Description
Technical Field
The invention relates to a steel bar cutting device. In particular to a fixed-size material cutting device for cutting a steel bar according to a set length in the process of continuously straightening the steel bar by a straightening machine.
Background
As is known in the steel processing industry, steel coils are formed by rolling steel coils into coils. The rolled steel rod with the wire rod is processed into the steel rod with the required length, and the steel rod with the required length needs to be cut by a fixed-length material cutting device while being continuously straightened.
At present, the fixed-length material cutting device used for cutting the steel bar according to the set length in the process of continuously straightening the steel bar by a straightening machine is a traditional fixed-length material cutting device. The traditional sizing and material cutting device comprises a bedplate and a controller, wherein the bedplate is a cuboid, and a straightening machine is arranged at one end of the bedplate. The platen at the discharge end of the straightener is provided with a material cutting table, and the material cutting table are in sliding fit. The material breaking table is rectangular, one end of the material breaking table, which is adjacent to the straightening machine, is connected with a cutter holder, and a material breaking oil cylinder is fixed on the cutter holder. The outer end of a piston rod of the material breaking oil cylinder faces downwards and is connected with a cutter head. One end of the material breaking table, which is far away from the straightening machine, is connected with a sizing block. The tool apron is provided with a sliding hole and a flat hole, and the sliding hole is parallel to the flat hole in the longitudinal direction. A guide rod is arranged in the slide hole, a portal frame is arranged on the bedplate at one side of the cutter holder, and two ends of the guide rod are respectively connected to two vertical arms of the portal frame. An upright post is arranged on the bedplate at one side of the material breaking table, and a reset oil cylinder is arranged between the upright post and the cutter holder. The flat hole corresponds to the discharge hole of the straightening machine and the upper side surface of the material breaking platform. And a probe is arranged at one end of the top beam of the portal frame, which is adjacent to the straightening machine, and the probe and the material breaking oil cylinder are connected with a controller by virtue of a lead. Under the non-working state, the tool apron, the material cutting oil cylinder, the tool bit, the material cutting platform and the sizing block, the eccentric wheel and the like on the material cutting platform which are connected into a whole are moved backwards under the action of the reset oil cylinder, so that the tool apron is moved to the front of the vertical arm of the portal frame adjacent to the straightening machine. When the steel bar straightening machine works, a steel bar coming out of the front end of the straightening machine penetrates through a flat hole in the tool apron and then continues to move forwards until the steel bar is abutted against the sizing block, so that the tool apron, the material breaking oil cylinder, the tool bit, the material breaking table and the sizing block, the eccentric wheel and the like on the material breaking table which are connected with the tool apron into a whole move forwards under the action of the reset oil cylinder, and the tool apron is separated from the vertical arm of the portal adjacent to the straightening machine. At the moment, the probe receives a signal from the forward movement of the tool apron, sends the signal to the controller, and a computer in the controller gives an instruction to the material breaking oil cylinder, and a piston rod of the material breaking oil cylinder extends downwards and drives the tool bit to act so as to cut the fixed-length steel bars. Then, when the knife holder and the material cutting oil cylinder, the knife head, the material cutting platform and the sizing block, the eccentric wheel and the like on the material cutting platform which are connected with the knife holder are restored to the original positions under the action of the reset oil cylinder, the cut-off fixed-length steel bar is taken down from the material cutting platform by manual operation of workers. And then repeating the actions to cut the straightened steel strip into a fixed-length steel strip. Because need the workman to adopt manual operation to take off the length steel bar that is cut off from disconnected material bench, and the upper surface of disconnected material bench is the plane, and the width of billet is narrower than the width of disconnected material bench upper surface again for very inconvenient when taking off the length steel bar with the hand, it is more troublesome to operate.
