[0002] In the manufacturing of umbilical cable, a ring-shaped plying die is needed to gather each branch line, however, the currently used plying die has only a bundling function, which can only ensure that the relative position of each branch line meets the processing requirements when passing through the plying die, and does not have a shaping function. Once each branch line passes through the plying die, there will be a large lateral slip in the relative position, which will affect the manufacturing tolerance. Therefore, it is necessary to improve the currently used plying die to achieve a shaping function. SUMMARY

[0003] The present application aims at the problem that the existing umbilical cable cabling and plying die device cannot be shaped, and provides an umbilical cable cabling and plying die device, which can effectively realize the shaping function after the umbilical cable is bundled.

[0005] Further, the gap includes an axial gap and a radial gap, the axial gap is greater than 0 and less than 10 mm, and the radial gap is greater than 0 and less than 15% of the radius of the umbilical cable.

[0006] Further, the bundling ring is composed of two symmetrical half-circle grooves, one end of the half-circle groove is a male joint for connection, which can be connected to the female joint of the adjacent shaping ring.

[0007] Further, the shaping ring is composed of two symmetrical half-circle grooves, one end of the half-circle groove is a male joint for connection, which can be connected to the female joint of the adjacent shaping ring; the other end of the half-circle groove is a female joint for connection, which can be connected to the male joint of the adjacent shaping ring, or the male joint of the bundling ring.

[0008] Further, a plurality of through holes are provided on the sidewall of the shaping ring along the radial direction, which are used for visually checking whether the state of the umbilical cable in the shaping ring is normal.

[0009] Further, the shaping ring is provided with a plurality of grooves in the circumferential direction, the shaping ring at the end away from the bundling ring, all the grooves are used for placing the binding rope for binding two half circular grooves; the shaping ring at the middle position, the groove close to the male joint is used for connecting the female knot head of the adjacent shaping ring, and the other grooves are used for placing the binding rope for binding two half circular grooves.

[0010] Further, a plurality of matched pin holes and pins are arranged on the half circular groove abutting surface of the shaping ring, which are used for guiding during assembly of the half circular groove and positioning after assembly.

[0011] Compared with the prior art, the umbilical cable cabling and plying die device has the following advantages:

[0012] 1) The umbilical cable cabling and plying die device comprises a bundling ring and a plurality of shaping rings, each branch of the umbilical cable is passed through the bundling ring and then the shaping rings in sequence, so that the relative positions of the branches can be maintained.

[0013] 2) The number and length of the shaping rings are determined according to the length of the designed pitch of the umbilical cable.

[0014] 3) The bundling ring and the shaping ring can be split into two half circular grooves, so as to facilitate assembly and disassembly.

[0015] 4) The connecting part between the bundling ring and the shaping ring and the connecting part between the shaping rings have a certain gap, so that the umbilical cable cabling and plying die device can be freely bent in the axial direction by a certain angle, so as to prevent local bending stress concentration of the umbilical cable when passing through the plying die. The umbilical cable cabling and plying die device can effectively realize the function of shaping the umbilical cable after bundling by increasing the shaping ring group which can be freely bent in the axial direction and the length of which can be adjusted.

[0016] In summary, compared with the prior art, the umbilical cable cabling and plying die device provided by the present application can effectively solve the lateral deformation phenomenon of the umbilical cable during cabling, so as to improve the cabling processing precision of the umbilical cable.
