Square insert forging die with double-sided finish forging impression

Abstract

The invention relates to a square insert forging die with a double-sided finish forging impression. A double-sided finish forging impression structure of the square insert forging die is realized under existing die forming hammer die forging conditions, use functions of the insert forging die is expanded, and the service life of the insert forging die is prolonged. An upper die of the square insert forging die comprises a fixed key slot (1), a jaw (4), a blanking impression (5), a flash cavity (6) and two finish forging impressions (7). The fixed key slot (1) is positioned at the upper end of the upper die, the left side and the right side of the upper die are provided with positioning fixed faces including positioning standard faces (2) and fixed slopes (3), the two finish forging impressions (7) are arranged on the upper die by means of an avoidance method, namely the two finish forging impressions (7) are in staggered arrangement in vertical and bilateral directions, the vertical center lines of the two finish forging impressions of the upper die are not on the same vertical plane, one of the finish forging impressions (7) is positioned on the upper end face of the upper die, and the other one of the finish forging impressions (7) is positioned on a splitting face of the upper die.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a square insert forging die with a double-sided final forging die cavity. Background technique [0002] Existing 1-5 ton die forging hammer upper die forging, widely used square insert forging die and round insert forging die. The square insert forging die includes an upper insert die (abbreviated as the upper die) and a lower insert die (referred to as the lower die). And double-sided slope positioning structure, the above structure needs to use key block and wedge iron or directly use wedge iron to install and fix the square insert forging die in the square insert mold base, in which the insert mold base, key block And wedge iron is a common structure for installing and fixing square insert dies, and different die forgings need to use correspondingly different square insert forging dies. [0003] The upper die or the lower die of the existing square insert forging die is a si...

AI Technical Summary

Problems solved by technology

[0003] The upper die or the lower die of the existing square insert forging die is a single-sided final forging die chamber structure, that is, only one side of the upper and lower sides of each upper die or lower die has a final forging die chamber, that is, single-sided final forging Die chamber, square insert forging die with one-sided final forging die chamber has few functions and low service life

In addition, due to the limitation of the insert structure and the positioning reference of the square insert forging die, it is difficult for the upper die and the lower die to realize the double-sided final forging die cavity structure.
