Wallboard structure of heat radiating fin trimming machine

Abstract

The invention relates to a wallboard structure of a heat radiating fin trimming machine, belonging to the field of processing equipment of a finned heat radiator of a transformer. The heat radiating fin trimming machine comprises an engine base, heat radiating fin side limiting mechanisms, one group of upper pinch roller mechanisms, heat radiating fin burr rolling mechanisms, a heat radiating fin leading-in clamping mechanism, one group of lower pinch roller mechanisms and a power transmission mechanism, wherein the wallboard structure comprises a pair of wallboards. The wallboard structure of the heat radiating fin trimming machine is characterized in that the wallboards are respectively provided with one group of first allowing holes and one group of second allowing holes in the length directions, the quantity of the heat radiating fin side limiting mechanisms is equal to the quantity of the first allowing holes and are fixed with the wallboards, the quantity of the heat radiating fin burr rolling mechanisms is equal to the quantity of the second allowing holes and are fixed with the wallboards, the heat radiating fin leading-in clamping mechanism is arranged between the wallboards, and the power transmission mechanism is arranged on one side of the base in the length direction and is in transmission connection with the lower pinch roller mechanisms. The wallboard structure has the advantage that the heat radiating fin side limiting mechanisms and the heat radiating fin burr rolling mechanisms are arranged reasonably, thus a modularized effect is developed.

Description

Technical field [0001] The present invention is the technology field of transformer sheet radiator processing equipment, which involves a wall plate structure that specifically involves a radiator. Background technique [0002] As the industry knows, in order to make the transformer (oil immersion transformer) run normally, it is usually necessary to set the radiator on the side and / or upper part of the transformer.It is composed of multiple heat sinks, which can be fully understood by this patent technology solution that is not limited to the following and publicized patent literature.Such as CN201084519Y (chip radiator for transformer), CN101339838A (radiator ladder radiator), CN201185118y (radiator of transformer), CN201185115Y (radiator with wind machine seats), CN201185117y (chip radiator for transformer),CN201256051Y and CN101388275A (transformer heat exchanger with evaporative cooling technology), and so on. [0003] Furthermore, as in the industry, during the processing o...

Problems solved by technology

However, after cutting off the residual margin or trimming at the edge of the heat sink, very sharp burrs and flanging are often left at the trimming position.

Therefore, in order not to affect the subsequent process, for example, in the process of transferring to the subsequent process, the operator's limbs will be damaged due to burrs and unsafe accidents will be caused, so it is necessary to deal with the aforementioned burrs and flanging.

[0004] In the prior art, workers use a polishing device or similar devices to polish the burrs remaining on the heat sink. The disadvantage of this treatment method is that : One is that the worker’s work intensity is high; the other is that the work efficiency is low; the third is that there is still the risk of injuring the worker’s limbs during the polishing process; After trimming, workers need to transfer the heat sink to the polishing equipment, so continuous production cannot be reflected

[0005] Undoubtedly, if a well-structured hemming machine is used, the above-mentioned problems can be eliminated, but there is no corresponding For example, the "closed radiator rolling machine" recommended by CN2031318U revolves around the flanging of radiator fins; the "chip radiator radiator fin rolling forming machine" provided by CN2223661Y is used for the molding of radiator fins; CN201223908Y The "transformer heat sink rolling forming automatic line" introduced is also used to make heat sinks
