Description

Technical Field

[0001] The invention relates to the technical field of metal rolling, in particular to a rolling forming device for elevator metal accessories. Background Art

[0002] Metals are substances that exhibit lustre (strong reflection of visible light), ductility, and good electrical and thermal conductivity. These properties are all related to the presence of free electrons within metal crystals. In nature, the vast majority of metals exist in a combined state, with a few, such as gold, platinum, silver, and bismuth, existing in a free state. Most metal minerals are oxides and sulfides, with chlorides, sulfates, carbonates, and silicates also existing. Metals are connected by metallic bonds, allowing them to be re-established by simply changing positions. This explains their excellent ductility. Metallic elements typically only exhibit positive valence in compounds, and those with larger relative atomic mass are referred to as heavy metals. Currently, when impurities are present on the metal surface during the rolling process, the impurities trapped between the workpiece and the rolling rollers can affect the workpiece's rolling quality and surface finish. Hard impurities on the workpiece can even damage the rolling rollers. Summary of the Invention
