Wherein: 1. roll; 2. emery wheel; 3. bistrique expansion bend; 4. driving support seat; 5 motor mounting plates; 6. drive motors; 7. screw mandrel; 8. pressing plate; 9. pull bar; 10. spring; 11. cross slide seat; 12. slip pole; 13. hold-down support; 14. installation base frame; 15. flat body nut; 16. rolling-mill housing; 17. grinding wheel spindle sleeve; 18. rolling bearing; 19. circlip; Connect cover 20. float; 21. anticreep plate; 22. key cover; 23. joint bolt; 24. set bolt; 25. spider; 26. holding screw; 27. grinding wheel spindle; 28. rolling bearing; 29. end cap; 30. mounting screw; 31. shelves bar
The two ends of the screw mandrel of traversing structure (7) are by hold-down support (13) supporting, and hold-down support (13) is fixed tightly in nut and installs on the base frame (14), base frame (14) is installed is fixed on the rolling-mill housing (16) with nut.Screw mandrel (7) passes through the reduction gearing transmission by direct current generator.
Internal thread on the driving support seat of grinding mechanism (4) cooperates with screw mandrel (7), can make the rotation of screw mandrel (7) become grinding mechanism and move axially along roll (1).Motor mounting plate (5) and pressing plate (8) connect with driving support seat (4) with bolt.Drive motors (6) is installed on the motor mounting plate (5) with set bolt (24).Bistrique expansion bend (3) is welded on the driving support seat (4), can be used to regulate the axial location of emery wheel (2).Emery wheel (2) is a bowl type emery grinding wheel, the axis normal of emery wheel (2) its axis and roll (1) when work, and its front end grinding face and roll (1) roll surface are tangent, and both contacts wire are positioned at emery wheel (2) front end downside.
One end of the grinding wheel spindle (27) in the bistrique expansion bend (3) is screwed emery wheel (2), grinding wheel spindle (27) is bearing in rolling bearing (18) and (28) lining, rolling bearing (18) and (28) are contained in grinding wheel spindle sleeve (17) lining, use end cap (29) and circlip (19) to fix its axial location respectively.Grinding wheel spindle sleeve (17) is contained in the spider (25), cooperates with its formation activity.Spider is processed with strip through-hole on (25), and grinding wheel spindle has screw on (27), and holding screw (26) passes through hole and connects with screw on the grinding wheel spindle (27), is used for fixing the axial location between grinding wheel spindle sleeve (17) and spider (25).Spider (25) is welded on the driving support seat (4).Anticreep plate (21) is screwed the output shaft front end at drive motors (6).Drive motors (6) axle is used key connecting with key cover (22), key cover (22) is fixed on to float with joint bolt (23) and connects cover (20) one ends, the other end that connects cover (20) that floats is processed into splined hole, and the respective end of grinding wheel spindle (27) is processed into the splined shaft that cooperates with splined hole, forms axially adjustable torque transmission mechanism.
Slip pole (12) two ends of hold-down mechanism, the same with screw mandrel (7), also by hold-down support (13) supporting, cross slide seat (11) is enclosed within on the slip pole (12), and its another through hole inserts pull bar (9).One end of pull bar (9) is processed into handwheel, and the side cover upper spring (10) of handwheel is arranged, and the other end of pull bar (9) is processed with screw thread, is connected with flat body nut (15).The flange of flat body nut (15) is pressed on the pressing plate (8), and groove is arranged at pressing plate (8) top, and the flat body of groove side and flat body nut (15) partly forms and is slidingly matched.The upper end of pressing plate (8) fixedly blend stop (31) of mounting screw (30).Flat body nut (15) can transmit spring (10) and produce pressure.Handwheel adjustable pressure size.Pressing plate (8) is connected as spring compression mechanism and wheel grinding mechanism, both can transmit grinding pressure, can drive hold-down mechanism again and move laterally along slip pole (12).
In process of production, when repairing, can start the direct current generator of transverse-moving mechanism earlier, make bistrique move to the original position of an end at the roll surface position that needs reconditioning as the roll shape of need breaker roll (1) or wearing and tearing roll surface.Regulate bistrique expansion bend (3) then, make emery wheel (2) reach suitable grinding position.The handwheel of adjusting yoke (9) applies certain grinding pressure again.Start milling train master motor with that simultaneously, laterally the direct current generator that moves and the drive motors (6) of emery wheel (2) carry out reconditioning to the certain position of roll surface.Reconditioning finishes, and all motors of stop loosen spring (10) with handwheel, uses bistrique expansion bend (3) that emery wheel (2) is moved apart roll (1) again.
Use this arrangement for grinding, can make cold strip rolling mill need not unload roller, selectively online reconditioning is carried out at the certain position of the body of roll, improve the product strip shape quality, prolong the effect of roll changing period thereby obtain with various mill speeds and different roller surface hardness.This apparatus structure is simple, and is easy to process, and small investment has desirable grinding capacity.Roller surface quality after the reconditioning satisfies instructions for use.
