Technical Field

The invention relates to the field of production and processing of metal sheets, in particular to a metal sheet bending system for a metal sheet.

Background

The sheet metal, a processing technology, has not yet a relatively complete definition. According to a definition in a professional journal abroad, the term can be defined as: the sheet metal is a comprehensive cold working process for sheet metal (generally below 6 mm), including shearing, punching/cutting/compounding, folding, riveting, splicing, forming (such as automobile bodies) and the like. The remarkable characteristic is that the thickness of the same part is consistent. In some sheet metal panel processing techniques, a sheet metal panel needs to be subjected to a bending process.

To the sheet metal panel that thickness is thinner, and need bend into 90 and need use manual bender, but manual bender is when carrying out the sheet metal bending, because thickness is less, consequently appear squinting easily when buckling and lead to the precision of buckling not high, and after buckling, need manual deduction to unload, cause workman intensity of labour to increase.
