Abstract
The utility model discloses a forging die for forging a wheel core forging stock and capable of ensuring consistent centre lines of an upper die and a lower die. The forging die comprises the upper die and the lower die, which are provided with cavities matched with the wheel core forging stock respectively; the upper die is provided with an annular boss on the outer side of the edge mouth of the cavity of the upper die; the lower die is provided with an annular recess on the outer side of the edge mouth of the cavity of the lower die; the inner wall of the annular boss is provided with a conical upper guiding surface; and the inner wall of the annular recess is provided with a lower guiding surface matched with the upper guiding surface. Through the utility model, the lower guiding surface arranged on the outer side of the edge mouth of the cavity of the lower die can completely bear the horizontal force in the pressing process of the upper die so as to ensure consistent centre lines of the upper and lower dies and reliably guarantee the quality of the pressed forging stock.
Description
Technical field
The utility model relates to forging die, refers more particularly to the forging die that is used to forge the core wheel forging stock.
Background technology
Will weigh more than 600 kilogram core wheel blank compacting core wheel forging stock with the press that forging die is housed the time, guarantee upper and lower mould center line consistent be key point.For this reason, three leads of on the counterdie periphery, burn-oning, patrix is along the lead pressing when compacting, in the pressing process, blank can not remain vertical force usually and move downwards in deformation process, can produce the horizontal force that upper and lower mould is moved inevitably, because most of power all is delivered on the lead by patrix, therefore, when lead holds when can't stand this horizontal force, will be crooked, thus cause upper and lower mould to lose the guiding restriction, so just can't guarantee the correct centering of upper and lower mould, promptly upper and lower mould center line is inconsistent.Like this, the quality of the forging stock that compacting obtains just can not get guaranteeing, thereby causes waste product.
The utility model content
Technical problem to be solved in the utility model is: a kind of forging die that is used to forge the core wheel forging stock that can guarantee upper and lower mould center line unanimity is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the forging die that is used to forge the core wheel forging stock, comprise: the upper and lower mould that offers the die cavity that matches with the core wheel forging stock respectively, described patrix has annular boss in the arranged outside of its die cavity bead, described counterdie has ring-shaped depression in the arranged outside of its die cavity bead, the inwall of annular boss is provided with the last spigot surface of taper, and the inwall of ring-shaped depression is provided with the following spigot surface that matches with last spigot surface.
Offer the bore of the punch that communicates with its die cavity on the described patrix.
Described counterdie is provided with the positioning boss that matches with described bore of the punch in the bottom of its die cavity.
The beneficial effects of the utility model are: because the following spigot surface in the die cavity bead of the counterdie outside is enough to bear the biasing force that presses down the horizontal direction in the process from patrix, thereby it is fashionable in upper and lower mold pressing, can guarantee upper and lower mould center line unanimity, make that the quality of the forging stock that compacting obtains is reliably guaranteed.

Among Fig. 1 to Fig. 3: 1, patrix, 11, annular boss, 111, go up spigot surface, 112, the bottom surface, 12, bore of the punch, 2, counterdie, 21, ring-shaped depression, 211, spigot surface down, 212, platform, 22, positioning boss, 3, the core wheel forging stock.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, the forging die that is used to forge the core wheel forging stock described in the utility model, comprise: offer respectively the die cavity that matches with core wheel forging stock 3 on, counterdie 1 and 2, patrix 1 has annular boss 11 in the arranged outside of its die cavity bead, counterdie 2 has ring-shaped depression 21 in the arranged outside of its die cavity bead, the inwall of annular boss 11 is provided with the last spigot surface 111 of taper, the inwall of ring-shaped depression 21 is provided with the following spigot surface 211 that matches with last spigot surface 111, and, on, when counterdie 1 and 2 pressings, the bottom surface 112 of annular boss 11 just in time is resisted against on the platform 212 of ring-shaped depression 21; In the present embodiment, offer the bore of the punch 12 that communicates with its die cavity on the described patrix 1, described counterdie 2 is provided with the positioning boss 22 that matches with described bore of the punch 12 in the bottom of its die cavity.
Claims (3)
1. be used to forge the forging die of core wheel forging stock, comprise: the upper and lower mould that offers the die cavity that matches with the core wheel forging stock respectively, it is characterized in that: described patrix has annular boss in the arranged outside of its die cavity bead, described counterdie has ring-shaped depression in the arranged outside of its die cavity bead, the inwall of annular boss is provided with the last spigot surface of taper, and the inwall of ring-shaped depression is provided with the following spigot surface that matches with last spigot surface.
2. forging die as claimed in claim 1 is characterized in that: offer the bore of the punch that communicates with its die cavity on the described patrix.
3. forging die as claimed in claim 2 is characterized in that: described counterdie is provided with the positioning boss that matches with described bore of the punch in the bottom of its die cavity.
