Sheet metal bending brake |
摘要 |
A bending brake assembly for manually bending pieces of sheet metal material including a base supporting a plurality of c-shaped members presenting opposing clamping surfaces for receiving the sheet metal material. An extension extends away from the clamping surfaces with a socket connection rotatably supporting a bending member on the base for bending the sheet metal material disposed between the clamping surfaces. The socket connection includes a mate portion and a female portion in sliding engagement with one another as the bending member moves between a pre-bending position, a first operating position, and a second operating position. A finger extends from the male portion and defines a gap between the finger and the extension when in the pre-bending position with the finger maintaining the gap as the finger moves from the pre-bending position to the first operating position and the finger engaging the extension when in the second operating position.
