Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel cord production, in particular to a pre-deformer used for twisting steel cord. Background Art
[0002] In the production process of steel cord, pre-deformation components play an extremely important role. The monofilaments that meet the requirements are twisted into ropes at the rope mouth through the pay-off and wire-passing components in the cord plying equipment. In order to ensure the twisting quality and remove a certain amount of stress from the cord before rope formation, most cords require pre-deformation components. Pre-deformation is performed before the monofilaments are roped. The regularly deformed monofilaments are tightly twisted together to form a rope, which not only improves the twisting quality of the cord, but also has a certain effect on eliminating the cord stress.
[0003] Existing deformers, such as that shown in Patent Document 1, include a main fixed disk with multiple wire-passing shafts on the fixed disk. Pre-deformation occurs when the steel wire passes around the wire-passing shafts. The amount of deformation can be changed by adjusting the relative position between each shaft. This type of deformer is not flexible to adjust, has a single adjustment method, has almost no adjustable points, and the deformation effect varies depending on the specifications.

[0026] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.
[0027] Combine Figure 1 and Figure 2 As shown, the first aspect of the utility model proposes a pre-deformer for twisting steel cord, including a support plate 10, a wire passing plate 20 and a pre-deformation component 30, the support plate 10 is provided with a circular groove, the support plate 10 is threadedly connected with a fastening screw 11, and the fastening screw 11 can extend into the circular groove; the wire passing plate 20 is connected to the circular groove and fixed by the fastening screw 11, and a plurality of wire passing nozzles 22 are provided on the wire passing plate 20.
[0028] The outer wall of the wire passing plate 20 is constructed with a circular profile and can fit in the circular groove. Therefore, the wire passing plate 20 can rotate freely, so that the position of each wire passing nozzle 22 on the wire passing plate 20 changes. When the fastening screw 11 is tightened, the relative position of the wire passing plate 22 and the support plate 10 is fixed, and the position of the wire passing nozzle 22 is determined.
[0029] Furthermore, the pre-deformation component 30 is connected to the support plate 10 , and the pre-deformation component 30 is constructed as a polyhedron structure, with each face being provided with a row of deformation pins 32 .
[0030] The wires are guided by the wire passing wheel from the wire passing nozzle 22 through the wire passing plate 20 and then pre-deformed by the deformation needle 32 .
[0031] Since the wire passing plate 20 can be rotated relative to the support plate 10, the position of each wire passing nozzle 22 is rotated at a predetermined angle around the axis of the circular groove, and the fastening screw 11 can press the wire passing plate 20 so that the wire passing plate 20 and the support plate 10 are relatively fixed. Therefore, by changing the angle of the wire passing plate 20, the steel wire is deformed when passing through the wire passing nozzle 22, that is, the first pre-deformation is generated by the wire passing nozzle 22. After passing through the wire passing nozzle 22, the steel wire bypasses each deformation needle 32 in turn, and the steel wire can also be deformed by passing through the deformation needle 32, so that the steel wire is pre-deformed for the second time.
[0032] Therefore, there are two adjustment factors that can change the deformation of the steel wire, which is more flexible and changeable than traditional pre-deformation components, and has a better effect on improving cord twisting and stress relief.
[0033] Combine Figure 3 As shown, a mounting plate 12 is provided at the bottom of the support plate 10, and a wire passing area is formed above the mounting plate 12. The mounting plate 12 is perpendicular to the support plate 10. The support plate 10 is installed on the wire feeding side of the twisting equipment. A strip groove is provided in the middle of the mounting plate 12, and a fastening nut is provided in the strip groove to fix the mounting plate 12 in a suitable position.
[0034] It should be understood that a guide wheel for conveying the steel wire is provided on the side of the mounting plate 12 away from the support plate 10. The starting point of the steel wire from the guide wheel is fixed. After being led out from the guide wheel, the steel wire conveyed from above the mounting plate 12 passes into the wire mouth 22. Therefore, its terminal position of conveyance is determined by the wire mouth 22. By changing the position of the wire mouth 22, the angle of the steel wire with the wire mouth 22 during conveyance can be changed differently, and based on this change, the pre-deformation amount of the steel wire can be changed.
[0035] Combine Figure 4a and Figure 4b As shown, when the wire passing plate 20 is in the first position, the angle between the steel wire and the wire passing nozzle 22 is A, and when the wire passing plate 20 is in the second position, the angle between the steel wire and the wire passing nozzle 22 is B. As the angle between the steel wire and the wire passing nozzle 22 changes, the deformation of the steel wire also changes.
[0036] In an optional embodiment, the wire passing nozzle 22 is made of a wear-resistant alloy material, such as tungsten steel, and the wire inlet and outlet ends of the wire passing nozzle 22 are both configured to be bell-mouth shaped for smooth contact with the steel wire.
[0037] Furthermore, the outer wall of the wire plate 20 is provided with a connecting ring 21, and the outer wall of the connecting ring 21 is provided with a protrusion structure. When adjusting the position of the wire plate 20, the fastening screw 11 is first loosened, and then the protrusion structure of the connecting ring 21 is pressed against the wire plate 20 by a tool or by hand, and the wire plate 20 is rotated until the target angle is reached.
[0038] Optionally, the protruding structure includes a pair of orifice plates, and the relative positions of the pair of orifice plates and each wire passing nozzle 22 are fixed.
[0039] It can be understood that the protruding structure not only serves as a force application point for external force when rotating the wire-passing plate 20 , but also serves as an indicator of the rotation angle of the wire-passing plate 20 .
[0040] Combine Figure 1 and Figure 2As shown, the pre-deformation component 30 includes multiple deformation surfaces, the edges of the multiple deformation surfaces are closed to form a regular polygon, and the width of each deformation surface of the pre-deformation component 30 gradually narrows along the line direction. A row of linearly arranged deformation pins 32 is provided on the deformation surface.
[0041] Among them, each deformation surface corresponds to a wire passing nozzle 22, and the steel wire led out from the wire passing nozzle 22 passes around each deformation needle 32 in turn. The serpentine winding allows the steel wire to relieve stress when passing through and at the same time causes the steel wire to have a certain pre-deformation.
[0042] Furthermore, the pre-deformation component 30 is constructed to include a plurality of polyhedron plates 31 arranged along the axial direction, the side of the polyhedron plate 31 is provided with a plurality of deformation surfaces, each deformation surface is provided with a deformation needle 32, and the plurality of polyhedron plates 31 are fixed to the wire plate 20 by fixing bolts 33.
[0043] Specifically, a screw hole 23 is provided in the middle of the wire passing plate 20, and a fixing bolt 33 is threadedly connected in the screw hole 23. When the fixing bolt 33 is tightened, the multiple polyhedron plates 31 are pressed together and relatively fixed. When the fixing bolt 33 is loosened, the polyhedron plates 31 can rotate relative to each other to adjust the relative angle.
[0044] The polyhedron plate 31 can rotate relative to the fixing bolt 33 , so that the relative positions of the deformation pins 32 change.
[0045] In this way, by controlling the relative angle of each polyhedron plate 31, the positions of the two adjacent deformation needles 32 are changed, and the degree of bending of the steel wire when it passes around the deformation needle 32 also changes. Therefore, by controlling the relative position of each polyhedron plate 31, the pre-deformation amount of the steel wire can be changed.
[0046] In combination with the above embodiments, the wire passing plate of the utility model can rotate relative to the support plate. A pre-deformation component is provided on one side of the wire passing plate, and a wire passing nozzle is provided on the wire passing plate. The steel wire passes through the wire passing nozzle and the deformation needle on the pre-deformation component in turn to achieve stress relief and pre-deformation. The steel wire produces the first pre-deformation when passing through the wire passing plate and the second pre-deformation when passing through the deformation needle. The two pre-deformations make the steel wire produce a better stress relief effect, improve the twisting effect of the steel cord, and this pre-deformer is highly adjustable, more flexible and changeable, and can adapt to the pre-deformation processing of different products.
[0047] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
