Device for measuring precision cold rolling thickness of single plate

Abstract

The invention belongs to the technical field of mechanical equipment and relates to a device for measuring the precision cold rolling thickness of a single plate. In the invention, a special roller way system is designed specific to a plate-coil dual-purpose rolling mill, i.e., an inner machine front roller way and an inner machine back roller way which are adjacent to the rolling mill are partitioned into two-section roller ways, and a gap is formed between every two sections of roller ways. The inner machine front roller way is partitioned into an operation side inner machine front roller way and a transmission side inner machine roller way, and the inner machine back roller way is partitioned into an operation side inner machine back roller way and a transmission side inner machine back roller way, so that rays of thickness measuring instruments in front of and behind the rolling mill pass through the center of the single plate in the rolling process, and accurate thickness measurement is realized. In the cold rolling process of a single plate, the head part of the single plate is inserted into a roller way when downward buckling occurs. In the invention, each section of roller way is designed with a patterned roller structure, so that the single plate is prevented from being inserted into roller way gaps.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a thickness measuring device for precision cold rolling of a single sheet. Background technique [0002] In the current cold rolling production, tension coil rolling is mostly realized, but for the rolling of special varieties such as titanium alloys, it is difficult to form coils due to the small demand for a single batch, or due to the large deformation resistance and difficulty in bending Rolling, mostly using tension-free single-sheet rolling. [0003] Sheet sheet cold rolling can be completed on a dedicated sheet sheet rolling mill, or on a sheet-coil dual-purpose rolling mill. There is no difference between the rolling mills of the two, both are four-high or six-high reversing rolling mills, mainly due to the difference in the configuration of the roller tables before and after the machine and the configuration of the coiler. The special-purpose plate rolli...

Problems solved by technology

[0004] The current special-purpose sheet-fed rolling mills generally have low automatic control accuracy, and thickness gauges are rarely installed, while special-purpose strip rolling mills are mostly installed with X-ray or gamma X-ray thickness gauge, and equipped with high-precision thickness automatic control system, that is, AGC
