Abstract
The invention discloses a forming method for an automobile panel sample, which is characterized in that the forming method for the automobile panel sample combines the working steps of preforming and finishing, firstly, a preformed sample is formed by the aid of a mould obtained by a concrete pouring method, and secondly, a finished sample is obtained by means of single point incremental forming, and at least one of a female mould, a male mould and a blank holder of the forming mould for the preformed sample is manufactured by means of concrete pouring. The forming method for the automobile panel sample has the advantages of low mould cost, short sample development period and capability of meeting requirements on precision.
Description
technical field [0001] The invention relates to a method for forming a part, in particular to a method for forming a sample of an automobile cover part. Background technique [0002] Automobile panels (referred to as panels) refer to the auto parts that make up the car body or cab, cover the surface and interior of the special-shaped body of the engine and chassis. The car cover is not only a decorative part, but also a closed shell-shaped force-bearing part. Specifically, the car cover includes the engine cover, the roof cover, the left and right side panels, the front and rear doors, the front, rear, left and right fenders, the suitcase cover, the engine front support plate, the engine front Apron, cowl top, rear apron, rear apron, front apron, front frame, front fender, wheel fender, rear fender, rear apron, luggage compartment cover, rear Cowl, top cover, cowl side panel, cowl panel, cowl top cover, front fender, engine cover, etc. Any tiny defects on the surface of t...
