Description

Combined stamping die

The utility model belongs to the combination diel, particularly relates to a kind of large-scale thin plate combination diel.

The manufacturing of existing large-scale sheet stamping mould is generally adopted three coordinate CNC milling machines, spark forming, methods such as hot investment casting.These existing processing methods exist many defectives and not enough as: because large-scale sheet stamping die size is bigger, stamping products is complex-shaped, therefore mould manufactures and designs the comparison difficulty, need the high accuracy process equipment, and its machining accuracy is difficult for guaranteeing, its process-cycle is longer, and manufacturing cost is higher.Be overall structure in mould simultaneously, also be not easy to loading and unloading, transportation and keeping.

The purpose of this utility model is, overcomes existing above-mentioned defective in the existing diel manufacturing, and a kind of machining accuracy height is provided, and manufacturing process is simple, and the process-cycle is short, the combination diel that cost is low.

The major technique of combination diel described in the utility model is characterized as, and this mould includes convex patrix and spill counterdie, and upper die and lower die are made up of polylith template shape respectively, and this polylith template connects and composes upper and lower mould respectively by one group of bolt.

Combination diel major advantage described in the utility model is, can make the diel of various complicated shapes, the machining accuracy height, and manufacturing process is simple, and is with short production cycle, and cost is low; Its assembling, decomposition conveniently are convenient to transportation and keeping.
