Domain.
Background technology
Forging and molding refers to applying external force to metal, so that metal is generated plastic deformation, changes the shape and size of blank, change
It is apt to its interior tissue and mechanical property, obtains definite shape, size and the blank of performance or the forming and machining method of part.
Fork-shaped forging is generally made of forked head and bar portion, and in most cases, this forging needs during blocking
To use cleaver divider that blank end from center point to both sides, is forged fork-shaped.Traditional fork-shaped forging Preform Die is:In its mould
At the die joint for having upper and lower mould, the overlap that upper and lower mould, the bridge portion of certain altitude and storehouse portion are constituted is set along mold impression periphery
Slot makes upper and lower mold have gap and neutral gear.Mold metal extra when being closed can be expelled to neutral gear by gap (bridge portion)
(storehouse portion) forms overlap, it, which can generate resistance, makes metal full of impression to complete a forging and molding.But this form is winged
The restricting resistance force of metal of the side slot structure to being flowed along forked head length and width direction is consistent, due to forked head length compared with
Long, along the metal of forked head width direction flowing, often premature discharge impression flows to overlap storehouse, fork impression in impression
The most deep place in bottom is not easy to be full of metal, and the defect of depths underfill occurs in fork-shaped forging when finish-forging being caused to shape.
Utility model content
In view of the above technical problems, the utility model provides a kind of Preform Die of fork-shaped forging, to increase fork-shaped forging
Along the resistance of the metal of forked head width direction flowing when forging, metal is made to be easy to be full of impression.
For the above technical purpose of realization, the technical solution of the utility model is：
A kind of Preform Die of fork-shaped forging, including upper die and lower die are provided with impression in upper mold, are provided in lower die
Lower impression, upper impression and lower impression are encircled into mold impression, and impression includes forked head, and forked head front end center outwardly protrudes
Cleaver divider is formed, impression periphery is provided with flash gutters, and flash gutters include overlap bridge and overlap storehouse, and the setting of overlap bridge is in impression and flies
Between the storehouse of side, which is characterized in that be provided with resistance ditch in overlap storehouse, resistance ditch is located in front of forked head, and and forked head
At 0~20 ° of angle, resistance ditch length is more than the width of cleaver divider.The utility model Preform Die is provided with resistance in overlap storehouse
Power ditch increases the flow resistance of the metal flowed along forked head width direction, and metal is made to be easy to be full of impression.
Preferably, the resistance ditch includes the first resistance ditch, and the first resistance ditch is with forked head front end at a distance of 8
~12mm, the first resistance ditch length are the 1/3~1/2 of forked head length.
As further preferred scheme, the resistance ditch further includes the second resistance ditch, the second resistance ditch and the first resistance ditch
It is arranged in parallel and at a distance of 17~22mm, the second resistance ditch length is the 50~70% of the first resistance ditch.
As further preferred scheme, the resistance ditch is set as cylindrical, a diameter of 6~12mm.
As further preferred scheme, pass through rounded corner transition, chamfer radius 6mm between the impression wall and overlap bridge
~14mm.The setting of chamfering can slow down mold wedge angle position heap and collapse problem, can also make gold extra on forging after blocker forging
Category is easier to be discharged to overlap storehouse, the case where avoiding folding at fork ear, improves die life.

Specific implementation mode
In conjunction with Fig. 1 to Fig. 3, a specific embodiment of the utility model is described in detail, but not to the power of the utility model
Profit requires to do any restriction.
As shown in Figure 1 to Figure 2, a kind of Preform Die of fork-shaped forging, including upper mold 1 and lower die 2 are provided in upper mold 1
Upper impression is provided with lower impression in lower die 2, and upper impression and lower impression are encircled into mold impression 3, and impression 3 includes forked head 8,
8 front end center of forked head outwardly protrudes to form cleaver divider 11, wherein the distance of 11 leftmost side of cleaver divider to the rightmost side is to split material
The width of platform 11,3 periphery of impression are provided with flash gutters, and flash gutters include overlap bridge 4 and overlap storehouse 5, and overlap bridge 4 is arranged in impression
Between 3 and overlap storehouse 5, the first resistance ditch 6 and the second resistance ditch 7 are set, the first resistance ditch 6 is located at forked head 8 in overlap storehouse 5
