Abstract
The invention provides a method for cutting flashes of a blade forged piece, which can solve the problem that the profile of a blade forged piece deforms seriously when an edge cutting mold is used for cutting edges conventionally, and eliminate a thermal shaping procedure of the forged piece the edge of which is conventionally cut. The method is low in processing cost and high in production efficiency is high, and can guarantee the size stability of the profile of the blade forged piece. The method is characterized by cutting and removing the flashes of the blade forged piece by a water jet cutting machine, and comprising the following processing steps that: (1) a special water jet cutting clamp is arranged on an operating platform of the water jet cutting machine; (2) the blade forged piece to be processed is positioned on the water jet cutting clamp; (3) a numerical control program on water jet cutting is programmed to perform the water jet cutting on the flashes of the blade forged piece to be processed; and (4) the blade forged piece the flashes of which are cut is detected, and then flows to a next procedure.
Description
Technical field
The present invention relates to the processing technique field of blade forging, be specially a kind of overlap cutting method of blade forging.
Background technology
The blade forging has the overlap 9 that all thickness is 5mm～15mm after forging, see Fig. 1, conventional overlap processing method is to adopt shaving die to utilize die point with the blade cutting burrs at forcing press, the method can cause the gross distortion of blade forging profile, therefore after side cut, also need forging is carried out hot shaping, and hot shaping has not only improved processing cost, has reduced production efficiency, but also can cause the unstable of blade forging molding surface size.
Summary of the invention
For the problems referred to above, the invention provides a kind of overlap cutting method of blade forging, it can solve the conventional serious problem of blade forging profile distortion that adopts the shaving die side cut to exist, thereby can save the conventional afterwards hot trimming of forging of cutting edge, processing cost is low, production efficiency is high, and can guarantee the stable of blade forging molding surface size.
Its technical scheme is such, it is characterized in that: it adopts water-jet cutting machine that the blade forging overlap is cut removal, and it comprises following procedure of processing:
(1) dedicated water cutter cutting clamper is installed on the described water-jet cutting machine workbench;
(2) blade forging to be processed is positioned on the described water cutter cutting clamper;
(3) behind the establishment water cutter cutting numerical control program described blade forging overlap to be processed is carried out the cutting of water cutter;
(4) blade forging after the overlap cutting is detected, then flow into later process.
It is further characterized in that: pressure-air mixing water and diamond dust are adopted in the cutting of described water-jet cutting machine.
With the employing shaving die of routine the method that blade forging carries out cutting burrs is compared, the beneficial effect of the inventive method is: it adopts water-jet cutting machine that blade forging is carried out cold cut and cuts, because its cutting adopts pressure-air mixing water and diamond dust vertically to cut, thereby cutting force is concentrated, cutting deformation is little, therefore do not need to carry out again hot shaping after the cutting of blade forging overlap, and its stock-removing efficiency is high, average cutting speed is 200mm/min, thereby can greatly improve working (machining) efficiency, and can guarantee the stability of the size of profile, reduce the forging production cost.

The specific embodiment
See Fig. 2, processing method of the present invention comprises following procedure of processing:
(1) dedicated water cutter cutting clamper 1 is installed on the workbench 3 of water-jet cutting machine 2;
(2) blade forging 4 to be processed is positioned on the water cutter cutting clamper 1;
(3) establishment water cutter cutting numerical control program is treated machining blade forging 4 overlaps and is carried out the cutting of water cutter, and pressure-air mixing water and diamond dust are adopted in its cutting during the cutting of water cutter, and the blade forging overlap is vertically cut;
(4) blade forging after the overlap cutting is detected, then flow into later process.
See Fig. 3, Fig. 4 and Fig. 5, the dedicated water cutter cutting clamper in the inventive method comprises common bottom plate 5, and the two ends of general degree plate 5 are separately installed with integral shroud positioning seat 6 and blade root positioning seat 7, and axial location piece 8 is installed on the madial wall of blade root positioning seat 7.During use, first with apparatus of the present invention clamping of assembling on water-jet cutting machine workbench 3, then blade forging 4 is positioned in apparatus of the present invention, wherein blade root positioning seat 7 and integral shroud positioning seat 6 are distinguished blade root position and the integral shroud position of positioning supports blade forgings, and axial location piece 8 cooperates blade intermediate upper surface axial location.This dedicated water cutter cutting clamper, its by integral shroud positioning seat and blade root positioning seat along mould to positioning supports turbine blade forging, thereby effectively avoided blade forging profile and positioner to the interference of water cutter cutting overlap cutter track, also improved the efficient of water cutter cut-off blade forging flash; And the axial location piece of installing on the madial wall of blade root supporting seat cooperates with blade root intermediate upper surface, has further guaranteed the reliable location and installation of blade forging.
Among Fig. 2,10 is the water cutter shower nozzle of water-jet cutting machine.
Claims (2)
