Description

The aero-engine manufacturing process of high temperature alloy mounting edge

Technical field

The present invention relates to a kind of manufacturing process of mounting edge, particularly relate to a kind of manufacturing process 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, shaping difficulty 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.

Disclosed in 5 days Mays in 2010, Chinese invention patent description CN101700557A discloses a kind of mounting edge vertical forging and forming technology, its basic craft course is: blanking → jumping-up → punching → reaming → head-stamp → monolateral elongation → button angle → shaping → school shape, its whole process is mainly carried out on flat-die hammer, and the vertical forging achieving mounting edge is shaped.But adopt when producing mounting edge in this way, due to the difference of mounting edge cross section and arc length, when carrying out flat-die hammer pulling to the upper and lower segmental arc of mounting edge, be difficult to precisely control; And the method needs surplus very large, not easily beats and leans on; Owing to needing the artificial subjective size controlling mounting edge, its precision can not get effective control; And stock utilization is very low.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of manufacturing process of aero-engine high temperature alloy mounting edge, by the forming mode adopting looping mill rolling to combine with bulging, effectively can control the size of mounting edge, obtain the mounting edge meeting tissue, performance and dimensional requirement, and improve stock utilization.

For solving the problems of the technologies described above, the manufacturing process of aero-engine high temperature alloy mounting edge of the present invention, its technical scheme comprises the following steps:

High temperature alloy by specification blanking is heated to deformation temperature, after jumping-up jumping-up, punching, is rolled into ring base;

Described ring base is divided, head-stamp, described ring base is divided into ab, bc, cd, ad tetra-sections, and wherein, the arc chord angle corresponding to ab section is 128 DEG C, and the arc chord angle corresponding to cd section is 114 DEG C, and ad section and the arc chord angle corresponding to bc section are respectively 59 DEG C;

Ring base good for described head-stamp being heated to bulging temperature loads on the bulging device of local, and this device is by base, two base fixture blocks, 3 front bulging blocks, bulging block, two core fixture blocks and mandrel slide block form after 3; Forward and backward bulging block is different from mandrel slider contact surface gradient, and its ratio is α: β=2:3; Drive the core fixture block on the bulging device of local and base fixture block that the ad section of ring base and bc section are clamped and fixed; Mandrel slide block is driven to move down, and promote front bulging block, rear bulging block and respectively bulging is carried out to the ab section of ring base and cd section, in Bulging Process, by cooling water pipe to clamped ad section and bc section water-spraying control, to improve this resistance of deformation of two sections, make these the two sections shapes that substantially remain unchanged in Bulging Process; After bulging completes, obtain local bulging base;

Between upper and lower two metal baffle local bulging base being put into pre-expanding die former, and align with the pass of metal baffle, with fastening spring, local bulging base is fixed; Again the microcephaly of formpiston is inserted in the pass of pre-bulging former, from top to bottom, through local bulging base, and pre-bulging is carried out to it, obtain pre-bulging base;

Between upper and lower two metal baffle pre-bulging ring base being put into whole expanding die former, and align with the pass of metal baffle, then the microcephaly of formpiston is inserted in the pass of whole bulging former, from top to bottom, through pre-bulging base, and whole bulging is carried out to it, obtain mounting edge.

The formpiston of described pre-expanding die is a drift, and its shape is similar to the pass of mounting edge, and from top to bottom, its cross-sectional area reduces gradually; Former is made up of the metal baffle of upper and lower two-layer band pass and the rectangular metal contiguous block that connects them, and lower baffle plate has 4 for fastening spring, the pass of upper and lower baffle plate is all similar to the pass of mounting edge.

The formpiston of described whole expanding die is a drift, and its shape is similar to the pass of mounting edge, and from top to bottom, its cross-sectional area reduces gradually; Former is made up of the metal baffle of upper and lower two-layer band pass and the rectangular metal contiguous block that connects them, lower baffle plate there are 4 for fastening spring, the pass of upper and lower baffle plate is all similar to the pass of mounting edge, and the limit shape of metal contiguous block is consistent with the lower arc limit of mounting edge.

Compared with prior art, beneficial effect of the present invention is as follows:

The manufacturing process of aero-engine high temperature alloy mounting edge of the present invention, the forming mode adopting looping mill rolling to combine with bulging instead of free forging mode, improve the quality conformance of product, reliability, improve production efficiency, reduce raw materials consumption.For the shaped as frame that changes of section is larger, adopt local bulging to reduce sectional area, the open die forging pulling mode before instead of, this process is easy to control.Local bulging adopts water-cooling pattern, increases the resistance of deformation of this position after making the Local cooling of ring base, ensure that two arc limits are indeformable or only produce small deformation in Bulging Process.On the other hand, local expanding die adopts bielliptic(al) structure, because front bulging block is different from the gradient of rear bulging block, is out of shape different bielliptic(al) blanks.The former of pre-bulging device and whole bulging device all adopts double-decker, and formpiston can be facilitated to extract, and can prevent blank from Bulging Process, the defects such as warpage occurring.
