Abstract

The invention provides a material cutting device used for a bar straightening cutting machine, belonging to the mechanical technical field. The material cutting device solves the problems that the surface of the existing material cutting device is easy to be damaged and the end surface thereof generates an inclination. The material cutting device of the bar straightening cutting machine is arranged at a discharge port of a rebar straightening device; a frame is provided with a guideway which is horizontally arranged; the guideway is provided with a slipway which is provided with a material cutting die consisting of a fixed die and a movable die; the fixed die is fixed on the slipway; the slipway is fixed with a drive mechanism which is connected with the movable die and can drive the movable die to move up and down; the slipway is fixed with a sizing mechanism which pushes against the head of the bar and drives the slipway to move along the advancing direction of the bar; the materialcutting die is arranged between the discharge port and the sizing mechanism; a recovery spring which is used for recovering the slipway is arranged between the slipway and the frame. The material cutting device has the advantages that the end surface of the cut bar is smooth and generates no flat shape, and the noise is little, etc.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a cutting machine, in particular to a cutting device of a steel bar straightening and cutting machine. Background technique [0002] Coil-shaped steel wires generally need to be straightened and cut before they can be used. After straightening and cutting the steel wire, no slippage is allowed on the surface, the strength of the steel bar is not allowed to change, and the mechanical properties must remain basically stable. [0003] At present, the cutting part in the steel bar straightening and cutting machine usually uses a motor, a pulley, a gear and an eccentric shaft to drive a moving knife to reach the cutting steel wire. Due to the relative movement between the steel wire and the cutting knife and the shape of the knife, after the steel wire is cut off, the surface is easily damaged. The cutting head has a 3-4mm long flat shape, and the end surface has a slope, which affec...
