Technical field

The utility model relates to U-shaped sealing manufacture field, processing unit (plant) and the processing method of the U-shaped sealing ring of especially a kind of gas turbine.

Background technology

The gas turbine sealing ring is important part in the combustion machine, because in the sound part of combustion machine turbine, the possibility that each inter-stage all exists gas leakage, therefore necessarily require sealing, it mainly acts on is to reduce the gas leakage amount, thereby improves unit efficiency, cut down the consumption of energy.It is " U " type that a kind of sealing ring is wherein arranged, and the sealing ring is because wall is thin, and process very easily deforms, bending and resilience, and the combination springback capacity still the rawness formula calculate, the processing difficulty is big, the extremely difficult quality of holding in the production process.

The utility model content

The purpose of this utility model is processing unit (plant) and the processing method that the high U-shaped sealing ring of gas turbine of a kind of production and processing precision is provided for the deficiency that solves above-mentioned technology.

In order to achieve the above object, the processing unit (plant) of the U-shaped sealing ring of gas turbine that the utility model is designed, it comprises stamping die, integer mould, curved instrument, vehicle clamper and profile of tooth turning cutting tool, described stamping die comprises punch and lower cavity die, last punch top is provided with briquetting, and lower cavity die is formed by connecting by screw by left half module and right half module, is equipped with the half U type indenture in the upper left corner of the left half module upper right corner and right half module, the combination back forms U-shaped indenture, and U-shaped indenture cooperates with briquetting; Described integer mould is cooperated by upper holder block and lower lock block and forms, and is provided with first limited block at lower lock block one end, is respectively equipped with some through holes at upper holder block and lower lock block; Described curved instrument comprises pedestal and U-shaped mould, level is provided with two grooves in the U-shaped mould outside, two flute pitch are consistent with the width of U-shaped sealing ring, pedestal at U-shaped mould one end is provided with second limited block, be connected with handle at U-shaped mould center by rotating shaft, decreased food is greater than U-shaped mode radius, and the handle in the U-shaped mould outside is connected with rotating contact roller; Described vehicle clamper is connected with lathe, and is loop configuration, and loop configuration inside is provided with through hole; Described profile of tooth turning cutting tool arranges two-sided cutting knife-edge, realizes the sealing ring two sides is processed simultaneously, and time processing goes out profile of tooth.

Processing unit (plant) and the processing method of the U-shaped sealing ring of the resulting gas turbine of the utility model can be controlled its machining accuracy effectively to the processing of U-shaped sealing ring.Avoid U-shaped sealing ring in process, to deform, improved the serviceability of U type sealing ring.
