Description

Technical Field

[0001] The utility model relates to the technical field of metal plate strip shaping, in particular to a metal plate strip shaping device. Background Art

[0002] The metal strip shaping mainly adopts the roller pressing shaping method. In the actual shaping process, the metal strip is squeezed and corrected by the upper and lower pressing rollers. In order to ensure the stability of the strip conveying process to the pressing roller, a guide roller is set at the front end of the pressing roller to assist the conveying of the metal strip and increase the tension of the metal strip. However, in actual use, due to some bending problems of the metal strip itself, the output speed is unstable during the release process from the metal winding, which can easily cause insufficient tension of the metal strip entering the pressing roller, affecting the shaping effect. In addition, when switching between metal strips of different thicknesses, it is difficult to adjust the distance between the two pressing rollers, affecting the processing efficiency.

[0003] Therefore, in view of the deficiencies in the prior art, the present invention discloses a metal strip shaping device to solve the above problems.
