The fixed wheel assembly includes several lower pressure rollers arranged sequentially, all of which are rotatably mounted on the frame. The movable wheel assembly is located above the fixed wheel assembly, forming a pressure channel between them. The movable wheel assembly includes several upper pressure rollers arranged sequentially, each rotatably mounted on a lifting plate. The lifting plate is mounted on the frame via a vertical slide rail and is driven to move along the vertical slide rail by a lifting drive mechanism.

Description

Technical Field

[0001] This utility model belongs to the field of line straightening technology, specifically relating to line straightening mechanisms. Background Technology

[0002] In wire processing, ensuring high-precision straightness is crucial for product quality. Most existing wire straightening equipment uses a fixed-gap straightening wheel structure, making it difficult to flexibly adjust according to the wire's diameter, material, and degree of curvature. This fixed structure leads to uneven straightening force during the straightening process. For wires with high hardness or severe curvature, effective straightening is impossible; while for softer or thinner wires, excessive straightening force may cause surface damage, severely impacting product yield and production efficiency. Furthermore, while some equipment has adjustable straightening wheel spacing, the adjustment relies on manual operation, lacking precise quantitative control methods. This makes it difficult to guarantee consistent straightening accuracy, and the operation is cumbersome, consuming significant time and labor costs. Utility Model Content

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-3 As shown, the wire straightening mechanism includes a frame 1, a fixed wheel group, and a movable wheel group. The fixed wheel group includes several lower pressing wheels 2 arranged sequentially, all of which are rotatably mounted on the frame 1. The movable wheel group is located above the fixed wheel group, forming a pressing channel between the fixed and movable wheel groups. The movable wheel group includes several upper pressing wheels 3 arranged sequentially, each of which is rotatably mounted on a lifting plate 4. The lifting plate 4 is mounted on the frame 1 via a vertical slide rail 5 and is driven to move along the vertical slide rail 5 by a lifting drive mechanism. The upper pressing wheels 3 are mounted on the lifting plate 4 and are driven to move along the vertical slide rail 5 by a cylinder 6, forming a variable-gap pressing channel with the lower pressing wheels 2. When the wire 15 passes through the pressing channel, the upper and lower pressing wheels 2 apply pressure, eliminating the original bending deformation through repeated bending.

[0018] Furthermore, the lifting drive mechanism includes a cylinder 6 and a translation plate 7. The cylinder 6 is mounted on the frame 1, and the output shaft of the cylinder 6 is fixedly connected to the translation plate 7. The lifting plate 4 is provided with an inclined slide groove 8, and a pulley 9 is provided in the slide groove 8. The pulley 9 is rotatably connected to the translation plate 7. The translation plate 7 is slidably mounted on the horizontal slide rail 16. The cylinder 6 drives the translation plate 7 to translate horizontally. By utilizing the cooperation of the pulley 9 and the inclined slide groove 8, the pulley 9 generates a vertical moving thrust, controlling the vertical movement of the lifting plate 4 to achieve lifting. The pressure of the movable wheel assembly on the wire 15 is adjusted. Compared with directly using the cylinder 6 to drive the lifting plate 4, the inclined slide groove 8 mechanism can reduce the stroke requirement of the cylinder 6, reduce the equipment height, and make the structure more compact.

[0019] Furthermore, vertical slide rails 5 are provided on both sides of the lifting plate 4, and sliders 10 are installed on the vertical slide rails 5. The sliders 10 are fixedly connected to the frame 1. The cooperation between the vertical slide rails 5 and the sliders 10 makes the up-and-down movement of the lifting plate 4 smoother.

[0020] Furthermore, the lower pressure roller 2 and the upper pressure roller 3 are rotatably mounted on the vertical slider 11. The frame 1 and the lifting plate 4 are each provided with several movable openings 12 for the vertical slider 11 to move up and down. Adjustment tracks that cooperate with the vertical slider 11 are installed at the movable openings 12. A nut is fixedly installed on the vertical slider 11, and the nut is threadedly connected to an adjusting screw, which is rotatably mounted on the frame 1. When the adjusting screw is rotated, the nut threadedly engages with it, causing the slider 10 to move up and down along the adjusting track, changing the height of a single pressure roller. By adjusting the height difference between adjacent pressure rollers, the degree of bending of the wire can be controlled to adapt to different bending shapes. For wires 15 with different degrees of bending in different sections, the height of the pressure rollers at the corresponding positions can be adjusted individually to achieve "segmented straightening" and improve the straightening pass rate.

[0021] Furthermore, several micrometers 13 are mounted on the frame 1, each corresponding to a vertical slider 11. The measuring rod of the micrometer 13 is vertically positioned and points towards the corresponding vertical slider 11. The micrometer screw of the micrometer 13 is in rigid contact with the vertical slider 11, and the position change of the slider 10 can be accurately read by rotating the knob. This transforms the traditional "experience-based adjustment" into "data-driven adjustment," allowing operators to directly set the micrometer 13 reading according to the specifications of the wire 15, reducing adjustment time.

[0022] Furthermore, the lower pressure roller 2 and the upper pressure roller 3 are arranged alternately. When the wire 15 passes through the alternate pressure rollers, it is subjected to alternating bending forces in both directions, which forces the internal stress to redistribute and eliminates the original bending deformation.

[0023] Furthermore, guide rings 14 are provided at both ends of the wire pressing channel, and the guide rings 14 are fixedly connected to the frame 1. The wire 15 passes through the guide ring 14 on one side of the frame 1, enters the wire pressing channel, and then passes through the guide ring 14 on the other side.

[0024] It is worth mentioning that the technical features such as cylinders and micrometers involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0025] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
