The pre-stress processing mould is characterized in that the mould is composed of an upper mould, a middle mould, a lower mould and a plurality of accessories, wherein external threads A are arranged on the upper part of the upper mould, a recess B is formed in the lower part of the upper mould, and the recess B takes on a shape of wide upper part and narrow lower part; a deep groove E with one sealed end is formed in the middle mould, a recess D is formed in the outside of the middle mould, and the aperture of the recess D is matched with the recess B of the upper mould; one external thread G is arranged on the upper part of the lower mould, a through groove H is formed in the middle part of the lower mould, and the width of the through groove H is matched with the thickness of the middle mould; the width of a pad in each accessory is matched with that of the deep groove E of the middle mould; and the width of a pressing pad in each accessory is matched with that of the pad. The invention aims at providing a detachable mould with high high-temperature strength, economical efficiency and operation convenience.
Description
Technical field: the stress in advance that the present invention relates to a kind of superalloy field is processed mould.
Background technology: superalloy is widely used in the turbine disk and the blade material of aircraft engine, in process, creep impairment is its main failure mode under arms.The macro-mechanical property of superalloy and its heterogeneous microstructure are closely related, and alloy its weave construction in creep process can develop.If utilize the microstructure Evolution rule occurring during single crystal super alloy creep, adopt high temperature autofrettage, make γ ' in the alloy a certain orientation transition of handing down become raft shape tissue, to hinder dislocation motion, and increase substantially high-temperature mechanics and the creep property of alloy.
For many years, a lot of scholars are attempting employing autofrettage, the weave construction of alloy are changed, to putting forward heavy alloyed high-temperature mechanics and creep property.Yet, practice shows, the mould that stress is processed in advance has material impact to pretreated effect, especially to the larger sample of stress processing area in advance, need mould to have higher hot strength, meanwhile, the mould that stress is processed in advance also will be considered economy, ease-to-operate and detachability etc.For this reason, the superalloy stress processing in advance mould that we have designed in a kind of novel be directly installed on tensile test machine, can repeatedly dismantle.
Summary of the invention:
Goal of the invention: superalloy of the present invention in advance stress is processed mould, and its object is to provide a kind of mould with higher hot strength, economy, ease-to-operate and detachability.
Technical scheme: the present invention implements by the following technical programs:
Stress is processed a mould in advance, it is characterized in that: this mould by patrix, in mould, counterdie and some accessories thereof form, the top of patrix is provided with outside screw A, the fluted B of bottom band, groove B is shaped as shape wide at the top and narrow at the bottom; The inside of middle mould is with the deep trouth E of one end sealing, and outside with a groove D, the groove B of the bore of groove D and patrix matches; Counterdie top is provided with an outside screw G, and the middle part of counterdie is a groove H, and the width of groove H and middle mould gauge match; In accessory, the deep trouth E of the width of liner and middle mould matches; In accessory, the width of pressure pad and liner match.
The opening part side of the being provided with platform C of middle Molded Depth groove E; In accessory, also comprise the first supporting pad, the square platform C of the size of the first supporting pad and middle mould matches.
In accessory, also comprise the second supporting pad, the groove H of the size of the second supporting pad and counterdie matches.
Advantage and effect: mould provided by the present invention is the larger sample of stress processing area in advance, has higher hot strength, and can be directly installed in tensile test machine, can repeatedly dismantle, so easy and simple to handle, economical and practical.

Embodiment:
Below in conjunction with specific embodiment, the present invention is specifically described:
A kind of superalloy of the present invention in advance stress is processed mould, mainly by patrix 1, in mould 2, counterdie 3 and some accessories thereof form, concrete operations are: the F place that first liner shown in Fig. 44 is positioned over to mould 2 in Fig. 2, then the material base that stress is processed is in advance positioned over to the J place of Fig. 4, the pressure pad shown in Fig. 55 is pressed in to stress in advance and processes on material base product; Through in the deep trouth E of middle mould 2, counterdie I place is pressed on the pressure pad 5 on material base the counterdie shown in Fig. 33, the patrix 1 of Fig. 1 designs feature most, which is provided with groove B, and groove B is shaped as shape wide at the top and narrow at the bottom, matches with the groove D of middle mould 2; Finally the groove D of the groove B of patrix shown in Fig. 11 and middle mould 2 is plugged in together, whole mould installs.
The first supporting pad 6 shown in Fig. 6 is arranged on the square platform C place of mould 2 in Fig. 2, and it is played a supportive role, and prevents the distortion of middle mould 2.The second supporting pad 7 shown in Fig. 7 is arranged on to the counterdie H place being enclosed within middle mould, to prevent the distortion of counterdie 3.
Internal thread according to high temperature pull bar in creep testing machine, is provided with outside screw A at upper mould 1, and it is connected with the upper connecting rod of creep machine; At lower mould 3, be provided with outside screw G, and it is connected with the lower link of creep machine.
According to required load and temperature, utilize creep machine to load, realize the function that stress is processed in advance.
This mould is used directionally solidified superalloy, DS superalloy DZ002 casting to form, and is columnar crystal structure.Mould adopts the reasonable disposition of upper, middle, and lower part, and the tensile stress of creep testing machine is changed into stress; Upper and lower two molds retain screw position when casting, have cast and thermal treatment post-treatment screw thread, can make it be directly installed on tensile test machine.
