Compared with prior art, the utility model has the beneficial effects that the utility model is by designing special resistance material type
Slot realizes strength resistance material, and metal is forced to prolong preset direction flowing.Base and blocking can be integrated into a die cavity, simplify forging
Process is made, shortens and forges each work step time, especially suitable racemosus wooden fork forging, while can effectively solve small lot, multi items
Equipment, mold and the personnel's problem of forging, blank is attached to lower die after can also controlling forging, facilitates forging stock clamping transfer.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model schematic diagram of internal structure.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of hot forging strength resistance material type groove device, including
Upper mold 2 and lower die 7 are equipped with upper mold on the inside of the upper mold 2 and squeeze type groove 1, be equipped with lower die on the inside of the lower die 7 and squeeze type groove 6, institute
It states upper mold and squeezes type groove 1 and lower die extruding 6 face of type groove setting, also form resistance material type groove, institute between the upper mold 2 and lower die 7
It states resistance material type groove to be made of horizontal bridge portion 5, stairstepping high pressure resistance material type groove 4 and clout storehouse portion 3, the stairstepping high pressure resistance material
Type groove 4 is horizontal by 70 ° of angles.Coupled on the outside of stairstepping high pressure resistance material type groove is clout storehouse portion, for holding
Receive excess metal, storehouse portion height usually takes 15-20mm.
In the utility model, 5 height 8-10mm of horizontal bridge portion, width 30mm, 5 inside of horizontal bridge portion and die cavity phase
Even, rounded corner R3-R5,5 outside of horizontal bridge portion are connected with stairstepping high pressure resistance material type groove 4, connecting portion fillet R3-
R5。
In the utility model, lower die 7 is made of three stairsteppings, and each ladder height is selected according to round billet gauge lattice used
Fixed, each ladder vertical plane does 1.5 ° of pattern draft, and general blank diameter 100-150mm is 16mm by each ladder height,
Blank diameter 160-200mm is 20mm, the resistance material ladder boss to 70 ° of plane minimums of upper mold by each ladder height
Bridge portion height 3.5-4mm.Since the gradient is smaller, blank can be attached to lower die after blocking.Blank after forging is facilitated to eject and shift.
70 ° of angles add stepped designs, considerably increase the resistance that metal stock flows outward in die cavity, force metal material to prolong pre-
If die cavity extends, achieve the purpose that strength squeezes.
Working principle: when tup sliding block is located at stroke upper end, upper mold 2 and lower die 7 are in the open state, and blank is put into
Lower die squeezes in type groove 6, with the positioning of type groove circular arc.Strike stroke starts rear upper mold extruding type groove curved bottom and contacts base first
Material, forces blank to horizontal and vertical extension, and when blank lateral flow to horizontal bridge portion, lateral flow resistance is increased, and inclines
After the contact of sloping step resistance material slot, clout flow direction is turned back 70 ° of angles, and resistance increases again, is entered with upper mold strike downlink blank
Resistance material type groove is tilted, and the thickness for tilting resistance material slot is smaller and smaller, tilts the stepped designs (see figure 2) of resistance material slot in addition, resistance
Material power sharply increases, and longitudinal type groove is made into circular conical surface along metal direction and reduces flow resistance (see figure 1), and metal is made to do more longitudinal directions
Flowing reaches anticipation distribution material purpose.Each ladder vertical plane does 1.5 ° of pattern draft (see figure 2), since angle is smaller,
The adhesive force (gradient of upper mold is 20 °) that forging stock can be increased, so that forging is attached to lower die always, facilitates depanning and movement.
This extruding type groove is combined together with blocker, it is convenient to omit is fallen special pulling process, is shortened process flow, operation more saves
Power, it is simple and easy.
In conclusion the utility model realizes strength resistance material, forces metal to prolong default by designing special resistance material type groove
Direction flowing.Base and blocking can be integrated into a die cavity, simplify forging process, shorten and forge each work step time, especially
It is applicable in racemosus wooden fork forging, while can effectively solve small lot, equipment, mold and the personnel's problem of multi items forging may be used also
It is attached to lower die with blank after control forging, facilitates forging stock clamping transfer.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
