Description

Technical Field

[0001] This application relates to the field of pipe processing equipment, and in particular to a fully automated tapering system. Background Technology

[0002] Pipe end tapering is a technique that processes one end of a steel pipe into a tapered shape through a specific process. The principle is to use the plastic deformation characteristics of steel pipe material and mechanical principles to compress and deform the end of the steel pipe. This process is commonly used in scenarios that require connection, insertion, or sealing, such as pipeline systems, machinery manufacturing, and building structures.

[0003] Traditional steel pipe tapering mainly relies on manual operation of hydraulic presses or semi-automatic spinning equipment. However, steel pipes are usually long and heavy, and the process of manually transferring the steel pipes to the hydraulic press or semi-automatic spinning equipment is cumbersome and labor-intensive, ultimately resulting in low processing efficiency and shortcomings. Utility Model Content

[0004] In order to improve the problems existing in the traditional steel pipe tapering process, this application provides a fully automated tapering system.

[0005] The fully automated tapering system provided in this application adopts the following technical solution: A fully automated tapering system includes a material rack, a preheating platform, and a tapering platform arranged sequentially. A tapering mold is mounted on the tapering platform. Several pipes are stacked on the material rack, which is equipped with a feeding component for sequentially conveying the pipes to the preheating platform. A high-frequency heating coil, electrically connected to a control system, is slidably mounted on the preheating platform and is used to fit over the end of the pipe. A material transfer component and a coil transfer component are mounted on the preheating platform. The material transfer component conveys the pipes from the preheating platform to the tapering platform, and the coil transfer component drives the high-frequency heating coil to reciprocate. A tapering frame is slidably mounted on the tapering platform, and a clamping assembly is mounted on the tapering frame. A push-retracting component is mounted on the tapering platform. The clamping assembly secures the pipes, and the push-retracting component drives the tapering frame closer to or further away from the tapering mold.

[0006] By adopting the above technical solution, workers use hoisting equipment to stack pipes on a material rack. The loading component transports the pipes on the material rack to the preheating platform. The coil transfer component drives a high-frequency heating coil to be fitted onto the end of the pipe for rapid heating. Then, the material transfer component transports the heated pipe to a tapering platform. After the clamping assembly fixes the heated pipe, the tapering component pushes the heated end of the pipe close to the tapering mold. The tapering mold tapes the end of the pipe. Finally, the tapered pipe is transported away by the transfer equipment. In this process, there is no need for workers to operate hydraulic presses or semi-automatic spinning equipment, which greatly improves the processing efficiency of pipes.

[0007] Optionally, the material rack is provided with baffles on both sides along the axial direction of the pipe. The feeding component includes multiple inclined guide rods disposed between the two baffles. The multiple inclined guide rods are arranged along the axial direction of the pipe. A lifting plate is vertically slidably disposed on the baffle of the material rack near the preheating platform. The upper surface of the lifting plate is inclined towards the preheating platform in a downward direction. The width of the lifting plate is 1-1.5 times the diameter of the pipe. The inclined guide rods are inclined towards the lifting plate in a downward direction. A lifting cylinder electrically connected to the control system is provided on the material rack. The lifting plate is disposed on the piston rod of the lifting cylinder.

[0008] By adopting the above technical solution, the control system starts the lifting cylinder, the piston rod of the lifting cylinder extends, and the piston rod of the lifting cylinder pushes the lifting plate to rise. The rising lifting plate lifts a pipe. Since the upper surface of the lifting plate is inclined towards the preheating platform, after the pipe moves to the top of the baffle, the pipe will roll from the top of the baffle onto the preheating platform.

[0009] Optionally, the material transfer component includes multiple guide plates disposed on the preheating platform. The multiple guide plates are arranged along the axial direction of the pipe. The top of the guide plates is inclined towards the tapered platform from top to bottom. The highest point of the inclined guide plate is lower than the top of the baffle frame. Multiple grooves are formed on the guide plates along their inclined direction. Multiple material transfer cylinders electrically connected to the control system are disposed on the guide plates. Each material transfer cylinder corresponds to one of the grooves. A material transfer plate is disposed on the piston rod of the material transfer cylinder. The material transfer plate is used to push the pipe in the groove.

[0010] By adopting the above technical solution, the pipe rolling down from the top of the baffle will fall into the groove on the guide plate. The control system starts the transfer cylinder, the piston rod of the transfer cylinder extends, and the piston rod of the transfer cylinder lifts the pipe in the groove through the transfer plate. The pipe will slide along the inclined direction of the top of the guide plate to the next groove, and so on, until the transfer process of the pipe is completed.

[0011] Optionally, the ring-shifting component includes a ring-shifting slide rail and a ring-shifting cylinder disposed on the preheating platform. The ring-shifting cylinder is electrically connected to the control system. A mounting plate is slidably disposed on the ring-shifting slide rail. The high-frequency heating coil is disposed on the mounting plate, and the mounting plate is disposed on the piston rod of the ring-shifting cylinder.

[0012] By adopting the above technical solution, after the pipe falls into a groove at the lowest point of the guide plate, the control system starts the transfer cylinder. The piston rod of the transfer cylinder extends and drives the high-frequency heating coil on the mounting plate to gradually wrap around the end of the pipe. The high-frequency heating coil rapidly heats the end of the pipe. Then, the piston rod of the transfer cylinder retracts and drives the high-frequency heating coil on the mounting plate to reset. The heated pipe will then move to the next station.

[0013] Optionally, the clamping assembly includes guide plates disposed at both ends of the tapered frame along its length. The top surface of the guide plate is parallel to the top surface of the guide plate. The highest point of the guide plate is close to and lower than the lowest point of the guide plate. The tube rolls along the inclined surfaces at the top of the two guide plates. Two C-shaped clamping blocks are rotatably disposed at the middle position of the guide plates of the tapered frame. The two clamping blocks are used to clamp the tube on the guide plates. The tapered frame is provided with a splitting and engaging component that drives the two clamping blocks to rotate respectively.

[0014] By adopting the above technical solution, the heated pipe rolls along the inclined direction of the guide plate until it hits the clamping block near the lower inclined end of the guide plate. Then, the separating and joining components drive the C-shaped concave sides of the two clamping blocks to gradually approach each other until the pipe is clamped by the two clamping blocks, thus completing the initial fixation of the pipe. After the pipe is tapered, the two clamping blocks separate from each other, and the clamping block located on the lower inclined end of the guide plate moves to the lower surface of the inclined guide plate. The pipe rolls away from the guide plate along the inclined direction of the guide plate.

[0015] Optionally, the splitting and engaging component includes two splitting and engaging cylinders disposed on the tapered frame and electrically connected to the control system. The splitting and engaging cylinders correspond one-to-one with the clamping blocks. A gear is coaxially disposed at the rotation center of the clamping block, and a rack is disposed on the piston rod of the splitting and engaging cylinder that meshes with the gear.

[0016] By adopting the above technical solution, the control system starts the splitting and closing cylinders. The piston rod of the splitting and closing cylinders drives the rack to slide, and the sliding rack drives the gear to rotate. Through the step-by-step operation of the two splitting and closing cylinders, the pipes on the inclined guide plate are fixed and released.

[0017] Optionally, the retracting component includes a retracting cylinder disposed on the tapering platform, the retracting cylinder being electrically connected to the control system, the tapering frame being disposed on the piston rod of the retracting cylinder, and a retracting slide rail being disposed on the tapering platform, the tapering frame being slidably engaged with the retracting slide rail.

[0018] By adopting the above technical solution, the control system starts the push-shrink cylinder, the piston rod of the push-shrink cylinder extends, and the piston rod of the push-shrink cylinder pushes the tapering frame to slide along the length direction of the push-shrink slide rail, so that the heated end of the pipe is close to the tapering mold, thereby tapering the end of the pipe.

[0019] Optionally, the tapering frame is provided with a tube baffle plate, which is located between the push-shrink cylinder and the guide plate, and the tube baffle plate is used to abut against the end of the tube facing away from the tapering mold.

[0020] By adopting the above technical solution, as the pipe approaches the tapering mold, the end of the pipe facing away from the tapering mold abuts against the baffle plate, thereby synchronizing the pipe at one end, reducing the relative sliding between the pipe and the clamping block, and reducing the possibility of surface damage to the pipe.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Workers use hoisting equipment to stack pipes on a material rack. The loading unit transports the pipes from the rack to the preheating platform. The coil shifting unit drives a high-frequency heating coil to be fitted onto the end of the pipe for rapid heating. Then, the shifting unit transports the heated pipe to a tapering platform. After the clamping assembly fixes the heated pipe, the pushing unit pushes the heated end of the pipe close to the tapering mold. The tapering mold tapes the end of the pipe. Finally, the tapered pipe is transported away by the transfer equipment. In this process, there is no need for workers to operate hydraulic presses or semi-automatic spinning equipment, which greatly improves the processing efficiency of the pipe. 2. After the pipe falls into a groove at the lowest point of the inclined guide plate, the control system activates the transfer cylinder. The piston rod of the transfer cylinder extends and drives the high-frequency heating coil on the mounting plate to gradually wrap around the end of the pipe. The high-frequency heating coil rapidly heats the end of the pipe. Then, the piston rod of the transfer cylinder retracts and drives the high-frequency heating coil on the mounting plate to reset. The heated pipe will then move to the next station. 3. The control system starts the splitting and closing cylinders. The piston rod of the splitting and closing cylinders drives the rack to slide, and the sliding rack drives the gear to rotate. Through the step-by-step operation of the two splitting and closing cylinders, the pipes on the inclined guide plate are fixed and released. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0027] This application discloses a fully automated tip reduction system.

[0028] Reference Figure 1 A fully automated tapering system includes a material rack 1, a preheating platform 2 and a tapering platform 3 arranged in sequence. A tapering mold 4 is arranged at one end of the tapering platform 3. The tapering mold 4 has a mold opening 15 for inserting the end of the pipe 5. Several pipes 5 are stacked on the material rack 1. A baffle frame 13 is welded on both sides of the material rack 1 along the axial direction of the pipe 5.

[0029] Reference Figure 1 The material rack 1 is equipped with a feeding component 6, which is used to sequentially transport the pipes 5 on the material rack 1 to the preheating platform 2.

[0030] Reference Figure 1 and Figure 2 The feeding component 6 includes multiple inclined guide rods 61 welded between two baffle frames 13. The multiple inclined guide rods 61 are arranged along the axial direction of the pipe 5. A lifting plate 62 is vertically slidably arranged on the baffle frame 13 on the material rack 1 and on the side close to the preheating platform 2. The vertical sidewall of the lifting plate 62 is close to the baffle frame 13, and the upper surface of the lifting plate 62 is inclined towards the preheating platform 2 in a downward direction.

[0031] Reference Figure 1 and Figure 2 The width of the lifting plate 62 is 1-1.5 times the diameter of the pipe 5. The inclined guide rod 61 is inclined towards the lifting plate 62 in a downward direction. The lifting cylinder 63, which is electrically connected to the control system, is bolted to the material rack 1. The lifting plate 62 is bolted to the piston rod of the lifting cylinder 63. The lifting cylinder 63 is located at both ends of the length of the lifting plate 62.

[0032] Workers use hoisting equipment to stack pipes 5 on the material rack 1. The baffles 13 on both sides of the material rack 1 restrict the rolling of the pipes 5. When feeding is required, the control system activates the lifting cylinder 63. The piston rod of the lifting cylinder 63 extends and pushes the lifting plate 62 to rise. The rising lifting plate 62 lifts a pipe 5. After the pipe 5 moves to the top of the baffle 13, the pipe 5 will roll from the top of the baffle 13 to the preheating platform 2. Then, the control system controls the lifting cylinder 63 to drive the lifting plate 62 to descend and reset.

[0033] Reference Figure 1 and Figure 2 A high-frequency heating coil 7, which is electrically connected to the control system, is horizontally slidably arranged on the preheating platform 2. The high-frequency heating coil 7 is used to be sleeved on the end of the pipe 5. A material transfer component 8 is arranged on the preheating platform 2. The material transfer component 8 is used to transport the pipe 5 on the preheating platform 2 to the tapering platform 3.

[0034] Reference Figure 1 and Figure 2 The material transfer component 8 includes multiple guide plates 81 arranged on the top of the preheating platform 2. The multiple guide plates 81 are arranged along the axial direction of the pipe 5. The top of the guide plates 81 is inclined towards the tapered platform 3 in a downward direction. The highest point of the inclination of the guide plates 81 is close to the baffle frame 13 and the highest point of the inclination of the guide plates 81 is lower than the top of the baffle frame 13.

[0035] Reference Figure 1 and Figure 2 Two grooves 82 are formed on the guide plate 81 along its inclined direction. Two transfer cylinders 83 electrically connected to the control system are bolted to the guide plate 81. The transfer cylinders 83 correspond one-to-one with the grooves 82. A transfer plate 84 is bolted to the piston rod of the transfer cylinder 83. The upper surface of the transfer plate 84 is inclined towards the preheating platform 2 in the direction from top to bottom. The transfer plate 84 is used to push the pipe 5 in the groove 82.

[0036] Reference Figure 2 The preheating platform 2 is equipped with a coil shifting component 9, which is used to drive the high-frequency heating coil 7 to move back and forth.

[0037] Reference Figure 2The ring-shifting component 9 includes a ring-shifting slide rail 91 and a ring-shifting cylinder 92 bolted to the preheating platform 2. The ring-shifting cylinder 92 is electrically connected to the control system. A mounting plate 93 is slidably arranged on the ring-shifting slide rail 91. The high-frequency heating coil 7 is bolted to the mounting plate 93, and the mounting plate 93 is bolted to the piston rod of the ring-shifting cylinder 92.

[0038] The pipe 5 moves from the baffle frame 13 to the guide plate 81. The pipe 5 rolls along the inclined direction of the guide plate 81 into the groove 82. Then, the control system starts the transfer cylinder 83. The piston rod of the transfer cylinder 83 extends and pushes the pipe 5 in the groove 82 out of the groove 82 through the transfer plate 84. The pipe 5 rolls along the inclined top of the guide plate 81 into the next groove 82.

[0039] At this time, the control system starts the transfer cylinder 92, the piston rod of the transfer cylinder 92 extends, and the piston rod of the transfer cylinder 92 drives the high-frequency heating coil 7 to be sleeved on the end of the pipe 5 through the mounting plate 93. The high-frequency heating coil 7 heats the end of the pipe 5. Then, the control system starts the transfer cylinder 92 again, and the piston rod of the transfer cylinder 92 drives the high-frequency heating coil 7 on the mounting plate 93 to reset. The control system starts the transfer cylinder 83 corresponding to the pipe 5 after heating. The heated pipe 5 moves along the guide plate 81 to the tapered platform 3.

[0040] Reference Figure 1 and Figure 3 A tapering frame 10 is slidably arranged on the tapering platform 3. The length direction of the tapering frame 10 is parallel to the axial direction of the pipe 5. A clamping assembly 11 is arranged on the tapering frame 10. The clamping assembly 11 is used to fix the pipe 5. The clamping assembly 11 includes guide plates 111 bolted to both ends in the length direction of the tapering frame 10. The top surface of the guide plate 111 is parallel to the top surface of the guide plate 81.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The highest point of the guide plate 111 is close to and lower than the lowest point of the guide plate 81. The tube 5 rolls down along the inclined surface at the top of the two guide plates 111. Two C-shaped clamping blocks 112 are rotatably connected at the middle position of the guide plate 111 of the tapered frame 10. The two clamping blocks 112 are used to clamp the tube 5 on the guide plate 111. The tapered frame 10 is provided with a splitting and joining component 113 that drives the two clamping blocks 112 to rotate respectively.

[0042] Reference Figure 1 , Figure 2 and Figure 3The splitting and engaging component 113 includes two splitting and engaging cylinders 1131 that are bolted to the tapered frame 10 and electrically connected to the control system. The splitting and engaging cylinders 1131 correspond one-to-one with the clamping blocks 112. A gear 1132 is coaxially bolted to the rotation center of the clamping blocks 112. A rack 1133 that meshes with the gear 1132 is bolted to the piston rod of the splitting and engaging cylinder 1131.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A pusher 12 is arranged on the tapering platform 3. The pusher 12 is used to drive the tapering frame 10 to approach or move away from the tapering mold 4. The pusher 12 includes a pusher cylinder 121 bolted to the tapering platform 3. The pusher cylinder 121 is electrically connected to the control system. The tapering frame 10 is bolted to the piston rod of the pusher cylinder 121.

[0044] Reference Figure 1 and Figure 3 A push-retract slide rail 122 is bolted to the tapered platform 3. The tapered frame 10 slides in conjunction with the push-retract slide rail 122. A baffle plate 14 is bolted to the tapered frame 10. The baffle plate 14 is located between the push-retract cylinder 121 and the guide plate 111. The baffle plate 14 is used to abut against the end of the pipe 5 facing away from the tapered mold 4.

[0045] After heating, the pipe 5 will roll from the guide plate 81 onto the guide plate 111 until the pipe 5 hits the clamping block 112 on the lower inclined side of the guide plate 111. At this time, the control system activates two split-and-close cylinders 1131. The piston rod of the split-and-close cylinder 1131 drives the rack 1133 to slide. The sliding rack 1133 drives the gear 1132 to rotate. Through the step-by-step operation of the two split-and-close cylinders 1131, the concave sides of the two clamping blocks 112 are brought closer to each other until the pipe 5 is clamped.

[0046] The control system starts the push-shrink cylinder 121, the piston rod of the push-shrink cylinder 121 extends, and the piston rod of the push-shrink cylinder 121 pushes the tapering frame 10 to slide along the length direction of the push-shrink slide rail 122. The end of the pipe 5 facing away from the tapering mold 4 abuts against the baffle plate 14, so that the heated end of the pipe 5 is inserted into the mold opening 15 of the tapering mold 4. The tapering mold 4 performs tapering treatment on the heated end of the pipe 5.

[0047] Finally, the control system controls the two opening and closing cylinders 1131. The piston rods of the opening and closing cylinders 1131 retract. At this time, the clamping block 112 located on the lower side of the inclined guide plate 111 will rotate to the lower surface of the inclined upper surface of the guide plate 111. The pipe 5 will roll away from the guide plate 111 along the inclined direction of the guide plate 111. After that, the control system controls the opening and closing cylinders 1131 to reset the clamping block 112 located on the lower side of the inclined guide plate 111.

[0048] The implementation principle of a fully automated tapering system according to an embodiment of this application is as follows: Workers use hoisting equipment to stack pipes 5 on the material rack 1. The baffles 13 on both sides of the material rack 1 restrict the rolling of the pipes 5. When feeding is required, the control system starts the lifting cylinder 63. The piston rod of the lifting cylinder 63 extends and pushes the lifting plate 62 to rise. The rising lifting plate 62 lifts a pipe 5. After the pipe 5 moves to the top of the baffle 13, the pipe 5 will roll from the top of the baffle 13 to the preheating platform 2. Then, the control system controls the lifting cylinder 63 to drive the lifting plate 62 to descend and reset.

[0049] The pipe 5 moves from the baffle frame 13 to the guide plate 81. The pipe 5 rolls along the inclined direction of the guide plate 81 into the groove 82. Then, the control system starts the transfer cylinder 83. The piston rod of the transfer cylinder 83 extends and pushes the pipe 5 in the groove 82 out of the groove 82 through the transfer plate 84. The pipe 5 rolls along the inclined top of the guide plate 81 into the next groove 82.

[0050] At this time, the control system starts the transfer cylinder 92, the piston rod of the transfer cylinder 92 extends, and the piston rod of the transfer cylinder 92 drives the high-frequency heating coil 7 to be sleeved on the end of the pipe 5 through the mounting plate 93. The high-frequency heating coil 7 heats the end of the pipe 5. Then, the control system starts the transfer cylinder 92 again, and the piston rod of the transfer cylinder 92 drives the high-frequency heating coil 7 on the mounting plate 93 to reset. The control system starts the transfer cylinder 83 corresponding to the pipe 5 after heating. The heated pipe 5 moves along the guide plate 81 to the tapered platform 3.

[0051] After heating, the pipe 5 will roll from the guide plate 81 onto the guide plate 111 until the pipe 5 hits the clamping block 112 on the lower inclined side of the guide plate 111. At this time, the control system activates two split-and-close cylinders 1131. The piston rod of the split-and-close cylinder 1131 drives the rack 1133 to slide. The sliding rack 1133 drives the gear 1132 to rotate. Through the step-by-step operation of the two split-and-close cylinders 1131, the concave sides of the two clamping blocks 112 are brought closer to each other until the pipe 5 is clamped.

[0052] The control system starts the push-shrink cylinder 121, the piston rod of the push-shrink cylinder 121 extends, and the piston rod of the push-shrink cylinder 121 pushes the tapering frame 10 to slide along the length direction of the push-shrink slide rail 122. The end of the pipe 5 facing away from the tapering mold 4 abuts against the baffle plate 14, so that the heated end of the pipe 5 is inserted into the mold opening 15 of the tapering mold 4. The tapering mold 4 performs tapering treatment on the heated end of the pipe 5.

[0053] Finally, the control system controls the two opening and closing cylinders 1131. The piston rods of the opening and closing cylinders 1131 retract. At this time, the clamping block 112 located on the lower side of the inclined guide plate 111 will rotate to the lower surface of the inclined upper surface of the guide plate 111. The pipe 5 will roll away from the guide plate 111 along the inclined direction of the guide plate 111. After that, the control system controls the opening and closing cylinders 1131 to reset the clamping block 112 located on the lower side of the inclined guide plate 111.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
