Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a flattening device with good safety. Background Art

[0002] Sheet metal is a component made of thin metal sheets through cutting, bending, stamping, welding and other processing processes. Sheet metal flattening equipment is used to flatten sheet metal. During the sheet metal processing, the surface of the sheet metal may be uneven due to the bending, stamping and other processing operations of the material. In order to make the surface of the sheet metal flat, it needs to be processed by flattening equipment.

When flattening the sheet metal, the user needs to manually reach into the equipment to place and fix the sheet metal, and its operation method has certain safety hazards. At the same time, placing the sheet metal directly on the processing platform without fixing the sheet metal may reduce the effect of the sheet metal flattening processing. Therefore, the utility model provides a flattening equipment with good safety to solve the problems raised in the above background technology. Utility Model Content
