Description

Technical Field

[0001] This utility model relates to the technical field of cold bending forming equipment, specifically to a multi-axis linkage servo drive system for cold bending forming equipment. Background Technology

[0002] In the field of modern metal processing, cold bending forming technology, with its significant advantages of high efficiency, high precision, and high material utilization, has become the core process for the production of long and thin metal profiles in industries such as construction, automobiles, and machinery manufacturing. However, with the increasing market demand for complex cross-section profiles and irregularly shaped components, traditional cold bending equipment is gradually showing limitations in terms of multi-segment synchronous pressure application accuracy, forming efficiency, and structural stability. Especially in the cold forging of thin-walled profiles such as color steel tiles, how to achieve multi-segment coordinated pressure application, ensure forming consistency, and simplify the transmission structure to reduce maintenance costs has become a technical challenge that the industry urgently needs to overcome.

[0003] For example, the patent with authorized patent announcement number CN219837446U discloses a color steel tile forming machine, which relates to the field of color steel tile technology. The color steel tile forming machine includes a frame body, and two film-coating roller support frames are welded on the upper part of the frame body. One of the film-coating roller support frames has a U-shaped groove to facilitate the overlap of the film-coating rollers. A film-coating roller is set between the two film-coating roller support frames. In this utility model, the color steel tile is squeezed and conveyed by the forming roller, thereby driving the protective film to move. Under the pull of the protective film, the film-coating roller rotates on the film-coating roller support frame, releasing the protective film on the film-coating roller. When the protective film on the film-coating roller is used up, the end of the film-coating roller connected to the bearing seat can be disassembled, the film-coating roller can be removed, and a new protective film can be installed. The pressing roller sliding frame is slidably connected in the slot of the pressing roller support frame, thereby driving the pressing roller above to move, which facilitates the adjustment of the distance between the pressing rollers and provides film protection for color steel tiles of different thicknesses.

[0004] However, the aforementioned color steel tile forming machine uses multiple sets of roller forming components to roll and form the color steel tiles in stages during the cold bending process. This makes the sheet material prone to slight deviations due to insufficient rigidity during continuous conveying. This can easily lead to cumulative errors in key parameters such as the cross-sectional dimensions and curvature of the color steel tile. Especially for color steel tiles with irregular cross-sections or multi-peak structures, simple roller forming cannot guarantee the consistency of forming accuracy in each stage, and defects such as local waves and twists are likely to occur. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-axis linkage servo drive system for cold bending forming equipment, so as to solve the defects mentioned in the background art, such as the cumulative error of offset caused by insufficient rigidity, low forming accuracy of complex cross sections, and easy generation of wave distortion in color steel tiles during continuous rolling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-axis linkage servo drive system for a cold bending forming equipment includes: a base plate, on the upper surface of which multiple sets of roll forming components and a girder are fixedly mounted. The multiple sets of roll forming components operate synchronously through chain transmission. The roller profiles are segmented according to the forming curve of the color steel tile, and are responsible for continuously and progressively shaping the sheet material. Each set of girder is located between every two sets of roll forming components, and a first forging tooth is fixedly mounted on the lower surface of the girder. A cold forging mechanism is slidably mounted on the upper half of the girder. The multiple sets of cold forging mechanisms work together to gradually increase the deformation along the conveying direction, ultimately achieving precise cold bending forming of the color steel tile.

[0007] Preferably, the multiple sets of the roll forming components can intermittently convey the color steel tile material between the multiple sets of first forging teeth and the cold forging mechanism.

[0008] Preferably, during each intermittent conveying of the color steel tile material by the roll forming assembly, multiple sets of cold forging mechanisms will slide together in the U-shaped frame to form multiple sets of engagement points with the fixed first forging teeth, thereby realizing synchronous cold forging processing of different sections of the color steel tile material.

[0009] Preferably, the cold forging mechanism includes a U-shaped frame, the U-shaped frame is slidably installed inside the U-shaped frame and guide columns are fixedly installed on the outer surface of both sides, and a second forging tooth is fixedly installed on the lower surface of the U-shaped frame, the second forging tooth being able to form multiple sets of engagement points with the first forging tooth.

[0010] Preferably, each set of the sculpted frame has a through-type rotating slot on its top, and an eccentric shaft is rotatably mounted in each rotating slot via a transmission column. The transmission column can rotate through multiple sets of sculpted frames and one end is fixedly connected to the output shaft of a servo motor. The servo motor is fixedly mounted at one end of one set of sculpted frames, thereby enabling one set of transmission columns to drive multiple sets of eccentric shafts to rotate synchronously in multiple sets of rotating slots.

[0011] Preferably, a connecting arm is rotatably mounted on the outer surface of the eccentric shaft, and the other end of the connecting arm is rotatably mounted on the outer surface of the crossbar, while the crossbar is fixedly mounted on the upper surface of the U-shaped frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the design of roll forming components, a girder, a rotating groove, a first forging tooth, and a cold forging mechanism, multiple roll forming components operate synchronously via chain drive. The roller profiles are segmented according to the forming curve of the color steel tile. During operation, the roll forming components convey the color steel tile sheet forward intermittently, continuously and gradually shaping the sheet during this process, bringing it closer to the basic shape of the target cross-section. When the sheet is intermittently conveyed to the girder area between two roll forming components, it is positioned between the first forging tooth on the lower surface of the girder and the upper cold forging mechanism. At this point, the roll forming components can pause conveying. Subsequently, multiple cold forging mechanisms can perform a coordinated reciprocating slide within the girder, forming multiple engagement points with the fixed first forging tooth. This allows for synchronous cold forging of different sections of the color steel tile sheet. Furthermore, as the processing progresses, the multiple cold forging mechanisms... The deformation of the sheet metal is gradually increased along the conveying direction. With the intermittent conveying of the roll forming component and the periodic coordinated cold forging of the cold forging mechanism, the sheet metal undergoes gradual shaping and setting, ultimately achieving precise cold bending and forming into a qualified color steel tile product. The design of gradually increasing the deformation along the conveying direction through the cold forging mechanism enables precise synchronous cold forging for different sections. Especially for complex structures such as multi-arc and irregular cross-sections, millimeter-level precision shaping can be achieved through directional pressure control, thus solving the problem that single roll forming cannot ensure the consistency of dimensions across multiple sections. At the same time, the alternating rhythm of intermittent conveying and periodic cold forging ensures the sufficiency of each section's processing and avoids efficiency losses caused by process interruptions through the coordinated action of multiple mechanisms. Compared with the traditional "single forming + multiple corrections" mode, the process time is significantly reduced. Furthermore, the synchronicity of chain drive ensures a high degree of consistency in the forming quality of each color steel tile in mass production.

[0013] 2. Through the design of servo motors, transmission columns, eccentric shafts, connecting arms, U-shaped frames, crossbars, and second forging teeth, during the cold forging stage, the output shaft of the servo motor can be started to rotate the transmission column that runs through multiple sets of U-shaped frames. This, in turn, allows the transmission column to drive multiple sets of eccentric shafts fixed to the outer surface to rotate within the rotating slots of each U-shaped frame. The rotating eccentric shafts then drive the connecting arm to perform eccentric motion. The crossbar, rotatably connected to the other end of the connecting arm, drives the U-shaped frame to move, sliding vertically back and forth along the outer surface of the guide column within the U-shaped frame. When the U-shaped frame slides downwards, its lower surface is fixed... The second forging tooth can be driven to move downwards, forming multiple engagement points with the first forging tooth on the lower surface of the U-shaped frame. This allows for cold forging of the corrugated steel sheet material between them. When the U-shaped frame slides upwards, the second forging tooth separates from the first forging tooth, completing one cold forging cycle. Through precise control of the servo motor and the coordinated linkage of the transmission column, eccentric shaft, and other structures, it is ensured that the second forging teeth on multiple sets of U-shaped frames can simultaneously engage or separate from the first forging teeth. This achieves synchronous and precise cold forging of different sections of the corrugated steel sheet material, ensuring the accuracy and effect of cold bending forming. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This embodiment provides the following technical solution: like Figures 1-3 As shown, a multi-axis linkage servo drive system for a cold bending forming equipment includes: a base plate 1, on which multiple sets of roll forming components 101 and girder frames 102 are fixedly installed. The multiple sets of roll forming components 101 are synchronously operated through chain transmission. The roller profiles are segmented according to the forming curve of the color steel tile, and are responsible for the continuous and progressive preliminary shaping of the sheet. Each girder frame 102 is located between every two sets of roll forming components 101, and a first forging tooth 104 is fixedly installed on the lower surface of the girder frame 102. A cold forging mechanism 2 is slidably installed in the upper half of the girder frame 102. Multiple sets of cold forging mechanisms 2 together gradually increase the deformation along the conveying direction, and finally realize the precise cold bending forming of the color steel tile.

[0018] Multiple sets of roll forming components 101 can intermittently convey color steel tile material between multiple sets of first forging teeth 104 and cold forging mechanism 2. During each intermittent conveying of color steel tile material by the roll forming components 101, multiple sets of cold forging mechanisms 2 will perform a coordinated reciprocating sliding motion within the U-shaped frame 102, forming multiple engagement points with the fixed first forging teeth 104, thereby achieving synchronous cold forging processing of different sections of the color steel tile material.

[0019] Through the design of the roll forming assembly 101, the girder 102, the rotating groove 103, the first forging tooth 104, and the cold forging mechanism 2, multiple roll forming assemblies 101 are synchronized through chain drive. The roller profiles are segmented according to the forming curve of the color steel tile. During operation, the roll forming assembly 101 conveys the color steel tile sheet forward in an intermittent conveying manner, and continuously and gradually performs preliminary shaping on the sheet during the conveying process, causing the sheet to gradually approach the basic shape of the target cross-section until the sheet is intermittently... When the corrugated steel sheet is conveyed to the area of ​​the U-shaped frame 102 between the two sets of roll forming components 101, it will be positioned between the first forging tooth 104 on the lower surface of the U-shaped frame 102 and the upper cold forging mechanism 2. At this time, the roll forming component 101 can pause conveying. Subsequently, multiple sets of cold forging mechanisms 2 can perform a coordinated reciprocating slide within the U-shaped frame 102, forming multiple sets of engagement points with the fixed first forging tooth 104, thereby achieving synchronous cold forging processing of different sections of the corrugated steel sheet. The processing progresses to allow multiple sets of cold forging mechanisms 2 to gradually increase the deformation of the sheet metal along the conveying direction. With the intermittent conveying of the roll forming component 101 and the periodic coordinated cold forging of the cold forging mechanism 2 alternating, the sheet metal undergoes gradual shaping and setting, ultimately achieving precise cold bending and forming into a qualified color steel tile product. The design of gradually increasing the deformation of the cold forging mechanism 2 along the conveying direction enables precise synchronous cold forging of different sections. Especially for complex structures such as multi-arc and irregular cross-sections, millimeter-level precision shaping can be achieved through directional pressure control, thus solving the problem that a single roll forming process cannot achieve dimensional consistency across multiple sections. Furthermore, the alternating rhythm of intermittent conveying and periodic cold forging ensures sufficient processing for each section and avoids efficiency losses caused by process interruptions through the coordinated action of multiple mechanisms. Compared with the traditional "single forming + multiple corrections" mode, this significantly reduces process time. At the same time, the synchronicity of chain drive ensures a high degree of consistency in the forming quality of each color steel tile in mass production.

[0020] like Figures 4-5 As shown, the cold forging mechanism 2 includes a U-shaped frame 205. The U-shaped frame 205 is slidably installed inside the U-shaped frame 102. Guide columns 105 are fixedly installed on the outer surface of both sides. A second forging tooth 207 is fixedly installed on the lower surface of the U-shaped frame 205. The second forging tooth 207 can form multiple sets of engagement points with the first forging tooth 104.

[0021] Each set of U-shaped frames 102 has a transversely extending rotating groove 103 at its top. An eccentric shaft 203 is rotatably mounted within each rotating groove 103 via a transmission column 202. The transmission column 202 rotatably passes through multiple sets of U-shaped frames 102, with one end fixedly connected to the output shaft of a servo motor 201. The servo motor 201 is fixedly mounted at one end of one set of U-shaped frames 102, thus enabling one set of transmission columns 202 to drive multiple sets of eccentric shafts 203 to rotate synchronously within the multiple rotating grooves 103. A connecting arm 204 is rotatably mounted on the outer surface of the eccentric shaft 203. The other end of the connecting arm 204 is rotatably mounted on the outer surface of a crossbar 206, which is fixedly mounted on the upper surface of the U-shaped frame 205.

[0022] Through the design of the servo motor 201, transmission column 202, eccentric shaft 203, connecting arm 204, U-shaped frame 205, crossbar 206, and second forging tooth 207, during the cold forging stage, the servo motor 201 can be started to drive the output shaft to rotate the transmission column 202 that runs through multiple sets of U-shaped frames 102. This allows the transmission column 202 to drive multiple sets of eccentric shafts 203, which are fixedly mounted on the outer surface, to rotate within the rotation groove 103 of each set of U-shaped frames 102. The rotating eccentric shafts 203 then drive the connecting arm 204 to perform eccentric motion. The crossbar 206, rotatably connected to the other end of the connecting arm 204, drives the U-shaped frame 205 to move within the U-shaped frame 102, reciprocating vertically along the outer surface of the guide column 105. When the U-shaped frame 205... When the U-shaped frame 205 slides downward, the second forging tooth 207 fixedly installed on its lower surface can be driven to move downward, so that it forms multiple sets of engagement points with the first forging tooth 104 on the lower surface of the U-shaped frame 102, allowing it to perform cold forging on the color steel tile sheet between the two. When the U-shaped frame 205 slides upward, the second forging tooth 207 can separate from the first forging tooth 104, completing one cold forging cycle. Thus, through the precise control of the servo motor 201 and the coordinated linkage of the transmission column 202, eccentric shaft 203 and other structures, it is ensured that the second forging tooth 207 on multiple sets of U-shaped frames 205 can simultaneously engage or separate from the first forging tooth 104, realizing synchronous and precise cold forging of different sections of the color steel tile sheet, ensuring the accuracy and effect of cold bending forming.

[0023] Based on the above technical solution, the working steps of this solution are summarized as follows: Multiple sets of roll forming components 101 maintain synchronous operation through chain drive. The roller profiles are segmented according to the forming curve of the color steel tile. During operation, the roll forming components 101 convey the color steel tile sheet forward in an intermittent conveying manner. During the conveying process, the sheet undergoes continuous and gradual preliminary shaping, gradually bringing the sheet closer to the basic shape of the target cross-section, until the sheet is intermittently conveyed to the U-shaped frame 102 between two sets of roll forming components 101. When the area is in the correct position, the corrugated steel sheet will be positioned between the first forging tooth 104 on the lower surface of the U-shaped frame 102 and the second forging tooth 207 on the upper part. At this time, the roll forming assembly 101 can pause conveying and simultaneously start the servo motor 201 to drive the transmission column 202 that runs through multiple sets of U-shaped frames 102 to rotate. This allows the transmission column 202 to drive multiple sets of eccentric shafts 203 fixedly installed on the outer surface to rotate within the rotation groove 103 of each set of U-shaped frames 102. This allows the rotating eccentric shafts 203 to rotate within the rotation groove 103 of each set of U-shaped frames 102. 3. The connecting arm 204 is driven to make an eccentric movement, and the crossbar 206, which is rotatably connected to the other end of the connecting arm 204, can drive the U-shaped frame 205 to move and slide vertically back and forth along the outer surface of the guide post 105 inside the U-shaped frame 102. When the U-shaped frame 205 slides downward, the second forging tooth 207, which is fixedly installed on its lower surface, can be driven to move downward as well, so that it forms multiple sets of engagement points with the first forging tooth 104 on the lower surface of the U-shaped frame 102, allowing it to cool the color steel tile sheet between the two. In the forging process, when the U-shaped frame 205 slides upward, the second forging tooth 207 can separate from the first forging tooth 104, completing one cold forging cycle. As the processing progresses, multiple sets of second forging teeth 207 gradually increase the deformation of the plate along the conveying direction. With the intermittent conveying of the roll forming component 101 and the periodic coordinated cold forging of the second forging teeth 207 alternating, the plate undergoes gradual shaping and setting, ultimately achieving precise cold bending forming to become a color steel tile product that meets the requirements.

[0024] In summary, by combining roll forming and cold forging, precise synchronous cold forging can be carried out for different sections. Especially for complex structures such as multi-arc and irregular cross-sections, millimeter-level precision shaping can be achieved through directional pressure control. This solves the problem that single roll forming cannot ensure the consistency of dimensions across multiple sections, and achieves efficient and precise forming of color steel tiles. Compared with the traditional "single forming + multiple corrections" mode, it significantly reduces the process time.
