Abstract
The invention relates to a manufacturing method used for manufacturing a non-redundancy blade rolling mould, belonging to the mould processing filed. The manufacturing process is sequentially carried out according to the following steps: roughcast is forged, which adopts a three-time forging and three-time drawing; a single side redundancy of 3 to 5mm is preserved ahead in a raw processing; a moulding surface is controlled by an NC milling machine to a benchmark positioning, with a 0.3mm single redundancy of the moulding surface; a heat treatment is carried out to lead the hardness to reach HRC58-62; an internal hole is processed and an assembling size is processed; the moulding surface is milled fine again to preserve a 0.2 to 0.3mm redundancy; a milling and grinding is carried out by anNC system and a manual process; a magnetic force flaw detection is carried out in the end. The processing method has high accuracy and lower surface corrugation degree, and can manufacture a mould with equal structure and high anti-pressure strength.
Description
Technical field
The invention belongs to metal cold working field, particularly about making the molded making method of rolling that no-residual length leaf uses.
Background technology
Making no-residual length leaf employing cold working rolling method is present a kind of new technology, wherein the rolling mould is that cold rolling blade is out of shape key instrument, making most drawing and the special-purpose models of relying on of rolling mould at present makes by hand, the result is that labour intensity is big, mould and die accuracy is low, and the product percent of pass that goes out with this mould is low, the cost height, do not satisfy new work engine, the specification requirement of high-pressure compressor blade.
Summary of the invention
At the prior art weak point, the invention provides a kind of mould even tissue, compression strength is big, rolls mould precision height, and is little by the rolled piece surface waviness, and long service life is suitable for the manufacture method of a kind of non-machining leaf blade roll milling mould of suitability for industrialized production.
The technical solution adopted for the present invention to solve the technical problems is to carry out according to the following steps
(1) blank forging;
(2) roughing blank;
(3) rolling model face is milled in the roughing numerical control;
(4) heat treatment;
The benchmark of (5) fine finishining rolling model face;
(6) processing outline;
(7) rolling model face is milled in the fine finishining numerical control;
(8) finish to gauge rolling model face, dyeing inspection applying degree is not less than 75%;
(9) rolling model face is checked;
(10) the rolling mould is carried out magnetic crack detection.
Wherein blank forging is the Cr12MoV blank to be carried out three big and heavy stones three pull out and handle to form the circle base, and carries out the carbide segregation inspection, changes over to down after qualified and goes on foot operation; Roughing blank material is to remove the blank surplus, monolateral made allowance 3~5mm, and the benchmark of inspection rolling model face meets the requirements and changes down the step operation over to; It is to locate with the benchmark of roughing rolling model face that rolling model face is milled in the roughing numerical control, roughing rolling model face on annulus, and it is 0.3mm that rolling model face list size is reserved surplus, changes down the step operation over to after inspection meets the requirements; Heat treatment is that the made blank of rolling model face is milled in the roughing numerical control, heat-treats.Hardness is HRC58~62, changes down the step operation over to after inspection meets the requirements; Fine finishining is that the endoporus of the rolling mould blank after the heat treatment and the fitted position of two sides are carried out fine finishining, changes down the step operation over to after inspection meets the requirements; The processing outline is that the blank through roughing rolling model face is cut into 3 rolling die topography profiles, changes down the step operation over to after inspection meets the requirements; It is that the rolling mould after the cutting is contained on the anchor clamps that rolling model face is milled in the fine finishining numerical control, on high-speed milling machine, uses carbide-tipped milling cutter, finish-milling rolling model face, and rolling model face size surplus is 0.2~0.3mm, changes down the step operation over to after inspection meets the requirements; The blank of finishing to gauge rolling model face and being milling through the fine finishining numerical control behind the type is contained on the special-purpose cubing, manually carry out correction of the flank shape, the gap that check result should meet between model and rolling model face is not more than 0.02mm, dyeing inspection applying degree is not less than 75%, surface roughness is Ra0.1~0.2, in order to guarantee the percent ripple of blade, require the adjacent two sections Y direction variation in the rolling model face to be not more than 0.01mm, whole rolling model face Y direction variation is not more than 0.02mm, changes down the step operation over to after inspection meets the requirements; Magnetic crack detection is that the rolling mould that produces through 1~8 step is carried out magnetic crack detection, and the result mustn't have crackle.
Good effect of the present invention is: the mould even tissue, and compression strength is big, rolls mould precision height, and rolling mould surface waviness is little, and long service life is suitable for the manufacture method of a kind of non-machining leaf blade roll milling mould of suitability for industrialized production.
