Have a delivery device 4, delivery device 4 is contacted with the consumable accessories 5 in the second lock chamber 12 so that consumable accessories 5 always with limit
Position portion 3 contacts.
The electrode for plasma arc cutting torch that the embodiment of the present invention is provided, with the consume of consumable accessories 5, delivery device
The 4 remaining consumable accessories 5 of push are contacted with limiting section 3, until consumable accessories 5 is worn away completely, after consumable accessories 5 has consumed, will be consumed
Damage part fixed part 2 is unloaded from electrode body 1, and new consumable accessories 5 is packed into the second lock chamber 12, in delivery device 4 and limit
It is fixed under the action of position portion 3 in second lock chamber 12.Therefore, compared with prior art, when consumable accessories consumes completely not
Need replacing entire electrode so that the service life of electrode greatly improves, so that use cost substantially reduces；Again due to consumption
Part is damaged during consume, is contacted under the action of delivery device with limiting section, therefore, starting the arc effect is good.
Consumable accessories 5 in the embodiment of the present invention is preferably hafnium filament or tungsten filament.
Wherein, delivery device 4 includes elastic component 41 and top bracing member 42, and one end of elastic component 41 is placed in the first lock chamber 11
Interior, the other end of elastic component 41 is placed in the second lock chamber 12, and one end of top bracing member 42 is contacted with consumable accessories 5, top bracing member 42 with
Elastic component 41 connects, so that top bracing member 42 has the trend moved to limiting section 3.
When new hafnium filament is put into the second lock chamber 12, top bracing member 42 is contacted with hafnium filament, in the effect of elastic component 41
Under, top bracing member 42 promotes hafnium filament so that hafnium filament is contacted with limiting section 3, and under the action of top bracing member 42 and limiting section 3, hafnium filament is consolidated
It is scheduled in the second lock chamber 12.When new hafnium filament is packed into the second lock chamber 12, elastic component 41 is in confined state, with hafnium filament
It is consumed, becomes smaller gradually to the compression of elastic component 41, in the process, elastic component 41 promotes top bracing member 42 in the second lock chamber 12
Interior movement, so that top bracing member 42 is always in shoring the state of hafnium filament, so as to finally so that hafnium filament is fixed on the always
In two lock chambers 12.
Wherein, the elastic component 41 in the embodiment of the present invention be spring, top bracing member 42 include connecting portion 421, blocking portion 422 with
And top brace part 423, connecting portion 421 are fixedly connected with blocking portion 422, top brace part 423 is fixedly connected with blocking portion 422, spring pocket
It is located on connecting portion 421 and is contacted with blocking portion 422, the one end of top brace part 423 away from blocking portion 422 is contacted with consumable accessories 5.
Under the above constitution so that top bracing member 42 is detachably connected completely with elastic component 41, convenient disassembly.
