Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe production, in particular to a steel plate raw material cutting device for steel pipe production. Background Art

[0002] Steel pipe is a hollow long steel strip with a hollow cross-section. Its length is much larger than its diameter or circumference. It is usually made by cold drawing, cold rolling, hot rolling and other methods. Steel pipes are divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape; they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes according to the material; they are divided into steel pipes for pipelines, engineering structures, heat exchange equipment, machinery manufacturing for petrochemical industry, high-pressure equipment for geological drilling, etc. according to the use. Steel pipes need to cut the steel plate raw materials used for steel pipes during the production process; according to the authorization announcement number: CN 219648828U, a patent document named "A steel plate cutting device", is provided with a clamp driver and a clamp plate. The clamp driver is a pneumatic telescopic controller, which responds quickly after receiving a command. When the steel plate is placed on the cutting table, the clamp driver is controlled to retract, and the clamp plate presses the steel plate to effectively fix the steel plate. The slider base is a pneumatic slider. After the steel plate is fixed, the slider base is controlled to slide on the slide bar, and the saw blade cuts the steel plate.
