Description

Ring rotating experiment platform

Technical Field

The utility model belongs to the field of rotation simulation devices, and particularly relates to a ring rotation experiment platform.

Background

The aluminum alloy ring piece is manufactured by adopting a ring rolling process, wherein the ring rolling is an advanced plastic rotary forming process for forming the wall thickness, the height reduction, the diameter expansion and the section profile of the annular forging piece by using rolling equipment (ring rolling machine). The ring rolling process is used as an advanced continuous local plastic rotary forming process and has the forming characteristics of local loading, three-dimensional deformation and multi-pass rolling, and the ring rolling forming is a complex dynamic process of three-dimensional nonlinear multi-factor coupling action of materials, geometry and boundaries. At present, the main challenges facing the production of ring rolling parts in China are mainly reflected in the acquisition of geometric dimension parameters in the forming process except for the lag of the ring rolling process. In terms of size acquisition, currently, a method of measuring the diameter by using a manual caliper or a theodolite is still commonly adopted, the measuring method requires that a ring rolling part is in a static state, the aluminum alloy ring part is always in a high-temperature and rotating state in the ring rolling forming process, and the process requires one-time ring rolling forming, so that the current measuring method cannot realize online measurement of the forming size of the ring rolling part. In addition, the traditional lagging measuring method is complex in operation process, has huge potential safety hazards, and has the advantages of small measured data quantity, large error and out-of-tolerance size, so that machining allowance has to be increased, the cost is increased, and the workpiece is scrapped and the production efficiency is influenced.

In addition, because the aluminum alloy ring piece is always in a rotating state in the ring rolling forming process, the current detection method is mainly completed in a static environment, the real situation of the ring rolling process of the aluminum alloy ring piece cannot be reflected, and whether the rotating process affects the size detection cannot be determined. Therefore, the variable-speed multi-size aluminum alloy ring rotating experimental platform has important significance for simulating the ring rolling process of the aluminum alloy ring and reflecting the real ring rolling process of the aluminum alloy ring, so that the current theoretical research is ensured to be closer to the actual one.
