Description

Technical Field

[0001] This utility model relates to the technical field of steel cord production equipment, specifically to a steel cord twisting and rope forming frame. Background Technology

[0002] In the current steel cord manufacturing process, especially when twisting steel cord into steel cord, a rope-forming frame is typically used to pull out multiple strands of cord through a collector, and then twist them into shape in a twisting machine. Existing DOF2 models require the selection of multiple different types of rope-forming frames to meet production needs when manufacturing cords with different structures. This necessitates factories purchasing and maintaining a large inventory of rope-forming frames to accommodate diverse production requirements. This current situation presents the following problems: 1. High equipment procurement and maintenance costs: In order to meet the production needs of steel cords with different structures, the factory has to purchase and maintain various types of rope forming frames, which leads to significant initial investment and ongoing operating costs.

[0003] 2. Complex production operations: Workers need to be familiar with and operate a variety of different rope-forming frames, which increases training needs and operational difficulty, and also increases the risk of operational errors and production accidents.

[0004] 3. Long production preparation and changeover time: Switching between different types of rope forming frames requires additional time, which leads to reduced production efficiency and potential capacity loss.

[0005] 4. Limited production flexibility and responsiveness: Due to the lack of rope forming frames that can adapt to various cord structures, the production line's flexibility and responsiveness in the face of market changes and customer demands are limited. Utility Model Content

[0006] To address the aforementioned technical problems, this technical solution provides a steel cord twisting and rope forming frame that integrates the functions of multiple rope forming frames, thereby reducing costs, simplifying operation procedures, and improving production efficiency; it can effectively solve the above problems.

[0007] This utility model is achieved through the following technical solution: A steel cord twisting frame includes a base, on which are mounted an integrated winding device, a splitter plate, and a coiling bracket arranged in the direction of steel cord travel. The coiling bracket has coiling holes. A groove is provided on the top surface of the base, and a deformation roller bracket is detachably and fixedly installed in the groove. Multiple pre-deformation rollers are fixed on the deformation roller bracket. A pre-deformation plate is detachably and fixedly installed at the center hole of the splitter plate. After being deformed by the pre-deformation rollers, the steel cord passes through the splitter plate and enters the coiling holes for stranding; or, after passing through the splitter plate, the steel cord is deformed by the pre-deformation plate and enters the coiling holes for stranding.

[0008] Furthermore, the integrated winding device includes an inner wire winding device and an outer wire winding device arranged on both sides of the chute. Both the inner wire winding device and the outer wire winding device include a front guide wheel assembly and a rear guide wheel assembly arranged in the forward direction of the steel cord. Both the front guide wheel assembly and the rear guide wheel assembly include an upper guide wheel and a lower guide wheel arranged vertically.

[0009] Furthermore, the upper guide wheel and the lower guide wheel are respectively mounted on the column by bearings, and a gap is provided between the upper guide wheel and the lower guide wheel, and an elastic retaining ring is provided in the gap to isolate the upper guide wheel and the lower guide wheel.

[0010] Furthermore, the integrated winding device also includes an upper wire feeding winding device installed on the upper side of the deformed roller support. The upper wire feeding winding device includes an upper wire feeding bracket fixed on the upper part of the deformed roller support. Multiple multi-groove guide wheels are installed on the top of the upper wire feeding bracket, and guide wheels are provided on the front and rear sides of the multi-groove guide wheels.

[0011] Furthermore, the multi-groove guide wheel is a three-groove large-diameter TRP wheel.

[0012] Furthermore, pre-deformed rollers are installed on both sides of the deformation roller bracket, and the outer layer of the pre-deformed rollers is provided with protrusions.

[0013] Furthermore, if the steel cord is deformed by a pre-deformation roller, the pre-deformation plate needs to be removed; if the steel cord is deformed by a pre-deformation plate, it does not pass through the pre-deformation roller.

[0014] Furthermore, the chute is provided with multiple fixing holes, and the deformable roller bracket, the wire distributor and the wire collector can be fixedly connected to any one or more fixing holes in the chute according to different needs.

[0015] Furthermore, both the splitter and the hub bracket have an "L" shaped structure on their sides. The bottom of the splitter has a slot that matches the bottom of the hub bracket, allowing the bottom of the hub bracket to be inserted into the bottom of the splitter. The bottom plate of the hub bracket has a through-hole in the middle.

[0016] Furthermore, the splitter is a six-hole splitter, including a central hole at the center and outer holes surrounding the central hole. Beneficial effects

[0017] The steel cord twisting rope frame proposed in this utility model has the following advantages compared with the prior art: This technical solution integrates the winding device into a single module, combining the inner, outer, and upper winding devices into a unified design. This allows the rope-forming frame to produce steel ropes composed of 2, 3, 4, or 5 strands of steel cord. Furthermore, the six-hole distributor allows for both directly twisted and ropes with a central shaft. A groove on the top surface of the base, along with detachable and fixed deformation roller supports, distributors, and collectors within the groove, allows for repositioning and adjustment to accommodate different types of steel rope, adapting to various specifications and structures of steel cord. Additionally, the multi-groove guide wheel in the upper winding device uses a three-groove, large-diameter TRP wheel, reducing additional deformation during the twisting process and improving the rope quality.

[0018] This technical solution integrates the functions of multiple rope-forming frames into one device, reducing the factory's need for multiple equipment and thus lowering procurement and maintenance costs. It can adapt to the production of steel cords of different specifications and structures; when changing to produce different specifications of steel cords, multiple production needs can be met without changing the rope-forming frame. This reduces the need to switch between different equipment, shortens production preparation and changeover time, and improves the flexibility and responsiveness of the production line. Operators can complete the production of different cord structures with simple adjustments, simplifying the operation process and reducing operational complexity. It also reduces worker training needs and operational complexity, improving production efficiency and safety.

[0019] This technical solution places the deformed roller support perpendicular to the horizontal plane, the pre-deformed roller parallel to the horizontal plane, and the pre-deformed roller and the guide wheel in the upper wire winding device on the same vertical plane. The pre-deformed roller, the guide wheel in the inner wire winding device and the outer wire winding device are on the same horizontal plane. This makes it easier for operators to wind the steel cord onto the pre-deformed roller, and makes the wire leading operation easier and more efficient, improving work satisfaction and production safety.

[0020] This technical solution can not only reduce costs, simplify operating procedures, and improve production efficiency, but also improve the quality of cord forming and the operability of the cord forming frame, thus bringing significant improvements and value to the steel cord manufacturing industry.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Various modifications and improvements to the technical solutions of the present utility model made by those skilled in the art without departing from the design concept of the present utility model should fall within the protection scope of the present utility model. Example

[0030] like Figure 1-7 As shown, a steel cord twisting rope frame includes a base 1, the base 1 includes a vertically arranged upright 11, the top of the upright 11 is integrally fixed with a horizontally arranged base plate 12, and a triangular reinforcing plate 13 is provided between the side of the upright 11 and the bottom surface of the base plate 12.

[0031] A slide groove 14 is provided on the top surface of the base 1, and multiple through holes for fixing are provided in the slide groove 14; the deformable roller bracket 2, the splitter plate 4 and the cable collector bracket 6 are detachably fixed in the slide groove 14 by means of screws and nuts; the deformable roller bracket 2, the splitter plate 4 and the cable collector bracket 6 can be fixedly connected to any one or more fixing holes in the slide groove 14 according to different needs.

[0032] Multiple pre-deformed rollers 3 are fixed on the deformation roller bracket 2. The multiple pre-deformed rollers 3 are installed on the inner and outer sides of the deformation roller bracket 2 through bearings. The outer layer of the pre-deformed roller 3 is provided with a protrusion 31. It can pre-deform the steel cord in the inner wire winding device 7, the outer wire winding device 8 and the upper wire winding device 9 respectively.

[0033] The cable distribution plate 4 is a six-hole cable distribution plate, including a central hole at the center and outer holes 41 surrounding the central hole. A pre-deformation plate 5 is detachably and fixedly installed at the central hole of the cable distribution plate 4 by means of a screw and nut; the outer edge of the pre-deformation plate 5 extends to the position of the outer holes 41. The steel cord passing through the outer holes 41 can be pre-deformed.

[0034] If the steel cord is deformed by the pre-deformation roller 3, the pre-deformation plate 5 must be removed; if the steel cord is deformed using the pre-deformation plate 5, it does not pass through the pre-deformation roller 3. This allows the steel cord to be deformed by the pre-deformation roller 3 first, then pass through the distributor 4 and enter the conductor hole 61 for stranding; alternatively, the steel cord can pass through the distributor 4 first, then be deformed by the pre-deformation plate 5 before entering the conductor hole 61 for stranding. The configuration is determined according to the production requirements of different steel rope models.

[0035] Alternatively, if production requires, the steel cord can be deformed by first passing through the pre-deformation roller 3, and after passing through the splitter plate 4, it can be deformed again by the pre-deformation plate 5, and finally enter the wire-gathering hole 61 for stranding; this method is also acceptable.

[0036] Both the splitter plate 4 and the hub bracket 6 have an "L"-shaped structure on their sides. The bottom of the splitter plate 4 has a slot 42 that matches the bottom of the hub bracket 6, allowing the bottom of the hub bracket 6 to be inserted into the bottom of the splitter plate 4. The center of the hub bracket's base plate has a through-hole 62, allowing the hub bracket 6 to shift relative to the splitter plate 4 along the direction set by the slot. This allows the spacing between the cable threading holes on the splitter plate 4 and the cable gathering holes 61 on the hub bracket 6 to be adjusted.

[0037] An integrated winding device is installed on the base 1 in the direction of steel cord advance. The integrated winding device includes an inner winding device 7 and an outer winding device 8 arranged on both sides of the slide 14, and an upper winding device 9 installed on the upper side of the deformed roller support 2.

[0038] Both the inner wire winding device 7 and the outer wire winding device 8 include a front guide wheel assembly and a rear guide wheel assembly arranged in the forward direction of the steel cord; each of the front guide wheel assembly and the rear guide wheel assembly includes an upper guide wheel and a lower guide wheel arranged vertically. The upper guide wheel and the lower guide wheel are respectively mounted on the column by bearings, and a gap is provided between the upper guide wheel and the lower guide wheel, and an elastic retaining ring is provided in the gap to isolate the upper guide wheel and the lower guide wheel.

[0039] The upper wire feeding and winding device 9 includes an upper wire feeding bracket 91 fixed to the upper part of the deformed roller bracket 2 by a nut and screw assembly. Multiple multi-groove guide wheels 92 are installed on the top of the upper wire feeding bracket 91. The multi-groove guide wheels are three-groove large-diameter TRP wheels. Guide wheels 93 are provided on the front and rear sides of the multi-groove guide wheels 92.
