Abstract

The invention discloses a lightweight pressing rivet nut for an automobile, relates to the technical field of pressing rivet nuts, and aims to solve the problems that after an existing pressing rivet nut and a thin plate are laminated, the limiting effect is poor, and the overall compactness is high. A nut rod is arranged at one end of a supporting disc; a plurality of supporting face convex straight teeth which are annularly distributed at equal intervals are arranged on the face, close to the nut rod, of the supporting disc; semi-elliptic cylinder grooves are formed in the supporting face convex straight teeth; semi-elliptic cylinder inlets are formed in the ends, close to an outer ring of the supporting disc, of the semi-elliptic cylinder grooves; a limiting groove is formed in the upper end of each semi-elliptic cylinder groove; a plurality of nut rod concave straight teeth are arranged at the end, close to the supporting disc, of the nut rod; a bolt inner blind hole is formed in the nut rod; the opening end of the bolt inner blind hole is close to one end of the supporting disc; and the supporting disc, the nut rod and the bolt inner blind hole are integrally formed through cold heading.

Description

technical field [0001] The invention relates to the technical field of rivet nuts, in particular to a lightweight rivet nut for automobiles. Background technique [0002] All countries in the world are implementing policies to force automakers to reduce vehicle fuel consumption. According to research data, if the vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6%-8%; for every 100kg reduction in vehicle weight, fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters, and CO2 emissions can be reduced by about 5g / km. It can be seen that the lightweight of automobiles can improve fuel efficiency and reduce fuel consumption, thereby environmental protection and energy saving. Therefore, automobile lightweight has become the consensus of automobile enterprises. On the premise of ensuring the quality of the car, the use of lightweight auto parts is becoming more and more widespread. [0003] In auto parts, the rivet nut is a kind of nut ...
