Abstract
The invention discloses a method for machining a thin-wall aluminum alloy part. The method comprises the following steps of: selecting cutters, positioning, performing rough machining, performing semi finish machining, performing ageing treatment, performing standard finish machining, and performing finish machining. By the method, the dimension of the part can be well stabilized, the deformation is reduced, the strength of the part is enhanced, and the cost is reduced.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of processing method of thin-wall aluminum-alloy part.
Background technology
Thin-wall Aluminum Parts is as the important structure part of aviation field, and its shape is done more complicated and more complicated, and dimensional accuracy and fineness require more and more higher, and wall is more and more thinner, and machining has been proposed higher, more fully requirement.
Thin-wall Aluminum Parts, very large on the impact of the machining accuracy of parts and surface smoothness because the impact of the factors such as cutting force, heat in metal cutting, residual voltage stress, clamping power produces machining deformation in process, be easy to cause and scrap.At present, mainly be the intensity that improves part by heat treatment repeatedly, improve cutting ability, and adopt multiple clamping to repair to guarantee the dimensional accuracy of part, although these modes can be improved the machining deformation of Thin-wall Aluminum Parts to a certain extent, complex process, processing cost is high.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide a kind of processing method of thin-wall aluminum-alloy part, can be good at stable dimensions, Reducing distortion improves part strength, reduces cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of processing method of thin-wall aluminum-alloy part is provided, may further comprise the steps:
1) selects cutter: choose the cutter that each process segment needs, it is put into cutterhead in order;
2) location: to be processed employing axially stepped up origin reference location;
3) roughing: select the first cutter, carry out to machined part roughing, remove larger surplus, made allowance 0.6-0.8mm;
4) semifinishing: select the second cutter, the part after the roughing is repaired, made allowance 0.3-0.4mm;
5) Ageing Treatment: the part after the semifinishing is heat-treated actual effect process, eliminate the residual stress of part;
6) benchmark fine finishining: remove the ovality at accurate positioning position, guarantee size and the precision of accurate positioning face;
7) fine finishining: part is machined to given size.
In a preferred embodiment of the present invention, the wall thickness of described thin-wall aluminum-alloy part is 2-8mm.
In a preferred embodiment of the present invention, described semifinishing and described accurately machined processing mode are the processing of great-jump-forward interval.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of processing method of thin-wall aluminum-alloy part, by rational processing technology, adopt the axial location mode, the method of great-jump-forward interval processing, can accelerate the thermal diffusivity of part, accelerate the release of cutting stress, well stable dimensions, Reducing distortion, and improve part strength.
Description of drawings
Fig. 1 is the flow process chart of processing method one preferred embodiment of thin-wall aluminum-alloy part of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also shown in Figure 1ly, the embodiment of the invention comprises:
A kind of processing method of thin-wall aluminum-alloy part may further comprise the steps:
1) selects cutter: choose the cutter that each process segment needs, it is put into cutterhead in order;
2) location: to be processed employing axially stepped up origin reference location;
3) roughing: select the first cutter, carry out to machined part roughing, remove larger surplus, made allowance 0.6-0.8mm;
4) semifinishing: select the second cutter, the part after the roughing is repaired, made allowance 0.3-0.4mm;
5) Ageing Treatment: the part after the semifinishing is heat-treated actual effect process, eliminate the residual stress of part;
6) benchmark fine finishining: remove the ovality at accurate positioning position, guarantee size and the precision of accurate positioning face;
7) fine finishining: part is machined to given size.
Wherein, the wall thickness of described thin-wall aluminum-alloy part is 2-8mm.
Described semifinishing and described accurately machined processing mode are the processing of great-jump-forward interval.
Add man-hour, cutter is made vertically clamping of cutting tool by knife rest, because this radial cutting force of the processing when the thin-wall aluminum-alloy part is minimum, make workpiece not yielding; And adopt the processing of great-jump-forward interval, heat is distributed rapidly, not yielding.
The present invention has disclosed a kind of processing method of thin-wall aluminum-alloy part, by rational processing technology, adopt the axial location mode, the method of great-jump-forward interval processing can be accelerated the thermal diffusivity of part, accelerates the release of cutting stress, good stable dimensions, Reducing distortion, and improve part strength, reduce cost.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
