Seamless steel pipe is the essential important materials of modern society, in the neck such as defence and military, venue construction, pipeline
Domain uses quite varied, and cold rolling is the current production main mode of production of thin-wall seamless steel pipe, with good in economic efficiency, product matter
The features such as measuring high.The cold pilger mill technology of China mostlys come from the former Soviet Union, and operationally frame passes through traditional cold pilger mill
The crank connecting link of transmission mechanism moves reciprocatingly, and carries out repeat-rolling finishing to steel pipe, due to crank connecting link itself, leads
Rate curve mechanical periodicity during cause frame operation, instrument and work speed difference also mechanical periodicity, influence product surface quality, another
Aspect, larger inertia force is easily produced in extreme position, is caused to vibrate and is impacted.It is right with the increasingly raising of scientific and technological level
Tube product quality, production environment requirement it is growing day by day, this is accomplished by the movement velocity and acceleration of milling train work housing
It is more steady, reduce the inertia force of work housing.
Traditional cold pilger mill is main by rolling equipment, material feeding platform, discharge pedestal, hydraulic control unit, lubricating and cooling group
Into.Wherein the workflow of rolling equipment is substantially：Motor output torque is delivered on travelling gear by belt pulley, via tooth
Wheel transmission finally imparts power to frame by crank connecting link, and work housing is under the drive of connecting rod by means of sliding block and roller edge
Track on base is moved back and forth, and fixed steel pipe is rolled.
In traditional structure, toggle self-characteristic is limited to, the speed and acceleration of its mechanical periodicity can be to rolling
Part quality makes a significant impact, and causes larger inertia force because frame deadweight is larger, makes vibration and noise.
Utility model content
The utility model purpose is to provide that a kind of product quality is high, inertia force is low, vibration and noise reducing application non-circular gear
The cold-rolling equipment of transmission.
To achieve the above object, following technical scheme is employed：The utility model mainly includes motor, drive pulley, subtracted
Fast case, base, framework lateral plate, bottom roll support, bottom roll, topping roll, topping roll support, frame upper plate, four frame sides
Plate is respectively cooperating with being arranged on upper and lower roll support and the surrounding of upper and lower roll, collectively constitutes work housing, frame upper plate peace
At the top of the work housing, floor installation in the bottom of work housing, the reduction box by fix sun gear, planet Knucle-gear,
Tie-rod H, planet non-circular gear, rotation sun gear, drive gear A, drive gear B, driving rack A, driving rack B compositions；Electricity
Machine is connected by drive pulley with the tie-rod H in reduction box, and tie-rod H two ends are socketed planet Knucle-gear and the non-knuckle-tooth of planet respectively
Wheel, planet Knucle-gear is engaged with fixed sun gear, and planet non-circular gear is engaged with rotating sun gear, rotates sun gear and sliding tooth
Take turns A, drive gear B coaxially connected, drive gear A is engaged with driving rack A, drive gear B is engaged with driving rack B, is driven
Rack A and driving rack B one end are weldingly fixed on work housing.
Compared with prior art, the utility model has the following advantages that：
1st, more preferable speed, accelerating curve can be obtained, the operation of rolling is more steady.
2nd, robust motion is good, and impact shock is small, and product quality is high.
