The bottom mould includes a rotary module and a shaping part, the rotary module is arranged on two ends of the shaping part and is hinged with a connection part; the rotary module and the shaping part are collapsible. The mould of the utility model is capable of reducing possibility of producing a sharp angle of the shaft-like forgings, protecting the mould and reducing materials.
Description
Technical field
The utility model relates to a kind of mould that is used to forge forged shaft, particularly relates in a kind of forging and is used for the mould that forged shaft falls round usefulness.
Background technology
In the Forging Technology,, generally all utilize shaping mould (tup) that forged shaft is fallen round roughing earlier now to the forging of axle class.It is exactly when forging the forging of axle class that what is called is fallen round Forging Technology, on the forging machine it is carried out preliminary shaping processing; Add man-hour, forging is placed between upper and lower two moulds (upper and lower tup), bed die (following tup) maintains static, in order to support forging, mold (going up tup) is under the effect of the machine of forging, forging is done the impact of circulation, under impact force action, the fit circular shape of upper and lower mould (upper and lower tup) shaping unit of forged shaft, forged shaft rotates or rotates with fixed angle during forging, to realize the shaping of forged shaft circular cross-section, fall circle so cry, the mould that corresponding forging is used is called tup.
Existingly be used to fall round shaping mould (tup) and generally form (as accompanying drawing 1, shown in Figure 2) by mold (go up tup), following two ones (following tup) part, as previously mentioned, when falling the circle forging, bed die (following tup) maintains static, in up-and-down motion, forged shaft is applied the impulsive force of circulation by mold (going up tup).Can see, after mould (upper and lower tup) closure up and down, it is inner also not exclusively to be circular, but in the part of mould (upper and lower tup) contact up and down, the circular arc of the interior shaping of mould (upper and lower tup) portion all is to plane that mould (upper and lower tup) up and down is in contact with one another by round-corner transition up and down, its purpose is wedge angle (as accompanying drawing 3, shown in Figure 4) the damage forging in order to prevent that circular arc from forming to contact plane.
But; when in fact forged shaft being fallen circle and forges, especially, during to the bigger forged shaft of diameter; occur through regular meeting; in the part of mould (upper and lower tup) contact up and down, forged shaft forms wedge angle under upper and lower mould (upper and lower tup) impact extruded; behind the one-shot end cycle; forged shaft will rotate, and the wedge angle of formation can damage mould or rupture under impacting and break away from forged shaft, thereby causes mould damage or loss of material.
The utility model content
The technical problem that the utility model solved is to provide a kind of and falls bowlder at the forging forged shaft, the removable mold that is used to forge forged shaft of wedge angle do not occur.
The technical solution that realizes the utility model purpose is: a kind of forged shaft that is used for falls the round detachable mould that contains rotating module, comprise mold and bed die, mold comprises rotating module and shaping portion, and rotating module is arranged on the two ends of shaping portion, and the portion of being connected through the hinge connects; Described rotating module and shaping portion are detachable.
The utility model compared with prior art, its remarkable advantage: reduced the possibility that forged shaft produces wedge angle, protected mould, saved material.
Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment
In conjunction with Fig. 5, Fig. 6, a kind of forged shaft that is used for of the present utility model falls the round detachable mould that contains rotating module, comprises mold 1 and bed die 2, and mold 1 comprises rotating module 4 and shaping portion 3, rotating module 4 is arranged on the two ends of shaping portion 3, and the portion 10 that is connected through the hinge connects; Described rotating module 4 and shaping portion 3 are detachable.Bed die 2 comprises rotating module 4 and shaping portion 3, and rotating module 4 is arranged on the two ends of shaping portion 3, and the portion 10 that is connected through the hinge connects; Described rotating module 4 and shaping portion 3 are detachable.Contact-making surface between shaping portion 3 and the rotating module 4 is a circular arc.Rotating module 4 is provided with contact fillet surface 7, and this curved surface is the contact-making surface between shaping portion 3 and the rotating module 4.
Shaping portion 3 is provided with shaping portion circular arc camber 5, (falls circle) and mainly lean on this part to forged shaft shaping (falling circle) when forging, and shaping portion circular arc camber 5 circular arc cambers connect the front/rear end of shaping portions 3 by end face fillet surface 11; Rotating module 4 is provided with contact plane 6, contact fillet surface 7, outer surface 9, front end face, rear end face and rotation compensation curved surface 8, the front/rear end of rotating module 4 aligns with the front/rear end of described shaping portion 3, the contact plane 6 of rotating module 4 with contact fillet surface 7 by being connected to described rotating module 4 front/rear ends with the identical curved surface of the end face fillet surface 11 of shaping portion 3.When rotating module 4 does not rotate, the contact plane 6 of rotating module contacts with the bed die contact plane, the contact fillet surface 7 of rotating module is connected with shaping portion circular arc plane 5, be linked to be a unified curved surface, rotation compensation curved surface 8 when rotating module rotates and the circular arc camber of shaping portion be linked to be a level and smooth curved surface.
Described shaping portion and rotating module also are to be in the hinge that closed elasticity recovers when making rotating module not be subjected to external force to be connected.It can be to be in the hinge that closed elasticity recovers when making rotating module not be subjected to external force to connect that the rotating module of described mold is connected with the hinge of described shaping portion.
When rotating module does not rotate, the contact plane of described rotating module contacts with the bed die contact plane, the contact fillet plane of described rotating module is connected with the circular arc plane of described shaping portion, be linked to be a unified curved surface, described rotation compensation curved surface when described rotating module rotates and the circular arc camber of described shaping portion be linked to be a level and smooth curved surface.
As shown in Figure 7, because forging the sired results of falling of forged shaft plants, mainly finish by 1 pair of forging repeated stock of mold, so the utility model is an embodiment wherein, only adopt above-mentioned structure at upper module, do not possess under the function of elastic recovery in the hinge connection, also can pass through gravity, rotating module 4 be remained closed in uphill process at mold 1, and when the forging of whereabouts, rotate according to forging.
Another embodiment of the present utility model is, on a last embodiment basis, adopts the hinge of elastic recovery to connect, and flexible size is decided according to the forging concrete condition.
The 3rd embodiment of the present utility model as shown in Figure 5, mold 1 and bed die 2 all adopt the structure of above-mentioned rotating module 4 and shaping portion 3, and adopt the hinge of elastic recovery to connect, flexible size is decided according to the forging concrete condition.
The material of the foregoing description can be a carbide alloy, as 5CrMnMo.
Above embodiment all can reach the requirement when forging forged shaft, when running into the bigger raw material of diameter tolerance, the original position that forms wedge angle easily of both mold ends, when running into big load, contact-making surface can be made a concession from the trend both sides, thereby reduces the possibility that forms wedge angle.
