Abstract

The invention relates to a heading extruding and forming method for an internal T-shaped ring part blank. The heading extruding and forming method includes the following steps that a raw material steel ingot is heated, and then blanks of a lower sealing ring, a lower gasket, an outer die sleeve, a die core and an upper gasket are manufactured respectively through a forging technology; annealing is conducted on the blanks; machining is conducted on the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket, and the margins of the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket are removed; afterwards, quenching and tempering are conducted, so that the rigidity of the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket reaches the 35-40 Rockwell hardness number; afterwards, assembling is conducted; the lower sealing ring is put on a work platform, then the lower gasket is put in a clamping groove of the lower sealing ring, and under positioning and guiding of the lower gasket, the outer die sleeve and the die core are put on the lower sealing ring; then the forge piece blank is placed, and the upper gasket is put on the blank; and a hydraulic machine is started. According to the heading extruding and forming method, the forge piece blank can be promoted to be formed to become a component with an internal T-shaped structure, and a foundation is provided for final ring rolling of an inner T-shaped ring part.

Description

Interior T-shaped ring blank upsetting squeeze forming method
Technical field
The present invention relates to a kind of interior T-shaped ring blank upsetting squeeze forming method, belong to forging technology field.
Background technology
Have the large-scale interior T-shaped ring of a kind of SB564UNSN06690 nickel base superalloy, as shown in Figure 1, this interior T-shaped ring 10 comprises a loop configuration to its structure, and the inwall of loop configuration is provided with a circle to radially-protruding projection, the cross section of this projection is T-shaped.This interior T-shaped ring is due to out-of-shape, the reason such as material deformation temperature range is narrow, material deformation drag is large, be difficult to direct looping mill rolling shaping, therefore, need the preformed first carrying out blank, namely first T-shapedly to create interior, then it is shaping to carry out looping mill rolling with looping mill.But, in prior art, also do not develop the preformed manufacture method of blank of sening as an envoy to.
Summary of the invention
For above-mentioned weak point of the prior art, the present invention aims to provide a kind of interior T-shaped ring blank upsetting squeeze forming method.
For solving the problems of the technologies described above, technical scheme of the present invention is: T-shaped ring blank upsetting squeeze forming method in a kind of, comprise the following steps: 1) T-shaped ring blank upsetting squeeze mould in processing, by its raw material Heating Steel Ingots to 1180 ~ 1200 DEG C, then produced the blank of lower seal, lower gasket, outer die casing, core rod and upper gasket respectively by Forging Technology; 2) blank of lower seal, lower gasket, outer die casing, core rod and upper gasket is carried out annealing in process; 3) machining is carried out to lower seal, lower gasket, outer die casing, core rod and upper gasket, remove respective unnecessary amount; 4) Quench and temper process is carried out to lower seal, lower gasket, outer die casing, core rod and upper gasket, make its hardness reach 35 ~ 40 Rockwell hardness numbers; Drilling operation is carried out to core rod, on the inwall of core rod, namely evenly gets out the steam vent that multiple groove T-shaped with cross section is communicated with; 5) lower seal, lower gasket, outer die casing, core rod and upper gasket are assembled; 6) lower seal is placed on workbench, afterwards lower gasket is put in the draw-in groove of lower seal, under the location of lower gasket and guiding, outer die casing and core rod are placed in lower seal; 7) place forge piece blank reheating subsequently, finally upper gasket is placed on blank; 8) primer fluid press.
The present invention is owing to adopting above technical scheme, and beneficial effect is: upsetting squeeze forming method proposed by the invention can impel forge piece blank reheating shaping, becomes the component with interior T-type structure, for final looping mill rolling becomes interior T-shaped ring to provide the foundation.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of interior T-shaped ring;
Fig. 2 is the cross-sectional schematic of interior T-shaped ring blank upsetting squeeze mould;
Fig. 3 is the cross-sectional schematic of interior T-shaped ring blank upsetting squeeze mould core rod.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, present invention is described.
As shown in Fig. 2-Fig. 3, T-shaped ring blank upsetting squeeze forming method in the present invention, comprises the following steps:
1) T-shaped ring blank upsetting squeeze mould in processing, by its raw material Heating Steel Ingots to 1180 ~ 1200 DEG C, then produces the blank of lower seal 1, lower gasket 3, outer die casing 4, core rod 5 and upper gasket 7 respectively by Forging Technology;
2) blank of lower seal 1, lower gasket 3, outer die casing 4, core rod 5 and upper gasket 7 is carried out annealing in process;
3) machining is carried out to lower seal 1, lower gasket 3, outer die casing 4, core rod 5 and upper gasket 7, remove respective unnecessary amount;
4) Quench and temper process is carried out to lower seal 1, lower gasket 3, outer die casing 4, core rod 5 and upper gasket 7, make its hardness reach 35 ~ 40 Rockwell hardness numbers; Drilling operation is carried out to core rod, on the inwall of core rod, namely evenly gets out the steam vent that multiple groove T-shaped with cross section is communicated with.
5) lower seal 1, lower gasket 3, outer die casing 4, core rod 5 and upper gasket 7 are assembled.
6) lower seal 1 is placed on workbench, afterwards lower gasket 3 is put in the draw-in groove of lower seal 1, under the location of lower gasket 3 and guiding, outer die casing 4 and core rod 5 are placed in lower seal 1;
7) place forge piece blank reheating, afterwards upper gasket 7 is placed on blank;
8) primer fluid press.
Lower seal 1 designs an annular groove, lower gasket 3 is put in lower seal 1 draw-in groove, lower gasket 3 simultaneously can to outer die casing 4, the effect of location and guiding is played in the placement of core rod 5, in order to make the easier filling die cavity of blank, make between blank and mould seamless, according to law of minimum resistance, material flows in core rod 5 die cavity, meanwhile, the die cavity of blank and core rod 5 is confined spaces, constitute vacuum state, opposite effect power is had to material flowing, unfavorable to blank material flowing on the contrary, in order to solve this conflicting problem, the invention in core rod 5 die cavity, devise 10-15 steam vent, destroy the vacuum state of die cavity, material is more prone to toward die cavity flowing.
Obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
