Description

Technical Field

[0001] This utility model belongs to the field of MPP power pipe production technology, specifically relating to an MPP power pipe flaring device. Background Technology

[0002] The flaring process is a crucial step in the manufacturing of MPP power conduits. Flared pipe ends can be tightly fitted with other pipe sections or fittings via a socket joint, forming a sealed connection that provides excellent waterproof and dustproof performance at the pipe joint. The flaring device efficiently and uniformly expands the pipe ends, and its structural design ensures the quality and consistency of the flaring process.

[0003] Chinese patent document CN221793789U discloses an end flaring device for cable protection pipe production. The device uses a first cylinder to push a heating head to be inserted into the cable protection pipe to preheat and soften it. Then, the cable protection pipe is moved to the flaring mechanism. Once the flaring component of the flaring mechanism is inserted into the cable protection pipe, an electric push rod pushes a tensioning block to squeeze between the flaring blocks, opening the flaring blocks. Finally, a drive motor drives the flaring blocks to rotate at the end of the cable protection pipe through a rotating sleeve, thus completing the flaring of the cable protection pipe end.

[0004] However, in the existing technology, the flaring block is prone to mechanical interference with the heated and softened inner wall of the pipe during rotation, causing scratches on the inner wall of the pipe. Moreover, when the pipe is heated and moved to the flaring station, the flaring accuracy is easily reduced due to heat loss or axial displacement. Therefore, a flaring device for producing MPP power pipes is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a device for flaring out MPP power pipes.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An MPP power pipe flaring device includes a loading assembly that provides installation positions for key components of the device. The loading assembly contains an accessory that allows the device to be kept coaxial with the pipe for flaring. One side of the accessory has a flaring component that can be inserted into the end of the pipe and flared to the desired extent.

[0008] The loading assembly includes a first carrier;

[0009] The flaring assembly includes a contact element that prevents mechanical damage to the inner wall of the pipe due to flaring, a rotating element that can install the contact element and drive it to rotate inside the pipe, and a pushing element that allows the device to meet the flaring needs of pipes of various sizes and specifications.

[0010] The rotating component includes a sleeve mounted on one side of the first carrier;

[0011] The contact element includes multiple guide frames fixedly connected to the outer side of the sleeve frame. A guide rod is movably connected to the side of the guide frame away from the sleeve frame. A transmission seat is fixedly connected to the end of the guide rod away from the guide frame. A rotating rod is movably connected between two transmission seats with the same longitudinal position and height. A tapered cylinder is fixedly connected to the outer side of the rotating rod.

[0012] Preferably, the rotating component further includes a bearing fixedly connected to one side of the first carrier, a rotating shaft coaxial with and passing through the bearing is movably installed in the bearing, a sleeve is fixedly connected to the outer side of the rotating shaft, and a motor is fixedly installed on the other side of the first carrier.

[0013] Preferably, the pushing component includes a second electric push rod fixedly installed on the side of the first carrier near the motor. The telescopic end of the second electric push rod is fixedly connected to a transverse block. A limit block is fixedly connected to one side of the transverse block. Multiple ball joints are provided between the transverse block and the limit block. An internal threaded cylinder is provided between the adjacent transmission seat and the ball joint.

[0014] Preferably, the bearing seat is rotatably connected to the rotating shaft, the guide frame is slidably connected to the guide rod, and the transmission seat is rotatably connected to the rotating rod.

[0015] Preferably, the transmission seat is rotatably connected to the internal threaded cylinder, the transverse block and the limiting block are slidably connected to the ball head rod, and the ball head rod and the internal threaded cylinder are connected by threads.

[0016] Preferably, multiple guide frames, guide rods, transmission seats, rotating rods, tapered cylinders, ball-end rods, and internally threaded cylinders are arranged at equal angular intervals around the axis of the rotating shaft.

[0017] Preferably, the inner diameters of the transverse block and the limiting block are the same and both are larger than the diameter of the circumcircle of the longitudinal section of the sleeve frame.

[0018] The beneficial effects of this utility model are as follows: Based on the fact that the accessory can heat and cool the pipeline and that the device and the pipeline can be kept coaxial, the conical cylinder that can rotate on its own axis and around the center line of the pipeline can be set so that the pipeline can be flared when the position of the conical cylinder is adjusted by the pushing component. This avoids the temperature loss and positioning deviation caused by the secondary transfer of the pipe through the in-situ processing mode, and eliminates the risk of mechanical interference of the flaring process on the softened pipe wall.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5 As shown, an MPP power pipe flaring device includes a loading assembly 1 that provides an installation position for key components of the device. The loading assembly 1 is provided with an accessory 2 that allows the device to be kept coaxial with the pipe for flaring. On one side of the accessory 2, a flaring assembly 3 is provided that can be inserted into the end of the pipe and flared to the required extent.

[0031] In this embodiment: the loading assembly 1 includes a first carrier 101, a second carrier 102 is provided on one side of the first carrier 101, a transverse frame 103 is provided on one side of the second carrier 102, a fixed frame 104 is provided on one side of the transverse frame 103, a plurality of first electric push rods 105 are fixedly installed on the outer side of the second carrier 102, which are arranged laterally and whose telescopic ends are fixedly connected to the transverse frame 103, a plurality of crossbars 106 are provided between the first carrier 101, the second carrier 102, the transverse frame 103, and the fixed frame 104, and positioning nuts 107 that are threadedly connected to the crossbars 106 are provided on both sides of the first carrier 101, the second carrier 102, and the fixed frame 104;

[0032] The transverse frame 103 is slidably connected to the crossbar 106, and the first carrier 101, the second carrier 102, the transverse frame 103, and the fixed frame 104 are coaxial;

[0033] The first carrier 101 provides mounting positions for components such as the bearing 301, motor 304, and second electric actuator 310, allowing these components to partially or completely penetrate it. The second carrier 102, which is laterally close to the conical cylinder 309, provides mounting positions for components such as the first electric actuator 105 and air intake frame 203. The transverse frame 103 and the fixed frame 104 provide mounting positions for each connecting rod 201. The first electric actuator 105 drives the transverse frame 103 to move laterally relative to the crossbar 106, thereby changing the distance between the transverse frame 103 and the fixed frame 104. The positioning nut 107 restricts the positional changes of the first carrier 101, the second carrier 102, and the fixed frame 104 relative to the crossbar 106.

[0034] In this embodiment: Annex 2 includes multiple connecting rods 201 that are movably connected to the transverse frame 103 and the fixed frame 104 respectively. A clamping plate 202 is provided between two connecting rods 201 with the same longitudinal position and height. An air intake frame 203 is fixedly installed in the second carrier frame 102. One-way valves 204 are fixedly connected to the front and rear of the air intake frame 203. A ring network 205 is fixedly connected to the inner side of the air intake frame 203.

[0035] The transverse frame 103 and the fixed frame 104 are rotatably connected to the connecting rod 201. The connecting rod 201 is rotatably connected to the clamping plate 202. The air intake frame 203 is a hollow structure. Multiple mesh holes are integrally formed on the ring mesh 205 (not shown in the attached figure).

[0036] The clamping plate 202 is installed around the axis of the first carrier frame 101 and other components via the connecting rod 201, and the position of the clamping plate 202 can change due to the change in the distance between the transverse frame 103 and the fixed frame 104. Multiple clamping plates 202 with synchronously changing positions contact and clamp the pipe to be flared, so that the pipe after contacting each clamping plate 202 can be coaxial with the first carrier frame 101 and other components. The external gaseous cold and hot media are respectively introduced into the annular and hollow air intake frame 203 through two one-way valves 204. The cold and hot media entering the air intake frame 203 can be dispersed and flow to the conical cylinder 309 and other components located at the center of the second carrier frame 102 through the ring network 205.

[0037] In this embodiment: the flaring assembly 3 includes a contact element that can prevent mechanical damage to the inner wall of the pipe due to flaring, a rotating element that can install the contact element and drive it to rotate inside the pipe, and a pushing element that can enable the device to meet the flaring needs of pipes of various sizes and specifications.

[0038] The rotating component includes a sleeve frame 303 disposed on one side of the first carrier 101. The contact component includes multiple guide frames 305 fixedly connected to the outer side of the sleeve frame 303. A guide rod 306 is movably connected to the side of the guide frame 305 away from the sleeve frame 303. A transmission seat 307 is fixedly connected to the end of the guide rod 306 away from the guide frame 305. A rotating rod 308 is movably connected between two transmission seats 307 with the same longitudinal position and height. A tapered cylinder 309 is fixedly connected to the outer side of the rotating rod 308. The rotating component also includes a bearing seat 301 fixedly connected to one side of the first carrier 101. The inner rotating shaft 302 is coaxially mounted and passes through it. The outer side of the rotating shaft 302 is fixedly connected to the sleeve 303. The motor 304 is fixedly mounted on the other side of the first carrier 101. The pushing component includes a second electric push rod 310 fixedly mounted on the side of the first carrier 101 near the motor 304. The telescopic end of the second electric push rod 310 is fixedly connected to a transverse block 311. A limit block 312 is fixedly connected to one side of the transverse block 311. A plurality of ball head rods 313 are provided between the transverse block 311 and the limit block 312. An internal threaded cylinder 314 is provided between the adjacent transmission seat 307 and the ball head rods 313.

[0039] The center line of the first carrier 101 coincides with that of the bearing 301. The bearing 301 is rotatably connected to the rotating shaft 302. The guide frame 305 is slidably connected to the guide rod 306. The transmission seat 307 is rotatably connected to the rotating rod 308. The transmission seat 307 is rotatably connected to the internal threaded cylinder 314. The transverse block 311 and the limiting block 312 are slidably connected to the ball head rod 313. The ball head rod 313 and the internal threaded cylinder 314 are connected by threads. Multiple guide frames 305, guide rods 306, transmission seats 307, rotating rods 308, conical cylinders 309, ball head rods 313, and internal threaded cylinders 314 are all arranged at equal angular intervals around the axis of the rotating shaft 302. The inner diameters of the transverse block 311 and the limiting block 312 are the same and are all larger than the diameter of the circumscribed circle of the longitudinal section of the sleeve frame 303.

[0040] The motor 304, after operation, drives the rotating shaft 302, which is mounted on one side of the first carrier 101 by the bearing seat 301, to rotate. The sleeve 303 provides an installation position for the guide frame 305 and drives it to rotate with the rotating shaft 302. The guide frame 305 and the guide rod 306, which can slide relative to the guide frame 305, limit the transmission seat 307 and make the distance between the transmission seat 307 and the sleeve 303 variable. The rotating rod 308, which can rotate relative to the transmission seat 307, installs the conical cylinder 309 between two transmission seats 307 that are in the same longitudinal position and height but different lateral positions. This allows the distance between the conical cylinder 309 and the sleeve 303 to change due to the position of the transmission seat 307. The conical cylinder 309 contacts the inner wall of the pipe, and the two telescopic ends can penetrate the second pipe of the first carrier 101. The electric actuator 310 is installed on the transverse block 311, so that the transverse block 311 can be positioned so that its center line coincides with the axis of the rotating shaft 302. When the second electric actuator 310 is running, it moves laterally relative to the rotating shaft 302 and the sleeve frame 303. The limit block 312 cooperates with the transverse block 311 to form an annular groove that can limit the ball head at the end of the ball head rod 313, so that the ball head rod 313 can rotate around the axis of the rotating shaft 302 and the degree of inclination can be changed, but it cannot be separated from the transverse block 311 and the limit block 312. The lateral position change of the transverse block 311 is transmitted to the transmission seat 307 connected to the internal threaded cylinder 314 after changing the direction of the transverse position change through the ball head rod 313 and the internal threaded cylinder 314. When the ball head rod 313 rotates relative to the internal threaded cylinder 314 which is threaded to it, the distance between the transmission seat 307 and the ball head at the end of the ball head rod 313 can change.

[0041] Working principle: When the device is installed and the flaring work for the production of MPP power pipes is completed, the two one-way valves 204 are connected to the external cold and hot medium supply equipment respectively. According to the size of the inner diameter of the pipe, each ball head rod 313 is rotated in advance so that the maximum distance between the main body of the conical cylinder 309 and the axis of the rotating shaft 302 is slightly less than the inner diameter of the pipe. Then, the pipe is inserted from the end of the device away from the motor 304.

[0042] When the side wall of the pipe at the end that needs to be flared is against the position of the largest radius at the tail end of the conical cylinder 309, the first electric actuator 105 is made to drive the transverse frame 103 to move towards the fixed frame 104 so that each clamping plate 202 can move towards the pipe until it is pressed against the outer wall of the pipe. When the clamping plate 202 clamps the pipe, the center line of the pipe will coincide with the axis of the rotating shaft 302.

[0043] Then, heat medium can be supplied to the air intake frame 203 surrounding the end of the pipe to heat the pipe to a suitable temperature for widening. Then, the motor 304 and the second electric push rod 310 can be run so that the conical cylinder 309, which can rotate due to the rotating rod 308, can move appropriately away from the rotating shaft 302 while rotating with the rotating shaft 302, until the pipe is widened to the required extent.

[0044] After the flaring is completed, refrigerant can be supplied into the air intake frame 203 at an opportune time to cool and shape the pipe, and the conical cylinder 309 and clamping plate 202 can be reset in sequence to make the flared pipe easy to remove.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
