Detailed description of the invention
nullThe Cold header at Ke Dun two of the present invention，Including frame、Die mechanism、Material moving device、Upset head mould、Driving mechanism，Frame is provided with mean for the charging hole that blank stretches into，Described Material moving device is made up of the first thrust gear and the second thrust gear，Described die mechanism is by the first die mechanism and the second die mechanism，Also include the mould heart，The described mould heart is made up of the left half module heart and the right half module heart，The described left half module heart and the described right half module heart all offset with frame，At the described left half module heart、Described right half module is equipped with semi-circular recesses in the heart，The described left half module heart and the described right half module heart match for clamping blank，The straight reciprocating motion end of described first thrust gear is fixing with the left half module heart to be connected，For driving the described left half module heart to move back and forth，The groove of the described left half module heart has the position being right against charging hole、It is right against the position of upset head mould and relative to the described upset head mould position slightly toward described first thrust gear，The straight reciprocating motion end of described second thrust gear is fixing with the right half module heart to be connected，For driving the described right half module heart to move back and forth，The groove of the right half module heart has the position being right against charging hole He being right against upset head mould，Upset head mould is mainly made up of upper die and lower die，Described first die mechanism、Described second die mechanism lays respectively at the both sides of the described mould heart，The straight reciprocating motion end of described first die mechanism is fixing with upper mould to be connected，Counterdie is arranged in frame，Counterdie forms sliding with frame and coordinates，Described second die mechanism is used for driving counterdie to do straight reciprocating motion；Blank is in the position being right against upset head mould; described first die mechanism and described second die mechanism match; end for making upper die and lower die simultaneously equal with blank respectively is formed pushes up press-fit for the first time; relative to the described upset head mould position slightly toward described first thrust gear; second die mechanism is additionally operable to counterdie and pushes up pressure with described blank formation second time, makes blank depart from counterdie.The work process of the present invention is: blank enters in frame from charging hole, now the groove of the right half module heart is positioned at just position to charging hole, first thrust gear drives the left half module heart to move to the groove of the left half module heart just position to charging hole, and the left half module heart and the right half module heart match and be fixed on by blank in the chamber that two grooves are formed；Afterwards, push away a pusher and the second thrust gear drives the left half module heart and the right half module heart to move to upset head mould direction simultaneously respectively, now, the suitable damped part of the left half module heart, for coordinating the left half module heart to be fixed in groove by blank, in this moving process, realize cutting off blank (being provided with carbide bit in the end of charging hole, this and prior art are as good as), blank is finally moved into the position being right against upset head mould and blank and is detained on this position, during this delay, first die mechanism drives upper mould that blank is formed top pressure, and groove is released in the other end of blank；Now counterdie is also formed top pressure by the second die mechanism, forms the first die mechanism and blank is carried out upsetting by the second die mechanism respectively simultaneously；After completing upsetting, the second thrust gear drives the right half module heart to move to the position being right against charging hole；For realizing smooth blanking, the first thrust gear then drives the left half module heart to relative to the described upset head mould position slightly toward described first thrust gear, namely with the adverse movement of the right half module heart；During the deviation of the left half module heart is just to upset head mould, the second die mechanism forms top press-fit with lower mold again, makes the blank after upsetting section depart from lower mold；After completing, the first thrust gear drives the left half module heart to just the position of charging hole being moved again.The present invention is by arranging the 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 two ends of blank are carried out upsetting by the first die mechanism and the second die mechanism respectively, the two ends upsetting formation making blank is effective.In the present invention, backing plate can also be increased between the mould heart and frame to avoid frame to wear and tear.
First die mechanism is mainly made up of connecting rod, ram, and itself and prior art are as good as, and the two ends of connecting rod are connected with ram and bent axle respectively, and ram is arranged in frame, and bent axle, connecting rod, ram form slider-crank mechanism.In this enforcement arranges, ram is straight reciprocating motion end.As the directly deformation of the present embodiment, the first die mechanism can also be formed by cylinder or hydraulic cylinder.Controller controls cylinder or hydraulic cylinder works by controlling electromagnetic valve, makes cylinder or hydraulic cylinder coordinate the second die mechanism that blank is carried out upsetting.Wherein, the piston rod of ram, cylinder or hydraulic cylinder is straight reciprocating motion end.
