Description

Technical Field

[0001] This utility model belongs to the field of copper busbar bending technology, specifically relating to an angle-controlled splitter and a copper busbar bending mold. Background Technology

[0002] Copper busbars are essential components for transmitting current and connecting electrical equipment. They not only have efficient current conduction capabilities but also excellent heat dissipation and corrosion resistance. In electrical construction where on-site fabrication or assembly is required, the length and bending angle of the copper busbars need to be determined based on the actual site conditions. Currently available portable copper busbar bending machines mark the angle information on the base, relying on visual judgment during bending. While this method doesn't introduce significant errors and has minimal impact on construction under favorable conditions, it becomes problematic in challenging environments. Poor visual perception and limited visibility significantly increase prefabrication errors during bending. The original equipment required a high-quality prefabrication environment, necessitating an open, flat, and well-lit location. Operators could only visually confirm the prefabrication's accuracy using the base markings as a reference. However, varying operator positions and visual perception can lead to over-bending or under-bending, increasing the risk of secondary bending damage to the copper busbar and increasing material waste. Furthermore, it demanded high manpower, requiring two or more operators working together. In addition, irregularly bent copper busbars can lead to increased resistance, localized overheating, reduced equipment efficiency, and increased risk of equipment failure. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an angle-controlled splitting head and copper busbar bending mold to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] An angle-controlled splitter is provided, comprising a vertically fixed rotating shaft, a screw, a rotating nut, a fixing block, and two angle control plates. The fixing block has a transverse through hole. The two angle control plates are adjacent to each other at the location of the vertically fixed rotating shaft, and both angle control plates can rotate around the vertically fixed rotating shaft. One end of the screw passes through the transverse through hole and connects to the vertical middle area of ​​both angle control plates.

[0025] The terms “utility model” and “this utility model” used in this specification are intended to broadly refer to all subject matter of this specification and any of the following patent claims. Statements containing these terms should not be construed as limiting the subject matter described herein or limiting the meaning or scope of any of the following patent claims. Furthermore, this specification does not attempt to describe or limit the subject matter covered by any claim of any particular component, paragraph, statement, or drawing of this application. The subject matter should be understood with reference to the entire specification, all drawings, and any of the following claims. This utility model may have other embodiments and be practiced or implemented in other ways. Moreover, it should be understood that the wording and terminology used herein are for illustrative purposes and should not be considered limiting.

[0026] The details of the present invention will now be discussed with reference to the accompanying drawings, which are illustrated by way of example only. In the drawings, similar features or components may be labeled with the same reference numerals.

[0027] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein, their equivalents, and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0028] See Figures 1 to 3 As shown in the preferred embodiment, the angle control wedge of this utility model includes a vertical fixed rotating shaft, a screw 1, a rotating nut 2, a fixing block 3, and two angle control plates 4. The fixing block 3 has a transverse through hole. The two angle control plates 4 are adjacent to each other at the location of the vertical fixed rotating shaft, and both angle control plates 4 can rotate around the vertical fixed rotating shaft. One end of the screw 1 passes through the transverse through hole and connects to the vertical middle area of ​​the two angle control plates 4. The rotating nut 2 is fitted onto the other end of the screw 1 at the joint with the fixing block 3.

[0029] Furthermore, this split head also includes a hinge 5, through which two angle control plates 4 are fixedly connected to each other. It can be understood that the hinge 5 forms a vertically fixed rotation axis.

[0030] The end of the screw 1 is provided with a connector 6. The screw 1 is connected to the angle control plate 4 through the connector. The connector 6 is in the shape of an angle steel and the length of the connector 6 is at least 2 / 3 of the vertical length of the angle control plate 4.

[0031] The angle between the two angle control plates 4 is between 0° and 90°. In other words, the bending angle of the two angle control plates 4 can be adjusted arbitrarily within the range of 0° to 90°.

[0032] See Figure 4 As shown, this utility model also provides a copper busbar bending mold, which includes a base 7 and an angle control wedge as described above located on the base 7.

[0033] Once the required angle of the copper busbar is measured on-site, the screw 1 can be moved back and forth by rotating the rotating nut 2, thereby driving the connector 6 to push the two angle control plates 4 connected by the hinge 5 to merge to the required angle position. Then, the copper busbar is put into the bending mold, and the hydraulic pusher is started to bend the copper busbar. When the copper busbar is completely in contact with the angle control plates 4 on both sides, it means that the required bending angle has been reached. The hydraulic pusher is turned off, and the copper busbar is taken out, thus completing the copper busbar bending.

[0034] This angle-controlling splitter and related copper busbar bending mold can not only accurately bend to the required angle, but also avoid irregularities and the possibility of secondary processing during the bending process. Compared with existing molds on the market, it can complete the prefabrication with minimal error under any circumstances, thereby reducing material waste and various failure risks during later operation. It is suitable for construction that requires on-site processing of copper and aluminum busbars, such as outdoor or cabinet and switch assembly with limited operating space.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
