Description
Technical field
The invention belongs to equipment slipping tail apparatus technical field, particularly to a kind of all positon carbon arc gouging gun.
Background technology
The ultimate principle of carbon arc air gouging is: utilizes the high-temperature electric arc produced between carbon electrode and metal by Zone Heating For Metal to molten state, utilizes compressed-air actuated high velocity air that molten metal is blown off simultaneously, thus realizing metal, weld seam are planed and cut.Carbon arc air gouging is generally adopted DC source, and compressed-air actuated airflow direction is consistent with electric arc direction.In planing or working angles, along with the movement of carbon electrode, fusing metal is constantly blown off by air-flow, and compression air serves again the effect of cooling carbon electrode simultaneously, to reduce the scaling loss of carbon electrode.
In the welding process of pressure vessel manufacturing and spherical storage tank, large oil tank, nonstandard storage tank etc., it is required for carrying out back gouging in order to ensure weldquality.Back gouging mostly adopts carbon arc air gouging to complete, and existing carbon arc gouging gun result of use is undesirable, especially during equipment wall thickness >=20mm, back chipping effect is worse, its main manifestations has: existing carbon arc gouging gun broadly falls into jaw type sidewall air supply formula gouging torch, the upper carbon rod of pincerlike folder, carbon rod side is provided with the aperture of three Φ 1.5mm, and compression air output is limited, and air-flow blowing force does not reach requirement；Owing to compression air blows out from side, being only applicable to the gouge of horizontal position, downhand position weld seam, for the weld seam of vertical position of welding, side back chipping is more satisfactory, opposite side back chipping is relatively difficult, if overhead position is just more difficult to implement, it is particularly unsuited for the spherical storage tank that tank skin is thicker；For big thick workpiece, it is necessary to major diameter carbon electrode and big electric current, owing to this carbon arc gouging gun can not use big electric current so that it is such needs can not be met；Owing to compression air drain position output unreasonable, gas is limited, metal liquid slag in molten bath is purged unclean, cause that part carburized metal remains in weld seam, also can form " folder carbon ", the carbon amount contained in the metals in weld seam is made to sharply increase, as polishing cleaning totally can not cause very big hidden danger of quality.
Summary of the invention
It is an object of the invention to provide all positon carbon arc gouging gun that a kind of simple in construction, flexible, scope of application width easy to use and production efficiency are high.
For achieving the above object, the technical scheme is that a kind of all positon carbon arc gouging gun, the air-bag shell connected including end and air bag inner sleeve, air-bag shell inwall and air bag outer wall of inside race enclose ring-shaped gasbag, air-bag shell sidewall is provided with airway, and airway is provided with power supply connecting plate；Being equipped with carbon-point warehouse inside air bag inner sleeve, threadeds with the adjusting nut above air bag inner sleeve in carbon-point warehouse upper end；Carbon-point warehouse lower end is provided with elevator, and elevator outer surface and air bag inner sleeve lower port adapt, and elevator offers carbon-point locking slot；Air bag inner sleeve lower end is provided with the venthole being circumferentially distributed around elevator.
Described carbon-point locking slot is four, and four carbon-point locking slots are distributed on elevator.
Described venthole lower end tilts to elevator direction.
Described air-bag shell and airway material are mild steel, and air bag inner sleeve material is red copper, and elevator material is pyrite.
Compared with prior art, the invention have the advantage that
1, the present invention includes air-bag shell and the air bag inner sleeve that end connects, and air-bag shell inwall and air bag outer wall of inside race enclose ring-shaped gasbag, and air-bag shell sidewall is provided with airway, and airway is provided with power supply connecting plate；Being equipped with carbon-point warehouse inside air bag inner sleeve, threadeds with the adjusting nut above air bag inner sleeve in carbon-point warehouse upper end；Carbon-point warehouse lower end is provided with elevator, and elevator outer surface and air bag inner sleeve lower port adapt, and elevator offers carbon-point locking slot；Air bag inner sleeve lower end is provided with the venthole being circumferentially distributed around elevator, its simple in construction, and gun body is lightweight, it is simple to carry, easy to use flexibly, it is adaptable to face upward position, transverse presentation and upright position, be greatly improved production efficiency, advantageously ensure that construction quality；And operator's technology is less demanding, it is simple to promote.
2, being provided with, in air bag inner sleeve lower end, the venthole being circumferentially distributed around elevator, venthole lower end tilts to elevator direction, can form uniform circumferential flow from the compression air of venthole blowout around carbon-point, makes carbon-point cooling uniformly；During planing, slag can blow off from channeling in time, and channeling front end is piled up without slag, it is simple to see channeling direction clearly, is suitable for various position operation, and can reach desirable.
