Abstract
The invention belongs to straightener appliance technology, more particularly to a kind of stable anti-rock hydraulic pressure retaining system of straightener roll of straightener.The invention discloses the stable anti-rock hydraulic pressure retaining system of straightener roll of straightener, including straightener locking cylinder, piston hole is offered on described straightener locking cylinder, described piston hole is provided with piston rod, piston hole is in contact with regulation screw axis, described straightener locking cylinder is connected with oil pipe, and return check valve and two-position four-way solenoid directional control valve are provided with described oil pipe.The beneficial effects of the invention are as follows：Smoothing roll is stably aligned steel pipe and obtain positive effect, so as to quickly disposable aligning steel pipe, reduce and rectify the not straight time aligned back and forth, so as to keep up with the rhythm of hot rolling line, improve the yield of company, reduce equipment loss.
Description
Technical field
The invention belongs to straightener appliance technology, more particularly to a kind of stable anti-shake hydrodynamic pressure of straightener roll of straightener to protect
Pressure system.
Background technology
From on July 18th, 08 go into operation since, my Steel tube Co., Ltd steps into the right path, reach production it is wide in variety, it is complete in specifications,
From Φ 85 to Φ, 265 steel pipes can produce, and meet market demands for expanding production business scope, rocked for straightener roll of straightener
Not straight steel pipe is rectified, has a strong impact on quality requirement, through research, because straightener cylinder piston rod and regulation screw axis contact area are too small
It is more than cylinder thrust with twisting resistance during aligning, and smoothing roll is produced shaking phenomenon in straightening process, has a strong impact on smoothing roll
Service life and steel tube surface quality, constrain aligning machine production line yield, increase equipment loss and maintenance cost.
The content of the invention
It is an object of the invention to solve the problems, such as techniques discussed above, there is provided one kind makes smoothing roll stably align steel pipe to obtain
To positive effect, so as to quickly disposable aligning steel pipe, reduce and rectify the not straight time aligned back and forth, so as to keep up with
The rhythm of hot rolling line, the yield of company is improved, reduce the stable anti-shake hydrodynamic pressure pressurize of straightener roll of straightener of equipment loss
System, its technical scheme are as follows：
The stable anti-rock hydraulic pressure retaining system of straightener roll of straightener, it is characterised in that including straightener locking cylinder, described aligning
Piston hole is offered on machine locking cylinder, described piston hole is provided with piston rod, and piston hole is in contact with regulation screw axis, described
Straightener locking cylinder be connected with oil pipe, return check valve and two-position four-way solenoid directional control valve are provided with described oil pipe.
Preferred embodiment is a diameter of 34cm of described oil pipe.
Preferred embodiment is that the contact area of described piston hole and regulation screw axis is 120-150 square centimeters.
The stable anti-rock hydraulic pressure retaining system of straightener roll of straightener provided by the invention, 1, utilize the existing locking of straightener
Cylinder piston rod hole carries out 1.3 times and expands machining piston rod aperture hole.
2nd, using the existing valve platform of straightener, pipeline increase laying is carried out, return check valve is installed on pipeline, prevented
Twisting resistance crosses the backflow of ambassador's fluid when it is aligned.
3rd, using new major diameter locking cylinder, simultaneously installation and debugging are good.
Operation principle is：Straightener unlatching → straightener locking cylinder locking → straightener foreground roller-way lifts → roller bed rotation
→ steel pipe by roller-way be sent into straightener → smoothing roll rotate aligning steel pipe → straightener backstage roller-way open → it is quick by strong steel pipe
Output.
The beneficial effects of the invention are as follows：Smoothing roll is stably aligned steel pipe and obtain positive effect, so as to quickly once
Property aligning steel pipe, reduce and rectify the not straight time aligned back and forth, so as to keep up with the rhythm of hot rolling line, improve company
Yield, reduce equipment loss.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
With reference to Fig. 1 specific illustrative embodiments：
The stable anti-rock hydraulic pressure retaining system of straightener roll of straightener, including straightener locking cylinder 1, described straightener locking cylinder 1
On offer piston hole 2, described piston hole 2 is provided with piston rod 3, and piston hole 3 is in contact with regulation screw axis 4, described
Straightener locking cylinder is connected with oil pipe 5, and return check valve 6 and two-position four-way solenoid directional control valve 7 are provided with described oil pipe 5.
Preferred embodiment is a diameter of 34cm of described oil pipe.
Preferred embodiment is that the contact area of described piston hole and regulation screw axis is 120-150 square centimeters.
The stable anti-rock hydraulic pressure retaining system of straightener roll of straightener, make because straightener cylinder piston rod and regulation screw axis connect
Twisting resistance is more than cylinder thrust when contacting surface product is too small and aligns, and influences the service life of smoothing roll and the surface quality of steel pipe,
To straightener locking cylinder piston rod and the increase of regulation screw axis contact area, the adjustment of pipe diameter increase and installation oil return list
To valve, so that oil mass significantly increases, excessive twisting resistance makes fluid backflow phenomenon when preventing to be aligned, and smoothing roll is locked
Positive effect, the aligning steel pipe time is shortened, and be not in the phenomenon for aligning steel pipe back and forth, it is not only full by improving
Foot hot rolling rhythm of production, also meets quality of production technological requirement, from and reduce production cost and equipment cost, improve
Production efficiency, more improve the competitiveness of our products.
