Description

Technical Field

[0001] This utility model relates to the field of edge rolling machine technology, and in particular discloses a round tube edge rolling machine. Background Technology

[0002] The traditional round tube processing field faces numerous challenges. In terms of production efficiency, previous round tube processing equipment often required significant manual labor for processes such as loading / unloading and edge rolling. Workers had to manually handle the round tubes, resulting in high labor intensity, slow loading / unloading speeds, and disjointed processes, leading to low overall production efficiency, long production cycles, and an inability to meet the ever-increasing market demand. Regarding edge rolling quality, some equipment uses a single edge rolling method and lacks an effective internal and external mold coordination mechanism. During edge rolling, the round tube is prone to deformation, resulting in uneven edge rolling, cracks, wrinkles, and other defects, leading to low product qualification rates and increased production costs. Furthermore, traditional equipment lacks applicability and flexibility, making it difficult to process round tubes of various specifications. It cannot flexibly adjust to round tubes with different inner and outer diameters, and when production processes change, such as requiring specific conveying distances for the round tubes, the equipment struggles to meet these requirements, resulting in poor versatility and limiting its application in different production scenarios. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a round tube edge rolling machine.

[0004] To achieve the above objectives, this utility model provides a round tube edge-rolling machine, including a frame, a loading and unloading module mounted on the frame, and an edge-rolling module. The edge-rolling module performs edge-rolling operations on the round tubes conveyed by the loading and unloading module. The edge-rolling module has a support plate mounted on the frame, an edge-rolling mold mounted on the support plate, a first drive component for driving the edge-rolling mold to reciprocate, and a second drive component for driving the edge-rolling mold to rotate. The first drive component and the second drive component cooperate to drive the edge-rolling mold to achieve automatic edge-rolling operation on the round tubes.

[0005] Furthermore, the edge-rolling die has an inner mold assembly and an outer mold assembly. The inner mold assembly is connected to the output end of the first drive assembly, and the outer mold assembly is connected to the output end of the second drive assembly. The outer mold assembly and the inner mold assembly are coaxially arranged, and the outer mold assembly is sleeved outside the inner mold assembly. The first drive assembly drives the inner mold assembly to move into the inside of the circular tube to abut against and support the inner wall of the circular tube. The second drive assembly drives the outer mold assembly to rotate, so as to cooperate with the inner mold assembly to perform edge-rolling operation on the circular tube.

[0006] Furthermore, the loading and unloading module has a loading component and an unloading component. The loading component has a loading rack mounted on the frame, a first loading belt rotatably mounted on the loading rack, and a loading driver for driving the first loading belt to rotate. The unloading component has an unloading rack mounted on the frame, an unloading belt rotatably mounted on the unloading rack, and an unloading driver for driving the unloading belt to rotate. The loading component transfers the round tube to the edge-rolling module for edge-rolling operation, and the unloading component outputs the edge-rolled round tube from the edge-rolling module to the next process. The two components work together to achieve automatic loading and unloading of the round tube.

[0007] Furthermore, the feeding assembly also has a second feeding belt rotatably mounted on the feeding frame. A synchronous pulley set connects the first feeding belt and the second feeding belt. The first feeding belt and the second feeding belt are arranged on the feeding frame along the feeding direction. The feeding driver drives the first feeding belt to rotate, and the first feeding belt drives the second feeding belt to rotate via the synchronous pulley set. The synchronous pulley set realizes the speed change transmission between the two feeding belts through the combination of pulleys of different diameters, so as to control the distance between multiple round tubes on the two feeding belts.

[0008] Furthermore, the bearing plate is reciprocating on the frame, and the frame is also provided with a third drive assembly for driving the bearing plate to reciprocate. The bearing plate is provided with a lubrication assembly. The third drive assembly drives the bearing plate to move the edge-rolling die and the lubrication assembly to the round tube located on the loading and unloading module. After the upper part of the round tube is softened by the lubrication assembly, the edge-rolling die performs an edge-rolling operation on the round tube.

[0009] Furthermore, the round tube edge rolling machine also includes a clamping and conveying module mounted on the frame and used in conjunction with the loading and unloading module. The clamping and conveying module is located below the edge rolling module and is used to clamp and fix the round tube on the loading and unloading module. The clamping and conveying module includes a conveying component mounted on the frame for reciprocating motion, a conveying drive component for driving the conveying component to reciprocate motion, a clamping component mounted on the conveying component for reciprocating motion, and a clamping drive component for driving the clamping component to reciprocate motion.

[0010] Furthermore, the round tube edge rolling machine also includes a flipping module mounted on the frame. The flipping module is located between the edge rolling module and the loading / unloading module, so that the end of the rolled cylinder can be flipped to cooperate with the subsequent sleeve process. The flipping module has a flipping plate rotatably mounted on the frame, a first flipping driver for driving the flipping plate to rotate, a clamping assembly reciprocating on the flipping plate, and a second flipping driver for driving the clamping assembly to reciprocate. The second flipping driver drives the clamping assembly to approach the round tube and clamp and position it. Then, the first flipping driver drives the flipping plate to flip the round tube positioned by the clamping assembly. The flipped round tube is then transferred to the subsequent sleeve process via the loading / unloading module.

[0011] Furthermore, the flipping module also has a flipping bracket reciprocatingly mounted on the frame, a third flipping driver for driving the flipping bracket to reciprocate, the third flipping driver driving the flipping bracket to move closer to or away from the round tube on the loading / unloading module, the flipping plate reciprocatingly mounted on the flipping bracket, and the movement direction of the clamping component intersecting with the movement direction of the flipping bracket.

[0012] Furthermore, both the loading rack and the unloading rack are equipped with limiting components for assisting in the conveying of the round tubes. The limiting components have a first locking member rotatably mounted on the loading rack, a first adjusting rod rotatably mounted on the first locking member, a second locking member rotatably mounted on the first adjusting rod, a second adjusting rod rotatably mounted on the second locking member, and a limiting plate at the end of the second adjusting rod. The limiting plate is adjusted in position via the adjusting rod, and the adjusting rod is adjusted in length via the locking member. The adjustment directions of the first adjusting rod and the second adjusting rod are arranged intersecting.

[0013] Furthermore, the third drive assembly has a drive motor mounted on the frame, the output end of the drive motor is provided with a helical gear, and the bearing plate is provided with a helical rack that works with the helical gear. The drive motor drives the helical gear to drive the helical rack to make the bearing plate reciprocate. A sliding assembly is also provided between the bearing plate and the frame. The sliding assembly works with the helical gear and the helical rack to make the bearing plate slide back and forth.

[0014] The beneficial effects of this utility model are:

[0015] (1) High-efficiency automated production: It integrates loading and unloading and edge rolling functions, and each module has a clear division of labor; the loading and unloading module automatically transports round tubes, the clamping and handling module realizes automated handling, and the flipping module completes the flipping of the end of the round tube to connect with subsequent processes, reducing manual intervention, reducing labor intensity, and greatly improving production efficiency and continuity.

[0016] (2) Excellent edge curling quality: The inner mold component in the edge curling module supports the inner wall of the round tube, and the outer mold component rotates to cooperate with the edge curling, ensuring a uniform and precise edge curling effect.

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] Please see Figures 1 to 7As shown, the present invention discloses a round tube edge rolling machine, including a frame 1, a loading and unloading module 2 and an edge rolling module 3 mounted on the frame 1. The edge rolling module 3 performs edge rolling operation on the round tubes conveyed by the loading and unloading module 2. The edge rolling module 3 has a support plate 31 mounted on the frame 1, an edge rolling mold 32 mounted on the support plate 31, a first drive component 33 for driving the edge rolling mold 32 to reciprocate, and a second drive component 34 for driving the edge rolling mold 32 to rotate. The first drive component 33 and the second drive component 34 cooperate to drive the edge rolling mold 32 to realize the automatic edge rolling operation of the round tube.

[0028] In actual use, the loading / unloading module 2 and the edge-rolling module 3 are integrated into one unit, completing the entire process from tube conveying to edge-rolling operation in one go. The fully automated operation significantly reduces manual intervention, greatly improves production efficiency, accelerates the production pace, and can meet the needs of large-scale production. The first drive component 33 drives the edge-rolling mold 32 to reciprocate, while the second drive component 34 drives its rotation. The precise cooperation between the two enables all-around, high-precision edge-rolling of the tube, resulting in a uniform and stable edge-rolling effect, effectively reducing edge-rolling defects and improving product qualification rate.

[0029] Each module is centrally mounted on frame 1, resulting in a compact and rational overall structure that occupies little space. This allows companies to flexibly arrange equipment within limited production areas and also reduces the difficulty of equipment installation and commissioning. Two drive components control different movement modes of the crimping die 32, allowing for flexible adjustment of motion parameters based on the material and size of the round tube and specific crimping process requirements. This high adaptability enables the machine to meet diverse production tasks.

[0030] Specifically, the edge-rolling mold 32 has an inner mold assembly 321 and an outer mold assembly 322. The inner mold assembly 321 is connected to the output end of the first drive assembly 33, and the outer mold assembly 322 is connected to the output end of the second drive assembly 34. The outer mold assembly 322 and the inner mold assembly 321 are coaxially arranged, and the outer mold assembly 322 is sleeved on the outside of the inner mold assembly 321. The first drive assembly 33 drives the inner mold assembly 321 to move into the inside of the round tube to abut against and support the inner wall of the round tube, and the second drive assembly 34 drives the outer mold assembly 322 to rotate in coordination with the inner mold assembly 321 to perform edge-rolling operation on the round tube.

[0031] In actual use, the inner mold assembly 321 and the outer mold assembly 322 are coaxially arranged, with the outer mold sleeved outside the inner mold. When the inner mold assembly 321 moves inside the round tube to abut against the inner wall of the tube, and the outer mold assembly 322 rotates to cooperate with the edge rolling, it can act simultaneously from both the inside and outside of the round tube. This coordinated approach ensures that the round tube is subjected to uniform force during the edge rolling process, effectively avoiding problems such as deformation and wrinkles, ensuring the precision and quality of the edge rolling, and improving the product yield. By independently controlling the movement of the inner mold assembly 321 and the outer mold assembly 322 through the first drive assembly 33 and the second drive assembly 34 respectively, the support force of the inner mold and the rotation speed and stroke of the outer mold can be flexibly adjusted according to the round tubes of different specifications (such as pipe diameter, pipe wall thickness, etc.), thereby adapting to the edge rolling requirements of various types of round tubes and enhancing the versatility and applicability of the equipment.

[0032] Connecting the inner mold assembly 321 and the outer mold assembly 322 to the output ends of different drive assemblies allows for more precise motion control of the two assemblies. Operators can accurately set the operating parameters of the first drive assembly 33 and the second drive assembly 34 according to the actual hemming process requirements, achieving precise control over the inner mold support position and the outer mold rotation state, thus ensuring the stability and reliability of the hemming operation.

[0033] Specifically, the loading and unloading module 2 has a loading component 21 and an unloading component 22. The loading component 21 has a loading rack 211 mounted on the frame 1, a first loading belt 212 rotatably mounted on the loading rack 211, and a loading driver 213 for driving the first loading belt 212 to rotate. The unloading component 22 has an unloading rack 221 mounted on the frame 1, an unloading belt 222 rotatably mounted on the unloading rack 221, and an unloading driver 223 for driving the unloading belt 222 to rotate. The loading component 21 transfers the round tube to the edge-rolling module 3 for edge-rolling operation, and the unloading component 22 outputs the edge-rolled round tube from the edge-rolling module 3 to the next process. The two work together to realize the automatic loading and unloading operation of the round tube.

[0034] In actual use, the loading and unloading module 2 is divided into a loading component 21 and an unloading component 22. The loading component 21, through the cooperation of the loading rack 211, the first loading belt 212, and the loading driver 213, can automatically transfer the round tube to the edge-curling module 3. The unloading component 22, through the coordination of the unloading rack 221, the unloading belt 222, and the unloading driver 223, outputs the edge-curled round tube to the next process. This automated loading and unloading operation eliminates the need for frequent manual handling of the round tube, greatly reducing loading and unloading time and enabling the round tube to quickly enter the edge-curling process and be output promptly, improving the continuity and efficiency of the entire production process. By driving the first loading belt 212 to rotate via the loading driver 213 and the unloading belt 222 to rotate via the unloading driver 223, the conveying speed and position of the round tube can be precisely controlled, ensuring a stable state of the round tube during loading and unloading. This helps ensure the positional accuracy of the round tube before and after edge-curling, reduces product quality problems caused by unstable loading and unloading, and improves the consistency and stability of product quality. Automated loading and unloading operations reduce the workload of manual handling of round tubes, lowering the labor intensity for workers. At the same time, compared to manual operation, machine-driven tube delivery is more accurate, avoiding errors caused by inaccurate manual handling and placement, thus improving the accuracy and reliability of loading and unloading, and consequently enhancing the quality and efficiency of the entire production process.

[0035] Specifically, the feeding assembly 21 also has a second feeding belt 214 rotatably mounted on the feeding frame 211. A synchronous pulley set 215 connects the first feeding belt 212 and the second feeding belt 214. The first feeding belt 212 and the second feeding belt 214 are arranged on the feeding frame 211 along the feeding direction. The feeding driver 213 drives the first feeding belt 212 to rotate. The first feeding belt 212 drives the second feeding belt 214 to rotate via the synchronous pulley set 215. The synchronous pulley set 215 realizes the speed change transmission between the two feeding belts through the combination of pulleys of different diameters, so as to control the distance between multiple round tubes on the two feeding belts.

[0036] In actual use, the feeding assembly 21 is equipped with a second feeding belt 214, which is connected to the first feeding belt 212 and the second feeding belt 214 via a synchronous pulley set 215. The synchronous pulley set 215 can achieve variable speed transmission through combinations of pulleys of different diameters, allowing for flexible control of the distance between multiple round tubes on the two feeding belts. In actual production, different round tube crimping processes may have different requirements for the spacing of the round tubes during the conveying process. This design allows for convenient adjustment of the round tube spacing according to specific production needs, thereby improving the equipment's adaptability to different production processes and products, and meeting diverse production tasks. The first feeding belt 212 and the second feeding belt 214 are arranged along the feeding direction, and the first feeding belt 212 is driven to rotate by the feeding driver 213, which in turn drives the second feeding belt 214 to rotate via the synchronous pulley set 215. This transmission method ensures that the two feeding belts operate synchronously and stably. An orderly feeding process helps avoid problems such as collisions and stacking of round tubes during transportation, ensuring that each round tube can be accurately transported to the designated position of the crimping module 3, improving the stability and accuracy of feeding, and thus ensuring the smooth progress of subsequent crimping operations.

[0037] Reasonable control of the tube spacing can make the feeding process more efficient. For example, in some cases, appropriately reducing the tube spacing can increase the number of tubes fed to the crimping module 3 per unit time, thereby improving overall production efficiency; while in other production processes with special requirements for tube spacing, the spacing can be adjusted to meet process requirements, avoiding impacts on production progress or product quality due to improper tube spacing. This flexible spacing control method fully utilizes the equipment's performance and improves its utilization rate. The use of the synchronous pulley set 215 realizes the power transmission between the first feeding belt 212 and the second feeding belt 214. This transmission method has a relatively compact structure and occupies less space. At the same time, the synchronous pulley drive has the advantages of accurate transmission ratio, high transmission efficiency, and reliable operation, which can ensure a stable speed relationship between the two feeding belts, reduce feeding failures caused by transmission instability, reduce equipment maintenance costs and downtime, and improve the reliability and stability of the equipment.

[0038] Specifically, the support plate 31 is reciprocated on the frame 1. The frame 1 is also provided with a third drive assembly 35 for driving the support plate 31 to reciprocate. The support plate 31 is provided with a lubrication assembly 36. The third drive assembly 35 drives the support plate 31 to move the edge-rolling mold 32 and the lubrication assembly 36 to the round tube located on the loading and unloading module 2. After the upper part of the round tube is softened by the lubrication assembly 36, the edge-rolling mold 32 performs an edge-rolling operation on the round tube.

[0039] In actual use, the support plate 31 can reciprocate under the drive of the third drive component 35, automatically moving the crimping die 32 and lubrication component 36 located on it to the round tube on the loading and unloading module 2. This process eliminates the need for manual adjustment of the components, greatly shortening the preparation time and allowing the round tube to quickly enter the crimping process, thus improving the automation level and overall production efficiency. The lubrication component 36 can soften the upper part of the round tube. The softened round tube is easier to deform during crimping, making the crimping operation smoother and reducing crimping defects caused by excessively hard materials, such as cracks and wrinkles, thereby improving the quality of crimping and the product qualification rate.

[0040] The lubrication component 36 softens the round tube while also providing lubrication. During the curling process, it reduces friction between the round tube and the curling die 32, lowers wear on components, extends equipment lifespan, and reduces maintenance and replacement costs. The reciprocating motion of the support plate 31 allows the curling module 3 to flexibly cooperate with the loading and unloading module 2. Regardless of the round tube specifications or production layout, adjustments to the motion parameters (such as stroke and speed) of the support plate 31 can be made to adapt, improving the equipment's applicability to different production scenarios and products, and enhancing its versatility and flexibility.

[0041] Specifically, the round tube edge rolling machine also includes a clamping and conveying module 4 mounted on the frame 1 and used in conjunction with the loading and unloading module 2. The clamping and conveying module 4 is located below the edge rolling module 3 and is used to clamp and fix the round tube on the loading and unloading module 2. The clamping and conveying module 4 includes a conveying component 41 that is reciprocated on the frame 1, a conveying drive component 42 that drives the conveying component 41 to reciprocate, a clamping component 43 that is reciprocated on the conveying component 41, and a clamping drive component 44 that drives the clamping component 43 to reciprocate.

[0042] In actual use, the clamping and conveying module 4 can clamp and fix the round tubes on the loading and unloading module 2, effectively preventing the round tubes from shaking, shifting, or falling during the conveying process. By driving the conveying component 41 to reciprocate through the conveying drive component 42, and driving the clamping component 43 to reciprocate through the clamping drive component 44, the position and movement trajectory of the round tubes can be precisely controlled. This ensures that the round tubes are accurately conveyed to the edge-rolling module 3 for edge-rolling operations, and from the edge-rolling module 3 to the next process, improving the stability and accuracy of the round tube conveying, thereby enhancing product quality. The setup of this module automates the conveying process of the round tubes between the loading and unloading module 2 and the edge-rolling module 3. It eliminates the need for manual handling of the round tubes, reducing manual operation steps, lowering the labor intensity of workers, and improving production efficiency. Furthermore, the automated conveying process can better coordinate with the loading and unloading module 2 and the edge-rolling module 3, forming a continuous and efficient automated production process.

[0043] Because the clamping assembly 43 can reciprocate, the clamping position and force can be adjusted according to different specifications of the round tube, thus adapting to the handling needs of round tubes of various sizes and shapes. This flexibility allows the round tube crimping machine to handle a wider range of product types, improving the versatility and applicability of the equipment and reducing the need to replace equipment or make extensive adjustments due to changes in product specifications.

[0044] Specifically, the round tube edge rolling machine also includes a flipping module 5 disposed on the frame 1. The flipping module 5 is located between the edge rolling module 3 and the loading and unloading module 2, so that the end of the rolled cylinder can be flipped to cooperate with the subsequent sleeve process. The flipping module 5 has a flipping plate 51 rotatably disposed on the frame 1, a first flipping driver 52 for driving the flipping plate 51 to rotate, a clamping component 53 reciprocatingly disposed on the flipping plate 51, and a second flipping driver 54 for driving the clamping component 53 to reciprocate. The second flipping driver 54 drives the clamping component 53 to approach the round tube and clamp and position it. Then the first flipping driver 52 drives the flipping plate 51 to flip the round tube positioned by the clamping component 53. The flipped round tube is then transferred to the subsequent sleeve process via the loading and unloading module 2.

[0045] In practical use, the flipping module 5 allows the rolled end of the round tube to be flipped to facilitate subsequent sleeve processing. This design ensures the continuity of the production process, enabling the round tube to smoothly enter the next process after rolling without additional manual adjustments or equipment changes. This reduces downtime during production, improves overall production efficiency, and ensures that products are processed according to the predetermined process flow. The first flipping driver 52 drives the flipping plate 51 to rotate, and the second flipping driver 54 drives the clamping assembly 53 to reciprocate, achieving automated flipping and clamping positioning of the round tube. This automated operation reduces manual intervention; workers no longer need to manually flip the rolled tube, significantly reducing labor intensity and minimizing errors and uncertainties that may arise from manual operation, thus improving production stability and reliability.

[0046] The clamping component 53 accurately approaches and clamps the round tube, and then the flipping plate 51, driven by the first flipping driver 52, precisely flips the round tube. This precise operation ensures that the angle of the round tube flipping is accurate, allowing the round tube to better fit with the sleeve in subsequent sleeve processes, improving the assembly accuracy and quality of the product, and reducing the scrap rate caused by inaccurate flipping. The reciprocating motion of the clamping component 53 and the rotation design of the flipping plate 51 in the flipping module 5 enable the module to adapt to the flipping requirements of round tubes of different specifications and sizes. By adjusting parameters such as the clamping position of the clamping component 53 and the rotation angle of the flipping plate 51, various round tubes can be effectively flipped, improving the versatility and flexibility of the equipment, expanding its application range, and meeting the production requirements of different customers and products.

[0047] Specifically, the flipping module 5 also has a flipping bracket 55 that is reciprocated on the frame 1, and a third flipping driver 56 for driving the flipping bracket 55 to reciprocate. The third flipping driver 56 drives the flipping bracket 55 to move closer to or away from the round tube on the loading and unloading module 2. The flipping plate 51 is reciprocated on the flipping bracket 55. The movement direction of the clamping component 53 is intersected with the movement direction of the flipping bracket 55.

[0048] In actual use, the third flipping driver 56 drives the flipping bracket 55 to reciprocate, allowing the flipping bracket 55 to move closer to or further away from the round tube on the loading / unloading module 2. This function allows the flipping module 5 to flexibly adjust its relative position to the round tube according to different production needs and the position of the round tube on the loading / unloading module 2. Whether it is a change in the size of the round tube or an adjustment in the layout of the loading / unloading module 2, the reciprocating motion of the flipping bracket 55 ensures that the flipping module 5 accurately operates the round tube, enhancing the adaptability of the equipment to different working conditions. The flipping plate 51 is reciprocated on the flipping bracket 55, and the movement direction of the clamping component 53 is intersected with the movement direction of the flipping bracket 55. This structural design gives the clamping component 53 higher freedom and accuracy when approaching and clamping the round tube. The clamping component 53 can be finely adjusted in different directions to accurately align and clamp the tube. At the same time, the reciprocating motion of the flipping plate 51 helps to better control the posture of the tube during the flipping process, improving the accuracy and stability of the entire flipping operation and reducing problems such as tube damage or positional deviation caused by inaccurate operation.

[0049] Through the coordinated movement of its components, the flipping bracket 55 approaches the circular tube, the clamping component 53 clamps it, and then the flipping plate 51 flips it over. The entire process is smooth and efficient. This optimized workflow reduces unnecessary operation steps and time waste, allowing the circular tube to be quickly transferred from the loading / unloading module 2 to the flipping position and completed before entering subsequent processes, thereby improving overall production efficiency and accelerating the production pace. This structural design with multiple reciprocating motion components allows the flipping module 5 to adapt to more types and specifications of circular tubes. Circular tubes of different sizes and shapes can be accurately flipped by adjusting the motion parameters of the flipping bracket 55, the flipping plate 51, and the clamping component 53. At the same time, this modular design also facilitates future upgrades and expansions of the equipment, such as adding more sensors or actuators to further improve the intelligence and automation of the flipping operation, enhancing the equipment's versatility and scalability.

[0050] Specifically, both the loading rack 211 and the unloading rack 221 are equipped with limiting components 23 for assisting in the conveying of round tubes. The limiting component 23 has a first locking member 231 rotatably mounted on the loading rack 211. A first adjusting rod 232 is rotatably mounted on the first locking member 231. A second locking member 233 is rotatably mounted on the first adjusting rod 232. A second adjusting rod 234 is rotatably mounted on the second locking member 233. A limiting plate 235 is provided at the end of the second adjusting rod 234. The position of the limiting plate 235 is adjusted by the adjusting rod. The length of the adjusting rod is adjusted by the locking member. The adjustment directions of the first adjusting rod 232 and the second adjusting rod 234 are arranged intersecting each other.

[0051] In actual use, the limiting component 23, through the combination of the first adjusting rod 232, the second adjusting rod 234, and the limiting plate 235, can precisely limit the position of the round tube during the conveying process. The position of the limiting plate 235 can be adjusted via the adjusting rods, and the adjustment directions of the first adjusting rod 232 and the second adjusting rod 234 are intersected, allowing the limiting plate 235 to constrain the round tube in multiple dimensions. This effectively prevents the round tube from shifting, rolling, or falling during the conveying process, improving the stability of the round tube conveying on the loading and unloading rack 221 and ensuring that the round tube can accurately enter the crimping module 3 or be conveyed to the next process. The length of the adjusting rods can be adjusted via the locking element. This design allows the limiting component 23 to be flexibly adjusted according to the different diameters, lengths, and other specifications of the round tube. Whether it is a smaller or larger round tube, the position of the limiting plate 235 can be changed by adjusting the length of the first adjusting rod 232 and the second adjusting rod 234, thereby adapting to the conveying needs of round tubes of different specifications, enhancing the versatility of the equipment, and reducing the need to replace or adjust the entire limiting device due to changes in the specifications of the round tube.

[0052] The limiting component 23 has a relatively simple structure; the position of the limiting plate 235 can be adjusted by rotating the adjusting rod and operating the locking mechanism. This operation method is simple and easy to understand, and operators can master it without complicated training. At the same time, the simple structure also makes equipment maintenance more convenient. When the limiting component 23 malfunctions or requires maintenance, it can be quickly and accurately repaired and adjusted, reducing maintenance costs and downtime, and improving equipment operating efficiency. Because the limiting component 23 ensures accurate and stable conveying of the round tube, it reduces the need for readjustment and processing due to inaccurate tube positioning, making the loading and unloading process smoother and improving the continuity of the production process. This helps to shorten the production cycle, improve overall production efficiency, and ensure that production tasks are completed on time and with high quality.

[0053] Specifically, the third drive assembly 35 has a drive motor 351 mounted on the frame 1. The output end of the drive motor 351 is provided with a helical gear 352. The support plate 31 is provided with a helical rack 353 that works with the helical gear 352. The drive motor 351 drives the helical gear 352 to drive the helical rack 353 to make the support plate 31 reciprocate. A sliding assembly 37 is also provided between the support plate 31 and the frame 1. The sliding assembly 37 works with the helical gear 352 and the helical rack 353 to make the support plate 31 slide back and forth.

[0054] In practical use, the drive motor 351 is used as the power source, providing stable and continuous power output. The engagement of the helical gear 352 and the helical rack 353 effectively converts the rotational motion of the motor into the linear reciprocating motion of the support plate 31. This transmission method has a large load-bearing capacity and can stably drive the movement of the support plate 31 and the inner mold assembly 321, outer mold assembly 322, and lubrication assembly 36 mounted on it, ensuring the stability and reliability of the position adjustment of each component during the entire hemming operation. The meshing transmission of the helical gear 352 and the helical rack 353 has high transmission accuracy, enabling precise control of the movement distance and position of the support plate 31. By controlling the rotation angle and number of revolutions of the drive motor 351, the moving position of the support plate 31 can be precisely adjusted, allowing the inner mold assembly 321, outer mold assembly 322, and lubrication assembly 36 to accurately reach the designated position on the round tube, providing precise positioning for subsequent hemming operations and improving the accuracy and quality of hemming.

[0055] During transmission, the helical gear 352 and helical rack 353 gradually engage and disengage, resulting in smoother transmission compared to spur gear transmission. This effectively reduces impact and vibration during movement. This not only improves the stability of the support plate 31's movement and protects the components mounted on it, extending their service life, but also reduces noise generated during equipment operation and improves the working environment. The sliding assembly 37 between the support plate 31 and the frame 1 provides good guidance and support during the reciprocating sliding of the support plate 31. Working in conjunction with the helical gear 352 and helical rack 353, it further enhances the stability of the support plate 31's movement, reduces potential swaying or deviation during movement, and ensures that the support plate 31 can accurately reciprocate along a predetermined trajectory, improving the reliability and accuracy of the equipment operation.

[0056] In this embodiment, the number of limiting components 23 is set to multiple, and the multiple limiting components 23 are arranged on the loading rack 211 and the unloading rack 221 along the loading and unloading direction.

[0057] In actual use, multiple limiting components 23 are arranged along the loading and unloading directions, enabling multi-point limiting of the round tube along its entire conveying path. This more effectively prevents the round tube from shifting, rolling, or shaking during conveying, ensuring that the round tube is always conveyed stably along the predetermined trajectory. Compared to a single limiting component 23, multiple limiting components 23 provide more comprehensive constraints, greatly improving the stability and reliability of the round tube conveying, ensuring that the round tube can accurately enter the crimping module 3 or be conveyed to the next process. For round tubes of different sizes, the multiple limiting components 23 can be flexibly adjusted and coordinated according to the actual size of the round tube.

[0058] Regardless of the length of the round tube, effective limiting and support can be achieved by appropriately setting the positions and states of different limiting components 23. This allows the loading and unloading rack 221 to adapt to various specifications of round tubes, enhancing the versatility and applicability of the equipment, expanding its application range, and reducing the need for frequent replacement or adjustment of limiting devices due to different tube sizes. A stable round tube conveying process reduces production interruptions and product quality issues caused by inaccurate tube positioning. Multiple limiting components 23 ensure accurate positioning and conveying of the round tube, allowing it to smoothly enter the crimping module 3 for processing, improving the continuity and efficiency of the production process. Simultaneously, accurate positioning also helps improve the precision and quality of crimping, reducing scrap rates and improving the overall product quality.

[0059] In this embodiment, the clamping component 43 clamps multiple round tubes simultaneously. The lubrication component 36 and the crimping mold 32 are respectively moved to two adjacent round tubes under the drive of the third driving component 35. The transport component 41 moves the round tubes lubricated by the lubrication component 36 to the bottom of the crimping mold 32 for crimping operation. At the same time, the lubrication component 36 lubricates the un-crewed round tubes.

[0060] In actual use, the clamping assembly 43 can clamp multiple round tubes simultaneously, and the lubrication assembly 36 and the crimping die 32 can operate on two adjacent round tubes respectively under the drive of the third drive assembly 35. This means that while the crimping die 32 is crimping one round tube, the lubrication assembly 36 can lubricate another round tube, realizing the parallelization of the production process, greatly shortening the processing cycle of a single round tube, and thus improving the overall production efficiency. The conveying assembly 41 can promptly transfer the lubricated round tube to the crimping die 32 for crimping, achieving seamless connection between the two key processes of lubrication and crimping, reducing the waiting time between processes, and further improving production efficiency.

[0061] Because the lubrication assembly 36 and the crimping die 32 process multiple round tubes sequentially according to a fixed process and method, each round tube can obtain a relatively consistent lubrication effect and crimping quality. This helps to ensure the stability and consistency of product quality and reduce quality fluctuations caused by human factors or operational differences. Throughout the entire processing, from clamping, lubrication, and handling of the round tubes to crimping, each step is carried out in an orderly manner under the automated control of the equipment, reducing manual intervention and lowering the labor intensity of workers.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
