Abstract
The invention discloses a technology for welding k-gold jewellery, the technology is as follows: under the work environment with the temperature of 15-25 DEG C and the humidity being less than or equal to 60 percent, two or more pieces of k-gold jewellery semi-manufactured products are set level and the welding positions thereof are aligned. The outer flame of welding flame with the temperature of 1070+/-5 DEG C is used for melting the welding position of each k-gold jewellery semi-manufactured product so as to realize the rapid heat sealing and welding. Furthermore, ratio of weld formation is controlled within 1-1.2. The welding technology is adopted for effectively ensuring the relative purity of gold in the jewellery. The welded jewellery has no welding spot and has smooth surface; meanwhile, energy conservation and consumption reduction can be achieved, welding power can be saved and the production efficiency can be increased.
Description
Technical field
The present invention relates to a kind of gold jewelry process technology, especially relating to a kind of employing ten thousand pure golds is the welding procedure of materials processing jewellery.
Background technology
So-called ten thousand solid gold jewelries are meant that gold jewelry finished product quality meets or exceeds 99.99% jewellery.People are in the processing of pure gold gold jewelry, adopt the mode of use welding powder or welding rod to weld to the welding of jewellery more, carry out the welding of jewellery and adopt with upper type, form big solder joint easily, the processing that is not easy to subsequent handling is handled, production efficiency is low, and it is not attractive in appearance, especially adopt when carrying out the welding of jewellery because there are difference in the composition and the solid gold jewelry of welding powder or welding rod with upper type, this also can reduce the quality of solid gold jewelry, and this phenomenon is processed at ten thousand solid gold jewelries more than 99.99% for quality, particularly evident, influenced the quality of ten thousand solid gold jewelries and attractive in appearance.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of jewellery quality after can effectively guaranteeing to weld, can make simultaneously welding back jewellery not have big solder joint again, smooth surface is mellow and full, but also can save energy, save welding powder, the pure gold ornament article welding technique of enhancing productivity.
For solving the problems of the technologies described above, technical scheme of the present invention is: pure gold ornament article welding technique, employing is under the working environment of 15 ℃～25 ℃ of temperature, humidity≤60%, set level with solid gold jewelry semi-finished product up to ten thousand and the welding position is alignd for two or two with the needs welding, the flame envelope that adopts 1070 ± 5 ℃ of weldering flames is with the half-finished weld fusing of each ten thousand solid gold jewelry, realize rapid welding welding, and aspect ratio of weld is controlled between 1～1.2; The control of working environment in the operating room when control of working environment is meant welding, the control of its temperature and humidity also can suitably be adjusted according to practical condition, as suitable adjustment temperature is 30 ℃, 12 ℃, adjust humidity and be 65% etc., this is known general knowledge to those skilled in the art; And ten thousand solid gold jewelry semi-finished product can press design drawing for adopting raw material, adopt mould to pass through and make after operation such as material is opened in operation such as oil pressure, casting or employing.
The employing of welding flame can look the jewellery volume varies in size and the jewellery kind selects to use the flame of gasoline welding gun or hydrogen-oxygen welding gun, employing at the uniform velocity is burned to 1070 ± 5 ℃ mode with the flame of gasoline welding gun or hydrogen-oxygen welding gun, and the adjustment weld heat input remains on 200～220 joules/cm.And can adopt leftward welding or rightward welding method according to the welding custom.
When welding, weld flame and move with 1cm/s speed, to realize the welding position evenly the being heated raising welding quality along jewellery welding position trend.
Ten thousand pure gold raw materials employing quality is 99.999% gold, and this ten thousand pure golds raw material in use adopts wrapping paper to isolate to guarantee quality.Owing to operations such as getting the raw materials ready of ten thousand pure golds require strict more than thousand pure golds, pure gold, so necessary thoroughly polished and cleaned such as employed process equipment such as mould, the impurity that does not have any other, for guaranteeing the purity of ten thousand pure golds, all processing machines must use a cover separately, be not subjected to the influence of other products with the quality that guarantees ten thousand pure golds, and raw material can not directly contact the material that other can have influence on quality in the operation process, must isolate with wrapping paper, even some more special product, mould also will use once polishing immediately once, requires strictness very.
Ten thousand solid gold jewelries after the welding need carry out surface treatment again, keep aesthetics so that make the jewellery finished product, and surface-treated equipment mainly contains polishing machine, steam engine, sand-blasting machine, pattern-etching machine etc., and instrument mainly contains the agate cutter and steel presses and smooth.Employing at first utilizes polishing machine to carry out polishing and makes jewellery surface generation gloss, go out various beautiful decorative patterns by designing requirement car flower at jewellery surface car with pattern-etching machine then, adopting the concentrated sulfuric acid to soak the jewellery surface is carried out degreasing or impurity afterwards again handles, adopt agate cutter or steel to press and smooth the polishing jewellery at last and carry out the polishing processing, make jewellery surface-brightening such as mirror.And can adopt steam engine to carry out the steam cleaning, and can adopt sand-blasting machine that the jewellery surface is handled by designing requirement according to needs of production, to obtain and the diverse rough surface of jewellery glossy surface, strengthen the attractive in appearance of jewellery with texture.And temperature is controlled at 300 ± 5 ℃, jewellery soak time 30 ± 2 seconds when adopting the concentrated sulfuric acid to soak.
Adopt pure gold ornament article welding technique of the present invention, product can not reduce quality because of the circulation in technological process, has effectively guaranteed the quality of jewellery, welds more completely relatively, and whole the lines flow smoothly, one integrated mass.Ten thousand solid gold jewelries after the welding do not have big solder joint, and smooth surface is mellow and full, the quality of ten thousand solid gold jewelries and attractive in appearance, but also can save energy, save welding powder, enhance productivity.And this soldering technology not only can be applied in the welding of ten thousand solid gold jewelries such as bangle, pin chain, necklace, bracelet, and also can be widely used in other is in the products such as various pure gold ornament articles, handicraft and goods of furniture for display rather than for use of raw material production with ten thousand pure golds.
