The invention discloses a full-automatic groove breaking
necking machine. The full-automatic groove breaking
necking machine structurally comprises a groove breaking
necking pressing cylinder, a beamshrinking groove, a carrying lifting table, an
electromagnetic valve seat, a
relay, an
electric control box and a transmission case. According to the full-automatic groove breaking necking
machine, the groove breaking necking pressing cylinder is matched with the beam shrinking groove, so that a rotary threaded groove cleaning effect is formed, and steel fragments splashed during
stamping neckingform a surrounding collection guide effect; a frame connecting rod forms a gradient type combined winding
brush effect, so that impurities penetrating through the surface can be conveniently cleaned in the equipment
stamping process, and the size precision of a
pipe opening assembled in the later period can be conveniently adjusted; then a
pipe opening fine adjustment frame is used for forming anannular frame longitudinal alignment correction effect on the
stamping pipe opening, so that the longitudinal line distance and a rotary sliding
brush form a combined linkage multi-axis motion effectthrough a
bevel gear supporting frame, the
stress point of a knife rest during groove breaking is improved, and a rotary unloading
machining effect is formed; and the groove breaking sliding
inertia is assisted to be pushed, so that the quality of a
scaffold steel pipe machined by the whole groove breaking locking opening is improved.
