Abstract

The invention discloses a high-rigidity rolling mill and belongs to the technical field of metal pressure processing. The high-rigidity rolling mill comprises a stander, a press-down system and a roller system, wherein an upper backup roller bearing pedestal is arranged between the press-down system and the roller system; a compaction inclined wedge block is arranged between the stander and the upper backup roller bearing pedestal; the compaction inclined wedge block is upward connected with a compaction hydraulic cylinder; the compaction hydraulic cylinder is fixedly connected with the stander; and the compaction inclined wedge block is downward spliced with the upper backup roller bearing pedestal to form a self-locking state. The high-rigidity rolling mill has the characteristics of high rigidity and high milling precision.

Description

technical field [0001] The invention relates to a high-rigidity rolling mill, in particular to a high-rigidity rolling mill suitable for high-precision plate and strip processing, and belongs to the technical field of metal pressure processing. Background technique [0002] With the continuous development of steel rolling technology, rolling mills of various roll systems and roll types have appeared one after another, and the reduction system, hydraulic servo system and computer control system have made great progress, which has greatly improved the manufacturing precision and control precision of rolled pieces. Big improvement. However, for the rolling mill itself, the stress deformation and vibration of its parts still have a great impact on improving the stiffness and rolling precision of the rolling mill, such as figure 1 As shown, the deformation of the three main components of the frame system 1, the pressing system 2 and the roll system 3 is the main reason for affec...
