The invention belongs to the technical field of manufacturing of aluminum
alloy doors and windows and particularly relates to a
cutting machine for window frames of the aluminum
alloy doors and windows. The
cutting machine comprises a
workbench, a supporting frame, an air cylinder and a motor, wherein the supporting frame is fixed on the
workbench, the air cylinder is fixed above the supporting frame, guiding rails are arranged between the supporting frame and the
workbench, a sliding block is mounted on one side of the motor and slidingly matched with the guiding rails, a
piston rod of the air cylinder is fixedly connected with the upper side of the motor, a
cutting wheel is arranged on and in keyed connection with an output shaft of the motor, and limiting blocks are arranged in positions, corresponding to the cutting wheel, of the workbench. With the adoption of the cutting
machine, the to-be-
cut window frames can be arranged between the left limiting block and the right limiting block which are adjusted in advance, the air cylinder is started and drives the motor to move downwards along the guiding rails, cutting of the window frames is completed,
cut positions are accurate, persons are far away from the cutting wheel in the process, the personal safety is guaranteed, the working efficiency is greatly improved, and the production cost of an enterprise is saved.
