The rotating shaft is positioned on the left side and the upper side of the workbench, the cutter is installed on the rotating shaft, and the cutter face of the cutter is positioned between the electromagnet and the supporting block.
As a further improvement of the invention, the feeding mechanism comprises side plates which are symmetrically arranged on the workbench, a small shaft is arranged between the side plates, and a roller sleeve is sleeved on the small shaft.
As a further improvement of the invention, the right side of the workbench is also provided with a reducing cylinder.
as a further improvement of the invention, the right side of the steel bar is fixedly connected with the reducing cylinder through a connector.
as a further improvement of the invention, the size of the inclination angle is 5-10 degrees.
As a further improvement of the invention, the rotating shaft is externally connected with a lifting mechanism.
the invention has the beneficial effects that:
Tightly hold the billet all the time by the electro-magnet at the in-process that the billet is cut off and withdraw from until the cutter, the relative position of cutter and billet remains stable all the time, has effectively prevented that the billet from cutting off the change of the local material of taking place in the twinkling of an eye and causing the fracture of cutter and scrapping, has effectively prolonged the life of cutter.
