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, thus during balance, mainly
It is balance one order inertia power.Dual roll type cold-rolling mill uses twin shaft dynamic balancer at present, the most not only arranges fan on crank
Shape balance weight, and on two other axle, also arrange fan-shaped balance weight, one has three axles, and structure is complex, difficult processing
Degree is relatively big, and manufacturing cost is high, and milling train is taken up space bigger.

Bigger problem that technology dual roll type cold-rolling mill uses twin shaft dynamic balancer to cause structure complex and milling train is taken up space.
This utility model is achieved through the following technical solutions:
Dual roll type cold-rolling mill coaxial single order dynamic poise device, including base member case, frame, connecting rod and eccentric gear, described
Eccentric gear is provided with balancing weight A, and described base member case is rotatably connected to weight gear, and this weight gear is provided with balancing weight B,
Weight gear and eccentric gear are in same axis.
The further improvement project of this utility model is that described weight gear turns to contrary with eccentric gear, the angle speed of the two
Spend identical.
This utility model further improvement project is, described balancing weight A is secter pat, and described balancing weight B is secter pat.
This utility model further improvement project is, the both sides of described frame are rotatably connected to two connecting rods, two companies
Bar is rotationally connected with eccentric gear respectively, and eccentric gear engages with the driving gear A being fixedly connected in drive shaft.
This utility model further improvement project is that described weight gear engages with transition wheel, and this transition wheel is with fixing
The driving gear B engagement being connected in drive shaft, described weight gear is two, is respectively arranged at by two eccentric gears.
This utility model further improvement project is that one end of described drive shaft is fixedly connected with belt pulley, this belt
Wheel is in transmission connection with driving means.
This utility model further improvement project is, described drive shaft, the rotating shaft A of eccentric gear, weight gear turn
The rotating shaft C of axle B and transition wheel is rotationally connected with in base member case respectively.
This utility model further improvement project is that described housing slide is connected in base member case.
This utility model compared with prior art, has the advantage that
In this utility model, the pivot center of balancing weight A is same axis with the pivot center of balancing weight B, and structure is the simplest
Single, difficulty of processing is less, low cost of manufacture, and milling train is taken up space less；Weight gear turns to contrary with eccentric gear, the two
Angular velocity is identical, the horizontal component of balancing weight A and balancing weight B centrifugal force and the one order inertia dynamic balance of frame, balancing weight A with join
The vertical component of pouring weight B centrifugal force mutually balances, and balancing weight A is used to the single order of frame with the horizontal component of balancing weight B centrifugal force
The moment sum that property power produces at axis is 0, the most there is not the tilting moment of base member case so that milling train operationally, base
Case is in plateau.
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
