Description
Technical field
The present invention relates to the technical field of cold pilger mill, especially a kind of high speed and the guarantee frame stable cold rolled tube of running
The new driving structure of machine.
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.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided a kind of high speed and guarantee frame
Operate the new driving structure of stable cold pilger mill.
The technical solution adopted for the present invention to solve the technical problems is：A kind of new driving structure of cold pilger mill, drives
Motivation frame high-speed motion, the drive mechanism includes high speed shaft, and the two ends of the high speed shaft are respectively provided with a high gear, described
High gear is engaged with crank shaft gear wheel, and the opposite side of the crank shaft gear wheel is engaged with balance shaft gear wheel, crank shaft
Gear wheel is arranged on crank shaft, and coaxial crank shaft balancing weight, crank throw are provided with the inside of the crank shaft gear wheel
The tip of the axis is provided with connecting plate, and one end of the connecting plate is secter pat, and the other end of connecting plate has parallel to crank shaft
Crank throw bearing pin, be provided with the crank throw bearing pin and drive frame to make the connecting rod of linear reciprocating motion；The balance shaft gear wheel
In balance shaft, balance shaft balancing weight, balance the tip of the axis peace are installed in the balance shaft, on the inside of balance shaft gear wheel
Equipped with counterweight block.
Further, the both sides of the drive mechanism are provided with the gear housing of enclosed construction.Gear housing is tied for closing
Structure, it is possible to achieve rolling mill practice oil is separated with gear lubricant.
Further, the crank shaft gear wheel and balance shaft gear wheel are eccentric gear.
Further, the crank shaft balancing weight, balance shaft balancing weight and balance balancing weight are fan-shaped block structure.
Further, the rotation direction of the crank shaft balancing weight and balance shaft balancing weight is conversely, and when crank shaft is matched somebody with somebody
When the scallop of pouring weight moves to bottom, the scallop of balance shaft balancing weight is located at topmost.
The beneficial effects of the invention are as follows：Manufacturing cost and use cost of the present invention is all relatively low, and good balance effect substantially increases life
Efficiency is produced, Maintenance and Repair are convenient, and the cold pilger mill speed of service of LG-25 models is promoted to 860m/s from original 700m/s, and
Can guarantee that frame is still steady.

Specific embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further illustrated.These accompanying drawings are simplified signal
Figure, only illustrates basic structure of the invention in a schematic way, therefore it only shows the composition relevant with the present invention.
A kind of new driving structure of cold pilger mill as shown in Figure 1, drives frame high-speed motion, and drive mechanism includes height
Fast axle 1, the two ends of high speed shaft 1 are respectively provided with a high gear 2, and high gear 2 is engaged with crank shaft gear wheel 3, and crank shaft is big
The opposite side of gear 3 is engaged with balance shaft gear wheel 5, and crank shaft gear wheel 3 is arranged on crank shaft 11, crank shaft gear wheel 3
Inner side coaxial crank shaft balancing weight 4 is installed, the end of crank shaft 11 is provided with contiguous block 10, the one of contiguous block 10
It is secter pat to hold, and the other end of contiguous block 10 has the crank throw bearing pin 12 parallel to crank shaft 11, is provided with crank throw bearing pin 12
Frame is driven to make the connecting rod 8 of linear reciprocating motion；Balance shaft gear wheel 5 be arranged on balance shaft 9 on, in balance shaft 9, balance shaft it is big
The inner side of gear 5 is provided with balance shaft balancing weight 6, and the end of balance shaft 9 is provided with counterweight block 7.
Wherein, crank shaft gear wheel 3 and balance shaft gear wheel 5 are eccentric gear.Crank shaft balancing weight 4, balance shaft is matched somebody with somebody
Pouring weight 6 and balance balancing weight 7 are fan-shaped block structure.As shown in figures 2-3, crank shaft balancing weight 4 and balance shaft balancing weight 6
Rotation direction conversely, and when the scallop of crank shaft balancing weight 4 moves to bottom, the scallop of balance shaft balancing weight 6 position
In topmost, vice versa, and the weighting power of vertical direction is balanced with this；Crank shaft balancing weight 4 is coaxial with contiguous block 10, balance
Axle balancing weight 6 is coaxial with counterweight block 7, so when the scallop of contiguous block 10 moves to bottom, counterweight block 7
Scallop is located at topmost.
Can be very big due to setting one piece of balance weight volume on crank shaft 11 and balance shaft 9, so crank shaft 11 and balance shaft 9
Upper difference is each to set two pieces of balancing weights, whole drive mechanism equivalent to eight pieces of balancing weights are provided with, well in the horizontal direction and
Vertical direction balance inertial force, and balancing weight production, manufacture are simply, can effectively control cost, are applicable to large, medium and small type
Cold pilger mill.
