Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, and in particular to a straightening machine for copper busbars. Background Technology

[0002] A copper busbar straightening machine is a specialized device used to straighten bent or deformed copper busbars (also known as copper busbars). Copper busbars are prone to bending, twisting, or wavy deformation during transportation, handling, or storage, which directly affects their installation accuracy, contact performance, and electrical safety in electrical cabinets, switchgear, transformers, and other applications. The function of the straightening machine is to restore the straightness of the copper busbars and ensure that they meet assembly requirements.

[0003] However, in the existing technology, traditional copper busbar straightening machines are not convenient for limiting the width of the copper busbar. Therefore, when passing through multiple straightening rollers and drive rollers, the copper busbar is prone to sliding left and right on its surface, which affects the straightening effect and may even damage the straightening machine. Moreover, the surface of the copper busbar is not cleaned before straightening, and the dust particles attached to the surface can easily scratch the surface of the copper busbar during the straightening process, thereby reducing the quality of the copper busbar. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where traditional copper busbar straightening machines are not convenient for limiting the width of the copper busbar. Therefore, when passing through multiple straightening rollers and transmission rollers, the copper busbar is prone to sliding left and right on its surface, which affects the straightening effect and may even damage the straightening machine. In addition, the surface of the copper busbar is not cleaned before straightening, and the dust particles attached to the surface can easily scratch the surface of the copper busbar during the straightening process, thereby reducing the quality of the copper busbar.

[0019] The technical effect of adopting the above-mentioned further solution is that the telescopic sleeve extends and retracts with the movement of the moving plate, thus providing better protection for the bidirectional lead screw.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the servo motor is turned on to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the moving plate to adjust multiple baffles.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1-4 As shown, this utility model provides a straightening machine for copper busbars, including: a base plate 1, a positioning component, and a cleaning component; The positioning component includes: a through groove 101 is provided at the center of the base plate 1, a transmission roller 113 is movably embedded in one side of the through groove 101, a stepper motor 103 is fixedly installed on one side of the base plate 1, and the output end of the stepper motor 103 is connected to the transmission roller 113. Multiple driven rollers 102 are movably embedded inside the through groove 101; Among them, the stepper motor 103 can drive the transmission roller 113 to rotate, and drive the copper busbar that needs to be straightened. Multiple driven rollers 102 facilitate the movement of the copper busbar, so that it can pass through multiple straightening rollers 118 for repeated bending and reverse bending, gradually eliminating internal stress and restoring it to straightness. A bidirectional lead screw 114 is movably embedded in the center of the lower end of the through groove 101. A guide rod 120 is fixedly installed inside the bidirectional lead screw 114. A movable plate 115 is movably sleeved on the outer surface of the guide rod 120 and the bidirectional lead screw 114. Multiple baffles 116 are fixedly installed on the top of the movable plate 115. Multiple baffles 116 are interspersed between multiple driven rollers 102 and transmission rollers 113. When the servo motor 119 is turned on, it drives the bidirectional lead screw 114 to rotate. The bidirectional lead screw 114 drives the multiple baffles 116 to move relative to each other or in opposite directions through the moving plate 115. The adjustment is made according to the width of the copper busbar. The baffles 116 limit the copper busbar to prevent it from swaying left and right during the straightening process, which would affect the straightening effect. The baffles 116 are interspersed in the gaps between the multiple driven rollers 102 and do not contact the driven rollers 102, so they will not affect the rotation of the driven rollers 102. In addition, a telescopic sleeve 117 is movably fitted on the outer surface of the bidirectional lead screw 114. The telescopic sleeve 117 is fixedly installed on the outer surface of the movable plate 115 and extends and retracts as the movable plate 115 moves, thus better protecting the bidirectional lead screw 114.

[0027] In this embodiment, a mounting bracket 104 is fixedly installed on the top of the base plate 1 near the through groove 101. A hydraulic cylinder 105 is fixedly installed at the top center of the mounting bracket 104. The output end of the hydraulic cylinder 105 passes through the mounting bracket 104. A U-shaped plate 106 is fixedly installed on the output end of the hydraulic cylinder 105. Multiple straightening rollers 118 are movably embedded inside the U-shaped plate 106. The hydraulic cylinder 105 drives the multiple straightening rollers 118 to adjust up and down according to the thickness of the copper busbar through the U-shaped plate 106. The multiple straightening rollers 118 are intersected with the transmission roller 113 and the multiple driven rollers 102. The baffle plate 116 is also inserted in the gap of the straightening rollers 118, so it will not affect the straightening operation of the straightening rollers 118.

[0028] Example 2, as Figure 1-4 As shown, the cleaning assembly includes: a U-shaped frame 109 fixedly installed on one side of the top outer surface of the base plate 1; a movable rod 108 is movably embedded at the top center of the U-shaped frame 109; a Z-shaped plate 107 is fixedly installed on the top of the movable rod 108; and the other side of the Z-shaped plate 107 is connected to the U-shaped plate 106. Cleaning brush plates 112 are fixedly installed at the lower ends of the movable rod 108 and the U-shaped frame 109 respectively; When the hydraulic cylinder 105 drives the U-shaped plate 106 to move up and down, the Z-shaped plate 107 connected to it drives the moving rod 108 to adjust up and down on the U-shaped frame 109. The moving rod 108 drives the cleaning brush 112 to adjust according to the thickness of the copper busbar, so that the two cleaning brushes 112 can better contact the copper busbar and clean the dust and impurities on its outer surface.

[0029] In this embodiment, the inner opposing surfaces of the U-shaped frame 109 are provided with limiting grooves 110. Limiting blocks 111 are fixedly installed on both sides of one of the cleaning brush plates 112, and the limiting blocks 111 are movably embedded in the limiting grooves 110. The limiting blocks 111 are fixedly installed on both sides of the cleaning brush plate 112 at the bottom of the moving rod 108. When the moving rod 108 moves the cleaning brush plate 112 up and down, the limiting blocks 111 also slide inside the limiting grooves 110. The limiting blocks 111 can improve the stability of the cleaning brush plate 112, so that it can better contact the copper busbar and clean it.

[0030] Working principle: The servo motor 119 is turned on to drive the bidirectional lead screw 114 to rotate. The bidirectional lead screw 114 drives the moving plate 115 to adjust multiple baffles 116. The gap between the two sets of baffles 116 is adjusted according to the width of the copper busbar, so that the copper busbar is more stable on the drive roller 113 and the driven roller 102. Then, the hydraulic cylinder 105 is started to drive multiple straightening rollers 118 to move down through the U-shaped plate 106. The adjustment is made according to the thickness of the copper busbar. The copper busbar to be straightened is then conveyed to the driven roller 102 and the straightening roller 118 through the drive roller 113. The copper busbar is repeatedly bent and reverse bent by multiple straightening rollers 118 to gradually eliminate internal stress and then restore it to straightness. When the hydraulic cylinder 105 moves the U-shaped plate 106, the Z-shaped plate 107 connected to the U-shaped plate 106 moves the moving rod 108 up and down. The moving rod 108 is movably embedded inside the U-shaped frame 109, thus providing greater stability. As the moving rod 108 moves up and down, it also moves one of the cleaning brush plates 112 up and down. The distance between the two cleaning brush plates 112 is adjusted according to the thickness of the copper busbar, which better cleans the outer surface of the copper busbar and prevents dust and impurities from scratching the copper busbar during the straightening process, thus affecting the quality of the copper busbar.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
