Description
Technical Field
The utility model belongs to the technical field of the material processing, concretely relates to gas cutting point firearm.
Background
Steel structures are the spine and skeleton of almost all structures, but steel structures need to be made from section steel through cutting and welding processes. The cutting of the existing steel structure mainly adopts modes such as laser cutting, plasma cutting and gas cutting, and the gas cutting becomes the current main cutting mode due to low cost, convenience, rapidness and high efficiency. The gas cutting can cut steel plates with the thickness of more than 8 mm, mainly linear cutting, and can also perform circumferential cutting with the diameter of more than 200 mm, bevel groove cutting and V-shaped cutting.
The combustion agent used for gas cutting is mainly from acetylene, propane, natural gas, liquefied petroleum gas, coal gas, hydrogen and the like, and the oxidant is mainly from high-pressure oxygen. The gas cutting needs to be ignited firstly during working, and the ignition tool at the present stage mainly adopts a conventional household lighter. The ignition modes are divided into manual ignition and semi-automatic ignition. When the hand-operated ignition is carried out, only the gas-cutting combustion agent is started, then the gas is ignited in the air, in this case, the combustion temperature is about 210 ℃, although the flame is bright, the impulse is insufficient, the ignition risk is small, and when the lighter is used for ignition, hands can be burnt due to improper operation. When semi-automatic ignition is used, the quick-opening valve is opened before ignition, pure oxygen and acetylene are mixed according to the stipulation of a combustion agent and an oxidant, and the flame temperature can reach 3600 ℃ instantly by igniting in the mode. When the ignition tool is ignited, the ignition tool is too far away from the muzzle and cannot ignite, and the ignition tool is too close to the muzzle, so that the burning flame can burn the back of fingers and hands, and personal injury is caused. Therefore, there is a need to develop a gas cutting igniter that can safely ignite to meet production safety requirements.
