Abstract

The invention provides a burr removal device for a mortise outlet. The burr removal device comprises a chip breaking ring which is of a circular ring structure, and the chip breaking ring is fixed tothe part below a cleaned plate-part; through arrangement of the chip breaking ring below the plate-part, the outlet end, during broaching of a mortise, extends to the position of the chip breaking ring, so that hard burrs are not liable to generate at the outlet end of the plate-part and the depth of a lattice deformation layer is reduced effectively; and thus the service life of the plate-part isprolonged.

Description

technical field [0001] The invention belongs to the technical field of machining process equipment, and in particular is a burr removal device for tongue and groove outlets. Background technique [0002] The disc parts with axial tenons in the engine are mostly processed by broaching. At present, the materials of disk parts mainly include high-temperature stainless steel, superalloy, titanium alloy and powder metallurgy alloy. When the material of the disc is high temperature alloy or powder metallurgy alloy, there will be burrs at the outlet of the tenon and groove when the tenon and groove are broached. When passing through the outlet of the tongue and groove, the base material of the part is taken out, which deepens the lattice deformation layer of the outlet of the tongue and groove on the part. In the subsequent passivation process of the sharp edge, the deformed area cannot be completely removed, resulting in a stress concentration area, which seriously affects the pr...
