Automated processing line for bending and forming aluminum alloy crash beams
ActiveCN117840283BImprove yield rateEfficient preheatingMetal-working feeding devicesVehicle componentsHeat resistanceStructural engineering
This invention discloses an automated processing line for bending and forming aluminum alloy crash beams, comprising a feeding device and a bending and forming device. A feeding conveyor belt transports hollow aluminum alloy profiles through an open opening to a profile support in a heating chamber. Each set of heating resistance wires, driven by a corresponding resistance wire drive cylinder, is inserted into the hollow aluminum alloy profile to heat it. The transfer assembly transports the heated hollow aluminum alloy profile to the bending and forming device. The bending and forming device bends the hollow aluminum alloy profile into an aluminum alloy crash beam. The feeding device not only automatically feeds the profile to the bending and forming device but also efficiently preheats the hollow aluminum alloy profile, thereby improving its plasticity, significantly reducing the bending difficulty of the profile, improving processing accuracy, and ultimately greatly increasing the yield rate of the aluminum alloy crash beams.
