Abstract
The utility model relates to a coupling of a hydraulic quick dismounting rolling mill, which relates to the field of mechanical equipment for steel pressed work, comprising a wedge gripping mechanism, a bidirectional hydraulic cylinder, a gripping and locking mechanism and a short shaft. The utility model is especially suitable for the use under the condition of frequent roll changing of a rolling mill. The utility model has the advantages of convenient assembly and disassembly, less abrasion and stable operation.
Description
The utility model belongs to iron and steel pressure processing machinery field.
At present, shape rolling mill main transmission spindle major part is continued to use plum-blossom sleeve socket joint axle or universal-joint-pin type universal connects a form.Between each part of plum-blossom sleeve socket joint axle and connect axle and roll be connected fit clearance very big (6～15mm), the force part is dry friction, serious wear, cause thus: rolled piece has intense impact load in rolled piece moment of nipping, not only be prone to accidents, and the roll rotational speed instantaneous mutation, make rolling parameter produce unfavorable variation; Have larger axis to be used for roll and uni-drive gear box to masterpiece when connecing thrust load, make the roll axial float, the rolled piece quality descends, and main transmission equipment is subjected to axial impact, connects a running noise height; Universal-joint-pin type universal connects axle superior function on transmission of power, but usually simple sleeve type is little with roll type of attachment gap, the shape and size precision of breaker roll end requires high, dismounting is time-consuming during roll change, can not adapt to the frequent working condition of shaped steel mill roll, as amplify the gap, then still there is the defective of plum-blossom sleeve socket joint axle.
The purpose of this utility model is the type of attachment that is to design a kind of easy accessibility and does not have the excessive defective in gap, has the milling train main transmission spindle shaft coupling that clamps function.
The utility model is following finishing:
Hydraulic pressure fast assembling-disassembling milling train shaft coupling, it comprises oblique-wedge clamping system, two-way hydraulic cylinder, the clamping force locking mechanism, minor axis (11), port connection (12), oblique-wedge clamping system are made up of wedge body (4), wedge (5) and straight pin (13), wedge (5) has groove, opens tail straight pin (13) and is fixed on the wedge body (4), and stretch in the groove of wedge (5); Two-way hydraulic cylinder is made up of piston (8), cylinder body (9), annular oil groove (17), has oilhole (15) in the piston (8), and the clamping force locking mechanism is made up of the screw thread of locking nut (6) and piston (8) rod.
Minor axis (11) is the carrier and the part of said mechanism, has sealing annular oil groove (17) and the oilhole (16) that communicates with it above, and communicates with oilhole (15) in the piston (8).
Wedge in the oblique-wedge clamping system (5) is arranged for axial symmetry, is synchronously entad clamping.
Port connection (12) position on the minor axis (11) is on same end face.
Shaft coupling clamping back and roll do not have relative motion for being rigidly connected during work, therefore, the shaft coupling wearing and tearing are very little, long service life.In addition, owing to considered not change the end shape that is connected roll in the design of moment of torsion transfer components, make shaft coupling similar cover socket joint axle when unclamping, meet workman's roller replacing operation custom, it is short that the workman adapts to the process of grasping the hydraulic clamp shaft coupling, in the actual production, frame only needs disengaging that a people can successfully operate hydraulic clamp shaft coupling and roll rapidly and is connected during roll change.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model front view,
(1) is pad among the figure, and (2) are back-up ring, and (3) are dirt-proof boot, (4) be the wedge body, (5) are wedge, and (6) are locking nut, (7) be the O RunddichtringO, (8) be piston, (9) are cylinder body, and (10) are the O RunddichtringO, (11) be minor axis, (12) be quick port connection, (15), (16) are oilhole, and (17) are the sealing annular oil groove.
Fig. 2 is the A-A cutaway view of the utility model left view and left view
(13) for opening the tail straight pin, (14) are the course of work of key hydraulic pressure fast assembling-disassembling milling train shaft coupling among the figure:
At first pressure oil enters A chamber in the oil cylinder through quick port connection (12) a, hold out against piston (8), this moment locking nut (6) unclamped and left the pine foot (hold out against piston (8) as earlier not advancing pressure oil to the A chamber, locking nut (6) is difficult to unclamp), commutate by reversal valve then, pressure oil is through quick port connection (12) b, oilhole (16) is by the sealing annular oil groove (17) of minor axis (11), oilhole (15) from piston (8) enters B chamber the oil cylinder, move right to promote piston (8), drive the wedge body (4) that is threaded with piston (8) and open tail straight pin (13),, wedge (5) is promoted by the interaction of straight pin (13) with inclined-plane C, so far be releasing orientation, can easily shaft coupling be separated with roll, remove connection, carry out roller replacing operation.
After roll change finishes, with shaft coupling suit topping roll end, cut-in pressure oil enters A chamber in the oil cylinder through quick tubing head (12) a, promotes piston (8) and wedge body (4) and is moved to the left, wedge (5) is pressed on the cylindrical of roll end, realizes clamping connection.At this moment, locking nut (6) is screwed to the right, near cylinder body (9), so far for clamping duty, pressure oil gets final product off-load and oil pipe is withdrawn.
This shaft coupling has been applied to our factory's milling train, and in production run, the roll running is steadily impacted and greatly weakened, product quality improves, and production accident has reduced 40%, has improved operating rate of rolling mill, can create 500,000 yuan/year of the output values more, after measured, extension shaft for rolling mill running noise decline 20dB(A).
