Abstract:
A tool feeding depth adjustment mechanism for a bending machine, comprising a rotating cover (10), a stopper (20), a screw (30), an adjusting nut (50) and a driving component; the rotating cover (10) is provided with a sealed end and an open end, and the stopper (20) is fixed on a rack of a bending machine; one end of the screw (30) is inserted into the rotating cover (10), and another end extends outside of the rotating cover (10) by means of the open end of the rotating cover, the screw (30) passing through the stopper (20) and being connected to a sliding block of the bending machine; the adjusting nut (50) is mounted within the rotating cover (10) and is threadedly screwed with the screw (30), and the rotating cover may drive the adjusting nut to rotate about the screw and cause the adjusting nut to move up and down along the screw; the driving component is connected to the sealed end of the rotating cover; an end of the adjusting nut (50) that is close to the stopper (20) is provided with a limiting projection (51), and an end of the stopper that is close to the adjusting nut (50) is provided with a limiting groove (21) that matches the size of the limiting projection (51).
