Abstract
The utility model relates to a forging and pressing technical field specifically is a cross forging. It includes that a flat structure and symmetry set up flat structure's both sides protruding, cross forging's cross -section is the cross, the last levelling device that still sets up of cross forging. Put including cope match -plate pattern and lower bolster than the paper -back edition. The utility model discloses because technical scheme more than adopting, its advantage is: the utility model discloses cross forging allowance is little, and the tissue is even, and whole cross -section warp fully, grain refinement, shape rule, forging high quality.
Description
Technical field
The utility model relates to forging technology field, specifically a kind of cross-shaped forging piece.
Background technology
Need to design a kind of cross-shaped forging piece in ITER (International Thermal-Nuclear Experimental Reactor) project, he is used to the critical component of support magnet.Because its out-of-shape, length are longer, thinner thickness, so add the problem existing man-hour and be easy to be out of shape.
Utility model content
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of even tissue and the cross-shaped forging piece of easily smoothing.
For solving the problems of the technologies described above, a kind of cross-shaped forging piece of the present utility model, it projection of both sides comprising a slab construction and be symmetricly set on described slab construction, the cross section of described cross-shaped forging piece is cruciform, and described cross-shaped forging piece also arranges leveling apparatus.
Described cross-shaped forging piece is made by 316LN austenitic stainless steel.
Described comparatively leveling device comprises cope match-plate pattern and lower bolster.
The utility model is owing to adopting above technical scheme, and its advantage is: the utility model cross-shaped forging piece process redundancy is little, even tissue, and whole section deformation is abundant, and grain refinement, regular shape, forging quality is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cross-shaped forging piece;
Fig. 2 is the smoothing view of the utility model cross-shaped forging piece.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As Figure 1-Figure 2, a kind of cross-shaped forging piece of the present utility model, it projection 2 of both sides comprising a slab construction 1 and be symmetricly set on described slab construction 1, the cross section of described cross-shaped forging piece is cruciform, and described cross-shaped forging piece also arranges leveling apparatus 3.
Described cross-shaped forging piece is made by 316LN austenitic stainless steel.
Described comparatively leveling device comprises cope match-plate pattern 31 and lower bolster 32.
The forming method of cross-shaped forging piece, comprises the following steps:
1) a set of mould shaping for upsetting squeeze comprising lower seal, lower gasket, the first external mold, core rod and upper gasket is manufactured, wherein, external mold and core rod are all ringwise, it is the first trapezoidal groove that the inwall of external mold and the outer wall of core rod all arrange a ring cross-section, and the top of lower seal is provided with an annular groove;
2) blank that alloy pig is processed into annular is got;
3) lower seal is put on the table, lower gasket is put into the annular groove of lower seal, external mold is held in place the top of the lower seal outside lower gasket, core rod is held in place the top of the lower seal inside lower gasket;
4) blank is put into the ring cavity between the external mold of mould and core rod, again upper gasket is placed on blank, utilize hydropress by upper gasket to pressing down, then stop solution press, by die flip 180 °, take off lower seal, lower gasket to pressing down, is obtained cruciform loop base by recycling hydropress after hydropress upsetting squeeze processing;
5) manufacture second external mold being used for rolling ring processing and an internal mold, the second external mold and internal mold are loop configuration, and it is the second trapezoidal groove that the outer wall of the second external mold and internal mold all arranges a ring cross-section;
6) the second external mold is nested with on the king roller of ring rolls, be nested with by internal mold on the core roller of ring rolls, open ring rolls, the second external mold, internal mold rotate respectively under the drive of king roller, core roller, rolling ring rolling is carried out to cruciform loop base, after processing, obtains cruciform ring;
7) cruciform ring cut open along short transverse, with the endoporus of plug through cruciform ring, hydraulic control machine presses down, and through the multiple rotary of plug, gradually cruciform ring is launched into cross-shaped forging piece;
8) between upper die and lower die cross-shaped forging piece being placed on levelling machine, it is the 3rd trapezoidal groove that the bottom surface of patrix and the end face of counterdie are respectively arranged with a cross section, start levelling machine, through to cross-shaped forging piece repeatedly smoothing in the longitudinal direction, finally to obtain in tabular and symmetria bilateralis arranges bossed cross-shaped forging piece.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Claims (3)
