Portable semi-automatic flame cutting machine

Abstract

The invention discloses a portable semi-automatic flame cutting machine which comprises a body control box and angle-adjustable cutting nozzles. A motor box is fixedly connected to the right side of the top of the body control box, a vertical moving rod penetrates through the right side of the interior of the motor box, a rack is embedded into the left side of the motor box in a connection mode, and a servo motor is fixedly connected to the middle of an inner cavity of the motor box. The invention relates to the technical field of flame cutting machines. According to the portable semi-automatic flame cutting machine, the servo motor and a gear are utilized to cooperate with the rack, and therefore ascent and descent of the vertical moving rod can be accurately controlled, and then the angle-adjustable cutting nozzles can cut wing plates in the mode of being capable of ascending and descending; the angle-adjustable cutting nozzles are arranged on the two sides, and therefore the wing plates on the two sides can be cut at one time even though H-shaped steel is not reversed, the reversing frequency is reduced, and the working efficiency is improved; and meanwhile,the situation that aweb plate part is completely cut off can be guaranteed, a guide rail and other driving structures are omitted by the machine, and therefore the overall weight of the machine can be greatly reduced, and the machine is convenient to carry and operate.

Description

technical field [0001] The invention relates to the technical field of flame cutting machines, in particular to a portable semi-automatic flame cutting machine. Background technique [0002] Flame cutting machine is a kind of cutting equipment that uses gas with oxygen or gasoline with oxygen to cut metal materials. Mainly used in heavy industry. It is mainly divided into early manual cutting (commonly known as oxygen welding) and semi-automatic cutting machines, profiling cutting machines and CNC cutting machines. With the progress of society and the development of science and technology, they are becoming more and more advanced and their cutting functions are becoming more and more powerful. The general model structure mainly includes: manual profiling cutting machine, portable CNC cutting machine, cantilever CNC cutting machine, gantry CNC cutting machine, desktop CNC cutting machine and intersecting line CNC cutting machine specially used for steel pipe intersecting lin...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a portable semi-automatic flame cutting machine, which solves the problem that the existing semi-automatic flame cutting machine is heavy and inconvenient to carry and operate, and is limited by the structure of the cutting nozzle during cutting. The cutting stroke cannot reach both ends, and the remaining 100mm at each end cannot be cut. It is more troublesome to use a manual cutting torch to complete the cutting. At the same time, when cutting the H-shaped steel, it is necessary to turn the H-shaped steel 3 times, which greatly affects the work efficiency.
