The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the connecting rod forging mold of the present embodiment is described in further detail.
As shown in Figure 1, its con-rod only two ends are provided with installing hole to the automobile connecting bar that the forging mold of the present embodiment will be processed.The mode of this connecting rod of processing mainly comprises strand processing and forging stock processing at present, and the connecting rod strength of its strand processing is lower, and service life is shorter; In forging stock process, installing hole is processed by follow-up drilling operating conventionally, and its processing technology is more complicated.
The present embodiment provides a kind of connecting rod forging mold,, it comprises Preform Die and finish-forging die.Its Preform Die as shown in Figure 2 and Figure 3, comprises die holder 1 and punch die 2, and die holder 1 is oppositely arranged up and down with punch die 2.Described die holder 1 is provided with die 3, and shape and the connecting rod of its die 3 adapt.At the two ends of its die 3, be provided with upwardly extending drift 4, for the installing hole at punch process connecting rod two ends.On its punch die, be provided with the punch corresponding with die 3 21, and on punch 21, the position corresponding with drift 4 is provided with depression 22 upwards.The effect of Preform Die is the preliminary base substrate of connecting rod rough forging, and the installing hole at punching press connecting rod two ends.
In order to be convenient for changing drift 4, its drift 4 is bolted and is arranged on drift fastening base 41, and drift fastening base 41 is fixedly connected with die holder 1 by bolt.
Further, its punch die 2 is provided with the guide pillar 23 to downward-extension, and on die holder 1, is provided with the fairlead 24 matching with guide pillar 23, in the process of punch die 2 undershoots, for locating stamping position.
After blocking machines, in order easily pre-forging to be taken out in die 3, the Preform Die in the present embodiment is also provided with backform device 42.It is located at the bottom of die 3, and in the vertical direction can move relative to die holder 1, and its effect is that the pre-forging in die is ejected.A preferred mode, its backform device 42 is sheathed on drift fastening base 41, and the ejecting force that is is more even.And in the present embodiment, backform device 42 is connected with die holder 1 by screw, when needs eject pre-forging, only needs rotary screw.
