[0001] The invention relates to the technical field of automobile instrument panel crossbeam processing, in particular to an automobile instrument panel crossbeam processing device. Background Art

[0002] The car dashboard crossbeam is an important part of the car's internal structure. It not only provides installation and support for the dashboard assembly and other system parts (such as the steering column, air conditioning, entertainment system, instrument cluster, front passenger airbag, etc.), but is also directly connected to the car body. It plays a key role in energy absorption and load transfer in vehicle collisions, and is directly related to the safety protection performance of the occupants. At present, the car panel crossbeam is usually made by first clamping various pipes and then welding them.
