Abstract
This graduation design part is a long bar-like holder part of automobile reserve box. Parts of the design process, spare parts for long-bending features, structural design, both considered to ensure that parts forming, and should fully take into account the processing of the mold.
This article is also related to the technical parameters of the calculation, according to the results, the completion of the parts of the three-dimensional model. Finally, UGNX mapping module works to create the appropriate map, for behind the design and manufacture provided the drawings.
It also integrated parts of the forming process and the economy, with actual production, a reasonable set of options: blanking punching, pre-bending, bending flanging, the outer edge of flanging and punching five processes.
According to the design of parts and processing technology, the paper also completed the first three stages of the mold design, including the use of AutoCAD softwar to comple -te the mold assembly and parts of the map drawing. First Vice-use flip-punching compou -nd die blanking the structure of the second vice-mold process for the structure, completed parts of the pre-bend, although the bend radius larger, because only under the proced -ures for preparing, in Design of neglect rebound on the accuracy of forming the third deputy to flanging bending mode, promoting the pressure from the mandril pinched expected to bloc -k the workpiece to prevent the sheet metal forming process of moving.
