Description

Technical Field

[0001] The utility model relates to the field of rounding machines, in particular to a self-made flat steel bar rounding machine. Background Art

[0002] The rounding machine is a general-purpose equipment that bends metal sheets into cylindrical, arc-shaped or other shaped workpieces. It is based on the principle of three points forming a circle and uses the relative position change and rotational motion of the workpieces to cause continuous plastic deformation of the sheet to obtain a workpiece of a predetermined shape.

[0003] Flat steel bars refer to steel materials with a width of 12-300mm, a thickness of 4-60mm, a rectangular cross section and slightly blunt edges. Flat steel bars need to be rolled and shaped by a rolling machine during processing. At present, the rolling machines used in the market have a large center distance between adjacent sets of groove rollers, so the front end of the flat steel bars cannot be rolled during rolling, resulting in the front end still being straight, which requires subsequent manual cutting and welding, resulting in a waste of raw materials.
