Description

A kind of method for designing and device that is used for the side direction roll change mechanism of double-roller cold pilger mill

Technical field

The invention belongs to field of metallurgical equipment, as a kind of process equipment of metal tube rod, particularly a kind of method for designing and device that is used for the side direction roll change mechanism of double-roller cold pilger mill.

Background technology

Cold pilger mill adopts open top roll housing more in the prior art, for open top roll housing, should at first the loam cake of support be opened before the roll change, directly old roll is called away with crane then, used the same method then new roll is changed, build loam cake with steel wire rope, promptly finish roll change, this roll-changing method spended time is long, and inefficiency is unfavorable for realizing high-speed rolling.For closed frame, frame integral body is closed, and loam cake can't be dismantled.

Summary of the invention

The purpose of this invention is to provide a kind of method for designing and device that is used for the side direction roll change mechanism of double-roller cold pilger mill that a kind of simple in structure, roll change is convenient fast, can enhance productivity.

Technical scheme of the present invention is: design a kind of method for designing and device that is used for the side direction roll change mechanism of double-roller cold pilger mill, it is characterized in that: the side direction roll change mechanism that is used for double-roller cold pilger mill comprises push-pull device at fixed and roll change buggy at least, roll change buggy is movably connected in track by slide rail and track and slides, the slide plate that roll change buggy has two vertical tracks to move, two slide plates respectively are that independently moving body is vertical with track mobile under the effect of mobile drive deivce; Two one on slide plates are used to place old roll, and another is used to place new roll; Push-pull device at fixed is used for releasing old roll that cold pilger mill changes a room slide plate to roll change buggy, is used for pulling out slide plate of roll change buggy and places new roll in cold pilger mill; The course of work of the present invention is: roll change buggy is placed new roll on a slide plate, and the slide rail of roll change buggy moves to the old roll location that needs replacing in the cold pilger mill along track; The empty slide plate of roll change buggy shifts out to cold pilger mill and puts in place, the old roll that needs to change in the screw mandrel release cold pilger mill of push-pull device at fixed is to the empty slide plate of roll change buggy, be recovered on the empty slide plate of roll change buggy, the slide rail of roll change buggy moves along track once more, and the slide plate that another that makes roll change buggy is equipped with new roll needs the position changed in the cold pilger mill; The screw mandrel of push-pull device at fixed is pulled out in the slide plate new roll and is needed the old roll location changed in the cold pilger mill, and the empty slide plate of roll change buggy is regained and put in place, finishes the roll of cold pilger mill and changes.

Described push-pull device at fixed is a lift, and lift comprises motor and screw mandrel driving mechanism, and lift is installed on the base, and lift is rotated around datum axle by motor-driven; Screw mandrel drive mechanism screw mandrel stretches out and regains.

Useful result of the present invention is, owing to the present invention includes push-pull device at fixed and roll change buggy, roll change buggy flexibly connects and can slide at track by slide rail and track, but the slide plate that roll change buggy has two vertical tracks to move, two slide plates respectively are that independently moving body is vertical with track mobile under the effect of mobile drive deivce; Two one on slide plates are used to place the old roll that needs replacing, a new roll that needing to be used for placement; Push-pull device at fixed is used for releasing old roll that cold pilger mill changes a room slide plate to roll change buggy, is used for pulling out slide plate of roll change buggy and places new roll in cold pilger mill.Can realize the high speed roll change by push-pull device at fixed and roll change buggy, improve production efficiency, alleviate labour intensity.

The specific embodiment

As shown in Figure 1, 2, 3, the side direction roll change mechanism of double-roller cold pilger mill comprises push-pull device at fixed and roll change buggy 8, roll change buggy 8 flexibly connects by slide rail 1 and track 10, make roll change buggy 8 to the roll change position by slide rail 1 in track 10 slips, roll change buggy 8 can move around on the track perpendicular to rolling centerline.

But roll change buggy 8 has first slide plate 14 that two vertical tracks 10 move and second slide plate, 15, the first slide plates 14 and second slide plate 15 respectively to be moving body independently, under the effect of mobile drive deivce with track 10 vertical moving; First slide plate 14 and 15 1 on second slide plate are used to place 2, one on the old roll that needs to change and are used to place the new roll 3 that needs usefulness; First slide plate 14 and second slide plate, 15 any one the new roll 3 that may be used to place or old rolls 2.

Push-pull device at fixed is a lift 6, and lift 6 comprises motor 7 and screw mandrel driving mechanism, and lift 6 and motor 7 are installed on the base 5, and lift 6 is driven around 5 rotations of base by motor 7; The 4 extended and withdrawals of screw mandrel drive mechanism screw mandrel.Normal when rolling, lead screw of elevator is parallel to the side of main engine bed 13, roll change buggy 8 is parked near the end of main engine bed 13 away from roll, rotate the end alignment roll that lift makes screw mandrel during roll change, preprepared new roll 3 is contained on second slide plate 15 of roll change buggy 8, second slide plate 15 of adorning new roll is in " transporting position ", roll change buggy 8 is pushed near the main engine bed 13, first slide plate 14 that is used to adorn old roll 2 is stretched out the aligning framework window, make first slide plate 14 be in " roll change position ", motor 7 drives the screw mandrel 4 of lift 6, the screw mandrel 4 of lift 6 stretches out and promotes old roll 2, old roll 2 is moved along rolling centerline, lift 6 is shifted old roll 2 on roll change buggy first slide plate 14 onto, being placed on old roll 2 on roll change buggy 8 dollies and spurring first slide plate 14 makes it be in " transporting position ", use identical method that new roll 3 is loaded onto then, promote roll change buggy new roll 3 is aimed at framework window, second slide plate 15 of new roll is adorned in release, make it be in " roll change position ", with lift 6 new roll 3 is drawn in the frame again, roll change buggy 8 and push-pull device at fixed reset, promptly finish a roll change, the stroke of roll change buggy 8 is determined that by positioning baffle 11 and baffle plate 12 roll change buggy 8 is by chock block 9 location.When carrying out roll change, must there be a cover roll to be in " transporting position " of roll change buggy, tumbles to avoid dolly.
