Description

Automatic roundness correction machine

Technical Field

The utility model relates to plate roller processing equipment, in particular to an automatic roundness correcting machine.

Background

The existing automatic three-roller roundness correction machine principles are divided into two types: the upper roller pressing distance is controlled by the inductive switch, the position of the inductive switch is fixed, no matter how large the diameter is, the pressing distance of the wall of the multi-thickness tube is fixed, and therefore, a part of the calibrated plate roller does not reach the standard, and turning is often not started; the other is to control the pressing distance of the upper roller by detecting the current of the roundness correction machine through a current transducer and an AD conversion module. The disadvantage is that the plate roller has different lengths (different currents) and the pressing distance is different under the condition that the diameter is the same as the pipe wall thickness, the long plate pressing distance is less, and the calibrated plate roller precision is often not up to standard.
