Description

The edge welding machine for radiating fins of radiator

Technical field

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

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.Particularly can only be by means of manual welding owing to lacking suitable automatic welding machine reply.The self-evident shortcoming of manual welding is: electric welder's labour intensity is large, welding efficiency is low and welding quality is difficult to ensure.

even if be also difficult to cook up the bonding machine that is met the fin welding requirements to aforementioned shapes under the enlightenment of the technology contents of " electric heater cooling fin welding machine " recommended such as Chinese patent utility model Granted publication CN201950359U and CN201493618U " a kind of dedicated welding machine for radiators " that provide.In addition, according to common practise, as the edge welding machine for radiating fins with automatic welding function mainly by frame, automatic welding mechanism with form for the fin conveying mechanism that the fin for the treatment of toe is carried towards automatic welding mechanism direction, and fin conveying mechanism is the important component part of edge welding machine for radiating fins, because should ensure fin steadily goes and moves towards automatic welding mechanism direction, avoid again fin sideslip, also to prevent that the jumping phenomenon of quivering from appearring in fin in traveling process, otherwise be difficult to guarantee toe quality.Can make fin guarantee all the time the linearity technology enlightenment that steadily row moves but be not seen in prior art, for this reason, the applicant has done positive and useful design, find a way to resolve the problem, and test in the applicant unit under strict secrecy provision, it is practicable that result proves, and technical scheme described below produces under this background.
