Description

Technical Field

[0001] The utility model belongs to the technical field of tubular stranding machines, and particularly relates to a pre-deformer for a tubular stranding machine. Background Art

[0002] The purpose of pre-deformation is to use certain means to deform the steel wires to a shape that matches the strands before they are twisted into strands, preventing them from becoming loose after being formed into a rope. The pre-deformer primarily consists of three deformation plates and corresponding supporting devices. As the steel wires run along deforming rollers arranged in different combinations, they form a certain wrap angle on the intermediate roller, causing them to undergo a certain amount of plastic deformation. This plastic deformation forms a fixed helical wave shape during stranding, making it less likely for multiple wires of the same shape to become loose after being twisted into a strand. The amplitude and pitch of the steel wire's spiral wave can be achieved by adjusting the wrap angle of the steel wire on the three deformation plates. This adjustment is achieved by adjusting the relative positions of the deformation plates. In other words, the amplitude and pitch of the steel wire's spiral wave can be achieved by adjusting the relative positions of the deformation rollers.

[0003] At present, the three deformation plates of the pre-deformer are mostly fixed by fixing one of the deformation plates to the distribution plate, and the other deformation plate is threadedly sleeved on the core tube, and then fixed by a positioning pin or a bolt and nut structure. When the relative position of the deformation plate needs to be adjusted, the corresponding deformation plate needs to be removed, and then the position is adjusted before being fixed and installed. The adjustment and use are very troublesome and the work efficiency is low. Summary of the Invention

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] like Figures 1 to 14 As shown, this embodiment provides a pre-deformer for a tubular stranding machine, comprising a core-penetrating tube 1 and a wire distribution plate 2 fixedly sleeved at the front end of the core-penetrating tube 1, wherein the core-penetrating tube 1 is used to pass through a rope core (i.e., a steel wire rope), and the wire distribution plate 2 is provided with a plurality of wire-passing holes 21 along its radial direction, and each group of wire-passing holes 21 is arranged in a plurality along the circumference of the wire distribution plate 2 to enable multiple strands of steel wire to pass through separately, and the circular areas surrounded by the plurality of wire-passing holes 21 have different diameters, which can adapt to the passing of steel wires with different requirements. The first cylinder 3, the first sleeve 7, the second cylinder 4, the second sleeve 9 and the third cylinder 5 are sequentially sleeved on the outer circumference of the core tube 1 from the outside to the inside, one end of the first cylinder 3 is fixedly connected to the wire distribution plate 2, and the other end is fixedly provided with a connecting cylinder 3a, and the end of the connecting cylinder 3a away from the wire distribution plate 2 is fixedly provided with a first deformation plate 6, One end of the first sleeve 7 extends into the first cylinder 3, and the other end passes through the connecting tube 3a and extends into the first deformable disk 6, that is, the first deformable disk 6 is fixedly arranged, and the end of the second cylinder 4 away from the distribution disk 2 passes through the first sleeve 7 and the first deformable disk 6 in sequence, and extends into and is fixedly connected to the second deformable disk 8. The first sleeve 7 and the second cylinder 4 are key-connected, and the specific connection method is a guide-type flat key connection, which realizes the synchronous rotation and relative sliding between the first sleeve 7 and the second cylinder 4, that is, when the first sleeve 7 rotates, the second cylinder 4 can be driven to rotate synchronously through the keyway, and the second cylinder 4 can slide axially along the first sleeve 7 without driving the first sleeve 7 to move.

[0036] The second sleeve 9 extends out of the second cylinder 4 and the first sleeve 7 at one end close to the distribution disk 2. The outer side of the second sleeve 9 is threadedly connected to the second cylinder 4 and the inner side is threadedly connected to the third cylinder 5, that is, when the second sleeve 9 rotates, the second cylinder 4 and the third cylinder 5 both move synchronously along their axial directions, that is, when the second cylinder 4 and the third cylinder 5 move, their movement directions and movement distances are the same. The second sleeve 9 extends out of the end of the third cylinder 5 away from the distribution disk 2 and is fixedly connected to the third deformation disk 10 by the second deformation disk 8. The third cylinder 5 is key-connected to the through-core tube 1, and the specific connection method is a guide-type flat key connection, that is, the third cylinder 5 is circumferentially limited by the through-core tube 1, and the third cylinder 5 can slide axially along the through-core tube 1.

[0037] The first cylinder 3 is provided with a worm gear transmission mechanism and a bevel gear transmission mechanism, which respectively drive the first sleeve 7 and the second sleeve 9 to rotate. The worm gear transmission mechanism includes a worm wheel 11, a worm 12 and a connecting box 13. The connecting box 13 is fixedly provided on the outside of the first cylinder 3. The interior of the connecting box 13 is connected with the interior of the first cylinder 3. A worm 12 is rotated and penetrates the side wall of one side of the connecting box 13. A worm wheel 11 is fixedly sleeved on the outside of one end of the first sleeve 7 close to the distribution disk 2. The part of the worm 12 located in the connecting box 13 is meshed with the worm wheel 11. By rotating the worm 12, the worm wheel 11 is driven to rotate, the first sleeve 7 is driven to rotate, the second cylinder 4 is driven to rotate, and the second deformation disk 8 is driven to rotate, thereby realizing the rotation adjustment of the second deformation disk 8.

[0038] It should be noted that when the second deformable disk 8 is rotated and adjusted, its rotation angle usually does not exceed 10°. Therefore, since the second cylinder 4 and the second sleeve 9 inside it are threadedly connected, the second cylinder 4 undergoes a smaller range of axial movement when it rotates, which does not affect the production effect.

[0039] The bevel gear transmission mechanism includes a connecting column 14, a first bevel gear 15 and a second bevel gear 16. The connecting column 14 is passed through the outer side of the first cylinder 3 for rotation. One end of the connecting column 14 located in the first cylinder 3 is fixedly connected to the second bevel gear 16. When the connecting column 14 rotates, it drives the second bevel gear 16 to rotate. The first bevel gear 15 is fixedly provided on the end of the second sleeve 9 close to the distribution disk 2. The first bevel gear 15 is meshed with the second bevel gear 16. The second bevel gear 16 rotates, driving the first bevel gear 15 meshed with it to rotate, driving the second sleeve 9 to rotate, and then the second cylinder 4 and the third cylinder 5 threadedly connected to the second sleeve 9 move synchronously along their axial direction, so that the second deformation disk 8 and the third deformation disk 10 are close to or away from the first deformation disk 6.

[0040] As an implementable embodiment, a through hole can be opened at one end of the worm 12 and the connecting column 14 extending out of the first cylinder 3 (the through hole of the worm 12 is not shown in the figure). When adjusting, a pin shaft is inserted into the through hole to form a rotating handle, so that the worm 12 or the connecting column 14 can be conveniently rotated and adjusted.

[0041] The inner diameter of the first deformable disk 6 is smaller than the inner diameter of the first cylinder 3, and the first sleeve 7 is axially limited. An annular plate 17 is fixedly provided at the end of the first sleeve 7 away from the distribution disk 2. The inner diameter of the annular plate 17 is the same as that of the first sleeve 7, and the outer diameter is smaller than the outer diameter of the first sleeve 7. The annular plate 17 is located between the first deformable disk 6 and the second cylinder 4, that is, the annular plate 17 passes through the first deformable disk 6, and the first sleeve 7 and the second cylinder 4 are connected by a flat key. The keyway on the first sleeve 7 passes through the annular plate 17 to ensure that the second cylinder 4 moves smoothly when axial sliding occurs.

[0042] The second sleeve 9 includes a connecting sleeve and a matching sleeve. The connecting sleeve is fixedly connected to the matching sleeve at one end away from the distribution disk 2, and the inner diameter of the connecting sleeve is larger than the inner diameter of the matching sleeve. The inner diameter of the second deformable disk 8 is smaller than the second cylinder 4. An annular protrusion 18 is fixedly provided on the outer side of the third cylinder 5 near one end of the distribution disk 2. The outer diameter of the annular protrusion 18 matches the connecting sleeve. The matching sleeve is located between the annular protrusion 18 and the second deformable disk 8. When the second cylinder 4 and the third cylinder 5 move along their axial direction, if the moving direction is close to the distribution disk 2 and after moving a certain distance, the second deformable disk 8 will push against the end of the second sleeve 9 away from the distribution disk 2 to limit the movement of the second cylinder 4 and the third cylinder 5; if the moving direction is away from the distribution disk 2 and after moving a certain distance, the annular protrusion 18 will push against the end of the matching sleeve close to the distribution disk 2 to limit the movement of the second cylinder 4 and the third cylinder 5.

[0043] A bearing 19 is provided on the inner side of one end of the first sleeve 7 close to the distribution plate 2. The bearing 19 is sleeved on the second sleeve 9. The bearing 19 ensures the rotation between the first sleeve 7 and the second sleeve 9 to avoid the influence of their respective rotations.

[0044] The first deformable disk 6, the second deformable disk 8 and the third deformable disk 10 are each provided with a plurality of winding wheels 20 distributed along their respective circumferential directions and of equal number on their peripheral walls to bend the multiple strands of steel wire before twisting. The first deformable disk 6, the second deformable disk 8 and the third deformable disk 10 are all circular structures, and the diameters of the first deformable disk 6, the second deformable disk 8 and the third deformable disk 10 decrease successively. After passing through the wire hole 21 on the distribution disk 2, they are wound successively through the winding wheels 20 on the first deformable disk 6, the second deformable disk 8 and the third deformable disk 10. Each strand of steel wire is wound successively in a serpentine shape through the three winding wheels 20 to achieve pre-deformation.

[0045] During use, taking the production of 19-strand steel wire rope as an example, the rope core (twisted 7-strand steel wire rope) is passed through the distribution disk 2 and the core tube 1, and the 12 single-strand steel wires are respectively passed through a group of wire holes 21 on the distribution disk 2, and each steel wire corresponds to a wire hole 21. After the single-strand steel wire passes through the wire holes 21, it is wound in turn through the winding wheels 20 on the first deformation disk 6, the second deformation disk 8 and the third deformation disk 10. Each steel wire is wound in a serpentine shape through the three winding wheels 20 in turn, and then the 12 single-strand steel wires and the rope core are simultaneously passed through the wire closing mouth (not shown in the figure) to complete the plying.

[0046] When different pre-deformations of wire rope production are required, according to production requirements, the worm gear 11 can be driven to rotate by rotating the worm 12, which drives the first sleeve 7 to rotate, drives the second cylinder 4 to rotate, and drives the second deformation disk 8 to rotate, so as to realize the rotation adjustment of the second deformation disk 8, and thereby realize the deformation amount of the steel wire when it is serpentinely wound through the three winding wheels 20; the second bevel gear 16 can be driven to rotate by rotating the connecting column 14, and the rotation of the second bevel gear 16 drives the first bevel gear 15 meshing with it to rotate, and drives the second sleeve 9 to rotate, and then the second cylinder 4 and the third cylinder 5 threadedly connected to the second sleeve 9 move synchronously along their axial direction, so as to realize the second deformation disk 8 and the third deformation disk 10 approaching or moving away from the first deformation disk 6.

[0047] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
