A Metal leveler is a piece of machinery employed for the purpose of straightening metal sheets. The following is a detailed introduction to the machine and its functionality.
Working principle
The Metal leveler functions on the basis of the elastic-plastic deformation characteristics of the material. The following are the primary working steps:
Material feeding: The sheet metal is fed into the levelling machine's feeding area, where after the roller conveyor system guides it to the working area.
Role of the upper and lower rollers: The machine generally comprises a set of upper rollers and a set of lower rollers, with an adjustable gap between the two sets. As the sheet metal passes through the gap, the roller conveyor system exerts pressure, causing the metal to undergo plastic deformation.
Plastic deformation: under the pressure of the upper and lower rolls, the metal plate undergoes elastic and plastic deformation, the internal stress and distortion are gradually eliminated, and the plate gradually becomes flat.Discharge: after a series of levelling processes, the treated sheet metal leaves the discharge opening, achieving the desired flatness and geometry.Fields of application.The Metal leveler is widely used in industrial production, mainly reflected in the following aspects:
Metal plate processing: widely used in the production and processing of cold rolled steel plate, hot rolled steel plate, stainless steel plate, etc., which can obtain higher flatness and surface quality to meet the needs of various industrial fields.Automotive industry: automotive manufacturing requires a large number of metal plates, levelling machine can make these plates to achieve precise flatness and geometric dimensions, to ensure the quality of automotive structure and appearance.
The home appliance manufacturing sector, for instance, utilises sheet metal in the production of refrigerators, washing machines and other products. In this context, levelling machines play a crucial role in ensuring the flatness of metal sheets, thereby contributing to the aesthetic appeal of the final product.In the construction industry, metal materials find extensive application in structural and aesthetic enhancement. The metal sheets processed with levelling machines adhere to construction standards, ensuring stability and enhancing the visual appeal of buildings.The shipbuilding industry is another notable application area. Shipbuilding requires a large number of steel plates, and levelling machines can effectively level the plates to ensure the quality of shipbuilding.The rolling stock industry involves the processing and splicing of various metal plates, and levelling machines can effectively correct the plates and improve the manufacturing precision.
The boiler and bridge industry, in particular, has been identified as a significant user of levelling machines, given the substantial number of metal plates involved in the manufacturing of boilers and bridges. The importance of strict adherence to levelling and correction in these contexts cannot be overstated when considering safety and stability requirements.The metal structure factory sector also stands to benefit significantly from levelling machines, as they play a crucial role in ensuring the quality and precision of various metal products.The global market for levelling machines has already surpassed USD 30 billion and is projected to reach an impressive USD 35 billion by 2025. The market is predominantly concentrated in Asia, Europe and North America, with China's market size being the largest globally, accounting for over 30%.In the ensuing years, with the sustained growth of global manufacturing, the levelling machine market is expected to exhibit stable growth.China market: Recent years have seen an average annual growth rate of 20% in China's levelling machine market, which reached RMB 10 billion in 2022 and is projected to exceed RMB 15 billion by 2025.The demand for high-end equipment is rising in China due to the transformation and upgrading of its manufacturing industry, and levelling machines, as a component of high-end equipment, are experiencing an expansion in market demand.
