Problems solved by technology

The traditional drive roller replacement operation is generally manual, using a simple support frame to support and fix the matching parts that the drive roller is connected to, and then remove the original roller and replace it with a new roller. This traditional drive roller replacement operation is very efficient. Low
[0003] In addition, the inner hole of the traditional simple support frame used is flat, and the end of the driving roller is also flat. Due to the change of the position of the fittings that the driving roller is mated with during the docking, the difficulty of docking is increased, and High labor intensity and low efficiency of roll changing

Abstract

The roller changer for multiple roller rolling mill includes frame, two-layer connecting shaft seats, rotary connecting shafts supported with the connecting shaft seat, and sleeves in one end of the connecting shafts. Under the support of the frame, the connecting shaft seats and thus the connecting shafts may be shifted vertically and / or horizontally, while the sleeves are relatively fixed. The present invention is favorable to the centering of driving rollers and the automatic centering of the sleeves to realize fast roller change in high efficiency.

Description

technical field [0001] The invention relates to a rolling mill auxiliary device, in particular to a roll changing device for a multi-roll rolling mill. Background technique [0002] Rolling mills are commonly used mechanical equipment in the industrial field, and the drive rollers of the rolling mill need to be replaced after a period of use. The traditional drive roller replacement operation is generally to use a simple support frame to support and fix the matching parts that the drive roller is connected to, and then remove the original roller and replace it with a new roller. This traditional drive roller replacement operation is very efficient. Low. [0003] In addition, the inner hole of the traditional simple support frame used is flat, and the end of the drive roller is also flat. Due to the change of the position of the fittings that the drive roller is mated with during the docking, the difficulty of docking is increased, and The labor intensity is high, and the e...
