In figure: 1-slender axles workpiece, 2-plug A, 3-strengthen plug, 4-low melting point filler, 5-plug B.
Detailed description of the invention
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A processing method for thin-wall long and thin axial workpiece, comprises the following steps:
Steps A, blanking, and the endoporus of slender axles workpiece is processed on request put in place;
Step B, by low melting point filler heating make it fully melt;
Step C, the low melting point filler fully melted is filled the endoporus of slender axles workpiece;
Step D, after the low melting point filler cooled and solidified in endoporus the contour structures of processing slim shaft-like work on request;
Step e, to the slender axles workpiece after processing and the heating of the low melting point filler in endoporus thereof, the low melting point filler in endoporus is made to melt and be separated with workpiece.
Also comprise step F: finish turning is carried out to the endoporus of slender axles workpiece.
In described step C slender axles workpiece endoporus in be also placed with reinforcement plug.
Described reinforcement plug is the hollow structure of end with plug.
Described low melting point filler is low-melting alloy.
Heat medium in described step B and/or step e is hot water or deep fat.
The condensing temperature of described low melting point filler is between 50 DEG C-90 DEG C.
Embodiment:
Utilize this method to certain aviation thin-wall long and thin axle class full size field test, as shown in Figure 1, this part overall length is 1192.6mm, and maximum outside diameter is φ 74mm, and maximum diameter of bore is φ 68mm, and draw ratio is 16:1, belongs to thin-wall long and thin axle class.
Through repeatedly field experiment, and after comprehensively analyzing processes step, carry out detailed adjustment to processing method, cutting parameter, process route, specific implementation method is as follows: the deep hole of first processing slim shaft-like work 1, and reserves allowance for finish; Low-melting alloy filler is melted in the hot water of about 80 DEG C; With plug A2, slender axles workpiece 1 small end is blocked, hold greatly endoporus to erect upward slender axles workpiece 1; Reinforcement plug 3 is put into the endoporus of slender axles workpiece 1, and with plug B5, upper end is covered, avoid filling rear low-melting alloy and flow in plug hole; Pour into low-melting alloy, after natural cooled and solidified, carry out the manufacturing procedure of external structure.Contour structures machines the rear hot water by identical temperature or deep fat and soaks the slender axles workpiece 1 being marked with low-melting alloy filler and be easy to this metal to be separated with workpiece, then carries out the finish turning of endoporus, completes the processing of slender axles workpiece 1.The low-melting alloy filler separated is recyclable to be recycled.
Use low-melting-point metal to fill axial workpiece endoporus first, strengthen the rigidity of workpiece, entirety improves processing characteristics.Part own wt can be strengthened owing to having poured into low-melting alloy in axis hole, flexural deformation to a certain degree can be caused because of dead weight to part during clamping, thus a metallic strength member rod is increased when pouring into low-melting alloy in metal inside, reinforcement rigidity is again played after low-melting-point metal solidifies, the effect of weight reduction, after first being machined by excircle of workpiece, then carry out the finish turning of endoporus.
Finally machining rear part outer maximum of beating is 0.05mm, and Wall-Thickness Difference is 0.03mm, has met designing requirement completely.
Adopt low-melting alloy to fill axial workpiece endoporus, strengthen the rigidity of workpiece, entirety improves processing characteristics.This metal be a kind of multi-element eutectic metal of speciality, containing elements such as Bi, Sn, Pb, In, fusing point is extremely low, and condensing temperature, between 50 DEG C-90 DEG C, can put into production use, and thermal coefficient of expansion is very low after solidifying at once, can ignore.
The present invention solves machining deformation that workpiece produces after digital control processing and the technological innovation that Wall-Thickness Difference cannot ensure, be applicable to all kinds of thin wall shaft part of aeroplane engine, can effectively prevent work in-process due to the poor rigidity of slender axles part own, material is yielding, the problem of the bad guarantee of Wall-Thickness Difference.
