Specific embodiment
The present invention can cold forging machine capable of forging two ends, including frame, die mechanism, Material moving device, upset head mould, drive mechanism are provided with frame and supply hair
The charging hole that base is stretched into, the Material moving device is made up of the first thrust gear and the second thrust gear, and the die mechanism is by the first die mechanism and
Two die mechanisms, also including the mould heart, the mould heart is made up of the left half module heart and the right half module heart, and the left half module heart and the right half module heart are and frame
Offset, semi-circular recesses are equipped with the heart in the left half module heart, the right half module, the left half module heart and the right half module heart are engaged for pressing from both sides
Blank is held, the straight reciprocating motion end of first thrust gear is fixedly connected with the left half module heart, for driving the left half module heart to move back and forth,
The groove of the left half module heart have be right against charging hole position, be right against upset head mould position and relative to the upset head mould slightly toward
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 described right half
The mould heart is moved back and forth, and, with being right against charging hole and being right against the position of upset head mould, upset head mould is mainly by upper die and lower die for the groove of the right half module heart
Composition, first die mechanism, second die mechanism are respectively positioned at the both sides of the mould heart, the linear reciprocation fortune of first die mechanism
Moved end is fixedly connected with upper mould, and lower mould is arranged in frame, and lower mould forms sliding and coordinates with frame, and second die mechanism is used to drive lower mould to do
Straight reciprocating motion;Blank is in the position for being right against upset head mould, and first die mechanism and second die mechanism are engaged, are used for
Make upper die and lower die end simultaneously equal with blank respectively form first time top pressure to coordinate, relative to the upset head mould slightly toward the described first passage machine
The position of structure, the second die mechanism is additionally operable to lower mould and forms second top pressure with the blank, blank is departed from lower mould.The course of work of the invention is:
Blank enters in frame from charging hole, and now the groove of the right half module heart is located at just to the position of charging hole, and the first thrust gear drives the left half module heart to move
The groove for moving the left half module heart is just engaged and for blank to be fixed on the chamber that two grooves are formed to the position of charging hole, the left half module heart and the right half module heart
It is interior;Afterwards, a pusher and the second thrust gear are pushed away while driving the left half module heart and the right half module heart to be moved to upset head mould direction respectively, now,
The suitable damped part of the left half module heart, for coordinating the left half module heart that blank is fixed in groove, in this moving process, blank is cut off in realization
(being provided with carbide bit in the end of charging hole, this is as good as with prior art), blank is finally moved into and is right against the position of upset head mould simultaneously
And blank is detained on the position, during the delay, the first die mechanism drives upper mould to form top pressure to blank, and by the other end of blank
Release groove;Now the second die mechanism also forms top pressure to lower mould, forms the first die mechanism and the second die mechanism and blank is entered simultaneously respectively
Row upsetting;After completing upsetting, the second thrust gear drives the right half module heart to be moved to the position for being right against charging hole;To realize smooth blanking, the
One thrust gear then drive the left half module heart to relative to the upset head mould slightly toward first thrust gear position, i.e., it is anti-with the right half module heart
To motion;During the left half module heart deviates just to upset head mould, the second die mechanism forms top pressure and coordinates with lower mould again, makes after upsetting section
Blank depart from lower mould;After the completion of, the first thrust gear drives the left half module heart to be moved to the position just to charging hole again.The present invention is by setting
First die mechanism, the second die mechanism and Material moving device, not only realize the purpose to blank two ends all jumping-ups, and the first die mechanism and
Second die mechanism carries out upsetting to the two ends of blank respectively, makes the two ends upsetting formation effect of blank good.In the present invention, in the mould heart and frame
Between can also increase backing plate to avoid frame from wearing and tearing.
First die mechanism is mainly made up of connecting rod, ram, and it is as good as with prior art, and the two ends of connecting rod are connected with ram and bent axle respectively, ram peace
In frame, bent axle, connecting rod, ram form slider-crank mechanism.In this implementation row, ram is straight reciprocating motion end.As this reality
The direct deformation of example is applied, the first die mechanism can also be formed by cylinder or hydraulic cylinder.Controller controlled by controlling magnetic valve cylinder or
Hydraulic cylinder works, make cylinder or the second die mechanism of hydraulic cylinder cooperation carry out upsetting to blank.Wherein, the piston of ram, cylinder or hydraulic cylinder
Bar is straight reciprocating motion end.
