Description

Technical Field

[0001] The utility model relates to the technical field of steel strand twisting, in particular to a segmented pitch-adjustable twisting wire contact steel strand dividing disc. Background Art

[0002] During the twisting process of steel strands, in order to make the side wires close around the center wire evenly, regularly and orderly, and each steel wire enters its own strand layer, a wire distribution disc tooling is required. The process is highly applicable and has high process requirements.

[0003] The existing technology of the distribution plate structure used in the production of steel strands in the industry is the equipment connection part + the main part of the distribution plate. The function of the equipment connection part is to assemble the distribution plate body with the connected equipment; the main part is processed with wire holes, and the steel wire is evenly distributed according to the process requirements. The number and distribution parameters of the wire holes are different for different steel strand structures, which are calculated and determined according to the design principles. The distribution plate is divided into two parts from a functional perspective: the equipment connection part + the main part of the distribution plate, but the distribution plate is an integral assembly, which requires safety and stability in continuous rotation and coaxiality within the design tolerance range. However, it was found in the study that the wire splitter in the prior art is very smooth in twisting 1×7, 1×19 and other point contact structural steel strands, but for line contact structural steel strands, such as 19S, 19W, 26WS, 31WS, 36WS, etc., if the wire splitter in the prior art is used in the production line contact structural steel strand process, due to the 2 or 3 closing points, a wire splitter mold is required. The wire splitter mold is a small annular mold that separates the closing points and forces the steel wires to enter the corresponding positions of each strand layer and close smoothly. However, the steel strands will heat up after a long time of use, and the temperature increase will easily lead to zinc layer oxidation and strand breakage; in addition, the wire splitter mold is also prone to cause frequent riding of the steel strands, disordered structure, and very low production efficiency. Therefore, the wire splitter in the prior art has great limitations and is not suitable for application in the field of line contact steel strands. Therefore, how to overcome the problems brought about by the existing wire splitter is a technical problem that technicians in this field urgently need to solve. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a wire dividing disk for twisting wires in contact with steel strands with adjustable segmented pitch. The wire dividing disk of the utility model replaces wire dividing by segmented twisting, thereby improving the friction and heating of the wire strands, reducing the oxidation of the zinc layer, and reducing the number of strand breakages and the probability of product failure accidents such as structural disorder and steel strand riding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wire distribution plate for contacting steel strands with segmented adjustable distance, comprising: an equipment connection assembly, a wire distribution plate body and a plurality of fixed shafts;

[0007] The main body of the distribution board includes a front distribution board, a middle distribution board and a rear distribution board, and the front distribution board, the middle distribution board and the rear distribution board are fixedly connected by a plurality of fixed shafts; a connecting shaft is fixedly connected at the center position of the bottom surface of one side of the equipment connection component, and the equipment connection component is connected to the rear distribution board through the connecting shaft; the front distribution board, the middle distribution board and the rear distribution board are provided with wire passing holes evenly distributed along the circumference, and the wire passing holes specifically include at least one of the first wire passing hole, the second wire passing hole or the third wire passing hole.

[0008] As a further technical solution, the first wire passing hole, the second wire passing hole and the third wire passing hole are evenly distributed along the circumference of the rear wire dividing disk, the distance from the first wire passing hole to the center of the rear wire dividing disk is greater than the distance from the second wire passing hole to the center of the rear wire dividing disk, and the distance from the second wire passing hole to the center of the rear wire dividing disk is greater than the distance from the third wire passing hole to the center of the rear wire dividing disk.

[0009] As a further technical solution, the first wire passing holes and the second wire passing holes are evenly distributed along the circumference of the center wire dividing disk, and the distance from the first wire passing holes to the center of the center wire dividing disk is greater than the distance from the second wire passing holes to the center of the center wire dividing disk.

[0010] As a further technical solution, the first wire passing holes are evenly distributed along the circumference of the front wire distribution plate.

[0011] As a further technical solution, three first fixing holes are equidistantly arranged on the outer circumference of the front dividing disk, three second fixing holes are equidistantly arranged on the outer circumference of the middle dividing disk, and three third fixing holes are equidistantly arranged on the outer circumference of the rear dividing disk.

[0012] As a further technical solution, the first fixing hole, the second fixing hole and the third fixing hole are aligned.

[0013] As a further technical solution, the fixing shaft passes through the first fixing hole, the second fixing hole and the third fixing hole in sequence, and the front distribution plate, the middle distribution plate and the rear distribution plate are fixedly connected by nuts.

[0014] As a further technical solution, the wire passing hole is welded with a wire passing nozzle, and the wire passing nozzle matches the wire passing hole.

[0015] As a further technical solution, the wire passing nozzle is made of hard alloy material.

[0016] As a further technical solution, the diameter of the wire passing nozzle is larger than the diameter of the steel strand.

[0017] One or more technical solutions of the utility model have the following beneficial effects:

[0018] (1) The utility model is safe and stable during the twisting process of steel strands. By designing the front dividing disk, the middle dividing disk and the rear dividing disk, segmented twisting is realized, replacing the dividing mode in the prior art, so that the closing points are sequentially separated by a longer distance, improving the friction and heat generation of the wire strands, reducing the oxidation of the zinc layer, reducing the number of strand breaks and the probability of product failure accidents such as structural disorder and steel strand riding, thereby improving product quality.

[0019] (2) The utility model sets a fixed shaft to fix the front wire distribution disk, the middle wire distribution disk and the rear wire distribution disk in connection, and fixes the front wire distribution disk, the middle wire distribution disk and the rear wire distribution disk in connection through nuts, and locks the front wire distribution disk, the middle wire distribution disk and the rear wire distribution disk with nuts. Loosening the nuts can adjust the distance between the front wire distribution disk, the middle wire distribution disk and the rear wire distribution disk, i.e., the distance, to meet the distance requirements of steel strand production with different processes, and the distance is equal to the closing distance. This makes the twisting of steel strands more scientific and the process parameters more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] Embodiment 1

[0029] like Figure 1 and 5As shown, the utility model provides a segmented and adjustable distance twisting wire contact steel strand distribution plate, comprising: an equipment connection assembly, a distribution plate body and a plurality of fixed shafts; wherein the distribution plate body comprises a front distribution plate, a middle distribution plate and a rear distribution plate, and the front distribution plate, the middle distribution plate and the rear distribution plate are fixedly connected by a plurality of fixed shafts, specifically: three first fixing holes are provided at equal intervals on the outer circumference of the front distribution plate, three second fixing holes are provided at equal intervals on the outer circumference of the middle distribution plate, and three second fixing holes are provided at equal intervals on the outer circumference of the rear distribution plate. Three third fixing holes are set at equal intervals; the positions of the first fixing hole, the second fixing hole and the third fixing hole are aligned, the fixing shaft passes through the first fixing hole, the second fixing hole and the third fixing hole in sequence, and the front, middle and rear dividing disks are fixedly connected by nuts, and the front, middle and rear dividing disks are locked with nuts. The distance between the front, middle and rear dividing disks, i.e. the distance, can be adjusted by loosening the nuts to meet the distance requirements of steel strand production with different processes, and the distance is equal to the closing distance. This makes the twisting of steel strands more scientific and the process parameters more accurate.

[0030] like Figure 1 As shown, a connecting shaft is fixedly connected to the center position of the bottom surface of one side of the equipment connection component, and the equipment connection component is connected to the rear distribution plate through the connecting shaft; the rear distribution plate is set according to the actual situation of the equipment connection component to ensure stable and reliable connection.

[0031] like Figure 1 As shown, the front wire dividing disk, the middle wire dividing disk and the rear wire dividing disk are provided with wire passing holes evenly distributed along the circumference, and the wire passing holes specifically include at least one of the first wire passing hole, the second wire passing hole or the third wire passing hole. Specifically: the wire passing holes on the rear wire dividing disk are evenly distributed along the circumference of the first wire passing hole, the second wire passing hole and the third wire passing hole, the distance from the first wire passing hole to the center of the rear wire dividing disk is greater than the distance from the second wire passing hole to the center of the rear wire dividing disk, and the distance from the second wire passing hole to the center of the rear wire dividing disk is greater than the distance from the third wire passing hole to the center of the rear wire dividing disk; the first wire passing holes and the second wire passing holes are evenly distributed along the circumference on the middle wire dividing disk, the distance from the first wire passing hole to the center of the middle wire dividing disk is greater than the distance from the second wire passing hole to the center of the middle wire dividing disk; the first wire passing holes are evenly distributed along the circumference on the front wire dividing disk. In this embodiment, the front disk center wire passing hole, the middle disk center wire passing hole and the rear disk center wire passing hole are respectively provided at the center positions of the front wire dividing disk, the middle wire dividing disk and the rear wire dividing disk.

[0032] In this embodiment, the wire hole is welded with a wire nozzle, the wire nozzle matches the wire hole, and the wire nozzle is made of cemented carbide material with a hardness of HRC>60 and a roughness of Ra0.2. In addition, in order to improve applicability, the diameter of the wire nozzle is determined by comprehensively considering the steel strand process in a certain diameter range, and the median of the wire nozzle diameter range is used as the name of the wire distribution plate. For example, the name of the steel strand distribution plate for producing 36WS structure and diameter range of 6.5mm-8.5mm is 36WS / 7.5.

[0033] Taking the 36WS / 7.5 three-section wire distribution disk as an example, the front wire distribution disk, the middle wire distribution disk and the rear wire distribution disk are processed with wire holes, and the wire holes are welded with alloy wire nozzles. The three-section wire distribution disk is closed at three closing points. The closing distance d is calculated according to the steel strand twist pitch, d = 2.8S (S: twist pitch) and adjusted appropriately. The diameter R of the distribution circle of the wire holes is calculated according to the closing distance d and the steel strand twist angle α, R = d × tanα and adjusted appropriately. The diameter of the wire nozzle at the center of each disk is calculated and determined according to the wire strand diameter and production experience. If the diameter is too small, zinc is easily accumulated, and if it is too large, it is not easy to close. It is generally 1.3 to 1.7 times the strand diameter (Note: the strand diameter here is the strand diameter after closing at the current closing point). It is worth noting that the above process is not the protection point of the utility model, and the above process is the prior art.

[0034] In order to improve the friction and heating of wire strands, reduce the oxidation of zinc layer, reduce the number of strand breakage and the probability of product failure caused by structural disorder and steel strand riding, as well as improve the versatility of the device and ensure the stability of the distribution plate, the following methods are mainly used:

[0035] Three-layer segmented twisting:

[0036] like Figure 2 As shown in the figure, the rear distribution plate is designed with 1-7-7 / 7-14 distribution holes. The innermost 7 steel wires of the steel strand are closed at the center hole of the middle plate, which is the first closing point. The first and second holes of the rear distribution plate are only for passing wires but not closed. Figure 3 As shown in the figure, the center wire tray is designed with 7 / 7-14 distribution wire holes. The 14 steel wires in the second outer layer of the steel strands are closed at the center wire hole of the front tray, which is the second closing point. The first wire hole of the center wire tray only passes wires but does not close. Figure 4 As shown in the figure, the front wire distributor is designed with 14 first wire holes, so that the outermost wire is closed at the closing point in front of the front wire distributor, which is the final closing point. At this time, the steel wire is closed and the steel strand is formed. Here, it should be explained that the outermost wire will form a final closing point in front of the front disk (outward in the axial direction), and the outer steel wire is forced to close at the final closing point by the wire pressing die seat (the next tooling of the wire distributor).

[0037] The utility model is safe and stable in the production process, adopts a three-stage twisting mode instead of using a split wire mold, so that the closing points are sequentially separated by a relatively long distance, improves the friction and heating of the wire strands, reduces the oxidation of the zinc layer, reduces the number of strand breakages and the probability of product failures caused by structural disorder and steel strand riding, and improves product quality. The utility model has adjustable distance to meet the distance required for steel strand production with different processes, makes the steel strand twisting more scientific, and makes the process parameters more accurate.

[0038] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
