Abstract
The invention discloses a partial bulging device of a high-temperature alloy flange for an aircraft engine. The device is characterized by comprising a base, a base clamping block, bulging blocks, a core part clamping block, a mandrel slide block and a guide rail, wherein the mandrel slide block is mounted between each bulging block and the core part clamping block in a sleeved manner and is in planar matching with the corresponding bulging blocks based on a certain inclination angle; the mandrel slide block can downwards move along a shaft under the external force effect and can extrude the bulging blocks to bulge in the radial direction along the guide rail, so as to achieve the purpose of bulging. The partial bulging has the characteristics that the matching degree of the mandrel slide block and each bulging block can be different, and the matching angles range from 80 to 88 degrees. The device is mainly applied to the production of the high-temperature alloy flange for the aircraft engine.
Description
Technical field
The present invention relates to a kind of bulging device, particularly a kind of local bulging device of aero-engine high temperature alloy mounting edge.
Background technology
Mounting edge is a kind of part common in aero-engine, and be a kind of fan-shape polygon frame Structure type part, the sectional area of its each frame is all not identical, eachly belongs to complex class structural member.Because the cross section difference of mounting edge is large, the difficulty of shaping is very large, and production efficiency is low, and material consumption is very large.For a long time, all continue to use head of a bed manufacturing process to the making of such part both at home and abroad, waste of raw materials is serious, production efficiency is low, and series-produced mounting edge uniformity is poor.
Chinese invention patent description CN102441604A disclosed in 9 days Mays in 2012 discloses a kind of Thermal expansion method of aluminium alloy special-shaped ring rolled piece, wherein refer to a kind of bulging device, this device forms primarily of mandrel slide block, radial slider, bulging block, workbench and guide rail.Mandrel slide block conically and be sleeved in radial slider and coordinate with the tapering inner circumferential face of radial slider, mandrel slide block can be driven by the hydraulic cylinder of shape expanding machine and to move up and down vertically in radial slider and extruding radial slide block, and the guide rail that radial slider is arranged on shape expanding machine can move around along guide rail radial direction.When adopting this bulging device to carry out bulging to annular forging piece, uniform distortion can be produced, the requirement that the deflection of mounting edge upper and lower arc limit and both sides straight flange is different cannot be met.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of local bulging device of aero-engine high temperature alloy mounting edge, makes annular forging piece in Bulging Process, different distortion amount occurs between each section.
For solving the problems of the technologies described above, bulging device of the present invention, is made up of base, base fixture block, bulging block, core fixture block, mandrel slide block and guide rail; Mandrel slide block set is contained in the middle of bulging block and core fixture block, and coordinates with the plane that bulging block does certain angle of inclination; Mandrel slide block is lower mobile vertically by the effect of external force, and Extrusion bulging block is along guide rail to radial expansion, thus reaches the object of bulging; Wherein, described mandrel slide block can not be identical with the coupling angle of each bulging block.
Further, described mandrel slide block is 80 ° ~ 88 ° with the angle of mating of bulging block
Compared with prior art, beneficial effect of the present invention is as follows:
The local bulging device of aero-engine high temperature alloy mounting edge of the present invention, mate angle by what regulate mandrel slide block and bulging block, make annular forging piece after bulging, the deflection of its each several part is all not identical.This device is mainly for the manufacture of mounting edge, replace artificial open die forging pulling mode conventional at present to produce mounting edge, thus the different upper and lower arc limit of deflection can be obtained, improve the quality conformance of product, reliability, improve production efficiency, reduce raw materials consumption.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described:
As shown in Figure 1, a kind of local bulging device of aero-engine high temperature alloy mounting edge, is made up of base 1, base fixture block 2, bulging block 31 ~ 36, core fixture block 4, mandrel slide block 5 and guide rail 6; Mandrel slide block 5 is sleeved on the centre of bulging block 31 ~ 36 and core fixture block 4, and coordinates with the plane that bulging block 31 ~ 36 does certain angle of inclination; Mandrel slide block 5 is lower mobile vertically by the effect of external force, and Extrusion bulging block 31 ~ 36 is along guide rail 6 to radial expansion, thus reaches the object of bulging.
The main feature of this bulging device is, described mandrel slide block 5 can not be identical with the coupling angle of each bulging block 31 ~ 36, and as shown in Figure 2, mandrel slide block 5 is α with the matching angle of bulging block 32, is β with the matching angle of bulging block 35; In like manner, mandrel slide block 5 also can not be identical with the matching angle of bulging block 31, bulging block 33, bulging block 34, bulging block 36, but these matching angles are all between 80 ° ~ 88 °.
Fig. 3 ~ Fig. 5 is respectively the front view of mandrel slide block 5, left view and right view.I, II, III, IV, V, VI are mandrel slide blocks 5 and the contact surface of bulging block 31, bulging block 32, bulging block 33, bulging block 34, bulging block 35, bulging block 36 respectively.
The operation principle of this device is as follows:
Annular forging piece is loaded on the step of bulging block 31 ~ 36 of bulging device, and by base fixture block 2 and core fixture block 4 annular forging piece clamped and fix.Under the effect of external force F, promote mandrel slide block 5 lower mobile vertically, I, II, III, IV, V, VI face of mandrel slide block 5 promotes bulging block 31 ~ 36 respectively along guide rail 6 and makes radial expansion; Due to the angle of inclination in I, II, III, IV, V, VI face, namely mandrel slide block 5 and bulging block 31 ~ 36 to mate angle different, so bulging block 31 ~ 36 act under each section of annular forging piece between deflection also different.
