Description

Technical Field

[0001] This invention relates to the field of curtain wall profile processing, and in particular to a curtain wall profile feeding device, a curtain wall profile feeding device, a curtain wall profile production line, and their working methods. Background Technology

[0002] With rapidly rising labor costs and intensifying market competition within the industry, the traditional aluminum profile processing and production process for curtain walls has been impacted. Therefore, reducing production costs, improving product quality, and increasing production efficiency are of paramount importance. Curtain wall profile processing and production mainly includes profile loading, dimensional cutting, forming, and unloading steps. The following drawbacks exist during production: manual labor or forklifts are required for handling between adjacent processes, resulting in large handling volumes, potential damage to profiles, cut semi-finished products, and finished products, and long turnaround times, significantly reducing production efficiency.

[0003] In the prior art, Chinese invention patent application publication number CN113568388A discloses an automated production line for processing aluminum profiles for curtain walls. This line includes a truss unit and sequentially arranged feeding line system unit, cutting unit, semi-finished product buffer unit, processing unit, and unloading line system unit. The feeding line system unit includes a feeding conveyor line, a feeding lifting roller module, and a feeding tilting module. The cutting unit includes several tooling fixtures, a robotic cutting module, and a chip removal module. The semi-finished product buffer unit includes a ground rail conveying module, a buffer lifting module, and several clamping modules. The unloading line system unit includes an unloading conveyor line, an unloading lifting module, and an unloading tilting module. During production, the aluminum profiles are manually fed... The aluminum profiles are fed into the loading system unit, where a truss unit clamps and flips them before conveying them to the cutting unit. A robotic cutting module cuts the aluminum profiles into semi-finished products. These semi-finished products are then clamped and conveyed to a semi-finished product buffer unit via another truss unit for buffering. Next, they are clamped and conveyed to a corresponding CNC machining center for processing into finished products. Finally, the finished products are clamped and conveyed to the unloading system unit via another truss unit. The finished products are flipped and lowered to contact the unloading conveyor line for further transport. Finally, they are unloaded manually, completing the production process. This technology eliminates the need for manual forklift handling, reducing transportation time. Furthermore, the orderly buffering of semi-finished products ensures product quality and improves production efficiency.

[0004] In the above technical solution, the truss unit includes a truss track, a column moving module, and a lifting clamping module. The two ends of the truss track are respectively set on one side of the feeding line system unit and the unloading line system unit. The column moving module is slidably mounted on the truss track, and the lifting clamping module is mounted on the column moving module. During operation, the column moving module drives the lifting clamping module to move along the truss track to clamp and transport the aluminum profiles of the corresponding unit. As can be seen from the attached drawings in the instruction manual, the lifting clamping module uses a ring-shaped feeding method for the profiles, and the lifting clamping module is cantilevered. This places high demands on the strength of the column moving module, requiring multiple reinforcement designs, resulting in a large overall weight and size. To ensure positional accuracy, the moving speed is not fast, resulting in low production efficiency. In addition, the method of clamping around the middle of the profile means that when the profile size changes, the lifting clamping module needs to be replaced or adjusted, making it inflexible in use. Summary of the Invention

[0005] To address the technical problems of poor applicability and inflexibility of existing curtain wall profile feeding and unloading devices in curtain wall profile production lines, this invention provides a curtain wall profile feeding device, a curtain wall profile production line, and its working method. These devices are flexible in use, suitable for processing profiles of various structures, and have high processing efficiency.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a curtain wall profile feeding device, comprising a feeding assembly, the feeding assembly including a worktable, the worktable being provided with two clamping units; one or both of the clamping units are movable along the worktable; two clamping units are provided, each clamping unit including a support plate, a movable plate and a gripper assembly, the support plate being movably disposed on the worktable along the X direction; the movable plate being movably disposed on the support plate along the Y direction, the movable plate being provided with a gripper assembly that is movably disposed up and down; the gripper assembly includes a mounting plate, the mounting plate being movably disposed up and down. A sensor plate is movably mounted on a movable plate. A limiting block is mounted on the upper part of the sensor plate, which abuts against a limiting seat on the mounting plate. A pressure plate is mounted on the lower part of the sensor plate, which abuts against the upper surface of the profile material. A feeding hook is rotatably mounted on the side of the sensor plate opposite to the pressure plate, and the feeding hook can extend into the cavity of the profile material. One or both support plates have a first sensing element on one side of their lower end, which is used to sense the side of the profile material's end. The mounting plate has a second sensing element, which is used to sense the sensor plate.

[0007] This invention uses a combination of a pressure plate, a feeding hook, and two sensors to clamp the profile material from both ends. Compared with the existing wrap-around clamping technology, it is not limited by the shape and size of the profile cross-section, has better applicability, avoids cantilever support, and the overall structure is subjected to balanced force, has good stability, is suitable for high moving speeds, and has high production efficiency.

[0008] Furthermore, the feeding hook is hinged to the sensing plate via a hinge seat, the feeding hook is rotatably connected to the piston rod of the clamping cylinder, and the cylinder body of the clamping cylinder is rotatably mounted on the sensing plate.

[0009] Furthermore, the sensing plate and the mounting base on the mounting plate are connected by a vertically arranged counterweight spring.

[0010] This invention uses a counterweight spring to apply a certain tension to the induction plate, reducing the force exerted by the pressure plate on the upper surface of the profile material and preventing damage to the profile.

[0011] Furthermore, it also includes a feeding frame, which is disposed on the side of the feeding assembly away from the transverse conveying assembly. The side of the feeding frame close to the feeding assembly is attached to the positioning plate, which is disposed on the ground.

[0012] This invention achieves the positioning of the feeding frame in the width direction of the profile by setting a positioning plate, thus ensuring the accuracy of clamping the profile.

[0013] Furthermore, it also includes a feeding assembly and a transverse conveying assembly. The transverse conveying assembly is arranged parallel to the feeding assembly. The feeding assembly includes a platform with a support roller on it. A conveying claw is movably arranged on the platform, and the conveying claw is capable of clamping the end of the profile. The moving direction of the conveying claw is consistent with the length direction of the profile material.

[0014] This invention also provides a curtain wall profile production line, including a row of sawing machines and machining centers. Each sawing machine includes a transverse belt conveyor assembly. At least two machining centers are provided. The production line also includes the aforementioned curtain wall profile feeding device, with the feeding assembly located at the feeding end of the sawing machine. A feeding conveyor assembly is also included, arranged parallel to the row of sawing machines and machining centers along the profile conveying direction. The feeding conveyor assembly starts at the sawing machine and ends at the foremost machining center. A transverse transfer assembly is also provided on the feeding conveyor assembly at a position corresponding to the sawing machine and machining center. The transverse transfer assembly is used for profile transfer and is capable of lifting... The system includes: a robotic arm assembly comprising a travel guide rail and a robotic arm, the travel guide rail being parallel to the loading and conveying assembly; a six-axis robotic arm with a clamping assembly at its end; the travel guide rail starting at the last machining center and ending at the foremost machining center along the profile conveying direction; an unloading and conveying assembly parallel to one side of the travel guide rail along the profile conveying direction, starting at the last machining center; and an unloading transfer assembly movable up and down at its front end; and an unloading device located on one side of the unloading transfer assembly.

[0015] This invention, through the cooperation of a curtain wall profile feeding device, a feeding conveying component, a robotic arm component, a discharging conveying component, and a discharging device, eliminates the need for manual feeding, discharging, and process turnover compared to existing technologies, achieving fully automated production of curtain wall profiles. This facilitates the creation of unmanned production workshops and ensures high production efficiency and stable production quality.

[0016] Furthermore, the unloading conveyor assembly and the loading conveyor assembly are located on the same side of the machining center.

[0017] This invention arranges the unloading conveyor assembly and the loading conveyor assembly on the same side, so that the robotic arm is arranged on one side and has the dual function of loading and unloading, which greatly improves the utilization efficiency of the robotic arm and reduces the investment cost of the robotic arm.

[0018] Furthermore, both the unloading conveying assembly and the loading conveying assembly are located on the side of the traveling guide rail close to the moving track. Both the unloading conveying assembly and the loading conveying assembly include conveying roller groups. The conveying roller group of the unloading conveying assembly is located above the conveying roller group of the loading conveying assembly, and both layers of the conveying roller groups are located on the same support.

[0019] By arranging the unloading conveyor assembly and the loading conveyor assembly vertically, this invention can save lateral space, bring the robotic arm closer to the machining center, shorten the length of the robotic arm, shorten the relevant lever arm, ensure the stability of the robotic arm's operation, and at the same time avoid the need for reinforcing structures, thus achieving a lightweight structure.

[0020] Furthermore, the feeding device includes a support platform, on which two sets of feeding units are movably arranged. The structure of the feeding unit is the same as that of the clamping unit, and a discharge frame is provided on one side of the support platform.

[0021] The present invention also provides a method for processing curtain wall profiles, using the above-mentioned curtain wall profile production line, comprising the following steps:

[0022] S01: The feeding assembly clamps the profile raw material;

[0023] S02: The feeding assembly places the profile raw material on the transverse conveyor assembly, which then transports it to the support roller of the feeding assembly, where the feeding claws realize the feeding.

[0024] S03: The sawing machine performs sawing, and the sawn profiles are conveyed to the transverse belt conveyor assembly;

[0025] S04: The feeding and conveying components work together with the robotic arm to transfer the sawn profiles to the corresponding processing center;

[0026] S05: The machining center completes the corresponding machining tasks. When different surfaces need to be machined, the robotic arm flips the profile.

[0027] S06: The robotic arm transfers the processed profile to the unloading conveyor assembly, which then transfers the processed profile to the unloading device.

[0028] S07: The unloading device transfers the processed profiles into the discharge frame.

[0029] As can be seen from the above technical solutions, the present invention has the following advantages:

[0030] This invention provides a curtain wall profile feeding device, a curtain wall profile production line, and their working method. Through the cooperation of a pressure plate, feeding hooks, and sensors one and two, the profile material is clamped from both ends. Compared to the existing wraparound clamping method, this is not limited by the profile's cross-sectional shape and size, offering better applicability. It also avoids cantilever support, resulting in a balanced overall structure with good stability, suitable for high-speed movement, and high production efficiency. A positioning plate is used to position the feeding frame along the profile's width, ensuring accurate clamping. The combination of the curtain wall profile feeding device, feeding conveyor assembly, robotic arm assembly, unloading conveyor assembly, and unloading device, compared to existing technologies, eliminates the need for... Manual loading, unloading, and process turnover are required to achieve fully automated production of curtain wall profiles, which is conducive to creating an unmanned production workshop and ensuring high production efficiency and stable production quality. By arranging the unloading conveyor component and the loading conveyor component vertically, that is, placing the loading and unloading on the same side of the machine tool, on the one hand, the robotic arm can be placed on one side, serving the dual function of loading and unloading, which greatly improves the utilization efficiency of the robotic arm and reduces the investment cost of the robotic arm. On the other hand, it can save lateral space occupation, making the robotic arm closer to the machining center, shortening the length of the robotic arm, shortening the related lever arm, ensuring the stability of the robotic arm's operation, and avoiding the need for reinforcement structures, thus achieving a lightweight structure.

[0043] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0045] like Figures 1 to 4 As shown in the figure, this specific embodiment provides a curtain wall profile feeding device, including a transverse conveying assembly 4 and a feeding assembly. The feeding assembly is disposed on one side of the transverse conveying assembly 4, and the conveying direction of the transverse conveying assembly 4 is consistent with the width direction of the profile raw material. Figure 1In the Y-direction shown, the feeding assembly includes a worktable 1, on which two clamping units 2 are movably disposed. Either one or both clamping units 2 can move along the worktable 1. In this specific embodiment, the clamping unit 2 includes a support plate 201, a movable plate, and a gripper assembly. The support plate 201 is movably disposed on the worktable 1, and the direction of movement of the support plate 201 is as follows: Figure 1 The X-axis is shown in the diagram; the movable plate is movably mounted on the support plate 201, and the moving direction of the movable plate is as follows. Figure 1 In the Y direction shown, a gripper assembly is movably mounted on the movable plate. The gripper assembly includes a mounting plate 202, which is movably mounted on the movable plate. A sensing plate 204 is movably mounted on the mounting plate 202 via a slide rail. A limit block is provided on the upper part of the sensing plate 204, which abuts against a limit seat on the mounting plate 202 to prevent the sensing plate 204 from detaching. A pressure plate 205 is provided at the lower part of the sensing plate 204, which abuts against the upper surface of the profile material. A feeding hook is rotatably mounted on the side of the sensing plate 204 opposite to the pressure plate 205. The claw 206, the feeding hook 206, can extend into the cavity of the profile material. The pressure plate 205 and the feeding hook 206 together clamp the end of the profile material. One or two moving plates are provided with a sensor 208 on one side of their lower end. The sensor 208 is used to sense the side of the end of the profile material. The sensor 208 is located at the lower part of the gripper assembly and its position is more protruding than the gripper assembly. In this specific embodiment, only the mounting plate 202 of one end clamping unit 2 is provided with a sensor 208 at its lower part. The mounting plate 202 is provided with a second sensor, which is used to sense the sensing plate 204.

[0046] This specific embodiment uses the cooperation of pressure plate 205, feeding hook 206, sensor one 208 and sensor two to perform an insert clamping from both ends of the profile material. Compared with the existing wrap-around clamping, it is not limited by the shape and size of the profile cross-section, has better applicability, avoids cantilever support, and the overall structure is subjected to balanced force, has good stability, is suitable for higher moving speeds, and has higher production efficiency.

[0047] like Figure 3 As shown, in this specific embodiment, the feeding hook 206 is hinged to the sensing plate 204 via a hinge seat, the feeding hook 206 is rotatably connected to the piston rod of the clamping cylinder 209, and the cylinder body of the clamping cylinder 209 is rotatably mounted on the sensing plate 204.

[0048] like Figure 4As shown, in this specific embodiment, the sensing plate 204 and the mounting base 203 on the mounting plate 202 are also connected by a vertically arranged counterweight spring 207. This specific embodiment uses the counterweight spring 207 to apply a certain pulling force to the sensing plate 204, reducing the force exerted by the pressure plate 205 on the upper surface of the profile material and preventing damage to the profile.

[0049] like Figure 1 As shown, this specific embodiment also includes a feeding frame 3, which is located on the side of the feeding assembly away from the transverse conveying assembly 4. The side of the feeding frame 3 closest to the feeding assembly is in contact with the positioning plate, which is set on the ground. By setting the positioning plate, the feeding frame 3 is positioned in the profile width direction, i.e., the Y direction, to ensure the accuracy of clamping the profile. The feeding frame 3 can be equipped with a power assembly to move it in the X direction. At this time, only one of the two clamping units 2 moves. The sensor 208 on the fixed clamping unit 2 has a positioning function. When the feeding frame 3 drives the profile to move and a sensor 208 moves, the sensor 208 moves. When the sensor 208 at one end contacts or reaches a set distance, the loading trolley 3 stops moving and determines the position of one end. The movable clamping unit 2 at the other end moves a corresponding distance according to the length of the profile to determine the position of the other end of the profile, thereby achieving clamping. In this specific embodiment, in order to reduce costs, the loading frame 3 is placed on the ground by a forklift and set to a fixed position and does not move. Both clamping units 2 at both ends can move. After the clamping unit 2 at one end determines the position of the profile end, the clamping unit 2 at the other end moves a corresponding distance according to the length of the profile to determine the position of the other end.

[0050] like Figure 1 As shown, this specific embodiment also includes a feeding assembly 5, which includes a platform, a support roller on the platform, and a conveying claw movably mounted on the platform. The conveying claw can clamp the end of the profile, and the moving direction of the conveying claw is consistent with the length direction of the profile material.

[0051] In this specific embodiment, the workbench 1 is provided with a slide rail and a rack, and the support plate 201 is provided with a motor and a gear. The support plate 201 moves on the workbench 1 through a motor-gear-rack mechanism. The support plate 201 is provided with a slide rail, and the end of the support plate 201 is provided with a motor. The motor is connected to a lead screw through a synchronous belt mechanism, and the lead screw is connected to the mounting plate 202.

[0052] In this specific embodiment, both the first sensor 208 and the second sensor are photoelectric switches. The first sensor 208 moves closer to the end of the profile material as the support plate 201 moves in the X direction. When the side of the profile is sensed, the X-direction position of the gripper assembly and the end of the profile material is determined. When the lower end of the pressure plate 205 abuts against the upper surface of the profile material, the sensing plate 204 cannot continue to move downward with the mounting plate 202, and the two generate relative movement. The second sensor descends with the mounting plate 202. When the sensing plate 204 is sensed, the Z-direction position of the gripper assembly and the end of the profile material is determined. Since the moving plate has already moved to the end of the support plate 201 when the feeding begins, the feeding frame 3 is limited in the Y-direction position by the positioning plate, that is, the Y-direction position of the gripper assembly and the end of the profile material is limited. It is understandable that the profile material mentioned refers to the first or last profile material in the top row of the feeding frame 3. Since the size of the profile material has been input into the control system, the feeding component can determine the position of other profile materials based on the position of one profile material, combined with its width and height. Furthermore, after determining the clamping position at one end, it determines the clamping position at the other end based on the length of the profile material.

[0053] In this specific embodiment, the structure of the transverse conveyor component 4 is the same as the conveyor belt mechanism of a profile processing system in Chinese invention patent application CN114455247B. It can change the conveying direction of the profile through the conveying and lifting of the belt, which is prior art and will not be described in detail here. The structure of the conveyor claw is the same as the clamping component 2 in a profile processing machine tool and profile production line in Chinese utility model patent application CN218746143U, and will not be described in detail here. Specific Implementation Method Two

[0055] like Figures 5 to 10As shown, this specific embodiment provides a curtain wall profile production line, including a curtain wall profile feeding device, a sawing machine 6, a machining center 9, a feeding conveying assembly 7, a robotic arm assembly 8, and a discharging conveying assembly 10 as described in Specific Embodiment 1. The feeding assembly 5 of the curtain wall profile feeding device is located at the feeding end of the sawing machine 6 and is used to feed the sawing machine 6. The sawing machine 6 includes a transverse belt conveyor assembly 601. The machining center 9 is used for profile hole and groove processing. In this specific embodiment, the machining center 9 is a gantry machining center, and the machining center 9 includes... The machine tool body 901 and the moving track 902 are provided. The machine tool body 901 can move along the moving track 902, which is set on a table. Multiple pneumatic clamping components are also arranged on the table along the length of the profile. At least two machining centers 9 are provided, and in this specific embodiment, three are provided. The three machining centers 9 are arranged along the profile conveying direction. The feeding conveyor 7, the sawing machine tool 6 arranged in a straight line, and the machining centers 9 are arranged in parallel, along the profile conveying direction. The feeding conveyor 7 starts at the sawing machine tool 6 and ends at the foremost machining center 9. The feeding and conveying assembly 7 is also equipped with a transverse transfer assembly 701 at a position corresponding to the sawing machine 6 and the machining center 9. The number of transverse transfer assemblies 701 is the same as the total number of sawing machine 6 and machining center 9. The transverse transfer assembly 701 can be raised and lowered. The robotic arm assembly 8 includes a travel guide rail 802 and a robotic arm 801. The travel guide rail 802 is arranged parallel to the feeding and conveying assembly 7. The robotic arm 801 is a six-axis robotic arm 801. A clamping assembly is provided at the end of the robotic arm 801. The robotic arm 801 can drive the clamping assembly to rotate to meet the requirements. For the processing of multiple surfaces, along the profile conveying direction, the traveling guide rail 802 starts at the last machining center 9 and ends at the first machining center 9. In this specific embodiment, a robotic arm 801 is provided; the unloading conveying component 10 is arranged parallel to one side of the traveling guide rail 802. Along the profile conveying direction, the unloading conveying component 10 starts at the last machining center 9. The front end of the unloading conveying component 10 is provided with an unloading transfer component 1001 that can move up and down; the unloading device 11 is provided on one side of the unloading transfer component 1001 for automatic unloading.

[0056] This specific embodiment, through the cooperation of the curtain wall profile feeding device, the feeding conveying component 7, the robotic arm component 8, the unloading conveying component 10, and the unloading device 11, compared with the prior art, eliminates the need for manual feeding, unloading, and process turnover, realizing fully automated production of curtain wall profiles. This is conducive to creating an unmanned production workshop and ensuring high production efficiency and stable production quality.

[0057] like Figures 8 to 10As shown, machining center 9 requires robotic arm 801 for loading and unloading. Since the processing of profiles involves a lot of work and takes a long time, in order to improve the utilization rate of robotic arm 801, unloading conveyor assembly 10 and loading conveyor assembly 7 are set on the same side of the three machining centers 9, so that robotic arm 801 is arranged on one side and has the dual function of loading and unloading, which greatly improves the utilization efficiency of robotic arm 801 and reduces the investment cost of robotic arm 801.

[0058] like Figure 5 As shown, in order to shorten the length of the robotic arm 801 and improve the stability of the mechanism, in this specific embodiment, both the unloading conveying assembly 10 and the loading conveying assembly 7 include conveying roller groups. The conveying roller group of the unloading conveying assembly 10 is set on the upper part of the conveying roller group of the loading conveying assembly 7, and both layers of conveying roller groups are set on the same support.

[0059] In this specific embodiment, the feeding device 11 includes a support platform, on which two sets of feeding units are movably arranged. Each feeding unit includes a gripper assembly with the same structure as the clamping unit 2. The gripper assembly can move along the X, Y, and Z directions. A discharge frame 1101 is provided on one side of the support platform, and a positioning plate is also provided at the discharge frame 1101 to achieve Y-direction positioning.

[0060] In this specific embodiment, the structures of the transverse transfer component 701 and the unloading transfer component 1001 are the same as those of the transverse conveying component 4 in the first specific embodiment, which can change the conveying direction of the profile; the transverse belt conveying component 601 is a mature product that can be purchased on the market and can realize the transverse conveying of profiles, so its structure will not be described in detail. Specific Implementation Method 3

[0062] This specific embodiment provides a working method for a curtain wall profile production line, using the curtain wall profile production line of Specific Embodiment Two, including the following steps:

[0063] S01: The feeding assembly clamps the profile raw material;

[0064] S02: The feeding component places the profile raw material on the transverse conveyor component 4, which then conveys it to the support roller of the feeding component 5, where the feeding is achieved by the conveying claws;

[0065] S03: The sawing machine 6 performs sawing, and the sawn profile is conveyed to the transverse belt conveyor assembly 601;

[0066] S04: The feeding and conveying assembly 7 and the robotic arm 801 work together to transfer the sawn profiles to the corresponding processing center 9;

[0067] S05: Machining center 9 completes the corresponding machining tasks. When different surfaces need to be machined, robotic arm 801 flips the profile.

[0068] S06: The robotic arm 801 transfers the processed profile to the unloading conveyor assembly 10, and the unloading conveyor assembly 10 transfers the processed profile to the unloading device 11;

[0069] S07: The unloading device 11 transfers the processed profile into the discharge frame 1101.

[0070] In S01, the clamping unit 2 at one end moves until the sensor 208 senses the end of the uppermost profile material in the loading frame 3 and then moves a set distance. The clamping unit 2 on the other side determines the clamping position according to the length of the profile material and moves into place. The gripper assembly descends until the pressure plate 205 abuts against the profile material. The loading hook 206 swings at a set angle and extends into the profile material cavity. The set distance is determined by the X-direction distance between the sensor 208 and the gripper assembly.

[0071] In S05, the sawn profile is transferred to the conveyor roller group of the feeding conveyor assembly 7 by the cooperation of the transverse belt conveyor assembly 601 and the corresponding transverse transfer assembly 701 at the sawing machine tool 6, and then conveyed to the corresponding transverse transfer assembly 701. Under the action of the corresponding transverse transfer assembly 701, the sawn profile moves laterally and is transferred to the pneumatic fixture of the corresponding machining center 9 under the action of the robotic arm 801.

[0072] In S07, after the machining center 9 finishes processing, the robotic arm 801 moves to the corresponding position and transfers the processed profile to the conveying roller group of the unloading conveying assembly 10 for conveying. When it is conveyed to the unloading conveying assembly 1001, the unloading conveying assembly 1001 transfers the processed profile laterally to the unloading device 11.

[0073] As can be seen from the above specific embodiments, the present invention has the following beneficial effects:

[0074] 1. Through the cooperation of pressure plate 205, feeding hook 206, sensor 1 208 and sensor 2, the profile material is clamped from both ends. Compared with the existing technology of surrounding clamping, it is not limited by the shape and size of the profile cross section, has better applicability, avoids cantilever support, the overall structure is evenly stressed and has good stability, is suitable for high moving speed, and has high production efficiency.

[0075] 2. Positioning of the feeding frame 3 in the width direction of the profile is achieved by setting a positioning plate, ensuring the accuracy of clamping the profile;

[0076] 3.
