Description

Technical Field

[0002] As an appearance part and an important part of the washing machine, the outer shell of the washing machine has very high requirements on the outer surface and cannot have any wear and damage. The level of its bending technology directly affects the appearance and performance of the washing machine.

[0003] During the bending process, the current bending machines can only bend parts with a specific diameter or a specific curvature, resulting in a relatively single bent product. When there is a certain bending deviation, it cannot be corrected. The correction work needs to be replaced with a new reverse bending machine with a repair function. Repeated clamping will cause a large dimensional deviation of the product, resulting in a greatly increased defective rate, affecting the quality of the product and reducing the bending efficiency.
