SU37669A1 - Adaptation to the trio mill for feeding material into the lower streams - Google Patents

Description

An adaptation to the trio mill is proposed to transfer rolled material from the streams of the upper pair of rolls to the lower streams. The strip leaving the upper streams enters along a guide on a level pair of rolls, then is caught by the rollers and fed to the lower stream.

In the schematic drawing of FIG. 1 shows the device in longitudinal section; Fig, 2 is the same in cross section; FIG. 3 is a view from above, and FIG. 4-piece fixture.

The proposed adaptation to the trio mill for feeding material into the lower streams is a rigid frame 1, which can move along the line of the mill along the guide rails 2. The frame consists of a fixed part 6 and a movable part 4, which with screws 5 with handwheels 6 it can be installed at a known distance from the fixed part 3, depending on the thickness of the rolled strips. At the top of part 3, a guide angle 7 is mounted, provided along the length with slots with fixing countersunk bolts, which allow some movement of the angle piece in part 3 to the right or left to install it exactly against the upper roll stream. In the lower part of the frame 3 there are three or more (depending on the length of the rolled strips) drive feed rollers 8, carrying on their axles helical wheels 9, which engage from the Worm 10 and 11. The latter lies in the spindle 12 and is set in motion using the transmission 13 from the motor 14 mounted on the frame of the device. In the movable part 4 there are idle rollers 15 placed in the frame 16, movable along the guides 17 of the part 4. Along the frame 16 on the part 4 is located in the support of 19 wa; 18 with cams 20, rotated “through the front of 21 from the motor 22. The flat springs 23 constantly press the frame 16 with the rollers 15 to the cams JO.

The strip of rolled metal, the exit from the upper pair of rolls, ends up on the square 7 and slides along it until it comes out of the rolls. The roll out of the rolls, the strip rolls down from part 3 into a shed 24 and rests on the supports 25 attached to the frame 16. Since the motors 22 and 14 are working at this time,

the shaft 18 with its fists 20 moves the frame 16. with the rollers 15 along the guides 7 together with the rolled strip lying on the supports 25 to the rollers 8, rotated from the motor 14. As a result of the training, the rollers 8 feed the strip with the rear end back into the lower pair of rollers. In this way, automatic feeding of rolled strips from one trio mill to another is carried out.

Pedal 28 is used so that when the strips are fed into the rolls, the frame 16 with rollers 15 constantly presses the strip to the rollers 8, beyond the cost of movement of the kulaks 20 of the shaft 18. The strip, lying on the supports 25, simultaneously lays down on the pedal 26 and, pressing the latter downwards, thereby activates the double-arm lever 27, equipped with a locking pin 28. When the cams 20 press the strip to the rollers 8, the cone of the pin 28 enters the recess 29 on the frame 16, holding the last

in this position until the band comes off pedal 26. As soon as the pedal is exhausted, the sleep rises, the frame 1o ossiol falls. and the action of the spring action 2J to move one another to the fists 20.

The subject matter of the invention.
