Step 3: The locking plate continues to move downward, and the driving roller arranged on the locking plate cooperates with the transmission support plate to complete the longitudinal positioning of the steel section, and the driving roller is used to complete the transportation of the steel section; Step 4: The steering motor cooperates with the kinetic energy transmission member to realize the rotation of the supporting cylinder, thereby completing the control of the direction of the fixed steel section; Step 5. The return frame continues to move, and the energy supply part is inserted into the inner side of the energy supply pipe, driving the air inside the energy transmission box along the ventilation pipe into the inner side of the sealing sleeve, and the air inside the sealing sleeve enters the inner side of the energy conducting cavity along the pressure-stabilizing conduit, and the air inside the energy conducting cavity enters the inner side of the stabilizing support tube, and cooperates with the support part to realize the lifting of the transmission support plate. On the one hand, the lifting of the steel section is realized, and on the other hand, the T-shaped slider drives the connecting slide bar to be lifted synchronously, and the connecting slide bar can drive the pressure regulating part to move inside the connecting slide tube, and the air inside the connecting slide tube enters the inner side of the control cavity along the pressure-conducting tube, and the air inside the control cavity enters the inner side of the support tube, and cooperates with the support part and the mounting plate to realize the falling of the laser cutting head, and complete the control of the distance between the laser cutting head and the steel section; Step 6: The control motor can drive the threaded rod to rotate, and the threaded rod drives the movable seat to move along the wall of the support frame, and the movable seat drives the laser cutting head to move synchronously to complete the cutting of the steel; Step 7. The cut steel falls on the guide plate under the action of gravity. The guide plate drives the support block to move downward along the positioning rod. The guide plate cooperates with the push-pull rod to realize the movement of the buffer inside the energy absorption cavity to absorb the impact force. The guide plate transports the cut steel.
