Description
Affiliated technical field
The utility model relates to a kind of automatic ignition welding and cutting torch of welding field in the machining, and the novel welding torch of this kind is specially adapted to the manual gas welding and the gas cutting of various metal materials, also is applicable to semi-automatic and automatic flame cutting machine.
Background technology
Even to this day, all gas flame welding torch and cutting torch are to adopt manual igniting all, just use match, lighter or the igniting of other burning things which may cause a fire disaster.The shortcoming of this kind ignition method is time-consuming, expense gas, and inconvenient operation is especially when frequent interrupted welding; Or when the welding of high-altitude; Or under outdoor adverse weather condition during (rain, wind, humidity) welding, its shortcoming is more outstanding.
Summary of the invention
The purpose of this utility model is to avoid the weak point of above-mentioned existing welding torch and a kind of novel automatic ignition welding and cutting torch that provides, and the utility model is easy to use, and igniting is quick, makes simple, with low cost.
The utility model is finished in the following manner: it is made up of welding torch, wireway (1), air valve (2), tracheae (3), ignition burner (4), piezoelectric ceramics impulse generator (6), lead (7), ceramic insulating tube (8), spark point (9) and the protective cover (5) of standard.Wireway (1) and injecting tube (16) or mixture pipe (17) communicate, when having mist to pass through in the injecting tube (16), part gas is just by way of wireway (1), air valve (2), tracheae (3), spray by ignition burner (4), if start piezoelectric ceramics impulse generator (6) this moment, just have electric pulse to make spark point (9) produce spark through lead (7), the mist that this spark just in time will spray from ignition burner (4) is lighted, and this flame is called ignition flame.Ignition flame moment just ignites the mist of ejection in the tip (18), thereby finishes the automatic igniting of welding torch.Because piezoelectric ceramics impulse generator (6) and air valve (2) have adopted linked switch, when occlusion pressure electroceramics impulse generator (6), air valve (2) is also closed automatically, and ignition flame is from horizontal blanking.
The utility model has been compared following advantage with existing welding torch:
1. igniting is quick, easy to use.As long as start linked switch, welding torch moment just can light automatically.
2. saving welding gas.Ignition process is long more, and the welding gas loss is many more, not only causes economic waste, and contaminated environment.
3. it is reliable and stable to light a fire.Piezo ceramic element is influenced by climatic environments such as humidity, wind, rain hardly.
4. the utility model improves on the basis of existing welding torch, and structure is lightly practical, makes simple, with low cost.
