Description

Technical Field

[0001] This invention relates to the field of hydrogen pipeline processing equipment technology, and in particular to an injection molding connection device for ultra-high pressure anti-permeability lining of hydrogen pipelines. Background Technology

[0002] With the increasing importance of hydrogen as a clean energy source, hydrogen pipelines play a crucial role in hydrogen energy infrastructure. Hydrogen pipelines are an indispensable part of hydrogen energy utilization and the supply chain, and their design, construction, and maintenance require a high level of expertise and technical support. Hydrogen transmission pipelines typically use composite material pipes. Due to the extremely small atomic radius of hydrogen, hydrogen permeation problems exist when using plastic-lined pipes such as PE to transport hydrogen. Therefore, a metal anti-permeability layer needs to be added to the pipe wall or an ultra-high pressure injection-molded lining structure needs to be used to ensure sealing performance. In the pipe connection process, the pipe ends need to be injection-molded to form a continuous and dense inner lining layer at the pipe connection to achieve anti-permeability requirements.

[0003] Hydrogen pipelines typically have large diameters and thin walls. During injection molding, the pipelines need to be clamped. Existing clamping devices mostly use fixed claw structures, which result in uneven clamping force distribution, easily leading to pipeline deformation or insecure clamping. Furthermore, the pipelines are prone to displacement under the high pressure of injection molding, affecting the injection quality. At the same time, the pipeline end and the mold gate need to maintain strict coaxiality. Existing equipment usually relies on manual adjustment for alignment, which is inaccurate and inefficient.

Two bidirectional telescopic cylinders 410 are respectively disposed on one side of the two support frames 409, and the two driving ends of the bidirectional telescopic cylinders 410 are respectively fixedly connected to one side of the corresponding opposing sliders 412.

[0024] Reference Figures 1-5 In a preferred embodiment, the adaptive clamping and positioning module 4 further includes: Multiple electric telescopic cylinders 418 are respectively set on one side of multiple opposing sliders 412. The driving end of each electric telescopic cylinder 418 is fixedly connected to a tooling support frame 405. Two guide rods 9 are fixedly connected to one side of each opposing slider 412. The tooling support frame 405 slides outside the guide rods 9. Multiple pump bodies 10 are respectively set on one side of multiple tooling support frames 405. Both sides of the multiple tooling support frames 405 are connected to two adjusting cylinders 406 through bearings. One end of each of the multiple adjusting cylinders 406 is fixedly connected to a linkage gear 408, and the two linkage gears 408 located on the same side mesh with each other.

[0025] Reference Figures 1-5 In a preferred embodiment, the adaptive clamping and positioning module 4 further includes: Multiple positioning clamping arms 407 are fixedly connected to the outside of multiple adjusting cylinders 406 respectively, and an air pipe 413 is installed on one side of each of the multiple positioning clamping arms 407. Multiple airbags 414 are respectively installed at the air outlet of multiple air pipes 413. Each air inlet of multiple air pipes 413 is provided with a hose 416. Each side of multiple tooling support frames 405 is provided with a drive motor 417. The drive end of the drive motor 417 is fixedly connected to one end of the adjusting cylinder 406 located on the same side. Each side of multiple tooling support frames 405 is provided with a bidirectional inflation pipe 415. One end of the bidirectional inflation pipe 415 is fixedly connected to one end of the hose 416.

[0026] Specifically, the adaptive clamping and positioning module 4 is used to adaptively clamp, center, and prevent displacement of the hydrogen delivery pipe before injection molding. During operation, the display controller 2 sets parameters according to the pipe diameter, length, wall thickness, and end structure. First, the alignment adjustment cylinder 6 drives the horizontal adjustment seat 402 to move along the guide cylinder 401. The spacing adjustment cylinder 7 adjusts the spacing between the two horizontal adjustment seats 402. The electric telescopic cylinder 8 drives the lifting adjustment frame 404 to rise and fall along the guide column 403, so that the support frame 409 and the arc-shaped placement seat 411 are adjusted synchronously, so that the center of the pipe is initially close to the center height of the injection end of the injection molding mechanism 3. After the pipe is placed, the arc-shaped placement seat 411 supports the pipe, and the bidirectional telescopic cylinder 410 drives the opposing slider 412 to slide in opposite directions, so that the tooling support frame 405 is close to the pipe wall. The electric telescopic cylinder 418 drives the tooling support frame 405 to move along the guide rod 9, causing the positioning clamping arm 407 to approach the pipe wall. The drive motor 417 drives the adjusting cylinder 406 on the same side to rotate synchronously in opposite directions through the meshing linkage gear 408, driving the positioning clamping arm 407 to synchronously close or open, ensuring symmetrical clamping center. Subsequently, the pump body 10 supplies air, and the compressed gas enters the air bag 414 through the air blower 12, electronic flow valve 11, bidirectional air inflation pipe 415, hose 416 and medium air pipe 413. The air bag 414 inflates and adheres to the pipe wall. The electronic flow valve 11 adjusts the flow and pressure of the airbags 414 on both sides to make the clamping force evenly distributed along the circumference and axial direction, so as to achieve flexible adaptive clamping and avoid local crushing, ellipticing or deformation of large-diameter thin-walled tubes. After injection molding, the pump body 10 stops supplying air, the electronic flow valve 11 releases pressure or exhausts air in reverse, the airbag 414 contracts, the drive motor 417 rotates in reverse, the positioning clamping arm 407 opens synchronously, the bidirectional telescopic cylinder 410, the electric telescopic cylinder 418 and the horizontal and lifting adjustment mechanism are reset, and demolding and quick shape change are completed. In specific application scenarios, the adaptive clamping and positioning module 4 utilizes an arc-shaped placement seat 411 for support, a bidirectional telescopic cylinder 410 and an opposing slider 412 for clamping, an electric telescopic cylinder 418 and a guide rod 9 for radial feeding, and an airbag 414 for flexible force application. This ensures that the clamping force is evenly distributed along the circumference and axial direction of the pipe, solving the problems of easy deformation and insecure clamping of large-diameter, thin-walled hydrogen pipelines. The airbag 414 adaptively conforms to the pipe wall, and the electronic flow valve 11 adjusts the pressure on both sides to compensate for pipe diameter tolerances and ovality. To avoid localized indentation, the linkage gear 408 causes the positioning clamping arm 407 on the same side to swing synchronously in opposite directions, ensuring symmetrical and stable clamping center. The multi-degree-of-freedom adjustment structure adapts to different pipe diameters, lengths, and wall thicknesses, enabling rapid shape change. During ultra-high pressure injection molding, multi-point flexible clamping resists axial thrust and radial expansion, preventing pipe displacement, swaying, and deformation, ensuring continuous and dense inner lining, and improving sealing and anti-seepage reliability. After injection molding, the airbag 414 depressurizes, and the positioning clamping arm 407 opens synchronously, facilitating demolding and continuous production.

[0027] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the docking positioning module 5 further includes: Multiple electric telescopic rods 502 are respectively installed on multiple sides of the cross support rod 501, and the driving ends of the multiple electric telescopic rods 502 are fixedly connected to the movable frame 503.

[0028] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the docking positioning module 5 further includes: Multiple displacement sensors 504 are respectively disposed on one side of multiple moving frames 503. Each side of multiple moving frames 503 has a smooth hole, and an adaptive smooth rod 505 is slidably connected inside each of the multiple smooth holes.

[0029] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the docking positioning module 5 further includes: Multiple ball bearings 506 are movably connected to one end of multiple adaptive slide rods 505. The adaptive slide rods 505 and the moving frame 503 are fixedly connected to the same telescopic spring 507 on the opposite side of the same spring. The telescopic spring 507 is located outside the adaptive slide rods 505.

[0030] Specifically, the docking positioning module 5 is used to detect the positional deviation between the pipe end and the injection end of the injection mechanism 3 and the gate of the injection mold 13, and automatically complete the coaxial alignment. During operation, the display controller 2 controls multiple electric telescopic rods 502 to extend from multiple directions of the cross support rod 501, driving the moving frame 503 closer to the pipe end. The ball bearing 506 first contacts the outer wall of the pipe to reduce friction and avoid scratches. The telescopic spring 507 causes the adaptive slide rod 505 to float along the smooth hole. The adaptive slide rod 505 retracts or extends according to the actual contour of the pipe end. The displacement sensor 504 detects the displacement of the adaptive slide rod 505 relative to the moving frame 503 in real time and transmits the multi-directional displacement signal to the display controller 2. The display controller 2 calculates the coaxial deviation of the pipe end relative to the gate of the injection mold 13 based on the multi-directional displacement signal, and controls the alignment adjustment cylinder 6, the spacing adjustment cylinder 7 and the electric telescopic cylinder 8 to perform fine adjustments in the span and height directions of the adaptive clamping positioning module 4. During the adjustment process, the docking positioning module 5 continuously detects and provides feedback until the axis of the pipe end coincides with the axis of the injection end of the injection mechanism 3 and the gate axis of the injection mold 13. After the alignment is completed, the injection mechanism 3 performs ultra-high pressure anti-permeability lining injection through the injection mold 13. After the injection is completed, the electric telescopic rod 502 drives the moving frame 503 to retract, the ball 506 disengages from the contact surface, and the adaptive slide rod 505 resets under the action of the telescopic spring 507, waiting for the docking positioning of the next pipe. In specific application scenarios, the docking positioning module 5, through the electric telescopic rod 502 extending from multiple sides of the cross support rod 501, the displacement sensor 504 detecting, and the telescopic spring 507 and the adaptive slide rod 505 floating and cooperating, can obtain the coaxial deviation between the pipe end and the injection mold 13 gate in real time. The display controller 2 automatically adjusts the alignment adjustment cylinder 6, the spacing adjustment cylinder 7 and the electric telescopic cylinder 8 in the adaptive clamping positioning module 4 to make fine adjustments in the horizontal, span and height directions, so as to realize the automatic coaxial alignment between the pipe end and the injection mold 13 gate. This process does not rely on repeated manual adjustment, significantly reducing manual alignment error and improving alignment accuracy and efficiency.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, it further includes: Multiple air-blowing pipes 12 are respectively set at the air-blowing ends of multiple pump bodies 10. One end of the air-blowing pipe 12 is fixedly connected to the inside of the bidirectional air-filling pipe 415. The same spacing adjustment cylinder 7 is set on the opposite side of the two horizontal adjustment seats 402. An alignment adjustment cylinder 6 is set on one side of the injection molding connection platform 1. The drive end of the alignment adjustment cylinder 6 is fixedly connected to one side of one of the horizontal adjustment seats 402.

[0032] Reference Figure 5 In a preferred embodiment, it further includes: Multiple electronic flow valves 11 are respectively installed on the outside of multiple air blasting pipes 12.

[0033] Reference Figure 6 In a preferred embodiment, it further includes: Injection mold 13 is located at the injection port of injection mechanism 3.

[0034] Working principle: When the pipeline lining is injected, the adaptive clamping and positioning module 4 works first. The display controller 2 sets parameters according to the diameter, length, wall thickness and end structure of the hydrogen pipeline to be processed. The alignment and adjustment cylinder 6 drives the horizontal adjustment seat 402 to move along the guide cylinder 401. The spacing adjustment cylinder 7 adjusts the spacing between the two horizontal adjustment seats 402. The electric telescopic cylinder 8 drives the lifting adjustment frame 404 to rise and fall along the guide column 403, which drives the support frame 409 and the arc-shaped placement seat 411 to rise and fall synchronously. After the pipeline is placed, the arc-shaped placement seat 411 supports the pipeline. The bidirectional telescopic cylinder 410 drives the opposing slider 412 to slide in opposite directions, so that the tooling support frame 405 is close to the outer wall of the pipeline. The electric telescopic cylinder 418 drives the tooling support frame 405 to move along the guide rod 9, so that the positioning clamping arm 407 is close to the outer wall of the pipeline. The drive motor 417 drives the same-side adjusting cylinder 406 to rotate synchronously in opposite directions through the meshing linkage gear 408, so that the positioning clamping arm 407 can clamp synchronously. The pump body 10 supplies air. The compressed gas enters the air bag 414 through the air pipe 12, electronic flow valve 11, bidirectional air inflation pipe 415, hose 416 and medium air pipe 413. The air bag 414 inflates and fits against the outer wall of the pipeline. The electronic flow valve 11 adjusts the flow and pressure of each air bag 414. Then the docking positioning module 5 works and the display controller is activated. 2. Multiple electric telescopic rods 502 are controlled to extend from the cross support rod 501 in multiple directions, driving the moving frame 503 to approach the end of the pipe. The ball bearing 506 contacts the outer wall of the pipe. The telescopic spring 507 causes the adaptive slide rod 505 to float along the smooth hole. The adaptive slide rod 505 retracts or extends according to the contour of the pipe end. The displacement sensor 504 detects the displacement of the adaptive slide rod 505 relative to the moving frame 503 in real time and transmits it to the display controller 2. The display controller 2 calculates the coaxial deviation of the pipe end relative to the gate of the injection mold 13 and controls the alignment adjustment cylinder 6, the spacing adjustment cylinder 7 and the electric telescopic cylinder 8 to perform fine adjustments to the adaptive clamping and positioning module 4 in the horizontal, span and height directions until the axis of the pipe end coincides with the axis of the injection end of the injection mechanism 3 and the axis of the gate of the injection mold 13. After alignment, the injection molding mechanism 3 performs ultra-high pressure anti-permeability lining injection through the injection mold 13. After injection, the electric telescopic rod 502 drives the moving frame 503 to retract, the ball bearing 506 disengages from the contact surface, the adaptive slide rod 505 resets under the action of the telescopic spring 507, the pump body 10 stops supplying air, the electronic flow valve 11 releases pressure or exhausts air in reverse, the airbag 414 contracts, the drive motor 417 rotates in reverse, the positioning clamping arm 407 opens synchronously, and the bidirectional telescopic cylinder 410, the electric telescopic cylinder 418, and the horizontal and vertical adjustment mechanisms reset.
