Specific embodiment
Below in conjunction with attached drawing, by example, the invention will be further described.
Referring to attached drawing 1-3, a kind of eccentric press down mechanism of universal mill, comprising horizontal roller, edger roll, horizontal roller bearing block,
Edger roll support base 4, column 5, horizontal roller screwdown gear 6 and vertical roller side screwdown gear 7, horizontal roller and edger roll are mounted on a rack
On, horizontal roller bearing block and edger roll support base 4 are fastenedly connected by column 5, and the horizontal roller includes upper roller 1 and lower roll 2, described
Edger roll include left edger roll 8 and right edger roll 3, upper roller 1, lower roll 2 and left edger roll 8, right edger roll 3 axis in a vertical plane, institute
Upper roller 1 is stated equipped with horizontal roller screwdown gear 6, left edger roll 8 and right edger roll 3 are respectively equipped with the identical vertical roller side screwdown gear 7 of structure,
The horizontal roller screwdown gear 6 includes press down motor 11, turbine worm reducers 12, secondary worm screw 13, a secondary turbines 14
With eccentric bushing 15,1 both ends of upper roller are fixed in eccentric bushing 15, and eccentric bushing 15 is fixed secondary in bearing block on eccentric bushing 15
Turbine 14, secondary turbine 14 are drivingly connected by secondary worm screw 13 and a turbine worm reducer 12 and motor 11, described vertical
Roller side screwdown gear 7 includes ball ring 22, adjusting screw 23, worm screw 26 and hydraulic cylinder 28, and one end of adjusting screw 23 passes through snail
Bar 26 and hydraulic cylinder 28 are drivingly connected, and the other end of adjusting screw 23 is connected by ball ring 22 and the edger roll cabinet equipped with edger roll
It connects.
In the present embodiment, horizontal roller is all made of high-carbon chrome-nickel cast steel composite centrifugal with edger roll and casts, roll surface
Hardness HS=60 ± 3, roll surface difference of hardness < 2HS use layer hardness drop < 5HS.Horizontal roller is fabricated structure, by collars with
Roll shaft hot charging forms, and roll shaft can repeatedly use.The radial force of horizontal roller is born by four-line column roller bearing, axial force
It is born by the tapered roller thrust bearing of fore side, edger roll uses biserial circular cone roller bearing.
Referring to attached drawing 2, horizontal roller screwdown gear is started by press down motor 11, passes through 12 band of worm type of reduction gearing
It moves secondary worm screw 13 to rotate, so that the secondary worm gear 14 being fixed on eccentric bushing 15 be made to rotate, passes through the eccentricity of eccentric bushing 15
To determine the center of upper roller 1 and lower roll 2 away from the distance of pressure, which is detected by encoder, to be determined.
Referring to attached drawing 4, horizontal roller axial adjusting device, upper roller 1 can carry out axially adjustable, and axially adjustable amount is ± 5mm, is adopted
With hydraulic motor driving method.Horizontal roller axial adjusting device is mounted on milling train operation side shaft holder, above and below universal mill
