Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, in particular to an auxiliary cutting device for large-sized thick steel plates. Background Technique

[0002] A steel plate is a flat steel product cast from molten steel and pressed after cooling. Steel plates are classified by thickness into: thin steel plates (with a thickness of 0.2 - 4 mm), medium-thick steel plates (with a thickness of 4 - 60 mm), and extra-thick steel plates (with a thickness of 60 - 115 mm); if classified by rolling method, they are divided into hot-rolled and cold-rolled; by professional use, there are plates for oil drums, enamel plates, bulletproof plates, etc. When in use, the steel plate needs to be cut into the required size. A large steel plate cutting device proposed in the prior art publication number CN203791802U includes a nozzle support, a number of nozzles, and support rails laid on both sides of the nozzle support. The nozzle support includes two support rods standing on both sides respectively. Between the two support rods, a pipeline fixing rod and a nozzle fixing rod are successively arranged from top to bottom. A number of nozzles are arranged on the nozzle fixing rod. The support rods stand on the support rails and can slide along the support rails. However, it is not convenient to assist in positioning the steel plate and not convenient to finely adjust the steel plate, thus resulting in the problem of low cutting efficiency. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an auxiliary cutting device for large-sized thick steel plates that can convey thick steel plates, clamp and guide the steel plates, ensure cutting accuracy, improve flexibility, and improve cutting efficiency.

The bottom of the moving arm is installed at the front end of the base through the moving component. The flame cutting machine is installed on the moving arm through the position adjusting component; the thick steel plate is conveyed above the base through the conveying and supporting component and supported. The steel plate is clamped and guided through the positioning component to ensure cutting accuracy. The moving component drives the moving arm to move left and right at the front end of the base to adjust the position of the flame cutting machine. At the same time, the position adjusting component can drive the flame cutting machine to move back and forth to complete the cutting of the steel plate, improve flexibility, increase the working range, and is beneficial to improving cutting efficiency.

[0005] Preferably, the conveying and supporting assembly includes multiple groups of supports, multiple conveying shafts, multiple heat-resistant conveying rollers, a transmission, a conveying motor, and multiple sprockets.
