Description
Technical field
The present invention relates to a kind of valve blank bar portion curve straightener, for being specifically used to school after valve blank is heat-treated
Straight special purpose machine tool, can especially reach the purpose of engine valve stem alignment.
Background technology
At present, domestic size valve factory is all the two methods used：The first is artificial alignment method, i.e., with one specially
The bar portion for supporting valve with support is allowed to balance, and is beated with dial gauge measurement bar, in the bounce maximum heavy percussion of hammer,
It is allowed to obtain reversible deformation；Second is thread rolling machine alignment method, that is, buys a thread rolling machine and return by transforming thread rolling rolling disk
Alignment is carried out to engine valve stem afterwards.And our company is the second method used, alignment process is significantly improved really, but rework rate
It is very high, so a large amount of manpowers are caused, material resources, the waste of financial resources.
The content of the invention
The present invention is directed to drawbacks described above, it is therefore intended that offer one kind is simple in construction, valve blank can be heat-treated well
A kind of valve blank bar portion curve straightener of alignment is carried out afterwards.
It is for this technical solution adopted by the present invention：The present invention includes blanking rack（4）, it is arranged on blanking rack（4）Both sides
Nip drum mechanism, the nip drum mechanism include the fixed fixed nip drum in side（6）With the horizontally movable activity of opposite side
Nip drum（7）, the valve is positioned at blanking rack（4）Above and positioned at the fixed nip drum（6）With movable nip drum（7）Between；
The blanking rack（4）It is upper that nip drum mechanism rear end is provided with the adjustable support frame in position（9）, support frame as described above
（9）Pan portion for supporting the valve.
The fixed nip drum（6）Include two pressing rollers one（61）, two pressing roller one（61）Between spacing be 2-4
Piece pressing roller one（61）Thickness.
The movable nip drum（7）Include a pressing roller two（71）, the pressing roller two（71）Positioned at two pressing rollers one
（61）Between center.
The movable nip drum（7）By power transmission shaft（11）It is driven realization activity nip drum（7）Move horizontally.
Support frame as described above（9）The hopper of accommodating valve is provided with position（10）.
The blanking rack（4）Front end is provided with elevator（3）, and in the elevator（3）Front end is provided with shake material machine
（1）.
The shake material machine（1）And elevator（3）Between be provided with tripper one（2）, the blanking rack（4）Set on path
There is tripper two（5）.
Include electrical appliance kit（8）, the electrical appliance kit（8）Control during for being operated to each part.
It is an advantage of the invention that：The straightener of the present invention can not only reach the requirement of bounce, and will not valve bar
Leave residual compressive stress in portion.Production efficiency is greatly improved, labor intensity is reduced.
The present invention：The constructional device for coordinating 1 pressing roller using the pressing roller of 2 monomers carries out curve school to engine valve stem
Directly, solve several pieces overall nip drums to destroy the interior tissue for forcing into submission engine valve stem, while also improving production efficiency, without doing over again one
Secondary very qualification rate, reduces labor intensity, saves production cost.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
1 it is shake material machine in figure, 2 is that tripper one, 3 is elevator, 4 is blanking rack, 5 is that tripper two, 6 is fixed pressure
Rolling, 7 be movable nip drum, 8 be electrical appliance kit, 9 be support frame, 10 be hopper, 11 be power transmission shaft；
61 be that pressing roller one, 71 is pressing roller two.
Embodiment
The present invention includes blanking rack 4, is arranged on the nip drum mechanism of the both sides of blanking rack 4, and the nip drum mechanism includes side
The fixed horizontally movable movable nip drum 7 of fixed nip drum 6 and opposite side, the valve is located in blanking rack 4 and is located at
Between the fixed nip drum 6 and movable nip drum 7；
Nip drum mechanism rear end is provided with the adjustable support frame 9 in position in the blanking rack 4, support frame as described above 9 is used for
Support the pan portion of the valve.
The spacing that the fixed nip drum 6 includes between two pressing rollers 1, two pressing roller 1 is 2-4 piece nip drums
Take turns 1 thickness.
The movable nip drum 7 includes a pressing roller 2 71, and the pressing roller 2 71 is located between two pressing rollers 1
Center.
The movable nip drum 7 is driven moving horizontally for realization activity nip drum 7 by power transmission shaft 11.
The hopper 10 of accommodating valve is provided with the position of support frame as described above 9.
The front end of blanking rack 4 is provided with elevator 3, and is provided with the front end of elevator 3 shake material machine 1.
It is provided between the shake material machine 1 and elevator 3 on tripper 1, the path of blanking rack 4 and is provided with tripper
25.
Include electrical appliance kit 8, the control when electrical appliance kit 8 is used to operate each part.
The present invention is described further below, to be better understood by the present invention：
It is three nip drums to making spacer in the pressing roller 1 that the left side is two panels monomer, two panels pressing roller 1 at its pressure roller into
Take turns 1 thickness, the right is a piece of pressing roller 2 71, is placed in the center of spacer in two panels pressing roller 1, and valve is put down
What is put down, having installed a support frame 9 additional in Valve Disc is used for supporting valve, it is to avoid valve is overweight because of pan portion, and weightlessness is drawn
Nip drum mechanism causes damage to the secondary rolled of rod end at the end of playing valve alignment.The present invention mixes a high-power shake material machine 1,
Automatic upper elevator 3.Product by it is artificial be discharged to shake material machine 1 and uniformly separate by elevator 3 valve is delivered into automatic distributor 1
Fall into again in blanking rack 4, then pressing roll mechanism one stroke of work releases valve, the work so so circulated.By so
Aligning method, any position of valve is all without leaving residual compressive stress, and engine valve stem linearity reaches technological requirement,
And ensure that larger alignment amount once carries out alignment while being applied without phenomenon of doing over again, therefore well.
Product of the present invention falls into two panels fixation nip drum 6 and a collection of movable nip drum 7 does feed motion and reach bar portion curve school
Straight purpose, while carry out angle adjustment to tache motorice, and using axial thrust when feeding by valve by axial thrust so as to
Make engine valve stem in alignment to outside play, valve is departed from collimation region, when valve exits collimation region outward by can
The disk of the support frame 9 support Valve Disc of regulation, it is to avoid the injury of valve bar portion secondary extrusion caused by weightless, the good valve of alignment
Product box is fallen into by hopper 10；Movable nip drum 7 is driven by power transmission shaft 11, and electrical equipment is by PLC controls.
