1. A bending apparatus for machining a device to be bent, wherein the device to be bent includes a body portion and a portion to be bent connected to each other, and the portion to be bent includes a first portion and a second portion that are away from the body portion in sequence;
the bending apparatus comprising:
a fixing structure configured to fix the body portion of the device to be bent;
a first driving mechanism and a first pressing head connected to the first driving mechanism; wherein the first driving mechanism is configured to drive the first pressing head to move onto a first surface of the first portion, and to drive the first pressing head to push the first portion to rotate to a first side of the body portion, so that the first portion is parallel or substantially parallel to the body portion; and
a second driving mechanism and a second pressing head connected to the second driving mechanism; wherein the second drive mechanism is configured to drive the second pressing head to move onto a second surface of the second portion; wherein the second surface and the first surface are respectively located on two sides of the portion to be bent; wherein
the second driving mechanism is further configured to drive the second pressing head to pull the second portion to rotate to the first side of the body portion while the first pressing head pushes the first portion.
