Preferred embodiment on the basis of said program and as said program：First cam has the first protrusion and second Protrusion, the first protrusion, the second protrusion are used to that heading swing arm and lower die is made to be respectively formed top pressure cooperation.

Specific implementation mode

The present invention can cold forging machine capable of forging two ends, including rack, die mechanism, Material moving device, upset head mould, driving mechanism, The feed opening stretched into for blank is equipped in rack, the Material moving device is made of the first thrust gear and the second thrust gear, The die mechanism further includes the mould heart by the first die mechanism and the second die mechanism, and the mould heart is by the left half module heart and right half The mould heart forms, and the left half module heart and the right half module heart offset with rack, the left half module heart, the right half module in the heart Semi-circular recesses are equipped with, the left half module heart and the right half module heart are matched for blank, the first passage machine to be clamped The straight reciprocating motion end of structure is fixedly connected with the left half module heart, for driving the left half module heart to move back and forth, the left half module The groove of the heart, which has, to be right against the position of feed opening, is right against the position of upset head mould and slightly biased relative to the upset head mould To the position of first thrust gear, the straight reciprocating motion end of second thrust gear is fixedly connected with the right half module heart, For driving the right half module heart to move back and forth, the groove of the right half module heart, which has, to be right against feed opening and is right against upset head mould Position, upset head mould are mainly made of upper die and lower die, and first die mechanism, second die mechanism are located at institute The both sides of the mould heart are stated, the straight reciprocating motion end of first die mechanism is fixedly connected with upper mold, and lower die is mounted in rack, Lower die forms sliding cooperation with rack, and second die mechanism is for driving lower die to do straight reciprocating motion；Blank is in just For the position of upset head mould, first die mechanism and second die mechanism match, for making upper die and lower die The cooperation of first time top pressure is formed with the equal end of blank simultaneously respectively, relative to the upset head mould slightly toward first passage The position of mechanism, the second die mechanism are additionally operable to lower die and form second of top pressure with the blank, and blank is made to be detached from lower die.This hair The bright course of work is：Blank enters from feed opening in rack, and the groove of the right half module heart is located at the position of face feed opening at this time, First thrust gear drive the left half module heart be moved to the left half module heart groove face feed opening position, the left half module heart and right half module The heart, which matches, to be fixed on blank in the chamber of two grooves formation；Later, a pusher and the second thrust gear are pushed away simultaneously The left half module heart and the right half module heart is driven to be moved to upset head mould direction respectively, at this point, the suitable damped part of the left half module heart, is used In coordinating the left half module heart that blank is fixed in groove, in this moving process, realizes and cut off blank (in the end of feed opening Equipped with carbide bit, this is no different with the prior art), blank is finally moved into the position for being right against upset head mould and hair Base is detained on the position, and during the delay, the first die mechanism drives upper mold to form top pressure to blank, and by the another of blank One end releases groove；The second die mechanism also forms top pressure to lower die at this time, forms the first die mechanism and the second die punching machine Structure carries out upsetting to blank simultaneously respectively；After completing upsetting, the second thrust gear drives the right half module heart to being right against feed opening It moves position；To realize smooth blanking, the first thrust gear then drive the left half module heart to relative to the upset head mould slightly toward The position of first thrust gear, the i.e. counter motion with the right half module heart；During the left half module heart deviates face upset head mould, Second die mechanism forms top pressure cooperation with lower mold again, and the blank after upsetting section is made to be detached from lower mold；After the completion, first Thrust gear drives the left half module heart to be moved to the position of face feed opening again.The present invention is by being arranged the first die mechanism, second Die mechanism and Material moving device not only realize the purpose to blank both ends all jumping-ups, and the first die mechanism and the second punch die Mechanism carries out upsetting to the both ends of blank respectively, keeps the both ends upsetting formation effect of blank good.In the present invention, in the mould heart and machine Backing plate can also be increased between frame to wear to avoid rack.

First die mechanism is mainly made of connecting rod, ram, is no different with the prior art, the both ends of connecting rod respectively with ram It is connected with bent axle, ram is mounted in rack, and bent axle, connecting rod, ram form slider-crank mechanism.In this implementation column, ram For straight reciprocating motion end.As the direct deformation of the present embodiment, the first die mechanism can also be by cylinder or hydraulic cylinder shape At.By controlling solenoid valve, to control cylinder, either hydraulic cylinder works make cylinder or hydraulic cylinder coordinate the second punch die to controller Mechanism carries out upsetting to blank.Wherein, the piston rod of ram, cylinder or hydraulic cylinder is straight reciprocating motion end.
