Description

Technical Field

[0001] The present invention relates to the technical field of pipeline forming, and more particularly to a composite material pipeline forming die. Background Art

[0002] CFRTP pipeline is made of two high-quality raw materials, carbon fiber and PEEK. PEEK (polyetheretherketone) is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. Due to its heat resistance, it is often used in oilfield chemicals. Unidirectional carbon fiber and PEEK tape are laser welded and fully automatic robots weld layer by layer to form a smooth and fully bonded structure. At the same time, the angle of the tape can be modified to optimize the softness, hardness and strength, so that a relatively small amount of material can meet the required performance. CFRTP pipeline has excellent corrosion resistance and has excellent corrosion resistance to hydrogen sulfide, carbon dioxide, acid, alkali and moisture common in oil and gas fields. It is far superior to steel pipes or flexible pipes. CFRTP oil pipeline has good flexibility. It has a minimum bending radius and can be wound on a standard reel for easy handling and construction. Due to its light weight, it can be constructed even on smaller ships. CFRTP pipeline can be laid around the submarine formation and has a high fatigue life, so it is very suitable for dynamic applications.

[0003] During the pipe forming process, in order to increase the service life of the pipe, a wrapping layer is usually added to the outer wall or inner wall of the pipe to prevent the pipe from rupture and increase the service life of the pipe. When an inner support pipe layer is added inside the pipe, a gap is easily generated between the inner support pipe and the pipe body, thereby reducing the overall wrapping of the inner liner pipe on the pipe. In addition, due to the uneven inner wall of the inner liner pipe, the internal pressure of the inner liner pipe is easily uneven, affecting the overall service life of the pipe fittings. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a composite material pipe forming mold, which is raised and lowered by rotating the adjusting cylinder as a whole, so that the connecting arm movable ring on the inner wall of the adjusting cylinder drives the spacing adjustment arm to pull, and during the pulling process of the spacing adjustment arm, the inner liner pipe pressure ring is driven to rise as a whole. During the overall rising process of the inner liner pipe pressure ring, the elastic bracket is fixed as a whole inside the adjusting groove, so that the outer wall of the inner liner pipe pressure ring rises due to the spacing adjustment arm, causing the outer wall of the inner liner pipe pressure ring to expand outward, and the angle of the outer wall of the inner liner pipe pressure ring is adjusted by the number of rotations of the adjusting cylinder. After the expansion is completed, the outer wall of the inner liner pipe pressure ring is always in contact with the inner wall of the inner liner pipe, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a composite material pipe forming mold, comprising an inner liner pipe pressure ring, an adjustment groove is opened at the top of the inner liner pipe pressure ring, a first part connecting arm is arranged at the top of the adjustment groove, a hinge seat is fixedly connected to the bottom of the first part connecting arm, and the hinge seat is fixedly connected to the inside of the adjustment groove, a connecting head is fixedly connected to the top of the first part connecting arm, a hinge matching head is fixedly connected to the top of the hinge matching head, a second part connecting arm is fixedly connected to the top of the articulated matching head, an outer ring is arranged at the top of the inner liner pipe pressure ring, a part connecting ring is fixedly connected to the outer wall of the outer ring, and the top of the second part connecting arm is fixedly connected to the bottom of the part connecting ring, and an adjustment cylinder is arranged inside the outer ring.

[0006] In a preferred embodiment, the number of the adjustment grooves is multiple groups, and the multiple groups of adjustment grooves are arranged in a ring array state with respect to the interior of the adjustment grooves.

[0007] In a preferred embodiment, an elastic bracket is fixedly connected to the inside of the adjustment groove, a reinforced connecting strip is fixedly connected to the top of the elastic bracket, a reinforced supporting rib is fixedly connected to the inside of the adjustment groove, and the reinforced supporting rib is arranged on the top of the elastic bracket.

[0008] In a preferred embodiment, the number of the first part connecting arms is multiple groups, and the multiple groups of first part connecting arms are arranged in a ring array state with respect to the interior of the adjustment groove.

[0009] In a preferred embodiment, the outer wall of the adjusting cylinder is fixedly connected to a first limit strip, the bottom of the adjusting cylinder is fixedly connected to a second limit strip, the interior of the adjusting cylinder is fixedly connected to a connecting arm movable ring, the interior of the connecting arm movable ring is slidably connected to a spacing adjustment arm, and the bottom of the spacing adjustment arm is fixedly connected to the inner wall of the inner liner pipe pressure ring.

[0010] In a preferred embodiment, the number of the spacing adjustment arms is multiple groups, and the multiple groups of spacing adjustment arms are arranged in a ring array state with respect to the interior of the adjustment cylinder.

[0011] In a preferred embodiment, a guide ring is fixedly connected to the top of the adjusting cylinder, a thread groove is formed on the outer wall of the adjusting cylinder, and the thread groove is threadedly connected to the inner wall of the outer ring and the part connecting ring.

[0012] Technical effects and advantages of the present invention:

[0013] The user rotates the outer ring of the outer wall of the adjusting cylinder and the part connecting ring so that the outer ring and the part connecting ring are threadedly connected along the adjusting groove of the outer wall of the adjusting cylinder. The adjusting cylinder rotates as a whole inside the outer ring and the part connecting ring. The adjusting cylinder is lifted and lowered by rotating the adjusting cylinder as a whole, so that the movable ring of the connecting arm on the inner wall of the adjusting cylinder drives the spacing adjustment arm to be pulled. During the pulling process of the spacing adjustment arm, the inner liner tube pressing ring is driven to rise as a whole. During the rising process of the inner liner tube pressing ring as a whole, the elastic bracket is fixed in the adjusting groove as a whole, so that the outer wall of the inner liner tube pressing ring is lifted due to the rising of the spacing adjustment arm, resulting in the outer wall of the inner liner tube pressing ring expanding outwards. The number of rotations of the adjusting cylinder determines the outward expansion angle of the outer wall of the inner liner tube pressing ring as a whole. After the expansion is completed, the outer wall of the inner liner tube pressing ring is always in contact with the inner wall of the inner liner tube.

[0014] The extended end of the liner tube at one end of the guide ring is sealed, and the other end of the liner tube is inflated. When the liner tube pressing ring and the adjusting tube drive the liner tube to be formed in the pipeline, the airflow can penetrate the liner tube through the liner tube pressing ring and the adjusting tube. After the equipment completes the pipeline forming, the air pressure makes the liner tube always fit with the pipeline outside the liner tube after cooling and finalizing, thereby increasing the overall strength and fit of the pipe body.

[0015] When the wire pulls the guide ring, the adjusting cylinder and the inner liner tube pressure ring move synchronously as a whole. At the bend of the pipe, since the adjusting cylinder and the inner liner tube pressure ring are separate independent individuals, when the adjusting cylinder completes the bend, the inner liner tube pressure ring is affected by the connection between the second part connecting arm and the spacing adjusting arm as a whole. The articulated matching head at one end of the second part connecting arm is hinged with the connecting head at the top of the first part connecting arm, so that the inner liner tube pressure ring is adjusted as a whole to the bending angle in the inner liner tube to prevent the equipment from being stuck inside the inner liner tube.

At the bend of the pipe, because the adjusting cylinder 10 and the liner pipe pressing ring 1 are separate and independent entities, when the adjusting cylinder 10 completes the bend, the liner pipe pressing ring 1 is affected by the connection between the second part connecting arm 7 and the spacing adjusting arm 104 as a whole. The articulated matching head 63 at one end of the second part connecting arm 7 is articulated with the connecting head 62 at the top of the first part connecting arm 6, so that the liner pipe pressing ring 1 is adjusted as a whole to the bend angle in the liner pipe to prevent the device from being stuck inside the liner pipe as a whole.

When the inner liner tube is completed and shaped, the extended end of the inner liner tube at one end of the guide ring 11 is sealed, and the other end of the inner liner tube is inflated. When the inner liner tube pressing ring 1 and the adjusting cylinder 10 drive the inner liner tube to be formed in the pipeline as a whole, the airflow can pass through the inner liner tube pressing ring 1 and the adjusting cylinder 10 as a whole to penetrate the inner liner tube, so that after the equipment completes the pipeline forming, the air pressure affects the inner liner tube to always fit with the pipeline outside the inner liner tube after cooling and shaping, thereby increasing the overall strength and fit of the pipe body;

[0027] Refer to the instruction manual Figure 1-7 Furthermore, the outer wall of the adjusting cylinder 10 is fixedly connected with a first limit strip 101, the bottom of the adjusting cylinder 10 is fixedly connected with a second limit strip 102, the interior of the adjusting cylinder 10 is fixedly connected with a connecting arm movable ring 103, the interior of the connecting arm movable ring 103 is slidably connected with a spacing adjustment arm 104, and the bottom of the spacing adjustment arm 104 is fixedly connected to the inner wall of the inner liner pipe pressure ring 1, the number of the spacing adjustment arms 104 is multiple groups, and the multiple groups of spacing adjustment arms 104 are arranged in a ring array state with respect to the interior of the adjusting cylinder 10, the top of the adjusting cylinder 10 is fixedly connected with a guide ring 11, the outer wall of the adjusting cylinder 10 is provided with a threaded groove 12, and the threaded groove 12 is threadedly connected to the outer ring 8 and the inner wall of the part connecting ring 9, the user adjusts the outer ring 8 of the outer wall of the adjusting cylinder 10 by rotating the outer ring 8 The outer ring 8 and the part connecting ring 9 are threadedly connected along the threaded groove 12 on the outer wall of the adjusting tube 10 as a whole, and the adjusting tube 10 is rotated inside the outer ring 8 and the part connecting ring 9 as a whole. The adjusting tube 10 is lifted and lowered by the overall rotation of the adjusting tube 10, so that the connecting arm movable ring 103 on the inner wall of the adjusting tube 10 drives the spacing adjustment arm 104 to pull. During the pulling process of the spacing adjustment arm 104, the inner liner tube pressing ring 1 is driven to rise as a whole. During the overall rising process of the inner liner tube pressing ring 1, the elastic bracket 3 is fixed as a whole inside the adjusting groove 2, so that the outer wall of the inner liner tube pressing ring 1 rises due to the spacing adjustment arm 104, causing the outer wall of the inner liner tube pressing ring 1 to expand outwardly. The angle of the outer wall of the inner liner tube pressing ring 1 is adjusted by the number of rotations of the adjusting tube 10.

[0028] Working principle: When the equipment is in use, one end of the wire is connected to the guide ring 11 on the top of the adjusting tube 10. The inner liner tube pressing ring 1 and the adjusting tube 10 are integrally inside the inner liner tube. In order to ensure that the outer wall of the inner liner tube pressing ring 1 is always in contact with the tube wall of the inner liner tube, the user rotates the outer ring 8 and the part connecting ring 9 on the outer wall of the adjusting tube 10 so that the outer ring 8 and the part connecting ring 9 are threadedly connected along the thread groove 12 on the outer wall of the adjusting tube 10 as a whole. The adjusting tube 10 is rotated as a whole inside the outer ring 8 and the part connecting ring 9. The adjusting tube 10 is lifted and lowered by the overall rotation of the adjusting tube 10. The connecting arm movable ring 103 on the inner wall of the adjusting tube 10 drives the spacing adjusting arm 104 to be pulled. During the pulling process of the spacing adjusting arm 104, the inner The liner pressing ring 1 rises as a whole. During the rising process of the inner liner pressing ring 1, the elastic bracket 3 is fixed as a whole inside the adjusting groove 2, so that the outer wall of the inner liner pressing ring 1 rises due to the spacing adjusting arm 104, causing the outer wall of the inner liner pressing ring 1 to expand outward. The angle of the outer wall of the inner liner pressing ring 1 is adjusted by adjusting the number of rotations of the cylinder 10. After the expansion is completed, the outer wall of the inner liner pressing ring 1 is always in contact with the inner wall of the inner liner. By pulling the wire, the wire drives the inner liner pressing ring 1 and the adjusting cylinder 10 to move forward as a whole. The inner liner pressing ring 1 contacts the inner liner through displacement as a whole, so that the inner liner and the pipeline are in contact. After the inner liner is cooled and finalized, the inner liner is always in contact with the pipeline.

[0029] When the inner liner tube is completed and shaped, the extended end of the inner liner tube at one end of the guide ring 11 is sealed and the other end of the inner liner tube is inflated. When the inner liner tube pressure ring 1 and the adjusting tube 10 drive the inner liner tube to be formed in the pipeline as a whole, the airflow can penetrate the inner liner tube through the inner liner tube pressure ring 1 and the adjusting tube 10 as a whole, so that after the equipment completes the pipeline forming, the air pressure makes the inner liner tube always fit with the pipeline outside the inner liner tube after cooling and shaping, thereby increasing the overall strength and fit of the pipe body. Secondly, a first part connecting arm 6 is provided inside the adjusting groove 2, which is connected to the internal part of the adjusting groove 2 through the hinge seat 61 at the bottom of the first part connecting arm 6, and is fixed to the first part connecting arm 6 through the connecting head 62, so that the hinge at the bottom of the second part connecting arm 7 After the matching head 63 is fixed to the connecting head 62, the first part connecting arm 6 and the second part connecting arm 7 are connected, and one end of the second part connecting arm 7 is fixed to the bottom of the part connecting ring 9, so that when the wire pulls the guide ring 11, the adjusting cylinder 10 and the inner liner tube pressure ring 1 move synchronously as a whole. At the bend of the pipe, because the adjusting cylinder 10 and the inner liner tube pressure ring 1 are separate independent individuals, when the adjusting cylinder 10 completes the bend, the inner liner tube pressure ring 1 is affected by the connection between the second part connecting arm 7 and the spacing adjustment arm 104 as a whole, and the hinged matching head 63 at one end of the second part connecting arm 7 is hinged with the connecting head 62 at the top of the first part connecting arm 6, so that the inner liner tube pressure ring 1 is adjusted as a whole to the bending angle in the inner liner tube to prevent the equipment from being stuck inside the inner liner tube.
