Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a busbar bending machine with an automatic mold changing function. Background Art

[0002] Busbars are widely used in high and low voltage switchgear, transformer manufacturing, box-type substations, bus ducts and other industries for the automated processing of copper and aluminum busbars of various specifications. The machine does not require manual intervention during the processing and has the advantages of fast processing speed. Some busbars need to be bent in advance when they are installed in the box and other positions, and some box bodies are prefabricated semi-finished products. In this case, the bent busbars need to be pre-installed before delivery. The existing busbar bending machines have low clamping efficiency when bending tubular busbars with small diameters, resulting in reduced overall operating efficiency. If manual tools are used, the labor cost required is high and the speed is slow. Among them, a busbar bending machine with application number "CN202220243397.7" can realize automatic discharging, automatic bending, and automatic collection of busbars, which increases efficiency and improves operation safety. The bending angle of the mold of the utility model can be set by the mold, and different bending angles can be operated at the same time, and the mold can be replaced according to needs. However, there are still some improvements in the use of the bending machine: due to different types of busbar bending, the mold needs to be replaced. The device does not have a structure for self-replacing the mold, so manual replacement is required, which is time-consuming and labor-intensive, affecting processing efficiency.
