Abstract

The invention discloses a chambering tool which comprises a mandrel supporter, a core rod (1) and an upper mold flat anvil (2), wherein the core rod (1) is distributed with a plurality of first resistant teeth (11) axially; a first resisting groove (12) is formed between two adjacent first resisting teeth (11); and the plurality of first resisting teeth (11) are distributed along the circumference direction of the core rod (1). According to the invention, the core rod is designed according to the characteristics of forged ring metal in chambering, the resisting groove is designed, the contactarea of the forged ring and the core rod is increased, the flow direction of the deformed metal is changed, the chambering tool is favorable for restricting the tangential flow of the metal, the axial flow of the metal is promoted, and the axial performance of the forged ring is improved obviously, thus the axial performance (tension force and impact toughness) substantially exceeds the radial performance, and reaches or close to the tangential performance. Compared with the national military standard or American standard ASTMB247, the axial performance can be improved by 40%-80%.

Description

technical field [0001] The invention relates to the technical field of ring forging, in particular to a hole reaming tool. Background technique [0002] Forging forming refers to applying external force to the metal to cause plastic deformation of the metal, changing the shape and size of the blank, improving its internal structure and mechanical properties, and obtaining a blank or part with a certain shape, size and performance. Forging forming and stamping forming are referred to as forging, which are part of the metal pressure processing production method. [0003] Adopting the traditional horse frame, mandrel, and flat anvil reaming method, the contact surface of the forging ring is flat, the contact surface resistance is small, and the metal is easy to flow in the tangential direction, so the tangential performance of the forging ring is the highest, followed by the radial performance. Lowest axial performance. [0004] In addition, for large forging rings, especiall...
