Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy material forming, in particular to a product forming die-casting device. Background Art

[0002] Traditional automobile bodies are sheet metal welded structures, that is, the "stamping + welding" model. First, a whole roll of steel or aluminum plate is continuously stamped into small sheet metal parts using multiple large presses, and then the stamped small sheet metal parts are welded together to form body structural parts. The welded assembly is the body in white. Currently, except for external covering parts, the welding of all other structural parts and components is usually handed over to the spare parts supplier for production, and the vehicle manufacturer is responsible for welding the structural parts / components together with its own external covering parts to form a body in white.

[0003] "Automobile lightweighting" means significantly reducing the vehicle's curb weight while ensuring its strength and safety performance, thereby improving the vehicle's power and range, reducing fuel consumption, reducing exhaust pollution, and even improving the vehicle's operability and safety.

[0004] It is clear that lightweighting is the most effective way to solve the problem of vehicle endurance. Taking new energy vehicles as an example, reducing the weight of the vehicle itself has become a new direction of concern in the car market. For every 100Kg weight reduction of pure new energy vehicles, the range can be increased by 10%-11%, and the battery cost and daily loss cost can be reduced by 20%.

[0005] At present, the main focus is on lightweighting aluminum alloy anti-collision beams, aluminum shock absorber towers, aluminum hoods and other structures of automobile bodies. Aluminum alloy anti-collision beams usually include a hollow beam on the front side and a connector for connecting the hollow beam to the body. The connector and the hollow beam are usually processed separately and then welded. This processing method is inefficient, and the quality of the aluminum alloy anti-collision beam is unstable due to the uneven process of the welding. Utility Model Content
