Abstract

The utility model belongs to the field of metallurgical equipment, and particularly relates to a side roll changing mechanism for a two-roll cold tube rolling mill. The side roll changing mechanism for the two-roll cold tube rolling mill is characterized by at least comprising a push-pull device and a roll changing trolley, wherein the roll changing trolley is movably connected with a track through a slide rail and slides in the track, the roll changing trolley is provided with two vertical track moving slide plates, and the two slide plates are independent moving bodies and vertically move in the track under the action of a movement driving device; one of the two slide plates is used for placing an old roll, and the other one is used for placing a new roll; and the push-pull device is used for pushing the old roll replaced in the cold tube rolling mill to an empty slide plate of the roll changing trolley and pulling out the new roll placed in one of the slide plates of the roll changing trolley to the cold tube rolling mill. The side roll changing mechanism for the two-roll cold tube rolling mill has simple structure, is convenient and quick to change the roll, and can improve the production efficiency.

Description

A kind of side direction roll change mechanism that is used for double-roller cold pilger mill

Technical field

The utility model belongs to field of metallurgical equipment, as a kind of process equipment of metal tube rod, and particularly a kind of side direction roll change mechanism that is used for 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.

The utility model content

The purpose of this utility model provides a kind of side direction roll change mechanism that is used for double-roller cold pilger mill that a kind of simple in structure, roll change is convenient fast, can enhance productivity.

The technical solution of the utility model is: design a kind of side direction roll change mechanism that is used for double-roller cold pilger mill, it is characterized in that: which comprises at least push-pull device at fixed and roll change buggy, 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.

Described push-pull device at fixed is a lift, and lift comprises motor and the brave driving mechanism of silk, and lift is installed on the base, and lift is rotated around datum axle by motor-driven; The brave drive mechanism silk of silk is brave to be stretched out and regains.

Useful result of the present utility model is, because the utility model comprises 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.

Description of drawings

Below in conjunction with Figure of description and embodiment the utility model is described further.

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the vertical view of lift side direction roll change mechanism;

Fig. 3 is the roll change buggy schematic diagram of lift side direction roll change mechanism.

Among the figure: 1, slide rail; 2, old roll; 3, new roll; 4, silk is brave; 5, base; 6, lift; 7, motor; 8, roll change buggy; 9, chock block; 10, track; 11, positioning baffle; 12, baffle plate; 13, main engine bed; 14, first slide plate; 15, second slide plate.

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 the brave driving mechanism of silk, 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; Brave drive mechanism the silk brave 4 extended and withdrawals of silk.Normal when rolling, the brave side that is parallel to main engine bed 13 of lift silk, roll change buggy 8 is parked near the end of main engine bed 13 away from roll, rotate lift during roll change and make the brave end alignment roll of silk, 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 silk brave 4 of lift 6, the silk brave 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.
