Embodiment Construction

[0012] A die forging forming method of a mounting seat, which adopts a process route of pre-forging, final forging, and hot shaping. Firstly, a pre-forging die 1 is used to pre-forge a blank, and then a final forging die 2 is used to pre-forge the pre-forged pre-formed The forging is final forged, and finally the forging after final forging is thermally shaped; the pre-forging die 1 has a structure of one die and two cavities, and the pre-forging die 1 has two forming cavities 4, and the two forming cavities 4 mirror Symmetrical connection; after the pre-forging is completed, the pre-forging is divided into two mounting seat pre-forgings, and then the final forging die is used to perform final forging on the two mounting seat pre-forgings, and finally the two forgings after final forging are heat-treated plastic surgery. The final forging die 2 is a one-mold-one-cavity structure. figure 2 Among them, 5 is the upper die of the pre-forging die, and 6 is the lower die of the pr...

Abstract

The invention provides a die forging molding method for a mounting seat, which can effectively solve the problems of difficult positioning of a blank in a forging die and lateral force during die forging in the die forging process. The die forging molding method for the mounting seat is characterized by adopting a pre-forging, final forging and thermal finishing process path and comprises the steps of performing pre-forging molding on the blank by adopting a pre-forging die, then performing final forging molding on the forging subjected to the pre-forging by a final forging die, and finally performing thermal finishing on the forging subjected to the final forging molding, wherein the pre-forging die has a one-die two-cavity structure, and two molding cavities of the pre-forging die are arranged and are symmetrically communicated in a mirror image mode.

Description

technical field [0001] The invention relates to the field of die forging forming of superalloys, in particular to a die forging forming method of a mounting seat. Background technique [0002] A mount for an aero-engine, the structure of which is shown in figure 1 As shown, its outline size is 227.6×206.8×37.3mm (length×width×height). 5.2mm, and the tail 3 is warped by 42°, which belongs to the thin-walled complex structure. The following problems exist in the die forging process: (1) The shape of the forging is strange, and the blank of the forging is a slab, so the blank is not easy to locate in the forging die during die forging; (2) The tail of the forging has a large degree of warpage, It is easy to generate a strong lateral force during die forging, resulting in a relatively thick tail position and a large displacement of the forging. Contents of the invention [0003] In view of the above problems, the present invention provides a die forging forming method of th...
