Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering manufacturing industry, in particular to a sizing and forming device and equipment for a flexible oil delivery hose. Background Art

[0002] In the prior art, the tensile layer of flexible, non-bonded hoses (hereinafter referred to as hoses) is sized using a steel support frame connected to a sizing sleeve and a twisting machine. Because the steel support frame is rigid, it lacks sufficient space for the sizing sleeve to move. This results in friction between the flat steel and the sizing sleeve during the production process. This prolonged friction wears the flat steel, potentially causing scratches on the surface of the finished tensile layer, negatively impacting its overall functionality. Furthermore, the rigid tensile force exerted on the sizing sleeve during rotation compresses the flat steel within, potentially causing misalignment and stacking of the flat steel. This results in an uneven appearance of the finished tensile layer and increases the likelihood of lateral buckling. Furthermore, the steel structure connection prevents stress relief during the production of the tensile layer, disrupting the hose design and increasing design deviations, which in turn impacts the hose's overall performance.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0026] Reference Figure 1-Figure 5 As shown, the utility model discloses a sizing and forming device for a flexible oil delivery hose, comprising:

[0027] A slewing assembly 1 includes a capstan 11, wherein at least three first fixing buckles 12 are provided on a surface of the capstan 11; the first fixing buckles 12 are evenly distributed along the circumference of the capstan 11;

[0028] The sizing component 2 includes a sizing sleeve 21 and a flexible connecting belt 22. At least three second fixing buckles 23 are equidistantly arranged on the outer edge of the sizing sleeve 21. One end of the flexible connecting belt 22 is detachably connected to the first fixing buckle 12, and one end of the flexible connecting belt 22 is detachably connected to the second fixing buckle 23. Multiple flexible connecting belts 22 are straightened to drive the sizing sleeve 21 to be coaxially arranged with the winch 11.

[0029] The function of the rotary assembly 1 in the present invention is to provide power for the stranding of the steel strips. Specifically, during the actual stranding process, the rotation of the capstan 11 drives the synchronous rotation of multiple circumferentially arranged steel strips, ultimately stranding the strips together. The primary function of the sizing assembly 2 is to ensure the dimensions of the stranded steel strips. Specifically, the sizing sleeve 21, with its specific size and shape, ensures that the outer or inner diameter of the extruded pipe meets the specified dimensional tolerance range. This facilitates the production of consistent and high-precision pipes and reduces the impact of human factors on pipe dimensions. In the present invention, the sizing sleeve 21 is connected to the capstan 11 via multiple circumferentially arranged flexible connecting straps 22. The ends of the connecting straps are connected to the first fixing buckle 12 on the capstan 11 and the second fixing buckle 23 on the sizing sleeve 21, respectively. To ensure that the sizing sleeve 21 is coaxial with the capstan 11 during use, the multiple flexible connecting straps 22 must be evenly spaced along the circumference of the sizing sleeve 21 and capstan 11.

[0030] The flexible connecting band 22 employed in this utility model can stably tighten the flat steel strips under specified production parameters. During the rotational winding process, it provides the steel strips with sufficient space for movement, reducing friction and squeezing between the strips, making them less susceptible to misalignment. It also eliminates stress between the strips after twisting, ensuring the stability of the formed pipe. Furthermore, the elasticity and deformability of the flexible connecting band 22 provide the sizing sleeve 21 with sufficient space for movement, allowing it to achieve a certain degree of self-adjustment.

[0031] Furthermore, the lengths of the flexible connecting belts 22 are all equal.

[0032] Specifically, in order to ensure that the sizing sleeve 21 is coaxially arranged with the capstan 11 during use, it is also necessary to ensure that the lengths of each flexible connecting belt 22 are equal.

[0033] Furthermore, a buckle 24 is provided at one end of the flexible connecting belt 22 close to the winch 11 , and the end of the flexible connecting belt 22 passes through the buckle 24 to form a telescopic ring 25 , and a first shackle 26 is sleeved on the telescopic ring 25 , and the first shackle 26 cooperates with the first fixing buckle 12 .

[0034] Specifically, the length of the flexible connecting belt 22 determines the distance between the sizing sleeve 21 and the capstan 11. Different articulation distances correspond to twisting of pipes of different diameters. The flexible connecting belt 22 of the present invention is fixed at one end with a buckle 24, which allows for expansion and contraction of the flexible connecting belt 22, making it easy to adjust its length. This adaptability allows for various pipe structures and winding angles, improving the versatility and compatibility of the equipment.

[0035] Furthermore, a second shackle 27 is provided at one end of the flexible connecting belt 22 close to the sizing sleeve 21 , and the second shackle 27 cooperates with the second fixing buckle 23 .

[0036] Specifically, the two ends of the flexible connecting belt 22 in the present invention are respectively provided with a first shackle 26 and a second shackle 27, which facilitates the installation, disassembly and replacement of the flexible connecting belt 22. Compared with the adjustment of the rigid connection, it reduces the installation difficulty and reduces the equipment cost.

[0037] Furthermore, as a preferred embodiment of the present invention, the material of the flexible connecting belt 22 is aramid. Aramid has strong toughness and good elasticity, which allows the sizing sleeve 21 to have a certain amount of room for movement without making it too loose. Example 2

[0038] A sizing and forming device for a flexible oil hose includes the sizing and forming device for a flexible oil hose described in Example 1, characterized in that: the rotary assembly 1 also includes a support sleeve 3 and a guide sleeve 4, the support sleeve 3 and the guide sleeve 4 are both coaxially arranged with the winch 11, one end of the support sleeve 3 is connected to the winch 11, and the guide sleeve 4 is passed through the other end of the support sleeve 3.

[0039] Specifically, during the actual twisting process, the twisted pipe runs through the entire capstan 11, and the pipe needs to be constrained by the guide sleeve 4 to ensure that the axis of the pipe is consistent with the capstan 11. The support sleeve 3 is directly connected to the capstan 11 to support the subsequent installation of the guide sleeve 4.

[0040] Furthermore, the guide sleeve 4 slides axially along the inner wall of the support sleeve 3 .

[0041] Specifically, the guide sleeve 4 can slide in the support sleeve 3 to adjust the distance between the guide sleeve 4 and the sizing sleeve 21. A top screw 7 is provided on the side wall of the support sleeve 3. The top screw 7 passes through the side wall of the support sleeve 3 and abuts against the guide sleeve 4. After adjusting the position of the guide sleeve 4, the top screw 7 is tightened to fix the guide sleeve 4.

[0042] Furthermore, a guide disc 5 is provided at one end of the guide sleeve 4 away from the support sleeve 3, and the outer edge of the guide disc 5 is tapered. In the actual stranding process, it is convenient for the steel strip to cut into the sizing sleeve 21 at a smooth angle during the stranding process.

[0043] Furthermore, a plurality of partition columns 6 are circumferentially provided on the surface of the guide sleeve 4 away from the support sleeve 3 .

[0044] Specifically, a steel strip is passed between any two adjacent separation columns 6 to separate the multiple steel strips, thereby preventing the steel strips from being entangled with each other before entering the sizing sleeve 21, causing problems such as extrusion and dislocation, and ensuring the twisting and forming effect.

[0045] In summary, this utility model introduces a sizing and forming device and apparatus for a flexible oil hose. The flexible connecting band 22 is used to stably tighten a flat steel strip under specified production parameters. During the rotational winding process, the steel strip is given a certain amount of room to move, reducing scraping and squeezing between the steel strips, making them less likely to misalign. The flexible connecting band 22 also eliminates stress between the steel strips after twisting, ensuring the stability of the formed pipe. Furthermore, the elastic deformability of the flexible connecting band 22 provides a certain amount of room for movement for the sizing sleeve 21, giving it a certain degree of automatic adjustment capability. Furthermore, the length of the flexible connecting band 22 can be arbitrarily changed, and by varying the length of the flexible connecting band 22, a variety of pipe body structures and winding angles can be achieved.

[0046] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
