The invention relates to an efficient waste collecting and drawing assembly of a punching machine. The efficient waste collecting and drawing assembly comprises a frame body (1), wherein the frame body (1) is structurally designed into two parts, a waste collecting tank device (2) is arranged below a punching grinding tool, a bending positioning frame (3) is arranged on sides, and a drawing component is located on the outlet end of a workpiece and comprises a rotary guide rail (4), a positioning nut (5) and a width limiting device (6); during operation, the frame body (1) is in a suspension state, after the workpiece is punched, discharged waste is intensively collected, and additionally, the equally spaced drawing operation is performed; a prompt device (7) is arranged, and an informationprompt mode is sound or LED (Light Emitting Diode) light display; and the tail end of the waste collecting tank device (2) is inclined at 30 degrees, and waste can be replaced only by pressing the bottom of the tank downwards by an operator. The efficient waste collecting and drawing assembly has the advantages of simple structural design, simplicity and convenience in adjustment and high practicability, the waste can be intensively collected, additionally, the force of supervision of the operator is reduced, and the automatic drawing operation is effectively realized.
