Description

The positive-pressure type powder feeder of laser melting coating weldering
Technical field
The invention belongs to plasma spray technical field of auxiliary equipment, and in particular to a kind of positive-pressure type of laser melting coating weldering Powder feeder.
Background technology
As glass mold manufactures known in the art:In the forming process of glassware, for two die sinkings or the glass of many die sinkings For glass mould, glass melt of its die cavity directly with melting is frequently contacted, chemical erosion by glass melt, abrasion and cold Alternating thermal stress(Cold and heat succeed each other transformation stress)Effect, and at a temperature of 500-800 DEG C or so be on active service, cavity surface, Joint surface or even two ends end face are easily aoxidized, and add the shock for existing between mould parts and being difficult to avoid that, thus can be produced not It is limited to following several damage situations:Fatigue damage, mechanical collision damage, oxide etch damage and wear damage.
In order to improve the resistance to oxidation of glass mold, corrosion-resistant, heat-resistant anti-fatigue and the performance such as wear-resistant as much as possible, generally adopt With plasma spray mode to position cladding solder alloy material layers, the material of alloy material layer such as die cavity, the joint surfaces of glass mold The quality % contents that material refers mainly to but is not limited to refer to nickel are more than 90% nickel-base alloy powder.It is preceding during laser melting coating weldering The nickel-base alloy powder stated is generally by special dust feeder(Custom claims " powder feeder ")Conveying.
The technical information of powder feeder can be seen in disclosed Chinese patent literature, it is typical as CN103111736B recommends The alloyed powder of glass mold plasma spray " protection against the tide conveying device ", it is more typical such as CN101372287A offers " machine for transporting powder with multiple-storage hopper " and CN102134715B " a kind of laser cladding multi-bin negative-pressure type powder feeder ".
Although the technical scheme that above-mentioned CN101372287A and CN102134715B is provided has the effect of different Qu Tonggong, There is the logical disadvantage of following two aspects:First, going out powder using negative pressure due to going out powder form, thus need when actually used Powder oral area position(CN101372287A claims " suction powder hopper ";CN102134715B claims " starch sucking nozzle ")Configuration negative pressure ejector, so that Cause structure relative complex;Second, due to the air inlet pipe for needing to be pointed in powder feeding cylinder during actual powder feeding (CN101372287A claims " gas blow pipe ")Air inflow controlled, although CN102134715B is in the 0038th section of its specification It is 5-150g, powder feeding stability ± 2%, alloy powder splendid attire to describe into powder gas atmosphere >=0.3MPa, powder sending quantity adjustable range 20-150 μm of amount 1.1L/ and powder feeding granularity, but do not provide the technical inspiration of the relevant apparatus that gas is provided to feeding cylinder.
