Description
Technical field
This utility model relates to mechanical field, is specifically related to the second order dynamic poise device of dual roll type cold-rolling mill.
Background technology
Cold pilger mill is to utilize annular distance shape that hollow forging is carried out the process equipment of cold conditions rolling.These facility have preferable cogging
Can, also can roll the metal seamless tube of general precision.Cold pilger mill maximum feature is that stock utilization is high, and precision and surface thick
Rugosity is superior to drawn tube.Cold-rolling mill is made up of operating mechanism and drive mechanism, wherein: operating mechanism by frame, roll, roll
The part such as roller bearing, roll-adjusting gears, guide device is constituted；Drive mechanism by herringbone gear, reductor, roll, coupling spindle,
The part such as shaft coupling is constituted.Cold-rolling mill uses motor to pull reinforcing bar, utilizes the load bearing roller of cold-rolling mill, working roll jointly power to be executed
It is added on two faces of hollow forging.Realize rolling out the purpose of different-diameter hollow forging by the size changing two roll seams.Mesh
Before, the operating mechanism of dual roll type cold-rolling mill can be reduced to slider-crank mechanism.For making pipe pass through above transmission main shaft, it is necessary to
Making rolling centerline be higher than crank up centrage, therefore, the operating mechanism of cold-rolling mill, i.e. stand arrangement motor system, mostly is
One offset slider-crank mechanism.For slider-crank mechanism, no matter whether the invariablenes turning speed of crank, produces used in motion always
Property power, it will be directly connected to duty and the service life of cold-rolling mill.Further, the size of inertia force and the quality of component
Proportional with acceleration, i.e. with the quality of component, throw of crankshaft, crank rolling velocity square proportional.And dual roll type cold-rolling mill moves
The quality of dynamic part (operating mechanism) is the biggest, thus operating mechanism is the biggest at the inertia force produced at the volley, needs
Certain way is taked to be balanced.The inertia force produced when frame moves back and forth is divided into one order inertia power and second-order inertia
Power.Second-order inertia power is less compared to one order inertia power, is generally only the 10 ~ 18% of one order inertia power, and current manufacturing enterprise is examining
When considering the balance of milling train, mainly balance one order inertia power, does not accounts for second-order inertia power.Also because of current dual roll type cold-rolling mill
Use twin shaft dynamic balancer, on crank, the most not only arrange fan-shaped balance weight, and also arrange on two other axle
Fan-shaped balance weight, one has three axles, is not easy to arrange second order balancing weight in base member case, thus results at milling train in fortune at a high speed
During row, second-order inertia power can still result in base member case shake.
Summary of the invention
The technical problems to be solved in the utility model is the second order dynamic poise device of dual roll type cold-rolling mill, solves existing skill
If art rolling mill main balance one order inertia power causes the second-order inertia power when milling train is at high-speed cruising to can still result in base member case shake
