Description
Technical field
A kind of valve blank bar portion curve straightener is the utility model is related to, for specially being used after valve blank is heat-treated
Come the special purpose machine tool being straightened, it can especially achieve the purpose that engine valve stem is straightened.
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
It is allowed to balance with the bar portion of stent support valve, is beated with dial gauge measurement bar, in the heavy percussion of bounce maximum 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
Engine valve stem is straightened afterwards.And our company is the second method used, alignment process significantly improves really, but rework rate
It is very high, so a large amount of manpowers are caused, material resources, the waste of financial resources.
Utility model content
The utility model in view of the foregoing drawbacks, and it is an object of the present invention to provide it is a kind of it is simple in structure, can be well to valve blank heat
A kind of valve blank bar portion curve straightener being straightened after processing.
The technical solution adopted in the utility model is for this：The utility model includes blanking rack, is arranged on blanking rack two
The nip drum mechanism of side, the nip drum mechanism include the fixed fixed nip drum in side and the horizontally movable activity pressure of opposite side
Rolling, the valve are located in blanking rack and between the fixed nip drum and movable nip drums；
Nip drum mechanism rear end is provided with the adjustable supporting rack in position in the blanking rack, support frame as described above is used for
Support the pan portion of the valve.
The fixed nip drum includes two pressing rollers one, and the spacing between two pressing roller one is 2-4 pieces pressing roller one
Thickness.
The activity nip drum includes a pressing roller two, centre bit of the pressing roller two between two pressing rollers one
Put.
Activity nip drum the moving horizontally by transmission shaft driven realization activity nip drum.
The lower hopper of accommodating valve is provided with support frame as described above position.
The blanking rack front end is provided with elevator, and shake material machine is provided with the elevator front end.
Tripper one is provided between the shake material machine and elevator, tripper two is provided with the blanking rack path.
Include electrical appliance kit, the control when electrical appliance kit is used to operate each component.
The utility model has the advantages that：The straightener of the utility model can not only reach the requirement of bounce, and will not be
The bar portion of valve leaves residual compressive stress.Production efficiency is greatly improved, reduces labor intensity.
The utility model：Coordinate the constructional device of 1 pressing roller to engine valve stem march using the pressing roller of 2 monomers
Line is straightened, and solves several pieces overall nip drums and the interior tissue for forcing into submission engine valve stem is destroyed, while also improves production efficiency, without returning
Work once very qualification rate, reduces labor intensity, saves production cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
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 activity nip drum, 8 be electrical appliance kit, 9 be supporting rack, 10 be lower hopper, 11 be transmission shaft；
61 be that pressing roller one, 71 is pressing roller two.
Embodiment
The utility model includes blanking rack 4, is arranged on the nip drum mechanism of 4 both sides of blanking rack, and the nip drum mechanism includes
The fixed fixed nip drum 6 in side and the horizontally movable movable nip drum 7 of opposite side, the valve be located in blanking rack 4 and
Between the fixed nip drum 6 and movable nip drum 7；
Nip drum mechanism rear end is provided with the adjustable supporting rack 9 in position, support frame as described above 9 in the blanking rack 4
It is used to support the pan portion of the valve.
The fixed nip drum 6 includes two pressing rollers 1, and the spacing between two pressing roller 1 is 2-4 piece nip drums
Take turns one 61 thickness.
The activity nip drum 7 includes a pressing roller 2 71, and the pressing roller 2 71 is between two pressing rollers 1
Center.
The activity nip drum 7 is driven moving horizontally for realization activity nip drum 7 by transmission shaft 11.
The lower hopper 10 of accommodating valve is provided with 9 position of support frame as described above.
4 front end of blanking rack is provided with elevator 3, and shake material machine 1 is provided with 3 front end of elevator.
Tripper 1 is provided between the shake material machine 1 and elevator 3, tripper is provided with 4 path of blanking rack
25.
Include electrical appliance kit 8, the control when electrical appliance kit 8 is used to operate each component.
The utility model is described further below, to be better understood by the utility model：
To making the pressing roller 1 that the left side is two panels monomer at its pressure roller into, spacer is three pieces in two panels pressing roller 1
The thickness of pressing roller 1, the right are a piece of pressing roller 2 71, are placed in the center of spacer in two panels pressing roller 1, gas
Door puts down what is put down, and having installed a supporting rack 9 additional in Valve Disc is used for supporting valve, avoids valve because pan portion is overweight, loses
Nip drum mechanism causes to damage to the secondary rolled of rod end at the end of causing valve alignment again.The utility model mix one it is high-power
