Description
Technical field
It the utility model is related to a kind of short stress bar rolling mill roller box installed and match somebody with somebody seal protection structure, belong to metallurgy industry bar
Short stress rolling mill roller case assembly equipment technical field.
Background technology
Short stress bar rolling mill is after using 2-3 or so, to ensure that the overall precision of milling train meets rolling line production requirement,
Need that whole milling train is carried out to disassemble maintenance and installation.
At present, in the assembling to short stress bar rolling mill roller case, because pull bar side is threaded button, roller case is being loaded
When, easily O-ring seal and dust ring are collided with crowded bad, O-ring seal and dust ring can only be re-replaced, and ressemble roller
Case, increase labor strength and spare parts cost, reduce operating efficiency.Even sometimes cause without bad seals are found
Operation in spite of illness after milling train overhaul, milling train can not be used because bad seals enter impurity locking, influence the normal work of milling train
Make.
Utility model content
The utility model purpose is to provide a kind of short stress bar rolling mill roller box installed and matches somebody with somebody seal protection structure, in assembling process
In, O-ring seal and dust ring can be protected, avoid sealing by extrusion damage of colliding with, solve to exist in background technology
The problem of.
The technical solution of the utility model is：
A kind of short stress bar rolling mill roller box installed matches somebody with somebody seal protection structure, comprising frame, pull bar, roller case, O-ring seal,
Dust ring and guide pin bushing, the guide pin bushing are hollow cylindrical structure, and one end of guide pin bushing is along the circumferential direction provided with chamfering, and pull bar is solid vertically
It is scheduled in frame, guide pin bushing is enclosed on the top of pull bar, and guide pin bushing is provided with one end of chamfering upper, and O-ring seal and dust ring are arranged on
The inner side of roller case, roller housing-case is on guide pin bushing.
The internal diameter of the guide pin bushing is engaged with pull bar, and the external diameter of guide pin bushing is engaged with roller case.
The angle of the chamfering of the guide pin bushing along the circumferential direction is 7 °
The top of the pull bar is provided with screw buckle.
The frame is fixed on rolling mill base.
Using the utility model, guide pin bushing is enclosed on the top of pull bar, and the screw buckle on pull bar is wrapped by guide pin bushing, mounted roller case
When, avoid the screw buckle on pull bar O-ring seal and dust ring are collided with it is crowded bad.After roller case is installed in place, by guide pin bushing from drawing
Bar top is gently extracted out, adjusts mounted roller case again afterwards.
The beneficial effects of the utility model are：During roller box installed is matched somebody with somebody, O-ring seal and dust ring can be protected
Come, avoid the bad seals caused by pull rod screw button collides with extruding, effectively improve the operating efficiency of milling train maintenance assembling, reduce
Labor strength and spare parts cost, extend milling train service life.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is enlarged drawing at the utility model A；
Fig. 3 is the utility model guide pin bushing front view；
Fig. 4 is the utility model guide pin bushing top view；
In figure：Frame 1, pull bar 2, roller case 3, O-ring seal 4, dust ring 5, guide pin bushing 6.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1-4, a kind of short stress bar rolling mill roller box installed matches somebody with somebody seal protection structure, includes frame 1, pull bar 2, roller
Case 3, O-ring seal 4, dust ring 5 and guide pin bushing 6, the guide pin bushing 6 are hollow cylindrical structure, and one end of guide pin bushing 1 is along the circumferential direction
Provided with chamfering, pull bar 2 is fixed in frame 1 vertically, and guide pin bushing 6 is enclosed on the top of pull bar 2, and guide pin bushing 6 is provided with one end of chamfering upper,
O-ring seal 4 and dust ring 5 are arranged on the inner side of roller case 3, and roller case 3 is enclosed on guide pin bushing 6.
In the present embodiment, the external diameter of guide pin bushing 6 is ∮ 115mm, and the internal diameter of guide pin bushing 6 is ∮ 110mm, and the length of guide pin bushing 6 is
290mm, the wall thickness 2.5mm of guide pin bushing 6.The chamfer angle of the one end of guide pin bushing 6 is 7 °, and chamfering length is 20mm；The other end of guide pin bushing 6 is without
Angle.The top of pull bar 2 is provided with screw buckle, and the middle part of pull bar 2 is provided with inclined-plane B.
Assembling process is as follows：
（1）Frame 1 is fixed on rolling mill base, the pull bar 2 matched is loaded in the bore hole of frame 1；
（2）Spacer ring, copper sheathing, flange and O-ring seal 4, dust ring 5 are installed on roller case 3；
（3）Guide pin bushing 6 is enclosed on to the top of pull bar 2, the one end of guide pin bushing 6 with chamfering is upper, while guide pin bushing 6 is using in pull bar 2
The inclined-plane B in portion blocks guide pin bushing 6, avoids the guide pin bushing 6 in assembling roller case 3 from sinking；
（4）Roller case 3 is sling, carried using the loading of its own weight slowly on the pull bar 2 of guide pin bushing 6, because of the screw thread of pull bar 2
Button is wrapped by guide pin bushing 6, now only should be noted that O-ring seal 4 and dust ring 5 are not when roller case 3 is just in contact with guide pin bushing 6
Mutually to be extruded with the end face of guide pin bushing 6；
（5）After roller case 3 is installed in place, guide pin bushing 6 is gently extracted out from the top of pull bar 2, adjusts mounted roller case 3 again afterwards.
