Description

Technical Field

[0001] The present application relates to the technical field of steel wire rope production equipment, and in particular to a triangular strand steel wire rope forming device. Background Art

[0002] In recent years, the application field of triangular strand wire rope has been continuously expanding. It is not only used in the mining and metallurgical industry, but has also been successfully applied to cableways, petroleum, engineering ships and other fields. The triangular strand wire rope strands are mainly produced by a special stranding machine to produce strands with a triangular cross-section shape, and then they are extruded by a professional rotary molding device on a rope forming machine and twisted into wire ropes.

[0003] In the prior art, such as the patent CN202730522U, a closed twisting and forming device for triangular stranded steel wire rope is disclosed. In this patent, three pressure rollers are installed on the three sliders of the three-jaw chuck, and then the steel wire rope strands are compressed by the triangular cavity formed by the three pressure rollers. During use, the movement of the three sliders is used to adapt to triangular strands of different specifications and models. However, it still has the following shortcomings: the thickness of the pressure roller is certain, so for thicker triangular rollers, the contact area between the pressure rollers and the triangular rollers will be small, thereby affecting the extrusion effect; if it is for thinner triangular rollers, there may be interference between adjacent pressure rollers, which will also affect the extrusion effect. For this reason, a triangular stranded steel wire rope forming device is proposed to solve the above technical problems. Utility Model Content

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] One of the preferred embodiments of this application is as follows: Figures 1 to 5 As shown, a triangular strand steel wire rope forming device includes a three-jaw chuck 1, (three) turntables 4 and a limit assembly 5, wherein the turntable 4 is rotatably mounted on the slider 101 of the three-jaw chuck 1, and a plurality of pressure rollers 3 are arranged on the outside of the turntable 4, and the limit assembly 5 is arranged between the turntable 4 and the slider 101.

[0025] It is understandable that among the multiple pressing rollers 3 outside the turntable 4, the model and size of each pressing roller 3 are different. Therefore, when pre-pressing and deforming the steel wire rope strands according to different conditions, we can adjust the model of the pressing roller 3, such as Figure 2 As shown, first release the lock of the turntable 4 through the limit assembly 5, then the turntable 4 can be rotated, and then the corresponding (three) pressure rollers 3 are adjusted to the corresponding positions; when the adjustment is completed, the turntable 4 can be locked through the limit assembly 5.

[0026] It should be noted that the specific structure and working principle of the three-jaw chuck 1 are common knowledge known to those skilled in the art, and therefore will not be described in detail here.

[0027] As a further description of the above embodiment: the limiting component 5 has various structural forms, including but not limited to the following two:

[0028] Structure 1 (not shown): can refer to Figure 4 The limiting assembly 5 includes a limiting screw and a plurality of limiting grooves 502 . The limiting screw cooperates with the turntable 4 through threads. The limiting grooves 502 are provided on the slider 101 , and the limiting screw cooperates with the limiting grooves 502 .

[0029] It is understood that when adjustment is required, the limit screw is spirally rotated to move the limit screw until it disengages the limit slot 502, thereby releasing the lock on the turntable 4. Similarly, after the adjustment is completed, the limit screw is spirally rotated in the opposite direction until it abuts against the limit slot 502, thereby locking the turntable 4.

[0030] Structure 2 (such as Figure 4 As shown): The limiting assembly 5 includes a limiting rod 501 and a plurality of limiting slots 502. The limiting rod 501 is elastically slidably installed on the top of the turntable 4 (through a spring), and the limiting slot 502 is set on the slider 101. The limiting rod 501 cooperates with the limiting slot 502.

[0031] It is understandable that when adjustment is required, the limit rod 501 is pulled out and away from the limit slot 502 to release the lock of the turntable 4. Similarly, after the adjustment is completed, the limit rod 501 is released and the spring force of the spring causes the limit rod 501 to insert into the limit slot 502 and cooperate with it, thereby locking the turntable 4.

[0032] Furthermore, we know that there are three sliders 101 in the three-jaw chuck 1, and we can also set the number of the limiting rods 501 and the limiting grooves 502 to three, and the two are distributed at equal distances along the axis of the turntable 4. This can ensure the stability and accuracy of the turntable 4 during the adjustment process. Of course, in order to facilitate the synchronous movement (movement) of multiple limiting rods 501, a fixed block 6 can be fixedly installed on the top of the multiple limiting rods 501, and a pull ring 7 is provided on the top of the fixed block 6. In this way, when operating, we can pull out all the limiting rods 501 through the pull ring 7 to improve convenience. It should be known that the above-mentioned limiting screw adopts the method of threaded engagement, so for the sake of convenience, it is not recommended to use multiple here, and the stability of the threaded engagement itself is relatively high, so using one can meet actual needs.

[0033] During the above adjustment process, we know that when the limiting rod 501 (or limiting screw) cooperates with the limiting groove 502, it represents the corresponding positions of the three pressing rollers 3. However, in the actual adjustment process, it may take a certain amount of time to find the adjusted position, thereby affecting work efficiency.

[0034] Therefore, in order to solve the above technical problems, Figure 5 As shown, a column 8 is installed on the top of the slider 101, and the turntable 4 is rotatably installed on the top of the column 8, and the turntable 4 and the column 8 are matched through a clutch structure 9.

[0035] It can be understood that when the turntable 4 is rotated and adjusted to the set position, the clutch structure 9 is in a limited state, thereby limiting the turntable 4 (pre-positioning), so that the position to be locked after the turntable 4 is adjusted can be quickly limited, thereby providing convenience for the subsequent locking of the turntable 4.

[0036] The present application does not limit the specific structure of the clutch structure 9. A specific embodiment is provided below for description:

[0037] like Figure 5 As shown, the clutch structure 9 includes a clutch block 901 and a plurality of clutch slots 902. The clutch slots 902 are provided outside the column 8. The clutch block 901 is elastically slidably mounted (via a spring) in the turntable 4. The clutch block 901 can be spherical, and the clutch slots 902 can be hemispherical.

[0038] It should be noted that when the clutch block 901 is engaged with the clutch slot 902, the clutch structure 9 is in a limited position, that is, the limit rod 501 (or limit screw) is in a positive correspondence with the corresponding limit slot 502. When the turntable 4 is adjusted, the clutch block 901 will slide and forcibly separate from the clutch slot 902.

[0039] In this embodiment, Figure 1 As shown, to facilitate protection of the unused pressure rollers 3, a protective shell 2 can be installed on the slider 101. Therefore, after adjustment is completed, the remaining pressure rollers 3 are located within the protective shell 2, while the active pressure rollers 3 are located outside the protective shell 2. This effectively prevents unnecessary wear or damage to the unused pressure rollers 3 during operation. Specifically, the protective shell 2 can be designed as a semi-enclosed design to facilitate installation and removal of the pressure rollers 3 while also providing adequate protection.

[0040] The working principle of this utility model is:

[0041] First, we can assume that there are three pressure rollers 3 on the turntable 4, and each pressure roller 3 is of a different model. The models of the pressure rollers 3 of the three turntables 4 near the center of the three-jaw chuck 1 are corresponding. The steel wire rope passes through the corresponding three pressure rollers 3. Then, by adjusting the three-jaw chuck 1, the relative distance between the three pressure rollers 3 can be adjusted, thereby achieving the adjustment of the extrusion force of the steel wire rope; when it is necessary to replace the steel wire rope of different models for extrusion, it is necessary to adjust the corresponding pressure roller 3 to the center position of the three-jaw chuck 1. First, the limit rod 501 is pulled out from the limit groove 502 by the pull ring 7 to release the limit on the turntable 4. Then, the turntable 4 is rotated and the corresponding pressure roller 3 is rotated close to the center of the three-jaw chuck 1. At this time, the clutch block 901 cooperates with the clutch groove 902 to pre-position the adjusted position. Finally, after releasing the limit rod 501, the limit rod 501 will be inserted into the limit groove 502 under the elastic force of the spring to cooperate with it, thereby locking the turntable 4 and completing the adjustment.

[0042] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought.
