Furniture has now become a synonym for fashion elements. Now home decoration with a lot of metal furniture, that is very fashionable, very avant-garde. In the previous few years, there are few Chinese consumers of metal furniture, Chinese people like that time is a wooden furniture, that may be the traditional Chinese people leave things! In the nearly two years younger generation in favorite furniture has occurred great changes, more like the wild thing, pay more attention to is metal furniture surface treatment effect. In the market, consumers are more concerned about the effect of metal surface has two kinds: one is electroplating, one is wire drawing. Electroplating in the market has been popular for many years, the production of enterprises is very easy to solve the process, but the wire drawing process for manufacturers to bring a lot of problems. The effect of metal surface drawing requirements of line uniform, Hikaruzawa Youwa, a variety of colors, the visual feel good. From a professional point of view of the process of electroplating are also divided into many kinds of such as: copper, zinc, nickel, etc.. In line type metal will be divided into snow grain, hairline, circular, special pattern. From the line length to also can be divided into long and short.
Here I mainly want to like to discuss about the knowledge processing line.
Most metal furniture manufacturing method is: tube (round), cutting, lined processing, molding, welding, welding process, welding repair, assembly and packaging.
2 snowflake grain processing method is mainly used in the treatment of the surface of the square tube, it is a difficult process, is due to the need to machine and abrasive with, the machine will generally choose the automatic drawing machine, the machine speed not to 900-2400 revolutions per minute (RPM), must to sway in the grinding process, the oscillation frequency for 60-300 times \/ minute. If the only choice to rotate without swing machines after grinding the surface the hairline. And speed and swing frequency determines the snowflake grain effect, also grinding material selection is more important, abrasive has a direct impact on the furniture surface lined vision and the hand feeling effect, according to the current market popular metal furniture, abrasive material is generally small and drawing wheel brush or nylon band selection, particle size is generally use two kinds of CRS, FN.
3 hair pattern processing method: general is the choice of pipe surface processing method, equipment with ordinary flat wire drawing machine, manual drawing machine, the abrasive material selected for small roller brush drawing wheel) and 100 clean cloth two, particle size is generally choose CRS, Med two more. Using the plate drawing machine square tube surface treatment, after forming, solder joint thickness place need to repair on the choice of the angle grinder were treated with 120# zirconia corundum sand disc, also can use 180# sand disc to reduce the welding point roughness using portable polishing machine with a small brush roller, wire drawing wheel) to repair the surface lined, if is lined gloss is not very ideal, our choice of 100 clean cloth to do a simple repair.
4 torus processing method: 100 clean cloth piece of circular tube processing, use the machine to the ordinary small grinder or centerless grinding polishing machine, abrasive, grain size selection CRSMED two more, the circular tube placed in the small grinder to rotate with 100 clean cloth to wipe your hands. The grinding machine is more easy, it automatically grinding to the pipe, the choice of grinding material for the winding wheel or nylon belt two.
5 if there are special requirements of customers can do some pattern in the RHS above, treatment is first with some textured paper to do pattern of local affixed to live, and then a manual polishing machine to drawing, choose to fine granularity of abrasive materials. The general size is VFN or SFN two, so out of line is very soft, tear up the final textured paper is complete.
