Quench hardening shaping fixture for metal-material super-thin opening annular element

Abstract

The invention discloses a quench hardening shaping fixture for a metal-material super-thin opening annular element, relates to a shaping fixture, and aims to solve problems that because an opening annular element forms larger stress in quenching and tempering processes, the opening annular element has large deformation and the opening size of the opening annular element cannot be guaranteed. A shoulder is processed on a base plate; the diameter of the upper part of the base plate is smaller than the diameter of the lower part of the base plate; the press plate is composed of a press plate main body and a press ring; the press ring is fixedly mounted on the outer edge of the lower end face of the press plate main body; the press plate main body and the press ring are made into a whole; a press plate covers the upper end face of the base plate; the press ring is sleevedly mounted on the upper end part of the base plate; the base plate and the press plate are each provided with 16-24 U-shaped grooves along the circumferential direction in a processing mode, and the U-shaped grooves are processed in an up-and-down corresponding mode; a strip-shaped through hole is processed on each of locking shaft pins; the base plate and the press plate are locked tightly through the locking shaft pins; each strip-shaped through hole is provided with a wedge block; central through holes are correspondingly respectively processed on the base plate and the press plate, and the central through hole of the press plate is provided with a hinge. The fixture is used for quench hardening shaping of the metal-material super-thin opening annular element.

Description

technical field [0001] The invention relates to a hardening and shaping fixture, in particular to a hardening and shaping fixture for an ultra-thin open ring piece of metal material. Background technique [0002] The design of ultra-thin open rings made of metal materials requires high hardness and size requirements for the opening. Due to the high hardness of the open ring, the cutting cannot be realized, and it can only be realized by grinding. If the grinding allowance is too much, the first is the increased grinding difficulty, and the second is that the parts will be seriously deformed during the grinding process. , so the margin left before the final heat treatment is generally only tens of microns. [0003] The open ring part needs to be hardened, that is, tempered at low temperature after quenching, the quenching temperature is very high and requires rapid cooling, so a large stress is formed, resulting in large deformation of the open ring part, which cannot meet t...
