Embodiment Construction

[0014] The method for preventing misalignment of die forgings with complex profiles according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0015] Such as figure 1 and figure 2 and image 3 and Figure 4 As shown, it is a die forging 1 whose shape is a revolving body. Its inner cavity 2 is deep and its structure is relatively complicated, and it needs to be formed after multiple times of die forging.

[0016] In order to prevent inaccurate alignment of blanks when entering the mold between fires, the following methods are adopted to prevent misalignment of die forgings with complex profiles:

[0017] (1) if Figure 5 As shown, the inner wall of the mold cavity 12 of the lower die 11 of the complex profile die forging is processed with a groove 14 communicating with the parting surface 13, and the upper dimension of the groove ...

Abstract

The present invention discloses a method for preventing complex moulding surface die forging from producing mismatch. Said method includes the following process: (1), in inner wall of die cavity of lower die of die forging with complex moulding surface processing recessed groove communicated with die parting face, and on the edge of die parting face of die forging forming projection matched with the above-mentioned recessed groove; (2), when the die stamping process is made, utilizing the above-mentioned recessed groove and projection to implement accurate positioning; and (3), after the die forging is processed, the described projection can be buffed away.

Description

technical field [0001] The invention relates to a processing method for a die forging with a complex profile, in particular to a method for preventing misalignment caused by repeated processing of a rotary die forging with a complex profile. Background technique [0002] Aluminum alloy die forgings with a revolving shape and a very complex inner cavity size require multiple forgings to form during the production process. Since the shape of this mold segment is a revolving body, it is difficult to ensure the accuracy of the alignment when the billet is put into the mold between each fire, and if the alignment is inaccurate or misplaced when the billet is put into the mold between each fire, it will cause the inner cavity of the product to break. Misalignment will cause folding, which will cause the product to be scrapped if it is serious. Contents of the invention [0003] Aiming at the alignment problem during the production of complex-shaped die forgings whose shape is a...
