Embodiment Construction

[0010] The present invention will be further described in detail below in combination with specific embodiments.

[0011] The method for forming the end of the side sill of the lower sill plate of the automobile in the present invention, before processing the three faces of the end of the side sill of the lower sill of the automobile side wall through the stamping process, the stress breakage is pre-processed on the sheet metal as the raw material. To destroy the original stress of the sheet metal, the stress failure pit is located in the middle of the middle surface to be processed, and then the three surfaces are stamped and formed, and finally the processed stress failure pit is restored. The three planes are based on the middle plane, the second plane is located at one end of the middle datum plane and bent upwards with an angle of 174o with the middle datum plane, and the third plane is located at the other end of the middle datum plane and bent down with the middle The a...

Abstract

The invention discloses a vehicle side wall lower sill plate edge beam end molding method. Before three surfaces of a vehicle side wall lower sill plate edge beam end are processed through a punching process, a stress damage pit is processed in a sheet metal part as a raw material beforehand to damage original stress of the sheet metal part; the stress damage pit is positioned in the middle position of a middle surface to be processed; and then, the three surfaces are molded through punching. The stress damage pit is an arc pit of which the middle part is deep and the depth is gradually decreased from middle part to periphery. The method can eliminate the defects of difficult processing and poor molding quality caused by material stress in the molding process of the vehicle side wall lower sill plate edge beam end, and improves the processing quality and efficiency.

Description

technical field [0001] The invention relates to the improvement of the processing technology of automobile parts, in particular to a method for forming the edge beam end of the lower sill plate of the automobile side wall, and belongs to the technical field of processing of automobile parts. Background technique [0002] Automobile production involves the machining and welding of many sheet metal parts. Due to the numerous structures and different modeling characteristics of automobile sheet metal parts, different sheet metal parts have different characteristics and technical essentials when processing or welding. Among the many sheet metal parts of the car, there is a part called the end of the side beam of the lower sill of the car side wall. The whole (or roughly) of the part is flat at first glance, but it is actually formed by three surfaces that are roughly on the same plane. The planes are bent in turn to form small angles. Taking the middle plane as the datum, the ...
