Description

The fin positioner of edge welding machine for radiating fins

Technical field

the invention belongs to electroplating equipment wielding machine technical field, be specifically related to a kind of fin positioner of edge welding machine for radiating fins.

Background technology

as is known in the industry, in order to make transformer (oil-filled transformer) be able to normal operation, conventionally need to radiator be set at the sidepiece of transformer and/or top, by radiator bear the responsibility make transformer temperature rise decline effect, to this can by be not limited to by exemplify below and be fully understood by the disclosed patented technology scheme of Chinese patent literature.As CN201084519Y(fin type heat radiator for transformer), CN101339838A(stair type heat radiator of heat radiating fins), the radiator of CN201185118Y(transformer), CN201185115Y(has the radiator of fan seat), the gilled radiator used of CN201185117Y(transformer), CN201256051Y and CN101388275A(adopt the transformer heat exchanger of evaporation cooling technique), etc.

and then as is known in the industry, transformer gilled radiator is formed by one group of fin set, and each fin is equated by a pair of shape formed objects and forward and backward of combining face-to-face forms, can be referring to the energy-saving isothermal radiating fin of CN201199475Y(transformer radiator to this) and the fin of CN201185119Y(transformer radiator).From the heat radiating fin structure that is not limited to these two patents announcements, because the shape at its (fin) two ends is splayed substantially, therefore very trouble of welding.Do not there is because implement the fin conveying mechanism of welding for fin being delivered to welding mechanism the function that the welding position of fin is clamped, and fin conveying mechanism must and welding mechanism between keep enough distance, otherwise can Yin Gaowen in the time that welding mechanism welds and undermine conveying mechanism.Especially because the shape at the two ends of fin is special, be aforesaid splayed (also can claim herringbone), thereby be difficult to adopt suitable technological means to be clamped, if be short of and do not clamp or clamp effect in welding process, can have a strong impact on so welding quality, even cause and scrap.For this reason, the applicant has done positive and useful design, finds a way to resolve the problem, and tests in the applicant unit under strict secrecy provision, it is practicable that result proves, and technical scheme described below produces under this background.
