Description
Technical field
The present invention relates to section rolling equipment, specifically a kind of shaft forgings three-high cross-wedge rolling mill, can be used for train shaft
The rolling of serial shaft forgings.
Background technology
Cross wedge rolling technique most occurred in Germany earlier than 1885.1961, Czechoslovakia first by this technique with
Equipment is used for commercial production.Subsequently, graceful (Redman) company of the Randt of Britain has introduced this technology, East Germany, Japan, Soviet Union etc.
Country also successively adopts this technique productions axial workpiece blank.Early in the 1950's, China begins to the spy of cross wedge rolling
Beg for and (introduced from network cross wedge rolling technique) with experimental work.But, research and the application of these cross wedge rolling techniques, great majority
Two roller cross wedge rolling technique researchs are confined to application.There is guide plate scratch, inside in the operation of rolling, easily in two roller cross wedge rolling machines
Loose, shaft member bends the defect such as serious.
Later, groups of people proposed three-roll-wedge transverse rolling technology；Beginning is also merely resting on theoretical shaping stage, without answering
In using actual production.Compared with two roller cross wedge rollings, advantage is three-roll-wedge transverse rolling：
1. axially flowing is easily realized；
2. rolled piece center portion stress state improvement；
3. the rarefaction defect that rolled piece center is likely to occur can be controlled preferably；
4. guide plate is eliminated, the defect that guide plate scratch rolled surface will not occur.
Because in three-roll-wedge transverse rolling, roll maximum outside diameter is limited by rolled piece minimum diameter, it may appear that three rolls are in maximum
Problem (the source collided outside diameter：Part roll forming technology》In April, 2010 publishes, chemical engineering industry publishing house, and chief editor is recklessly just
Extensive region).At present, three-high cross-wedge rolling mill maximum in the world is Φ 1060mm milling trains, accessory size can be processed for Φ 100mm ×
700mm, production efficiency is 6～10/min (sources：《Special rolling equipment》2014, Zhou Cun edited in metallurgical industry publishing house
Dragon etc.), it is impossible to meet processing major diameter, the demand of major axis shaft forgings.
The content of the invention
The drawbacks described above easily occurred in order to solve the two roller cross wedge rolling machine operations of rolling, and in order to meet major diameter,
The demand of major axis shaft forgings, it is an object of the invention to provide a kind of shaft forgings three-high cross-wedge rolling mill.
The purpose of the present invention is achieved through the following technical solutions：
The present invention include being separately mounted to power source in rolling-mill housing, reductor, three spindle balance casees, roll A, roll B,
Roll C and pneumatic hydraulic system, wherein power source are connected by drive mechanism with the reductor, and the outfan of the reductor leads to
Cross power transmission shaft B to be connected with the three spindle balances case input, the outfan of the three spindle balances case is by three power transmission shaft C difference
It is connected with roll A, roll B and roll C, drives roll A, roll B and roll C synchronization rotating Vortex；The roll A, roll B and
Line between the center of circle of roll C-terminal face is in equilateral triangle, and roll C is located at the lower section of roll A and roll B and opens vertically
There is splicing groove, bar to be rolled drives charging ram axial admission to roll A, roll B and roll C by the pneumatic hydraulic system
Between, the shaft forgings after roll A, roll B and roll C are rolled described in are placed in the splicing groove, turning with the roll C
Radius vector is to discharging.
Wherein：The axial-radial of the roll A, roll B and roll C is equivalently-sized, and the roll A is contour with roll B to be set
Put, and the sideline between the roll A end faces center of circle and the roll B end faces center of circle and plane-parallel；The roll A, roll B and roll
It is mounted on adjusting the arc-shaped gear of each roll radial direction on the power transmission shaft C of C；The bar is always positioned at roll A, roll B and roll C
Inscribe region, by the pattern on the roll A, roll B and roll C the shaft forgings are rolled into；The drive mechanism includes
Belt pulley, belt and power transmission shaft A, one end of power transmission shaft A is connected with the reductor, and the other end is connected with the belt pulley,
The outfan of the power source is connected by belt with belt pulley；The power source is pneumatic clutch, and the pneumatic clutch leads to
Cross belt to be connected with belt pulley, the roll A, roll B and roll C are often rotated one week, the pneumatic clutch is separated；The gas
Dynamic clutch is connected with air compressor air storage tank, and is provided with air compressor machine pressure gauge on the pipeline of connection.
Advantages of the present invention is with good effect：
1. the present invention is discharged using axial admission, radially, and three roll synchronization rotating Vortexes are rolled to bar, firmly
Uniformly, it is easier to realize axially flowing so that shaft forgings center portion stress state is improved, and can be controlled well in shaft forgings
The rarefaction defect that the heart is likely to occur.
2., present invention eliminates guide plate, it is to avoid the situation of guide plate scratch rolled surface occurs, environmental protection, noise are little.
3. the axial of three rolls of the present invention, radial dimension are consistent, and diameter can be adjusted, diameter of axle phase-adjustable, many wedge wedges
Enter, one-shot forming, water-cooled can be carried out using recirculated cooling water, production full process automatization degree is high, low cost.
