Description
Technical field
The utility model is related to the technical field of cold pilger mill, and especially one kind is at a high speed and guarantee frame running is smoothly cold
The new driving structure of pipe mill.
Background technology
Cold pilger mill is in cold-rolled process is implemented, it is necessary to move frame equipped with a kind of periodic, the frame is by swingingly
Drive.Therefore, using a kind of crankshaft transmission mechanism by motor-driven, for the inertia force of balance frame, crankshaft transmission machine
Structure is provided with balance weight, but the balance weight is in most cases not sufficient to adequately balance inertial force.Inertia force is produced to transmission system
Clash into, vibrate, the service life of driving parts can be reduced.In order to reduce influence of the inertia to system, traditional method is to subtract
The velocity of rotation of small crank linkage, this method is cost to sacrifice the production efficiency of product, and inadvisable.
In most cases using the bent axle with dual crank throw, these bent axles cause that frame is reciprocally moved by connecting rod,
The inertia force that moves back and forth generation that balance weight partial equilibrium on additional shaft on bent axle and other rotations passes through frame,
But manufacture and operating cost are costly；Simple Eccentric Gear-drive is also used, by putting down that eccentric gear can be configured
Weighing apparatus limited mass, although manufacturing expense is relatively low, but does not have due counterbalance effect.
At present, lower-cost drive mechanism is using singly turning axle, and singly turns the fan that counterweight is increased on the connecting lever of axle
Shape balancing weight, good balance effect, but speed can not be too fast.The cold pilger mill fast for rate request, it may appear that vertical direction
Weighting power cannot balance, cause gantry motion unstable；In addition, the gear housing of existing drive mechanism both sides is not closed,
Rolling mill practice oil is easily mixed into gear lubricant so that gear lubricant is contaminated, and influences service life of equipment, so anxious
One kind need to be designed does not increase manufacture, operating cost, counterbalance effect, improve production efficiency is improved as much as possible, it is ensured that frame is steady
The drive mechanism of the cold pilger mill of periodic motion.
