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.
