Description

Technical Field

[0001] This utility model relates to the field of metal profile processing technology, and in particular to a bending machine for coiling. Background Technology

[0002] Bending is a common process in the processing of metal profiles such as copper and aluminum busbars. In existing technologies, vertical bending machines are prone to interference between equipment components and the workpiece when performing large-angle bends, leading to obstructed bending operations or workpiece damage. Sheet metal bending machines, on the other hand, suffer from insufficient positioning accuracy, making it difficult to guarantee the accuracy of the bending position and affecting product quality. Furthermore, the inconvenience of replacing the actuators in traditional bending equipment reduces production efficiency and fails to meet diverse processing needs. Therefore, it is necessary to design a new type of coil bending machine to solve these problems. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the present invention aims to provide a bending machine for coiling, which solves the problems of large bending angle interference, low positioning accuracy and inconvenient replacement of the actuator in existing equipment.

[0004] To achieve the above and other related objectives, the technical solution provided by this utility model is: a bending machine for bending copper busbars and aluminum busbars, comprising:

[0005] frame;

[0006] A fixture base, which is fixed on the frame, is used to position the product;

[0007] A bending assembly includes a rotating shaft, a positioning bushing, and a bending component. The rotating shaft is rotatably mounted on the frame. The positioning bushing is rotatably mounted on the end of the rotating shaft and located on the top side of the product, used to determine the bending part of the product. The bending component is fixed on the rotating shaft and located on the bottom side of the product, used to bend the product to a set angle.

[0008] A drive assembly, which is fixed on the frame, is used to drive the rotating shaft to rotate.

[0009] A preferred technical solution is as follows: a chassis is fixedly mounted on the top of the frame, and two sets of bearing seats are provided on the top side of the chassis, which are spaced apart and opposite to each other. The rotating shaft is rotatably mounted in the bearing seats through bearings.

[0010] A preferred technical solution is that a coaxially arranged shaft is fixed at the end of the rotating shaft, and the positioning sleeve is sleeved on the shaft.

[0011] The preferred technical solution is that the positioning bushing is made of brass.

[0012] The preferred technical solution is as follows: the drive assembly consists of a servo motor, a reducer, a coupling, a drive shaft, a drive gear, and a driven gear; the drive shaft is rotatably mounted inside the housing via bearings and is arranged parallel to the rotating shaft; the drive gear is fixed on the rotating shaft, the driven gear is fixed on the rotating shaft, and the drive gear and the driven gear are meshed; the output end of the servo motor is drivenly connected to the input end of the reducer, the output end of the reducer is drivenly connected to the input end of the coupling, and the output end of the coupling is drivenly connected to the drive shaft.

[0013] The preferred technical solution is as follows: the reducer is fixed to the housing of the chassis by a fixed frame, and the coupling is located in the fixed frame.

[0014] The preferred technical solution is as follows: the fixture base is provided with a positioning groove for positioning the product; the fixture base is also provided with a quick clamp for clamping the product in the positioning groove.

[0015] The preferred technical solution is that the bent part is provided with multiple sets of positioning pins on the side close to the product for positioning the product.

[0017] Controllable bending angle: Through the precise transmission of the servo motor, reducer and gear set, the rotation angle of the shaft can be precisely controlled, thereby achieving precise control of the bending angle of copper busbars and aluminum busbars to meet different processing requirements.

[0018] To avoid interference at large bends: The bending assembly adopts a structural design with the positioning bushing located on the top side of the product and the bending part located on the bottom side of the product. With a reasonable spatial layout, it effectively compensates for the interference problem of the vertical bending machine when bending at large bends, ensuring that the bending process proceeds smoothly.

[0019] Precise and reliable positioning: The positioning groove of the fixture seat achieves initial positioning of the product, and the quick clamp firmly clamps the product; the positioning pin of the bending part further positions the product, while the positioning bushing assists in determining the bending part. The multi-positioning structure solves the shortcoming of insufficient positioning accuracy of sheet metal machines and ensures the accuracy of the bending position.

[0020] Easy and efficient operation: The quick-clamp design of the fixture seat facilitates quick clamping of products. The fixture seat can be quickly removed and replaced, which can adapt to the processing needs of products of different specifications, shorten the changeover and adjustment time, and improve production efficiency.
