Angle to improve the forming process and die design
[Abstract] through the angle of the right pieces of process analysis, process improvement of the original program, using a semi-thick symmetrical forming process, simplifying the mold structure is conducive to forming. The improved mold manufacture, maintenance convenience, reduced costs and improved cost-effectiveness.

[Abstract] A correct analysis was made on angle-wrapping parts forming technology. The previous processing scheme has been improved by adopting half-thickness symmetric forming technology, which simplified the die structure and is good for forming. Manufacture and maintenance of the improved die became easier and the cost was lowered. Thus it increased economic benefits.
Key words angle-wrapping parts, drawing, cross-section cutting, technology analysis
Figure 1 is a decorative product angle pieces, materials for the yellow copper, material thickness 1mm, require smooth surface, no, beautiful appearance.
The original material used under (overall) plastic forming edge polishing process, but emerged in the production of the following questions:
(1) the complexity of forming machine blank forms, hand cut expected trouble. The shape of each cut is expected as a result of errors, resulting in blank positioning Drawing inaccurate Blankholder area is too small.
(2) stretch forming wrinkles appear, and even pull off crack phenomenon.
(3) a greater edge burr.
(4) stretching mode and the edge forming the structure of the complex mode, create trouble, wear inconvenient maintenance.
As a result of these problems, the production cause a lot of waste, low yield. In order to reduce costs, meet the mass production angle of the incident to analysis and improvement process.
