The present invention is not limited to the above-described embodiments, and technical ideas that can be modified and converted by those skilled in the art to which the present invention pertains without departing from the gist of the present invention also belong to the following claims. Should be seen.

According to the present invention of the above configuration, the present invention is configured to be used to connect and use as needed through a separate connecting device without configuring the hydraulic pump for driving the busbar processing apparatus inside the apparatus busbar processing apparatus Its size and weight are reduced, making it portable.

In addition, the present invention portable busbar processing apparatus is reduced in size and weight is configured to be very convenient to transport and installation can be easily processed and molded as needed in any place, there is an effect of reducing the work efficiency and time. .

In addition, the present invention is the processing means for performing the processing and molding, such as bending, cutting, punching, terminal crimping, the size of the apparatus main body by allowing the upper tool fixture installed in the processing apparatus can be replaced and used as necessary, While reducing, it is possible to configure a variety of machining operations with a single upper tool fixing to increase the work efficiency.

In addition, the present invention can be used in a variety of forms and sizes of the processing means for performing the punching and terminal crimping process to replace the processing means suitable for the distribution board to be configured, such as processing and molding of various shapes and sizes have.

In addition, the present invention has the effect that the bending process is made even if the length is long or multiple bending is required by allowing the processing device to rotate by 90 ° if necessary.
