Inclined boss annular forge piece with special-shaped inside and outside and mold of inclined boss annular forge piece

Abstract

The invention discloses an inclined boss annular forge piece with a special-shaped inside and outside and a mold of the inclined boss annular forge piece. The inclined boss annular forge piece with the special-shaped inside and outside and the mold of the inclined boss annular forge piece comprises a special-shaped section ring forge piece body with inclined bosses on the inner diameter and the outer diameter and a mold body for producing the special-shaped section ring forge piece body. A straight and flat boss is additionally arranged on the outer contour of the ring forge piece body, and the straight and flat boss and the special-shaped bosses are in transition through transition corners. The mold body comprises a special-shaped main roll, a blank and a servo core roll, a forge piece cavity is formed in the special-shaped main roll, the blank is arranged between the special-shaped main roll and the servo core roll, and the forge piece cavity is filled with the blank under the action of the special-shaped main roll and the servo core roll. In this way, according to the inclined boss annular forge piece with a special-shaped inside and outside and the mold of the inclined boss annular forge piece, the contact face of the blank and the main roll is added in the production process, so that the ring rolling process is more continuous and stable, the blank is prevented from being subjected to wavy warping or roll climbing well, the folding defect of a ring piece is effectively avoided, and product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of ring forging production, in particular to a ring forging with internal and external special-shaped inclined bosses and a mold thereof. Background technique [0002] The cross-sectional shape of the ring product is as follows Figure 1a and Figure 1b shown, where Figure 1a is the shape of the inner diameter of the inclined boss, Figure 1b For the case where the inclined boss is on the outer diameter. [0003] For special-shaped cross-section rings with inclined bosses on the inner and outer diameters, the forging shape is generally designed with a contour shape similar to the product during production, such as Figure 2a and Figure 2b . [0004] Design special-shaped dies through this form of ring forging, such as Figure 2c Production and assembly drawing of the external special-shaped mold, in which 1 is the special-shaped main roll, 2 is the blank, placed on the reference plane C, and 3 is the ...

AI Technical Summary

Problems solved by technology

[0006] When using the existing design structure for production, due to the uneven wall thickness and size of the billet, the contact surface with the main roll is too small, and the rings often have wavy warping during the ring rolling process, and even roll climbing phenomenon, which usually leads to The product has defects such as wavy warping, outer circle and end face folding, which will lead to product scrapping in severe cases
