Description

Technical Field

[0001] The utility model relates to a mould for automobile processing, in particular to a continuous mould for processing a crossbeam in a rear floor of an automobile. Background Art

[0002] The rear floor crossbeam of a car is part of the rear floor assembly of the car, connected between the rear floor longitudinal beams on both sides, and its function is to improve the torsional rigidity of the rear body, thereby improving collision safety. At the same time, it can also serve as a mounting support for other chassis components. The rear floor crossbeam is usually die-cast or extruded aluminum structure to ensure its strength and rigidity. In order to further improve its performance, some car manufacturers will also use reinforcements or other structural designs on the rear floor crossbeam. When processing the rear floor crossbeam machine of the car, a mold is usually used to stamp the steel to process the steel coil into the rear floor crossbeam of the car. The existing mold for processing the rear floor crossbeam of the car, after unwinding the steel coil, due to the stress in the steel coil, it is not convenient to automatically correct it to become flat. In the process of unwinding, it is generally necessary to control the unwinding speed slowly, which is not convenient for fast unwinding. It is necessary to leave enough time for the steel coil to be squeezed and released under the action of the limit roller. The working speed is slow, which is not conducive to improving the efficiency of unwinding the steel coil. Utility Model Content
