Car radiator left and right side plate punching die design
Abstract
Flushes in a technology capability as well as the mold processing characteristic foundation in the analysis￡? from flushes the processing request as well as the economic security aspect embarks￡? uses falls the material and punch to invert the type of compound mold￡? may by time complete falls the material and punch￡? the ramming semifinished materials do not need for the migration￡? has the good craft compatibility￡? flushes a precision to be easy to guarantee￡? is not affected the feeding error￡? inside and outside shape relative position duplication is good. This design basis work piece plane size￡? a reasonable arrangement row of type￡? chooses the appropriate standard sheet￡? and deferred to the corresponding formula separately to determine the drift￡? the concave mold and the convex-concave mold corresponding size and the position relations. Through calculates always flushes the pressure￡? designates the press the model. according to various components characteristic￡? reasonably designs each work components as well as the fixed components￡? and uses the standard letter. Finally￡? carries on the verification to the mold overall form￡? the definite mold closed altitude￡? guarantees the equipment and the standard which selects satisfies the design request.
The design of the main research contents and innovative work as follows:
1. In a lot of reading on the basis of the theoretical literature￡? complete the left and right side of the car radiator blanking punching mold design. On the basis of the autoCaD drawing￡? completed the three-dimensional drawing￡? clearly demonstrated his mold shape.
    2. The design uses a lot of standard parts￡? the purpose is to reduce mold from design to production and processing time and costs￡? in line with the modern mold design and production of efficient and fast principle.
3. From the safe operation and open press body to consider proposed nesting reasonable manner￡? that is￡? first punching a selected sheet￡? according to the needs of the area two workpieces punching down; then under the sheet metal punching flip into the design of composite blanking punching mold process.
Key words: row of type;drift;concave mold;convex-concave mold;closed altitude.
