Embodiment

[0029] The method of the present invention includes the following steps:

[0030] Step 1. The cutting of special-thickness plates requires automatic cutting by a manipulator. Therefore, this system needs to be selected under an automatic cutting system, such as a gantry three-dimensional cutting system.

[0031] Step 2. According to the system composition Figure 4 Install three flame guns on the head of the flame cutting machine, and adjust the three flame guns to be installed on a line.

[0032] Step 3. First move the cutting machine out of the cutting workpiece, ignite the flame gun I and adjust the flame energy rate and properties. Then ignite the flame gun II and adjust the flame energy rate and properties. Finally, the secondary flame of the flame gun III is ignited and adjusted to a neutral flame, and then the main flame is ignited and flame adjustment is performed to make it burn stably, and the flame length reaches the longest.

[0033] Step 4. Move the head of the cutting m...

Abstract

The invention relates to a flame cutting method of a thick steel plate. The flame cutting method comprises the following steps: three flame guns are mounted on a machine head of a flame cutting machine for igniting secondary flame of a flame gun I, a flame gun II and a flame gun III in sequence; then, main flame of the flame gun III is ignited, and the flame is adjusted; the machine head of the cutting machine is shifted, so that the flame gun I is positioned on a cutting path; the flame gun II is positioned in a cutting preparation starting position; main flame of the flame gun III can heat the lower half part of a metal plate to be cut; when an ignition temperature is reached, a cutting oxygen valve is opened; and when the flame guns reach the terminal of the metal plate to be cut, the flame guns are closed. The flame cutting method proposes a combined flame cutting principle, that is, the system combination of the three flame guns and corresponding functions are used for realizing the cutting of the large-thickness metal plate. The flame cutting method realizes smooth cutting of workpieces with ultralarge thickness, and improves the economy.

Description

Technical field [0001] The invention belongs to the field of metal cutting and blanking processing, and in particular relates to a flame cutting process method for extra-thick steel plates, which is suitable for heavy equipment manufacturing enterprises. Background technique [0002] According to the processing principle, the thermal cutting of metal is divided into flame cutting, plasma arc cutting and laser cutting. Flame cutting belongs to the oxidative cutting of metals. It uses flame to preheat the metal to reach the ignition point of the metal and then gives pure oxygen to oxidize it into low-melting oxidized slag, and at the same time release a large amount of heat to further heat the metal to be cut. At present, the maximum thickness of conventional flame cutting can reach 1800mm. Plasma arc cutting is a process of using high temperature plasma arc to heat and melt metal and blow it open to form a kerf. It belongs to melting cutting. However, due to the limitation of po...
