Description

Technical Field

[0001] This invention relates to the field of current bar processing, specifically a current bar processing and forming apparatus. Background Technology

[0002] As a core component in electrical equipment used for conducting current, the quality of its processing and forming directly affects the operational stability and safety of the equipment. Therefore, the precision and efficiency of basic processing steps such as rolling and conveying are crucial in the production of current bars. Currently, existing current bar processing and forming equipment still has many shortcomings in practical applications, making it difficult to meet the processing needs of current bars of different specifications, thus limiting the improvement of production efficiency and product qualification rate.

[0003] Existing current strip rolling processes mostly employ single, fixed pressure roller devices. The fixed roller positions prevent flexible adjustment based on the varying thickness of the current strip raw material. This leads to problems such as incomplete rolling, wrinkles on the raw material surface, or excessive rolling pressure damaging the material when rolling thicker or thinner materials, thus affecting subsequent processing steps. Furthermore, the conveyor belts used in existing devices are typically set at a fixed height, preventing the precise and stable transport of the rolled raw material onto the conveyor belt.

[0004] Furthermore, existing adjustable-height conveyor devices have complex adjustment structures, are cumbersome to operate, and have low adjustment accuracy. They cannot quickly and accurately adjust the height of the conveyor belt end according to the thickness requirements of the current strip processing, resulting in poor adaptability. For current strip raw materials of different thicknesses, it is often necessary to replace different processing components or adjust the layout of the entire device, which is inconvenient, time-consuming, and labor-intensive. This greatly reduces the versatility and practicality of the processing and forming device, increases production input costs, and makes it difficult to meet the needs of large-scale and diversified production.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention 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 the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please refer to the attached drawings. An electrical strip processing and forming device includes a base 1. In the core mounting area of ​​the base 1, two symmetrically arranged first supports 2 are fixedly connected. These two first supports 2 serve as mounting carriers for the pressure roller assembly. Two pressure rollers 3 for pressing and forming electrical strips are symmetrically arranged between them, forming the core forming structure of the device.

[0033] To enable height adjustment of the upper pressure roller 3 to accommodate the processing requirements of current strips of different thicknesses, a telescopic mechanism 4 is fixedly connected to the top of the first support 2. The telescopic end of the telescopic mechanism 4 is fixedly connected to the first bearing 5, while the upper pressure roller 3 is rotatably connected to the first bearing 5. The height of the upper pressure roller 3 can be flexibly adjusted by the telescopic movement of the telescopic mechanism 4. Simultaneously, to facilitate bidirectional adjustment of the upper pressure roller 3, a height adjustment component 6 is also provided on the top of the base 1. This component is mainly used to adjust the height of the lower pressure roller 3. Its specific structure includes a second bearing 7 that is longitudinally slidably connected to the first support 2. The lower pressure roller 3 is rotatably connected to the second bearing 7. By sliding the second bearing 7 longitudinally on the first support 2, the height of the lower pressure roller 3 can be adjusted.

[0034] Specifically, the transmission structure of the height adjustment component 6 is as follows: it includes a third shaft seat 10 fixedly connected to the base 1, a screw 11 rotatably connected above the third shaft seat 10 as the core of the power transmission for height adjustment, a transmission sleeve 12 threadedly connected to the end of the screw 11, and an inclined rod 13 rotatably connected to the outside of the transmission sleeve 12; correspondingly, a sliding shaft 14 rotatably connected below the second shaft seat 7, a drive sleeve 15 rotatably connected to the end of the sliding shaft 14, and the other end of the inclined rod 13 rotatably connected to the drive sleeve 15. When the screw 11 rotates, it drives the transmission sleeve 12 to move along the axial direction of the screw 11, which in turn pushes the drive sleeve 15 and the sliding shaft 14 to move through the inclined rod 13, ultimately driving the second shaft seat 7 and the lower pressure roller 3 to complete the height adjustment.

[0035] To adjust the rotation of the screw 11, a drive block can be fixedly installed in the middle of the screw 11, facilitating the rotation of the screw 11 using the drive block. The operation of flattening the current strip material using the pressure roller 3 is common knowledge in the field, and the supporting mechanism will not be described in detail. For example, one pressure roller 3 can be driven by a motor to rotate, working in conjunction with the other pressure roller 3 to achieve flattening.

[0036] To further enhance the synchronicity and stability of height adjustment, the screw 11 adopts a bidirectional screw design with symmetrically distributed threads on its outer side. Two corresponding transmission sleeves 12 are also provided, symmetrically distributed on the outer side of the screw 11. Each transmission sleeve 12 is connected to a tilting rod 13 and a drive sleeve 15, with the two drive sleeves 15 respectively connected to both ends of the sliding shaft 14. This symmetrical structure ensures that when the screw 11 rotates, the two transmission sleeves 12 move synchronously in opposite directions, thereby driving the sliding shaft 14 to be simultaneously stressed through the tilting rod 13, preventing the second shaft seat 7 from tilting and ensuring the levelness of the lower pressure roller 3 during adjustment.

[0037] In addition to the core forming pressure roller assembly, the device is also equipped with a conveying assembly 8 for conveying the current strip raw material. The conveying assembly 8 is fixedly connected to the base 1, and its core component is the conveyor belt 9. The conveying end of the conveyor belt 9 is precisely aligned with the sides of the two pressure rollers 3, which can smoothly convey the current strip that has completed the flattening process to the next process, thus achieving the continuity of the forming process.

[0038] The conveying assembly 8 consists of a first conveying roller 16, a second conveying roller 17, and a conveyor belt 9. The conveyor belt 9 is sleeved on the outside of the first conveying roller 16 and the second conveying roller 17. The rotation of the two conveying rollers drives the conveyor belt 9 to move, thereby realizing the conveying of the current strip. The first conveying roller 16 is connected to the first bracket 2. To facilitate the adjustment of the distance between the conveyor belt 9 and the pressure roller 3, a limiting groove 18 is slidably connected on the first bracket 2. A first roller shaft 19 is rotatably connected to the axial position of the first conveying roller 16. The first roller shaft 19 is slidably engaged with the limiting groove 18 and can slide up and down along the limiting groove 18 to adjust the position of the first conveying roller 16. To fix the adjusted position, locking nuts 20 are threaded to both ends of the first roller shaft 19. When the locking nuts 20 are locked, the first roller shaft 19 is fixed and cannot slide in the limiting groove 18, thereby ensuring the stability of the position of the conveyor belt 9.

[0039] The second conveyor roller 17 serves as the power output end of the conveying assembly 8. A second roller shaft 21 is fixedly connected to its axial center. The second roller shaft 21 is rotatably connected to the second support 22, which in turn is rotatably connected to the base 1. The second support 22 can rotate around its connection point with the base 1, thereby adjusting the position of the second conveyor roller 17. To provide rotational power to the second conveyor roller 17, a first motor 23 is fixedly connected to the second support 22. The first motor 23 is connected to the second roller shaft 21 via a gear set 24. The operation of the first motor 23 transmits power through the gear set 24, driving the second roller shaft 21 and the second conveyor roller 17 to rotate, thus driving the conveyor belt 9 to operate normally.

[0040] To achieve flexible adjustment and fixation of the second support 22, the second support 22 adopts a telescopic and adjustable structure, which includes a limiting sleeve 25, which is rotatably connected to the base 1. An adjusting inner rod 26 is slidably connected inside the limiting sleeve 25, and a locking bolt 27 is threadedly connected to the side of the limiting sleeve 25. By tightening the locking bolt 27, the position of the adjusting inner rod 26 inside the limiting sleeve 25 can be locked, thereby adjusting the overall height of the second support 22. At the same time, an electric telescopic rod 28 is rotatably connected to the base 1. A sleeve 29 is fixedly connected to the telescopic end of the electric telescopic rod 28. A driven rod 30 is fixedly connected to the limiting sleeve 25. The sleeve 29 is rotatably connected to the driven rod 30. When the electric telescopic rod 28 extends or retracts, it pushes the driven rod 30 through the sleeve 29, thereby causing the limiting sleeve 25 to rotate around the connection position with the base 1, thereby realizing the angle adjustment of the second conveying roller 17. In addition, a U-shaped frame 31 is fixedly connected to the top of the adjusting inner rod 26. Both the first motor 23 and the second roller shaft 21 are connected to the U-shaped frame 31 to ensure the stability of power transmission. It should be noted that during the extension and retraction adjustment of the electric telescopic rod 28, it needs to be coordinated with the position of the first roller shaft 19 to ensure that the conveyor belt 9 is in a taut state. To avoid this problem, a tensioning mechanism can be set up to achieve the tensioning operation of the conveyor belt 9.

[0041] In addition, a third support 32 is provided on the base 1. The third support 32 is fixedly connected to the base 1. A longitudinal groove 33 is opened on its surface. A longitudinal slide rod 34 is slidably connected inside the longitudinal groove 33. A guide rod 35 is fixedly connected above the longitudinal slide rod 34. A spring 36 is fixedly connected to the outside of the guide rod 35. Under the elastic force of the spring 36, the longitudinal slide rod 34 always tends to move towards the conveyor belt 9. A stop block is fixedly connected to the longitudinal slide rod 34. When the longitudinal slide rod 34 moves downward, the stop block will block the current strip material, thereby preventing the current strip from continuing to be conveyed and avoiding material accumulation or misalignment during processing. In order to control the opening and closing of the stop block, a limiting unit 37 for driving the longitudinal slide rod 34 to move upward is also provided on the third support 32.

[0042] The limiting unit 37 serves as the control core for the opening and closing of the stop. Its specific structure includes a second motor 38 fixedly connected to the third bracket 32, a positioning shaft 39 rotatably connected to the middle of the third bracket 32, and the positioning shaft 39 and the second motor 38 connected through a transmission structure, with the second motor 38 driving the positioning shaft 39 to rotate. Cams 40 are fixedly connected to both ends of the positioning shaft 39, and a push rod 41 is fixedly connected below the longitudinal slide rod 34. The lower end of the push rod 41 abuts against the cam 40. When the positioning shaft 39 drives the cam 40 to rotate, the protruding end of the cam 40 pushes the push rod 41 to move upward, thereby driving the longitudinal slide rod 34 to slide upward, causing the stop to disengage from the conveyor belt 9 and allowing the current strip to be conveyed. When the flat end of the cam 40 abuts against the push rod 41, the longitudinal slide rod 34 slides downward under the elastic force of the spring 36, and the stop blocks the current strip, thus achieving the conveying limit.

[0043] To ensure smooth and stable transmission, a driven pulley 42 is fixedly connected to the outer side of the positioning shaft 39, and a driving pulley 43 is fixedly connected to the output shaft of the second motor 38. A transmission belt 44 is sleeved between the driving pulley 43 and the driven pulley 42, and the power transmission between the second motor 38 and the positioning shaft 39 is realized through the transmission belt 44. At the same time, a roller 45 is fixedly connected to the bottom of the push rod 41. The roller 45 abuts against the outer edge of the cam 40, converting sliding friction into rolling friction, reducing wear between the push rod 41 and the cam 40, and improving the service life and operational stability of the limit unit 37.

[0044] In addition, two conveying components 8 can be provided in this application, located on both sides of the pressure roller 3 respectively. One side is used to convey raw materials inward, and the other side is used to output the flattened raw materials outward. The matching third bracket 32, limiting unit 37 and associated connecting mechanism can be symmetrically arranged on both sides, which makes the processing of the current strip more convenient and significantly improves production efficiency.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
