Abstract
The invention relates to a manufacturing method of a gas cutting opening. The method is that stainless steel is manufactured indoor powder less than 40 microns by the stainless steel spray powdering method; the powder is mixed with adhesive to be manufactured into particles; the particles are processed by metal injection molding to obtain the shape as requirement and then is degreased and heated and formed at high temperature under vacuum; the sealing surface is grinded to obtain the gas cutting opening. According to the method, the stainless steel is used, instead of copper, for preparing the gas cutting opening, so that the gas cutting opening is suitable for mass production, the cost is basically the same as the copper cutting opening, and a large amount of copper resources can be saved; meanwhile, the cutting processing is basically saved, and thus a large amount of metal processing devices and labors can be saved; the service life of the stainless steel cutting opening is about 10 times that of the copper cutting opening, so that the overall cost is about 1/10 of that of the copper cutting opening, and meanwhile, a large number of use cost can be saved; the influences such as frequent mechanical cutting opening replacement on production can be removed; the traditional manufacturing method of the gas cutting opening is completely changed, and large economic benefit and social benefit are brought.
Description
Technical field
The present invention relates to a kind of manufacture method of gas cutting torch.
Background technology
Gas cutting torch is industrially widely used, and comprises combustion gas (acetylene, propane etc.) cutting torch, plasma cutting torch etc., is the indispensability of cutting steel plate, iron plate, copper coin and other metal materials.Be divided into again hand use, machine with two kinds according to national standard gas cutting torch, hand G01-100 cutting torch 3 kinds of models, hand G01-30 cutting torch 3 kinds of models, hand G01-300 type has 6 kinds of models, Welder cutting nozzle has 8 kinds of models, the U.S., each specification requirement of having oneself by oneself in Europe.According to investigations, the annual gas cutting torch demand in the whole nation is about 500,000,000, and be all copper, about copper consumption is 30,000 tons, and the demand about 2,000,000,000 in the whole world, copper consumption is approximately 120,000 tons.During cutting steel plate, the slag that fusing is splashed, if fly to the gas outlet of cutting torch, or encountered steel plate by the cutting torch that flame heat regulating softens, copper cutting torch is easy to distortion or blocking, affects the ejection shape of gas port place gas, thus the flame of ejection is out of shape, normally carrying out of impact cutting.If use stainless steel cutting torch instead, because stainless steel has higher fusing point, and avoid the rapid wear phenomenon of gas outlet, lasting high-temperature heating is also not easy to make stainless steel softening transform, thus greatly improves the service life of cutting torch.Cutting torch adopts the main cause of copper material to be because copper material is softer, facilitate the shape that machining becomes complicated, and stainless steel is harder, is difficult to the shape of machining complexity.But China is a poor copper country, and copper belongs to non-ferrous metal, and resource is closely exhausted, and copper material price is stainless 3-4 times.Stainless beginning fusion temperature is at 1500 ° of more than C, and the fusing point of red copper is 1080 ° of C, well below stainless fusion temperature.
Summary of the invention
For the deficiency that prior art exists, the present invention adopts the efflorescence of stainless steel water smoke stainless steel to be made the powder being less than 40 microns, by with plastic binder be mixed and made into particle, shape needed for metal injection molded one-tenth, pass through degreasing again, vacuum high-temperature hot briquetting, sealing surface wears into obtained stainless steel gas cutting torch, and the life-span is about 10 times of copper cutting torch.
Technical scheme of the present invention is: a kind of manufacture method of gas cutting torch, and manufacture method comprises:
(1) stainless steel water atomization or aerosolization powder is chosen.
(2) mixed according to volume ratio with binding agent by stainless steel powder, feeding is made in banburying, extruding pelletization.
(3) according to the size of the gas cutting torch of prescribed by standard and structure fabrication injection moulding mould used, the requirement preparing die size be according to blank sintering after shrinkage factor, utilized by feeding injection (mo(u)lding) machine to inject mould molding, die sinking is blank after taking out.
(4) blank is removed the binding agent in goods through the way of soaked with liquid or heat resolve.
(5) by remove the goods after binding agent carry out high temperature sintering densified after obtain sintered article.
(6), after sintered article being carried out multiple post processing as required, be installed together and obtain final gas cutting torch.
Optimally, stainless structure is austenite, and model comprises 304 and 303, and particle diameter is less than 40 microns.
Optimally, stainless steel powder mixes with the volume ratio of binding agent according to 1 ~ 0.5:1.5.
Optimally, binding agent comprises the two or more composition such as polyethylene, polypropylene, EVA, polyvinyl alcohol, polymethyl methacrylate, stearic acid, polyethylene, paraffin.
Optimally, sintering temperature is 1100 DEG C ~ 1600 DEG C.
Optimally, density reaches 95% ~ 98% of stainless steel density.
Beneficial effect is, the present invention adopts the efflorescence of stainless steel water smoke stainless steel to be made the powder being less than 40 microns, by with binding agent be mixed and made into particle, shape needed for metal injection molded one-tenth, again by degreasing, vacuum high-temperature hot briquetting, sealing surface wears into obtained gas cutting torch.This invention with stainless steel replace copper for gas cutting torch, be applicable to produce in enormous quantities, cost and copper cutting torch basically identical, saved a large amount of copper resource; Simultaneously because the method is substantially without machining, a large amount of metal-working plants and manpower are saved, due to about 10 times that the stainless steel cutting torch life-span is copper cutting torch, therefore overall cost is only about 1/10th of copper cutting torch, also can save a large amount of use cost, such as Welder cutting nozzle changes the impact etc. on producing frequently simultaneously.Therefore the preparation method traditional to gas cutting torch is produced subversive change by this invention, by the huge economic benefit of generation and social benefit.
The present invention adopts austenite as material, and because austenite does not have magnetic, during cutting, iron filings are not easily adsorbed on cutting torch, effectively ensures the normal use of cutting torch, can not block, and extends cutting torch service life.
