Flanging mechanism

Abstract

The invention provides a flanging mechanism. Component edges used for forming a component are perpendicularly folded relative to a component body. The flanging mechanism comprises a fixing assembly for fixing the component body, and an assembly forming surface is arranged on the fixing assembly. The flanging mechanism further comprises a base body and a mounting seat arranged on the base body through a guide assembly, the mounting seat undertakes external force and slide relative to guiding of the base body, a flanging insert is fixedly arranged on the mounting seat, an insert forming surfaceis constructed on the flanging insert, under the driving of the external force, the flanging insert moves with the mounting seat, so that the insert forming surface abuts against the component edges to be matched with the assembly forming surface, and the component edges formed in sequence are bent relative to perpendicular flanging of the component body and one side of the interior of the component body. The flanging mechanism can reduce the influence of flanging springback on the component flanging quality, further can reduce galling phenomenon of the flanging insert on the component in theflanging process, and thus, the flanging quality of the component can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of stamping equipment, in particular to a flanging mechanism. Background technique [0002] In order to facilitate connection and other functions, a large number of automobile sheet metal parts adopt the vertical flanging process. The existing vertical flanging process is difficult to control, and problems such as flanging springback and roughening (burrs on the surface of the component) are prone to occur, which affects the quality of the component. The quality will even affect the mold manufacturing cycle and the time to market of the model. Products with vertical flanging in the existing cold stamping die design process usually adopt the form of direct flanging of the upper die flanging knife block or inclined wedge rollover. [0003] Among them, the vertical flanging of the product is carried out in the form of direct flanging by the flanging knife block. Since there is no springback compensation, the f...

Problems solved by technology

[0003] Among them, the vertical flanging of the product is carried out in the form of direct flanging by the flanging knife block. Since there is no springback compensation, the flanging of the component may affect the final flanging effect due to springback, and in the flanging process, In order to reduce springback, the distance between the flanging knife block and the fixed component of the fixed component is usually set to be smaller than the thickness of the component. At this time, the surface of the component is prone to defects such as scratches and burrs, and the inclined wedge rollover Although it can have a certain degree of springback compensation, but in the form of a wedge rollover, the distance between the knife block and the fixed component still needs to be smaller than the thickness of the component, and defects such as scratches and burrs on the surface of the component will also occur.
