Abstract
The invention discloses a blade root slope processing method of a turbine medium-pressure first-stage movable blade, relates to a blade root slope processing method, and specifically relates to a blade root slope processing method of the turbine medium-pressure first-stage movable blade. The problems that the existing blade root slope processing method of the turbine medium-pressure first-stage movable blade is long in processing period, great in devoted machine tool and great in labor intensity are solved. The specific steps of the processing method are as follows: installing a workpiece on a high jaw of a machine jaw vice, installing the machine jaw vice on the table-board of the machine tool, and installing a disc milling cutter on a machine tool spindle; and starting the machine tool, processing the inner radial surface and the back radial surface of the workpiece by the disc milling cutter, wherein the cutting depth of the machine tool spindle is 0.1mm-2mm, the cutting speed is 0.1mm/min-15mm/min, and the rotating speed of the machine tool spindle is 70rpm-80rpm, after finishing the processing, dismounting the workpiece from the high jaw of the machine jaw vice. The processing method disclosed by the invention is used for processing the blade root slope of the turbine medium-pressure first-stage movable blade.
Description
Technical field
The present invention relates to blade root oblique surface machining method, be specifically related to press in steam turbine one-level moving vane blade root oblique surface machining method.
Background technology
At present, in the ultra supercritical unit, middle pressure one-level moving vane used is the environmental requirement of satisfying high temperature, high pressure, generally adopts the special material of R-26.The fundamental characteristics of this material is that hardness 262～331, tensile strength are greater than 1000, and the hardness of the blade material 1Cr12Mo of daily processing is 229～255, tensile strength is greater than 685, both contrasts are apparent, the R-26 material adds process to machine and has proposed very high requirement, original processing technology is for utilizing numerical control horizontal milling machine processing, this scheme is difficult to realize the processing and manufacturing of product in the following aspects, 1, this technological requirement is used the molded line cutter, but also there is no to process at present this kind cutter of R-26 material; 2, can't large tracts of land use sleeping milling machine tool process this product, 3, the process-cycle is long, human resources consumption is large.
Summary of the invention
The present invention is that in the existing steam turbine of solution, the pressure one-level moving vane blade root oblique surface machining method process-cycle is long, input lathe amount is many, the problem that intensity of workers is large, and then press one-level moving vane blade root oblique surface machining method in the proposition steam turbine.
The present invention addresses the above problem the technical scheme of taking to be: the concrete steps of processing method of the present invention are as follows:
After step 3, completion of processing, unload on the high jaw with workpiece slave vice.
The invention has the beneficial effects as follows: the present invention only need drop into four lathes just can guarantee the process-cycle of four days, shortened and pressed the process-cycle on one-level blade root inclined-plane in the steam turbine, reduced processing cost, reduce the input amount of lathe, reduced workman's labour intensity, the present invention is simple to operate, and the working time is short, labour intensity is low, has saved a large amount of processing costs; The present invention is merged into a procedure with original two procedures, uses a machine tool just to complete the processing of product, has avoided dropping into more lathe and personnel.
