Problems solved by technology

[0003] However, after using traditional welding and riveting to connect plates, quenching treatment is generally not performed. This is because if the joints are quenched, firstly, production steps such as heating and cooling of the joints are added, which reduces production efficiency; The material expands with heat and contracts with cold, and quenching will cause more tensile stress at the interface joint of the connection, causing a safety hazard

Abstract

The invention provides an integrated anti-extrusion connecting system and a method thereof for water-knife forming, strengthening and quenching. The system comprises a connecting device, a water-knifepower system, an electric control system and a water circulation treatment system, wherein the connecting device comprises a spray head and a connecting tool; the water-knife power system comprises awater tank, a filter, a low-pressure water pump, a check valve, a high-pressure water pump, an energy accumulator, a throttle valve, a hard particle tank, a mixing cavity and a stop valve, and the stop valve is located above the spray head; the electric control system is electrically connected with the high-pressure water pump, the low-pressure water pump, electromagnetic coils and a blank holderhydraulic system; and one end of the water circulation treatment system is connected with the water tank of the water-knife power system, and the other end of the water circulation treatment system is connected with a water collector. The system is used for connecting multi-layer plates, forming, quenching and strengthening are integrated, the production efficiency is high, the connection reliability is high, and the connection position has the advantages of compact metal structure, high strength, strong wear resistance, high hardness and the like.

Description

Technical field [0001] The invention relates to the field of plate connection, in particular to a water jet forming, strengthening and quenching integrated back-extrusion connection system and a method thereof. Background technique [0002] In recent years, with the gradual rise of new energy vehicles, more and more attention has been paid to "lightweight". Lighter bodies help reduce fuel consumption and reduce CO 2 Emissions, enhance the stability of body control. The core of lightweight is to use a large number of lightweight materials and use lightweight structures as much as possible. Welding and riveting, as two commonly used connection technologies for connecting lightweight panels, are widely used in the connection of white body panels. [0003] However, after using traditional welding and riveting to connect the plates, the quenching treatment is generally not performed. This is because if the quenching treatment is performed on the connectors, one is to increase the produ...
