Description

Technical Field

[0001] The utility model relates to the technical field of busbar processing, in particular to a bending device used for a three-station busbar machine. Background Art

[0002] Busbar refers to the copper or aluminum bar that connects the main switch in the power cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to serve as a conductor. Power supply devices are often inseparable from copper and aluminum busbars. In busbar production, since some busbars need to be routed at different angles in the distribution cabinet, the busbars need to be bent at different angles. The busbar processing machine is mainly used for busbar processing and bending.

[0003] The busbar processing machine currently used has three processing units: shearing, punching and bending. The main function is to process copper and aluminum busbars of different specifications. Only by using the corresponding processing units, it is convenient and quick to perform various processing procedures such as shearing, punching, flat bending, vertical bending, embossing, flattening, twisting and pressing cable joints on copper and aluminum bars. The existing bending machine generally includes a punch and a die. When in use, the part of the busbar that needs to be bent is marked manually, and then the busbar is placed on the side of the die with a groove from one side. When the die moves horizontally toward the punch, the die will push the busbar to move toward the punch and touch the punch. When the busbar is subjected to the interaction force between the die and the punch, the two ends of the busbar will bend toward the punch side. Because the operator needs to support the busbar with his hands when bending the busbar, the two ends of the busbar will apply a large force in the direction of the punch during the bending process. If the operator does not have time to dodge, it is easy to get injured.

[0004] In actual application, although the existing three-station busbar machine has a ruler, its ruler is set above the processing table. At the same time, since the structure of the die to the punch is fixed, when it is necessary to bend small structural parts, not only is it necessary to adjust the ruler back and forth many times, but it is also necessary to use other auxiliary equipment to complete the processing requirements. The existing processing method not only has low processing efficiency, but also has serious material waste. The bent busbar needs to be sheared twice to meet the use requirements. In addition, in addition to processing copper and aluminum busbars, in the process of making electric cabinets, it is sometimes necessary to bend commonly used angle materials. Therefore, in order to meet the use requirements, the existing three-station busbar machine is improved to provide a bending device that meets the actual use needs. It can not only meet the bending needs of copper and aluminum busbars of different lengths, but also facilitate the bending of other angle materials, thereby reducing the equipment purchase cost and improving the processing efficiency.

[0030] like Figure 4As shown, this embodiment is based on the embodiment 1, firstly, to meet the requirements of bending the busbar with a relatively short size, and secondly, to facilitate the movement of the die 24.
