Flame thermal cutting groove head mechanism device

Abstract

The invention relates to a flame thermal cutting groove head mechanism device, and belongs to the technical field of flame cutting devices. A transverse driving body is installed on a portal frame cross beam of the flame thermal cutting groove head mechanism device, the transverse driving body can be limited along double guide rails on the portal frame cross beam through a transverse moving servo motor to allow reciprocating motion of one degree of freedom, an up-down lifting body is installed on the vertical face of the transverse driving body, an up-down moving servo motor is controlled through a system, an up-down lifting housing, a shaft rotating swing arm and an ignition device are driven to vertically move up and down, and meanwhile various cables, gas pipes, oxygen pipes and the like are arranged inside an engineering plastic tank chain and move up and down along with a lifting body. According to the flame thermal cutting groove head mechanism device, automatic flame groove cutting can be effectively achieved, desired groove parts can be formed through one-time cutting, the operation is easy, a system automatically controls linkage of two shafts on the mechanism, and the X shaft, the Y shaft and the lifting Z shaft on the portal frame do not need to compensate for angle deviation.

Description

technical field [0001] The invention relates to a flame thermal cutting bevel head mechanism device, which belongs to the technical field of flame cutting devices. Background technique [0002] Oxygen cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel. The gas flame heats the metal temperature at the cutting point to above the ignition point, and then an excessive high-speed oxygen flow is supplied. Excess oxygen can not only ensure the full combustion of gas and iron, but also rely on its own kinetic energy to blow away the combustion waste. When iron burns, it generates extremely high temperature and releases a large amount of heat. Under the impetus of high-speed oxygen flow, it melts the metal in front of it. At the same time, the molten waste produced by the combustion is blown out of the slot by the high-speed gas, and the melted metal burns again. Melt the metal ahead. In this way, the slit is formed, and the purpose...

Problems solved by technology

[0004] 1. It can only cut the straight line and curved groove in the same parallel plane as the moving direction, and cannot automatically switch the cutting of the straight line and curved groove edge of the intersecting surface of the cutting and moving direction, and cannot cut the groove on the round pipe;

[0005] 2. All cutting bevel angles need to be manually adjusted before cutting, and the correction angle needs to be adjusted repeatedly. The adjustment process is complicated and the precision is low;

[0006] 3. It is imp...
