Compared with prior art, the present invention has following advantage:
1. solved forging enterprise large-sized flange forging loose tool quality big, use inconvenient, the loose tool cost is big; Make the problem that the cost of flange forging strengthens; Adopt the manufacturing of knockdown large-sized flange loose tool; The quality of upper die and lower die is less, the carrying of loose tool when making things convenient for flange to forge, and the while also reduces the storage difficulty of loose tool; Through the various combination mode of upper die and lower die, can in all patrixes, select, in all counterdies, select counterdie; This just makes that the choice of upper and lower mould is very big; The combination loose tool that obtains alternative different size impression size is just very many, makes existing old loose tool be fully utilized, reuse, and reduces the quantity of making new loose tool in the flange forging; Accelerate the production that flange forges, reduce production cycle and manufacturing cost.
2. make the heavy loose tool of big quality change into both to meet the large-sized flange forging to prepare requirement to have light, advantage relatively flexibly again.
3. the loose tool up and down of four series; Handle through seriation; Profile and interface size to the upper die and lower die of same train are carried out standardization; Guarantee can combination in any with a series of upper die and lower die in; The mistake that causes owing to the size variation when reducing the upper die and lower die manufacturing reduces the tool of production, the kind of cutter, specification when making, thereby reduces the production cost of loose tool; The upper die and lower die that differ bigger for the impression size do not make up the practical significance of pairing, therefore handle through seriation and when satisfying production, have avoided the impression size to differ bigger upper die and lower die again because the outside dimension that needs combination pairing increases.
4. the interface size of loose tool can make up pairing arbitrarily with the upper die and lower die that are designed and manufactured into the same assurance same train in a series of up and down, obtains new impression specification, and the form of interface adopts the mode of cylindrical step to be convenient to manufacture.
