Description
Technical field
This utility model is related to a kind of additional equilibrium device, particularly a kind of rack of cold pipe mill double-sector block balance dress
Put.
Background technology
The impulse stroke of current rack of cold pipe mill is to be come by the slider-crank mechanism that bent axle rotarily drives connecting rod mostly
Complete the reciprocating motion of frame.Cold pilger mill when running up, for reciprocating frame 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 moment can cause the strong vibration of cold pilger mill and noise, the abrasion of aggravation parts
And fatigue failure, the kinematic accuracy of reducing mechanism and robust motion.The technical measures adopting at present have：(1) flywheel energy storage delays
Flushing device, complex structure, manufacturing cost is high；(2) also vertical links is adopted to drive in addition to adding eccentric mass on bent axle another
Slide block in set vertical direction is balancing；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) to be balanced using one or more planetary mechanisms, counterbalance effect
Very good, but complex structure, and installation difficulty is big；(4) adopt balance weight horizontal arrangement, by two sets of sides of Bevel Gear Transmission operating
To contrary balance system, its structure is also more complicated.
Utility model content
This utility model is directed to prior art deficiency, provides a kind of rack of cold pipe mill double-sector block bascule, makes cold
Pipe mill stably and normally operates under high-speed condition, reduces vibration and the noise of equipment, and improves its service behaviour, protects simultaneously
Hold the compact of cold pilger mill structure.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals：A kind of cold pilger mill
Frame double-sector block bascule, including two groups of frames being placed in parallel, connecting rod, driven gear and driving gear, described driven
Gear includes balance gear (4) and crank gear, and described connecting rod is connected with crank gear, and described balance gear and crank gear are nibbled
Close, described balance gear and described crank gear are provided with fan-shaped balance weight, described balance gear and crank gear set
It is equipped with fan-shaped chamber, fan-shaped chamber can reduce added fan-shaped balance weight quality, not only contribute to reduce moment of inertia, and can keep
The compactedness of structure；The quality of fan-shaped balance weight is to be calculated with the quality of connecting rod and throw of crankshaft by frame, different
The frame of quality needs different fan-shaped balance weight quality to coordinate from connecting rod and throw of crankshaft, in residual inertia force maximum
Balance weight optimum balance quality is chosen, sometimes for simplified processing process, balance gear and crank gear in minimum optimization aim
On can also be not provided with fan-shaped chamber.
It is preferred that described balance gear and described crank gear have the number of teeth and the modulus of identical in such scheme, with
Just more preferable transmission efficiency and degree of engagement are obtained.
It is preferred that being provided with bolt hole on described sector balance weight in such scheme.
It is preferred that described balance gear and crank gear are bolt and pin connection with fan-shaped balance weight in such scheme
Connect, processing is convenient.
It is preferred that described sector balance weight is arranged at described balance gear and described crank gear in such scheme
Inner side.
In such scheme it is preferred that described sector balance weight internal diameter R be more than frame top chock full-size H it is ensured that
Cold pilger mill structure compact.
It is preferred that fan-shaped balance weight on fan-shaped balance weight on described crank gear and balance gear in such scheme
Phase contrast is 180 degree.
This 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, even if in theory can be with complete equipilibrium, but the balance mass due to adding be excessive, brings perhaps
Many other problems, for making compact conformation, sometimes added balanced structure quality needs very big, even more than original matter of mechanism
Amount, can have side effects in motion larger counter-force, using this structure, after biparting shape single order balance, produces when frame is run
Raw horizontal inertial force and vertical inertia force are greatly lowered, thus reducing this power and cold pilger mill that moment causes is strong
Strong vibration and noise, improve abrasion and the fatigue failure of parts, improve kinematic accuracy and the robust motion of mechanism, protect simultaneously
Hold the compact of cold pilger mill structure, and this bascule be simple to manufacture, compact conformation, low cost.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the top view of this utility model embodiment.
Fig. 3 is this utility model fan-shaped chamber structural representation.
Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings：Referring to figs. 1 to Fig. 3 institute
Show, a kind of rack of cold pipe mill double-sector block bascule, including two groups of frames being placed in parallel 1, connecting rod 2, driven gear and
Driving gear 3, described driven gear includes balance gear 4 and crank gear 5, and described connecting rod 2 is connected with crank gear 5, described
Balance gear 4 is engaged with crank gear 5, and described balance gear 4 and described crank gear 5 are provided with fan-shaped balance weight 6, institute
State and be provided with fan-shaped chamber 7 on balance gear 4 and crank gear 5；Described balance gear 4 and described crank gear 5 have identical
The number of teeth and modulus, described sector balance weight 6 is provided with bolt hole, described balance gear 4 and crank gear 5 and fan-shaped balance
The connected mode of block 6 is bolt and pin connection, and described sector balance weight 6 is arranged at described balance gear 4 and described song
The inner side of handle gear 5, described sector balance weight 6 internal diameter R is more than full-size H of frame top chock, on described crank gear 5
Fan-shaped balance weight 6 be 180 degree with fan-shaped balance weight 6 phase contrast on balance gear 4.
For making compact conformation, sometimes added balanced structure quality needs very big, the even greater than initial quality of mechanism, fortune
Disorder of internal organs can have side effects larger counter-force, described balance gear 4 and crank gear 5 arranges described fan-shaped chamber 7, it is possible to decrease institute
Plus balance mass, not only contribute to reduce moment of inertia, and both compactedness can be kept；Mechanism inertia force completely flat
Weighing apparatus is difficult to realize for slider-crank mechanism, even if in theory can be with complete equipilibrium, but the balance mass mistake due to adding
Greatly, bring many other problems, thus complete equipilibrium method should not be adopted, by setting fan on balance gear 4 with crank gear 5
Shape chamber 7, and the fan-shaped balance weight 6 of setting above balance gear 4 with crank gear 5, can reduce barycenter acceleration and angle accelerates
Periodically variable inertia force and moment of inertia that degree produces, thus reduce this inertia force and cold pilger mill that moment causes is strong
Strong vibration and noise, same type and its vibrating noise are more than 80 decibels, and after this structure, the vibration noise of cold pilger mill is
Less than 60 decibels.And it is greatly improved the speed of service of cold pilger mill, improve pipe production efficiency.
Protection domain of the present utility model includes but is not limited to embodiment of above, and protection domain of the present utility model is to weigh
Sharp claim is defined, and any replacement that those skilled in the art that this technology is made is readily apparent that, deformation, improvement each fall within
Protection domain of the present utility model.
