Abstract

The invention provides a multi-roll transmission device, a cold straightening machine and a multi-roll transmission replacement method. The multi-roll transmission device is in transmission connection with the cold straightening machine; the cold straightening machine is provided with a power mechanism, and is selectively provided with one of multiple roll boxes, a pair of rolls is arranged in each roll box, and the multi-roll transmission device comprises a base, a pulley and a plurality of roll transmission mechanisms; the pulley is glidingly arranged on the base; the multiple roll transmission mechanisms are arranged on the pulley at intervals; the multi-roll transmission device is selectively in transmission connection between the roll in a machine frame and the power mechanism through one of multiple roll transmission mechanisms. The multi-roll transmission device has the advantage that by arranging the multi-roll transmission device between the machine frame and the power mechanism, and utilizing the multiple roll transmission mechanisms of the multi-roll transmission device, the transmission connection of the rolls in different sizes of roll boxes is realized, and the different sizes of workpieces can be straightened and processed.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a multi-roller transmission device, a cold straightening machine and a multi-roller transmission method thereof. Background technique [0002] Existing cold straightening machines mainly use a single-roller structure, and the scope of plate straightening applicable to this single-roller cold leveling machine is limited. In actual production, if it is necessary to straighten the plate beyond the straightening thickness range of the cold leveler, it is necessary to increase the number of levelers to meet the straightening of the plate with a larger thickness range, so the equipment investment cost is relatively higher. [0003] Therefore, proposing a cold straightening machine that can adapt to plates with different thickness ranges and has relatively low equipment investment cost has become a major technical problem to be solved urgently in this field.
