Abstract

The invention belongs to the technical field of metal flame cutting processing and provides an oxyhydrogen flame numerical control punching and cutting process. The oxyhydrogen flame numerical control punching and cutting process is characterized in that oxyhydrogen is adopted as cutting gas of a numerical control flame machine tool, the oxyhydrogen is delivered to a cutting torch (6) of the numerical control flame machine tool through a busbar (5), the pressure of the cutting gas is controlled to be in a range from 0.1MPa to 1.6MPa in a numerical control manner, and is gradually increased from low to high. The oxyhydrogen flame numerical control punching and cutting process adopts the oxyhydrogen and a gradually pressurizing mode to perform metal cutting, and solves the problem of serious pollution and potential safety hazards of the traditional process.

Description

technical field

[0001] The invention belongs to the technical field of metal flame cutting processing, and relates to a hydrogen-oxygen flame numerical control punching and cutting process. Background technique

[0002] The existing CNC flame drilling uses oxyacetylene flame as the cutting gas. Because acetylene is flammable and explosive, there are safety hazards in the process of production, transportation, storage and use, and it will cause serious environmental pollution and harm the health of the operator.

[0003] In the process of the flame drilling process of the existing technology, the pressure parameters of the high-pressure cutting oxygen are all preset before the flame drilling, and the pressure during the drilling process is constant, often in thick plate drilling ( Such as: when ≥40mm steel plate) has not yet been pierced, due to the obstruction of oxygen flow, reverse pressure will be generated, and anti-slag will block and burn the cutting nozzle, causing t...
