Abstract

The invention relates to an upset-extruding mold for a special-shaped ring piece blank. The upset-extruding mold comprises a lower sealing ring; an annular groove is formed in the top part of the lower sealing ring; a lower gasket is arranged in the groove; and an annular outer film sleeve is arranged on the top part of the lower sealing ring on the outer side of the lower gasket; a mould core is arranged on the top part of the lower sealing ring on the inner side of the lower gasket; the mould core is of an annular structure with a thickness; a circle of groove with a T-shaped cross section is formed in the outer wall of the annular structure; and multiple vent holes which are communicated with the groove with the T-shaped cross section are uniformly formed in the inner wall of the mould core. The upset-extruding mold has the following advantages: 1, by adopting the upset-extruding mold disclosed by the invention, the forge piece blank can be molded into a component of an inner-T-shaped structure, and a basis is provided for finally ring-rolling a ring piece with an inner-T-shaped structure; and 2, the upset-extruding mold is simple in structure, low in cost and easy for promotion.

Description

The mould that the upsetting squeeze of abnormity ring blank is shaping
Technical field
The present invention relates to the mould that the upsetting squeeze of a kind of special-shaped ring blank is shaping, 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 mould 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 shaping mould of a kind of special-shaped ring blank upsetting squeeze and preparation method thereof.
For solving the problems of the technologies described above, technical scheme of the present invention is: the mould that the upsetting squeeze of a kind of special-shaped ring blank is shaping, it is characterized in that: it comprises a lower seal, the groove of one annular is set at the top of described lower seal, a lower gasket is placed in described groove, a ringwise outer Membrane cover is placed at the top being positioned at the described lower seal outside described lower gasket, a core rod is placed at the top being positioned at the described lower seal inside described lower gasket, described core rod is one with the loop configuration of thickness, the T-shaped groove of a ring cross-section is offered at the outer wall of described loop configuration, the inwall of described core rod evenly offers the steam vent that multiple described groove T-shaped with cross section is communicated with.
Also comprise a upper gasket, described upper gasket is positioned over the top of described blank after forge piece blank reheating is placed in the ring cavity that described outer die casing and described core rod surround, and between described outer die casing and described core rod.
The present invention is owing to adopting above technical scheme, and it has the following advantages: upsetting squeeze mould 1, 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.2, structure of the present invention is simple, with low cost, is easy to promote.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The present invention proposes the mould that the upsetting squeeze of a kind of special-shaped ring blank is shaping, as figures 2-6, it comprises a lower seal 1, the groove 2 of one annular is set at the top of lower seal 1, a lower gasket 3 is placed in groove 2, a ringwise outer Membrane cover 4 is placed at the top of the lower seal 1 be positioned at outside lower gasket 3, a core rod 5 is placed at the top of the lower seal 1 be positioned at inside lower gasket 3, core rod 5 is one with the loop configuration of thickness, the T-shaped groove of a ring cross-section 6 is offered at the outer wall of loop configuration, the inwall of described core rod 5 evenly offers the steam vent 9 that multiple described groove 6 T-shaped with cross section is communicated with.Carrying out in the process of upsetting squeeze to forge piece blank reheating 8, material flows in the groove 6 of core rod 5 according to law of minimum resistance, if do not arrange steam vent 9, it will be a confined space between forge piece blank reheating and core rod 5, the existence of the air that the inside is sealed up for safekeeping is unfavorable for the flowing of material, the inwall of core rod 5 arranges the steam vent 9 be communicated with groove 6 and then can solve this contradiction.
In a preferred embodiment, also comprise a upper gasket 7, after forge piece blank reheating 8 is placed in the ring cavity that outer die casing 4 and core rod 5 surround, upper gasket 7 is positioned over the top of forge piece blank reheating 8, and between outer die casing 4 and core rod 5.Now, primer fluid press just can complete the upsetting squeeze of forge piece blank reheating 8 shaping.
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.
