Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal processing flame cutting flat rack. Background Art

[0002] Flame cutting is a common method for rough processing of steel plates. Flame cutting usually uses a mixture of acetylene and oxygen. The mixed gas is ignited through a nozzle to form a high-temperature flame. The working principle of flame cutting can be divided into two main steps: preheating and cutting. In the preheating stage, the flame is used to heat the surface of the metal workpiece to a sufficient temperature for subsequent cutting. During preheating, the flame nozzle is adjusted so that the flame produces an appropriate working temperature from the inside, generally around 3000 degrees Celsius.

[0003] At present, before flame cutting, steel plates are usually placed on a flat rack to facilitate flame cutting. However, the flat rack lacks a mechanism to limit the position of the steel plates. When flame cutting the steel plates, the steel plates are prone to deviation, making it difficult to ensure stability during the cutting process. Utility Model Content
