A Blade Forging Die Convenient for Detecting the Misalignment of Forgings

Abstract

The invention discloses a blade forging die facilitating detection of offset of a forged piece. The blade forging die comprises an upper die and a lower die, wherein at least two upper inserts used for detecting offset are fixed on the upper die, an upper offset groove is formed in each upper insert, and the end surfaces of the upper offset grooves are flush with the end surface of the upper die; at least two lower inserts used for detecting the offset are fixed on the lower die, a lower offset groove matched with the corresponding upper offset groove is formed in each lower insert, and the end surfaces of the lower offset grooves are flush with the end surface of the lower die; each offset groove comprises four side groove surfaces and one bottom groove surface, and the four side groove surfaces of each offset groove all adopt a planar structure. During forging, an offset block blank made of a metal material is put in each offset groove. The inserts are arranged on the die, the offset grooves with the side groove surfaces adopting the planar structure are formed in the inserts, all that is required for determination of offset of the forged piece is to detect the offset of an offset block forged along with the forged piece, operation is convenient and simple, and the offset detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to a die, in particular to a blade forging die which is convenient for detecting the displacement amount of a forging. Background technique [0002] During the blade forging process, the force of the blade forging die is relatively complex, and the huge forming force will inevitably lead to a large lateral force on the die, which will lead to misalignment between the upper and lower dies. In actual production, due to the complex structure of the blade, the profile of the blade body is greatly distorted. At the same time, it is very difficult to detect the amount of mold misalignment caused by the irregular shape of the blade root, boss, and blade crown, and the detection time is long. If the misalignment If it is too large, it even needs to re-test forging, which greatly reduces the efficiency of the forging workshop. Therefore, it needs to be solved urgently.
