Description

Technical Field

[0001] The present invention relates to the technical field of automatic cutting, and in particular to an automatic cutting device which is easy to position. Background Art

[0002] Plasma arc cutting is to pass a mixed gas through a high-frequency arc. The gas can be air or a mixture of hydrogen, argon and nitrogen. The high-frequency arc "decomposes" or ionizes some gases into basic atomic particles, thereby generating "plasma". Then, the arc jumps to the stainless steel workpiece, and the high-pressure gas blows the plasma out of the cutting torch burner at an outlet speed of 800 to 1000 meters per second (about 3 Mach). In this way, the high energy released when the various gases in the plasma return to normal state produces a high temperature of 2700°C. This temperature is almost twice the melting point of stainless steel. As a result, the stainless steel melts quickly, and the molten metal is blown away by the ejected high-pressure airflow.

[0003] Chinese patent CN2022107520853 discloses a plasma automatic cutting device, wherein the input end of the control box is connected to an air compressor and a plasma power supply respectively; the output end of the control box is connected to a cutting gun adjustment device, and an upper pipe lifting device is provided on the cutting gun adjustment device, and one side of the upper pipe lifting device is connected to a pipe clamping plate, and the pipe clamping plate is provided with a pipe to be cut. The device can complete the automatic processing of the groove of the pipe diameter, ensure the processing uniformity and consistency of the groove, high production efficiency, and no safety hazards; a 1-ton crane can rotate 360° freely, and the weight of the lifting pipe ring is about 2000Kg, which solves the problem of hoisting large-diameter pipes; the cutting gun adjustment device enables the cutting gun to be adjusted longitudinally along the pipe diameter to adapt to the range of pipe diameter changes.
