Abstract
The invention relates to a high-efficiency plasma brazing gun head. Since the temperature of a plasma flame brazing center is approximate to tens of thousands DEG C, the guarantee for insulation of a gun body and a cathode column becomes the key of the plasma brazing gun head. The high-efficiency plasma brazing gun head is characterized in that the cathode column is designed into a spiral tooth shape, the ceramic and high-temperature-resistant insulating glue are coated on the surface of the cathode column, and then the cathode column is bonded together with the gun body so as to form a cooling water channel directly between cathode column teeth and the gun body, so that the cooling effect is finished furthest and the long-term working of the plasma brazing gun head is guaranteed.
Description
Technical field
The present invention relates to a kind of high efficiency plasma soldering gun head, can satisfy new product, the new invention of energy-conservation, safety and environmental protection.
Background technology
In existing plasma welding connection technology, mainly be plasma arc welding (PAW), belong to molten solder.And soldering needs combustion gas and oxygen, in the age of energy shortage, awareness of safety and environmental requirement, is badly in need of a kind of new technology and equipment that soldering is carried out in combustion gas that replaces.High efficiency plasma soldering gun head is a critical component of realizing the plasma torch soldering.
Summary of the invention
The technical problem that the present invention solved is to provide a kind of simple in structure, high efficiency plasma soldering gun head of satisfying the soldering requirement.This high efficiency plasma soldering gun head comprises plasma arc apparatus, brazing flame device, cooling device.Whole process cooling device fully cools off guarantees keeping of plasma brazing flame.The present invention is designed to screw serrated form to cathode column, and surface-coated pottery and high-temperature insulation glue are bonded together with high-temperature insulation glue and rifle body again, let cooling water pass through from cathode column between cog and rifle body.Can fully cool off rifle body and cathode column, guarantee that plasma soldering gun head at high temperature can long-term work.
Description of drawings:
Fig. 1 is the main cutaway view of high efficiency plasma soldering gun head of the present invention.
The specific embodiment
Elaborate below in conjunction with the accompanying drawing specific embodiments of the invention:
Shown in Fig. 1, this high efficiency plasma soldering gun head comprises plasma arc apparatus, brazing flame device, cooling device.Plasma arc apparatus is made up of cathode wire fixed screw 1, cathode column 13, insulator 6, cathode taps 7 and nozzle 8; Insulator 6 possesses different length to be changed, and adapts to the welding different workpieces; The brazing flame device comprises air inlet 5 and pore 9; Cooling device comprises rifle body 10, cooling water channel 3, water inlet 4, delivery port 2 and cathode column 13; Cathode column 13 surfaces are profile of tooth in the shape of a spiral; The insulating ceramics that surface-coated one deck is thin, ceramic surface applies high-temperature insulation glue again, forms high-temperature insulation mixed layer 12; Be bonded together with high-temperature insulation glue 11 and rifle body 10, rifle body and cathode column between cog are formed cooling-water duct 3 again; Under the effect of plasma arc power supply main frame, the plasma arc apparatus of high efficiency plasma soldering gun head produces plasma arc, and the brazing flame device produces the plasma brazing flame under plasma arc helps simultaneously, forms the required thermal source of soldering.Because nearly ten thousand degree of plasma brazing flame central temperature, nozzle 8 sharply rises with cathode taps 7 temperature, and cathode column 13 also sharply rises with rifle body 10 temperature; Cooling water is from water inlet 4 simultaneously; Getting into cooling-water duct 3, see through very thin pottery and high-temperature insulation glue mixed layer 12 large tracts of land cooling cathode column 13, then is direct cooling to rifle body 10; Play maximum cooling effect, fully guaranteed the long-term work of plasma soldering gun head.
