Abstract
The utility model belongs to the metallurgy technical field, and provides a variable speed suspension arm dual roller cold rolling mill which can adjust the rotating speed of roller according to the demand, and the roller wheel of the variable speed suspension arm dual roller can be disassembled and replaced, the power passes through the two constant speed reverse output shafts and a joint slack, drives two roller which support on a thick and a thin roller seat, and makes a pair of rollers arranged on the roller axle head outside the thick roller seat reversely rolled to perform the cold roll. The rolling speed of the roller can be changed according to the demand by turning the speed transmission handle on a transmission case; only the bolt and the clamping plate need to be disassembled when the roller wheel is thinned or replaced.
Description
The utility model belongs to metallurgical technology field.
At present, the known pair of cold mill be by motor through belt transmission to decelerator, drive a pair of gear by the output shaft of decelerator again and drive two rolls through shaft coupling, roll wheels places the centre of two bearings, rectangular shaft bearing and the roller base of back up roll, is gantry frame type and arranges.The weak point of existing cold-rolling mill is: 1, roll rotational speed is constant, can not carry out speed change with cold rolling gauge or diameter of wire different needs change moment; 2, roll wheels places in the middle of the portal frame, though rigidity is good, but want the roll wheels of reconditioning or replacing rapid wear, necessary often parts such as dismounting rectangular shaft bearing, bearing, not only time-consuming, also very easily damage bearing, destroy the fit clearance of roll and bearing, bearing and rectangular shaft bearing, influence the operate as normal and the service life of cold-rolling mill.
The purpose of this utility model provides a kind ofly can adjust roll rotational speed and the two cold mills of the convenient speed change cantilever that changes roll wheels immediately as required.
The purpose of this utility model be achieved in that power by motor through belt transmission to gearbox, again by the reverse output shaft of two constant speed of gearbox through shaft coupling, drive an end bearing in thin roller base, the other end is supported on a pair roller of thick roller base, make a pair roller wheel constant speed that is contained in thick roller base outside roll spindle nose to rolling, implement cold rolling.When adjusting roll rotational speed when cold rolling gauge or diameter of wire different needs change moment, the gear change hand lever of pulling on the gearbox can be realized.Want reconditioning or change roll wheels, only need the bolt and the pressing plate of dismounting roll axle head.
Owing to adopt such scheme, can realize changing as required roll rotational speed immediately, easy, fast change roll wheels, guarantee the optimum Working and the service life of cold-rolling mill, and improved its operating efficiency.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a structural front view of the present utility model.
Fig. 2 be the A of Fig. 1 to view, show the radial structure of cold-rolling mill.
Among the figure, 1. rolling mill base, 2. roll wheels, 3. pressing plate, 4. bolt, 5. roll, 6. key, 7. bearing cap, 8. thick rectangular shaft bearing, 9. big adjusting screw(rod) seat, 10. big adjusting screw(rod) lid, 11. big adjusting screw(rod)s, 12. big wrenching bar, 13. big jack panel, 14. thick roller bases, 15. press strips pieced together, 16. the axial restraint double-screw bolt, 17. double-row bearings, 18. back-up rings, 19. piece together tight nut, 20. nuts, 21. small wrench bars, 22. the minor adjustment screw rod, 23. little assembly jack panels, 24. thin roller bases, 25. the minor adjustment screw bolt seat, 26. minor adjustment screw rods lid, 27. thin rectangular shape bearing blocks, 28. single-row bearing, 29. bearing caps, 30. shaft couplings, 31. output shaft, 32. gearboxes, 33. gear change hand levers, 34. big belt pulley, 35. V-belts, 36. power shafts, 37. small belt pulley, 38. motor shafts, 39. motor.
Among Fig. 1, on rolling mill base (1), device gearbox (32) and the stressed size of roll two supporting-points is determined when cold rolling thin roller base (24), thick roller base (14), gearbox (32) has upper and lower two output shafts (31), connect with two shaft couplings (30) respectively, the other end of two shaft couplings (30) connects with identical two rolls (5) respectively.Roll (5) is loaded in the thin rectangular shape bearing block (27) with single-row bearing (28) in thin roller base (24), makes axial restraint with bearing cap (29); In thick roller base (14), be loaded in the thick rectangular shaft bearing (8) with double-row bearing (17), with bearing cap (7) and back-up ring (18), piece together tight nut (19) and make axial restraint.Be spun on the minor adjustment screw rod (22) of thin roller base (24) top, pack into and be fixed on after thin rectangular shape bearing block (27) goes up minor adjustment screw bolt seat (25), the minor adjustment of closing screw rod lid (26), little assembly jack panel (23) and small wrench bar (21) are equipped with in minor adjustment screw rod (22) upper end.Equally, be spun on the big adjusting screw(rod) (11) of thick roller base (14) top, packing into is fixed on after thick rectangular shaft bearing (8) goes up big adjusting screw(rod) seat (9), the big adjusting screw(rod) lid (10) that closes, and big assembly jack panel (13) and wrenching bar (12) greatly are equipped with in big adjusting screw(rod) (11) upper end.Thin, thick roller base (24), (14) are continuous with two axial restraint double-screw bolts (16), tighten up with nut (20).The spindle nose of the roll (5) outside thick roller base (14) is inserted in roll wheels (2), connects with key (6), and is fixing with pressing plate (3) and bolt (4).
Power reaches gearbox (32) by motor (39) through motor shaft (38), small belt pulley (37), V-belt (35), big belt pulley (34), power shaft (36), reach a pair roller (5), drive roll wheels (2) through shaft coupling (30) by two output shafts (31), implement cold rolling rolling.Pull the gear change hand lever (33) on the gearbox, the change roll rotational speed.Unscrew large and small assembly jack panel (13), (23), the synchronous large and small wrenching bar of switching (12), (21), make large and small adjusting screw(rod) (11), (22) rotation, driving thick, thin rectangular shape bearing block (8), (27) rises or falls, make the topping roll lifting, bottom roll is motionless, and the crack changes thereupon between the roll wheels.After mixing up the gap, screw large and small assembly jack panel (13), (23).Remove wrenching bar and piece together jack panel, on adjusting screw(rod), adorn motor, adjust crack between the roll wheels but electricity consumption drives.
From Fig. 2, thick, thin roller base (14), (24) are frame-types, in the both sides of separately both ends of the surface, press strip (15) are housed all, make thick, thin rectangular shape bearing block (8), (27) axial location thereon.
