Description
Technical field
The utility model relates to technical field of forging, relates in particular to a kind of accessory-a kind of for forging the closed die of multidiameter bar of forging.
Background technology
What in prior art, forge the employing of multidiameter bar is open die forging, generally need through heating-jumping-up-pressure side-die forging-trimming-several main operations such as correction, the disadvantage of open die forging is wasted raw material exactly, needs the equipment personnel that drop into more, and production efficiency is low.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of closed molds, and operation only need to be passed through heating-die forging, and relatively open die forging, has saved 4 procedures, has reduced equipment personnel's input, has reduced raw-material waste.
The utility model is realized by the following technical solutions:
A kind of for forging the closed die of multidiameter bar, comprise counterdie (1), push rod (3), middle mould (4), patrix (7), described counterdie (1) is fixed on workbench by counterdie set bolt (2), described middle mould (4) is placed on by convex edge (43) in the middle mould putting hole (11) of counterdie (1), on middle mould (4), be also set with a pressing plate (5), pressing plate (5) is fixed on counterdie (1) by pressing plate fastening bolt (6), wherein, pressing plate fastening bolt (6) coordinates with pressing plate installing hole (10), described patrix (7) is placed on down on middle mould (4) in working order, patrix (7) working end coordinates with middle mould one-level hole (40).
As preferred version of the present utility model, the diameter of described convex edge (43) is identical with the internal diameter of middle mould putting hole (11).
As preferred version of the present utility model, in described counterdie (1), be also placed with push rod (3), push rod (3) is placed in push rod putting hole (12), and push rod (3) convex edge external diameter is identical with the internal diameter of push rod putting hole (12).
As preferred version of the present utility model, described pressing plate (5) is designed with pressing plate one-level hole (50), pressing plate second hole (51), and pressing plate one-level hole (50) internal diameter is identical with convex edge (43) external diameter.
The utility model compared with prior art has the following advantages and beneficial effect:
The utility model is by the push rod demoulding, and production efficiency is high, and equipment personnel less investment, for open forging, is saved raw material and reached more than 18%.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model mainly comprises counterdie (1), push rod (3), middle mould (4), patrix (7).
Counterdie (1) is fixed on workbench by counterdie set bolt (2), and middle mould (4) is placed in the middle mould putting hole (11) of counterdie (1) by convex edge (43).
On middle mould (4), be also set with a pressing plate (5), it is upper that pressing plate (5) is fastened on counterdie (1) by pressing plate fastening bolt (6), and wherein, pressing plate fastening bolt (6) coordinates with pressing plate installing hole (10).
It is upper that patrix (7) is placed on down middle mould (4) in working order, and patrix (7) working end coordinates with middle mould one-level hole (40).
For the ease of assembling, the diameter of convex edge (43) is identical with the internal diameter of middle mould putting hole (11).
For the ease of assembling, pressing plate (5) is designed with pressing plate one-level hole (50), pressing plate second hole (51), and pressing plate one-level hole (50) internal diameter is identical with convex edge (43) external diameter.
For the ease of realizing function described in the utility model, in counterdie (1), be also placed with push rod (3), push rod (3) is placed in push rod putting hole (12), and push rod (3) convex edge external diameter is identical with the internal diameter of push rod putting hole (12).
When work, the bar after heating is put into the mould one-level hole (40) of mould (4), patrix (7) starts to be pressed into, bar after heating is under the extruding of patrix (7), after plastic deformation, mould one-level hole (40) in formation, middle mould second hole (41), stepped axle shown in three grades of holes of middle mould (43), then lift patrix (7), manually promote push rod (3), push rod (3) working end enters three grades of holes of middle mould (43), jack-up multidiameter, the course of work finishes.
Certainly; those skilled in the art should be realized that, above-described embodiment is only for the utility model is described, not to restriction of the present utility model; as long as the conversion of making within the scope of connotation of the present utility model, modification all will be in claim protection domain of the present utility model.
