Technical Field

[0001] This utility model belongs to the technical field of busbar processing equipment, and in particular relates to a busbar bending assembly. Background Technology

[0002] In the power and electronics industries, busbars are crucial components for current transmission, and their shape and precision are vital to equipment performance and safety. With technological advancements and industrial development, the processing requirements for busbars are becoming increasingly stringent, particularly the bending process, which has become a critical technical aspect.

[0003] Traditional busbar bending methods mostly employ manual or semi-automatic equipment, which has several shortcomings in the processing. First, manual operation relies on the worker's experience and skills, making it difficult to guarantee bending accuracy and consistency, and it is also labor-intensive and inefficient. Second, while semi-automatic equipment improves production efficiency to some extent, it still has significant limitations in bending angle and force control, making it difficult to meet the requirements for high-precision, complex-shaped busbar bending.

[0004] To address the aforementioned issues, various busbar bending machines have gradually emerged in the market, aiming to improve bending accuracy and efficiency through mechanization and automation. However, these machines still have some shortcomings in practical applications. For example, some machines lack sufficient movement and positioning accuracy, resulting in irregular busbar shapes and inconsistent dimensions after bending; some machines do not have sufficient bending force to handle thicker and harder busbars; and some machines lack sufficient adjustment capabilities to meet the bending requirements of busbars of different specifications and shapes.

[0005] Therefore, the development of a high-efficiency and precise busbar bending assembly has become an urgent need for the industry. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a highly integrated busbar bending assembly. This bending assembly should possess high-precision movement and positioning capabilities to ensure accurate positioning of the busbar during the bending process; simultaneously, it should also possess strong rotational bending capabilities to provide sufficient bending force and achieve precise control of the bending angle. Furthermore, the bending assembly should have flexible insertion and adjustment capabilities to adapt to the bending requirements of busbars of different specifications and shapes; at the same time, a stable support and fit design is also essential to ensure uniform stress on the busbar during the bending process and to avoid deformation or damage.

[0007] This utility model is implemented as follows: a busbar bending assembly includes a movable rotary bending device and a secondary rotary support bending device mounted on a frame. The movable rotary bending device includes a movable frame, with two parallel linear guide rail assemblies arranged below the movable frame along a direction perpendicular to the busbar conveying direction. A power cylinder is mounted on the frame outside the movable frame, and the piston rod of the power cylinder is connected to the movable frame, driving the movable frame to move horizontally along the direction perpendicular to the busbar conveying direction. A first rotary bending servo motor is mounted on the movable frame, and a first reduction gear pair connected to the first rotary bending servo motor is mounted on the movable frame. The first stage gear of the first reduction gear pair is connected to the motor shaft of the first rotary bending servo motor, and the last stage gear of the first reduction gear pair is mounted on a first power output shaft. A busbar bending insert shaft is mounted on the first power output shaft on the side of the secondary rotary support bending device. The busbar bending insert shaft is provided with a busbar slot. A bending bushing is mounted on the power output shaft inside the movable frame, and two busbar bending shafts are mounted on the bending bushing.

[0008] The power cylinder is either a hydraulic cylinder or a pneumatic cylinder.

[0009] More preferably, the auxiliary rotary support bending device includes a fixed frame, and a rotary support disk is installed on the inner side of the fixed frame corresponding to the position of the busbar bending insertion shaft. The rotary support disk has an insertion shaft positioning hole at its center for inserting the busbar bending insertion shaft, and a bending shaft positioning hole is provided on the rotary support disk corresponding to the bending shaft position.

The first gear of the second reduction gear pair is connected to the motor shaft of the second rotary bending servo motor, and the last gear of the second reduction gear pair is installed on the second power output shaft. A rotary support disk is installed on the second power output shaft on the side of the auxiliary rotary support bending device.

This design not only provides sufficient bending force but also achieves precise control of the bending angle. Simultaneously, the addition of a second rotary bending servo motor to the auxiliary rotary support bending device further enhances the driving force and synchronous control capabilities, enabling the device to maintain stable bending performance even when dealing with thicker and harder busbars.

[0014] Furthermore, the bending assembly features flexible insertion and adjustment capabilities.

The two busbar bending shafts mounted on the bending bushing can be adjusted in position and angle as needed, enabling multi-angle and multi-shape bending of the busbars. This design enhances the equipment's versatility and flexibility, meeting the bending requirements of busbars of different specifications and shapes.

[0015] Meanwhile, the stable support and fit design of the bending assembly also greatly enhances its technical performance. The auxiliary rotary support bending device is installed opposite to the moving rotary bending device, providing stable support and fit for the busbar bending. The insertion shaft positioning holes and bending shaft positioning holes on the rotary support plate enable precise positioning of the insertion shaft and bending shaft, further improving the bending accuracy and efficiency.

[0016] Finally, the high degree of automation and intelligent control of the bending assembly is another highlight of its technological achievements. The application of advanced components such as servo motors and reduction gear pairs enables automated and intelligent control of the bending process. This design not only improves processing efficiency and precision but also reduces the labor intensity and safety risks for operators. Attached Figure Description
