A bending device for aluminum alloy anti-collision beams

Abstract

This utility model discloses an aluminum alloy anti-collision beam bending device, specifically relating to the field of anti-collision beam processing technology. It includes a bending base, a bending support frame on the outer side of the upper end of the bending base, and multiple first hydraulic telescopic rods in the middle of the lower end of the bending base. A bottom support block is located at the upper end of the output shaft of each first hydraulic telescopic rod, and multiple second hydraulic telescopic rods are located at the upper end of the bending pressure plate. In actual use, by aligning the rotating slot, limiting block, L-shaped support sleeve, cutting groove, pull rod, limiting protrusion, movable retaining ring, and support spring, when installing or replacing the bottom and top mold slots, the pull rod can be pulled outwards. This causes one end of the pull rod to disengage from the bottom and top mold slots, and the limiting protrusion is rotated and locked inside the rotating slot. This allows the pull rod to retract stably into the limiting block, making the installation and replacement of the bottom and top mold slots more stable and convenient.

Description

Technical Field

[0001] This utility model relates to the field of anti-collision beam processing technology, and more specifically, to an aluminum alloy anti-collision beam bending device. Background Technology

[0002] Traditional crash beams are mostly made of high-strength steel, but with increasingly higher requirements for the structural strength of crash beams and the design requirements for lightweight vehicles, crash beams made of aluminum alloy are becoming more and more common. The production of aluminum alloy crash beams requires first extruding hollow aluminum alloy profiles, then stamping these profiles into aluminum alloy crash beams, and finally processing them using bending equipment. For example, patent CN221289127U discloses a dot-matrix aluminum alloy anti-collision beam bending device. A guide support plate extending upwards is vertically installed on one side of the gantry frame's bottom beam in the width direction. The guide support plate has strip-shaped guide grooves corresponding to the screw mounting holes of each support block. Each strip-shaped guide groove extends vertically, and the shaped support blocks are fitted against the guide support plate. Each shaped support block slides with its corresponding strip-shaped guide groove via a sliding fit component. By setting the guide support plate, the shaped support blocks can be limited and guided.

[0003] When the above-mentioned device is used, its investment cost is far lower than that of replacing the entire device, and it is simple and convenient to operate. Due to the flexibility of the support block matrix module, it can be used for bending and forming anti-collision beams with a lot of bending changes. However, the lower die of the anti-collision beam bending is prone to displacement during operation. At the same time, when the anti-collision beam is bent, it is easy for the anti-collision beam to shift, resulting in uneven bending on both sides of the anti-collision beam. Utility Model Content
