Abstract

The invention provides a spiral riveting and locking welding device for explosive impact forming, comprising: an implementing mechanism, a rivet unit, a guiding and blanking mechanism and a controller; the said rivet unit is collectively stored in a rivet box, and the said implementing mechanism can be moved , the implementing mechanism is used to take the rivet unit from the rivet box and place it on the guide crimping mechanism and fire the rivet unit, and the guide crimping mechanism is pre-pressed on the upper plate and the lower plate On the above, the guide edge clamping mechanism is used to press the upper plate and the lower plate on the flat die, and the controller is electrically connected to the implementing mechanism and the guide edge clamping mechanism respectively, and the controller is used to control the The movement of the implementing mechanism and the pressing of the guiding edge-holding mechanism; also provide a spiral riveting welding method for explosive impact forming. The invention has reasonable structural design, high degree of operation automation, can efficiently complete plate connection, has high connection point precision, strong mechanical performance, and has the characteristics of torque resistance.

Description

Technical field[0001]The present invention relates to the field of rivet connections, and in particular, to a spiral riveting welding apparatus and method of exploding impact molding.Background technique[0002]With the successful launch of the national car, side touch, emissions and other enforcement, in order to achieve the strength of the car structure, reduce emissions, adopt advanced high-strength steel (such as DP steel, TRIP steel, high expansion steel) and aluminum The alloy is unable to convelively become the mainstream trend of automotive materials. These two materials can effectively reduce the weight of the body, reduce fuel consumption, and ensure the safety and comfort of the model. SPR Self-riveting as a connection technology that can connect steel aluminum composite sheets, and is favored by the majority of automakers and is adequately used in the design and manufacturing of the body.[0003]Self-riveting is a cold connection technique for connecting two or more metal sh...
