Abstract

The invention discloses a rapid prototyping device for special-shaped sheet metal parts, and relates to rapid prototyping equipment for sheet metal parts. The rapid prototyping device comprises an upper die base, a concave die which is clamped inside the upper die base, a lower die base, a forming support terrace die which is fixed on the lower die base and matched with the concave die, the concave die is a concave die with a semi-closed cavity, a rubber plate is arranged inside the concave die with the semi-closed cavity, the thickness of the rubber plate is less than the depth of the semi-closed cavity, a forming workpiece feta membrane for supporting a workpiece to be machined is fixedly arranged on the forming support terrace die, and a pressure elevating mechanism is connected to the upper die base. According to the rapid prototyping device for special-shaped sheet metal parts, the surfaces of the obtained parts are smooth and flat, and the defects of indentation, scratches and convex-concave shapes appearing on the surfaces of the parts when the traditional methods are used for forming the parts are resolved.

Description

technical field [0001] The invention relates to rapid prototyping equipment for sheet metal parts, in particular to a rapid prototyping device for special-shaped sheet metal parts. Background technique [0002] Sheet metal forming is to apply external force to metal wool such as thin plates, thin-walled profiles and thin-walled pipes to cause plastic deformation or shearing, so as to become a part processing method with expected shape and performance. [0003] In the existing sheet metal forming process, many parts with special-shaped surfaces need to use mold tires when forming, and they are repeatedly corrected on the mold tires by manual beating. The part surface after processing in this way leaves traces left when beating, and the part surface is uneven, and the surface quality is poor; and the labor intensity of the workman is also very large. Contents of the invention [0004] The purpose of the present invention is to provide a rapid prototyping device for special-...
