Novel roller ring replacing device for novel three-roller precision rolling mill

Abstract

The invention belongs to the technical field of rolling mill auxiliary tools, and particularly relates to a novel roller ring replacing device for a three-roller precision rolling mill. According to the technical scheme, the novel roll ring replacement device comprises a lifting plate, wherein one end of the lifting plate is hinged with a first connecting plate, the other end of the limiting plateis hinged with a second connecting plate, the other end of the first connecting plate is fixedly provided with a first clamping plate, the other end of the second connecting plate is fixedly providedwith a second clamping plate, positioning pins are fixed to the first clamping plate and the second clamping plate, and the middle section of the first connecting plate is hinged with the middle section of the second connecting plate. The novel three-roller precision rolling mill roller ring replacing device is convenient and reliable to operate.

Description

technical field [0001] The invention belongs to the technical field of rolling mill auxiliary tools, and in particular relates to a novel three-roll precision rolling mill roll ring replacement device. Background technique [0002] The three rolls of the three-roller section steel mill have the same diameter and are all driven. After the rolled piece is rolled between the lower and middle rolls, it is rolled back from the upper and middle rolls, and rolled back and forth on one stand for many times. Various horizontal section steel mills and wire rod mills mostly belong to this category. [0003] The stick rings of the three-roll mill are installed on the long shaft. The structural space for changing the roll ring is very limited, and it is not easy to operate. Conventional full-manual roll change requires at least two workers to operate, one lifts the roll ring and aligns the long axis hole, and the other operates the manipulator to install the long axis to fix the roll ri...

AI Technical Summary

Problems solved by technology

The structural space for changing the roll ring is very limited, and it is not easy to operate. Conventional full-manual roll change requires at least two workers to operate, one lifts the roll ring and aligns the long axis hole, and the other operates the manipulator to install the long axis to fix the roll ring

[0004] Manual replacement of roll rings is not only difficult to operate, but also prone to damage to roll rings, long shafts of precision rolling mills, etc. due to misoperation
