Description

Technical Field

[0001] This utility model relates to the field of stainless steel flue processing technology, and more specifically, to an automatic processing device for precision steel pipes. Background Technology

[0002] Stainless steel flue pipes are primarily made from stainless steel plates with a thickness of approximately 0.8mm-1mm. During processing, a precision straightening device is used to straighten the pipe, ensuring high dimensional accuracy of both the inner and outer diameters at all points, hence the name "precision stainless steel flue pipe." For ease of transport, these pipes are cut into lengths no longer than one meter. Multiple sections are then connected using a socket-and-insert method (one section inserted into another). Because this method is used, one end of each section needs to be flared for easy insertion. Simultaneously, the other end is rolled inwards to eliminate sharp edges, improving safety. This inward rolling acts as a reinforcing rib at the pipe opening, enhancing rigidity and resistance to deformation, and facilitating insertion with the flared end of another section. Finally, each section is marked on its outer surface using a marking machine.

[0003] The existing flaring equipment, inner edge rolling equipment, and marking machine are all separate devices, not integrated together. Therefore, each device requires a separate operator. When flaring, inner edge rolling, and marking precision stainless steel cigarette tubes, operators must first transfer the cut cigarette tubes to the flaring equipment via a transfer box and manually load and unload them to flare the tubes. The flared cigarette tubes are then transferred to the inner edge rolling equipment via a transfer box, and manually loaded and unloaded again to perform inner edge rolling. Finally, the inner edge rolled cigarette tubes are transferred to the marking machine via a transfer box for marking. This results in high labor costs and increases the workload of the operators. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides an automatic precision steel pipe processing device, comprising a conveyor, a flaring mechanism, an inner edge-rolling mechanism, a laser marking machine, and a steel pipe transfer mechanism, all integrated on the same base and arranged at intervals. The conveyor is located on one side of the base and is used to transport cut steel pipes. The flaring mechanism, the inner edge-rolling mechanism, and the laser marking machine are all equipped with supporting fixtures for horizontally placing the steel pipes. When the steel pipes are placed on the supporting fixtures, both ends of the steel pipes are suspended in the air. The flaring mechanism is adapted to clamp the steel pipe and flare one end of the steel pipe; the inward rolling mechanism is adapted to clamp the flared steel pipe and inward roll the other end of the steel pipe; the laser marking machine is adapted to mark the steel pipe after inward rolling; the steel pipe transfer mechanism is adapted to transfer the steel pipe located at the tail of the conveyor to the flaring mechanism, and at the same time, transfer the flared steel pipe at the flaring mechanism to the inward rolling mechanism, and transfer the inward rolled steel pipe at the inward rolling mechanism to the laser marking machine.

[0005] Optionally, the supporting fixture includes a fixed base plate and a support plate. The fixed base plate is fixedly installed on the top of the base platform, and the support plate is installed on the top of the fixed base plate to support the steel pipe. Two support plates are installed at intervals on the fixed base plate. Each support plate has a placement groove for positioning the steel pipe, and both ends of the steel pipe protrude from the corresponding support plate in a cantilevered state.

[0006] Optionally, the flaring mechanism includes a first clamping component and a flaring component. The first clamping component and the flaring component are respectively located at both ends of the steel pipe on the corresponding support fixture. The flaring component is slidably disposed on the base and is adapted to be inserted into the steel pipe for flaring. The first clamping component can cooperate with the flaring component to clamp the steel pipe.

[0007] Optionally, the inward curling mechanism includes a second clamping component and an inward curling die. The second clamping component and the inward curling die are respectively located at both ends of the steel pipe corresponding to the supporting fixture. A stamping cylinder is fixedly connected to the end of the inward curling die away from the steel pipe. The stamping cylinder is fixedly connected to the base. The stamping cylinder is adapted to drive the inward curling die to be sleeved on the end of the steel pipe and cooperate with the second clamping component to clamp the steel pipe so as to stamp an inward curl at the end of the steel pipe.

[0008] Optionally, the steel pipe transfer mechanism includes a frame, a linear module, a movable plate, and a lifting and clamping assembly. The frame is fixedly installed on the top of the base. The linear module is installed on the frame and located above the flaring mechanism and the inner edge rolling mechanism. The linear module is connected to the movable plate to drive the movable plate to reciprocate. The lifting and clamping assembly is connected to the movable plate and moves synchronously to clamp and transfer the steel pipe. Three sets of lifting and clamping assemblies are spaced apart on the movable plate along the sliding direction of the movable plate to realize the synchronous transfer of steel pipes at the tail of the conveyor, the flaring mechanism, and the inner edge rolling mechanism.

[0009] Optionally, the flaring assembly includes a reduction gearbox, a pushing cylinder, and a flaring die. The reduction gearbox is slidably mounted on the top of the base. A gear set is provided inside the reduction gearbox. A servo motor that drives the gear set to rotate is fixedly connected to the reduction gearbox. A rack is slidably mounted inside the reduction gearbox. The rack meshes with the gear set to achieve movement. One end of the flaring die is fixedly connected to the rack, and the other end protrudes from the reduction gearbox to be suitable for insertion into the steel pipe. The pushing cylinder is fixed to the base to drive the reduction gearbox to move so that the flaring die is inserted into the steel pipe.

[0010] Optionally, the inner edge rolling die head has an edge rolling cavity on the side near the steel pipe. The end of the steel pipe is inserted into the edge rolling cavity through the stamping cylinder and deforms and rolls inward under the action of the edge rolling cavity to form an inner edge.

[0011] Optionally, the precision steel pipe automatic processing device also includes a lifting and unloading assembly installed on the base. A collection basket is placed on one side of the base. The lifting and unloading assembly includes a lifting cylinder and a lifting rod. The lifting rod is located below the steel pipe at the laser marking machine. The lifting cylinder is connected to the lifting rod to lift the marked steel pipe from the corresponding support fixture and make the steel pipe automatically roll into the collection basket.

[0012] Optionally, the lifting rod is inclined, and the distance from the end of the lifting rod near the collection basket to the top of the base is less than the distance from the end of the lifting rod near the lifting cylinder to the top of the base.

[0013] Optionally, the precision steel pipe automatic processing device further includes a steel pipe discharge mechanism located at the tail of the conveyor. The steel pipe discharge mechanism includes a discharge frame, a feeding component, and a blocking component. The discharge frame is inclined between the flaring mechanism and the conveyor, and the height of the end of the discharge frame near the flaring mechanism is lower than the height of the end of the discharge frame near the conveyor. The feeding component is connected to the conveyor and is used to push the steel pipes onto the discharge frame for discharge. The blocking component is installed on the discharge frame and is used to make the steel pipes on the discharge frame roll one by one to the side near the flaring mechanism so that the steel pipe transfer mechanism can accurately grasp them.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1. The flaring mechanism, inner edge rolling mechanism, and laser marking machine are all located on one base platform. The conveyor can automatically transport the cut steel pipes, and the steel pipe transfer mechanism can automatically and synchronously move and transfer the steel pipes processed on the conveyor and each mechanism. The entire device only requires one person to observe the operation from time to time, which reduces labor costs and alleviates the labor intensity of the staff.

[0016] 2. When the flaring die is flaring, the reduction gearbox can strengthen the driving force on the flaring die, so that the flaring die has sufficient power when flaring. At the same time, the servo motor and the reduction gearbox can improve the flaring accuracy of the flaring die, so that the steel pipe is flared with higher precision.

[0017] 3. The lifting and unloading assembly can lift the marked steel pipes from the corresponding support fixtures. The steel pipes will automatically roll into the collection basket due to the tilt of the lifting rod, realizing automatic unloading and further reducing the labor intensity of the workers.

[0018] 4. Since the moving distance of the steel pipe transfer mechanism is a fixed value when transferring steel pipes, and the steel pipes are circular, they will roll during the conveyor process. This results in different positions of each steel pipe when it is transported to the tail of the conveyor, making it inconvenient for the steel pipe transfer mechanism to directly grab the steel pipes from the conveyor. Therefore, the steel pipes transported to the tail of the conveyor will be pushed onto the discharge rack by the unloading component. The inclined discharge rack can make the steel pipes roll automatically. Under the action of the baffle component, the steel pipes roll down one by one intermittently to a fixed position near the flaring mechanism of the discharge rack. This achieves automatic unloading and ensures the accuracy of the steel pipe transfer mechanism in grabbing and transferring the steel pipes. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-8 This application will be described in further detail.

[0029] Reference Figure 1The processed steel pipe has a flared end and an inwardly rolled edge end. The outer diameter of the flared end is larger than the outer diameter of the inwardly rolled edge end. The inwardly rolled edge end is formed by bending inwards into the steel pipe to create a ring-shaped rolled edge. In this embodiment, the preferred thickness of the steel pipe is 0.8mm, which makes the pipe less prone to deformation and lighter in weight.

[0030] This utility model provides an automatic precision steel pipe processing device, referring to... Figures 1 to 3 The precision steel pipe automatic processing device includes a conveyor 1, a steel pipe discharge mechanism 2, a flaring mechanism 3 integrated on the top of the same base and arranged at intervals, an inner edge rolling mechanism 4, a laser marking machine 5, a steel pipe transfer mechanism 6, and a lifting and unloading assembly 7 installed on the base. The conveyor 1 is located on one side of the base and is used to transport the cut steel pipes. The steel pipe discharge mechanism 2 is located at the tail of the conveyor 1 (the end of the conveying direction of the conveyor 1) and is used to discharge the steel pipes, causing them to intermittently roll one by one to a fixed position. The flaring mechanism 3, the inner edge rolling mechanism 4, and the laser marking machine 5 are all equipped with support fixtures 8 for horizontally placing the steel pipes. When the steel pipe is placed on the support fixtures 8, both ends of the steel pipe are suspended. The flaring mechanism 3 is suitable for clamping the steel pipe and flaring one end of the steel pipe; the inner edge rolling mechanism 4 is suitable for clamping the flared steel pipe and inner-rolling the other end of the steel pipe; the laser marking machine 5 is suitable for marking the inner-rolled steel pipe. The steel pipe transfer mechanism 6 is suitable for transferring the steel pipes that have rolled to a fixed position on the steel pipe discharge mechanism 2 to the flaring mechanism 3. At the same time, it transfers the flared steel pipes at the flaring mechanism 3 to the inner edge rolling mechanism 4, and the inner edge rolling mechanism 4 transfers the inner edge rolling steel pipes to the laser marking machine 5. A collection basket is placed on one side of the base. The lifting and unloading assembly 7 can lift the marked steel pipes from the corresponding support fixture 8 and make the steel pipes automatically roll into the collection basket.

[0031] Reference Figures 1 to 3 The steel pipe discharge mechanism 2 includes a discharge frame 21, a feeding assembly 22, and a blocking assembly. The discharge frame 21 is inclined between the flaring mechanism 3 and the conveyor 1, with the height of the end of the discharge frame 21 near the flaring mechanism 3 being lower than the height of the end of the discharge frame 21 near the conveyor 1. The feeding assembly 22 is connected to the conveyor 1 and is used to push the steel pipes onto the discharge frame 21 for discharge. The blocking assembly is installed on the discharge frame 21 and is used to make the steel pipes on the discharge frame 21 roll one by one to the side near the flaring mechanism 3 so that the steel pipe transfer mechanism 6 can accurately grasp them.

[0032] One end of the discharge rack 21 is bolted to the conveyor 1. A support steel plate is bolted to the top of the base near the conveyor 1, extending to the bottom of the discharge rack 21 and bolted to it, thus supporting the discharge rack 21. The discharge rack 21 is relatively lightweight, and the number of steel pipes discharged on it is limited, so the support steel plate will not bend.

[0033] The top of the feeding rack 21 is equipped with a feeding trough, in which the steel pipes are placed, so that the steel pipes will not experience significant axial movement. The feeding rack 21 has an opening on the side near the base, which communicates with the feeding trough, so that the steel pipe transfer mechanism 6 can grab a steel pipe located at the end of the feeding rack 21 near the base.

[0034] Reference Figures 1 to 3 An extension frame 11 is bolted to the conveyor 1, extending upwards. A feeding assembly 22 is mounted on the extension frame 11 and is located above the discharge frame 21 and the conveyor 1. The feeding assembly 22 includes a feeding cylinder 24 and a lever 25. The cylinder body of the feeding cylinder 24 is fixedly connected to the extension frame 11 by bolts. The lever 25 is bolted to the telescopic rod of the feeding cylinder 24. When the feeding cylinder 24 drives the telescopic rod to retract, the lever 25 can move the steel pipe located at the tail of the conveyor 1 into the discharge trough on the discharge frame 21. Then, the feeding cylinder 24 drives the telescopic rod to extend and reset the lever, so that the next steel pipe can be moved into the discharge trough on the discharge frame 21.

[0035] The material blocking assembly includes two sets of material blocking cylinders 23, both located at the top of the discharge frame 21, and arranged at intervals along the axial direction of the steel pipe. Each set of material blocking cylinders 23 includes two cylinders 23, arranged at intervals along the direction in which the steel pipe rolls on the discharge frame 21, and connected to the discharge frame 21 by bolts. When the telescopic rods of the two material blocking cylinders 23 extend, they block the rolling of the steel pipe. There is space between the telescopic rods of the two material blocking cylinders 23 for placing one steel pipe. Thus, when the telescopic rod of the material blocking cylinder 23 near the base retracts, the steel pipe between the two material blocking cylinders 23 rolls to the end of the discharge frame 21 near the base and is stopped. At this time, the telescopic rod of the material blocking cylinder 23 near the conveyor 1 is extended, blocking the rolling of the remaining steel pipes. Then, the telescopic rod of the material-blocking cylinder 23 near the base extends, and the telescopic rod of the material-blocking cylinder 23 away from the base retracts, causing a steel pipe to roll down between the two material-blocking cylinders 23. Then, the telescopic rod of the material-blocking cylinder 23 away from the base extends to block the remaining steel pipes. This cycle is repeated to achieve the rolling and unloading of steel pipes one by one.

[0036] Reference Figures 1 to 5The three supporting fixtures 8 have the same structure; the following description uses one supporting fixture 8 as an example. The supporting fixture 8 includes a fixed base plate 81 and supporting plates 82. The fixed base plate 81 is fixedly installed on the top of the base platform with bolts. Two supporting plates 82 are symmetrically spaced on the fixed base plate 81, and both supporting plates 82 are bolted to the top of the fixed base plate 81 to support the steel pipe. Each supporting plate 82 has a placement groove for positioning the steel pipe. In this example, the placement groove is preferably a V-shaped groove. The steel pipe is placed in two placement grooves, but both ends of the steel pipe protrude from the corresponding supporting plate 82 in a cantilevered state to facilitate processing of the ends of the steel pipe. When the steel pipe transfer mechanism 6 transfers the steel pipe, it transfers the steel pipe to the corresponding supporting plate 82.

[0037] Reference Figures 1 to 5 The flaring mechanism 3 includes a first clamping component 31 and a flaring component 32. The first clamping component 31 and the flaring component 32 are respectively located at both ends of the steel pipe on the corresponding support fixture 8. The flaring component 32 is slidably mounted on the base and is suitable for being inserted into the steel pipe for flaring. The first clamping component 31 can cooperate with the flaring component 32 to clamp the steel pipe.

[0038] Reference Figures 1 to 6 The first clamping assembly 31 includes a first fixed seat, a first clamping cylinder 33, and a first clamping plate 34. The first fixed seat is bolted to the top of the base. The cylinder body of the first clamping cylinder 33 is fixedly connected to the first fixed seat by bolts. The first clamping plate 34 is bolted to the telescopic rod of the first clamping cylinder 33. The first clamping cylinder 33 drives the first clamping plate 34 to move closer to the steel pipe. At the same time, the flaring assembly 32 also moves closer to the steel pipe, thereby causing one end of the steel pipe to clamp against the first clamping plate 34 and the other end to clamp against the flaring assembly 32.

[0039] The flaring assembly 32 includes a reduction gearbox 35, a pushing cylinder 36, and a flaring die 37. The reduction gearbox 35 is slidably mounted on the top of the base. A gear set is located inside the reduction gearbox 35, and a servo motor 38, which drives the gear set, is bolted to the top of the reduction gearbox 35. A rack 39 is slidably mounted inside the reduction gearbox 35, meshing with the output gear in the gear set to achieve movement. One end of the flaring die 37 is slidably inserted inside the reduction gearbox 35, while the other end protrudes from the reduction gearbox 35 and is exposed to the outside for insertion into the steel pipe. The rack 39 is fixedly connected to the flaring die 37 by bolts. Thus, when the flaring die 37 flares, the reduction gearbox 35 strengthens the pushing force on the flaring die 37, providing sufficient power for flaring. Simultaneously, the servo motor 38, in conjunction with the reduction gearbox 35, improves the flaring accuracy of the flaring die 37, resulting in higher precision after flaring the steel pipe. The push cylinder 36 is located on the side of the reduction gearbox 35 near the inner edge rolling mechanism 4. The cylinder body of the push cylinder 36 is fixedly connected to the base by bolts, and the telescopic rod of the push cylinder 36 is fixedly connected to the reduction gearbox 35 by bolts. In this way, the push cylinder 36 will push the reduction gearbox 35 to move closer to or away from the steel pipe, so that the flaring die 37 is inserted into the steel pipe to flare the steel pipe, and after flaring is completed, it is pulled out from the steel pipe.

[0040] Reference Figures 1 to 6 The flaring die 37 includes an integrally formed insertion section and a flaring section. The outer diameter of the insertion section is smaller than the inner diameter of the steel pipe before flaring, so as to facilitate precise insertion into the steel pipe. The flaring section is located at the end of the insertion section away from the steel pipe, and the outer diameter of the flaring section is 2mm larger than the inner diameter of the steel pipe before flaring. The flaring section and the insertion section are provided with a transition slope, so that the flaring section can be smoothly inserted into the steel pipe, and the steel pipe is flared by the thrust applied to the rack 39 by the reduction gearbox 35.

[0041] Reference Figures 1 to 7The inner edge rolling mechanism 4 includes a second clamping component 41 and an inner edge rolling die 42. The second clamping component 41 and the inner edge rolling die 42 are located at the two ends of the steel pipe on the corresponding support fixture 8, respectively. The second clamping component 41 is located at the end of the steel pipe after the flare. The second clamping component 41 includes a second fixed seat, a second clamping cylinder 43, and a second clamping plate 44. The second fixed seat is bolted to the top of the base. The cylinder body of the second clamping cylinder 43 is fixedly connected to the second fixed seat by bolts. The second clamping plate 44 is bolted to the telescopic rod of the second clamping cylinder 43. The second clamping cylinder 43 drives the second clamping plate 44 to move closer to the steel pipe. A stamping cylinder 45 is fixedly connected to the end of the inner edge rolling die 42 away from the steel pipe. The stamping cylinder 45 is fixedly connected to the base and can drive the inner edge rolling die 42 to move closer to the steel pipe and fit onto the end of the steel pipe. The curling die head and the second clamping plate 44 move synchronously to clamp the steel pipe. However, after clamping the steel pipe, the stamping cylinder 45 continues to drive the inner curling die head 42 to move so as to stamp out the inner curl at the end of the steel pipe.

[0042] Reference Figures 1 to 7 The inner edge rolling die head 42 has an edge rolling die cavity 421 on the side near the steel pipe (existing technology in this field, the specific structure will not be described in detail). After the steel pipe is inserted into the edge rolling die cavity 421, the stamping cylinder 45 continues to apply a pushing force to the steel pipe. The end of the steel pipe will shrink inward and bend and roll up under the action of the edge rolling die cavity 421 structure to form an inner edge.

[0043] The laser marking machine 5 (existing technology, detailed structure will not be described in detail) is fixed to the top of the base with bolts. The laser head of the laser marking machine 5 is located at the top of the flared end of the steel pipe, so it will mark the outer wall of the flared end of the steel pipe.

[0044] Reference Figures 1 to 7 The lifting and unloading assembly 7 includes a lifting cylinder 71 and lifting rods 72. The cylinder body of the lifting cylinder 71 is bolted to the bottom of the base plate, and the telescopic rod of the lifting cylinder 71 passes through the base and is located at the top of the base. A lifting block 73 is bolted to the telescopic rod of the lifting cylinder 71, and a crossbar 74 passes through the lifting block 73. The length direction of the crossbar 74 is consistent with the axial direction of the steel pipe, and the crossbar 74 is fixedly connected to the lifting block 73 by set bolts and rises and falls synchronously. Two lifting rods 72 are spaced apart and located between the two support plates 82 of the laser marking machine 5. Both lifting rods 72 are welded to the crossbar 74, and the lifting rods 72 are located below the steel pipe at the laser marking machine 5. When the lifting cylinder 71 drives the lifting block 73 to rise, it will drive the crossbar 74 and the lifting rods 72 to rise synchronously, thereby lifting the steel pipe off the support plate 82. The lifting rod 72 is set at an angle, and the distance from the end of the lifting rod 72 near the collection basket to the top of the base is less than the distance from the end of the lifting rod 72 near the lifting cylinder 71 to the top of the base. In this way, the steel pipe that is lifted will automatically roll down.

[0045] A flexible guide plate is installed at an angle on the base. The steel pipes lifted by the lifting rod 72 will roll onto the flexible guide plate and then roll into the collection basket. In this embodiment, the flexible guide plate is preferably made of cardboard. The bottom of the collection basket is relatively low from the top of the base, and three layers of steel pipes can be stacked inside the collection basket. Because the steel pipes themselves have a certain strength and are relatively light, they are unlikely to cause dents to the existing steel pipes in the collection basket after falling into it, and they themselves will not be damaged.

[0046] Reference Figures 1 to 5 The steel pipe transfer mechanism 6 includes a frame 61, a linear module 62 (existing technology, common knowledge in the field, specific structure not described in detail), a moving plate 63, and a lifting and clamping assembly 64. The frame 61 is fixedly installed on the top of the base by bolts. The linear module 62 is located above the flaring mechanism 3 and the inner edge rolling mechanism 4, and is fixedly connected to the frame 61 by bolts. The moving plate 63 is fixedly connected to the sliding part of the linear module 62 by bolts, so that the linear module 62 can drive the moving plate 63 to move closer to or away from the conveyor 1. The lifting and clamping assembly 64 is connected to the moving plate 63 and moves synchronously to clamp and transfer the steel pipes. Three sets of lifting and clamping assemblies 64 are arranged at intervals on the moving plate 63 along the sliding direction of the moving plate 63 to realize the synchronous transfer of steel pipes on the discharge rack 21 and the supporting fixtures 8 at the flaring mechanism 3 and the inner edge rolling mechanism 4.

[0047] Reference Figures 1 to 5 Specifically, the lifting and clamping assembly 64 includes a lifting cylinder 65 and a clamping cylinder 66. The cylinder body of the lifting cylinder 65 is fixedly connected to the moving plate 63 by bolts; the telescopic rod of the lifting cylinder 65 faces downward and is fixedly mounted with an mounting plate. The cylinder body of the clamping cylinder 66 is fixedly connected to the mounting plate by bolts. Each of the two grippers of the clamping cylinder 66 has a clamping plate adapted to the steel pipe mounted on it by bolts, thus clamping the steel pipe without causing it to dent. After the clamping cylinder 66 clamps the steel pipe, the lifting cylinder 65 drives the clamping cylinder 66 to lift the steel pipe. Then, the linear module 62 drives the moving plate 63 to move the lifting cylinder 65 and the steel pipe for transfer.

[0048] When one of the clamping cylinders 66 clamps the steel pipe located on the discharge rack 21, the second clamping cylinder 66 clamps the steel pipe located on the support fixture 8 at the flaring mechanism 3; the third clamping cylinder 66 clamps the steel pipe located on the support fixture 8 at the inner edge rolling mechanism 4, then drives the steel pipe to rise and move away from the conveyor 1, then drives the steel pipe to fall, so that the steel pipe on the discharge rack 21 is located on the support fixture 8 at the flaring mechanism 3; the steel pipe originally located on the support fixture 8 at the flaring mechanism 3 is now located on the support fixture 8 at the inner edge rolling mechanism 4; the steel pipe originally located on the support fixture 8 at the inner edge rolling mechanism 4 is now located on the support fixture 8 at the marking machine, and so on.

[0049] The implementation principle of the precision steel pipe automatic processing device in this application embodiment is as follows: The conveyor 1 can automatically transport the cut steel pipes. The steel pipes transported to the tail of the conveyor 1 are pushed onto the discharge rack 21 by the unloading component 22. The inclined discharge rack 21 can make the steel pipes roll automatically. Under the action of the baffle component, the steel pipes roll down one by one to a fixed position near the flaring mechanism 3 on the discharge rack 21. The linear module 62 drives the moving plate 63 to move, thereby transferring the steel pipes on the discharge rack 21 and at the flaring mechanism 3 and the inner edge rolling mechanism 4. The flaring mechanism 3 is suitable for clamping the steel pipe and flaring one end of the steel pipe; the inner edge rolling mechanism 4 is suitable for clamping the flared steel pipe and inner edge rolling the other end of the steel pipe; the laser marking machine 5 is suitable for marking the steel pipe after inner edge rolling. The lifting and unloading assembly 7 can lift the marked steel pipe from the corresponding support fixture 8. The steel pipe will automatically roll into the collection basket due to the tilt of the lifting rod 72, thus realizing automatic unloading.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0053] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] It should be noted that when a component is referred to as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected to another component," it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as through socketing, snap-fitting, integral molding, welding, etc., which are achievable in conventional technologies and will not be elaborated upon here.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
