Description

Turnover type flanging device and washing machine shell production line Technical Field The application relates to the technical field of washing machine shell production, in particular to a turnover type flanging device and a washing machine shell production line. Background The outer shell of the washing machine is taken as a main structural component of the washing machine, and the quality and the forming precision of the outer shell directly influence the quality and the market competitiveness of the final product. In modern washing machine design, the shell is designed with streamline large arc surface, the corner is also in large radius arc transition, and the design is beautiful and elegant, but brings challenges to manufacture. The conventional universal flanging machine is generally suitable for machining sheet metal parts with smaller bending radius or right angle, and has obvious technical limitations when machining workpieces with large arc sections and large flanging radius.
