Description

A kind of changing rig of sizing mill

Technical field

The utility model relates to rolling machinery, particularly a kind of changing rig of sizing mill.

Background technology

Traditional changing rig as shown in Figure 1, 2, by roll change buggy 01, rail set 02, dolly transmission 03, push cylinder 4, oil cylinder supporting base 05, push-and-pull crossbeam 06, cut somebody's hair 7, drag hook 8, roll stand 9 and main engine bed 10 form.Roll change process is: roll change buggy 01 is moved to roll change position in the driving of dolly transmission 03; After oil cylinder 4 drives push-and-pull crossbeam 06 by drag hook 8, the roll stand 9 of main engine bed 10 inside to be moved on roll change buggy, dolly continues to move ahead and stops at new frame roll change position, until oil cylinder 4, drives push-and-pull crossbeams 06 7 to complete roll change process after the new roll stand 9 on roll change buggy is pushed to main engine bed 10 by cutting somebody's hair.Traditional changing rig floor space is large, and number of devices is many, and cost of investment is high.

Utility model content

The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of changing rig of sizing mill is provided, and solves traditional changing rig parts many, and floor space is large, the technical problem that cost of investment is high.

The utility model is achieved through the following technical solutions:

A kind of changing rig of sizing mill, comprise: push cylinder, cut somebody's hair, drag hook, roll stand and main engine bed, it is characterized in that: two described push cylinder are built in respectively the left and right sides of main engine bed, on the moving piston bar of push cylinder, be provided with push-and-pull connector, by plate, push-and-pull connector is fixed and is connected on sliding beam, on sliding beam, be provided with chute, chute is buckled on slide plate, on sliding beam, be provided with sleeve and slot, slide plate is arranged on roll change stand, roll change stand is bolted on stand base, on sliding beam, be also provided with a plurality of cutting somebody's hair and a plurality of drag hooks.

The cylinder end flange of described push cylinder is bolted on main engine bed, is also provided with the vulcanie pad of two and half flanges and assurance oil cylinder direct dimension at oil cylinder end.

The utility model compared with prior art, because roll change oil cylinder is installed on sizing stand of main engine seat inside, has been removed original roll change buggy, dolly transmission and rail set, greatly reduces weight of equipment, floor space and cost of investment; Meanwhile, owing to having removed foundation construction comparatively dolly transmission and the rail set of difficulty, also greatly reduce Equipment Foundations construction cost.

The utility model, for sizing mill, has parts few, and floor space is little, the advantage that cost of investment is low.

The specific embodiment

As shown in Fig. 3～9, a kind of changing rig of sizing mill, comprise: push cylinder 4, cut somebody's hair 7, drag hook 8, roll stand 9 and main engine bed 10, two described push cylinder 4 are built in respectively the left and right sides of main engine bed 10, on the moving piston bar of push cylinder 4, be provided with push-and-pull connector 5, by plate 6, push-and-pull connector 5 is fixed and is connected on sliding beam 3, make the stretching motion of push cylinder 4 drive sliding beam 3 front and back to slide; On sliding beam 3, be provided with chute 31, chute 31 is buckled on slide plate 11, the guiding mechanism moving as roll stand 9 when roll change; On sliding beam 3, be provided with sleeve 32 and slot, slide plate 11 is arranged on roll change stand 1, roll change stand 1 is bolted on stand base 2, is also provided with a plurality ofly to cut somebody's hair 7 and a plurality of drag hook 8 on sliding beam 3, pushes and pull out the executive component of main engine bed 10 as roll stand 9.

In order to guarantee that oil cylinder is installed and the linearity of oil cylinder inner piston rod motion, cylinder end flange is bolted on main engine bed 10, is also provided with the vulcanie pad 42 of two and half flanges 41 and assurance oil cylinder direct dimension at oil cylinder end.

In order to guarantee the clean of push cylinder 4 piston rods, piston rod zero-bit in retraction all the time when not roll change.While needing roll change, piston rod just stretches out.

The utility model roll change process is as follows:

1, push cylinder 4 piston rods stretch out, and make connected push-and-pull connector 5 extend into sleeve 32 inside on sliding beam 3;

2, insert plate 6, complete the connection of push cylinder 4 and sliding beam 3;

3, push cylinder 4 retractions, drive sliding beam 3 close to the roll stand 9 of main engine bed 10 inside, and arrival stops behind roll change position;

4, manually the drag hook on sliding beam 38 is transferred, it is connected with the drag hook on roll stand 9;

5, push cylinder 4 is stretched out, and drives sliding beam 3 to pull roll stand 9 to pull out main engine bed 10;

6, with driving, the old roll stand of pulling out is called away, and hung on new roll stand 9;

7, push cylinder 4 retractions, drive sliding beam 3 to push main engine bed 10 inside by 7 roll stands 9 of cutting somebody's hair, and after putting in place, stop;
