Description
Technical field
The utility model is related to a kind of additional equilibrium device, more particularly to a kind of balanced controls of cold pilger mill.
Background technology
The impulse stroke of current rack of cold pipe mill be mostly by bent axle rotate drivening rod slider-crank mechanism Lai
Complete the reciprocating motion of frame.Cold pilger mill is when running at high speed, for frame reciprocating in slider-crank mechanism, with
And the component such as reciprocating connecting rod, because their barycenter acceleration and angular acceleration can produce very big cyclically-varying
Inertia force and moment of inertia.This power and torque can cause the strong vibration of cold pilger mill and noise, aggravate the abrasion of parts
And fatigue failure, the kinematic accuracy and robust motion of reducing mechanism.The technical measures used at present have：(1) flywheel energy storage delays
Flushing device, complicated, manufacturing cost is high；(2) also driven in addition to eccentric mass is added on bent axle using vertical links another
The sliding block in vertical direction is covered to balance；The equipment of this mode needs to build a very deep melt pit, and civil engineering difficulty is larger, by
Located underground in whole balance system, maintenance cost is higher；(3) balanced using one or more planetary mechanisms, counterbalance effect
It is very good, but it is complicated, and installation difficulty is big；(4) balance weight horizontal arrangement is used, two sets of sides are operated by Bevel Gear Transmission
To opposite balance system, its structure is also more complicated.
Utility model content
The utility model in view of the shortcomings of the prior art, provide a kind of lightweight, the easy cold pilger mill of assembly technology it is flat
Weigh mechanism.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of cold pilger mill
Balanced controls, including frame, guide rail, connecting rod and driven gear and driving gear are provided with sector on the driven gear
Connecting rod described in two groups has been placed in parallel in chamber, gear-box, be provided with described in two groups on the inside of connecting rod interconnection driven gear and
It is connected on the outside of fan-shaped balance weight, the driven gear with connecting rod described in one group, on the outside of the fan-shaped balance weight and described in another group
Connecting rod is connected, and the driven gear is engaged with the driving gear.The quality of balance weight be quality by frame and connecting rod and
What throw of crankshaft was calculated, the frame of the different quality balance weight quality different from connecting rod and throw of crankshaft needs coordinates,
Balance weight optimum balance quality is chosen in the minimum optimization aim of residual inertia force maximum.
In such scheme, it is preferred that the driven gear is set to one.
In such scheme, it is preferred that the driven gear rear is provided with a balance gear, institute by the connecting rod direction
Balance gear is stated to engage with the driven gear.
In such scheme, it is preferred that the driven gear has the identical number of teeth and modulus with the balance gear, effectively
The stability of safeguard work.
In such scheme, it is preferred that be provided with fan-shaped chamber on the balance gear.
In such scheme, it is preferred that the fan-shaped balance weight respectively with the driven gear and the balance gear one by one
It is correspondingly arranged at opposite side.
In such scheme, it is preferred that be provided with axis hole on the fan-shaped balance weight.
In such scheme, it is preferred that the connected mode of the fan-shaped balance weight and the driven gear is flat key and rotating shaft
Connection, to ensure that both relative positions are consistent all the time.
In such scheme, it is preferred that the connected mode of the fan-shaped balance weight and the balance gear is flat key and rotating shaft
Connection, to ensure that both relative positions are consistent all the time.
The utility model compared with prior art, has the advantages that：The complete equipilibrium of mechanism inertia force is for song
Handle slide block mechanism is difficult to realize, though in theory can be with complete equipilibrium, but because the balance mass that should add is excessive, bring perhaps
Many other problems, to make compact conformation, sometimes added balanced structure quality needs are very big, even more than original matter of mechanism
Amount, can produce the larger counter-force of side effect in motion.Using this structure, the balance effect of toggle can not only be improved
Really, it is greatly lowered horizontal inertial force and vertical inertia force that frame is produced when running；And it is replaced by secter pat
In one group of driven gear, assembly precision and the requirement of driving gear and driven gear is greatly reduced, not only effectively improve work effect
Rate, and it is with low cost.
