to fall directly or shift in position, thereby causing problems such as unsmooth transfer of residual materials or accumulation and jamming.

[0070] In the present application, fixed seats 28 are fixedly connected to the opposite side walls of the two shells 23, and a movable plate 27 is rotatably connected between the two fixed seats 28. The rotation center of the movable plate 27 is set close to the outer edge of the movable plate 27, so that the inner edge of the movable plate 27 can rotate.

[0071] The fixed base 28 has a support surface 281, and a stopper 17 is fixedly connected to the side wall of the housing 1. The fixed base 28 can be L-shaped, with its horizontal portion fixedly connected to the side wall of the housing 23 and its vertical portion extending downward to provide the support surface. The movable plate 27 can be a rectangular plate structure, with its rotation center set a certain distance from the outer edge. The stopper 17 can be a raised structure, fixed to the side wall of the housing 1, and its height can be adjusted as needed.

[0072] The center of rotation of the movable plate 27 is limited to a length range of 5%-15% from the outer edge, for example, at a position of 10% from the outer edge, forming an asymmetric fulcrum structure. The support surface of the fixed seat 28 is set to a horizontal plane or has a slight upward inclination angle of 0°-5°, for example, a 3° inclination angle, which is used to provide stable support when the movable plate 27 is in a horizontal state. The height of the stopper 17 is configured so that when it contacts the inner edge of the movable plate 27, the movable plate 27 forms an inclination angle of 15°-30°, for example, a 20° inclination angle, which serves as a guide surface for the sliding of aluminum products. The movable plate 27 and the fixed seat 28 are connected by a hinge or a rotating shaft, and the rotational friction force is controlled within the range of 0.1-0.3N·m, for example, 0.2N·m, to ensure that the movable plate 27 can swing freely under the action of gravity.

[0073] When the movable plate 27 moves to the lower position along with the shell 23, the inner edge of the movable plate 27 acts on the stop block 17. Since the rotation center is close to the outer edge, the inner edge of the movable plate 27 is blocked by the stop block 17 to form a lever effect, forcing the movable plate 27 to rotate clockwise around the rotation center, so that the movable plate 27 is in a tilted downward state, which facilitates the transfer of the aluminum product along the inclined surface to the outside of the body 1 to reduce the sliding height.

[0074] When the movable plate 27 moves to the upper position along with the housing 23, the movable plate 27 separates from the stopper 17 and acts on the support surface 281. Specifically, the movable plate 27 is freed from the restraint of the stopper 17, and its inner side naturally droops under the action of gravity, causing the movable plate 27 to rotate counterclockwise around the rotation center and contact the support surface 281 of the fixed seat 28, so that the movable plate 27 is in a horizontal state. At this time, the surface of the movable plate 27 is flush with the upper surface of the lifting rod 131 in the second position, forming a transition platform for the push rod 14 to smoothly push the aluminum product onto the movable plate 27.

[0075] During this process, the angle switching of the movable plate 27 relies entirely on the mechanical linkage of the housing 23's lifting and lowering, eliminating the need for a separate drive mechanism. For example, when the housing 23's lifting stroke is 200mm, the movable plate 27 switches between horizontal and tilted positions in less than 0.5 seconds, ensuring the continuity of aluminum product transfer. The offset center of rotation ensures a self-locking effect between the two angles of the movable plate 27, preventing abnormal angle changes caused by vibration.

[0076] In some of the above-mentioned schemes of the present application, the movable plate 27 is used to transfer the cut aluminum products. However, during the cutting process, the aluminum products need to be frequently transferred between the rotating assembly and the movable plate 27. If there is a lack of an efficient material conveying connection structure, the cut finished products and the remaining aluminum products may easily accumulate near the conveying trough 13, requiring frequent manual intervention and transportation, which not only increases labor intensity, but also reduces the overall cutting efficiency due to poor material flow.

[0077] To this end, the device of the present application also includes a storage rack 3, which is configured as a double-layer frame structure. A first conveyor belt 31 and a second conveyor belt 32 are respectively installed on the upper and lower frames of the storage rack 3. The first conveyor belt 31 is located above the second conveyor belt 32. The output end of the first conveyor belt 31 is connected to the rotating assembly to convey the aluminum products toward the rotating assembly; the input end of the second conveyor belt 32 is connected to the movable plate 27 to convey the aluminum products to the outside. The first conveyor belt 31 and the second conveyor belt 32 run in opposite directions. The first conveyor belt 31 conveys the aluminum products to be processed toward the rotating assembly, and the second conveyor belt 32 conveys the cutting residues to a collection area away from the cutting area.

[0078] Specifically, when the output end of the first conveyor belt 31 docks with the rotating assembly, aluminum products are continuously transported to the support area of ​​the rotating plate 22. The rotating rod 21 then rotates, transferring the aluminum products to the cutting station. After cutting, the remaining aluminum products are transferred via the movable plate 27 to the input end of the second conveyor belt 32, where they are automatically discharged to an external collection area. The upper and lower conveyor belts, respectively, handle the input of raw materials and the discharge of residual materials.

[0079] At the same time, in combination with the cutting step of the present application, an additional conveying mechanism can be added to re-input the remaining aluminum products output by the second conveyor belt 1 into the first conveyor belt 31 to facilitate two-round cutting and form a closed-loop conveying path.

[0080] like Figure 7 As shown, the present application also provides a cutting process for aluminum product processing, which is applicable to the above-mentioned cutting device and includes the following steps:

[0081] Move the movable cutting unit 12 to the first position, so that the distance between the movable cutting unit 12 and the fixed cutting unit 11 is set to the first distance; place multiple aluminum products (length A) on the conveying roller assembly 15 in turn, and cut the multiple aluminum products for the first time in turn by the fixed cutting unit 11 and the movable cutting unit 12; and obtain a first finished product of the first length (length a1) and a first remaining length of aluminum products (length B) through the first cutting; move the movable cutting unit 12 to the second position, so that the distance between the movable cutting unit 12 and the fixed cutting unit 11 is set to the second distance; place the aluminum product of the first remaining length on the conveying roller assembly 15, and cut the aluminum product for the second time by the fixed cutting unit 11 and the movable cutting unit 12; and obtain a second finished product of the second length (length a2) and a second remaining length of aluminum products (length C) through the second cutting; repeat the above steps until the remaining part of the aluminum product is not enough to cut into a new finished product.

[0082] It should be noted that after a single cutting is completed, the finished product and the aluminum product are conveyed forward at the same time by the conveyor roller assembly 15, so that the finished product falls from the output end of the conveyor roller assembly 15, separating the finished product and the aluminum product, and then the aluminum product is collected and waits for the next round of cutting operation.

[0083] During the cutting process, after the fixed cutting unit 11 and the movable cutting unit 12 complete a single cut of the aluminum product, the conveyor roller assembly 15 is activated and operates at a constant speed. The finished product and the remaining aluminum products move forward synchronously on the roller surface until they reach the end of the conveyor trough 13. The end of the conveyor trough 13 is open and unobstructed, allowing the finished product to naturally separate from the roller surface due to gravity and fall vertically into the finished product collection box. After the conveyor roller assembly 15 stops operating, the remaining aluminum products are either driven in the reverse direction by the conveyor roller assembly 15 and dropped from the starting end of the conveyor trough 13, or pushed out from the side by a push rod structure and transferred to a temporary storage area, where they await positioning adjustments before the next round of cutting.

[0084] The specific implementation is as follows: First, the movable cutting unit 12 is moved to the first position, and the distance between the movable cutting unit 12 and the fixed cutting unit 11 is adjusted to a first distance, for example, 1200 mm. Then, five aluminum profiles with a length of 6000 mm are placed in sequence on the conveyor roller assembly 15. The fixed cutting unit 11 and the movable cutting unit 12 perform the first cut on the five aluminum profiles in sequence, obtaining a finished segment with a length of 1200 mm and a remaining segment of 4800 mm.

[0085] Then the movable cutting unit is moved to the second position, the spacing is adjusted to the second distance, for example 800 mm, and the five remaining segments are placed back on the conveying roller assembly 15 in sequence for a second cutting to obtain a finished segment with a length of 800 mm and a remaining segment of 4000 mm.

[0086] The movable cutting unit 12 is further moved to the third position, the spacing is adjusted to 3500 mm, and the five remaining segments are cut for the third time. After the finished segments are obtained, the remaining material length is less than 500 mm, and then the operation is stopped.

[0087] Through the above technical solution, the present application realizes the continuous cutting of finished products of multiple specifications in a single process cycle, and automatically enters the next round of cutting process through the remaining materials, avoiding repeated manual loading and positioning operations. The number of position adjustments of the cutting unit corresponds to the number of times the remaining material can be cut, so that the utilization rate of raw materials is maximized, while eliminating the cumulative errors caused by manual handling and multiple positioning. This process connects the cutting operations of finished products of different specifications by programmatically controlling the displacement parameters of the cutting unit and the process, so that the cutting operations of finished products of different specifications form a closed-loop process, effectively solving the problems of low utilization rate of remaining materials and limited production efficiency in traditional processes.

[0088] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
