Split frame multi-roll mill

Abstract

The invention discloses a multi-rack type multi-roller rolling mill, which comprises an upper rack, a lower rack, an upper half roller system and a lower half roller system, wherein the upper half roller system and the lower half roller system are respectively arranged in the upper rack and the lower rack; the upper rack and the lower rack are connected by bolts; four corresponding corners between the upper rack and the lower rack are respectively provided with a vertical guide pillar used for performing a reinforcement function; the top end of the upper rack is provided with six regulation oil cylinders used for regulating a plate shape and a pressing mechanism, wherein the pressing mechanism is used for causing two supporting rollers in the middle in the upper half roller system to move and regulate roller gaps and rolling force; the bottom of the lower half roller system is provided with a movable edge roller seat; a roller diameter compensation device is arranged below the edge roller seat; the roller diameter compensation device comprises a tapering wedge oil cylinder, an upper wedge block and a lower wedge block; the shape of the upper wedge block and the shape of the lower wedge block are matched; the big head end of the lower edge block is connected with the tapering wedge oil cylinder used for pushing the lower wedge block to horizontally move.

Description

technical field [0001] The invention relates to a split-frame multi-roll rolling mill, which belongs to the field of cold rolling equipment. Background technique [0002] At present, general-purpose cold plates are very common in the market, and the benefits have become very meager. However, the demand for thin and refined plates and strips is constantly increasing, and the benefits are relatively optimistic. The original four- and six-high reversing mills were difficult to roll thin-gauge products due to the large diameter of the work rolls, and because the work rolls, back-up rolls and archways were heavy and bulky, the production and operation costs were high, and it was difficult to adapt to the increasingly fierce advantage in market competition. Due to the small diameter of the work rolls, the multi-roll mill is obviously superior to the four- and six-roll mills in terms of extremely thin strips and difficult-to-deform metals, and has a significant energy-saving effec...

Problems solved by technology

However, the 20-high rolling mills on the market adopt archway-type upper and lower frames, which have the following defects: heavy weight, large volume, slightly poor rigidity, small opening, and large errors in static accuracy and dynamic accuracy during installation and adjustment.
