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.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of forging mold of relatively large connecting rod, including
Upper mold 1 and lower die 2, setting blocking upper mold squeezes type groove 3 on the inside of the upper mold 1, and setting is squeezed with blocking upper mold on the inside of the lower die 2
The blocking lower die of 3 face of die mould slot setting squeezes type groove 4, and the blocking upper mold squeezes type groove 3 and blocking lower die squeezes in type groove 4
Between formed hot forging squeeze type groove, it is described hot forging squeeze type groove include extrusion die cavity 7 and ladder-type structure resistance material slot, the extruding
Die cavity is connected with the resistance material slot of ladder-type structure, and the hot forging squeezes type groove big end head for blocking die cavity, above and below small end head
Mould does not design the boss in blocking hole, in order to avoid influence the axial flowing of metal when bar portion squeezes.7 section of extrusion die cavity is ellipse
Structure, 7 sectional area of extrusion die cavity are 15-20% bigger than 8 sectional area of position finish-forging die cavity, squeeze out direction upper and lower mould along blank
2 ° of gradients are made, are gradually increased along direction section is squeezed out.
In the utility model, resistance material slot is made of horizontal bridge portion 5, stairstepping high pressure resistance material type groove 6 and clout storehouse portion 7,
The stairstepping high pressure resistance material type groove 6 is horizontal by 70 ° of angles；The 5 height 8-10mm of horizontal bridge portion, width 30mm, institute
It states 5 inside of horizontal bridge portion to be connected with die cavity, rounded corner R3-R5,5 outside of horizontal bridge portion and stairstepping high pressure resistance material type groove 6
It is connected, connecting portion fillet R3-R5；Lower die is made of three stairsteppings, and each ladder height is according to round billet gauge used
Lattice are selected, and general blank diameter 100-150 is 16 by each ladder height, and blank diameter 160-200 is by each ladder height
20, each ladder vertical plane does 1.5 ° of pattern draft, the resistance material ladder boss to 70 ° of planes of upper mold most foot bridge portion height
Spend 3.5-4mm.For convenience of Mold Making, which can squeeze blocking die cavity along week setting.
Working principle: diathermanous round billet material moves to blocking die cavity, and on the basis of big end, lower die squeezes the circular arc R bottom in type groove
Face positioning, press machine strike stroke start, and upper cavity contact blank forces blank deformation, blank to horizontal and vertical extension, when
When blank lateral flow to horizontal bridge portion, upper and lower horizontal bridge portion compresses blank lateral flow resistance and increases, and hinders when with angled step
After hopper contact, clout flow direction is turned back 70 ° of angles, and resistance increases again, enters inclination resistance material with upper mold strike downlink blank
Type groove, and the thickness for tilting resistance material slot is smaller and smaller, tilts the stepped designs of resistance material slot in addition, resistance material power sharply increases, and indulges
Circular conical surface is made into along metal direction to type groove and reduces flow resistance, metal is made to do more longitudinal flows, is full of wrist-pin end of connecting rod.Small end
Head upper and lower mould does not design the boss in blocking hole, in order to avoid influence the axial flowing of metal when bar portion squeezes.Each ladder is vertical
1.5 ° of pattern draft is done in face, since angle is smaller, can increase the adhesive force (gradient of upper mold is 20 °) of forging stock, so that forging
Part is attached to lower die always, facilitates depanning and movement.After the completion of blocking hits stroke, lower knock-pin ejects pre- forging, translation
Finisher to side is intracavitary, positions by pre- forging shape and finish-forging die cavity, and strike carries out finish-forging forming again, and upper mold is with sliding block
After backhaul, lower push rod ejects forging.This extruding type groove is combined together with blocker, it is convenient to omit fall special pulling process,
Shorten process flow, operation is more laborsaving, simple and easy.
In conclusion the utility model eliminates special preforming, reduce the capital investment and phase of shaping equipment
The operator of pass shortens forging technology process；Reduce blank heating times, make blank primary heating can finish-forging at
Shape；It reduces to worker operation skill requirement, simple to operate, blank carries mobile Distance Shortened, reduces labor intensity.It produces
Quality is more stable, furthermore, it is possible to more effectively cope with the product demand of small mount, multi items.
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.
