Being suitable for monolithic base multi-disc assembling process the present invention also provides one kind and is matched with blanking device
Molding die, it includes die ontology, and the multiple blanks one for being provided with and being put into molding die on the die ontology are a pair of
The molding cave answered.
After using above-mentioned technical proposal, the invention has the advantages that：
First multiple blanks are made in material section by 1, monolithic base multi-disc assembling process of the invention, then by multiple blanks
Synchronous grind is expanded into finished product, has not only avoided the low problem of flat-die forging processing efficiency, but also in the same of the geometric tolerance for improving finished product
When avoid subsequent cutting process, generally reduce the processing cost of product；
2, section is expected for the tail portion of some lighter in weight itself, the weight that feeds intake that multi-disc closes forging molding cannot be met, but can be with
It carries out monolithic base and combines tail portion material section to carry out rolling ring molding, improve the utilization rate of material section；
3, monolithic base multi-disc assembling process of the invention is molded using rolling ring so that the deformation of finished product is more equal
Even, interior tissue is more uniformly distributed and possesses beautiful and charming forging flow lines；
4, blanking device of the invention includes centering pincers, before being punched out to material section, by two auxiliary positionings of centering pincers
Outer rim of the point respectively with punching bucket is adjacent to, and dropping place point of the position, that is, punch corresponding to the anchor point of centering pincers in material section carries
The consistency of blank, also improves the outer profile of blank and the concentricity of endoporus, improves product quality in high continuous production.
