Abstract
Description
Technical Field
[0001] This application relates to the field of steel cord processing technology, and in particular to a double-sided bearing deformer for an internal wire twisting machine. Background Technology
[0002] In the production and processing of steel strands, the steel wires undergo an important pre-treatment step before twisting—pre-deformation using a deformer. This process aims to ensure that the tension of each wire remains consistent during subsequent twisting by bending and deforming the steel wire, thereby preventing looseness in the finished steel strands. The core mechanism of the deformer is to use guide rollers to guide the steel wires and apply the pre-deformation effect.
[0003] Currently, most deformer shafts are designed with a cantilever structure, where one end of the shaft is fixed to the deformer frame by a bearing, while the other end is suspended in the air. However, this design faces some challenges in practical applications. Especially in the environment of an internal wire feeding twister, due to space constraints in the wire feeding cradle, the deformer design is very compact, and the bearings used are relatively small. During the steel strand production process, the steel wire exerts continuous pressure on the bearings, accelerating bearing wear and significantly shortening the lifespan of the smaller bearings. This not only increases the frequency and cost of equipment maintenance but also directly affects overall work efficiency.
[0004] Furthermore, during the pre-deformation process of the steel wire through the guide rollers, the wire may become loose or jump, leading to a risk of the wire accidentally detaching from the deformer. This detachment disrupts the continuous pre-deformation process of the wire, making it impossible to maintain consistent tension during twisting, ultimately affecting the forming quality and overall performance of the steel strand. Utility Model Content
[0005] The purpose of this application is to provide a double-sided bearing deformer for an internal wire feeding twisting machine, which solves the problem that the bearing life of the deformer on the wire feeding cradle of the existing internal wire feeding twisting machine is short and that the steel wire will detach during the pre-deformation process.
[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0007] On one hand, this application provides a double-sided bearing deformer for an internal wire twisting machine, comprising:
[0008] Support plate;
[0009] A deformable assembly, comprising multiple deformable assemblies circumferentially equidistantly arranged on the side of a support plate, including: a deformer frame connected to the support plate, having an assembly groove thereon, bearing holes oppositely arranged on both sides of the assembly groove, a first bearing and a second bearing respectively disposed in the two bearing holes, a deformer shaft disposed in the assembly groove, and the two ends of the deformer shaft being rotatably connected to the first bearing and the second bearing respectively;
[0010] The support plate serves as the basic support structure, ensuring the stability and accuracy of the deformation components. The wire gathering assembly is used to collect the pre-deformed steel wires. Multiple deformation components are circumferentially distributed on the support plate, ensuring uniform output of multiple pre-deformed steel wires.
[0011] During the pre-deformation process of the steel wire, the steel wire generates radial pressure on the deformer shaft. This radial pressure is evenly distributed on the first and second bearings located on both sides of the deformer shaft. Compared to the traditional cantilever structure deformer shaft, the radial force borne by each bearing in this design is only half that in the traditional cantilever structure, thus significantly extending the service life of the bearings. Furthermore, in this design, the steel wire is always positioned between the deformer shaft and the assembly groove, effectively avoiding the risk of detachment from the deformer due to loosening or jumping, thereby further improving the reliability and safety of the entire deformation process.
[0012] Optionally, the deformer shaft includes a deforming wheel and a rotating shaft protruding from both ends of the deforming wheel on the axial side.
[0013] Optionally, the deformation wheel has a groove arranged around its center. The groove provides a defined path for the steel wire, allowing it to travel along a predetermined trajectory during deformation. This helps reduce swaying and misalignment of the steel wire during deformation, thereby improving the accuracy and consistency of the deformation. It also ensures that the radial pressure on the first and second bearings is evenly distributed, extending the bearing's service life.
[0014] Optionally, it also includes a guide, which is disposed on the deformer frame and used to guide the steel wire into the deformation assembly. The guide being disposed on the deformer frame maximizes the use of the space in the wire feeding cradle of the inner wire feeding twister.
[0015] Optionally, it also includes a wire gathering nozzle. The wire gathering assembly (3) and the guide wheel (4) are disposed on the same side of the support plate (1), including: a wire gathering nozzle frame (31) and a wire gathering nozzle (32) disposed on the wire gathering nozzle frame (31). The wire gathering nozzle (32) is at the same distance from the plurality of deformation components (2). In this scheme, the wire gathering nozzle is at the same distance from the plurality of deformation components, ensuring that each steel wire can enter the wire gathering nozzle at the same path and angle after passing through the deformation components, thereby ensuring the uniformity and consistency of the steel wire.
[0016] Optionally, it also includes a base, which is disposed inside the wire feeding cradle of the inner wire feeding twister and is used to support the support plate and the wire gathering assembly.
[0017] Compared with the prior art, the beneficial effects achieved by this application are as follows:
[0018] In this invention, the two ends of the deformer shaft are rotatably connected to the deformer frame. The radial pressure generated by the steel wire on the deformer shaft is evenly distributed to the first and second bearings located on both sides of the deformer shaft. Compared with the traditional cantilever structure deformer shaft, the radial force borne by each bearing in this design is only half that in the traditional cantilever structure, thereby significantly extending the service life of the bearings and reducing maintenance and replacement costs. Furthermore, the steel wire in this design is always located between the deformer shaft and the assembly groove, effectively avoiding the risk of detachment from the deformer shaft due to loosening or jumping, further improving the reliability and safety of the entire deformation process.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0025] Example 1
[0026] This embodiment describes a double-sided bearing deformer device for an internal wire-feeding twisting machine, referencing... Figure 1 and Figure 2 ,in Figure 2 This includes a semi-perspective view of the deformation components. The double-sided bearing deformer of the internal wire twisting machine in this embodiment includes a support plate 1 and multiple deformation components 2 circumferentially and equidistantly arranged on the side of the support plate 1. The support plate 1 serves as the basic support structure, ensuring the stability and accuracy of the deformation components 2. The multiple deformation components 2 are circumferentially and equidistantly distributed on the support plate 1, ensuring uniform output of multiple steel wires after pre-deformation. Further, the deformation component 2 includes: a deformer frame 21, connected to the support plate 1, with an assembly groove 211 on it. Bearing holes are provided on both sides of the assembly groove 211, with a first bearing 222 and a second bearing 223 respectively installed in the two bearing holes. A deformer shaft 22 is provided within the assembly groove 211, with both ends of the deformer shaft 22 rotatably connected to the first bearing 222 and the second bearing 223 respectively. The deformer shaft 22 is used for pre-deforming the steel wire. Further, a guide wheel 4 is also provided on one side of the deformer shaft 22 to guide the steel wire correctly into the deformer shaft 22. In this embodiment, after the steel wire passes through the deformer shaft 22 and is deformed, it will be collected by the wire gathering assembly 3, which is located on the same side of the support plate 1 and the guide wheel 4. It should be noted that in order to ensure that the tension of the steel wire after pre-deformation of the deformer assembly 2 remains consistent, the distance from each deformer shaft 22 to the point where the steel wires converge in the wire gathering assembly 3 is the same.
[0027] In use, the steel wire, after being redirected by the guide wheel 4, passes between the deformer shaft 22 and the assembly slot 211, thus entering the deformer shaft 22. After pre-deformation by the deformer shaft 22, it converges into the wire-gathering assembly 3. During this process, the steel wire exerts radial pressure on the deformer shaft 22, which is evenly distributed on the first bearing 222 and the second bearing 223 located on both sides of the deformer shaft 22. Compared to the traditional cantilever structure deformer shaft 22, the radial force borne by each bearing in this design is only half that in the traditional cantilever structure, thus significantly extending the service life of the bearings. Furthermore, in this design, the steel wire is always located between the deformer shaft 22 and the assembly slot 211, effectively avoiding the risk of detachment from the deformer due to loosening or jumping, thereby further improving the reliability and safety of the entire deformation process.
[0028] Example 2:
[0029] Based on the same inventive concept as Embodiment 1, refer to Figure 1 In this embodiment, the double-sided bearing deformer of the internal wire twisting machine includes: a support plate 1 and multiple deformation components 2 circumferentially and equidistantly arranged on the side of the support plate 1. The support plate 1 serves as the basic support structure, ensuring the stability and accuracy of the deformation components 2. The multiple deformation components 2 are circumferentially and equidistantly distributed on the support plate 1, ensuring uniform output of multiple steel wires after pre-deformation.
[0030] refer to Figure 2 , Figure 2 This includes a partial semi-perspective view of the deformable component. In this embodiment, the deformable component 2 includes: a deformer frame 21, which is threadedly connected to the support plate 1. The frame 21 has an assembly groove 211 with opposing bearing holes on both sides. A first bearing 222 and a second bearing 223 are respectively installed in the two bearing holes. A deformer shaft 22 is installed within the assembly groove 211, and both ends of the deformer shaft 22 are rotatably connected to the first bearing 222 and the second bearing 223, respectively. In this embodiment, the deformer shaft 22 includes a deformable wheel 221 and rotating shafts protruding from the axial sides of the deformable wheel 221. The rotating shafts at both ends are rotatably connected to the first bearing 222 and the second bearing 223, respectively. The deformable wheel 221 can pre-deform the steel wire. Specifically, a groove is formed around the center of the deformable wheel 221. The groove provides a clear path for the steel wire, allowing it to travel along a predetermined trajectory during deformation. This helps reduce the swaying and offset of the steel wire during deformation, thereby improving the accuracy and consistency of the deformation. It can also ensure that the radial pressure on the first bearing 222 and the second bearing 223 is average, thus extending the service life of the bearings.
[0031] Furthermore, a guide wheel 4 is provided on one side of the deformer shaft 22 to guide the steel wire correctly into the deformer shaft 22. To maximize the use of the space in the inner wire feeding cradle of the wire feeding twister, in this embodiment, the guide wheel 4 is mounted on the deformer frame 21.
[0032] After pre-deformation, the steel wires are collected by a wire-collecting assembly 3 located on the same side of the support plate 1 and the guide wheel 4. In this embodiment, the wire-collecting assembly 3 includes a wire-collecting nozzle frame 31 and a wire-collecting nozzle 32 disposed on the wire-collecting nozzle frame 31. The wire-collecting nozzle 32 is equidistant from the multiple deformation assemblies 2, thereby ensuring that each steel wire enters the wire-collecting nozzle 32 along the same path and angle after passing through the deformation assemblies 2, thus guaranteeing the uniformity and consistency of the steel wires.
[0033] In this embodiment, the deformable component 2 has 6 strands. Due to its structural characteristics, the 6-strand steel wire is suitable for engineering applications requiring high strength and stability.
[0034] This embodiment also includes a base 5 disposed inside the wire feeding cradle of the inner wire feeding twister, for supporting the support plate 1 and the wire gathering assembly 3.
[0035] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
