Shaping die for manufacture of gas turbine seals and manufacture process of gas turbine seals

Abstract

The invention provides a shaping die for manufacture of gas turbine seals and a manufacture process of the gas turbine seals and belongs to the field of machining. The shaping die comprises a left moving core, a right moving core, a fixed die, guide posts and a base. The base is fixed on a base of a hydraulic press. The fixed die is fixed on the base. Left and right profiles of the fixed die match with a toothed surface profile of a seal; the fixed die is provided with teeth matching with those of the seal. The left moving core and the right moving core are disposed on two sides of the fixed die and fixed on a horizontal cylinder of the hydraulic press. The right surface profile of the left moving core and the left surface profile of the right moving core are matched with the smooth surface profile of the seal. The shaping die for manufacture of the gas turbine seals and the manufacture process of the gas turbine seals have the advantages that the inside and outside of the seal manufactured with the shaping die and by the manufacture process are free of flaw, the various specified requirements can be met, the shaping die and the manufacture process are fully adaptable to ultrahigh temperature and high pressure environments, and the seal never fails when a gas turbine operates.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a gas turbine sealing plate setting mold and a manufacturing process. Background technique [0002] Gas turbine is an advanced and complex complete set of power machinery equipment, and it is a typical high-tech intensive product. As a high-tech carrier, the gas turbine represents the comprehensive level of development of multiple theoretical disciplines and multiple engineering fields, and is one of the important symbols of the country's high-tech level and scientific and technological strength, and has a very prominent strategic position. [0003] The gas turbine seal is one of the most important components in the gas turbine. It operates in an environment of ultra-high temperature and high pressure. The whole process of the seal is the fundamental guarantee of the quality of the seal. If the seal is flawed during the manufacturing process, it will cause Major equipment fa...

[0003] The gas turbine seal is one of the most important components in the gas turbine. It operates in an environment of ultra-high temperature and high pressure. The whole process of the seal is the fundamental guarantee of the quality of the seal. If the seal is flawed during the manufacturing process, it will cause major equipment failure

[0004] Figure 1-Figure 3 It shows the structure of a gas turbine sealing sheet. Since there is no precedent for making such a sealing sheet in China, there is no mold and manufacturing process for this sealing sheet in the prior art.
