Abstract

The invention discloses a heat shaping fixture and a heat shaping method in the quenching process of a metal material seal ring, and relates to a heat shaping fixture and a heat shaping method in the quenching process of a seal ring. The invention solves the problems that the integral hardness of a seal ring cannot be improved, the opening size cannot be ensured and waste products are easily produced in the conventional quenching technology. The device comprises that: an upper cover plate and a bottom plate are vertically aligned; a wedge block is nailed in an inclined hole of each shaft; the shaft is sleeved with number adjustable gaskets; the metal material seal ring is arranged between the upper cover plate and the bottom plate; an oil immersion hole on the upper cover plate corresponds to the upper end face of the metal material seal ring; and an oil immersion hole of a lower cover plate corresponds to the lower end face of the metal material seal ring. The method comprises the following steps of: clamping the seal ring in the heat shaping fixture; putting the seal ring and the heat shaping fixture into a heat treatment furnace, and completing quenching and tempering procedures of the heat treatment, which meet the hardness requirement; and detaching the heat shaping fixture and taking the seal ring out. The invention is used for heat shaping in the quenching process of the metal material seal ring.

Description

technical field [0001] The invention relates to a heat-setting fixture and a heat-setting method in the quenching process of a sealing ring, in particular to a heat-setting fixture and a heat-setting method in the quenching process of a metal material sealing ring, and belongs to the technical field of heat treatment. Background technique [0002] There are several sealing rings with different specifications in the parts of the gas turbine. The characteristics of the parts are: the dimension in the direction of the outer diameter is much larger than the height and wall thickness of the parts. It is required to achieve quenching hardness during heat treatment and improve the strength of the whole part. Due to the high hardness after quenching, there is only a small grinding allowance after quenching, which requires that the sealing ring not only achieve the required quenching hardness, but also ensure the opening size and small The amount of deformation, and try to reduce th...
