Description

Technical Field

[0001] The utility model relates to the field of non-standard automated mechanical equipment, in particular to an automatic metal pipe rod threading machine. Background Art

[0002] In modern kitchenware manufacturing, metal mesh frames or baskets are widely used in kitchen appliances, cookware accessories, and other products due to their durability, ventilation, and breathability. To ensure the structural strength of the product, traditional manufacturing methods often use solid metal rods as the outer frame or support rods. However, while this design provides the necessary strength, it also comes with some significant disadvantages. Due to the high density of solid metal rods, using this material results in higher raw material costs. For large-scale kitchenware manufacturers, this not only increases the cost of each product but also reduces overall profit margins. The use of solid metal rods also increases the weight of the product, which not only affects its convenience but also makes transportation and installation inconvenient. For products that need to be moved frequently, an overly heavy design is clearly not the best choice.

[0003] In recent years, new design solutions have emerged in the industry to reduce costs while maintaining product performance. These include using a metal outer tube encased in a metal inner rod to form the outer frame or support rod. This design not only maintains the strength and stability of the metal rod, but also effectively reduces production costs by reducing material usage. Furthermore, the hollow structure helps reduce the overall weight of the product, making it more portable and easier to use.

[0004] However, this novel design presented a series of new challenges during production. Traditionally, workers manually inserted the metal inner rod into the metal outer tube and ensured a precise fit. Because both the outer tube and the inner rod are long and slender, maintaining stable alignment was difficult during manual operation, making the insertion process complex and time-consuming.

[0005] Specifically, the metal outer tube and metal inner rod are both slender components, requiring a high degree of precision during manual alignment. However, manual operation makes it difficult to ensure consistency in each step, which can easily lead to fluctuations in product quality due to human factors and increase the defective product rate. Any slight deviation can cause subsequent welding failures and increase the chance of rework. Furthermore, the manual alignment and insertion process is cumbersome and time-consuming, seriously affecting production efficiency and hindering mass production. Furthermore, traditional assembly line operations require multiple workers to work together, increasing labor costs. Furthermore, workers are prone to fatigue from performing repetitive and delicate operations for long periods of time, which in turn affects product quality.

[0006] In summary, in order to overcome the many problems existing in the existing technology, improve production efficiency and reduce production costs, it is necessary to develop an automated equipment that can achieve efficient and precise socketing of the metal outer tube and the metal inner rod.

[0025] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0026] For ease of description and understanding, please refer to the descriptions of the front, back, up, down, left, right, outside, inside and other positional relationships in this case. Figure 2 The orientation shown in .

[0027] like Figures 1 to 5As shown, this case provides an automatic metal tube rod threading machine, which specifically includes a frame 100. The frame 100 includes a mounting table 101, which is used to install the required components on the mounting table 101 to provide a support surface. A first feeding mechanism 1 and a first rolling mechanism 2 are installed on the mounting table 101. Among them, the first feeding mechanism 1 is responsible for the initial feeding of the metal inner rod 200 to ensure sufficient material supply for subsequent processes. The first rolling mechanism 2 is connected to the front end of the first feeding mechanism 1, and is used to transfer the metal inner rod 200 on the first feeding mechanism 1 to the first rolling mechanism 2, and then transfer it to the corresponding position through the first rolling mechanism 2 to ensure that the position of the metal inner rod 200 is accurate when the push rod mechanism 5 is started. The mounting table 101 also has a second feeding mechanism 3 located on the right side of the first feeding mechanism 1, a second rolling mechanism 4 connected to the front end of the second feeding mechanism 3, and a push rod mechanism 5 located at the front end of the first feeding mechanism 1. The second feeding mechanism 3 has similar structural features to the first feeding mechanism 1 and is primarily responsible for the initial feeding of the metal outer tube 300, ensuring sufficient material supply for subsequent processes. The push rod mechanism 5 is used to precisely push the corresponding metal inner rod 200 into the metal outer tube 300, achieving precise docking of the metal inner rod 200 and the metal outer tube 300. The metal inner rod 200 is placed on the first feeding mechanism 1, and the metal outer tube 300 is placed on the second feeding mechanism 3. The second rolling mechanism 4 is used to transfer the metal outer tube 300 from the second feeding mechanism 3 to the second rolling mechanism 3, and then to the corresponding position via the first rolling mechanism 2. The push rod mechanism 5 is used to push the metal inner rod 200 from the first rolling mechanism 2 into the metal outer tube 300 on the second rolling mechanism 4 at the corresponding position. A central control system 6 is also mounted on the mounting platform 101. In practice, the central control system generally consists of a computer control system, sensors, actuators, and other components, responsible for monitoring and controlling the operation of the entire automated equipment. This is well known to those skilled in the art and will not be elaborated upon here. It should be noted that, in the specific implementation, the corresponding positions referred to in the text are the metal inner rod 200 that is rolled down from the first feeding mechanism 1 and transferred to the end of the first rolling mechanism 2 and is ready for the plug-in operation, and the metal outer tube 300 that is rolled down from the second feeding mechanism 3 on the second rolling mechanism 4 and is transferred to the end of the second rolling mechanism 4 and is ready for the plug-in operation. The positions of these two are aligned with each other when plugging, which will be explained later.

[0028] It should be noted that, in practice, this invention employs multiple sensor switches to detect the presence or absence of an object and its placement, thereby triggering the device's actions or changing its state. This is well known in the art, and a detailed description of each sensor switch is omitted here. In practice, those skilled in the art may, based on common knowledge in the art and in conjunction with the present invention's automatic metal tube threading machine, configure the sensor switches to achieve linkage between the various mechanisms.

[0029] like Figure 1-Figure 3 As shown, specifically, the first loading mechanism 1 includes a symmetrically arranged first fixed bracket 11 and a first placement plate 12 symmetrically arranged on the inner side of the first fixed bracket 11. The first fixed bracket 11 is a symmetrically arranged frame structure, which is used to support and fix the first placement plate 12 to ensure the firmness and reliability of the first placement plate 12. The first placement plate 12 is used to place and transport the metal inner rod 200. In specific implementation, the first placement plate 12 is fixedly connected to the inner side wall of the first fixed bracket 11. The first placement plate 12 is tilted toward the first rolling mechanism 2 and its front end abuts against the first rolling mechanism 2. The tilted setting guides the metal inner rod 200 to slide into the first rolling mechanism 2. A first placement groove 13 is formed between the two first placement plates 12 to accommodate and position the metal inner rod 200.

[0030] Reference Figure 1 、 Figure 2 、 Figure 4 As shown, the second loading mechanism 3 includes a symmetrically arranged second fixed bracket 31 and a second storage plate 32 symmetrically arranged inside the second fixed bracket 31. The second storage plate 32 is fixedly connected to the inner sidewall of the second fixed bracket 31. The second storage plate 32 is tilted toward the second rolling mechanism 4, with its front end abutting the second rolling mechanism 4. A second storage slot 33 is formed between the two second storage plates 32. Because the first and second loading mechanisms 1 and 3 have similar structures and functions, the structural features, functions, and beneficial effects of the second loading mechanism 3 can be referred to the above description of the first loading mechanism 1. The difference is that the first loading mechanism 1 is used to place the metal inner rod 200, while the second loading mechanism 3 is used to place the metal outer tube 300. Due to the differences in size and shape of the metal inner rod 200 and the metal outer tube 300, the specific dimensions and configurations of the first and second loading mechanisms 1 and 3 may vary. However, the overall design principles are the same, so the common features between the two will not be discussed here. It should be noted that when dealing with metal inner rods 200 and metal outer tubes 300 of different lengths, the user can improve adaptability by adjusting the sizes of the first feeding mechanism 1 and the second feeding mechanism 3 .

[0031] like Figure 1-Figure 3As shown, specifically, the first rolling mechanism 2 includes a symmetrically arranged third fixed bracket 21 and a first loading roller 22 rotatably mounted on the third fixed bracket 21. The third fixed bracket 21 is used to support and fix the first loading roller 22 and other components, providing a stable support platform to ensure that the first loading roller 22 can rotate stably. The first rolling mechanism 2 also includes a first motor 23 for driving the first loading roller 22 to rotate and a receiving platform 24 connected to the front end of the first loading roller 22. A first positioning groove 241 is provided on the receiving platform 24, and a second positioning groove 211 is provided on the third fixed bracket 21. During specific implementation, the metal inner rod 200 is transferred from the first loading mechanism 1 to the first positioning groove 241 and the second positioning groove 211 through the rotation of the first loading roller 22, thereby ensuring the orderly transportation of the metal inner rod and improving the accuracy and efficiency of transportation. The receiving platform 24 is used to receive the metal inner rod 200 transferred from the front end of the first loading roller 22. The first motor 23 drives the first loading roller 22 to rotate, thereby transferring the metal inner rod 200 from the first loading mechanism 1 to the receiving platform 24, where it is ultimately locked into the first positioning slot 241 and the second positioning slot 211. The first positioning slot 241 and the second positioning slot 211 effectively position the ends of the metal inner rod 200, improving the positioning accuracy of the metal inner rod 200 and reducing deviation during transportation and the subsequent insertion of the metal inner rod 200 into the metal outer tube 300. It should be noted that the corresponding position of the metal inner rod 200 at this time is its position in the first positioning slot 241 and the second positioning slot 211. The first motor 24 is the power source for driving the first loading roller 22. It is connected to the first loading roller 22 via a first belt 231. The first belt 231 transmission connection reduces wear caused by direct drive. The first loading roller 22 is provided with a plurality of first receiving grooves 220 for accommodating the metal inner rods 200. The first receiving grooves 220 are grooves provided on the surface of the first loading roller 22 for accommodating and positioning the metal inner rods 200. They are designed according to the diameter of the metal inner rods 200 to ensure that the metal inner rods 200 can be stably placed in the first receiving grooves 220 and do not slip during rotation. Multiple first receiving grooves 220 can be provided as needed based on the circumference of the first loading roller 22 and the size of the metal inner rods 200 to ensure that the first loading roller 22 can accommodate enough metal inner rods 200 during rotation, thereby improving production efficiency. In specific implementation, the second positioning groove 211 and the first positioning groove 241 completely overlap after being extended horizontally. To facilitate production and installation and save materials, the second positioning groove 211 and the first positioning groove 241 can also be directly integrally formed and provided on the third fixed bracket 21 at both ends, which is more convenient to implement.

[0032] like Figure 1-Figure 3As shown, another embodiment of the first loading roller 22 in this case is designed to improve the versatility of the equipment by adjusting the position of the first auxiliary roller 222 to accommodate metal inner rods 200 of varying lengths. In this embodiment, the first loading roller 22 specifically comprises a first main roller 221 on the right side and a first auxiliary roller 222 on the left side. The first loading roller 22 is configured as a first main roller 221 and a first auxiliary roller 222, meaning both are provided with a first receiving groove 220. The first main roller 221 and the first auxiliary roller 222 are coaxially connected by a first connecting shaft 223 and rotate synchronously. Both ends of the first connecting shaft 223 are rotatably connected to the third fixing bracket 21. The first auxiliary roller 222 is detachably connected to the first connecting shaft 223, creating an adjustable space between the first main roller 221 and the first auxiliary roller 222. To adjust this adjustable space to accommodate metal inner rods 200 of varying lengths, the first auxiliary roller 222 is removed and loosened. After being loosened, it is slid onto the first connecting shaft 223 to the desired position and then secured. In practice, the first auxiliary roller 222 is secured to the first connecting shaft 223 via bolts. To further facilitate adjustment to accommodate metal inner rods 200 of varying lengths, a first slide rail 224 is mounted on the mounting platform 101, located below the first loading roller 22. Two symmetrical first slide rails 224 are provided, and a first base plate 225 is slidably connected to the first slide rail 224. In practice, a compatible structure can be provided at the lower end of the first base plate 225 to provide a direct sliding connection to the first slide rail 224. Alternatively, a slider can be fixedly connected to the first base plate 225, which is then slidably connected to the slide rail. The first motor 23 and the left third fixed bracket 21 are fixedly mounted on the first base plate 225. By mounting the left third fixed bracket 21 and the first motor 23 on the first base plate 225, after adjusting the position of the first auxiliary roller 222, the position of the first base plate 225 can be adjusted by sliding, thereby achieving synchronous adjustment of the left third fixed bracket 21 and the first motor 23, making adjustment convenient and quick. To facilitate the adjustment of the first base plate 225, a first adjustment mechanism 226 is connected to the lower end of the first base plate 225 for sliding or fixing the first base plate 225 relative to the first slide rail 224. In a specific implementation, the first adjustment mechanism 226 can be a manual screw adjustment mechanism commonly used in the field. This structure is simple and cost-effective. If the user needs to make adjustments frequently, he or she can also choose to set up an automatic adjustment mechanism as needed. The adjustment mechanism of this structure in this case only requires simple adjustments when processing products of different sizes, rather than replacing the entire equipment or a large number of parts, which greatly reduces downtime and conversion costs. The adjustment function enables the equipment to quickly adapt to changes in the production line in a short period of time, thereby improving the flexibility and response speed of the production line.

[0033] like Figure 1 、 Figure 2 、 Figure 4 As shown, the second roller mechanism 4 includes a symmetrically arranged fourth fixed bracket 41, a second loading roller 42 rotatably mounted on the fourth fixed bracket 41, and a second motor 43 for driving the second loading roller 42. The fourth fixed bracket 41 defines a third positioning slot 411 located at the front end of the second loading roller 42. The second loading roller 42 and the second motor 43 are connected via a second belt 431. The second loading roller 42 defines a plurality of second receiving slots 420 for accommodating the metal outer tubes 300. The second motor 43 drives the second loading roller 42 to rotate, thereby transferring the metal outer tubes 300 from the second loading mechanism 3 to the third positioning slots 411. Because the first and second roller mechanisms 2 and 4 have similar structures and functions, the structural features, functions, and beneficial effects of the second roller mechanism 4 can be referred to the above description of the first roller mechanism 2. The difference is that the first roller mechanism 2 is used to transfer the metal inner rods 200, while the second roller mechanism 4 is used to transfer the metal outer tubes 300. Due to the differences in size and shape between the metal inner rod 200 and the metal outer tube 300, the specific dimensions and configurations may vary, but the overall design principles are consistent, so the common parts of the two will not be repeated here. Another difference between the two is that the location and structure of the third positioning groove 411 are different from the first positioning groove 241 and the second positioning groove 211. Specifically, there are two third positioning grooves 411, which are respectively opened on the upper side walls of the two fourth fixing brackets 41. A pressing cylinder 45 is also installed on the fourth fixing bracket 41, located above the third positioning groove 411. The pressing cylinder 45 presses the metal outer tube 300 downward into the third positioning groove 411 to facilitate the passage of the metal inner rod 200 and its alignment and insertion with the metal outer tube 300. In practice, a through-hole is formed on the fourth fixing bracket 41, located near the third fixing bracket 21, for the metal inner rod 200 to pass through. The third positioning slot 411, the second positioning slot 211, the first positioning slot 241, and the through-hole are laterally aligned to ensure precise insertion of the metal inner rod 200 into the metal outer tube 300. It should be noted that the corresponding position of the metal outer tube 300 is the position within the third positioning slot 411.

[0034] like Figure 1 、 Figure 2 、 Figure 4As shown, as another embodiment of the second loading roller 42 in this case, in order to cooperate with another embodiment of the aforementioned first loading roller 22, the position of the second auxiliary roller 422 is adjusted to adapt to metal outer tubes 300 of different lengths, thereby improving the versatility of the equipment. In this embodiment, the second loading roller 42 includes a second main roller 421 on the left and a second auxiliary roller 422 on the right. The second main roller 421 and the second auxiliary roller 422 are coaxially connected and rotate synchronously via a second connecting shaft 423. The second auxiliary roller 422 is detachably connected to the second connecting shaft 423. The second connecting shaft 423 is rotatably connected to the fourth fixed bracket 41 at both ends. The mounting platform 101 is also equipped with a second slide rail 424 located below the second loading roller 42. The second slide rails 424 are symmetrically arranged, and a second base plate 425 is slidably connected to the second slide rail 424. The second motor 43 and the fourth fixed bracket 41 on the left are fixedly mounted on the second base plate 425. The lower end of the second base plate 425 is connected to a second adjustment mechanism 426 for sliding or fixing the second base plate 425 relative to the second slide rail 424. Since the first loading roller 22 and the second loading roller 42 have similar structures and functions, the structural features, functions, and beneficial effects of the second rolling mechanism 4 can be referred to the corresponding description of the first loading roller 22. The difference is that the first loading roller 22 is used to transport the metal inner rod 200, while the second loading roller 42 is used to transport the metal outer tube 300. Due to the differences in size and shape between the metal inner rod 200 and the metal outer tube 300, the specific dimensions and configurations of the first loading roller 22 and the second loading roller 42 may vary, but the overall design principles are the same, so the similarities between the two will not be repeated here.

[0035] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 As shown, the second roller mechanism 4 also includes a blanking module 44 connected to the front end of the second loading roller 42. The blanking module 44 includes a lifting cylinder 441 symmetrically mounted on the inner side wall of the fourth fixed bracket 41, and a guide column 442 connected to the front end of the fourth fixed bracket 41. A movable plate 443 is also movably mounted on the inner side wall of the fourth fixed bracket 41, located above the lifting cylinder 441. The front end of the movable plate 443 is tilted downward and is disposed below the third positioning slot 411. The guide column 442 is disposed at the front end of the third positioning slot 411 of the second loading roller 42, and the front end of the guide column 442 is tilted downward. During specific implementation, the lifting cylinder 441 presses the movable plate 443 upward, and the movable plate 443 moves upward to press the sleeved metal outer tube 300 so that it escapes from the third positioning grooves 411 on both sides. Then the sleeved metal outer tube 300 slides along the inclined movable plate 443 into the inclined guide column 442, and then slides downward along the guide column 442, so that the material is unloaded and passed to the next process, which makes unloading convenient.

[0036] Reference Figure 1 、 Figure 2 、 Figure 5 As shown, the push rod mechanism 5 includes a fifth fixed bracket 51, a support plate 52 mounted on the fifth fixed bracket 51, a push block assembly 53 slidably connected to the support plate 52, and a third motor 54 that drives the push block assembly 53 to slide back and forth along the support plate 52. In a specific embodiment, two fifth fixed brackets 51 are symmetrically provided to ensure stable installation. The fixed bracket 51 is used to connect and fix the support plate 52. The support plate 52 is used to connect the push block assembly 53 and fix the third slide rail 55 and the screw rod 56, ensuring stable installation of the third slide rail 55 and the screw rod 56 and smooth sliding of the push block assembly 53. The third slide rail 55 is mounted on the support plate 52, and the push block assembly 53 is slidably connected to the third slide rail 55. A screw rod 56 is also mounted on the support plate 52, located between the two third slide rails 55. One end of the screw rod 56 is connected to the third motor 54, and the other end extends laterally through a fixing seat 57 and is fixed to the end of the first slide rail 224. During specific implementation, the third motor 54 drives the screw rod 56 to rotate, and the rotation of the screw rod 56 drives the push block assembly 53 to slide back and forth along the third slide rail 55, ensuring the precise reciprocating motion of the push block assembly 53 and improving the insertion accuracy. The push block assembly 53 includes a downwardly disposed push tube head 531 for pushing the metal inner rod 200 to the right. During specific implementation, except for the push tube head 531 at the lower end of the push block assembly 53, the remaining structures can adopt a sliding push block structure common in the art. Preferably, the push tube head 521 is in the shape of a vertical hook. It should be noted that in order to make the push tube head 531 push the metal inner rod 200 quickly and accurately, the front end diameter of the push tube head 531 is larger than the diameter of the metal inner rod.

[0037] The following is a description of the working principle of this case in combination with the full text:

[0038] The operator places the metal inner rod 200 in the first placement groove 13 on the first placement plate 12 of the first feeding mechanism 1. Since the first placement plate 12 is tilted toward the first rolling mechanism 2, the metal inner rod 200 slides to the first rolling mechanism 2 under the action of gravity. The first motor 23 drives the first feeding roller 22 to rotate through the first belt 231, and the metal inner rod 200 enters the first receiving groove 220 on the first feeding roller 22. As the first feeding roller 22 rotates, the metal inner rod 200 falls into the first positioning groove 241 on the receiving platform 24 and the second positioning groove 211 on the third fixed bracket 21, completing the positioning.

[0039] At the same time, the operator places the metal outer tube 300 into the second storage slot 33 on the second storage plate 32 of the second loading mechanism 3. Because the second storage plate 32 is tilted toward the second roller mechanism 4, the metal outer tube 300 slides onto the second roller mechanism 4 under the action of gravity. The second motor 43 drives the second loading roller 42 via the second belt 431. The metal outer tube 300 enters the second receiving slot 420 of the second loading roller 42. As the second loading roller 42 rotates, the metal outer tube 300 falls into the third positioning slot 411 of the fourth fixing bracket 41. The pressing cylinder 45 then presses down to compress the metal outer tube 300 into position.

[0040] Finally, the third motor 54 rotates the screw rod 56, causing the push block assembly 53 to slide rightward along the third slide rail 55. The push head 531 on the push block assembly 53 pushes the metal inner rod 200 rightward until it is pushed into the already positioned metal outer tube 300. The lifting cylinder 441 then pushes the movable plate 443 upward, lifting the metal outer tube 300 out of the third positioning slot 411. The metal outer tube 300 then slides down the movable plate 443 under the action of gravity and then down the guide post 442 to the next process.

[0041] When the equipment needs to be adjusted to accommodate metal inner rods 200 of varying lengths, first loosen the bolts securing the first auxiliary roller 222 to the first connecting shaft 223 and adjust the position of the first auxiliary roller 222 relative to the first main roller 221. After adjustment, re-tighten the bolts on the first auxiliary roller 222. The first adjustment mechanism 226 at the lower end of the first base plate 225 adjusts the position of the first motor 23 and the third fixing bracket 21 on the left side to ensure smooth operation of the first rolling mechanism 2. The second rolling mechanism 4 can then be adjusted accordingly.

[0042] As mentioned above, this case protects an automatic metal tube rod threading machine, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
